How Four Earthquakes in One Day Exposed the Need for Seismic-Resilient Infrastructure

0

A series of powerful earthquakes erupted around the globe in the last 24 hours. On Wednesday, a sequence of powerful earthquakes rattled three continents within a mere eight-hour window, sparking global concern. In Northern California, a 5.6-magnitude tremor struck Mendocino County, knocking out power for thousands and leaving residents shaken but largely unharmed. Hours later, a massive 7.2-magnitude earthquake struck off the coast of Iwate Prefecture, Japan; fortunately, the nation’s highly resilient infrastructure and the lack of a tsunami threat prevented significant damage.

While California and Japan escaped relatively unscathed, Venezuela suffered a profound tragedy. The country experienced a rare earthquake doublet—a rapid succession of 7.2 and 7.5-magnitude quakes that collapsed buildings in Caracas and along the northern coast, claiming at least 164 lives.

According to Associated Press, four powerful earthquakes rocked different parts of the world in less than eight hours on June 25, 2026. Despite public fears that these global events might be physically linked, experts from the U.S. Geological Survey confirmed that the earthquakes occurred on entirely separate fault lines and were simply a dramatic geological coincidence.

The History of Earthquakes in Pakistan

Two earthquakes occurred just over a minute apart in two different parts of Karachi on July 16, raising the total number of low-intensity earthquakes in the city since June 1 to sixty, and making earthquake preparedness a critical concern.

According to data from the Pakistan Meteorological Department, the first earthquake of magnitude 3.4 originated at a depth of 20 km at 5:52 pm. Its epicenter – the point on the ground located directly above the earthquake’s origin – was located 14 km northwest of Malir. This earthquake was followed by a 2.7-magnitude tremor that originated at a depth of 10 km at 5.53 pm. Its epicenter was 10 km east of DHA City on the Super Highway.

Local geologists report that fault lines passing through the areas of Korangi and Malir have become active after several decades and are causing minor earthquakes in the surrounding areas.

Earlier, on March 31, an earthquake of magnitude 4.7 had also rattled Karachi. Although the tremors lasted only a few seconds, they caused widespread panic and disruption in the metropolitan area, revealing the lack of preparedness for natural disasters. This event not only shook the ground but also served as a wake-up call for residents. Also, it highlighted the critical need for disaster management in a vulnerable country like Pakistan.

What Causes Earthquakes in Karachi?

Researchers explain that Karachi lies on a passive margin, a zone where the continent meets the ocean, so the chances of a massive earthquake happening there are low. Small earthquakes do happen with intensities of 3 and 4 on the Richter scale, but they are not dangerous.

Dr. Sarosh Hashmat Lodi, the former Vice Chancellor of NED University of Engineering and Technology, spoke to Dawn about Karachi’s vulnerability to earthquakes. He stated that the city has no significant history of major earthquakes. However, if an earthquake with a magnitude of 5 or 6 were to occur, it could cause substantial destruction due to the inability of the city’s infrastructure to withstand such an event.

Natural disasters like this are, in a sense, natural. We can’t avoid them, but that doesn’t mean we can’t be better prepared when they do come. Before we explore how to prepare for an earthquake, we need to understand why this is even more important for a country like Pakistan!

Why Earthquake Preparedness in Pakistan Cannot Wait

The Earth is made up of huge chunks of rock called tectonic plates – think of these plates as ice cubes floating on the surface of your soda, except that the tectonic plates move extremely slowly: around 2 to 10 centimeters per year. It is when these plates move and collide with each other that an earthquake is born.

Pakistan is situated on the boundary between two major tectonic plates: the Eurasian and the Indian Subcontinent plates. Additionally, it lies on minor plates, such as the Iranian, Arabian, and Tibetan plates, which further increases the risk of experiencing an earthquake. That makes earthquake preparedness in Pakistan not just a precaution, but a necessity embedded in the country’s geography.

Moreover, Pakistan’s landscape is scattered with several fault lines, which are essentially fractures in the Earth’s crust and form when two pieces of land grind against each other, building up huge amounts of pressure. Karachi, in particular, contains the following faults: Karachi-Jhimpir Fault Zone, Allah Bund Fault, Kirthar Fold and Thrust Belt, and Makran Subduction Zone.

Additionally, much of Pakistan’s infrastructure has been developed without accounting for the potential impact of earthquakes. The absence of this consideration in building designs drastically increases the risk of damage associated with seismic events.

Hence, it is safe (or rather, unsafe) to say that Pakistan is not only located in a highly seismically active region in the world, but also lacks the preparations required to minimize damage caused by earthquakes, making it all the more important for us to improve our disaster management system.

Dust, Debris, and Destruction – The Kashmir 2005 Earthquake!

Let’s take the Kashmir 2005 earthquake as an example, and explore the devastating effects of the earthquake, what steps were taken to reduce damage, and evaluate the groundbreaking lessons learned from this tragic event.

The Extent of Devastation!

On October 8, 2005, one of the most devastating earthquakes hit Pakistan with a magnitude of 7.6, resulting in terrible consequences for human life and infrastructure. For comparison, this earthquake was around 800 times stronger than the one experienced in Karachi on March 31.

Shahzeb Jillani, a Karachi-based journalist, then reported to the BBC, “When he reached Balakot, one of the areas greatly affected by the 2005 earthquake, it was a terrible sight: around 90% of the buildings had been reduced to nothing but rock and rubble. Parents screamed their children’s names outside what was once Shaheen School, and the atmosphere was encompassed by a prevalent feeling of helplessness.”

The Aftermath

According to data in a report published by the National Disaster Management Authority (NDMA), between 3.2 million and 3.5 million people were affected by the earthquake, either directly or indirectly. The nation faced 73,000 casualties, while 79,000 people remained injured.

In terms of infrastructural damage, a staggering 400,153 homes were destroyed, leaving hundreds of thousands of people without a roof over their heads. Roads and communication lines were severely damaged, which further delayed a response from emergency teams.

The Response

The government established a Federal Relief Commission (FRC) to initiate and manage large-scale rescue and relief operations. Simultaneously, the Earthquake Rehabilitation and Reconstruction Authority (ERRA) was also formed to support medium- and long-term reconstruction projects. It was through these entities that aid and assistance from international organizations and agencies also poured in. Emergency camps and mobile hospitals were also set up.

The Faults led to more Human Toll and Infrastructure Damage

Several factors led to increased damage to human life and infrastructure as a result of the Kashmir earthquake:

Lack of Planning and Earthquake Preparedness

The absence of an early warning system meant the residents were not prepared to expect an earthquake. In countries like China, where a national early warning system has been set in place, residents can be alerted a few seconds before an earthquake strikes, prepare them before the disaster strikes.

Now you may ask: how does an early warning system exactly work? We all have one friend who stays at the entrance and tells us when the teacher is on their way to the classroom, so that we can stop our mischief! Consider this early warning system to be that friend – it alerts everyone seconds before the earthquake strikes!

Additionally, it is important for organizations like the NDMA to devise a detailed plan to put into action immediately when an earthquake strikes – even the seconds matter in crucial times like these! Survivors of the Kashmir earthquake faced many issues with mismanagement, such as uneven aid distribution and temporary shelters unable to support harsh weather conditions.

Lack of Proper Infrastructure

The Kashmir earthquake brought damage to around 780,000 buildings – but the question is why. This is because buildings in Pakistan are not designed with earthquakes in mind. Following the Kashmir earthquake, several steps were taken to change this: by revising the Building Code of Pakistan (2007) to incorporate ‘seismic provisions’; however, that being said, efforts remain limited in the implementation of this code, highlighting a major gap in earthquake preparedness in Pakistan.

Additionally, many roads and communication lines were damaged due to the earthquake, causing delays in the provision of emergency and rescue services. Remote regions like the Neelum Valley did not receive aid for several days. This issue can be avoided by establishing emergency options for which careful planning is crucial.

Lack of Earthquake Knowledge and Awareness

It has been noticed that several people in the regions affected by the Kashmir earthquake did not have adequate awareness about how to react to an earthquake. Hence, it is important for the relevant government agencies to ensure focus is placed upon earthquake drills and public awareness campaigns, specifically in schools. Community training programs can play a huge role in improving earthquake preparedness in Pakistan, especially in schools and rural areas

Lack of following the Building Code in Pakistan

Earthquakes are a prevalent issue for Pakistan primarily due to its location, as earthquake-prone regions tend to be highly populated, resulting in even greater damage.

In his interview with Dawn, a geologist explained that many buildings in Karachi are constructed with low-quality materials, have no earthquake preparedness, and the safety standards for most of these structures are questionable. Oftentimes, very inexpensive materials are used in their construction.

This makes it imperative for everyone to play their role in reducing damage from earthquakes: government organizations by investing in carefully planned initiatives and programs, schools by educating their students about earthquake management, and communities by being prepared and helping each other when the quakes strike. Strengthening earthquake preparedness in Pakistan at every level is essential to reducing future disaster impacts.

Let’s invest in rock-solid plans for shaky times!

Negativity and its Biological Impact on Our Mental Health

We all experience events in our lives to be cherished, events that give us highs and bring out the livelier sides in us. But as they say, what goes up must come down. The lowest ebbs are also a reality, which we must come to fathom at one point in our lives or another; turbulations, betrayals, and losses, all these can wreak havoc on the sanest of minds and affect mental well-being.

The effects of psychological illnesses and certain personality traits (Type A personalities) are compounded by the situations we face in our daily lives and how we react to them. Not everyone faces the same situation in the same manner. Some are a calm presence in the face of the storm, while others are ruffled by the slightest of gales. Our outlook in life, on one hand, determines how and what decisions we make, while it also determines how we will fare in terms of our health.

Outlook in life, behavior, and mindfulness

How we think and feel is very much part of who we are and is determined mostly by our environmental rearing & conditioning since we were little kids. The responses we build against internal and external stimuli become pretty much part of our repertoire of life skills.  Some of us are being overly optimistic, while others find gloom in nearly every aspect of our lives.  It is well known that psychological/psychiatric illnesses predispose us to a whole host of medical issues, ranging from peptic ulcers to heart disease. Apart from this, our everyday behaviors, which we nurture with our day-to-day experiences, also play a big role in how we are at risk for diseases. 

Undue hatred towards someone, unnecessarily looking down the barrel during the slightest of situations, jealousy, and destructive criticism are just a few examples of negative behaviors and attitudes we all face. When persistently exercised, these become second nature, and our minds become a breeding ground of such values and beget more of the same.

The concept of ‘mindfulness’ is based on being free from the thoughts mentioned above and focusing on the present rather than living in the past or worrying about what’s to come. The future of medicine is very much intertwined with this concept. Preventive medicine should not be based only on healthy eating behaviors and exercise, but rather on integrating a positive outlook in life and a healthy mental state.

How the body reacts to our mental health

Our minds and bodies are intertwined in structure and function. And it is high time that we started dealing with it as such. The body and its intricate processes of immunity, healing, aging, etc., depend upon how our ‘whole’ self reacts to external and internal stimuli. 

Say, when we are going through a rough phase in life, the mental stress mainly causes us to lose or gain appetite, as the case may be, but it can also cause loss of interest in the simplest of things; all this affects our bodies simultaneously. The stress response, which is a ‘code’ as I would like to put it, in our body, gets activated whenever we consciously/subconsciously sense harm, danger, or imminent threat. All this can be mental or physical.

The Not so ‘Sympathetic’ mechanisms

The physical aspect involves activation of the ‘Sympathetic’ nervous system, which basically protects us from harm, hence the name. But in doing so, it activates stress responses, which in the short and long run can cause a non-exhaustive list of ailments. For readers, a few examples of this response are highlighted.

The sympathetic nervous system comprises a vast meshwork of nerves that runs from the brain to basically every organ and niche of the body. It concerns the regulation of functions which are not under our control, such as digestion, bowel & bladder movements. However, it also equips us with functions to evade or cope with any form of stress, which is why the response it mounts is called the ‘Fight, Fright and Flight’ responses.

The downside of this response in the long run is that people who remain in a constant state of alertness/heightened stress have their sympathetic nervous system go into overdrive. This can lead to chronic metabolic diseases, increased susceptibility to infections, changes in body fat composition, and even melasma (pigmentation on the face).

HEART RATE VARIABILITY (HRV)

One mechanism that is increasingly being looked over in recent times is called HEART RATE VARIABILITY (HRV). In a nutshell, normally, our heart rate is variable from breath to breath, and there is physiological slowing or quickening of our heart. When this variation is lost, as in cases of continuous racing of the heart in anxiety, or maybe because of some contents (natural versus processed) of the food we eat, we are prone to all sorts of heart rhythm/function troubles.

Among other changes, high blood sugars and cholesterol, a very fast heart rate, and being finicky and fidgety most of the time stand out.  All the above, when persisting for a long time, can take a heavy toll on one’s health, eventually unmasking or producing metabolic diseases.

The Remedy!

It is imperative to try to mitigate the triggers for our negative feelings and seek help from Psychologists/Psychiatrists if needed. Stress, in the form of simple overthinking, depression, or post-traumatic stress disorder, should be picked up earlier by Physicians since early management could avoid a lifetime of disease burden. 

To improve HRV, regular deep-breathing exercises are effective, reducing sympathetic drive and allowing the parasympathetic (the opposite effect) to take over. It leads to more variability in heart rate and rhythm, and can terminate panic attacks as well (Yes! The breathe slow and deep routine). Regular exercise, both aerobic and high-intensity, when incorporated in our lives, can even simple walks prove to have antidepressant effects.

Lastly, the foods we eat determine the health of our gut and eventually our brain. Make sure you eat more natural, unprocessed foods, and maintain balance. More greens, balanced with different sources of meat, help.

In conclusion, mental and physical health go hand in hand. It’s high time we, as physicians and the common folk, started taking them as such and focused on our ‘well-being’ and holistic medicine rather than correcting and ‘repairing’ individual body parts.

Mosquito-Borne Diseases on the Rise: Protect Yourself This Summer

0

Along with longer days and warmer temperatures, summer heralds much more robust mosquito populations in South Asia, and specifically in Pakistan. Summer warmth accelerates the mosquito life cycle, meaning disease-carrying insects like dengue and malaria multiply rapidly.

In September 2022, Pakistan faced the worst flood in its history, when two-thirds of its territory was submerged in floodwater. Amin Jan, a young volunteer from Nowshera, was closely observing the devastating situation. After the flood was over, he joined a campaign aimed at providing rations to affected people.

He actively participated in distributing food, medicines, and clean drinking water. One day, during food distribution, he saw a mosquito biting his hand. He immediately swatted the mosquito. However, it was too late for him to restrict the entry of an uninvited guest brought by the insect bite.

Read about the 2022 devastating Flood in Pakistan: After the floods come disease: IDP camps in flood-hit Pakistan.

The very next day, Amin Jan experienced a rise in his body temperature. As he went to the doctor, a diagnosis was made of an infection with the dengue virus. A never-ending high fever, sweats, and nausea kept him in discomfort for the following 18 days.

Being barely able to eat, drink, or move, he survived at the expense of losing his body energy. For a long period of time, he was unable to perform his normal daily activities. At the same time, about 45 people from his city lost the battle of life against the dengue virus.

Since 2000, around two million people have died every year due to mosquito bites. Mosquitoes have killed more individuals than any other cause of death over the course of human history, making them the deadliest animal species in the world.

Mosquito Surge in Pakistan

These tiny creatures carry multiple viruses that are fatal to human health. An infected female mosquito can inject viruses into our body during blood feeding. These infections can lead to mild to life-threatening sickness.

Pakistan, like other subtropical countries, offers favorable conditions for mosquito breeding. Their expansion across the country has brought a variety of viruses in recent times. Among these, the dengue virus, the causative agent of dengue fever, has been well established in other provinces of Pakistan since it first appeared in 1994 in Karachi.

Dengue has been recorded in all provinces of the country. According to the National Institutes of Health, 22,938 and 48,906 dengue cases were reported in 2017 and 2021, respectively. In 2022, 41,746 confirmed dengue cases were reported mainly in Sindh Province. In the previous year, 103 people lost their lives in Sindh due to mosquito-borne diseases.

Other mosquito-borne viruses: Chikungunya, West Nile, Japanese encephalitis, and Zika, have been confirmed to be circulating in different parts of Pakistan. Human infections due to these viruses have also been documented. While the Chikungunya virus causes severe joint pain, the Japanese encephalitis and Zika viruses mainly affect the human brain. Mortality rate due to Japanese encephalitis virus is as high as 20 to 30%.

Experts from the World Health Organization and the Centers for Disease Control and Prevention suggest that the prevention of mosquito bites is the primary defense strategy for combating these diseases. The potential danger of outbreaks due to these viruses exists in many regions of the country, which warrants early preparedness.

The surge in mosquito emergence and expansion is attributed to many factors, including but not limited to climate change and unplanned urbanization. Historically, many mosquito-borne disease outbreaks in Pakistan have been reported after catastrophic floods in  2010-2012, 2022, and 2025. As soon as the flood disappears, stagnant water bodies accumulate, helping mosquito breeding, which contributes to its expansion.

According to a report of the United Nations, in 2011, more than 12,000 cases of dengue fever and 125 deaths were linked to the disease across Pakistan, with the majority occurring in Punjab province. Here is a story by Sara Zaman from the Voice of America that reflects on the situation after the flood: Flood Victims in Pakistan Face Threat of Diseases

Currently, Pakistan is among the top five nations worldwide with a rising population. Here, a growing number of people are shifting to urban life. Major cities like Karachi, Lahore, and Peshawar are seriously affected by environmental pollution. In addition, multiple-story buildings and the trade of used tires are increasing the mosquito population.

Warm temperatures, around 26-29 °C, and water are the leading components for their survival. Keeping water uncovered in tanks, pots, or other similar containers is an ideal habitat for mosquitoes to lay eggs. A few developmental stages transform eggs into adults.

Symptoms, Treatments, and Prevention!

Although diseases caused by mosquito-borne viruses can have a variety of symptoms depending on the virus and its infection duration, common symptoms include headache, fever or chills, muscle and joint pain, nausea or vomiting, rashes, and pain behind the eyes. Other symptoms may include abdominal pain, tiredness, and loss of appetite.

Despite extensive ongoing research in this area, infections due to these viruses lack adequate treatment. Supportive care can help reduce complications. Avoiding mosquito bites is the key strategy for preventing infections. The use of mosquito nets, repellents, and smoke coils is extremely helpful in this regard. In addition, covering stagnant water can reduce their fast breeding.

Vaccination is another great way to avoid these infections. However, the unavailability of vaccines for these viruses is a growing challenge worldwide. With a few licensed vaccines, such as those for the Japanese encephalitis virus, Pakistan lacks most of them.

Way forward

“The rapid spread of dengue and other arboviral diseases in recent years is an alarming trend that demands a coordinated response across sectors and across borders,” says Dr Tedros Adhanom Ghebreyesus, WHO Director-General.

To achieve this goal, it is important to educate people about mosquito-borne diseases and how to control them. Educational settings need to provide training to protect from these predators. As such, applying insect repellents, wearing protective outfits, and destroying mosquito breeding habitats around our surroundings are the best practices. Nevertheless, it is imperative to establish well-equipped research facilities for tracking mosquitoes for the presence of viruses ahead of any outbreak.

Altogether, community awareness, mosquito control, waste management, surveillance, and advanced research facilities can contribute to developing a better strategy to save us from these viruses this summar.

Betelgeuse Supernova Can Outshine an Entire Galaxy

Betelgeuse is the second brightest star in the constellation Orion, marking the eastern shoulder of the hunter. Its name is derived from the Arabic term ‘bat al-jawzāʾ’, which means “the giant’s shoulder.” Betelgeuse is one of the most luminous stars in the night sky. It is a variable star and can be easily seen with the human eye in the night sky from Earth. With a telescope, it looks like a hunter carrying a gun on his shoulder. This is why astronomers also call it the ‘Armpit of a Giant’.

Why is Betelgeuse Called a Variable Star?

It is a variable star and usually has an apparent magnitude of about 0.6. However, in late 2019, it started dimming and reached an apparent magnitude of 1.6 by early 2020. It returned to its original brightness later that year. This “Great Dimming” was caused by a giant ejection of gas that condensed into dust when it cooled. Betelgeuse is easily discernible to even the casual observer, not only because of its brightness and position in the brilliant Orion but also because of its deep reddish colour. The star is approximately 548 light-years from Earth.

Dr Fazeel Mahmood Khan holds a PhD from the Max Planck Research School for Astronomy and Cosmic Physics at the University of Heidelberg, Germany, and is currently a researcher at New York University in Abu Dhabi, United Arab Emirates. Speaking to Scientia, Dr Fazeel Mahmood Khan said that Betelgeuse belongs to a group of variable stars, and their light changes after a certain period due to internal physical processes.

He said that the light of the giant star Betelgeuse varies in a regular cycle. A typical physical cycle lasts 2170 days. During this time, the light of this giant star dims and then automatically returns. Interestingly, these variations in light are caused by vibrations in the outer layers of this star.

According to Dr Mahmood, the mass of Betelgeuse is barely 15 times that of the sun in our solar system, and its astronomical lifespan is only 10 million years, which is much shorter than our sun’s lifespan of 10 billion years. That is why this star is now nearing its end.

When will it Explode?

Astronomers believe that Betelgeuse will explode as a supernova soon, and the process of a star becoming a supernova is extremely powerful. Scientists believe that when Betlegeuse explodes as a supernova, it will be so bright that it will outshine an entire galaxy full of billions of stars.”

Astronomers still do not know for sure when Betelgeuse will explode as a supernova. “We may be able to see this very unique scene in our lifetime, or it is also possible that our future generations will witness its explosion,” Dr Mahmood adds.

Betelgeuse’ Great Dimming

The star Betelgeuse has been the focus of astronomers’ attention for the past five years. In late 2019, a significant decrease in its brightness was noted, which had recovered by June 2020. Several explanations had been put forward for Betelgeuse’s dimming during this period.

The most plausible explanation is that a dust cloud formed near this star. According to Dr Mahmood, this explanation is also confirmed by data obtained from Hubble and several other telescopes. These telescopes also observed the “dimming” of the star, or the process of its light becoming dimmer. This theory states that Betelgeuse then ejected a large amount of material from its outer layers. This material then cooled down and condensed into a dust cloud, which partially blocked the star’s light from reaching Earth.

According to astrophysicists, Betelgeuse is a massive red star that is constantly pulsating due to its internal temperature, pressure, and unstable outer layers. This process causes the star to expand and contract, causing its light to dim or brighten during specific periods.

Why is the Process of Supernova Making Important?

Dr Fazeel Mahmood Khan explains that when Betelgeuse explodes into a supernova, it will appear brighter in the sky than Earth’s full moon. “It will probably be visible in daylight for weeks or months”. The process of stars becoming supernovae is of utmost importance in the universe. When a star explodes, it creates large quantities of crucial elements in the form of nuclear reactions, which are scattered everywhere with the explosion. These elements include iron, oxygen, nickel, silicon, sulfur, carbon, nitrogen, and uranium, etc.

‘All these elements except hydrogen and helium were actually created through this process. “Even the elements in the Earth and our bodies were formed inside stars, which were later scattered everywhere when these stars exploded and became supernovae. If we look far back in the physical history of the universe, the emergence of human existence was actually made possible only because of “stardust.”

Dr Mahmood concludes that, “Sooner or later, the outer layer of Betelgeuse will burst, turning it into a black hole, and that will mark the final chapter in the astronomical life cycle of this massive star.”

Exploring Anatolian Archaeology with Dr Thomas Zimmerman: Science, Metals, and Ancient Civilizations

Archaeologist and archaeometallurgy specialist Dr. Thomas Zimmermann has spent decades researching the ancient cultures of Anatolia and has extensive excavation experience across Türkiye. Currently an Associate Professor at Bilkent University, his work combines traditional archaeology with advanced scientific analysis to investigate how ancient communities adapted, innovated, and transformed over time. In this interview with Scientia Pakistan, he reflects on his journey into Anatolian archaeology, the scientific techniques reshaping the field, and what the ancient world can still teach us about resilience and human society today.

Watch the complete interview on our YouTube Channel: Exploring the rich “Anatolian Archaeology” with Dr Thomas Zimmerman – Bilkent University.

Maham: What inspired you to study Archaeology and work on Anatolian Archaeology?

Dr Zimmerman: Two reasons drew me to archaeology. One was rather trivial: the Indiana Jones films. Although Indiana Jones has little to do with professional archaeology, I was fascinated by the idea of combining teaching and research with adventures in distant places.

The second reason was more influential. While I was doing sports archery in high school, one of the club members, a local archaeologist, invited me to join an excavation. It was a rescue dig in Bavaria in the 1990s, investigating the remains of an early Neolithic village from the 6th millennium BC. For many of the archaeologists involved, it was just another Neolithic site. For me, however, it was a revelation. That experience convinced me to study archaeology.

My path to Anatolian archaeology came later. I began my studies at the University of Regensburg, where the focus was primarily on the archaeology of Bavaria and Central Europe. That changed when a new professor, Andreas Müller-Karpe, joined the department and introduced us to Anatolian archaeology. In 1996, he took me to my first excavation in Turkey, in Eastern Cappadocia near Sivas.

The site was later identified as a Hittite provincial town, and cuneiform tablets helped confirm its name as Sarissa. That experience sparked my interest in Anatolian archaeology, and I decided to pursue it as my specialization. At the same time, my training in European archaeology proved valuable. It gave me expertise in both European and Anatolian archaeology, a combination that later helped me secure my position at Bilkent University.

Maham: Türkiye sits at the crossroads of major ancient civilizations. How has this unique geographic position shaped the archaeological record of Anatolia?

Dr Zimmerman: Anatolia is often described as a bridge between East and West, the Orient and the Occident. However, that description can be misleading because it suggests a passive role. Anatolia was not simply a corridor through which ideas and technologies passed; it was also a center of innovation in its own right.

One example is early metallurgy. Experimental work with copper began here remarkably early, long before similar developments appeared elsewhere. While this was not yet true smelting, the earliest evidence for working and shaping copper dates back to the ninth and even tenth millennium BC.

Anatolia also preserves some of the most important evidence for the beginnings of the Neolithic period. Sites such as Göbekli Tepe, Karahan Tepe, and Sayburç reveal complex and still puzzling developments that took place around 12,000 years ago, at the onset of the Holocene and the earliest Neolithic.

At the same time, Anatolia’s location connected it to many dynamic regions, including Mesopotamia, the Aegean, the Mediterranean, the Caucasus, and the Black Sea. These connections encouraged the exchange of ideas, technologies, and cultural practices, making the region a unique meeting point for different societies.

Moreover, Anatolia was one of the key regions where people first experimented with sedentary life. Around 12,000 years ago, communities here began testing a new and uncertain way of living that would ultimately transform human history.

Maham: Your expertise is also in metallurgy. What can metals tell us about ancient societies?

Dr Zimmerman: Metals are important because they reveal how ancient societies organized technology, trade, resources, and power. They were a major driver of long-distance exchange and economic development, much as they are today.

Anatolia is one of the most mineral-rich regions in the world, with many easily accessible copper deposits. People began experimenting with copper very early, initially using minerals such as malachite (oxidized version of copper) as pigments and later shaping native copper through hammering and heating. These early activities were not yet true metallurgy, but they show a growing interest in manipulating metal.

The breakthrough came around 5000 BC with the appearance of the first cast copper objects, evidence of extractive metallurgy. Interestingly, some of the earliest examples appear in Anatolia. Yet after this initial development, metallurgy seems to fade from the archaeological record for roughly 1,500 years, even as metalworking flourished in parts of the Balkans and Central Europe. Why this happened remains one of the unresolved questions in the history of metallurgy.

Around 3500 BC, metallurgy re-emerged in Anatolia and expanded rapidly. During the Early Bronze Age, we see sophisticated alloying, casting, plating, soldering, and other advanced techniques. Famous examples include the treasures from Troy and the rich burial goods from Alacahöyük.

Metals also tell us about social change. From the third millennium BC onward, the archaeological record reveals increasingly visible social hierarchies. Elites controlled resources, production, and specialized knowledge, distinguishing themselves through wealth, prestige goods, and monumental residences. Even in the absence of written records, metal artifacts provide clear evidence for the emergence of complex societies and powerful ruling groups.

Maham: Modern archaeology now increasingly relies on scientific techniques such as X-ray fluorescence, archaeometry, and more. How have these methods transformed our understanding of the past?

Dr Zimmerman: Scientific analysis has indeed transformed archaeology very dramatically over the past half-century. The field has moved far beyond simply excavating, cataloguing, and displaying artifacts. Today, archaeology seeks to answer much broader questions: Who are we? How did human societies develop? How did communities, cities, and complex social systems emerge?

Archaeological science has been central to this shift. Take metallurgy as an example. A metal object may appear to be bronze, gold, or copper, but scientific analysis can reveal its exact composition and origin. This allows us to investigate where raw materials came from, how technologies developed, and how trade networks operated.

Techniques such as X-ray fluorescence and lead isotope analysis have been particularly valuable. They enable us to identify the sources of metals and reconstruct ancient exchange networks. At Troy, for example, metal artifacts from the third millennium BC appear similar in form, but scientific analyses show that the copper used to make them came from different regions over time. This reveals changes in trade and resource acquisition that would otherwise remain invisible.

So this, of course, triggers completely different questions we have to ask. And, this is only for metal work. Think about all the other techniques, like dating with radiocarbon or oxygen isotopes, thermal luminescence, and optical stimulated luminescence, which allow us to date siliceous substances. And the biggest game changer at the moment is, of course, genetics and ancient DNA, which presents us with a real avalanche of data we have to digest.

Maham: What parallels, if any, do you see between ancient societal transitions and the challenges modern societies face today?

Dr Zimmerman: There is a famous idea that history teaches us nothing, but in reality, studying ancient societies can provide valuable insights into how humans respond to crises.

Let me give you an example from the late second millennium BC, again, focusing on Anatolia. Here we have what we call the collapse of the ancient Mediterranean civilization. So the Hittites, the Mycenaeans, the Egyptian Pharaonic kingdom, the Assyrian kingdom, they seem to have been wiped off the map and collapsed, which is not really true. We see that life is continuing. There’s a transformation going on, for sure.

But it’s much more complex than we thought. And one of the triggers here, which is still vividly debated, is climate change. It’s what we call an RCC, Rapid Climate Change, at the end of the second millennium, a kind of wiggle we see in the chart, which eventually affected also larger regions here. And what we see are also migration waves, possibly triggered by climate change. There is evidence for population movements from Europe into the Balkans and Anatolia, though this is only part of a much larger and still debated picture.

A similar debate exists for the so-called 4.2-kiloyear event around the end of the third millennium BC, a period of climatic stress lasting several centuries. Its impact varied widely by region and is sometimes linked to disruptions in states such as the Assyrian kingdom, though the relationship is still contested.

What the archaeological record shows clearly is that there was no uniform collapse. Some regions experienced severe drought and hardship, while others adapted successfully or even flourished. Communities responded in different ways: by developing new water management systems, building infrastructure, or shifting settlement strategies. So the lesson we learned from the archaeological research, focusing on this particular period, is that human communities are very resilient and also very inventive. This diversity of response is perhaps the most relevant parallel for understanding how modern societies might deal with large-scale challenges today.

Maham: Having worked on multiple excavation projects across Turkey, what has been one particularly memorable or surprising discovery from your fieldwork?

Dr Zimmerman: That’s a difficult question, because every excavation or laboratory project can produce unexpected and exciting results. One of my most memorable experiences was related to metal analysis.

We were working on material from several sites, including Kinet Höyük, a harbour settlement in Cilicia on the eastern Mediterranean. There had long been a suspicion that the Hittites had taken control of the site at some point and used it as a strategic maritime hub, based on pottery, seal impressions, and other indirect evidence. In the laboratory, we were conducting bulk analysis of metal objects using X-ray fluorescence. From a secure second-millennium BC context, we identified a group of artefacts with a very unusual chemical signature. They were arsenical copper alloys or bronze, but consistently showed a very high nickel content.

It turned out that this metal came from a highly specific source that was exploited during the Hittite imperial period and likely controlled by central authorities. It appears to have been a restricted supply of copper from a particular nickel-rich deposit. We know similar material from Hattusa, the Hittite capital, so finding it at Kinet Höyük was particularly significant. It suggests that the site was, at least for a short period, supplied with this exotic and peculiar raw material, which is copper, with a very high nickel content, through centralized control. That was quite fascinating.

Myths vs. Facts: Civilizations, Secrets, and the Stories We Choose to Believe

There is always something irresistible about ruins. A broken wall, a weathered carving, a city buried under sand each invites not only inquiry, but subtle imagination. Over time, that imagination hardens into myths, spreading its roots far across multiple dimensions of history. The result, however, is always a curious blend of fact and fiction, in which ancient civilizations are attributed to lost continents, extraterrestrial visitors, or catastrophic mysteries rather than human ingenuity.

In an age of viral narratives and cinematic history, archaeology quietly competes with myth-making. This feature examines some of the most persistent myths surrounding the world’s iconic archaeological sites, placing them against evidence, data, and scholarly consensus.

When History Becomes Legend!

Rising from the golden sands of ancient Egypt, the Great Pyramid of Giza continues to stand as the last breathing wonder of the ancient world, inspiring awe and speculation in equal measure. For years, myths have circulated suggesting that this monumental structure was built by aliens or a mysterious lost civilization possessing unimaginable technology. However, archaeological discoveries tell a very different and deeply human story.

Evidence uncovered by researchers, including remains of worker settlements, tools, and written records, confirms that the pyramid was constructed around 2600 BCE during Egypt’s Fourth Dynasty. Far from being built by slaves or supernatural beings, it was the result of a highly organized workforce of approximately 20,000 to 30,000 laborers. These workers, operating in carefully managed rotating shifts, demonstrated remarkable engineering skill and coordination.

Other than the pyramid itself, modern Egyptologists also claim multiple discoveries around the region. Researchers say that their latest round of imaging may have uncovered two massive finds, including an ancient mega structure and a second Sphinx. If true, this will change everything we thought we knew about the region

Filippo Biondi, one of the radar engineers responsible for the find, appeared on the Matt Beall Limitless podcast, where he shared the exciting news, saying that he was “very confident” about his findings, adding that he was about “80 percent” sure that the massive structure he found would turn out to be a second version of the iconic structure. 2 

The Great Pyramid thus stands not as a relic of myth, but as a powerful testament to human ingenuity, discipline, and collective effort. When most people picture Egyptian pyramids, they imagine gold treasures and mummy-filled chambers straight out of an adventure movie. The reality turns out to be far more bizarre, narrated by Adam Garcia. 1

The City of Petra, capturing Historians and Travelers Over Centuries.

Carved into rose-red cliffs and hidden within rugged desert mountains, the ancient city of Petra has long captured the imagination of travelers and historians alike. Popular myth often portrays Petra as a “lost city” only recently discovered in modern times, which is shrouded in mystery and secrecy. In reality, this remarkable site was never truly lost. It remained well known to local Bedouin communities for centuries before it was introduced to Western audiences in the 19th century. Historical and archaeological evidence reveal that Petra once flourished as the thriving capital of the Nabataean Kingdom between approximately 300 BCE and 100 CE.

Strategically positioned, this city controlled major caravan routes, making it a vital center of trade connecting Arabia, Egypt, and the Mediterranean world. Rather than a forgotten wonder suddenly unearthed, Petra stands as a testament to a sophisticated and enduring civilization whose legacy was preserved by those who lived closest to it.

Abraham Mashaleh, 48, a Jordanian native born and raised in Petra who has worked as a guide to the ancient city for over 20 years. He pointed at the narrow passage after a kilometer-long trail through rose-red  “siq,” or winding rock gorges soaring over 100 metres up into the sky. With a high and wide facade, the monastery, or Ad Deir in Arabic, revealed itself as the valley slowly opened up. 

The grand monument was the tomb of a Nabataean King, which was carved out of the rock, and represents the genius of the engineering skills of the ancient people, according to Mashaleh. Its exotic landscape, which is authentically ancient, has often seen Petra being used in Hollywood’s cinematic productions for decades. 4

myths
Scholars widely interpret these accounts not as factual records, but as philosophical allegories which are merely crafted narratives intended to illustrate ideas about ideal societies, moral decay, and divine justice.

The Legendary City of Atlastis

Few legends have endured as powerfully or as persistently as that of the city of Atlantis, often imagined as a technologically advanced island civilization that vanished beneath the ocean in a single catastrophic night. Popular culture continues to revive the tale, presenting Atlantis as a lost utopia whose secrets remain hidden beneath the turbulent currents of water. 

However, historical scrutiny offers a far more grounded perspective. The only primary reference to Atlantis appears in the works of the ancient Greek philosopher Plato, who described it in his dialogues Timaeus and Critias. Scholars widely interpret these accounts not as factual records, but as philosophical allegories which are merely crafted narratives intended to illustrate ideas about ideal societies, moral decay, and divine justice.

Many believe that the Atlanteans were not just intellectually superior but technologically advanced as well. Many historians are of the view that the city possessed futuristic technology, often citing evidence from Edgar Cayce, an American clairvoyant, who claimed that Atlanteans used crystals for energy production. While intriguing, no sound archaeological evidence or historical text supports this claim. 

Another idea that the mythical city lies within the infamous Bermuda Triangle has often been romanticized in literature and films. Despite the allure, no verifiable proof links the geographic anomalies in the Bermuda Triangle to the lost city. Moreover, the location contradicts Plato’s description of Atlantis as being beyond the “Pillars of Hercules.” 6

Following the real perspective, despite centuries of exploration and speculation, no credible archaeological evidence has ever been found to confirm the existence of such a civilization. As a result, Atlantis remains less a chapter of human history and more a reflection of human imagination; an enduring story shaped by philosophy, curiosity, and the timeless allure of the unknown.

The widely held myths suggest that the Maya vanished suddenly and mysteriously, leaving their cities abandoned without explanation.

The Majestic Ruins of Chichén Itzá

Towering above the Yucatán Peninsula, the majestic ruins of Chichén Itzá stand as a powerful symbol of the brilliance of the ancient Maya civilization, yet they are often surrounded by persistent misconceptions. A widely held myth suggests that the Maya vanished suddenly and mysteriously, leaving their cities abandoned without explanation.

In reality, historians and archaeologists describe a far more complex and gradual process. The so-called “collapse” of Maya city-states between 800 and 900 CE was not a single catastrophic event, but a region-specific decline driven by a series of events related to environmental stress, prolonged droughts, warfare, and political fragmentation. Far from disappearing, millions of Maya descendants continue to live across Central America today, preserving their rich cultural heritage. At the heart of Chichén Itzá lies the flat-topped, iconic pyramid known as El Castillo, an architectural masterpiece that reflects the scientific sophistication of its builders. 

During the equinoxes, the play of light and shadow along its steps creates the striking illusion of a serpent descending the pyramid, an effect carefully engineered through precise astronomical alignment. This phenomenon is not evidence of mysticism, but rather a testament to the advanced knowledge and ingenuity of the Maya people. 8

Myths Previaling Mohenjo-Daro and Taxila

Often overshadowed in global historical discourse, Pakistan’s archaeological heritage continues to reveal some of the earliest and most sophisticated chapters of human civilization, challenging long-held myths with evidence-based research. One of the most remarkable examples is Mohenjo-Daro, an ancient urban settlement situated in the southern province of Sindh. Frequently the subject of sensational claims, the site has been wrongly associated with the myth of destruction by an ancient nuclear explosion. 

However, archaeologists and historians firmly reject this notion, citing the complete absence of radiation or other scientific evidence to support it. Instead, extensive excavations at Mohenjo-Daro paint a far more grounded and compelling picture of gradual decline rather than sudden catastrophe. Believed to be one of the principal cities of the Indus Valley Civilization, the settlement flourished around 2500 BCE with advanced urban planning, including well-organized streets, sophisticated drainage systems, and standardized construction techniques. 

By approximately 1900 BCE, however, evidence suggests that the city began to lose its vitality due to a combination of environmental and economic factors. Shifting river patterns, particularly changes in the course of the Indus River, likely disrupted water supply and agricultural stability. At the same time, declining trade networks and broader climatic changes may have further contributed to the gradual abandonment of the city.

Today, Mohenjo-Daro stands not only as a testament to human ingenuity but also as a reminder of how civilizations are shaped and sometimes totally undone by natural forces rather than dramatic myths. As researchers continue to study the site, it reinforces Pakistan’s vital role in the story of early human development, urging the global community to look beyond misconceptions and appreciate the region’s profound historical significance.

Amid growing public fascination with ancient mysteries, experts are pushing back against sensational claims surrounding Mohenjo-Daro, one of the cities of the Indus Valley Civilization. Popular myths have long suggested that the city was destroyed by an ancient atomic explosion or abruptly abandoned overnight, with residents mysteriously vanishing. However, archaeologists firmly dismiss these narratives, emphasizing that there is no scientific evidence, such as radiation, blast damage, or vitrified structures, to support the idea of a catastrophic explosion. Instead, research points to a gradual decline beginning around 1900 BCE, driven by environmental changes, shifting river systems, and weakening trade networks.

Similarly, the notion of a sudden mass disappearance has been contradicted by excavation data, which reveals multiple layers of habitation, indicating that residents slowly adapted to changing conditions and eventually migrated over time. Experts stress that the true story of Mohenjo-Daro lies not in dramatic myths, but in the complex interplay of natural and economic factors that shaped its rise and fall. 10

In the ancient landscape of South Asia, the historic city of Taxila stands as a powerful reminder that civilizations are rarely simple or one-dimensional. Often described merely as a Buddhist religious center, Taxila’s true story reveals a vibrant and multicultural city that flourished as a crossroads of trade, education, and diverse cultural influences for nearly a thousand years.

Archaeological discoveries show that Taxila was far more than a place of worship, recognized globally. From around 600 BCE to 500 CE, the city evolved into one of the most important urban centers of the ancient world. Situated at the heart of a strategic location connecting Central Asia, South Asia, and the Middle East, Taxila attracted merchants, scholars, pilgrims, travelers, and rulers from different civilizations.

Perhaps Taxila‘s most enduring legacy is its reputation as a great center of learning. The Taxila University, which flourished between the 5th century BCE and the 2nd century CE, was one of the world‘s earliest institutions of higher education. Students from across Asia flocked to Taxila to study a wide range of subjects, including the Vedas, mathematics, medicine, politics, warfare, astronomy, and philosophy.

Famous alumni of Taxila include Chanakya (c. 4th century BCE), the brilliant strategist and adviser to Chandragupta Maurya, and Charaka (c. 3rd century BCE), the father of Ayurvedic medicine whose treatise, the Charaka Samhita, is still widely studied today. Taxila‘s influence on ancient scholarship was immense, with its ideas spreading across the Silk Roads to influence thinkers in distant lands. 12

The city first came under the influence of the powerful Achaemenid Empire, which introduced administrative systems and cultural exchanges. Later, after the campaigns of Alexander the Great, Greek influence reached Taxila, bringing new artistic styles, architecture, and philosophical ideas. These interactions helped shape the unique identity of the region, which can be seen today in all the remnant sites of early dwellers in Taxila.

During the reign of the Kushan Empire, Taxila reached new heights of prosperity. It became an important center for commerce and learning, attracting students from distant lands. Historians often regard Taxila as one of the earliest hubs of higher education, where subjects such as philosophy, medicine, politics, astronomy, and military science were studied.

The city also witnessed the influence of the Gupta Empire, adding another cultural layer to its already rich heritage. Temples, monasteries, markets, and residential settlements coexisted, reflecting a society shaped by multiple traditions rather than a single religious identity.

Today, Taxila challenges the myth of being solely a Buddhist site. Instead, it represents a remarkable meeting point of civilizations, a place where Persian governance, Greek thought, Central Asian trade, and South Asian scholarship blended into a thriving urban culture. Its ruins continue to tell a story not just of religion, but of human connection, intellectual growth, and cultural harmony across centuries.

Mesopotamia

In the heart of the ancient Middle East, the fertile lands between the mighty Tigris River and Euphrates River gave rise to one of humanity’s greatest achievements, the birth of organized urban life known as Mesopotamia. This region laid the foundation for cities, governance, agriculture, and written communication long before the construction of monumental pyramids.

Stretching across much of modern-day Iraq and parts of Iran, Mesopotamia is often remembered through myths and legends. Yet archaeologists say its true history is even more extraordinary, revealing a slow and steady human transformation rather than a sudden appearance of civilization.

At the center of this development stood the Sumerian Civilization, which flourished between approximately 4000 and 1900 BCE. The Sumerians are credited with creating some of the world’s earliest cities, including bustling settlements built around fertile farmland and complex irrigation systems.

Contrary to the long-standing myth that civilization emerged suddenly in Mesopotamia, archaeological evidence paints a different picture. Layers of excavation reveal that urban life evolved gradually from earlier communities such as the Ubaid Culture and the Samarra Culture. These early societies developed farming techniques, water management systems, and permanent settlements that slowly transformed into organized cities.

Experts believe that irrigation played a decisive role in this transition. By controlling river water and directing it toward agricultural fields, ancient communities produced food surpluses that supported growing populations. As villages expanded, specialized labor emerged, allowing people to focus on crafts, trade, administration, and religious practices.

The rise of Mesopotamian cities marked a turning point in human history. Temples became centers of authority, marketplaces encouraged trade, and written records began to appear for managing resources and communication. These innovations helped shape the structure of later civilizations across the world.

Today, the story of Mesopotamia stands not as a mysterious beginning but as a testament to gradual human ingenuity. Its legacy reminds historians that civilization was not born overnight; it was built step by step through innovation, cooperation, and adaptation to the environment.

In Sumerian Civilization beliefs, the afterlife was seen as a dark place called Kur, where all souls went after death. They believed that people lived a shadowy existence there, no matter how good or bad they had been in life. One famous story about the descent of a goddess into the underworld ruled by her sister symbolized death, struggle, and renewal in nature and human life.

From an Islamic perspective, these were ancient human beliefs and myths created before divine guidance was fully preserved through later prophets. Islam teaches a different understanding of life after death, where death is not the end but the beginning of the Hereafter. Every soul enters a stage called Barzakh after death. People are judged by Allah according to their deeds; good deeds lead toward Paradise, while evil deeds can lead to punishment.

Unlike Sumerian beliefs, where all souls shared the same fate, Islam emphasizes justice, reward, and accountability. The Qur’an explains that every person’s actions matter and no deeds are ignored. Death held great importance in Sumerian society as well. Their rituals, mourning practices, and burial customs reflected respect for the dead and fear of the unknown afterlife. This shows that even ancient civilizations deeply questioned what happens after death and tried to understand humanity’s spiritual journey. 14

AI’s Thirst for Water: The Environmental Impact We Should Know!

0

Every time you ask an AI a question, somewhere on Earth, water evaporates. Not metaphorically — literally. This is the story of how the intelligence we are building is quietly draining the planet’s most precious resource, and the science of what we can do about it.

A Question Nobody Was Asking!

People often debate the environmental cost of AI, and carbon emissions usually dominate the conversation. But there is a quieter crisis running alongside it — one that threatens something more immediately essential to human life: fresh water. Only 3% of Earth’s water is freshwater. Of that, a mere 0.5% is accessible and safe for human use. That thin sliver is what billions of people, farms, and ecosystems depend on entirely, and increasingly, it is what keeps AI running.

The Controversy: Silicon Is Thirsty

The numbers, when you sit with them, are staggering. A single large data center can consume up to 5 million gallons of water per day — roughly the daily water use of a town with 10,000 to 50,000 residents. Google reported using over 5 billion gallons of water across all its data centers in 2023, with nearly a third drawn from watersheds already experiencing water scarcity. A University of California, Riverside study estimated that around 20 AI queries consume water equivalent to a small bottle of drinking water.

What makes this a controversy, rather than simply an engineering challenge, is a combination of choices that many find hard to justify.

The Location Problem: The majority of new AI data centers built in the United States since 2022 have been located in regions already grappling with high water stress — Arizona, Texas, where aquifers are shrinking, and drought conditions are worsening. OpenAI’s $100 billion Stargate AI infrastructure project is being anchored in Abilene, Texas, a city where local hydrologists describe a “water-energy nexus crisis.” Water has historically been treated as an afterthought in data center siting decisions because, compared to land and electricity, it is cheap.

The Transparency Problem: Many companies are less than forthcoming about how much water their facilities use. A 2021 survey found that only 51% of data center operators tracked their water usage at all — and just 10% tracked it across all their facilities.

The Evaporation Problem: Approximately 80% of the fresh water withdrawn by data centers evaporates during the cooling process. It does not become wastewater that can be treated and returned. It simply vanishes into the atmosphere — gone from local water systems permanently.

The Science: Why Do Computers Need So Much Water?

When electricity flows through a conductor, some of that energy is converted into heat — a phenomenon described by Joule’s Law. Modern AI processors, particularly the GPUs used to train and run large language models, push enormous amounts of current through extremely dense arrangements of transistors. The result is intense, concentrated heat that must be continuously removed or the chips will throttle, degrade, and ultimately fail.

The traditional solution — still dominant in roughly 95% of the world’s data centers — is evaporative cooling. Industrial cooling towers spray water over large surface areas, where it evaporates and carries heat away. It is effective, relatively inexpensive, and consumes massive volumes of fresh water in the process. Approximately 60% of total data center water consumption is actually indirect, originating from the fossil fuel power plants supplying their electricity, not from on-site cooling alone.

The Next Frontier: When You Dip Electronics in “Water”

You may have seen videos of circuit boards submerged in liquid, running perfectly. This is not water — contact with live electronics would cause immediate short circuits and component failure. What those boards are submerged in is a dielectric fluid: a liquid engineered to be electrically non-conductive while being an excellent conductor of heat.

This technology, known as immersion cooling, submerges electronics in a bath of dielectric fluid. The fluid absorbs heat directly from the surface of chips and carries it to a heat exchanger, where it is cooled and recirculated. The same volume of dielectric fluid can absorb approximately 1,500 times more heat than the same volume of air.

Single-phase immersion cooling uses hydrocarbon-based mineral oils or synthetic esters. The fluid absorbs heat and remains liquid throughout, circulating through a heat exchanger in a continuous loop. Two-phase immersion cooling uses engineered fluorocarbon-based fluids with deliberately low boiling points. As chips generate heat, the fluid literally boils, transitions to vapor, rises, condenses on a cooled surface, and drips back down as liquid. This passive thermodynamic cycle requires no pumps and can handle heat fluxes exceeding 40 watts per square centimetre.

Unlike fresh water, dielectric fluid is not drawn from rivers or aquifers. Mineral oil comes from crude oil refining. Fluorocarbon-based fluids are synthesised by fluorinating hydrocarbon compounds. Synthetic esters, the most environmentally benign option, are derived from vegetable oils through esterification. None involves fresh water as a raw material, which is precisely the point.

So, Why Isn’t Everyone Doing This?

Immersion cooling setups cost three to four times more than traditional air or evaporative cooling infrastructure upfront. Existing servers are not designed to be submerged — fans must be removed, components need compatibility verification, and power supplies require modification. The entire data center layout must be rethought around liquid-filled tanks. There are also no universally adopted industry standards yet.

There is also a complication with the most advanced fluids. Fluorocarbon-based dielectrics contain PFAS — per- and polyfluoroalkyl substances, sometimes called “forever chemicals” — because they do not break down in the natural environment. The European Union has been moving to restrict several PFAS compounds, and 3M has announced it would phase out Novec production. The industry is working on PFAS-free alternatives using biodegradable synthetic esters, but mainstream adoption will take time.

The Incomplete Solution: Why the Water Crisis Remains

Even if every data center in the world switched to immersion cooling tomorrow, the water crisis would not be fully resolved. Data centers draw from regional electrical grids substantially powered by thermal generation, gas turbines, coal plants, and nuclear reactors — all of which require large volumes of cooling water. Immersion cooling can eliminate on-site evaporative losses while the power generation side of the problem persists as long as the grid remains fossil-fuel dependent.

The real solution is a combination: immersion or closed-loop cooling to eliminate on-site waste, paired with a transition to renewable energy sources, solar and wind, which require virtually no operational water, to address the indirect footprint. Countries like Iceland and Norway, which power data centers almost entirely with geothermal and hydroelectric energy in naturally cold climates, demonstrate what this combination can look like at scale.

The Bottom Line!

There is something quietly paradoxical about the AI revolution. We are building systems of extraordinary intelligence that, at their physical foundation, require some of the most basic things on Earth: electricity, land, and water.

The path forward is not to stop building AI, nor to pretend the environmental costs do not exist. Dielectric immersion cooling is not a magic solution, but it is a real one, grounded in solid thermodynamics. Its wider adoption, combined with a cleaner grid and genuine corporate transparency, represents the clearest technical pathway toward AI infrastructure that does not compete with human beings for the water they need to survive. The next time you send a query to an AI, somewhere, cooling equipment hums. Whether what it costs the planet is necessary and proportionate is, increasingly, a question that cannot be deferred.

The AI Nuclear Renaissance: How Diablo Canyon Became the Backbone of California’s Power Boom

AI-Powered Cancer Detection Is Changing Modern Medicine

A young mother of two lost her life after a grueling battle with the menace called ‘cancer.’ Early detection would have given her a second chance at life, but like many cancer patients, her cancer was detected far too late. This woman was Bethany Purvis, also known as the “Elsenham Bowel Warrior,” from Hertfordshire, England.

In 2014, she started noticing some changes in her bowel movements and experienced constipation and diarrhea with rectal bleeding. For almost two years, her symptoms were managed as if she had irritable bowel syndrome (IBS) and other minor conditions. Two years.

By the time a colonoscopy showed that she was suffering from stage three bowel cancer, the cancer had already spread to six of her lymph nodes. It was too late at this stage. Her cancer just wouldn’t stop, even with the surgery and all those rounds of chemotherapy. It eventually hit stage IV and metastasized to her lungs. She lost her five-year battle with bowel cancer in June 2021 and tragically passed away at the age of 42.

Cancer is one of the biggest killers across the world. The four most common types are breast, lung, bowel, and prostate cancers. As reported by the World Health Organization, the number of cancer cases is still rising across the world, and late-stage detection is a major reason it is claiming lives. Therefore, it goes without saying that Bethany’s case is not an outlier but a global archetype. 

The biggest problem with this ‘evil’ disease is that it is very hard to diagnose in its early stages because the symptoms are so vague that they can easily be confused with something benign. This is why scientists have started to turn to artificial intelligence as a solution in the fight against cancer to help doctors save as many lives as possible.

AI as a ‘Digital Second Opinion’

AI has the ability to review large amounts of data and pick up on patterns that are not visible to the human eye. In radiology, for example, AI software is referred to as a digital second opinion and alerts doctors to high-risk patients.

The medical community, for years, has wondered if AI would actually save lives or just generate more “false alarms.” The answer came in early 2026 with the completion of the Mammography Screening with Artificial Intelligence (MASAI) trial, which was the first randomized trial of its kind.

The study, headed by Dr. Kristina Lång of Lund University, found that AI-assisted screening detected 29% more cancers than the conventional method of having two radiologists review each scan. More importantly, it detected invisible cancers until they manifested as symptoms. This revolutionary finding proved that AI can decrease a radiologist’s workload by almost 44% without compromising safety and can effectively close the diagnostic gap that took Bethany’s life.

Diane thought it was just a stubborn cough

AI has already started producing life-saving outcomes for actual patients. In 2025, 60-year-old Diane from Glasgow came to her physician with what she thought was just a persistent cough. Her chest X-ray was analyzed by an AI algorithm called qXR, which drew the clinician’s attention to a possible lung nodule that might have been overlooked otherwise. 

Thanks to the AI’s ability to give her case priority in a matter of hours, she was expedited for a CT scan. The scan revealed that she had stage II lung cancer. It was through early detection that her case moved from potential delay to timely treatment and improved her survival chances.

Sheila almost walked away, reassured

In late 2024, a breast screening program was carried out at University Hospitals Sussex in West Sussex, United Kingdom. Over 12,000 mammograms that had been previously assessed as normal were reevaluated by an AI system named Mammography Intelligent Assessment (Mia). 

Sheila Tooth, a 68-year-old retired nurse from Littlehampton, West Sussex, was among the women whose mammograms were reassessed. It was discovered that she had early-stage non-invasive breast cancer that had not been detected during the first review. Since it was detected so early by the AI system, Sheila only required a lumpectomy. It is a type of breast-conserving surgery that involves the removal of a cancerous tumor or abnormal lump, as well as a margin of normal tissue surrounding it. She did not need any additional treatment and went back to her normal life. “It’s extraordinary, and I’m amazed. When I talk to friends, we just can’t believe this AI can detect what the human eye can’t always see. I just feel so lucky,” she said.

Biomarkers and Multiomics

In early 2026, research by MIT and Microsoft introduced CleaveNet, which is an AI model designed to develop molecular sensors for home diagnostic kits. These sensors can identify more than 30 forms of cancer by studying proteases, which are proteins that are overactive in the early stages of cancerous growth. This is not the only development in the field. There is also a move towards multi-omics, where AI combines information from various levels of biological systems:

Genomics is the study of DNA to look for particular mutations that suggest a high genetic risk of developing particular types of cancer. It tells us what might happen based on our genetic instruction manual. Proteomics, on the other hand, examines the proteins that are actually present in the bloodstream. As proteins are the workers of the cell, early changes or imbalances in certain proteins can be the first warning flag that a cancerous growth has begun. 

Transcriptomics is the bridge between the two. It watches as cells read their DNA. AI can identify the very first moments of a cell becoming cancerous, often before a tumor even develops. It does so by identifying this aberrant gene expression when a cell begins to read the wrong instructions.

AI is able to pick out a liquid biopsy pattern from a simple blood or urine test by combining all this complex information from different “omics.” This could potentially detect cancers like Bethany’s at Stage I when they are highly treatable. A liquid biopsy is a minimally invasive blood test that analyzes circulating tumor DNA and cells. This test offers a snapshot of a patient’s cancer and enables more precise monitoring and personalized treatment plans.

Limitations and Risk of Bias

It is important to remember that the quality of the AI’s output is solely dependent on the input that it receives. One of the biggest challenges that exists at present is the need for varied datasets so that the AI is not biased in its outputs. The objective remains the same regardless: to utilize better and more informed research to discover these new biomarkers and save lives through early detection.

Dr. Nadeem Riaz is a radiation oncologist at the Memorial Sloan Kettering Cancer Center, New York. He described how a lack of diversity in the training data can result in algorithms that work poorly for underrepresented populations. He warns:

“In oncology specifically, where cancer presentation and outcomes already vary significantly across populations, this bias could lead to missed diagnoses or inappropriate treatment recommendations.”  (Cancer Therapy Advisor, 2025).

Another important consideration is that the AI systems often suffer from a lack of portability when it comes to hospitals. Dr. Julian Hong, an assistant professor at the University of California, San Francisco (UCSF), notes that an AI system developed at a certain institution tends to fail when used in a different setting. (Cancer Therapy Advisor, 2025).

Although the benefits of AI in healthcare are numerous and quite promising, there are also some risks associated with it. If the data used to train the algorithms is not diverse, the algorithms may not perform well in different populations. Resource-scarce clinics may not be able to fully benefit from AI, and false positives can cause undue stress to patients in such cases.

Economic and Global Outlook

As of 2026, the AI cancer diagnostics market is valued at approximately $1.28 billion, and it is expected to double by 2035 (Towards Healthcare, 2026). However, the cost of care is not measured in dollars and cents. In developing countries, where the ratio of oncologists to patients is dangerously low, AI is being used as a triage assistant. A triage assistant is an AI system that automatically sorts and prioritizes patients based on the urgency of their symptoms. It also scans results and flags high-risk cases for immediate clinical review.

In January 2026, a global machine learning study published in the journal Annals of Oncology found that the biggest lever for improving cancer survival rates in many countries was not new drugs alone but greater access to pathology and universal health coverage. By offering high-level diagnostic intelligence through cloud-based AI, the equity gap for patients living in distant areas from major cancer centers is being bridged.

The Road Ahead!

To sum it all up, the objective is clear: a timely diagnosis can be the difference between life and death, and an untimely diagnosis can have a huge impact on patients as well as their families. AI can help by pointing out the weaknesses and flaws in the healthcare system and allowing doctors to make earlier diagnoses.

Technology by itself will not be the solution to the problem of untimely diagnoses, but when combined with careful analysis, AI can assist in bringing attention to areas where the systems are failing. In the fight against cancer, the diagnostic gap could be as important as the whole discovery.

Even with the optimism of 2026, the handshake between AI and medicine is not without its challenges and faces significant hurdles. The first principle of data science, “garbage in, garbage out,” is a question of life and death in cancer care. If an AI is trained on a small or homogeneous dataset, it can create algorithmic bias.

Recent research at Harvard Medical School in early 2026 emphasized that some pathology AI systems are not equally effective for all demographics. Because AI is so sensitive, it can detect very small differences in molecules that are age, race, or sex-related, which are not detectable by the human eye. 

If these demographic factors are used as a representation of disease, the AI system could potentially underdiagnose some demographics. For instance, a system trained on data from older populations could potentially overlook the aggressive triple-negative forms of breast cancer that are prevalent in younger women.

To address this, the research community is shifting towards Explainable AI (XAI) and platforms such as FAIR-Path, which assist in lessening diagnostic gaps by as much as 88%. These platforms enable doctors to understand how an AI system arrives at a particular diagnosis and ensure that the AI system is always a transparent tool and not a “black box” decision-maker.

Bethany Purvis frequently talked about the brave face she had to put up during her five-year battle with cancer. Her experience highlights the eventual aim of AI integration: to ensure that a “brave face” is never a prerequisite for survival. AI has the ability to reveal the diagnostic gap and highlight where our current infrastructure goes wrong.

Technology alone will not be the solution to the cancer problem, but it can be the light that shines to find the problem in the dark. We can move from a reactive strategy of treating the sick to a proactive strategy of preserving the healthy with the right implementation of AI. In honor of Bethany Purvis and others like her, the greatest achievement of 2026 will not be the algorithm but the human decision to use it to give every patient a fair second chance at life.

The Nabateans: Rock-Cut Wonders of the Ancient World

The ringing alarm went off, and I woke up startled, yet realizing that I didn’t have time on my side; I got off the bed almost in a springy fashion and stood next to the hotel room window. Parting the heavy curtains, I could see twilight on the distant horizon. As nature painted colors on the canvas of sunrise in Amman, Jordan, I freshened up and double-checked my backpack. Water bottle, check; shades, and pea cap, my camera gear, check.

I was to return to Riyadh that day after attending a conference over the preceding two days. Before embarking on the trip, I had already decided that even if I got the slightest time window, I would visit the archaeological remains of the city of Petra, which, along with Al Hegra near the city of Madina in Saudi Arabia, are the footprints in the sands of time of the Nabatean Kingdom.

The Journey Begins!

A Medical Doctor fascinated by ancient history, the mysterious, and beyond, I took it upon myself to visit Petra since I had read about it and seen a lot of gorgeous photos. The previous evening, I had roamed around the hotel acquiring information as to the distance and time required for the Petra excursion ( though I had worked out the details before coming to Amman, the locals knew better). Learning enough Arabic to converse with the locals was a plus. I made a deal with a cab guy who was supposed to pick me up the following day, before the crack of dawn.

The Cab finally arrived, and after a brief chat with the driver, we were on our way. It was still twilight, and I had left without having breakfast. It would take three-plus hours to reach our destination, and I had difficulty fighting off the drowsiness ( obviously without my cup of joe in the morning!). He assured me that he would make a pit stop as soon as he was on the main road outside Amman. And that he did, at a small tuck shop making coffee as well, to my delight.

A croissant to complement the kick of the caffeine did the trick. Suddenly, I was upright in the back seat. My mind was racing over what I came across at Petra, how grand it would be, and whether I would be able to see the whole thing and return in time for the flight back home. I also thought about which mentioned in the Holy Quran regarding the ‘Thamud’ civilization. It is purported to have been the very people of the Nabatean Kingdom.

It was explicitly mentioned about their mastery over building immense structures out of giant rocks and mountains, and how they all came to a crashing halt. Snapping me out of my intellectual daze, the cabbie alerted me that our destination was near. It shows how time can be relative, passing by quickly when you are engrossed in something.

We reached the entrance of the ruins of Petra; the driver dropped me off at the entrance while giving me a pseudo-ultimatum of three hours to be out of the place since he said we wouldn’t be able to return to Amman in time. I walked to the ticketing office and got my pass as excited as ever ( after a few selfies at the gate, obviously!). I knew that the whole walk up the path to the city and back would roughly take 4 hours on a brisk foot ( 8 Km in total). I had to make it count and return on time.

The City Structure of Petra and the Nabateans

The Nabateans were Arabs who, in all likelihood, were nomads who originated from Southern Arabia and eventually settled in the area of present-day Southern Jordan, Palestine, and Northern/North-Western Arabia around the 6th century B. Some historians date the Nabatean Kingdom to have been established around the middle of the 4th Century BC to 168 C.E when the Romans annexed it. Petra was the capital of the Kingdom.

As I could see, this area was in the middle of the desert, with extreme sun, aridness, and large red-colored mountains and rock formations. The Nabateans had these conditions to cope with; they were expert builders with exquisite engineering skills. They had the skills to pool and store water in underground water cisterns and aqueducts. This created a ready reserve of water in those times, and we all know how civilization and Kingdoms thrive around water bodies or even oases.

As I walked towards the security checkpoint, I ended up in a barren and dry expanse with a walking trail winding ahead. Raised rock formations eroded by the forces of nature and the passage of time on the sides of the walkway. After five or so minutes of trekking under the scorching October midday sun, huge red sandstone mountains loomed with a vertical break between the rock formations. The sheer size of these natural formations put me in awe.

The entrance through the mountains was marked ‘The Siq,’ which snaked its way through the enormous cliffs. I weighed my photography gear on my back while I kept taking photos. Cool air hugged my face and body as I walked through the twisting trail. This is expected when the shade under the rocks and the temperature difference create a cooling effect in such rock formations. On both sides of the snaking path were inscriptions, pottery, and artifacts neatly decorating the fringes.

Nabateans

Along these walls was evidence of depressions similar to water conduits, which probably were aqueducts carrying water from outside the rock formations into the city for storage and use. Such productive use of nature’s creativity! As we talked along the continuing trail, I noticed that this was a city that was enclosed by a range of large, seemingly impenetrable mountains, which served as fortification for the city.

So, the Siq, though nature’s work of art, served two purposes: first, protection, and secondly, to channel water from outside the city into the surrounding city. Since the city of Petra is lower in elevation than the surroundings, this, combined with marvelous engineering, worked wonders in storing rainwater.  I met a guy from South Sudan who was also busy taking shots. We exchanged pleasantries and shared our mutual interest in Photography & Ancient History.

As we reached the trail’s end, we could see a towering building through the wide slit.  Reaching the spot, we were mesmerized by what appeared to be a magnificent pillared structure, the pillars so smooth, with symmetry between them. The finesse that had gone into making this was nothing short of spectacular. As my homework on the place served me well, this was the ‘Treasury’  or ‘Al- Khazneh’ as they call it, of the city.

The Nabateans were sharply skilled masons. They made immense structures out of sandstone, basically carving them out of the rock. It’s hard to believe structures like these were carved out more than a couple of millennia ago. These people had a definite structure to their society, with a Royal family ruling the city while the common folk performed their assigned duties. There were practically no enslaved people.

The locals spoke a dialect of Arabic; however, one rarely finds inscriptions or records in Arabic in ruins. Most of their history, which has been transmitted, has been through the Greek and Roman historians. As we trekked along the trail, it opened up to a large plain with massive rock formations on the sides and tents, camels, and groups of people thronging the area. This was the ‘street of facades.’ Remains of tombs and typical houses of people were carved into the cliffs higher up on the sides.

There were tombs of the royals and the commoners. The royal tombs were built on the upper side of the cliffs, while there were holes and caverns carved out below them. These are purported to be houses/tombs of the commoners. Flocks of people were gathered on the highest points of the sandstone cliffs to take photos and get a glimpse into these houses. There was a hustle of people in the central area of the plain, where there was a thriving marketplace—stalls selling souvenirs and trinkets, tuck shops selling drinks and snacks in the scorching heat.

Camels and mules with multicolored saddles gave me a feel of what it would have been like back in the Kingdom’s heyday. There was a  small ‘Theatre’  as in a Roman theater, with a semicircular theater which could probably seat 50 or so people. This was meant for public events or perhaps entertainment. The structures I had seen till now were reminiscent of Greek & Roman architecture. From around 2000 to 2400 years ago, the Greeks were thriving in the regions bordering the Kingdom, and the Romans annexed and settled in the area later on.

Religion and Civil Matters

The society of Nabateans had special rights of equality for women. They rose to the position of Priestesses and had property rights and the right to co-rule. The idols of Allat, Manawaat, and  Al-Uzza were female deities. They had attributed different responsibilities to a host of Gods.

The most enduring one is Dashura, the sun god. The inscriptions can be on coins even during the Roman tenure after they annexed the Kingdom. This is reflected in their practice of idol worship as well. They held public ( festivals ) but mostly private worship. The inscriptions and markings reflecting these deities can be seen in their tombs, on top of doorways, and on pottery.

My Pal and I scurried onwards and came across a freestanding structure (the largest freestanding structure in the city ), tall and partially intact. It was called ‘Qasr-bint.’ It was the city’s main temple, and the idol deity Dushura was worshipped here. The temple is made of blocks with decorative plasterwork on both the inside and outside of the walls. Strings of wood course between the blocks and line the walls. This was quite intricate civil engineering.

We came across this sizeable stair structure with an endless number of steps to the top, where numerous bases of pillars could be seen in a row. It was a temple. Again, it probably served ceremonial and religious purposes. The remains of the pillars remind us of how grand the structure would have been. I went up there and spent a few minutes carrying on with my newfound pal.

A few men dressed as Nabatean guards were standing near an entrance of sorts along the path. This looked like a check post that would have served the purpose of security for what lay ahead. The men wore an imitation of armor and helmets and were wielding spears. They gleefully posed for photos with us!

Nabateans’ Trade and Wealth

Further hurrying down the trail, we found makeshift shops and permanent ones selling some stuff in large bowls. On closer inspection, it was a wide, colorful range of spices and frankincense (aromatic extracts from particular tree bark). Frankincense has been used and traded for millennia. It is burnt, and the aroma, which is earthy, sweet, and musky, is said to purify the surroundings and calm your soul. The Nabatean Kingdom’s primary revenue was generated from the trade route extended from the Yemeni coast in Southern Arabia to the dead and the Mediterranean Sea.

This route enabled them to do business and interact with the civilizations bordering them. Namely, the Greeks, Romans, Persians, and Assyrians. They had exclusivity to this trade. The returns came in thick and fast, which enabled the Kingdom to flourish by leaps and bounds. They had an outpost called Al Hegra, which in present-day is around 350 km from the Holy City of Madina. The output served as a pitstop for the trading caravans. Al Hegra also had a thriving population. The tombs and houses carved out of sandstone rock can still be seen standing amidst the barren desert.

The success of their trade and immense wealth were reasons for envy for the neighboring Greeks, with numerous attempts made to capture parts of the route; however, they were warded off by the Nabateans. Demetrius, son of the Greek King, Antigonus I, tried to raid the city in 312 B.C but failed and, in a later encounter, suffered the same fate again.

Nabateans: The Collapse of Civilization and Epilogue

To my surprise, we ended up near the entrance of the city of Petra. I bought a few souvenirs from the market, walked towards the taxi stand, turned back, and gave it one last look. Realize how Civilizations and Kingdoms flourish with such majestic skills and wealth, and how they eventually fall.  They went to war many times with the Greeks in skirmishes, which they finally won, but they were no match for the invading Romans at the turn of the common era  ( C.E ).

Numerous Nabatean Kings succeeded each other. However, considered to be their greatest King was Arteus IV, reigning from 9 B.C to 40 C.E. Under him, the Nabateans regained territory from the Romans. The latter had captured it in earlier confrontations. Art, crafts, and civil rights all flourished during his reign. However, the kings succeeding him lost more territory to the Romans, and eventually, the Kingdom weakened, and wealth dwindled due to the loss of trade routes.

The Roman Empire was growing in power simultaneously and eventually annexed the region as the Roman Province of Arabia Petra in 106 C.E. The cities under Roman rule went into a downward spiral. However, a devastating earthquake shook the cities in the latter half of the 4th century C.E. This was the final nail in the coffin.  Many died along with the loss of infrastructure. The Roman Empire tried to resurrect the city’s spirit by re-igniting commerce and building churches. It said that they forcibly tried to convert many locals to Christianity.

Many probably fled the area with no sense of ownership due to religious persecution. Another earthquake struck the region in the 6th century C.E. This led to widespread destruction and eventually the abandonment of the cities. This is further confirmed when, during the expansion of the Islamic Empire during the reign of Caliph Umar, the Muslim armies found these cities deserted and forlorn. European explorers discovered the region in the 19th and 20th centuries, and the world was exposed to these magnificent ruins. The city was declared a World Heritage in 1985 and one of the 7 New Wonders of the World in 2007.

I got into the cab and went on my way to the Hotel in Amman city center. What I witnessed was a testimony to how Civilizations rise to power, no matter their status, prowess, or grandeur. All are swept away by the relentless flow of time. The remains of their presence are an eye-opener for us on how fragile we are.

Gut Health and Lifestyle Medicine: Small Habits, Lasting Change

0

Before entering the field of Lifestyle Medicine (LM), I was a physician constantly searching for a more definite path toward healing and cure, especially for chronic diseases where patients often remain dependent on pills, capsules, and injections for the rest of their lives. Over time, medications may lead to additional side effects, creating a cycle where even more medicines are needed to manage those complications. This question always stayed with me: Can true healing be possible beyond lifelong symptom management?

My journey in Lifestyle Medicine began almost five years ago, and I can happily say that it positively answered many of those unanswered questions. Through extensive learning and certifications, including a Postgraduate Certification (LMPC from Riphah International University), Personalized Lifestyle Medicine and Circadian Rhythm Alignment (SWIPE by Dr. Shagufta Feroz), Dip. IBLM (American Board of LM) and Blue Zones Certification (American College of LM), I gradually incorporated LM principles into my own life, clinical practice, teaching, and online drugless LM clinic. From the very beginning, I witnessed encouraging changes not only in myself, but also in my patients and students.

 “Lifestyle Medicine is an evidence-based approach that uses healthy lifestyle modifications as a therapeutic tool to prevent, manage, and even reverse chronic diseases. It works on the correction of six pillars of lifestyle, i.e., Optimal Nutrition, Physical Activity, Stress Management, Avoidance of Risky Substances, Restorative Sleep, and Social Connection.

However, while in my LM practice, teaching, conducting awareness sessions, workshops, and community programs, I repeatedly observed one important challenge: people understood what to do, but struggled with how to stay consistent and how to prevent relapses. They needed support, accountability, connection, and continued guidance until healthier habits became sustainable.2

This realization became the foundation of my four-week “Gut Reset & Sugar Balance Program.” I noticed increasing concerns related to gut issues, dysbiosis, cravings, poor meal timing, unhealthy food combinations, lack of circadian rhythm awareness, and confusion caused by overwhelming online information and quick-fix approaches. Many people received advice from LM experts, but long-term behavior change remained a difficult challenge.

Unlike conventional diet-focused programs, this initiative was not based on calorie restriction or unrealistic promises of overnight transformation. Instead, it focused on awareness, education, and understanding the “what, why, how, and when” behind healthy habits. Participants learned about hydration, meal timing, mindful eating, balanced plates, sleep hygiene, circadian rhythm alignment, stress management, and sustainable habit formation through simple, interactive learning 3, 4.

The program consisted of weekly online sessions over four weeks, with only a few achievable goals introduced each week to prevent overwhelm. Polls, reflections, and group discussions created accountability and motivation, and participants highly appreciated this simple and practical structure.

One of the most important observations during this program was that many participants were not lacking information; rather, they were struggling with consistency, overwhelm, and the emotional fatigue that comes from repeatedly trying and failing restrictive health plans. Several participants expressed that they had previously followed different diets, social media trends, or temporary routines, but found them difficult to sustain in real life. This highlighted an important reality in Lifestyle Medicine: behavior change is not merely about knowledge, but about creating practical, realistic, and emotionally manageable habits that can fit into daily life.

The group-based interactive structure of the program also played a significant role in motivation and accountability. Simple daily reflections, polls, reminders, and shared experiences created a sense of connection among participants. Many participants reported that they felt “heard,” “understood,” and less alone in their health struggles. This emotional and social aspect of healing is often underestimated in chronic disease management, despite its strong influence on motivation and long-term adherence.

Another meaningful insight was the positive response toward gradual habit formation. Instead of introducing multiple overwhelming goals at once, participants were encouraged to focus on only a few achievable changes each week. Surprisingly, this simple approach improved compliance and reduced resistance toward lifestyle modifications. Over time, participants themselves began noticing how one healthy habit naturally influenced another — improved hydration encouraged mindful eating, better sleep supported reduced cravings, and regular movement improved emotional well-being and discipline. This interconnectedness reinforced the concept that health behaviors rarely work in isolation; rather, they support and strengthen one another over time.

The outcomes reported by participants were deeply encouraging. Many experienced improved hydration, reduced cravings, better digestion, less bloating, increased energy, improved sleep hygiene, reduced screen time, mindful eating, increased physical activity, stress management strategies, and even improvements in allergies. More importantly, many participants described feeling more connected with their own body signals, emotions, and daily routines.

Personally, reading their testimonials and reflections was a moment of gratitude for me. This experience reinforced an important lesson for me: people respond better to simplicity than restriction. When individuals understand why a habit matters, their motivation and consistency improve naturally. I also witnessed how awareness itself can become therapeutic.

Sustainable health transformation often begins not with extreme interventions, but with awareness, support, consistency, and helping people feel heard and connected in their own healing journey 5.
