Humanity had gazed skyward at the vast expanse of stars and planets for millennia. Yet the true nature of the universe remained shrouded in mystery. This all changed with the invention of the telescopes, which served as transformative tools that became our cosmic eye and altered the landscape of astronomical discovery.
Most astronomers use telescopes on the ground to look through the Earth’s atmosphere to see into space. The atmosphere blocks out light from part of Electromagnetic Spectrum. These telescopes offer a clear view of the night sky, allowing for capturing stunning celestial phenomena and collecting valuable data. ([1], n.d.)
Discovery of Galileo Galilei
In the 17th century, he improved his telescope and witnessed the previously unseen craters on the Moon, four moons of Jupiter (Io, Europa, Ganymede, Callisto), and sunspots on our host star. These discoveries challenged the prevailing geocentric model, where Earth was believed to be the center of the universe. Galileo’s observations supported the heliocentric model, placing the Sun at the center of our solar system. ([2], n.d.)

Edwin Hubble Discovery
Perhaps the most groundbreaking discovery made with a ground-based telescope was achieved by Edwin Hubble in 1929. By observing distant galaxies, he noticed that their light was redshifted, indicating they were moving away from Earth.
This realization led to the theory of the expanding universe and resulted in the formulation of the Big Bang theory, which is our current understanding of the universe’s origin.
The Role of Radio Telescopes
Radio telescopes like the Atacama Large Millimeter/submillimeter Array (ALMA) play a crucial role in cosmic exploration. Unlike optical telescopes that detect visible light, radio telescopes pick up on the faint radio waves emitted by objects in space, including:
Interstellar Gas and Dust Clouds
These clouds, invisible to optical telescopes, are crucial sites for star and planet formation. By observing them, ALMA observes the hidden processes of stellar nurseries. It also discovered a supermassive black hole in Messier 87 galaxy. ([3], n.d.)

Exoplanetoty atmospheres
Radio telescopes detect molecules in the atmospheres of exoplanets, potentially hinting at the presence of conditions suitable for life. The large exoplanet TVLM 513b was discovered in 2020. ([4], n.d.)
Giant Leaps with the Very Large Telescope (VLT)
With its four-unit telescope working together, the VLT is one of Earth’s most powerful optical telescopes. This ground-based marvel has made significant contributions to our understanding of the universe, including:
Formation of Galaxies
Detailed observations of distant galaxies by the VLT have provided insights into the early universe and the processes that led to the formation of galactic structures. Chile’s Very Large Telescope (VLT) discovered a cluster of 20 galaxies. ([5], n.d.)
Universe with Space Telescopes
Space-based telescopes like the James Webb Space Telescope (JWST) and Hubble Space Telescope (HST) offer unparalleled advantages as they operate above Earth’s atmosphere; they are free from light pollution, atmospheric distortions, and the limitations of the visible light spectrum.
JWST has more resolution and can observe infrared light of longer wavelengths than HST. This allows them to peer deeper into space and observe objects invisible from Earth.
Gazing Back in Time with JWST and Hubble
With their ability to observe infrared light, JWST and HST act as time machines. By capturing light that has traveled for billions of years, they offer a glimpse into the universe’s infancy. Their observations have yielded incredible discoveries, including:
The first Stars and Galaxies
JWST and HST have captured images of some of the very first galaxies formed after the Big Bang, allowing us to study the universe’s earliest stages of evolution. JWST has confirmed a proto-cluster of seven galaxies at a distance that astronomers refer to as redshift 7.9, or a mere 650 million years after the Big Bang, as shown in the figure. ([6], n.d.)
The figure shows the galaxies 650 million years after the big bang ([6], n.d.)
Active Galectic Nuclie (AGN)
Space telescopes have observed these powerful, energy-emitting regions at the center of some galaxies in incredible detail, revealing insights into their formation and behavior. JWST reveals active supermassive black holes that were surprisingly rare in the early universe. ([7], n.d.)
Supernovae and Nebulae
The powerful explosions mark the end of a star’s life and enrich the interstellar medium with the elements necessary for new star and planet formation. Additionally, space telescopes have captured images of various stellar nurseries. ([8], n.d.)
The Future of Telescopic Exploration
While the discoveries made by JWST and Hubble are truly remarkable, Euclid promises to push the boundaries of our understanding even further. Euclid will act as a cosmic cartographer mapping the distribution of dark matter, the mysterious invisible substance thought to comprise a significant portion of the universe’s mass.

The Synergy of Ground and Space
The synergy between ground-based and space-based telescopes allows astronomers to create a more complete picture of the cosmos. For example, a space telescope might detect a distant galaxy, and a ground-based telescope could then be used to measure its redshift, providing information about its distance and the expansion of the universe.
Technological advancements in radio telescopes, like the next-generation Square Kilometer Array (SKA), will offer even greater sensitivity and resolution, revealing faint and previously undetectable objects.
The Spark of Curiosity— Astronomy’s Impact on Science and Society
The journey of telescopic exploration has not only revolutionized our understanding of the universe but has also significantly impacted science and society as a whole; it has applications in optics, engineering, and material, from medical imaging to fiber optics communications.
Telescopic discoveries spark curiosity by inspiring future generations to explore, innovate, and push the boundaries of human knowledge.
As we continue to develop more powerful telescopes and refine our observational techniques, the coming decades promise even more groundbreaking discoveries. The universe holds countless secrets waiting to be unveiled, and telescopes remain our powerful tools to unlock them.

The bus jolted to a stop, waking Hassan abruptly. Stepping off, he was hit with a blast of intense heat from the midday sun, which hung high in the cloudless sky like a relentless white disk. Sweat formed on his forehead despite the cap he loosely held over his head. Hassan squinted at the “park” across the street– a dusty area of cracked earth with a few scraggly trees offering minimal shade.
Supposed to be a refuge from Karachi’s scorching summer, a place to escape the oppressive heat trapped between towering buildings, it was a constant disappointment. Hassan sighed, feeling the familiar disappointment settle in his chest. Surely, there had to be a better way.
Hassan’s story was not unique. Millions of Karachiites faced the harsh reality of urban heat. With limited green spaces and temperatures regularly exceeding 38°C, finding relief from the relentless sun is a daily struggle.
However, what if the solution wasn’t just enduring the heat but actively fighting against it? The answer lies in a solution as simple as nature itself – creating a network of thriving urban green spaces.
Amidst the rising global temperatures, the world is becoming increasingly vulnerable to the effects of climate change. The recent global climate report released by NOAA states that April 2024 was the warmest April ever recorded worldwide, surpassing the previous record set just four years prior. As Pakistan ranks fifth on the list of countries most at risk from climate change (UN-Habitat, 2023), the urgency of addressing these challenges becomes ever more apparent.
But why does the heat feel so intense in urban areas like Karachi? It’s due to the Urban Heat Island (UHI) effect. Buildings, roads, and other infrastructure absorb and release more of the sun’s heat compared to natural landscapes like forests and bodies of water. This is especially true in urban areas where there are many structures and limited greenery, resulting in localized areas of higher temperatures known as “heat islands.”
The lack of green spaces that provide a cooling effect causes urban temperatures to skyrocket, making summers even more unbearable. Studies have shown that surface temperatures in cities can be a staggering 10-15°C higher than in surrounding rural areas (Mentaschi et al., 2022).

Heat Islands—Impact on Quality of Life
The Urban Heat Island (UHI) effect significantly impacts the quality of life in Karachi. It causes heatwaves to last longer in the city, resulting in abnormally hot and often humid weather. This has serious consequences for health, such as heat exhaustion, heatstroke, and even death, particularly among vulnerable groups like children, the elderly, and those with pre-existing health conditions.
A recent project by Aga Khan University seeks to measure extreme heat’s impact on maternal and child health. Researchers are concerned about the greater impact of heat stress and temperature fluctuations on pregnant women. Gynecologist Safia Manzoor from Lyari General Hospital states, “We have noticed an increase in cases of pre-term births during hot weather.”
In addition, high temperatures cause air pollutants, such as smog, to become trapped close to the ground, exacerbating conditions like asthma and other respiratory illnesses. This makes breathing difficult and increases the risk of respiratory attacks. Residents rely more heavily on air conditioners and fans to cope with the heat, resulting in higher electricity bills and straining Karachi’s power grid. This leads to more frequent power outages and energy shortages.
A US-based study has indicated that for every 1°F increase in temperature, there is a 1.5 to 2 percent increase in electricity demand. As most power plants in Karachi depend on fossil fuels, this heightened energy demand contributes to increased air pollution and greenhouse gas emissions, further contributing to the ongoing global warming cycle.
What can be done?
Scholars have been actively exploring effective ways to improve the urban thermal environment and decrease the negative impacts on cities. Urban parks stand out among the most reliable and natural remedies for extreme heat. Studies have shown that green spaces like urban parks and roadside greenways can significantly lower surface temperatures and overall city heat.
This is because they provide shade and evapotranspiration, creating a ‘Park oCol Island’ (PCI). Trees and plants in these areas block direct sunlight and release water vapor through evapotranspiration, cooling the nearby air and surfaces. This combination effectively reduces temperatures within parks and their surroundings, helping to counteract the urban heat island effect and regulate the nearby environment.
However, urban planners are still exploring the best places to plant trees and their effectiveness in Karachi’s specific climate. To address the growing problem of UHI, I would like to share insights from a recent research paper by Gajani (2024), highlighting the remarkable potential of Urban Green Spaces to cool down the city and revive its vanishing biodiversity.
This research identifies areas with the highest heat stress and locates thermal hotspots to prioritize the construction of green spaces in those areas.
The Cooling Potential of Urban Green Spaces.
To understand how much a green area can cool its surroundings, the study used remote sensing satellites to measure the land surface temperature (LST) across four different parks located in Karachi during the summer of 2022. LST is the temperature of the ground’s surface as measured from above.
The author then identified the “park cooling intensity,” which is the difference in temperature between the inside of the park and the area up to 500 meters outside the park boundary. The goal was to see how far the cooling effect of the park extends and how the temperature decreases as you get closer to the park.
Although temperature profiles fluctuate, all urban green spaces (UGS) in Karachi show a general trend of cooling. For example, the cooling effect in ‘Karachi Golf Club’ and ‘Clifton Urban Park’ extends to various distances, around 150 to 240 meters, and stabilizes beyond 420 meters for others.
This variation is often due to the size and shape of the parks, where it has been studied that larger parks tend to have a more pronounced cooling effect.
Researchers found unusual trends when studying the cooling potential of the city’s biggest park, Safari Park in Gulshan-e-Iqbal. Its cooling intensity values were recorded as negative. This might be due to the topography, where trees are mostly concentrated along the edges, while the central areas have limited tree coverage, leading to erratic fluctuations in recorded temperature.
This highlights the need for urban planners and administrators to prioritize preserving and enhancing the park’s design for effective urban temperature mitigation. When planning an urban park, its size and shape should be kept as a primary factor to consider.
This highlights the need for urban planners and administrators to prioritize preserving and enhancing the park’s design for effective urban temperature mitigation.
Thermal Hotspots— Detection and Analysis
To further analyze the thermal disparities within the city, researchers identified localized clusters of ‘Hotspots’ using the Getis Ord (Gi*) approach. These clusters represent areas where high LST values are grouped by other high LST values.
Results indicate that parts of Karachi face scorching heat due to large areas of empty land with little greenery. This is especially true in Karachi West district, where neighborhoods like Mauripur and Mangopir see average surface temperatures exceeding 42°C!
In contrast, areas with more parks and green spaces, like Karachi Central and East, have fewer hot zones and cooler temperatures.
Planting trees and creating green spaces in these vacant areas is key to making Karachi more comfortable. This would help reduce hot zones and cool down the entire city, benefiting everyone. The good news is that areas near the Arabian Sea, like Clifton and Kiamari Town, tend to be cooler.
This is because of cool sea breezes and the presence of the Karachi coastline’s mangrove belt. However, even these areas can get very hot during heatwaves. Buildings that are close together, poorly ventilated, and made with low-quality materials that can trap heat are making things worse.
Location of the hot/cold spots within Karachi municipality (Gajani, 2024).
This study highlights the power of urban parks as natural air conditioners, significantly cooling down their surroundings. By strategically planting trees in the hotspot areas, we can create a targeted plan to make Karachi a cooler, healthier city for everyone.
Educating both the public and city officials about the benefits of green spaces is key. Imagine a network of parks and tree-lined streets strategically developed in Karachi’s hottest districts, like Karachi West and Malir. This wouldn’t just bring down temperatures; it would create havens for recreation and improve our overall well-being.
Challenges in Developing Urban Green Spaces—Expert Insights and Solutions
According to a study conducted by the World Health Organization, it is recommended that each individual living in a sustainable city has access to a minimum of 9 m² of green space, with an ideal value of 50 m² per capita. Karachi falls significantly short of this standard, highlighting the urgent need for action.
Mr. Haq points out that one of the primary obstacles is finding appropriate space in the densely populated city where a long-term sustainable forest can thrive. The landscape layout conflicts with existing infrastructure, buildings, and transportation networks often act as physical barriers, making it difficult to carve out sizeable green zones.
Moreover, government agencies, NGOs, and even individuals only prioritize short-term visibility over long-term sustainability. Although there are frequent plantation drives across the city, these efforts often lack strategic planning.
Instead of merely planting trees for publicity, the focus should be on identifying and protecting areas where a long-term urban forest can be developed. This approach would ensure the survival and growth of green spaces rather than temporary improvements.

Additionally, he emphasizes the importance of selecting the right type of trees and the appropriate planting time to ensure their growth and sustainability. Many people are unaware of these factors, leading to ineffective plantation efforts. Karachi’s coastline also offers a unique opportunity to plant and protect mangroves, which are crucial for the ecosystem.
Therefore, sincere commitment and vision are necessary to ensure these green spaces are maintained and protected from urban encroachment and poaching.
He suggests creating ‘peri-urban forests’ in Karachi when asked about the way forward. These forests would be located on the outskirts of the city, where there is currently mostly barren land. These peri-urban forests would act as green buffers around the city, significantly reducing the urban heat island effect and improving air quality.
He emphasizes that this transformation requires not only planting trees but also selecting species suited to the local climate and conditions and that proper patience is crucial as these forests need time to mature and become effective.
As we face the escalating challenges of urban heat and climate change, it becomes clear that the responsibility to create a sustainable future lies with each one of us. Transforming Karachi through the establishment of urban green spaces is not only an environmental necessity but also a moral obligation. Robert Swan wisely pointed out,
“The greatest threat to our planet is the belief that someone else will save it.”
It is time for every citizen, planner, and policymaker to step forward, act, and commit to greening our city. Doing so can alleviate heat stress, enhance air quality, and forge a habitable environment for future generations. Let’s embrace the challenge, for a greener Karachi is a healthier, happier Karachi for all.

Since time immemorial, people have celebrated the trend of adorning and decorating themselves. This practice often arises from a desire to improve upon perceived physical flaws or enhance one’s natural beauty. Cosmetics serve as tools to fulfill these psychological needs.
Although applying various cosmetics can bring a radiant glow to the face, boosting individuals’ confidence as they feel beautiful, the hidden ingredients within these beauty products can diminish environmental brilliance and lead to associated health issues.
Cosmetics include lipsticks, creams, powders, lotions, nail polish, shampoos, mascara, perfumes, etc. People of all ages and spheres widely use them.

Hair Dye
Brittany Murphy has addressed the prominence of hair dyes well, saying, “If you can’t change your surroundings, change your hair color.”
We’re often in the habit of changing hair color according to our needs and mental state. Now, let’s delve into the hidden chemistry of hair dyes, clearly mentioning the associated adversity.
Coal tar, a mixture of chemicals derived from petroleum, is also used to generate cosmetics colors with a five-digit Colour Index (CI) number. The particular coal tar dye commonly used in hair dyes is p-phenylenediamine. The color concentration of the hair dye is proportional to the ratio of phenylenediamine used.
According to the European Union, p-phenylenediamine is categorized as toxic and is fatal to aquatic organisms, causing appalling effects in the marine environment. It is known to be carcinogenic and is reported to cause pharyngeal irritation, asthma complications, and dermatitis. Other coal tar colors are also categorized as cancer-causing agents.
Besides the main constituent, p-phenylenediamine, other dyeing agents adversely affect human health. P-aminophenol aggravates asthma, causes eye and skin issues, and promotes methemoglobinemia.
The dye 4,5-diaminopyrazole poses eye damage and skin allergies. Pyrimidine causes eye issues and dermatitis. Resorcinol promotes problems in the eyes, skin, and respiratory system.
Moreover, drowsiness and dizziness are related concerns with using hair dyes, which have this component in their composition. Meta-aminophenol triggers skin sensitization, and meta-phenylenediamine causes eye and skin concerns.
It also affects the kidneys and blood, leading to renal failure and methemoglobin formation. Pyridine, when part of hair dye, initiates irritation of the eyes, skin, and respiratory system and poses dizziness. Toluene-2,5-diamine induces pro- and anti-inflammatory responses.
The presence of aluminum compounds and other heavy metals is harmful to the brain. Many dyes lack approval as food additives, yet they are still included in lipstick compositions.
Long-term use of hair dyes can lead to developing non-Hodgkin’s lymphoma in women. In one research study on hair dye reactions conducted in India with 110 volunteers, individuals suffered from headaches (63 percent) and itching (38 percent).
Other chemicals found in lipstick compositions include polymethylmethacrylate, methylparaben, and polyparaben. Photo, Unsplash
Lipstick
The most common cosmetic type to be used is lipstick, whether the lady is a makeup person or not; it is the minimum possible make-over done daily, especially by working ladies.
Toxic elements such as Al, Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, Sb, and Zn are found in lipsticks in excess. Some of these metals are not easily decomposed in landfills, causing pollution. The health impacts of these heavy metals are immense, and the longer the exposure time, the greater the seriousness of the side effects.
Aluminum— Gene alterations, oxidative stress, and breast cysts. Cadmium— Skin bruises, renal failures, chronic rhinitis, and oseotoxicities. Chromium— Carcinogenic and asthma inducer. Nickel— Respiratory, reproductive, renal disorders, and carcinogenic effects.
Other chemicals found in lipstick compositions include polymethylmethacrylate, methylparaben, polyparaben, retinyl palmitate, dyes, tocopheryl acetate, lead, propylene glycol, and methylparaben, which can cause allergies and cancers.
In an investigation, the inductively coupled plasma optical emission spectrometric method (ICP OES) was utilized to evaluate the presence of eleven harmful elements (Al, Cd, Cr, Co, Cu, Ni, Pb, Fe, Sb, Mn, and Zn) in fourteen lipstick samples. The hazard index (HI), hazard quotient (HQ), and average daily intake (ADD) were computed to determine the health risk assessment. Iron (Fe) had the greatest mean ADD value, while cobalt (Co) had the lowest.
The shampoo is essential to our daily lives. As Rory Power rightly said, “Even when there’s no bread, there’s always shampoo.”
Shampoo
The shampoo is essential to our daily lives. As Rory Power rightly said, “Even when there’s no bread, there’s always shampoo.”
The care and treatment of hair and scalp conditions often involve shampoo as a common practice. Soap was the only available hair cleanser until the first non-alkaline shampoo was introduced in 1933.
The main environmental concern with shampoos is their biodegradation of surfactant content. As it is discharged in much smaller amounts than detergents, it is often ignored and expected to cause no irreversible environmental harm.
However, some shampoo ingredients, such as coal tar, formaldehyde, halogenated aromatics, and musk, have been addressed as impacting the environment and health.
Amongst the various parameters measuring shampoo safety, aquatic toxicity and biodegradability hold prime value. The active ingredients in shampoo, such as sodium lauryl sulfate, resorcinol, parabens, triclosan, and dioxane, have been reported to pose irritation and eye damage concerns.

Nail Polish
The beauty of hands is glorified through multifarious nail colors, and a complete makeup package never goes without it.
The leached and solubilized extracts from nail polishes are investigated to be mutagenic and cytotoxic for humans, and a much-pronounced effect is observed for the solubilized extract. The nail paint extracts pose alarming risks to the aquatic environment as they are studied to be acutely toxic for zebrafish embryos.
It is unknown how much of the chemicals released from nail polish disposal currently exist in the environment. Therefore, the improper disposal of nail polish may pose risks to human and environmental health.
Many chemicals in nail polish bottles, namely phthalates, xylene, acetates, formaldehyde, camphor, etc., may induce reproductive system disorders.
Maurice Rousel once said, “Your fragrance is your message, your scented slogan.”
Perfumes
Maurice Rousel once said, “Your fragrance is your message, your scented slogan.” People of all ages love a well-scented and fragrant environment. The smell of flowers, fresh grass, and aromas of all kinds, both natural and artificial, adorn individuals’ aesthetics.
Fragrances are much-overlooked pollutants, though they accumulate in the food chain through water. Once fragrance molecules mix with other pollutants already in the air, they form irritating and allergic substances, such as peroxides and inflammatory substances, causing asthma and related problems. The respirable particles have a size range of 10 µm or less. With the addition of D-limonene in the office, the size of the molecule increases to 100 times due to accumulation.
The decomposition of musk compounds takes time in the aquatic environment. They function as organic pollutants by accumulating in the tissues of fish. The constituents of prime value in fragrance manufacturing are benzaldehyde, acetone, ethanol, formaldehyde, phthalates, linalool, camphor, and many more, which cause serious health concerns like kidney damage and irritation in various body parts.
Other harmful Cosmetics
The contents of hairspray are liable to contribute to ozone depletion. They can cause hormonal disruptions and allergies in human beings. Triclosan, present in deodorant, resides on the water’s surface and harms aquatic organisms. All the ingredients can cause respiratory disorders, irritations, and headaches.
Blusher is dangerous to marine and aquatic organisms, with long-term side effects—the contents in the blusher cause irritations and hormonal imbalances. Face foundation contains carcinogenic ingredients, and its heavy metals are not biodegradable, leading to land pollution in landfills. The same issue applies to heavy metals, which are quite prominent in mascara and eyeliner.
The manufacturing processes involved in lotion generate significant pollution, and the lotion itself is non-biodegradable. Lotion may cause hormonal imbalances and irritations. Some sunscreen products are reported to affect coral reefs. The packaging waste of cosmetic products is a big challenge for many countries, posing many environmental issues.
Final Words
The idea of improving outward looks has been very well conceived by people of all ages around the globe. When people fight for the necessities of life, the beauty industry remains at its peak. Keeping our inner selves satisfied, we create many factors of dissatisfaction in the environment.
Moreover, temporary improvement of looks leads to long-term and permanent health setbacks. The importance of the musts cannot be addressed, yet careful and limited exposure to these would cater to the needs of personal and environmental levels.

Pakistan experienced two catastrophic floods in 2010 and 2022, affecting millions of people. From 1950 to 2011, Pakistan faced a flood every three years. These flooding events resulted in the death of 8887 humans and the economic loss of $19 billion1.
The 2010 super flood affected 0.2 billion people; 1985 people died, and the financial loss was $9.7 billion. The 2022 monsoon flooding resulted in the loss of 1033 lives, 5.4 million people displaced, 2 million acres of crops and 2 million homes destroyed, and 72 districts declared calamity hits.
Pakistan has negligible carbon footprint contributors but faces harmful impacts from climate change. According to the German watch Global Climate Risk Index (GCRI), for countries most affected by flood, Pakistan ranked at 8th position and is at 7th among countries vulnerable to climate change2.
The impact of floods on different areas of Pakistan varies according to their geographical characteristics, and measures are taken to manage disastrous effects. Punjab is the most populous and agriculturally productive province and often faces more destruction due to floods.
Floods in Punjab came because of heavy monsoon rainfall, overflow of rivers, and breaching of the canal system. The agricultural sector of Punjab causes the most destruction, resulting in crop loss and livestock mortality. The urban area faces infrastructure damage and disruption of network systems.
In Sindh, floods occur because of coastal and riverine flooding, destroying crops, mainly rice, sugarcane, and cotton. In Khyber Pakhtunkhwa and Gilgit Baltistan, another type of flooding was hit due to heavy rainfall and glacier melting. Floods in KPK destroy infrastructure, hinder relief efforts, and worsen poverty in already marginalized communities.
Balochistan eastern regions experience riverine flooding and occasional flash floods in its mountainous areas. Limited infrastructure development in these areas makes it challenging to provide immediate relief assistance and health care services to remote areas during floods.

Calamities like floods bring a lot of chaos in developing countries. The recent flood in Pakistan in 2022 resulted in the displacement of 33 million people3. Numerous IDP camps were established in affected areas to provide temporary shelter, food, and necessities to the displaced people. These camps were established in schools, open spaces, and government buildings to accommodate the influx of displaced people.
Temporary shelters like tents were provided to displace people, often overcrowded, poorly ventilated, and susceptible to flooding during heavy rainfall. Access to clean drinking water in camps has been limited, increasing the risk of waterborne diseases like hepatitis, Malaria, dengue, cholera, and skin infection4.
Poor waste management and drainage systems in camps result in an unclean environment, increasing health risks for camp residents. In overcrowded camps, there is a greater chance of the rapid spreading of infectious diseases. Healthcare workers, medicines, and medical supplies are often limited to camps.
In the 2022 flood, about 650,000 pregnant women lived in IDP camps,100,000 pregnant women were in Sindh,73,000 women had delivery dates of the next month, and they urgently needed skilled birth attendants, newborn care, and financial support. Women, children, and people with disabilities were vulnerable in IDP camps and faced abuse and negligence.
Affected People felt anxiety and depression as they lived in temporary shelters— and faced trauma due to the challenging situations during this whole disaster.
Climate change has increased the intensity of natural disasters like floood by changing weather patterns. Due to excessive human activities like burning fossil fuels, the earth’s temperature keeps rising. The likelihood of rainfall increases as warmer air holds moisture, leading to flooding.
The Karakoram and the Himalayas rely on glacier melting for their river water, used for agriculture, hydropower plants, and drinking. As the temperature surges, the melting of glaciers increases, leading to rivers. Deforestation, urbanization, and expansion of agricultural land increase the risk of flooding.
In Pakistan, flood management measures have been practiced since the establishment of the Federal flood commission in 1977. The provincial government deals with the execution of protective work, whereas the federal government deals with controlling funds while ensuring timely decisions5.
The government’s structural measures to control flood water are building dams, spurs, walls, and channels. Embankments prevent overflooding and spur stop soil erosion. To protect the irrigation network, villages, and towns, buns are made. Pakistan, being a riparian country, faces challenges in managing floods.
The Flood Forecasting Division of Pakistan’s Meteorological Department and the Water and Power Development Authority (WAPDA) are responsible for forecasting floods. Provincial irrigation and drainage authorities deal with river design, development, and maintenance. They also measure the discharge of rivers, canals, and drains to foretell floods and develop strategies in case of emergency.
The relief department at the provincial level is responsible for conducting surveys and ensuring the maintenance of bunds before flooding season. In 2018, a project known as the 10 Billion Tree Tsunami was initiated for the country-wide plantation of trees to combat global warming effects.
Climate change interacts with socioeconomic challenges and increases people’s vulnerability to these natural disasters. Several strategies can be implemented to make climate-resilient Pakistan transition to non-renewable energy resources— minimize Pakistan’s reliance on fossil fuels and reduce greenhouse gas emissions.
Create awareness among people about energy conservation. Promotion of climate-friendly agricultural practices like conservation tillage, crop rotation, agroforestry, and efficient irrigation techniques to increase agricultural production— and reduce the level of greenhouse gases produced by the agriculture sector.
Afforestation and deforestation reduce carbon dioxide levels in the environment and conserve biodiversity. Water conservation measures and rainwater harvesting techniques should be implemented. There must be a plan and an early warning system in case of any emergency so the community can cope with the consequences of natural disasters.
Promoting public transport can improve air quality is the need of time. We need to raise awareness among the people about climate change, its causes— and how it drastically affects our future generations.
Better and more efficient policies, regulations, and incentives should be implemented nationally and locally. Although Pakistan’s government is taking initiatives to mitigate climate change, more robust efforts are required to reduce climate change.

In 2013, a marine heat wave swept across Southern Australia, raising sea surface temperatures to a scorching 27 degrees Celsius, well above the average of 24 degrees. This led to a distressing ecological event as a prolonged and widespread fish-kill occurred, affecting 29 species of marine life and spanning 2900 km of coastline from January to May 2013.
Studies revealed the presence of abrasive and harmful phytoplankton in unnaturally high concentrations, raising suspicions about the cause of the mass mortality event. Laboratory tests revealed the grim reality faced by the marine inhabitants, showing signs of long-term stress, gill damage, and bacterial infections in the dead fish.
Scientists pieced together the puzzle, attributing the devastation to the marine heatwave of 2013, which acted as a catalyst for the growth of harmful algal blooms in the region.
These blooms suffocated the marine life, leading to the tragic loss of fish and other species along the Southern Australian coastline. This event demonstrated the severe impact of marine heat waves on marine life.
The 2013 disaster raised a critical question— Can marine heatwaves lead to mass extinctions? Understanding and addressing these effects is vital for the future health of our oceans, as it will help us develop strategies to mitigate these impacts, preserve marine biodiversity, and ensure the resilience of marine ecosystems in the face of a changing climate.
What is Marine Heat Waves?

The term “marine heatwave” (MHW) was first coined in 2011 following an unprecedented warming event that swept across Western Australia, triggering alarms among conservationists and environmental scientists.
This event marked a pivotal moment in our understanding of oceanic phenomena, as it highlighted the need for a clear definition and characterization of these extremely warm water episodes.
MHWs are prolonged periods of anomalously warm water at a specific location, distinguished by temperatures that exceed either fixed, seasonally varying, or cumulative thresholds.
According to the definition, a warming event lasting a minimum of five consecutive days qualifies as a marine heatwave, with the intensity determined by the magnitude of the temperature anomaly above the normal for that location and time of year.
The characteristics of MHWs, such as duration, intensity, location, and depth of ocean warming, are crucial in determining their impacts on marine ecosystems. MHWs can cover areas ranging from 500 to 2,000 kilometers and can persist for weeks to years, posing significant challenges to marine life and ecosystems.
Prolonged and intense MHWs can have devastating consequences, leading to mass coral bleaching, significant declines in kelp forests and seagrass meadows, and substantial biodiversity losses. These ecological impacts extend to socioeconomic realms, resulting in losses in fisheries income, erosion of essential ecosystem services, mass mortalities of iconic species, and stakeholder conflicts.
Research has shown that MHWs can be driven by a combination of oceanic and atmospheric processes, including changes in ocean currents, temporary weakening of winds, and anthropogenic warming.
The impacts of MHWs can be location-, species-, and process-specific, highlighting the need for a nuanced understanding of these events and their effects on different ecosystems and communities.
The frequency and duration of MHWs have increased significantly over the past century, with a doubling of events since 1982 and a 50 percent increase in the total number of days with MHWs globally.
This trend is expected to continue, with climate change projected to lead to more frequent, longer-lasting, and more intense MHWs in the future.
The 2011 marine heatwave in Western Australia highlighted the crucial need for a standardised approach to defining and characterising these heatwaves. By clearly defining the parameters of these extreme warm water events, researchers can improve their understanding of the factors that drive marine heat waves, enhance predictive capabilities, and assess the significant impacts on marine ecosystems.
This knowledge is essential for developing effective adaptation and mitigation strategies to safeguard the health and resilience of our oceans in the face of a rapidly changing climate.
Effects of MHWs
The MHWs can drastically alter marine ecosystems, triggering events such as mass coral bleaching, the decline of kelp forests, and significant biodiversity losses. However, MHWs rarely occur in isolation. They often coincide with other stressors, such as increased turbidity, desiccation stress, harmful algal blooms, and anoxia.
These stressors create a complex web of interactions, intensifying the overall impact on marine species and ecosystems. This interconnected web of challenges poses severe threats to marine species and the overall health of our oceans.
Physiological processes governing the performance of an organism
High temperatures can have a significant impact on the physiological processes governing the performance of an organism. The consequences of MHWs can range from sublethal to lethal. A change in temperature influences fundamental biological functions such as photosynthesis, respiration, growth, reproduction, phenology, and survival of species.
As temperatures rise, organisms must utilize more energy to regulate their internal environment and cope with the altered conditions. This increased energy demand can lead to an energy deficit, particularly during intense MHWs, negatively affecting overall performance.
In response, some species opt to relocate or migrate to cooler waters, reducing local population densities. When relocation isn’t an option, species may resort to compensatory mechanisms to mitigate the energy deficit.
This may involve increased feeding habits, decreasing growth rates, or sacrificing reproductive efforts. The decline in energy availability can impair neuromuscular and physiological functions, jeopardizing individual survival.
MHWs can trigger mass mortality events among fish populations in the wild and aquaculture. These events are often associated with factors like harmful algal blooms, deoxygenation, and disease outbreaks exacerbated by elevated temperatures.
Fish species with narrow thermal tolerance are particularly vulnerable to the effects of MHWs. For instance, in the Red Sea, 40 species of coral fish succumbed to thermal stress and bacterial infections during a 2017 MHW.
In Chile, MHW-induced harmful algal blooms, dubbed Godzilla red tide events, killed 100,000 tons of coho salmon and trout. The notorious Blob events in 2014 and 2016 caused a drastic decline in the Pacific Cod population, prompting fishery closures.
In South Australia, 39 fish kill events were reported in 2013, with an estimate of about 100 – 2000 fish dying per km. Gill lesions were found in the dead fish. Laboratory tests showed the cause of death to be bacterial infection.
An interesting behaviour of trout during an MHW in the Coral Sea in 2016 was observed. The catchability of coral trout in the area significantly increased. Scientists attributed this behaviour to the fish being more active in feeding, making fish-catching baits more attractive to trout.
This is discussed in the previous section, as well as how increased temperature alters species’ feeding habits. Conversely, this increased catchability could have negative consequences, potentially leading to overfishing and a decline in the trout population.
Marine Forests
Marine forests, including kelp and seagrass ecosystems, are vital components of coastal environments, supporting diverse marine life. These underwater forests play essential roles in maintaining the health of marine ecosystems.
They provide habitat and food for numerous species, help in carbon sequestration, offer coastal protection by stabilizing sediments, and contribute to nutrient cycling. However, marine heatwaves can devastate these sensitive ecosystems, leading to cascading effects throughout the marine environment.
Damaging Kelp Forests
MHWs can cause significant damage to kelp forests, resulting in habitat loss and shifts in species distribution and behaviour. In Baja, California, the MHW events of 2014 and 2016 destroyed a large portion of the region’s kelp forests.
This catastrophic loss disrupted the entire ecosystem, causing substantial shifts in habitat structure and species behaviour. Even more alarming, the Bull kelp species in New Zealand became regionally extinct during the 2017-18 MHW in the Tasman Sea.
Impacts on Seagrass Meadows
Seagrass meadows, another critical component of marine ecosystems, are also heavily impacted by MHWs. In the Mediterranean, the combined effects of MHWs and continuous sea warming have reduced Posidonia oceanica seagrass meadows. This habitat shift has allowed non-native species to thrive, altering these ecosystems’ biodiversity and carbon capture capacity.
The most well-documented case occurred during the 2011 MHW in Western Australia, where a staggering 1,300 square kilometers of seagrass were decimated. This loss threatened the survival of numerous marine species, including sea snakes, dugongs, bottlenose dolphins, and green turtles, which rely on these habitats for food, shelter, and breeding grounds.
The impact of MHWs extends beyond the immediate destruction of marine habitats. In Western Australia, the 2011 MHW also led to the loss of 100 kilometers of kelp and fucoid forests.
A decade later, the affected areas’ vegetation, fish, and invertebrate communities struggle to recover. The loss of these “marine forests” disrupts biodiversity and compromises essential ecosystem services such as carbon sequestration, coastal protection, and nutrient cycling.
Coral Reefs bleaching

Coral reefs are among the most precious and biodiverse ecosystems on Earth, providing habitat for numerous marine species and supporting the livelihoods of millions of people worldwide. However, these vital ecosystems are severely threatened by the impacts of MHWs.
One of the most notable impacts of MHWs on coral reefs is coral bleaching. This phenomenon occurs when corals lose their vibrant colours and vital symbiotic algae, ultimately leading to their death.
The first reported case of coral bleaching dates back to 1998; since then, these events have become more severe and widespread. In 2014 and 2017, more than half of the world’s coral reefs were affected by bleaching events, highlighting the global scale of this ecological crisis.
The loss of reef habitat and structural integrity directly impacts the diversity of coral reef ecosystems and the species that rely on them. Major bleaching events, such as those experienced in the Great Barrier Reef in 2016, 2017, and 2020, have significantly declined coral-eating and herbivorous fish populations.
Concurrently, there has been an increase in plankton-eating fish and shifts in invertebrate communities, indicating profound changes in the ecosystem’s balance and functionality.
In addition to direct mortality, MHWs can also affect corals’ reproductive and growth capacity, leading to a chain of negative impacts on associated biodiversity.
Reduced reproductive and impaired growth rates can hinder the recovery and resilience of coral reef ecosystems, exacerbating the long-term consequences of MHWs.
Impacts on Other Species

In addition to impacting fish and marine vegetation, MHWs also have severe consequences for sessile invertebrates like scallops, mussels, and barnacles. For example, the 2011 MHW in Western Australia significantly declined scallop and blue swimmer crab populations, leading to fisheries closures lasting between 18 months to 5 years. These closures impact commercial fisheries and disrupt local ecosystems and traditional fishing communities.
Furthermore, between 1979 and 2020, approximately 2300 mass mortality events affecting around 90 types of benthic species, including corals, oysters, and mussels, were recorded globally, with many attributed to ocean warming and the associated MHWs.
Additionally, the 1998 El Niño event led to mass mortality of Galapagos sea lions and king penguins, further highlighting the wide-ranging impacts of MHWs on marine ecosystems and species diversity.
Ecosystem services, the benefits healthy ecosystems provide to humans, encompass provisioning, cultural, regulating, and supporting services. These services are categorized into four types: provisioning, regulating, cultural, and supporting services.
Provisioning services
Provisioning services involve extracting natural goods, such as food, wood, and medicinal herbs. MHWs can adversely affect ecosystems, leading to losses in fisheries income, erosion of essential ecosystem services, and mass mortalities of iconic species. For example, the 2016 MHW in the southern Pacific led to the largest farm fish mortality event ever recorded.
Two Harmful Algal bloom events in Chile, the Godzilla red tide events, resulted in the mortality of 100,000 metric tons of coho salmon and trou, corresponding to $800 million in losses, cost of 4500 jobs, and a 50 percent increase in the cost of exported salmon to the US. Similarly, the 2012 MHW caused a $38 million loss in the lobster industry due to early inshore migration and sudden availability.
Cultural Services
Cultural services encompass non-material benefits provided by ecosystems, such as cultural development, recreational activities, spiritual enrichment, and aesthetic values. MHWs can significantly impact cultural services, leading to losses in tourism revenue and recreational activities. For instance, the 2010 MHW in southeast Asian seas caused $49 to $74 million in losses in the tourism sector due to coral bleaching and mass mortality.
Regulating services
Regulating services involve the benefits derived from natural processes that help moderate environmental conditions and phenomena, such as climate regulation, disease control, water purification, nutrient cycling, carbon capture, and flood and storm protection.
MHWs can disrupt these regulating services, leading to ecosystem functioning and biodiversity changes. For example, the 2011 MHW in western Australia destroyed seagrass meadows, releasing 2-9 billion kg of CO2 into the atmosphere for three years, resulting in significant economic losses.
Supporting services
Supporting services provide biogenic structures for habitat for many species. MHWs can significantly impact supporting services, leading to ecosystem structure and function changes.
For instance, between 1998 and 2016, MHWs in the Indian Ocean destroyed more than 70 percent of corals, leading to habitat loss and a shift in the foundation species and ecosystem services. While some coral reefs recovered, others underwent regime shifts, altering the ecosystem’s foundation species and habitat services.
Is all is lost?
Marine heatwaves significantly threaten marine ecosystems, impacting biodiversity, fisheries, and coastal communities. However, all hope is not lost. Comprehensive research and innovative strategies are being developed to understand, predict, and mitigate the impacts of MHWs, safeguarding marine environments and human well-being.
Scientists are utilizing observational data from both natural events and controlled experiments to assess the impacts of MHWs. Mesocosm systems, which simulate natural environments under controlled conditions, allow for studying multiple species and community-level experiments, bridging the gap between field surveys and laboratory studies.
Sophisticated early warning systems are being developed, integrating real-time monitoring using in situ sensors and satellite data. These systems provide crucial information on the likelihood, intensity, frequency, duration, and potential impacts of MHWs. Near forecast systems offer predictions 5 to 7 days in advance, while seasonal forecasts provide longer-term predictions.
Historical observations and experimental data are combined to understand the effects of MHWs on ecosystems better. Models and systems can also predict socioeconomic outcomes, aiding in developing adaptive management strategies for fisheries-related communities.
Management techniques are being implemented to mitigate the impacts of MHWs. These strategies include changing fishing practices, introducing catch limits, targeting specific species, and implementing measures like artificial cooling and shading in fish farms. Creating seasonally protected areas can also help safeguard vulnerable species from the effects of MHWs.
Researchers are developing innovative techniques such as early-stage heat exposure, which exposes young individuals of species to heat during early development to enhance heat resistance. Additionally, breeding programs aim to identify and propagate heat-tolerant strains of species for fisheries.
Moreover, despite these challenges, marine organisms also exhibit remarkable resilience and adaptive strategies in the face of MHWs. Behavioural changes, such as seeking refuge in cooler habitats or adjusting activity patterns, allow species to cope with rising temperatures. Cellular mechanisms help protect vital functions and prevent damage to macromolecular components, albeit at the cost of reduced growth and reproductive success.
Reducing greenhouse gas emissions from human activities remains a critical challenge in tackling MHWs. Addressing the root cause of climate change is essential for mitigating the frequency and intensity of MHWs, protecting marine ecosystems, and ensuring the sustainability of coastal communities for future generations.
We can work towards a more resilient future for our oceans through continued research, innovative management, and global climate action.
What needs to be done?
Marine heatwaves pose a significant threat to marine ecosystems, potentially triggering regional extinctions and, if left unchecked, even global mass extinctions. The compound effects of MHWs, combined with other stressors like ocean acidification, overfishing, and habitat destruction, can create cascading impacts that push vulnerable species to the brink of extinction.
While some marine species exhibit resilience and adaptive strategies in the face of rising temperatures, the increasing frequency, intensity, and duration of MHWs may exceed their ability to cope.
A sudden, extreme event could act as a tipping point, initiating a catastrophic chain reaction that overwhelms the resilience of marine life. The short duration of these events may not allow sufficient time for species to evolve or adapt, leading to mass mortality and potential extinction.
Scientific research plays a crucial role in understanding and mitigating the impacts of MHWs on marine ecosystems. Ongoing efforts to monitor and forecast these events, assess their ecological and socioeconomic consequences, and develop adaptation strategies are essential for preserving marine biodiversity.
However, the most critical factor in mitigating the threat of MHWs and preventing mass extinctions is addressing the root cause of climate change. Global cooperation and concerted action to tackle climate change are essential for preserving marine biodiversity and ensuring the resilience of marine ecosystems in the face of a rapidly changing climate.
The population of the world is around 8 billion and is constantly growing. With the advent of time, technologies like the Internet of Things (IoT), edge computing, and Artificial Intelligence (AI) have become a part of our daily lives. A lot of data is generated every second. Every time our interaction with the phone creates data.
IDC (Internet Data Center) states we will have 175 Zettabytes of data by 2025. This data is so huge that if we have DVDs to store this data, the stack of DVDs would be large enough to wrap the earth 222 times. Recent research has demonstrated the capability of using DNA molecules to store genetic information, encode digital information, and do useful computations.

What is DNA?
DNA is short for deoxyribonucleic acid. It is basically a hereditary material consisting of a group of molecules carrying genetic information about a living organism. We can also call it the fingerprint of a living organism. It’s made up of long chains of molecules called nucleotides, which contain the instructions for an organism’s growth, development, functioning, and reproduction.
Each nucleotide is composed of one of four nucleobases (adenine [A], thymine [T], cytosine [C], or guanine [G]) and a sugar-phosphate backbone. DNA encodes genetic information like data can be encoded onto electronic-based storage devices. That’s why we called it the natural storage device.
Ages of Data
In the early history of humankind, the only way of storing data and conveying information was by painting and carving. Lascaux Cave Paintings, a collection of paintings (approximately 20,000 years old) discovered in caves of the Dordogne region of southwestern France. These paintings include animals such as horses, bulls, and deer, as well as abstract symbols that give insights into the lives and beliefs of early humans, possibly serving as a form of communication or storytelling within their community. Sumerian Cuneiform Tablets are one of the oldest forms of writing (around 3500 BCE).
They were used to record a variety of information, such as temple activities, trade, stories, and myths. By this time, humans had developed a lot of storage devices like Magnetic Tape, Hard Disk drives, SSDs, USB, NVMe (Non-Volatile Media Express), etc. After many developments, we are able to store 4TB of data on a single SD card, which is so compact that we can handle it with our fingertips. Now, we are in the age of big data. So, the world is searching for a new mode of data storage devices. And one possible answer to their questions is “DNA.”
“DNA is really good at storing information because it’s much more compact (3-to-6 orders of magnitude) and more reliable than electronic memory. It can hold a lot of data and lasts much longer without getting damaged”, said researchers at RIT (Rochester Institute of Technology).

DNA as a Storage Device
“We are in the age where vast data is generated every second and needs to be stored somewhere. The conventional way of storing data is in data centers. Building more data centers isn’t the optimal solution. Each data center consumes power equivalent to a city block, making it unsustainable to maintain, construct, and operate traditional data centers at an increasing rate,” study co-author Amlan Ganguly, head of the Department of Computer Engineering at the Rochester Institute of Technology (RIT), said in a statement.
Companies such asMicrosoft have also recognized DNA as one candidate to manage and store skyrocketing amounts of data. DNA storage is also much more expensive to manufacture. The cost of chemically synthesizing DNA is still high at $3,500 per 1 megabyte (MB) of information. The capacity of the DNA to store data is 200 petabytes (PB) per gram. The latest research has revealed that just four grams of DNA could store the annual global digital information.
DNA as a Computation Device
DNA computing is an exciting technology in computing. Instead of silicon-based electronic circuits, it utilizes molecular reaction techniques to compute DNA molecules. Scientists (Arnav Solanki et al.) have created a new Biocomputing chip that makes calculations using a DNA substrate.
This is a platform or surface on which instructions are read and used to perform tasks, kind of like a special type of paper on which instructions are written, including mathematical operations indispensable to big data processing and artificial intelligence (AI) training.
Researchers (Arnav Solanki et al.) described the new Biocomputing platform in the journal PLOS One. DNA-based devices have previously been used to encode data on a small scale, but this prototype chip also uses DNA to process data.
Researchers (Seth Shipman et al.) have previously built DNA-based storage devices, encoding the DNA molecules of bacteria with a video of a horse in 2017. The comparative analysis outlined in a 2018 paper published in the journal 3Biotech revealed that data transfer rates on DNA-based storage platforms are considerably slower than those of conventional storage devices.
In the study, AmlanGanguly and his team explored techniques for manipulating DNA at the molecular level to replicate numerous functions analogous to those of computing, including sequencing (data reading) and synthesizing (data writing).
The encoded data on the DNA by nicking (cutting of DNA) strands at specific locations to represent the 1s and 0s of binary, and represented different calculations by using a network of microfluidic channels. This transfers fluids around an integrated circuit to perform functions as chemical reactions. DNA processing can also offer “unprecedented parallelism’, the ability of modern computer systems to perform multiple tasks simultaneously, said Amlan Ganguly in their paper.
DNA is now the best option in this era, where data storage is a big problem due to its large storage capacity. DNA is incredibly good at storing information and can last a really long time. But now it’s not only about storage; scientists are exploring how to use DNA for computations. They have built Microfluidic devices that can store data and perform useful computations. This new Microfluidic device is a proof-of-concept, but the scientists hope that by scaling the device, it can one day be used to train AI systems.
Of course, there are still some hurdles to overcome, like cost and performance optimization, but possibilities are endless. Imagine a future where all our data is stored in tiny DNA molecules, and computers solve complex problems using biology instead of silicon chips. It’s a wild idea, but it just might be the key to unlocking a whole new world of technology.

Have you ever wondered why it seems more accessible for the average person to participate in political discussions, yet basic scientific concepts like hyperglycemia or the consequences of burning trees remain somewhat mysterious?
Why is the average person only striving to get money but not interested in learning? Why is learning about science and getting knowledge limited to a specific age group? Why do we confine knowledge about science to textbooks and classrooms while political information is readily accessible on social media and TV?
The need of the hour is to make scientific knowledge as prevalent and accessible as discussions about politics.
Give man money, and you’ll feed one person, but if you give a man knowledge, you’ll feed a family. – Dr. Muhammad Mustafa
Effective communication can help demystify complex health issues, providing the public with reliable information that empowers them to make informed decisions [1]. It involves not just the transmission of data but also ensuring that the information is relatable, understandable, and actionable. This is crucial in an age where misinformation can spread rapidly and severely affect public health. As John Young said,
In the face of climate change and persistent healthcare challenges, effective communication of scientific knowledge emerges as a beacon of hope. The need for urgent action has never been more apparent when it comes to environmental issues such as climate change, pollution, and deforestation. However, environmental science is often complex and challenging for the general public to understand.
“Speak on behalf of Mother Nature before we can’t,” –Dr. Muhammad Mustafa
Effective science communication
Science communication aims to clarify how various processes work, such as how a virus infects a person or the importance of new cancer treatments for healthcare professionals and patients[2]. It strives to present this information in a clear, relatable, and meaningful way.
Similarly, health communication focuses on presenting scientific information in a way that resonates with audiences, offering practical steps they can take to improve their health or prevent disease. It often goes beyond cellular interactions to apply scientific findings to entire populations, making the science applicable and beneficial to everyday life and public health efforts.

Science communicators use different channels like documentaries, articles, and social media campaigns to translate scientific research into gripping narratives that resonate with people of various ages and backgrounds[3]. Promoting scientific literacy and encouraging informed decision-making can be accomplished by education systems, media outlets, and community organizations[2]
Science communicators and some notable organizations, like the Khwarizmi Science Society, play a crucial role in simplifying this complexity. By organizing the Lahore Science Mela in the past several years, they have played a significant role in conveying information in a way that empowers individuals to make informed decisions about their impact on the environment.
Through initiatives like workshops, public lectures, and educational outreach programs, a deeper understanding of environmental issues can promote sustainable practices.
Science festivals can act as social glue, Dr. Sabieh Anwar.
By amplifying the voices of scientists and providing accessible platforms for dialogue, these organizations contribute significantly to raising awareness and driving positive change for the environment and public health.
Science communication makes environmental issues more relatable and concrete, encouraging people to take action and feel a shared sense of responsibility towards the planet.
Healthcare communication
Healthcare is another area where science communication plays a crucial role. Effective communication is essential in raising awareness and shaping behavior, from combating infectious diseases to promoting healthy lifestyles. One of the primary aims of healthcare communication is to give people the tools to take charge of their health and well-being[3].
Science communicators empower individuals to make informed decisions about their health by translating complex medical jargon into accessible language and providing evidence-based information. Science communication offers people with the knowledge they need to prevent diseases, manage chronic conditions, and seek appropriate medical care through public health campaigns, educational resources, or online platforms.
Fostering scientific literacy
Fostering a culture of science literacy and critical thinking is fundamental for building resilience against misinformation and pseudoscience. Science communicators employ various strategies to spread environmental and healthcare awareness effectively.
They often use storytelling to convey complex scientific concepts in relatable and engaging ways, capturing the audience’s attention and evoking empathy.
Additionally, visuals such as infographics, videos, and interactive media enhance comprehension and make abstract ideas more tangible [4]. Collaboration with scientists, policymakers, and community organizations amplifies the reach and impact of communication efforts.
Interactive engagement through workshops, citizen science projects, and online forums fosters participation and facilitates two-way communication.
Transparency and trustworthiness are paramount, with communicators being transparent about scientific limitations and sources of information. They empower individuals to take action by providing practical tips and resources, inspiring a sense of agency.
By translating complex scientific concepts into accessible information, fostering dialogue, and empowering individuals, science communication drives positive change and contributes to a healthier, more sustainable world. In the 21st century, investing in effective science communication is not just an option—it’s a necessity.

Several developed countries allocate special funds for research in their annual budget, due to which scientific research has accelerated in recent years. However, an international scandal reveals that thousands of bogus research papers are being published in science journals, and the situation worsens yearly.
Meanwhile, plagiarism in peer review remained surprisingly overlooked despite a notable rise in such cases in recent years. According to a study published in Nature, many published scientific papers worldwide are reviewed and retracted yearly, but in 2023, more than ten thousand such papers were retracted.
Another study published in Springer revealed that an in-depth analysis of fifty suspected scientific papers had detected plagiarised content.
The debate sparked after the Standford University Scandal!
In July 2023, a global debate kick-started when Marc Tessier-Lavigne [The then] President of Standford Univeristy announced his resignation after an independent review of his research. The investigations found significant flaws in the studies he supervised a decade ago.
Although Tessier Lavigne was cleared of accusations of scientific fraud and misconduct, the review said his work had several problems and fell below customary standards of scientific rigor.
Tessier-Lavigne said, “I expect there may be an ongoing discussion about the report and its conclusions, at least in the near term, which could lead to debate about my ability to lead the university into the new academic year.”
Theo Baker, the investigative editor of the Stanford University newspaper “Stanford Daily,” was awarded the “George Polk Journalism Award” for exposing this mishandling in scientific papers. After the revelation of this scandal, the voices against fraud in scientific publications got another spark worldwide.
AI helps Scientists to trick reviewers
Richard Van Noorden, editor of Nature, says that scientific papers can be manipulated in several ways. For example, they create fake research data with the help of artificial intelligence and chatbots, specifically ChatGPT, taking data from Google, duplicating images and troubled phrases, etc.
He further points out that in peer review fraud, scientists help each other pass research data without analysis. Most of such papers have text or content stolen from other research papers. Several editors and journals manipulated the metadata of accepted papers to increase citations of specific scholars and journals.
While talking to the Guardian, Professor Dorothy Bishop of Oxford University says that “the extent of fraudulent papers publication is creating serious problems for science. Building a cumulative approach to a subject in many fields is becoming arduous because we lack a solid foundation of trustworthy findings.”
“The startling rise in the publication of sham science papers has its roots in China, where young doctors and scientists seeking promotion must have published scientific papers. This demand has given rise to scientific fraud, and shadow organizations known as “paper mills” now supply fabricated papers for journal publication.”
“The practice then spread to India, Iran, Pakistan, Russia, Saudi Arabia, eastern Europe, and several other countries with paper mills selling fabricated papers to science journals. There is a growing demand for such papers as young scientists are more eager to boost their careers in international universities by claiming false research experience.”
“Journal editors have sometimes been bribed to accept articles, while paper mills have established their agents as guest editors who allow reams of falsified work to be published”, she argued.

Spotting fraudulent scientific papers!
Even scientific research cannot spare from the increasing influence of digital media worldwide. A new trend in scientific communities is to send out a press release to media outlets before publishing their research papers. In these press releases, the researchers over-exaggerate as a breakthrough research, but later, it turns out to be bogus.
Elisabeth Bik, a Science Integrity consultant — says that the growing trend of fake scientific research is a cause for serious concern for scientists and researchers worldwide. To address this problem, some scientists have formed non-profit groups revealing such bogus research. There are also websites like “PeerPub” and “Retraction Watch“—these sites have complete data of all the retracted science papers.
Lonni Besançon, a researcher at Columbia University, expresses her joy and says— “It is good news that more than ten thousand research papers were retracted in 2023. This comes after a big year debating on this topic and the topic of finding fraudulent practices.”
“Of course, some researchers like me may always see the glass half empty — and I would still argue that probably many more papers should have been retracted and that, as I have lamented several times, the process of correcting the scientific literature is too slow, too opaque, and too bureaucratic. While at the same time not protecting, funding, or rewarding the hardworking sleuth behind the work.”
“Most of the sleuthing work takes place despite, rather than thanks to, the present publication and editorial system. She argues that the data or metadata to facilitate investigations is often not published or available”.
Mikolaj Piniewski, the study’s lead author published in the Springer, is affiliated with the Warsaw University of Life Sciences. He explains that his team used AI to highlight manipulation in 50 research papers. AI can detect patterns in papers that should not be there in principle and identify plagiarized content within the paper and original sources.
He further elucidates that his team of researchers asked the authors of the fifty suspected papers to publish their complete data. Later on, an Excel sheet of data was analyzed with the help of AI. The analysis found that most data had been repeatedly copied, pasted, and manipulated.

The Nerve-Breaking situation for Pakistan!
In December 2023, a Nature analysis revealed that among large research-producing nations, Saudi Arabia, Pakistan, Russia, and China have had the highest retraction rates over the past decades. Pakistan stands as the second nation with the highest research retraction rate worldwide.
Dr. Nayyar Alam, a senior researcher and geologist, expresses his concern and says, “Publishing scientific papers is significant for students and scientists. Many international universities and research institutions have for admission and the progress of scientists that includes several published research papers in reputed science journals.”
Moreover, he points out the main reasons for this downfall in scientific research— firstly, a shortage of international-level research in Pakistan’s universities is due to insufficient budget. The Higher Education Commission of Pakistan is running short of funds to sponsor research projects. At the same time, our laboratories are deficient in modern equipment and facilities.
A third reason is the absence of science writing skills in English. Our students can hardly write science essays due to mere writing training in academic institutions. The students and researchers prefer fake resources like paper mills to get admission to international universities. These papers are retracted after some time, and the situation is quite disturbing to hardworking researchers.
Like several other fields of life, corruption is creeping into the global scholarly journal publishing market. Ten of thousands of students and scientists are building their careers on the back of this tidal wave of fraudulent papers. But every now and then— they have to face the harsh reality of life, as the world is now more aware of such false practices.
Several efforts are underway to ensure the highest research standards worldwide. Organizations sponsoring or funding research demand scientists publish all of their data to be thoroughly scrutinized. Science journals that publish new studies have already started screening suspected data— everyone involved in the process, including funding, production, and publication, is on ALERT now!
Fusion-powered stars stand as celestial beacons in the vast fabric of the universe, illuminating the blackness of space with their incandescent brilliance. They project a fascinating alchemy at their heart, in which the simplest atom, hydrogen, evolves into heavier elements via a chain reaction known as nuclear fusion.
The Origin of Dark Star Idea
The concept of dark stars originated through a series of discussions between Freese and Doug Spolyar. Mr. Spolyar is a former University of California, Santa Cruz graduate student.
Pondering over the influence of dark matter on the first stars that emerged in the universe, they reached out to Paolo Gondol. He is an astrophysicist at the University of Utah and subsequently joined the team.
After years of development and exploration, they published their initial paper on this groundbreaking theory in the journal Physical Review Letters in 2008.
The Enigma of Dark Stars
These three objects (JADES-GS-z13-0, JADES-GS-z12-0, and JADES-GS-z11-0) were initially identified as galaxies in December 2022 by the JWST Advanced Deep Extragalactic Survey (JADES). Now, a team including Katherine Freese at The University of Texas at Austin speculates they might actually be “dark stars,” theoretical objects much bigger and brighter than our sun, powered by particles of dark matter annihilating.

Astrophysicists at the University of Texas at Austin said on July 14, 2023, that they’ve now identified three bright objects that might be “dark stars.” Until now, “dark stars” have only existed as theoretical creations in the domains of mathematical models and scientific ideas. The term ‘Dark’ does not refer to the luminosity of the star but todark matter as the power source at its core, rather than the typical nuclear fusion reactions that power ordinary stars.
Recent findings were published in the Proceedings of the National Academy of Sciences. The research revealed three mysterious celestial objects that, Originally identified as galaxies in December 2022 by the JWST Advanced Deep Extragalactic Survey (JADES), the three candidate dark stars, named JADES-GS-z13-0, JADES-GS-z12-0, and JADES-GS-z11-0, have now become subjects of intense scientific inquiry.
“It’s more likely that something within the standard model needs tuning because proposing something entirely new, as we did, is always less probable,” Freese said. “But if some of these objects that look like early galaxies are actually dark stars, the simulations of galaxy formation agree better with observations.”.
While this discovery does not prove their existence, it has sparked renewed interest among scientists and astronomers to investigate this cosmic mystery further.
“Discovering a new type of star is pretty interesting all by itself, but discovering it’s dark matter that’s powering this — that would be huge,” said Freese, director of the Weinberg Institute for Theoretical Physics and the Jeff and Gail Kodosky Endowed Chair in Physics at UT Austin.
You see slightly varying estimates for the percentage of dark matter in our universe. But, according to Fig. Modern theorists, there’s vastly more dark matter than ordinary matter in our universe.

The Dark Matter Enigma and Model for Dark Stars
Now, let’s drive into the heart of the mystery – dark matter. It’s arguably one of the most compelling mysteries in contemporary astrophysics, and it’s no wonder it has both seasoned physicists and curious minds on the edge of their seats. Unlike ordinary matter, dark matter does not emit, absorb, or reflect light. It’s invisible, making it notoriously difficult to detect directly.
The model by Freese and her colleagues assumes that dark stars form in clouds made mostly of hydrogen, with dark matter contributing just 0.1% of the mass. When two dark matter particles collide, they can annihilate each other, releasing photons, electrons, and other particles. Most of these by-products stay in the cloud, depositing heat into its gas and causing it to glow like a normal star.
“Dark stars are a theoretically intriguing idea,” says Julian Muñoz, a cosmologist at the University of Texas at Austin who was not involved in the current work. “Self-annihilations are a fairly generic signature of many dark matter models.” They are a central feature in one popular model, in which dark matter comprises weakly interacting massive particles or WIMPs.
Some Important Results Deduced from the Existence of Dark Stars
Let’s go on to the results, where things get even more intriguing. This is more than simply physics; it’s a cosmic narrative that has the potential to alter our fundamental understanding of the cosmos.
Early Universe Dynamics: But hold on, there’s more. Dark stars may have evolved in the very early stages of the universe when conditions were significantly different than they are now.
Supermassive Black Holes’ Seed: We’ve arrived at the climax. If dark stars exist, they have the potential to shed light on the genesis and expansion of supermassive black holes (SMBHs). Dark stars may act as cosmic seeds from which these enormous black holes sprout, offering light on the earliest conditions that lead to the formation of SMBHs.

“Success in creating AI would be the biggest event in human history. Unfortunately, it might also be the last unless we learn how to avoid the risks.” ~Stephen Hawking
The rise of AI is like watching a sci-fi movie unfold, except we’re all trying to figure out if AI will become our helper or an unforeseen Master. I am sure you’ve seen many things on the wonders of Artificial Intelligence but where there is light, there is also shadow. Artificial Intelligence holds unbelievable promise for improving our lives in vast measures, it also presents challenges and threats that we must address.
Ever wondered what exactly artificial intelligence is and why everyone wants to indulge in it? What is the hype around it, and is it really a threat to humankind? Let’s dive in.
Well, Artificial Intelligence has been tossed around for decades, but it wasn’t until recently that it started gaining attention.
The term “artificial intelligence” was officially used at Dartmouth College, where researchers discussed the probability of creating machines that could mimic human intelligence. In today’s day and age, it isn’t a mere term or concept but an everyday reality for us. AI invades various surfaces of society, reshaping how we work, communicate, and interact with technology.
The appeal of AI lies in its ability to solve problems in previously impossible or impractical ways. AI can automate repetitive tasks, saving time and effort. It’s like having a clever robot buddy that can learn and make your life efficient.
Speaking of robots, AI is far more progressed than just GPT-4. Have you met with the humanoid robot Ameca, which acts as a translator using the OpenAI’s ChatGPT bot, that could potentially extinct human translators? [2]
A well-read research paper that looks further into this is “The Malicious Use of Artificial Intelligence: Forecasting, Prevention, and Mitigation,” published in February 2018. [3] This paper is authored by researchers from the Future of Humanity Institute. It is known for being the Center for the Study of Existential Risk, OpenAI, and others.
It explores the possible negative impacts of Artificial Intelligence if used wickedly. Highlighting situations where AI could be exploited for cyberattacks, disinformation campaigns, and autonomous weapons systems raises significant ethical and security concerns. Here is a series of advancements in Generative Adversarial Networks (GANs) that have created synthetic faces that are becoming increasingly indistinguishable from real ones.

One of the most prominent downsides of AI is mentioned as a personalized attack to extract sensitive information or money from individuals. The rise of facial recognition technology has ushered in a new era of possibilities: an AI tool called Synthesia. This tool can generate human-like voices and AI avatars that could be used in several positive ways, such as making a marketing campaign, making content online, or training videos. However, this AI tool has sparked many concerns about privacy and cybersecurity.
As mentioned in the paper, a phishing attack refers to a cybercrime tactic where individuals or organizations attempt to deceive users into disclosing sensitive information, such as usernames, passwords, credit card details, or other personal data. It also addresses Political, Physical, and Digital Security risks like an individual’s online information used for impersonation and milking their real contacts; cybercriminals can use AI techniques to process payment or ransomware victims.
The research paper discusses the importance of active measures to mitigate the risks associated with the cruel use of AI and the need for disciplinary cooperation among researchers, policymakers, and industry stakeholders to develop safeguards and regulations that ensure AI technologies are deployed responsibly.
A recent article shed light on the unstoppable surge of Generative AI, which showed that approximately 77 percent of devices include AI [4] in some form, like opening your phone with the face ID or ads on social media, to famous digital assistants like SIRI or ALEXA. However, this personalized AI experience raises dual concerns. While 57 percent fear AI may replace humans, [5] 51 percent lack trust in companies to safeguard their data, leading to worries about privacy, security, misinformation, and job insecurities.
Now the lingering question: could Artificial Intelligence defy its creators and dominate humanity, as depicted in movies?
Well, not exactly. The maintenance, power supply, and programming are essential for Generative AI, Robots, and GANs, and all rely on human involvement. Also, Governments, corporations, and individuals each play a role in the development, deployment, and regulation of any form of new research or development.
Corporations innovate through research and development while also obeying regulatory requirements and ethical guidelines. So, it’s safe to say there’s not much to worry about besides some job insecurities. [6]
The strength of Artificial Intelligence depicted in movies is mainly dramatized for entertainment purposes. Whereas Artificial Intelligence might have advanced significantly in recent years, it still operates within the boundaries of its programming and the limitations set by its creators. That said, it’s essential to recognize the potential risks associated with AI development, and these risks must be carefully managed through ethical guidelines and responsible development practices.
But why should we keep up with the advancement of artificial intelligence?
AI has a prominent position now, providing us with a further understanding of our intelligence. The growth of AI is crucial; learning and actively using AI tools is important not just to stay informed by the latest AI but also to form your own opinions on it and identify issues that could form risks towards security or privacy issues.
While challenges and doubts may be linked to the increase of AI, there’s also significant potential for positive impact and growth when approached with careful consideration and practical planning.
In the near future, its implications on society, economy, and governance are key for navigating responsibly and harnessing its potential for the betterment of humanity, and hopefully, stricter laws will be formed around its data storage and usage to safeguard the rights of AI’s users.
