Decoding Bennu: Groundbreaking 2024 research redefines life’s origin

Imagine holding a piece of history older than Earth itself, a fragment of the building blocks that shaped our solar system and, possibly, the origins of life. NASA’s OSIRIS-REx mission has done just that. This ambitious spacecraft returned with samples from asteroid Bennu in late 2023, and the subsequent research in 2024 has revealed profound insights into the universe’s ancient chemistry and our place within it.

OSIRIS-REx, an acronym for Origins, Spectral Interpretation, Resource Identification, and Security-Regolith Explorer, was designed to study Bennu, a near-Earth asteroid with an abundance of organic material. The mission launched in 2016, with the spacecraft reaching Bennu in 2018. Over two years, it meticulously mapped the asteroid, using advanced remote sensing technologies to understand its surface, composition, and geological features. The mission’s highlight came on October 20, 2020, when it successfully collected samples from Bennu’s surface and returned to Earth on September 24, 2023, landing in Utah.

Two days after a Touch-and-Go event (TAG) on the asteroid, the mission team received images that confirmed the spacecraft had collected at least 2 ounces (60 grams) of the asteroid’s surface material. Dr. Thomas Zurbuchen NASA’s associate administrator for science announced with delight, “We are so excited to see what appears to be an abundant sample that will inspire science for decades beyond this historic moment.”

Know about Bennu: A Time Capsule of the Early Solar System

Bennu is more than just a rock in space; it’s a pristine remnant of the solar system, preserved in its unaltered state for billions of years. Unlike Earth, where plate tectonics and weather have erased traces of early history, Bennu’s surface offers a rare glimpse into the chaotic era when planets formed. Scientists chose this asteroid because it is rich in carbon-based compounds, the essential ingredients for life as we know it. Its well-preserved regolith (loosely bound surface dust) could hold molecular clues to the origin of water and organic materials on Earth. Moreover, Bennu’s orbit—close enough to Earth for a feasible mission—made it an ideal candidate for sample return.

Why does it matter? Bennu’s material provides an unprecedented opportunity to analyze astromaterials in laboratories on Earth, bridging the gap between remote observations and tangible evidence. The mission enables scientists to study Bennu’s history, its role as a potential delivery system of organic compounds to Earth, and how space weathering has shaped its regolith. Such analyses promise to fuel discoveries for decades, shedding light on the origins of life and the dynamic processes that govern our solar system.

Asteroids and the Theory of Panspermia

These potential clues to the origin of life naturally lead to the broader question of how life itself may have spread across the Universe. This brings us to the fascinating concept of “panspermia”, the hypothesis that life exists throughout the Universe and is distributed by space dust, asteroids or comets. In simpler terms, panspermia suggests that the seeds of life may have been scattered throughout the cosmos, transported from one celestial body to another.

A series of astronomical observations conducted between 1980 and 2018 align with the theory of cometary panspermia. The key findings include (1) ultraviolet and infrared spectra of interstellar dust, (2) near and mid-infrared spectra of comets, (3) the discovery of an amino acid and degradation products associated with biology from material collected during the Stardust Mission in 2009, (4) jets from Comet Lovejoy that contain both sugar and ethyl alcohol, and (5) data from the Rosetta Mission.

Analyzing the returned sample will allow scientists to study the composition of these organic molecules in detail, potentially revealing whether they possess the chirality (a property of asymmetry in molecules) associated with terrestrial life. This could provide compelling evidence supporting the role of asteroids in delivering the ingredients for life on Earth, and possibly elsewhere in the universe.

The sample capsule pierced through Earth’s atmosphere and floated down gently into the rugged desert terrain of Utah. After years of careful planning, months of specialized training, and countless rehearsals, the NASA recovery team swooped in by helicopter to retrieve the capsule and its valuable contents. To keep it safe from Earth’s environment, the capsule stayed sealed until it was securely transported to a clean room for decontamination. Contrary to expectations, the initial findings were unexpected. No, there weren’t any alien tentacles creeping out from the sample.

After opening the lid, 70 grams of bonus sample containing dark grey rocks and dust outside the sample canister were revealed. To preserve its pure state, the whole operation had to be performed inside a nitrogen-purged glovebox—an enclosed box with built-in gloves that is constantly flooded with neutral nitrogen gas to ensure the sample does not react with other gases in Earth’s atmosphere, like oxygen or water vapor.

Three and a half months after the return capsule touched down on Earth, the curation team was finally able to access the material inside the canister. Another 51g of pristine Bennu material was revealed, and when combined with the bonus rocks and dust already collected, the total amounted to at least 121.6 g, more than twice what the mission had aimed to bring back to Earth.

This material was then cataloged and divided into smaller samples. Up to a quarter of the sample will be distributed to 233 scientists worldwide, who are part of the analysis team that will have the opportunity to study pieces of asteroid firsthand. The remaining 70 percent will be preserved at NASA’s Johnson Space Center for scientists who are not part of the mission team and for future generations to study.

Methods for Sample Analysis

The OSIRIS-REx team has prepared a 274-page document outlining 70 hypotheses to test and specifying the sample amounts down to the milligram. One of the techniques mentioned is spectroscopy, which enables researchers to identify the molecules and compounds that make up the sample. It will help them understand the composition of the asteroid Bennu.

Additionally, microscopy will be employed to reveal the sample’s structure on a small scale. Another important method is spectrometry, which can determine the ratio of isotopes in the sample. This means it can identify the amount of atoms of an element that has extra neutrons in its nucleus, making them heavier. Measuring the ratio of normal atoms to heavier isotopes is incredibly valuable, as it can provide insights into where in the solar system an object formed, whether it contains pre-solar material (material that existed before the sun formed), and how old the object is.

Key Discoveries from Bennu’s Samples

Carbon Abundance

Bennu’s samples revealed a substantial presence of carbon, making up about 4.5–4.7% by weight. This finding highlights the asteroid’s carbonaceous nature, similar to early solar system materials. Among the organic components found are nano globules and polycyclic aromatic hydrocarbons (PAHs), which have preserved their original characteristics without much thermal alteration.

Other elements found were presolar carbides and graphite, further supporting the idea that Bennu has remained largely unchanged since its formation in the protoplanetary disk. These discoveries affirm that Bennu acts as a time capsule, holding clues to the solar system’s earliest building blocks.

Water-Bearing Minerals

The samples showed a significant amount of hydrated minerals, especially phyllosilicates like serpentine and smectite, containing hydration levels of 0.84–0.95% by weight. Spectral analysis confirmed the presence of OH-/H2O and Mg-OH features, pointing to Bennu’s history of aqueous alteration. This hydration is consistent with Bennu’s classification as one of the more aqueously altered carbonaceous chondrites.

The interaction between the asteroid’s minerals and water likely is significant in forming other compounds, such as carbonates, magnetite, and iron sulfides. These hydrated minerals suggest that Bennu had a wet and dynamic past, potentially tied to the evolution of its parent body or its interactions with the protoplanetary disk.

A Surprising Discovery of Phosphates

One of the most unexpected findings was the detection of water-soluble phosphates, including Mg-phosphates and Ca-phosphates. These minerals, which had not been previously identified from spacecraft data, indicate a complex fluid chemistry that could have introduced unique chemical signatures into Bennu’s regolith. The Mg-phosphates, characterized by a nanoporous texture, may serve as important carriers of water and sodium in primitive asteroids, representing a new class of hydrated minerals.

Their composition and structure are similar to findings from asteroid Ryugu, suggesting shared processes in the early solar system. The presence of these phosphates hints at Bennu’s possible connection to a wetter parent body and underscores its importance in understanding the role of water in shaping both organic and inorganic materials in the solar system.

Bennu and Ryugu: A Comparative Exploration

Bennu and Ryugu, two carbon-rich near-Earth asteroids that were investigated by OSIRIS-REx and Hayabusa 2 missions respectively, have some very fascinating similarities that provide an insight into their common origins. Both asteroids have a shape reminiscent of a spinning top, which scientists believe is the result of fragments coming together after a larger parent body breaks apart in a cataclysmic event.

Their compositions are abundant in organic materials and water-bearing minerals, reinforcing their status as some of the most primitive bodies in our solar system. These shared traits suggest that Bennu and Ryugu likely came from the same disrupted parent asteroid in the asteroid belt, and they may have played a role in delivering essential prebiotic materials, like amino acids and nucleobases, to Earth.

Even though they may share a lineage, Bennu and Ryugu have taken different evolutionary routes. Ryugu shows lower levels of hydration, which points to either a greater loss of volatile substances or more intense thermal changes compared to Bennu.

Their surface features also reveal some key differences: Ryugu has a darker, rockier surface with less weathered regolith, while Bennu’s surface is smoother, featuring a blend of fine regolith and boulders. These distinctions might stem from variations in their exposure to solar radiation, thermal cycles, and impacts from micrometeorites.

The discovery of prebiotic molecules further emphasizes their shared background while also highlighting their unique histories. For example, samples from Ryugu showed uracil, a crucial RNA nucleobase, and nicotinic acid, with variations in concentrations across different sample sites possibly linked to exposure to cosmic rays. In contrast, Bennu’s organic content is yet to be revealed.

Looking Ahead: OSIRIS-APEX

The exploration of Bennu and Ryugu has opened new pathways for asteroid research with NASA’s OSIRIS-APEX mission set to investigate another asteroid, Apophis, during its close approach to Earth in 2029. Although we cannot collect regolith samples from Apophis as we did with Bennu, the OSIRIS mission will continue to use its advanced remote sensing suite to analyze the asteroid’s surface geology, which is incredibly powerful.

Concluding with the words of OSIRIS-REx principal investigator Dr. Dante Lauretta, “The bounty of carbon-rich material and the abundant presence of water-bearing clay minerals are just the tip of the cosmic iceberg. These discoveries, made possible through years of dedicated collaboration and cutting-edge science, propel us on a journey to understand not only our celestial neighborhood but also the potential for life’s beginnings. With each revelation from Bennu, we draw closer to unraveling the mysteries of our cosmic heritage.”

Beyond science, these missions reflect the power of human curiosity and international teamwork, inspiring the next generation of explorers to push the boundaries of what we can achieve in space.

Quantum Computing: The Next Frontier and its Disruption in Cybersecurity

When the Wright brothers invented the first airplane, no one envisioned the development of pistons or turboprop engines. When those engines were eventually created, few could have imagined that this technology would one day be used in warfare, leading to devastating events like the nuclear attacks on Japan during World War II.

Similarly, quantum computing is hailed today as a groundbreaking innovation capable of solving complex problems that classical computers cannot tackle. However, the full extent of the risks associated with this revolutionary technology remains largely unknown.

In the previous article, Quantum Computing 101, we explored how quantum computers differ fundamentally from today’s classical computers. We concluded with the suspenseful question of the unknown threats they might pose.

Now, let’s delve into how quantum computing is poised to disrupt the world of cybersecurity—a domain built on the strengths of today’s technology. This transformation could redefine the foundations of digital security as we know it.

Cybersecurity: The Guardian of Digital Assets

Cybersecurity is a specialized field focused on ensuring confidentiality, integrity, and availability of data and information.

It requires organizations to proactively prepare for, respond to, and recover from potential risks that adversaries could exploit within their technology environments.

Cryptography is the backbone of cybersecurity and plays a critical role in upholding two key pillars: confidentiality and integrity. Various encryption algorithms are employed to preserve confidentiality, such as the Advanced Encryption Standard (AES) and Rivest Shamir Adleman (RSA).

Encryption is like putting your information in a secret box and locking it with a special key. Only a person with the right key can open the box and read the information. For example, when you send a message online, it gets encrypted so that even if someone intercepts it, they can’t understand it without the key. It’s a way to keep your data private and secure.

Similarly, hashing algorithms are designed to safeguard the integrity of information. Hashing is like creating a unique “digital fingerprint” for a piece of information. Imagine you have a special stamp that turns any word, number or file into a unique pattern. Even if the original thing changes a little, the fingerprint will look completely different. It’s a quick way to identify or verify something without revealing the original information.

Beyond these, cryptographic techniques also achieve other objectives, such as ensuring non-repudiation through digital signatures—but that’s a discussion for another day.

The Fundamentals of Modern Cryptography

Encryption is a powerful technique used to protect data and information, ensuring that only the rightful owner or those granted access can view it. Think of encryption as a lock for your digital assets. Symmetric encryption is like a lock with a single key referred to as a “private key.” This key can both lock and unlock the data, meaning anyone with access to the private key can use it.

On the other hand, asymmetric encryption works differently. Imagine a special mailbox with two keys: a public key to lock the mailbox and a private key to unlock it. Anyone with the public key can drop a letter (i.e., encrypt data), but only the owner with the private key can retrieve and read it (i.e., decrypt data).

Both symmetric and asymmetric encryption algorithms are widely used depending on the context and are highly effective at preserving data confidentiality.

Quantum Computing: A Leap That Changes the Rules

In the 1980s, scientist David Deutsch proposed a groundbreaking concept of a universal quantum computer, demonstrating how quantum mechanics can be used for computation. Later, quantum gates and circuits were formulated laying the groundwork for quantum computation.

In 1992, one of the first algorithms (notably Bernstein Vazirani Algorithms and Deutsch Josza Algorithm) was formulated to show the advantage of quantum computers over classical computers, until 1994, when a mathematician and computer scientist Peter Shor proposed an algorithm to efficiently factor large integers.

Asymmetric cryptography particularly like RSA relies on the difficulty of factoring as a security basis. That’s when it was known that when the time comes, asymmetric cryptography will be cracked.

In 1996, computer scientist Lov Grover formulated an algorithm to search unsorted databases more efficiently than classical algorithms. Symmetric key algorithms (e.g., AES, DES) rely on the secrecy of the key used for encryption and decryption. The security of these algorithms is typically based on the difficulty of brute-forcing (a mechanism to make continuous attempts) the key, which requires examining 2k possibilities for a key of length k.

With Grover’s algorithm, the time required to brute force a symmetric key of length k is reduced from O(2k) to O(2{k/2}). For instance:

  • A 128-bit key, which provides a classical brute force security level of 2128, would only require O(264) operations with Grover’s algorithm. This is still computationally intensive but significantly less so than the classical counterpart.
  • A 256-bit key (considered very secure today) would only require O(2128), making it vulnerable to future quantum computing capabilities.

Grovers Algorithm Cracking Symmetric Cryptography

Imagine a massive safe with a combination lock used to protect valuables. This safe uses a long, complex combination (like a symmetric encryption key) that would take someone years to guess through trial and error.

Normally, if a burglar tried every possible combination, it would take them millions of attempts to unlock the safe. But now, imagine a “magic lockpick” (Grover’s algorithm) that allows the burglar to try combinations much faster, effectively reducing the time needed to open the safe to only thousands of attempts.

With this magic lockpick, the burglar can open the safe much sooner, making the safe less secure. Similarly, Grover’s algorithm would allow a quantum computer to break symmetric encryption keys (like AES) in a fraction of the time it would take using traditional brute force methods.

Shor’s Algorithm Cracking Asymmetric Cryptography

Imagine you have a treasure chest locked with a combination padlock. The lock was designed by combining two giant secret numbers (representing the private key in asymmetric encryption). Normally, figuring out these two numbers would take even the best detective thousands of years because they’d have to try every possible combination.

But Shor’s algorithm gives our detective a magic shortcut. Instead of thousands of years, the detective can instantly figure out the two numbers, opening the lock in minutes.

In cybersecurity terms, this is how Shor’s algorithm could quickly break asymmetric encryption systems like RSA, which rely on the difficulty of finding those two large numbers.

Are We at Risk Today?

You might now be asking, “Am I compromised?” The unsettling answer is, “We don’t know yet.”

We live in an era of covert warfare, and cyberwarfare is no exception. While there is no public evidence of quantum computers with the capacity to break modern cryptographic algorithms, the possibility remains. Hackers today are harvesting encrypted data, stockpiling it in anticipation of a future where powerful quantum computers could decrypt it effortlessly.

Should you be worried? Practically speaking, not yet, unless you’re dealing with mission-critical information that could significantly impact the future.

Preparing for the Post-Quantum Era?

However, the threat isn’t being ignored. Recently, NIST (National Institute of Standards and Technology) released a finalized set of Post Quantum Cryptography (PQC) algorithms designed to resist quantum attacks. These algorithms aim to replace existing encryption standards, ensuring the digital infrastructure remains secure in the quantum era.

The NIST-selected algorithms, such as Kyber, Dilithium, and Falcon, work on entirely different principles from traditional cryptographic methods. These algorithms leverage complex mathematical structures like lattices to create encryption schemes that are resistant to quantum decryption.

Theoretically, they provide a robust defense against quantum threats, but transitioning to these new standards will take time. The sooner organizations begin this transition, the safer they will be.

What Lies Ahead?

You may wonder, “If quantum computing threatens cryptography, what about other aspects?” The answer is that the extent of the quantum threat is currently unknown.

Just as no one foresaw the first airplanes becoming warfare tools, we can only speculate about the potential misuse of quantum computers. Could a cobbler use quantum technology in ways we can’t yet think of? Perhaps. Could new and unforeseen threats emerge? Certainly.

What we do know is that the post-quantum era is near, bringing surprises and discoveries. As we prepare for the quantum future, we must remain vigilant and proactive, adapting our systems and strategies to navigate this uncharted terrain.

Weather wonders that left us puzzled in 2024

Bastian Werner, a German photographer, has recorded multiple events of ice halos around the sun since December 2023. This image features Ice Halos over Bavaria (APOD: 2023 Dec 20), a 22-degree halo, a 46-degree halo, the heliac arc, and other arcs. It was selected as NASA’s Astronomy Picture of the Day (APOD), highlighting the beauty of atmospheric optics.

Rare climatic effects arise when conditions take an extreme form. Examples include Morning Glory Clouds, ice halos, light pillars, derechos, haboobs, and similar phenomena. These effects signify the intricate dynamics of Earth’s climatic system and its sensitivity to natural and anthropogenic impacts.

This article aims to highlight rare climatic effects that are not commonly discussed but have a significant impact on the environment. It seeks to provide insights into these phenomena, which are not well known to the general public, and to raise awareness about the severity of these climatic issues.

Morning Glory Clouds

Morning Glory clouds are a rare yet captivating atmospheric event in which long, cylindrical cloud formations spread hundreds of kilometers across the sky. They appear in the early hours of the day, from September to November, in northern Australia near the Gulf of Carpentaria.

Meteorological conditions associated with their appearance include the interaction of sea breezes, atmospheric overturns, humidity levels, and strong horizontal rolling motions. Their scenic beauty fascinates pilots and gliders, and the rolling airflow creates notable lift for them. Morning Glory clouds provide a unique and dramatic spectacle, illustrating the complex interplay of weather and geography.

Morning Glory clouds have limited climatic effects as they are localized. They indirectly affect weather patterns by forming roll vortices, which influence local wind patterns. Wind shifts impact aviation. The mixing of cool, moist, warm, and dry air layers causes temperature inversions, thereby impacting local thermal conditions.

The clouds trap moisture, causing changes in humidity in the lower atmosphere for a short period. Morning Glory clouds also provide insight into the development of storms. In addition to Morning Glory clouds, Morning Glory cloud tubes, Morning Glory clouds over the oceans, and Morning Glory cloud waves pose surfing challenges to gliders.

Ice Halos

Ice halos are optical phenomena created by the interaction of sunlight or moonlight with ice crystals in the atmosphere. These beautiful exhibitions occur when light is scattered by hexagonal ice crystals in cirrus or cirrostratus clouds present in the upper levels of the troposphere (5–10 km). The appearance of ice halos depends on the orientation and shape of the crystals.

Common types of ice halos include the 22-degree halo, parhelia (sundogs), circumzenithal arc, and pillars of light. Ice halos are often observed in colder climates, but their appearance can occur anywhere depending on atmospheric conditions.

Ice halos are observed when cirrus or cirrostratus clouds contain ice crystals, indicating moisture at high levels in the atmosphere. Therefore, they indirectly suggest the likelihood of rain or snow in the coming days. The formation of halos often leads to clearer skies as they suppress storm development and prevent convection. In polar regions, ice halos are common, creating dramatic optical effects and influencing the intensity of solar light reaching the Earth’s surface.

Light Pillars

Light pillars are optical phenomena exhibited as vertical columns extending either upward or downward from a light source. They are often seen at night and are caused by the reflection of light from ice crystals, similar to ice halos. The difference is that their formation can result from both natural and artificial light sources. The light is reflected toward the observer, creating a glowing vertical column.

Light pillars

They are commonly observed in colder climates where ice crystals are abundant. They are most noticeable during winter when the air is cold enough to sustain ice crystals and clear enough to allow the passage of light. The intensity of the color of a light pillar depends on the light source and atmospheric conditions. The brightness of the color fades as it moves farther from the light source. The range of colors observed includes white, red, blue, and orange.

Light pillars indirectly contribute to our understanding of the atmosphere. Their formation requires the presence of ice crystals in the atmosphere, so observing light pillars indicates their presence. Light pillars occur during clear and cold weather, making their observation an indicator of stable atmospheric conditions.

Derechos

Derechos are extensive, lasting windstorms linked with fast bands of intense thunderstorms. The intensity of the winds can extend up to 390–640 km, often covering areas hundreds of kilometers wide. Derechos occur in the central and eastern United States, as well as in Europe, South America, and Asia.

Derechos
Derechos can produce hurricane-force winds over extremely large areas so they are sometimes referred to as “inland hurricanes”. Photo:https://www.weather.com/

They are witnessed in warm and moist environments and are aggravated by a cold front. Unstable factors in the atmosphere create a “bow echo” from thunderstorms, which is a salient feature of Derechos. Progressive derechos are more common in the summer, while serial derechos are observed in colder seasons.

Derechos cause damage in a couple of ways. They uproot trees, destroy buildings, and alter power lines. They are dangerous for outdoor activities and for people living in mobile homes.

Derecho, 2024

A derecho followed by a tornado outbreak was recorded between 1st  and 3rd April 2024, affecting the Midwestern and Southeastern United States. On 16th May 2024, a severe derecho struck the Gulf Coast, causing damage in the Houston metropolitan area. Between 15th and 16th  July 2024, a derecho moved from Iowa through Indiana, with wind speeds reaching up to 75 mph and producing several tornadoes across the Midwest.

Haboobs

Haboobs are severe sandstorms observed in arid or semi-arid regions due to strong winds from thunderstorms. The term “haboob” is derived from the Arabic word “habb,” which means “blow.” It was first used to describe these storms in the Sahara Desert and the Middle East. Their occurrence is also witnessed in desert regions of North Africa and the Arabian Peninsula. Evidence has been gathered from the southwestern United States and Arizona during the North American monsoon season.

Haboobs form due to downdrafts hitting the ground and spreading outward on all sides. The wind lifts sand particles in the form of rolling clouds, and the thunderstorm appears as a towering wall of dust, rising thousands of feet and stretching for miles. Visibility drops to zero during a haboob, posing a danger to travelers. They are commonly formed during dry months.

Some of the concerns linked to haboobs are that dust inhalation can lead to respiratory issues. They can cause visibility loss to hazardous levels, leading to accidents. Haboobs also contribute to soil erosion and the transportation of nutrients and pollutants over extended distances.

Haboob, 2024
Haboob was observed in Central California on 11th November 2024.

In 2024, several notable haboobs were recorded across different regions, including Central California on 11th November, New Mexico, and West Texas (exact dates unspecified), and Arizona on 24th April. The San Joaquin Valley in Central California was struck by a thick dust storm, creating an alarming situation across the landscapes of Fresno, Kings, Madera, and Tulare counties. The visibility dropped to zero, and the haboob was referred to as a “wall of dust,” rarely recorded, with a height of more than one thousand feet.

These rare climatic effects provide a picture of the complexity of the Earth’s atmosphere. Other such effects include Mammatus clouds, steam devils, ball lightning, fog bows, cloud bows, glories, Undular bore, Kelvin-Helmholtz clouds, sea smog, maelstroms, oceanic vortices, sea sparkle, icebergs with rainbow colors, sea foam, oceanic cloud bows, sea fogbows, mirages, ice discs, waterspouts, and moonbows, to name a few.

Understanding these climatic impacts as a whole can help monitor and prepare for what can be avoided and can better protect all communities.

Women belong in the kitchen Lab: Science, gender and Revolution in Lessons in Chemistry

Lessons in Chemistry, a show set in the mid-20th century and based on a famous novel by Bonnie Garmus [1], portrays the life of Elizabeth Zott, an excellent chemist with a hobby of cooking. It explores her journey as she is forced to navigate a world where her intellect is underestimated and her passion for science is constantly challenged by systemic biases.

Elizabeth Zott’s laboratory scenes emphasize the meticulous nature of experimental chemistry, demonstrating techniques such as titration, crystallization, and molecular analysis. From the first episode where she uses the distillation apparatus to make coffee for her colleagues to the scene where she builds a laboratory in her kitchen, the show has a smooth flow with scientific accuracy.

The scientific explanations in the show are easy to understand with the mere use of science jargon. The show was set in the 1950s and most of the scientific advancements of that era are common knowledge today.

The theme of the show is the application of chemistry in daily life. When Zott’s research was stolen, she started hosting a television cooking show and used her platform to teach scientific principles through cooking. This innovative approach serves as a way to communicate chemistry to the public and empowers women by linking scientific understanding to practical, everyday tasks.

For example, Elizabeth explained the chemical reactions involved in baking bread, the role of emulsifiers in sauces, crystallization, and the molecular changes that occur during fermentation. These explanations elevated cooking from a domestic chore to a scientific endeavor, challenging societal perceptions of women, and emphasizing that science permeates every aspect of life.

The show connects chemistry to the kitchen and illustrates the universality of scientific principles and the potential for science to be both accessible and empowering. It is a fun and accessible way of communicating science to a part of society that was discouraged from participating in science. Eventually, it encouraged women to pursue their goals as evidenced by a woman starting medical school in her late thirties after taking inspiration from Elizabeth.

The series also explores the intersection of gender and science, offering a critique of the patriarchal structures that dominated scientific institutions during the mid-20th century.

Elizabeth’s journey highlights the challenges faced by women in science, such as exclusion from research opportunities, lack of recognition for contributions, and the pervasive belief that women were inherently less capable in scientific endeavors. Unfortunately, such discrimination persists as we move up to higher positions or leadership positions in academia even in today’s time.

Her character defies these preconceptions by exhibiting resilience and intellectual prowess. Regarding the historical exclusion of women from science and the wider societal consequences of that exclusion, the play makes a significant remark. Lessons in Chemistry emphasizes the value of diversity in scientific research and the necessity of removing obstacles that impede fair participation by portraying Elizabeth as a chemist who defies gender norms.

In the mid-20th century, Lessons in Chemistry had a big cultural impact due to its scientific content mainly for women. Elizabeth Zott served as an example of how intelligence, willpower, and scientific interest transcend gender boundaries. It conveyed a strong message about persistence in scientific research with a lead female scientist who succeeded despite structural obstacles.

In the first episode she says, “Of course, I would be much further along in my research if I wasn’t making excellent coffee for mediocre scientists.” 

Additionally, the series relates to current debates concerning equity in STEM fields. By drawing attention to the historical obstacles that women in science have encountered, it highlights the continued need for assistance and inclusivity for underrepresented groups in science. The story serves as a reminder that advancing science involves more than just making discoveries; it also entails fostering an atmosphere that allows for the growth of different viewpoints.

In Lessons in Chemistry, Calvin Evans, a gifted chemist, is Elizabeth Zott’s staunchest supporter and scientific equal. Calvin regarded her as an equal and acknowledged her academic expertise, providing both personal dedication and mentorship.

Calvin’s character highlighted the significance of collaboration and equal partnership in furthering scientific advancement and dismantling social obstacles. Calvin showcased this quality and published their research with Elizabeth as the first author even though the research institute committee opposed it and didn’t let them submit for the grant.

Lessons in Chemistry beautifully combines the emotional weight of personal challenges with the discipline of scientific inquiry to provide an interesting look into science, gender inequity, and resilience. The presentation is thought-provoking and inspirational because of its dedication to illustrating the difficulties of women in science and the intricacies of chemistry.

It does have certain shortcomings— some storylines feel extraneous or unnecessary at points, and the narrative occasionally drifts into over-dramatization, which drifts from the main themes of science and determination.

From Land to Sea— The journey of Whales and Dolphins

Evolution is an incredible story of how life on Earth has grown and changed over billions of years. It’s the idea that every living thing, from the tiniest bug to the largest animal, to the oldest plants, are all connected and have adapted over time to survive. At its core, natural selection is a simple but powerful idea that says creatures best suited to their environment are more likely to survive and pass on their traits.

Over countless generations, these little changes add up and create the amazing diversity of life we see today. You can find proof of this everywhere, from fossils to the DNA we share with other species. So it is safe to say that evolution is the belief that all living organisms are connected and creatures adapt to their environment.

Cetacean on earth

Whales and dolphins belong to the order Cetacea, the marine mammals. Most amazingly, their ancestors once lived on land before they gradually adapted to living in water over millions of years. Fossils found in the present Pakistan and India of those ancient cetaceans are highly useful in understanding their fascinating evolution and the transition from land to sea.

This journey explains the flexibility of cetaceans and the remarkable forms they took to thrive in aquatic habitats, such as streamlined bodies, modified limbs for swimming, and an enhanced respiratory system. All these changes helped them to adapt to oceanic spaces to travel and become a part of an intricate social structure. By observing this we can safely say that nature remains at its best through dramatic changes over long time scales.

Relatives of cetaceans

Today’s cetaceans’ closest living relatives are Artiodactyls which include hippos and cows. Their last common ancestor lived around 55 million to 60 million after that cetaceans became semi-aquatic and artiodactyls stayed on land. Cetaceans took to the sea to look for food and protection.

Pakicetus— the first cetacean

Pakicetus was the first cetacean to start being semi-aquatic around 50 million years ago. Pakicetus was a wolf-like animal, its fossil shows that it was semi-aquatic and it could run on land. At this stage, its diet consisted of fish and small rodents.

Ambulocetus— the walking whale

About 49 million years ago a cetacean known as Ambulocetus roamed; it was dubbed the “walking whale” because it showed much more aquatic characteristics compared to its previous ancestors. Though it was still land dwelling it showed many characteristics that led it to become fully aquatic, it was about as large as a modern-day lion. It had large paddle-like limbs and a robust body which allowed it to roam on land and swim in water. It also had a vertical tail for propelling itself forward in water. It was a carnivore, its hunting style was similar to a modern-day crocodile, it used to wait in the water and ambush its prey.

Rodhocetus— the biggest transition

About 47 million years ago Rodhocetus became the latest cetacean, it showed a transition towards spending most of its time in water. Its tail evolved vertical fins. It now mainly relied on its tail to swim. A major shift was its nostrils. Its ancestor’s nostrils used to be closer to their snout but now Rodhocetus’s nostrils were closer to the top of the head which would evolve into a blowhole. Its hind limbs were smaller which became a trend in cetacean evolution.

Droudon— the first fully aquatic whale

6 to 7 million years later (40 to 41 million years ago), a cetacean known as Droudon swam in Earth’s oceans. It was one of the first cetaceans fully adapted for marine life. It had the appearance of a small whale. Its hind limbs evolved into flippers, essential for a streamlined body and swimming.

The nostrils had shifted to the top of the head and formed a blowhole to surface for air easily without tilting its head just like modern whales. Some skull features hint at early adaptations for enhanced hearing, which would later develop echolocation – the location of objects by reflected sound, in some cetacean lineages (like dolphins, orcas, and some whales).

Basilosaurus— made for the open ocean

About thirty-five million years ago, an 18-meter cetacean known as Basilosaurus swam. It had an eel-like body so unlike the dorudon the basilosaurus swam in a serpent-like motion. Their diet consisted of fish and other smaller marine mammals. It was the first cetacean whose body was made for the open ocean. They adapted earbones that could sense the water currents. This ability was crucial for sensing prey.

Tooth whales and baleen whales 

Finally, some 34 million years ago, basilosaurus split into toothed whales and baleen whales. Toothed whales include dolphins, orcas, and sperm whales. Toothed whales are all carnivores and they mainly hunt in deep dark oceans which is why they all use echolocation. It works when an animal emits clicks or sounds and waits till the sound bounces back to ”see” what is in front of it. Most toothed whales display high levels of intelligence, particularly dolphins who live in pods and coordinate hunting attacks. Toothed whales have been documented to be much smaller than their cousins baleen whales.

Baleen whales are a group which includes almost all types of whales. Baleen whales are filter feeders which is why they have baleen plates to filter large amounts of krill, hence the name. Most baleen whales migrate to maximize food throughout the year. Baleen whales have been documented to be quite large, reaching around a hundred feet and weighing around 190 tons.

River Dolphins

Modern-day cetaceans are still adapting to their environment. Such as both baleen and toothed whales have adapted blubber to keep themselves warm in arctic environments. Cetaceans can also store their oxygen using myoglobin which allows them to dive deep in oceans and it is crucial for sperm whales as they dive to a depth of around 3000 feet. Most whales can slow their heart rate and direct blood to crucial areas only, such as the brain and other crucial organs. This is to conserve oxygen quality which helps baleen whales dive deep.

River dolphins or freshwater dolphins have adopted some very unique features due to their environment, these dolphins have smaller eyes than normal saltwater dolphins, because rivers are quite murky and it is hard to see so this is why river dolphins mostly rely on echolocation. River dolphin’s neck muscles are much more flexible than their ocean counterpart because rivers can be quite narrow at some points so they have flexible neck muscles to maneuver around those narrow points.

The ongoing war in Gaza was a heavily covered topic this year. In a conversation with neuroscience researcher Dr Ali Jawaid, our editor highlighted the transgenerational trauma and its impacts on children. Dr Jawaid referenced scientific studies, explaining how the effects extend beyond mental health.

The attack in Gaza and severe violence of human rights has brought an unprecedented level of trauma to the children in Gaza. There is no safe place and no sense of security, with thousands displaced from their homes. Caregivers are themselves fighting for survival and are unable to help children cope with their overwhelming emotional reactions.

Firewall Misadventure— How Pakistan’s Internet Controls Hurt Innovation and Growth

Category: Technology

The internet is essential for global commerce, innovation, and communication, but internet firewalls and Deep Packet Inspection (DPI) in Pakistan are increasingly used to address cybersecurity threats and content control. While these tools enhance security and content regulation, they also introduce challenges such as slower internet speeds, increased operational costs, and reduced productivity.

According to the Pakistan Software Houses Association (P@SHA), this firewall implementation costs an estimated 30 billion PKR and has resulted in potential losses of up to $300 million. Beyond these immediate financial losses, the decision has damaged Pakistan’s reputation, as a potential tech hub, among international clients, investors, and even its tech innovators.

Microbial life & the Space industry— Do we have all bases covered?

Category: Biology

The discovery of 13 antibiotic-resistant strains of Acinetobacter bugandensis aboard the International Space Station (ISS) sparked an internet frenzy, echoing sci-fi tropes of alien microbes hitchhiking to Earth. While these bacteria are highly resilient to antibiotics due to genetic adaptations to harsh space conditions, routine microbiological assessments on the ISS confirmed they pose no immediate threat to astronauts or humanity. However, the findings highlight the broader global concern of antibiotic-resistant superbugs, driven by the misuse and overuse of antibiotics on Earth.

Doctors come across a plethora of infections caused by bacteria in their clinical practice. While those infections are treated effectively in many instances by appropriate practice, sometimes antibiotics are unduly prescribed, underdosed, or given for durations that are shorter than what would be appropriate for the infection.

Cooling Karachi – Combating Urban Heat with Green Spaces?

Category: Environment

The impact of climate change is undeniable, and areas like Karachi are becoming extremely vulnerable to it. The lack of trees and green spaces made this year’s summer unbearable and heavily affected the quality of life. Researchers argue that there is a dire need to develop parks and increase plantation efforts so the city has a sustainable cooling atmosphere and a more habitable environment.

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).

A Pioneer with Cracked Space Exploration Policy— Is the Hope Still Alive for Pakistan?

Category: Space

Pakistan’s inaugural lunar mission on May 3, 2024, marked a significant milestone for the country’s space program, reigniting national enthusiasm. Despite being a regional pioneer in space technology in the 1960s with SUPARCO’s establishment and achievements like Badr-I and PRSS-1, Pakistan’s space progress has lagged behind neighboring countries due to economic challenges, limited funding, and gaps in STEM education.

The lack of education and economic challenges are some of the basic hindrances in Paksitan’s space exploration program. Despite the challenges, Pakistan has become the sixth country to launch its first-ever moon satellite: iCube Qamar.

Gaia BH3: The Colossal Black Hole Next Door

Gaia BH3: The Colossal Black Hole Next Door

Black holes are the monstrous cosmic giants present in the vastness of space, devouring everything in their path. If one were ever close enough, the idea that they could one day pull our entire planet into their abyss might have kept you up at night as a child.

Let me bring back a little of that fear. Scientists have just discovered the most massive stellar black hole ever found, and it is not as far away as you would hope—only 2,000 light-years from Earth. That is like having a giant, hungry neighbor down the street in cosmic terms.

What are Black Holes?  

John Wheeler popularized the term black hole in 1967, describing a theoretical concept derived from Einstein’s General Theory of Relativity. Black holes were considered purely speculative until the 1960s when Robert J. Oppenheimer and others suggested they could be real physical entities rather than just mathematical abstractions.

Black holes are cosmic objects with extremely strong gravitational forces that light cannot escape their pull. They remain mysterious phenomena to this day. There are several varieties of black holes, including supermassive black holes, whose origins are still a mystery.

Sagittarius A* is a supermassive black hole located at the center of the Milky Way, theorized to have formed through the merging of multiple black holes or the remnants of successive supernovae. It was not formed directly from a stellar core collapse like Gaia BH3, a stellar black hole.

GAIA BH3

Gaia BH3 is the biggest stellar black hole recently discovered. European Southern Observatory confirmed this discovery on April 16, 2024. Its mass is equivalent to 33 solar masses. It is located in Aquila, the Eagle constellation. Astronomer Pasquale Panuzzo commented:” No one was expecting to find a high-mass black hole lurking nearby, undetected so far. This is the discovery you make once in your research life.”(Meet Gaia BH3, 2024).

Gaia BH3 is part of a binary star system with a low-metallicity star orbiting it. How can the star orbit the black hole without being engulfed by it? The answer lies in their distance; the star is too far away to be pulled into its event horizon allowing it to orbit safely. Such black holes are called dormant black holes, they do not radiate and lack accretion disks, so they remain hidden (Sleeping Giant Surprises Gaia Scientists, n.d.).

Wobbling star reveals its existence

Black holes cannot be observed directly but can be detected through their footprints or the signatures they leave behind. The term “black” reflects their nature—they do not emit any light.

Similarly, Gaia BH3 caused its companion star’s orbit to wobble, a motion detected by the Gaia spacecraft. The analysis of that data hinted at the presence of a cosmic object with gravity extreme enough to influence the star’s motion.

ESA confirmed it as the Milky Way’s biggest stellar black hole and the second closest to Earth. Carole Mundell, ESA Director of Science, commented on Gaia’s capabilities, “It is impressive to see the transformational impact Gaia is having on astronomy and astrophysics. Its discoveries have reached far beyond the original mission of creating an incredibly, precise map of over a billion stars in the Milky Way.”

DISCOVERY: The Gaia mission

The European Space Observatory launched the Gaia mission in 2013, to make a three-dimensional map of the universe. Another purpose was to collect data about the positions and radial velocities of stars and other cosmic objects to study their properties precisely. It can chart up to 1000 million stars accurately, enabling astronomers to conduct statistical analysis. This is indeed just 1 percent stars of the Milky Way (Prusti et al., 2016).

Gaia spacecraft is currently present at Lagrange-2 point and uses the principles of astrometry to observe the changes and velocities of cosmic objects; it is 200 times more accurate and produces data for more stars as compared to its predecessor Hipparcos(Gaia Overview, n.d.). Hipparcos was only able to chart the positions of 100,000 stars.

Jos de Bruijne, Gaia’s deputy project scientist at ESA, described the challenge as being “the same as if you are trying to tell the shape of a building while you are inside it.” He emphasized that understanding the galaxy’s shape requires knowing the exact positions of its stars, which are both very far apart and very distant from us. “To accurately measure their positions in three dimensions requires extreme precision,“ he added(published, 2022).

Gaia BH3 has shocked astronomers with its strangeness and the fact that it remained hidden for so long. However, the Gaia mission has changed all that—now it is all about knowing where to point your telescopes, as a famous quote in the world of astronomy goes. This mission still holds much promise, and future data releases are expected to bring more discoveries and secrets to uncover, such as the search for exoplanets.

The upcoming Gaia Data Release 4, New Star and Solar System Planetary Catalog anticipates uncovering numerous binary systems with dormant black hole companions. Each discovery will provide a chance to test different theories about how Gaia BH3 was formed. Astronomers are now focusing on preparing for the release of DR4 at the end of 2025.

Gaia’s discoveries continue to push the boundaries of what we know about the universe, and with every new release, our understanding of the cosmos grows even deeper.

Don’t you start panicking about Gaia BH3 pulling Earth into a cosmic abyss? That childhood fear of black holes gobbling up our planet? Yeah, this is not happening. It is still 2,000 light-years away, and Gaia BH3 isn’t exactly speeding our way. So, feel free to relax, take a breath, and enjoy your day— there’s no need to start preparing for an interstellar apocalypse yet!

Sands of Time— Denis Villeneuve’s Dune, Part One Redefines Epic Sci-Fi

Frank Herbert’s nuanced classic and futuristic epic “Dune” has been adapted into a science fiction magnum opus by Canadian filmmaker Denis Villeneuve. Being a more critically acclaimed version, the film profoundly portrays Herbert’s omniscient world-building in an astounding cinematic spectacle.

The novel, being a million-dollar best-seller, is considered “one of the greatest science fiction novels of all time.” Adapting it onto the big screen is no less than a miracle, as Villeneuve manages to cover the 800-page complex life of Paul Atreides in Arrakis over two hours and thirty-five minutes of run-time.

Dune Part one

The film takes place in a futuristic setting in the year 10191. The story follows Paul Atreides played by Timothy Chalamet who is sent to the planet Arrakis with his parents, Lady Jessica and Duke Leto Atreides, played by Rebecca Ferguson and Oscar Isaac, to take over after the former rulers, the ruthless Harkonnens. Arrakis, informally known as Dune, is a fictional planet featured in Herbert’s novel and is integral to the film’s central plot for several reasons.

Despite being inhabitable and protected by massive sandworms, it serves as grounds for harvesting “spice” as whoever has control over Arrakis has control over spice. Additionally, it is a passage to interstellar travel, of which only the savage Fremen hold knowledge. As Paul’s fate as future ruler hangs in the balance, he navigates the impenetrable landscape of Arrakis with the help of the Fremen, letting the Dune saga unfold.

The casting is impeccable as Timothy Chalamet brilliantly embodies the role of Paul, a teenage boy, who is unaware of how to utilize his position after his father, Duke Leto. Lady Jessica played by Ferguson effortlessly personifies Paul’s dominant mother and her exposition of Bene Gesserit in the novel is equally impressive and a personal favorite.

The film also does a commendable job of incorporating intricate themes to complement the film’s central plot for example Paul’s prophecy as Muád’Dib, the discreet operations of Fremen, and the sinister plotting of the Harkonnens. The viewers are kept in the loop of various events occurring one after the other in the Dune universe which hint at something larger in the future. However, some events in the film may give a superficial impression to the viewers who have not read the novel in the first place.

Nonetheless, Villenuave compensates for this lack of context by showing Paul’s visions or dreams in which he meets Chani, another character, played by the enigmatic Zendaya. This meeting foreshadows Chani’s significance in Paul’s future journey amongst the Fremen.

Unlike the intended illusionary vision Herbert had for his novel, Villeneuve’s direction for Dune differs, as Villeneuve directs the movie in more of his signature style as seen in his prior films namely Blade Runner 2049 and Arrival. David Lynch, on the contrary, directed Dune in the year 1984, per the novel’s psychedelic ambiance.

With a distinct futuristic cinematography style, Villeneuve carefully orchestrates wide-shot images of sandstorms, spaceships, and Paul’s visions through the equivocal and extraordinarily gifted cinematographer, Greig Fraser. Both Fraser and Villeneuve make use of long monologues in the novel to visualize Arrakis mostly from Paul’s point of view throughout the film.

My favorite aspect is the utilization of a visceral monochromatic color palette which goes hand in hand with Greig’s shooting style. For this purpose, Greig particularly insisted on the use of shooting the scenes in natural light with sand screens to create proper reflection. In addition to this, both Fraser and Villeneuve experimented with adjusting camera angles for shooting technical scenes such as the scene with the ornithopter spinning around the worm.

The soul of Herbert’s book lies in establishing a link between the ecosystem and spirituality and the director-cinematographer duo masterfully engineer this phenomenon through specific shots in the film. Greig’s ability to fully immerse himself in various cultures and capture relevant moments coupled with Villeneuve’s scientific documentation takes a coming-of-age approach to this book-film adaptation and is indeed genius, if you ask me.

Secondly, if we were to talk about the costume design, the outfits for every character in the film are meticulously selected according to their character arcs. They are crisp, antique, and seem like they weigh a ton, at least!

If you think production design and cinematography are the icing on the cake, wait till you are mesmerized by the stunning editing and soulful music score. German film composer, Hans Zimmer, reunited with Villeuneve for Dune after Blade Runner 2049 for this project. Despite Zimmer’s former supposed commitment to Cristopher Nolan’s Tenet, he picked Dune instead owing to his childhood love for Herbert’s novel. Paired with BAFTA winner Joe Walker’s intuitive and timely editing, the film creates its rhythmic beats, certainly serving the cherry on top!

This book-film adaptation stands out because of Herbert’s take on the Bedouin culture, which is intricately woven into the characters’ lives in the Dune universe. As a Muslim viewer, reading the novel and watching the film in the theater kindles many emotions as you relate to the Islamic themes of dynasty politics, pilgrimage, and prophecies. It is both surreal and nostalgic. Consequently, to include an Islamic narrative in a pro-westernized film fraternity only to take it up as a massive budget project had me sold for the first day, first show!

Dune is a relatively slow-paced film and can be watched without reading the novel. The film’s marketing, however, was overblown but that might have been necessary to compensate for the large-scale investment in giving life to Herbert’s Dune universe. As most scenes are infused with imagery and colossal visuals, the prospects of experiencing individual character arcs, except for Paul, relatively become less.

Though, for sci-fi zealots like myself and those who have long treasured Herbert’s Dune, Villeneueve has certainly done justice to the book-film adaptation we all dreamt of. All in all, Dune is a bang for the buck! It’s both an auricular and visual feast with an ensemble cast, leaving viewers craving for more—be sure to watch part two where the dunes of Arrakis promise even stronger battles and revelations!

The facts about Al Beruni’s experiments at Nandana, Pakistan

Nandana is situated in District Jhelum, Pakistan, about 60 miles southeast of Islamabad in a straight line and can be reached by road in less than 3 hrs. In the long past, Nandana was a Capital city of historic importance and also was an administrative district until the second half of the ı8th century A.D. It had remained more or less inhabited up to the 18th century but was abandoned thereafter and the population shifted to Baghan wala down below in the plain.

Presently the site is abandoned and has recently been protected by the Department of Archaeology.  To this day, as one visits it, one cannot miss the conspicuous sight of the high mount or its peak point to which Beruni had once claim bed up to take measurements for his experiment. These stand out clearly in the light of Beruni’s own observations.

For a long time, Beruni was anxious to access the sources of Hindu literature, astronomy, and other sciences. During the period of his service (399-406 A.H) with  Abul Abbas Mamoon Khwarizmshah, he became better acquainted with the power and position of Sultan Mahmud and the importance of the Ghazna court as a gateway to India.

During his stay at Nandana, Beruni had accomplished more than one task. By halting at Nandana and making it a center for his inquiries, Beruni extended his visits into the surrounding region, which was also rich in minerals, and Beruni was equally interested in precious stones.

In Nandana, Beruni observed the latitude of the place, which he noted in his Kitâb al-Hind, and the latitudes of other places he had personally visited. The figure for Nandana (as given in the printed edition) is 32′-o. 60 Later, Beruni also calculated the longitude of Nandana (from the westernmost Coastal point of Maghrib, North Africa), revised the figures for its latitude, and recorded both figures in his al-Qanun-al-Masudi. In the printed edition of this work, the longitude and the latitude of ‘Fort Nandana’ are 94° — 43′ (E) and 330— 10′ (N), respectively.

Nandana: The Scene and setting for the experiment

Beruni’s approach to Nandana was natural from the northwest along the age-old route, traversing the roof-like elevated Ara valley and then descending south-eastward (from the sector of the present Ara village and the Ara Rest House) towards the Nandana Pass. The environment enrooted to Nandana, as it would have appeared and impressed Beruni, can best be visualized through the vivid description of it left by a modern researcher (Sir Aurel Stein) following the footsteps of Beruni: “I may now proceed to give an account of the route leading down from the Salt Range through the Pass of Nandana, and the remains of the ancient stronghold.

From the elevated ground of the Ara Plateau, at the height of about 2,400 feet, a steep winding road leads down over the rocky scarp of the range for close to 2 miles to where a small dip, about 200 yards across, at an average level of 1,300 feet stretches between two small valleys drained by streamlets which further south unite below the ruined stronghold of Nandana.  

Immediately above the dip referred to, which forms a natural fosse, raises the bold rocky ridge of Nandana very abruptly. On its top, at the height of about 1,500 feet above sea level, it bears conspicuous ruined structures, and along the precipitous northern slopes below these, the remains of a boldly built one of the walls, defended by bastions.

This fortified ridge completely bars further descent on the route; for the two small valleys above-mentioned contract on either side of it into deep and extremely narrow gorges, and descend for some distance between almost vertical rock walls, hundreds of feet high.” 62 As one approaches the site, the rocky ridge’s northern slope on which stood the fortified inner city becomes prominent.

Before negotiating its bottom line, one passes through the ruins of the outer quarters of the city. Proceeding further and following the track higher up on the slope, the massive foundations of the fortification wall skirting around this northern side and the remnants of the gateway leading into the walled city.

Though Beruni had a partial view of the plain through the Nandana Pass from his own quarters, he could not fully view it unless he either went on the other side of the Pass or climbed up the mountain. He preferred to go up to the mountain top to size up the plain and the peak point where vertical measurement to its foot could be taken.

To do so, he must have come out of the fortified part of the city, passed through the lower part of the city, traversed a long way toward the north-west, crossed the shallow rivulet waters flowing downwards into the gorge, climbed up the slopes of the spur along its north-western shoulder and reached high up on the top before he could have a full view of the plain. When he did so and had a full view of the vast level plain extending southward far off to the horizon, he took the final decision to try out his new method for determining the dimensions of Earth.

The problem and the method for its Solution

Al Beruni concluded that the method of finding, by trigonometrical calculation, the circumference or other dimensions of Earth by observing the dip of the horizon from the peak of a mountain was a fresh contribution by Beruni. He applied this method for the first time in his Nandana Experiment during 4 11-4 14 A.H.

He ascertained the sight line (extending) from the mountain peak (and) touching where the earth and the blue sky met (the horizon). The line so visualized from (my) standing position (on the peak) dipped against the (horizontally) fixed line by (an angle of) o° 34′. T h en I measured the (peak to bottom) perpendicular height of the mountain and found it to be 652-3-58751 zirac (cubits), reckoned by the z^âc used as a cloth measure at that place (Nandana). Now angle T is a right angle, angle K equal to (the angle of) the dip (° 34′), and angle H as its complementary = 89° 26′.

So if the angles of the triangle H T K are known, its sides will also be known by the proportion of T K and sines lotus ( = 1). By this proportion, T K will be 590 59′ 49″ while the excess between it and sinus lotus is o° o 11″. But that is the perpendicular height HL which is known in zirac, and the ratio of its (HL) zirac to the zirac of L K is the same as the ratio of o° o’ 11″ to 590 55″.

Rapid Innovation in Quantum Computing is Reshaping the Landscape of Digital Security

Recent advancements, such as China’s Tianyan-504 system and Google’s Willow chip, demonstrate substantial progress in designing qubits—quantum units of information that exploit superposition and entanglement to process data at scales unimaginable with classical bits. Although these devices remain technically challenging and limited in scope, the rate of improvement suggests a future in which quantum hardware may break through longstanding cryptographic defenses.

This shift threatens conventional encryption methods used in financial transactions, government communications, and personal data protection and reverberates through Web3 ecosystems. Decentralized platforms, blockchain-based financial instruments, and tokenized digital assets rely heavily on cryptographic primitives that could become vulnerable to quantum attacks. Organizations and communities worldwide now face a pivotal choice: adapt to this new reality by adopting quantum-resistant solutions or risk exposing their digital infrastructures to unprecedented threats in the years ahead.

Quantum Hardware and Algorithms: Redefining Security Threats

At the heart of quantum computing’s promise lies the qubit, a fundamental building block that can exist in multiple states simultaneously. Engineers struggle to keep qubits coherent for extended periods, maintaining them at cryogenic temperatures and shielding them from the slightest interference.

Error-correction techniques must delicately monitor these states without collapsing them into classical outcomes. The Willow chip’s refined error management and Tianyan-504’s large qubit count point toward more stable systems. However, scaling from a few hundred to thousands or millions of reliable qubits remains a colossal challenge.

Despite these hurdles, the theoretical capabilities of quantum algorithms pose grave implications. Shor’s algorithm, for example, drastically reduces the difficulty of factoring large integers—a cornerstone of RSA-based encryption. Breaking RSA in a reasonable timeframe would upend traditional public-key systems that currently protect sensitive information.

Similarly, Grover’s algorithm accelerates brute-force searches, potentially weakening symmetric encryption methods by reducing the time required to guess keys. Although present-day quantum machines cannot yet implement these algorithms at the scale needed to shatter modern encryption, the trajectory is clear: once error-corrected, high-qubit systems emerge, cryptographic assumptions once seen as unbreakable may fail.

This looming threat extends beyond conventional cybersecurity models. Adversaries might already capture encrypted data, but they plan to decrypt it years later when quantum hardware matures. Long-lived secrets—state documents, corporate intellectual property, or sensitive health records—become vulnerable to a “harvest now, decrypt later” strategy. The prospect of future quantum decryption elevates the urgency of preparing defenses today, rather than waiting for quantum supremacy to catch organizations off guard.

Quantum Vulnerabilities in Web3 Ecosystems

The Web3 movement envisions a decentralized internet powered by blockchain technology, decentralized finance (DeFi) protocols, non-fungible tokens (NFTs), and smart contracts executing across distributed networks.

These platforms depend on cryptographic mechanisms to maintain trustless environments, secure digital identities, and manage tokenized assets without centralized intermediaries. Private keys underpin the ownership and transfer of cryptocurrencies and tokens, while secure hashing functions and digital signatures preserve network integrity and ensure participants adhere to protocol rules.

Quantum computing threatens to undermine these foundations. If malicious actors harness quantum algorithms to derive private keys from public addresses or forge digital signatures, they could manipulate smart contracts, drain liquidity pools in DeFi applications, counterfeit NFTs, or sabotage blockchain consensus. The ramifications would be devastating for users who trust the immutability and cryptographic reliability of these systems.

The decentralized nature of Web3 complicates the defense. Network-wide algorithmic upgrades require consensus among diverse participants—miners, validators, developers, and token holders—making transitions to quantum-safe cryptography a complex social and technical endeavor. Failing to address quantum risks may erode confidence in decentralized ecosystems, leading to market instability, devalued assets, and lost user trust.

Quantum-Resistant Cryptography and Defensive Strategies

Anticipating these challenges, researchers and standards bodies have focused on post-quantum or quantum-resistant cryptography. Unlike current methods that rely on problems easily solved by Shor’s or Grover’s algorithms, quantum-resistant schemes emerge from different mathematical foundations. Lattice-based cryptography, for instance, exploits the complexity of finding short vectors in high-dimensional grids. Code-based systems use error-correcting codes to present problems resistant to known quantum approaches. Multivariate cryptography and hash-based signatures add further variety, each grounded in assumptions that remain robust against quantum assaults.

International efforts, including those led by the U.S. National Institute of Standards and Technology (NIST), aim to standardize these new algorithms. The selection process involves rigorous security analysis, efficiency testing, and implementation checks. Once a stable of proven quantum-resistant algorithms is established, migrating classical and decentralized systems to these standards will become a priority. Financial institutions, government agencies, and Web3 developers can then adopt these algorithms to safeguard future transactions and communications.

On top of cryptographic shifts, other quantum security tools offer additional resilience. Quantum key distribution (QKD) uses quantum states to exchange keys securely, revealing any eavesdropping attempt. Though challenging to implement at large scales and not a panacea, QKD could complement quantum-safe encryption methods, establishing a multilayered defense for critical connections. Meanwhile, quantum-secure protocols might enhance authentication systems, detect anomalies more efficiently, or ensure data integrity, turning quantum principles into defensive assets rather than threats.

In the Web3 arena, upgrading smart contracts to incorporate quantum-resistant keys and adjusting hashing algorithms become vital tasks. Developers may deploy hybrid approaches, mixing classical and post-quantum cryptography to ensure backward compatibility while incrementally strengthening security. Such gradual transitions help prevent sudden shocks and maintain user confidence.

Navigating the Post-Quantum Transition and Future Outlook

The current limitations of quantum hardware give defenders a valuable head start. The quantum machines of today, including Tianyan-504 and Willow, remain at a proof-of-concept stage, still grappling with error rates and coherence issues. Yet, ignoring this window of opportunity would be shortsighted. Organizations must inventory cryptographic assets, identify vulnerable algorithms, and plan orderly migrations to quantum-resistant solutions. The cost of inaction grows with each step quantum computing takes toward feasibility.

For Web3 communities, consensus-based upgrades may require on-chain governance votes or carefully orchestrated forks. Protocols might establish timelines for phasing in quantum-safe schemes, ensuring that wallets, node software, and decentralized applications support new cryptographic primitives. This collaborative adaptation maintains the core principles of decentralization—open participation, transparency, and stakeholder input—while strengthening security foundations.

Ultimately, quantum computing’s influence on cybersecurity and Web3 can be managed through foresight and preparation. Rather than reacting to a crisis once a powerful quantum machine is unveiled, the global community can adopt preventive measures now. Incorporating quantum-safe cryptography, experimenting with quantum-secure protocols, and preparing migration paths for decentralized networks position organizations and users to weather the quantum transition.

This proactive stance preserves the integrity and functionality of financial services, digital marketplaces, and governance mechanisms that define the decentralized internet. It reassures participants that their assets and identities remain protected even as computational frontiers expand. Quantum computing may reshape cryptographic challenges, but with careful planning and timely implementation of new standards, the promise of a secure digital ecosystem—classical or quantum—can endure.
