In News:
Wave Life Sciences became the first biotechnology company to treat a genetic condition by editing RNA at the clinical level.
- What is RNA Editing?
- Definition: RNA editing is the modification of messenger RNA (mRNA) after it’s synthesized from DNA but before it is translated into proteins.
- Process: mRNA consists of exons (coding regions) and introns (non-coding regions). Exons code for proteins, while introns are removed before protein synthesis.
- Types of RNA Modifications:
- Addition: Insertion of a nucleotide.
- Deletion: Removal of a nucleotide.
- Substitution: Replacement of one nucleotide with another.
- Mechanism of RNA Editing:
- Involves Adenosine Deaminase Acting on RNA (ADAR) enzymes.
- ADAR enzymes modify adenosine to inosine, which is recognized as guanosine, allowing mRNA to be corrected.
- Guide RNA (gRNA) directs ADAR enzymes to the specific mRNA region for editing.
- Clinical Use of RNA Editing:
- Wave Life Sciences used RNA editing to treat α-1 antitrypsin deficiency (AATD), a genetic disorder.
- Other potential applications include treating diseases such as Huntington’s disease, Duchenne muscular dystrophy, Parkinson’s disease, obesity, and neurological disorders.
- Challenges in RNA Editing:
- Temporary Effects: RNA editing provides temporary changes, requiring repeated treatments for sustained effects.
- Delivery Issues: Current delivery methods, like lipid nanoparticles and adeno-associated virus vectors, have limitations in carrying large molecules.
- Specificity: ADARs may cause unintended changes in non-target regions of mRNA, leading to potential side effects.
- Comparison: RNA Editing vs. DNA Editing:
- Safety: RNA editing causes temporary changes and presents fewer risks than DNA editing, which makes permanent alterations to the genome.
- Immune Response: RNA editing uses enzymes naturally found in the body (ADAR), which reduces the risk of immune reactions, unlike DNA editing tools like CRISPR-Cas9 that can trigger immune responses.
- Significance of RNA:
- Structure: RNA is a nucleic acid, similar to DNA but typically single-stranded. It consists of a backbone of ribose sugars and phosphate groups, with bases adenine (A), uracil (U), cytosine (C), and guanine (G).
- Types of RNA:
- Messenger RNA (mRNA): Carries genetic information from DNA to ribosomes for protein synthesis.
- Ribosomal RNA (rRNA): Forms the core of the ribosome and catalyzes protein synthesis.
- Transfer RNA (tRNA): Transfers amino acids to ribosomes during protein synthesis.
- Regulatory RNAs: Regulate gene expression.
- α-1 Antitrypsin Deficiency (AATD):
- A genetic disorder where the protein α-1 antitrypsin accumulates in the liver, damaging both the liver and lungs.
- Treatments include weekly intravenous therapy or, in severe cases, liver transplants.
- RNA editing offers a potential new treatment approach.
- Global Impact:
- RNA editing is still in its early stages but shows promise for treating a wide range of genetic and chronic conditions.

Spraying Diamond Dust to cool the Earth
- 06 Nov 2024
In News:
- A new study in Geophysical Research Letters suggests that diamond dust could be more effective than any other material in reflecting solar radiation.
- Objective: The goal is to reduce global temperatures by 1.6°C by spraying approximately 5 million tonnes of diamonds annually into the atmosphere.
Background of Geoengineering Solutions:
- Geoengineering refers to large-scale interventions aimed at altering Earth's natural climate system to counteract global warming.
- One proposed solution involves spraying diamond dust in the Earth's upper atmosphere to cool the planet.
- This approach is part of Solar Radiation Management (SRM), which seeks to reflect sunlight away from Earth, thereby reducing global temperatures.
- Previous Materials Considered: Sulphur, calcium, aluminium, silicon, and other compounds have been studied to perform a similar function.
Context of Geoengineering and Climate Crisis:
- Inadequate Progress: Current efforts to mitigate global warming, such as reducing greenhouse gas emissions, have been insufficient. Global temperatures have continued to rise, and targets like the Paris Agreement's 1.5°C are increasingly out of reach.
- Rising Global Temperatures:
- 2023: Global temperatures were approximately 1.45°C higher than pre-industrial levels.
- Projected Challenge: To meet the Paris goal, global emissions must be reduced by at least 43% by 2030. However, current actions will likely result in only a 2% reduction by 2030.
Geoengineering Technologies:
- Geoengineering Methods:
- Solar Radiation Management (SRM): Reflects sunlight to cool Earth.
- Carbon Dioxide Removal (CDR): Involves capturing and storing CO?.
- SRM Techniques:
- SRM draws inspiration from natural events like volcanic eruptions, where large amounts of sulphur dioxide form particles that reflect sunlight.
- Mount Pinatubo (1991): One of the largest eruptions, which temporarily reduced global temperatures by 0.5°C due to the sulphur dioxide released.
Diamond Dust vs Other Materials:
- Study Comparison: Diamonds were found to be the most effective material compared to other compounds (sulphur, calcium, etc.) for reflecting solar radiation.
- Quantity Needed: To achieve a cooling of 1.6°C, 5 million tonnes of diamonds would need to be dispersed into the upper atmosphere each year.
Broader Geoengineering Context:
- Carbon Capture and Storage (CCS):
- CCS is already in practice, where CO? emissions from industries are captured and stored underground to reduce atmospheric carbon.
- However, CCS faces high costs and scalability issues, and safe storage sites for CO? are limited.
- Direct Air Capture (DAC): A more advanced method where CO? is directly removed from ambient air, but it faces even greater challenges in terms of infrastructure and cost.

Centre for Science and Environment
- 03 Nov 2024
In News:
Centre for Science and Environment release a report on Extended Producer Responsibility (EPR) for Plastic Packaging
Key Findings:
- EPR Guidelines (2022) were a step towards enforcing the "polluter pays" principle, but the system faces significant issues in its implementation and registration processes.
- Centre for Science and Environment (CSE) report, released on October 29, 2024, highlights gaps in the EPR system for plastic packaging and suggests corrective actions.
EPR Guidelines Overview:
- Issued by: Union Ministry of Environment, Forest and Climate Change (MoEFCC).
- Objective: Hold producers, importers, brand owners (PIBOs), and plastic waste processors (PWPs) responsible for managing plastic packaging waste.
- Key Requirements:
- PIBOs must register on a centralized portal and set targets for collection, recycling, and reuse of plastic packaging.
- Registration involves compliance with targets on end-of-life recycling and recycled content usage.
Problems Identified in the Current EPR System:
- Low Registration and Enrollment:
- 41,577 registrations on the EPR portal, but a significant discrepancy in the type of stakeholders registered.
- 83% of registered entities are importers, 11% are producers, and only 6% are brand owners.
- Producers contribute 65% of the plastic packaging in the market but have low registration.
- Absence of Key Polluters:
- Manufacturers of virgin plastics are notably absent from the portal, despite being required to register.
- Fraudulent Practices:
- 700,000 fake certificates were generated by plastic recyclers, far exceeding the actual certificate generation capacity.
- The Central Pollution Control Board (CPCB) found that such fraudulent activities are undermining the integrity of the system.
- For example, end-of-life co-processing units (e.g., cement plants) claimed to have processed 335.4 million tonnes per annum of plastic waste, while their actual capacity is just 11.4 million tonnes per annum.
- Underreporting and Mismanagement:
- Despite 23.9 million tonnes of plastic packaging being introduced into the market, the CPCB’s estimation of plastic waste generation (4.1 MT annually) is underestimated.
- Lack of Stakeholder Representation:
- Urban local bodies and informal waste collectors—key contributors to plastic waste management—are not included in the EPR framework, which limits their incentives and support.
Recommendations for Improvement:
- Incorporate the Informal Sector:
- Recognize informal waste collectors and waste management agencies in the EPR framework to improve traceability and ensure better waste management.
- Eliminate Fraudulent Practices:
- Strict actions need to be taken against fraudulent recyclers and fake certificate issuers to restore credibility to the EPR system.
- Establish Fair Pricing for EPR Certificates:
- Undertake baseline cost studies to determine the true costs of plastic waste management, ensuring fair pricing for recycling certificates and preventing undervaluation.
- Standardize Packaging:
- Focus on product standardization to ensure that packaging materials are uniform and easily recyclable.
- Strengthen Monitoring:
- Improve oversight on the registration process and ensure that all polluters (producers, importers, brand owners) comply with the system’s guidelines.
EPR and Plastic Waste Management: Context and Importance
- Extended Producer Responsibility (EPR) is a policy approach where the responsibility of managing the entire lifecycle of plastic products (from production to disposal) lies with the producer.
- It is an essential part of India’s Plastic Waste Management Rules (2016), which mandate the recycling and proper disposal of plastic packaging waste.
Key Elements of EPR:
- Producer Accountability: Producers are responsible for the take-back, recycling, and final disposal of plastic packaging.
- Waste Minimization: Encourages reducing waste at the source by promoting sustainable packaging designs.
- Lifecycle Approach: Considers the entire lifecycle of the product, focusing on sustainability from production to disposal.
- Polluter Pays Principle: Ensures that the cost of waste management is borne by those responsible for generating the waste.

What is a Black Hole Triple System?
- Black Hole and Two Stars: Unlike typical binary systems (comprising a black hole and one other object), this system contains a black hole surrounded by two stars, one nearby and one far away.
- V404 Cygni: The central black hole in the system is the V404 Cygni, one of the oldest known black holes, roughly 9 times the mass of the Sun.
Significance of the Discovery:
- Questions on Black Hole Formation: The discovery raises new questions about how black holes are formed. Traditionally, black holes are thought to form after the explosion of a massive star (supernova), but this system does not follow that model.
- New Formation Theory: Researchers suggest the black hole may have formed via a "direct collapse" process, where a star collapses into a black hole without undergoing a supernova explosion. This is referred to as a "failed supernova".
- In a failed supernova, the star's collapse happens too quickly for the explosive outer layers to be ejected, leading to the formation of a black hole without the typical violent explosion.
Implications for Other Binary Systems:
- The black hole’s gradual consumption of one of its stars may imply that some binary black hole systems could have originally been triple systems, with one star eventually being consumed by the black hole.
Research and Collaboration:
- Study: The discovery was made by researchers at California Institute of Technology (Caltech) and Massachusetts Institute of Technology (MIT).
- Published in: The findings were published in Nature in October 2024.
Additional Context:
- Distance: The system is about 8,000 light years away, which is vast but still observable with advanced telescopes.
- Mystery of the "Failed Supernova": The concept of a failed supernova offers new insights into the life cycle of massive stars and their transformation into black holes.

LiDAR (Light Detection and Ranging)
- 01 Nov 2024
In News:
LiDAR (Light Detection and Ranging) is a cutting-edge remote sensing technology that uses laser pulses to measure distances and create detailed 3D maps of Earth's surface. This technology has recently played a crucial role in discovering a lost Mayan city hidden under the dense Mexican jungle.
What is LiDAR?
- Definition: LiDAR is a remote sensing technology that uses pulsed laser light to measure distances and generate precise 3D models of Earth’s surface.
- Components: The system includes a laser, a scanner, and a GPS receiver. It is usually mounted on an aircraft to map large areas of terrain.
- Data Accuracy: LiDAR can create high-resolution 3D models with vertical accuracy up to 10 cm, making it highly precise for mapping ground elevation.
How LiDAR Works
- Laser Emission: LiDAR sends out rapid laser pulses toward the ground.
- Reflection: These pulses hit the Earth’s surface, reflecting off features like vegetation, buildings, and terrain.
- Measurement: The time it takes for the laser light to travel to the ground and back is measured, allowing the system to calculate the distance between the sensor and the surface.
- Point Cloud Data: The reflected light data is collected as a "point cloud", representing all the surfaces it hits, including trees, buildings, and other features.
- Refinement: This point cloud can be processed into a Digital Elevation Model (DEM), stripping away vegetation and structures to reveal the “bare earth,” which highlights features like roads, buildings, and hidden settlements.
Why LiDAR is Useful for Archaeologists
- Large-Scale Surveying: Traditional archaeological methods often involve labor-intensive fieldwork, such as walking over every square meter and manually cutting through thick vegetation. LiDAR, however, allows researchers to quickly survey vast areas of land, even through dense jungle, from the comfort of a lab.
- Visibility Under Vegetation: LiDAR’s ability to penetrate dense foliage and reveal features beneath the surface is a game changer. Even thick tree canopies that obscure the ground are no match for the laser pulses, which can pass through gaps to illuminate hidden structures.
The Discovery of the Lost Mayan City
- The City of Valeriana: Using publicly available LiDAR data from a forest monitoring project in 2013, archaeologist Luke Auld-Thomas discovered a lost Mayan city in Mexico’s Campeche region. The city, named Valeriana, had been hidden for centuries by the thick jungle.
- City Features: The city has all the hallmarks of a Classic Maya political capital, including:
- Multiple enclosed plazas
- Broad causeways
- Temple pyramids
- A ball court
- A reservoir formed by damming a seasonal watercourse
- Historical Significance: Valeriana is believed to date back before 150 CE and may have been a key political and cultural center in the Maya civilization.
Applications of LiDAR Beyond Archaeology
- Geography and Mapping: LiDAR is widely used to generate precise, three-dimensional data about the Earth’s surface, helping geographers and planners.
- Environmental Monitoring: It is also used in forest monitoring, flood risk assessment, and environmental conservation.
- Urban Planning and Engineering: Engineers use LiDAR for creating highly accurate topographical maps and planning infrastructure projects.

Nobel Prize in Physiology or Medicine 2024: MicroRNA Research
- 08 Oct 2024
Overview
The 2024 Nobel Prize in Physiology or Medicine was awarded to Victor Ambros and Gary Ruvkun for their groundbreaking discovery of microRNA and its crucial role in post-transcriptional gene regulation. This award highlights their individual contributions to understanding how microRNAs influence gene expression, significantly advancing the field of molecular biology.
What are MicroRNAs?
MicroRNAs (miRNAs) are small, non-coding RNA molecules typically 19-24 nucleotides long. They regulate protein production by interacting with messenger RNA (mRNA), ultimately influencing how much protein is synthesized from genetic information.
The Process of Gene Regulation
Gene expression involves two primary steps:
- Transcription: DNA is copied into mRNA in the nucleus.
- Translation: mRNA is translated into proteins by ribosomes with the help of transfer RNA (tRNA).
MicroRNAs play a critical role in regulating this process, particularly after transcription, by silencing mRNA and thereby controlling protein production.
Pioneering Research
Background
In the late 1980s, Ambros and Ruvkun utilized the model organism Caenorhabditis elegans, a small roundworm, to explore developmental processes. They focused on mutant strains, lin-4 and lin-14, which displayed abnormal development.
Key Discoveries
- Victor Ambros: Ambros cloned the lin-4 gene and discovered that it produced a short RNA molecule that did not code for proteins. This finding suggested that lin-4 could inhibit lin-14’s activity.
- Gary Ruvkun: Ruvkun investigated the regulation of the lin-14 gene and determined that lin-4 did not prevent the production of lin-14 mRNA. Instead, it inhibited protein production later in the gene expression process. He identified crucial segments in lin-14 mRNA essential for its inhibition by lin-4.
Collaborative Findings
Their subsequent experiments demonstrated that lin-4 microRNA binds to lin-14 mRNA, effectively blocking the production of lin-14 protein. Their findings were published in 1993 and laid the foundation for the understanding of microRNA.
Impact and Recognition
Initially, the significance of their discoveries was not widely recognized, as it was thought that microRNA regulation was specific to C. elegans. However, Ruvkun’s later identification of the let-7 gene, a microRNA found in various animal species, broadened the understanding of microRNAs' universal role in gene regulation.
Current Understanding
Today, it is known that humans possess over a thousand genes that code for different microRNAs. These molecules are crucial in regulating gene expression across multicellular organisms.
Applications and Future Directions
MicroRNAs can fine-tune gene expression, influencing various cellular functions despite similar genetic backgrounds. Abnormal microRNA regulation has been linked to diseases such as cancer and genetic disorders. While the Nobel Committee acknowledged that practical applications of miRNA research are still developing, understanding these molecules is vital for future research and therapeutic advancements.

New Target for Cancer Treatment Discovered by IACS Scientists
- 01 Sep 2024
In News:
In a significant breakthrough, scientists at the Indian Association for the Cultivation of Science (IACS) in Kolkata have identified a new target for cancer therapy. Their study, recently published in The EMBO Journal, focuses on how cancer cells manage DNA repair during cell division, potentially paving the way for more effective treatments.
Key Findings
The researchers explored how cancer cells respond to topoisomerase 1 (Top1)-targeted chemotherapy. Top1 inhibitors, such as camptothecin, topotecan, and irinotecan, disrupt DNA replication and transcription, causing damage that usually leads to cell death. However, cancer cells can sometimes develop resistance by employing internal DNA repair mechanisms, primarily involving a protein called TDP1.
Mechanism of Action
Top1 is crucial for relaxing DNA supercoils during cell division, a process necessary for accurate chromosome segregation. Drugs targeting Top1 can kill cancer cells by preventing this relaxation. Nonetheless, cancer cells counteract this damage with TDP1, which repairs the DNA and promotes cell survival.
The IACS team discovered that TDP1's function is influenced by its phosphorylation status, which changes during the cell cycle and drug treatment. This modification helps TDP1 detach from chromosomes during cell division, a mechanism that helps cells survive despite the presence of chemotherapy drugs.
Novel Therapeutic Approach
The researchers propose a novel approach that combines inhibitors of two key molecules: CDK1 protein and TDP1 enzyme. CDK1 plays a critical role in regulating the cell cycle, while TDP1 is involved in repairing DNA damage. By inhibiting both, the researchers aim to disrupt the cancer cell's ability to repair DNA damage caused by Top1 inhibitors.
This combinatorial targeting strategy could enhance the effectiveness of cancer treatments. While Top1 inhibitors induce DNA damage, CDK1 inhibitors could prevent the repair of this damage or halt the cell cycle, making it difficult for cancer cells to survive. This dual-target approach may also help overcome resistance mechanisms that cancer cells develop against single-agent therapies.
Clinical Implications
CDK1 inhibitors, including avotaciclib, alvocidib, roniciclib, riviciclib, and dinaciclib, are currently in various stages of clinical trials. These drugs can be used alone or in combination with other DNA-damaging agents. Combining CDK1 inhibitors with Top1 inhibitors holds promise for significantly improving cancer treatment outcomes by targeting different aspects of the cell cycle and DNA replication.
Although the study was conducted using human breast cancer cells, the findings suggest potential benefits for patients with other types of cancer, such as ovarian, colorectal, and small cell lung cancers (SCLC). SCLC, in particular, is associated with tobacco smoking and could potentially benefit from this new combinatorial approach.
Conclusion
The IACS study opens new possibilities for cancer treatment by targeting DNA repair mechanisms in cancer cells. By combining CDK1 and Top1 inhibitors, the researchers aim to enhance the effectiveness of chemotherapy and overcome resistance. Further research, including clinical trials, will be essential to validate these findings and develop personalized cancer therapies that could improve patient outcomes across various cancer types.

EARTH TO EXPERIENCE A TEMPORARY 'MINI-MOON' IN SEPTEMBER
- 20 Sep 2024
In News:
In late September, Earth will temporarily capture a small asteroid known as 2024 PT5. This phenomenon, where an asteroid becomes a "mini-moon," will last for about two months before the asteroid escapes back into space. While Earth has gained mini-moons before, such occurrences are quite rare; most asteroids either miss the planet entirely or burn up upon entering the atmosphere.
What Is a 'Mini-Moon'?
Mini-moons are small asteroids that get temporarily captured by Earth's gravity, orbiting the planet for a limited time. These asteroids are typically small and difficult to detect—only four mini-moons have been identified in Earth's history, and none remain in orbit today. Some objects previously thought to be mini-moons were later determined to be space debris, including rocket stages and satellites.
Details About 2024 PT5
Discovered on August 7 through the NASA-funded Asteroid Terrestrial-impact Last Alert System (ATLAS), 2024 PT5 measures approximately 33 feet in length, making it invisible to the naked eye and standard amateur telescopes. However, it is detectable by professional astronomical equipment.
According to Carlos de la Fuente Marcos, a professor at the Complutense University of Madrid, 2024 PT5 originates from the Arjuna asteroid belt, which consists of space rocks that share similar orbits with Earth. There is also speculation that it could be a fragment resulting from an impact on the moon, as noted by Paul Chodas from NASA's Jet Propulsion Laboratory (JPL).
However, some experts argue that 2024 PT5 may not fully qualify as a mini-moon. For an asteroid to be classified as such, it must complete at least one full orbit around Earth. Instead, 2024 PT5 will follow a horseshoe-shaped path, leading Lance Benner, a principal investigator at JPL, to express skepticism about its classification as a mini-moon.
Significance of the Event
Studying 2024 PT5 will provide valuable insights into asteroids that pass near Earth and their potential for future collisions. Additionally, many asteroids are believed to contain precious minerals and water, which could be harvested for future space missions and resource utilization. Observing this mini-moon will enhance our understanding of these celestial bodies and their behavior in Earth's vicinity.

NEUROMORPHIC COMPUTING
- 14 Sep 2024
Indian Researchers Advance Neuromorphic Computing with Innovative Molecular Film
Researchers at the Indian Institute of Science (IISc) have made a groundbreaking development in neuromorphic computing, creating an analog computing system that leverages molecular films. This new system can store and process data across 16,500 different states, a significant leap from conventional binary computing methods.
Understanding Neuromorphic Computing
Neuromorphic computing is an advanced computing paradigm designed to emulate the structure and function of the human brain. By using artificial neurons and synapses, this approach marks a departure from traditional binary computing, enabling systems to learn and adapt from their environments.
How Neuromorphic Computing Works
Neuromorphic computing relies on Artificial Neural Networks (ANNs), which consist of millions of artificial neurons similar to those found in the human brain. These neurons communicate through electrical spikes or signals, following the principles of Spiking Neural Networks (SNNs). This setup allows the system to replicate the brain’s neuro-biological networks, performing tasks such as visual recognition and data interpretation with high efficiency.
Key Features of Neuromorphic Systems
- Brain-Inspired Architecture: Neuromorphic systems mimic the brain's structure, particularly the neocortex, which is involved in higher cognitive functions like sensory perception and motor commands.
- Spiking Neural Networks: These networks use spiking neurons that interact through electrical signals, mirroring the behavior of biological neurons. This design facilitates parallel processing and real-time learning.
- Integrated Memory and Processing: Unlike traditional von Neumann architecture, which separates memory and processing functions, neuromorphic systems combine these functions, leading to improved computational efficiency.
Advantages of Neuromorphic Computing
- Enhanced Efficiency: Neuromorphic computing enables faster problem-solving, pattern recognition, and decision-making compared to conventional systems.
- Revolutionizing AI Hardware: It holds the potential to transform AI hardware, allowing for complex tasks, such as training Large Language Models (LLMs), to be performed on personal devices. This advancement addresses current limitations related to hardware resources and energy efficiency.
- Energy Efficiency: Current AI tools are confined to data centers due to their high energy demands. Neuromorphic computing could overcome these constraints by providing energy-efficient hardware solutions.
Integration with Molecular Films
Molecular films, ultrathin layers engineered with specific electrical and optical properties, are central to this new advancement. These films act as neuromorphic accelerators, enhancing data storage and processing capabilities. They simulate brain-like parallel processing, improving performance in tasks such as matrix multiplication.
The recent development involves a molecular film that supports 16,500 possible states, a significant advancement over traditional binary systems. This film uses molecular and ionic movements to represent memory states, mapped through precise electrical pulses, creating what can be described as a "molecular diary" of states.
Comparison with Traditional Computing
- Parallel Processing: Neuromorphic computers can handle multiple streams of information simultaneously, unlike traditional computers that process data sequentially.
- Energy Efficiency: These systems consume less power by computing only when relevant events occur, making them suitable for real-time data processing applications.
- Analog vs. Binary: Traditional binary computing operates with bits that are either 0 or 1, akin to a light switch being on or off. In contrast, analog computing involves continuous values, similar to a dimmer switch with varying brightness levels.
This breakthrough by IISc researchers signifies a major step forward in neuromorphic computing, potentially transforming the way we approach data processing and artificial intelligence.
What is Helium & why is it used in rockets?
- 14 Sep 2024
The Crucial Role of Helium in Space Missions and the Challenges It Presents
Two NASA astronauts aboard Boeing’s Starliner will extend their stay on the International Space Station (ISS) due to issues with the spacecraft’s propulsion system, which includes problematic helium leaks. Meanwhile, SpaceX’s Polaris Dawn mission, which successfully launched on Tuesday, experienced delays due to similar helium-related issues with ground equipment.
The Importance of Helium in Spacecraft
Helium plays a critical role in space missions for several reasons. As an inert gas, it does not react with other substances or combust, which is crucial for maintaining the safety and stability of rocket systems. With an atomic number of 2, helium is the second lightest element after hydrogen. Its lightweight nature is essential for reducing the overall mass of rockets, which in turn minimizes fuel consumption and the need for more powerful (and costly) engines.
A key property of helium is its extremely low boiling point of –268.9 degrees Celsius. This allows it to remain in a gaseous state even in the super-cold environments where many rocket fuels are stored.
How Helium Is Utilized in Spacecraft
In spacecraft, helium is primarily used for:
- Pressurizing Fuel Tanks: Helium ensures that fuel flows smoothly to the rocket’s engines. As fuel and oxidizer are consumed during launch, helium fills the empty space in the tanks, maintaining consistent pressure.
- Cooling Systems: Helium is also used in cooling systems to manage the temperature of various components, preventing overheating and ensuring the proper functioning of the spacecraft.
Due to its non-reactive nature, helium can safely interact with the residual contents of the tanks without causing adverse reactions.
The Challenge of Helium Leaks
Despite its advantages, helium is prone to leakage. Its small atomic size and low molecular weight allow helium atoms to escape through even minor gaps or seals in storage tanks and fuel systems. This characteristic poses a significant challenge for space missions.
On Earth, helium leaks are easier to detect due to the gas’s rarity in the atmosphere. This makes helium a valuable tool for identifying potential faults in rocket or spacecraft fuel systems. The frequency of these leaks across various space missions, including those by ISRO and ESA, underscores a broader industry need for improved valve designs and more precise tightening mechanisms.

Polaris Dawn Mission: First Private Spacewalk Attempt
- 11 Sep 2024
Recently, a SpaceX Falcon 9 rocket launched from Florida, carrying American billionaire Jared Isaacman and three other astronauts into orbit for the Polaris Dawn mission. This five-day mission marks a milestone as it aims to achieve the world’s first private spacewalk. Polaris Dawn is the inaugural flight of the Polaris Program, a collaborative effort between Isaacman and SpaceX, led by Elon Musk. The program's goal is to develop innovative technologies for future Mars missions.
What is a Spacewalk?
A spacewalk, or “extravehicular activity” (EVA), involves an astronaut conducting activities outside a spacecraft while in space. The concept of a spacewalk dates back to March 18, 1965, when Soviet cosmonaut Alexei Leonov performed the first EVA during the Space Race. Leonov's spacewalk lasted just 10 minutes.
Modern spacewalks typically occur outside the International Space Station (ISS) and can last between five and eight hours. Astronauts conduct spacewalks for various purposes, such as performing scientific experiments, testing new equipment, or repairing satellites and spacecraft.
During a spacewalk, astronauts wear specially designed spacesuits and use safety tethers to prevent floating away into space. These tethers have one end attached to the astronaut and the other secured to the spacecraft. An alternative safety device is the SAFER (Simplified Aid for EVA Rescue), a backpack with small jet thrusters controlled by a joystick, which helps astronauts maneuver in space.
Objectives of the Polaris Dawn Mission
The Polaris Dawn mission, utilizing SpaceX’s Dragon capsule, aims to reach an altitude of approximately 1,400 km from Earth. This altitude exceeds the previous record set by NASA’s Gemini XI mission in 1966, which reached 1,372 km. At this height, the mission will be deep within the Van Allen radiation belts, which start around 1,000 km altitude and are known for their high levels of radiation. The crew will study the effects of spaceflight and radiation on human health.
Following this high-altitude phase, the Dragon capsule will descend to a lower orbit to facilitate the spacewalk scheduled for the third day of the mission, Thursday. During the spacewalk, the capsule will be depressurized, and the hatch will open, exposing the interior to the vacuum of space. Only two crew members, Isaacman and Gillis, will exit the capsule, while Poteet and Menon will remain inside to manage safety tethers and monitor the mission’s status.
The primary objective of the spacewalk is to test SpaceX’s newly developed EVA spacesuits. These suits, designed specifically for this mission, feature built-in cameras and heads-up displays to provide real-time information about the suit's condition. They also incorporate advanced thermal management systems.
After the spacewalk, Isaacman and Gillis will return to the capsule, which will then be repressurized before resuming its mission activities.
Additional Mission Activities
Throughout the mission, the crew will conduct 40 scientific experiments. These include attempting to capture X-ray images using natural space radiation instead of traditional X-ray equipment. The mission will also test SpaceX’s Starlink satellite network for laser-based communication, allowing satellite-to-satellite communication without relying on ground-based infrastructure.

Plunging Region of a Black Hole
- 18 May 2024
Why is it in the News?
For the first time, astronomers have observed the area right at the edge of a black hole where matter stops orbiting and plunges straight in at near-light speed.
What is the Plunging Region of a Black Hole?
- The plunging region of a black hole is an area where matter ceases to orbit the celestial object and instead falls directly into its incalculable depths.
- This phenomenon was initially predicted by Albert Einstein's groundbreaking theory of general relativity, which continues to shape our understanding of the cosmos.
- As matter approaches a black hole, it is torn apart and forms a rotating ring known as an accretion disc.
- According to general relativity, there exists an inner boundary within this disc, beyond which nothing can maintain its orbit around the black hole.
- Instead, the material is drawn towards the black hole at nearly the speed of light, marking the beginning of the plunging region.
- This region, situated just outside the event horizon, represents the point of no return for matter falling into a black hole.
- Despite the challenges posed by studying these enigmatic structures, researchers believe that investigating plunging regions could unveil new insights into the formation and evolution of black holes.
- Additionally, these studies may offer valuable information about the fundamental properties of space-time, potentially transforming our understanding of the universe and its most mysterious inhabitants.
What is a Black Hole?
- A black hole is a celestial phenomenon that arises from the remnants of a massive star that has exhausted its nuclear fuel and undergone gravitational collapse.
- It is characterized by an unfathomably dense core, known as a singularity, which is enveloped by a boundary called the event horizon.
- The event horizon serves as a point of no return; any matter or light that crosses this boundary is irrevocably drawn towards the singularity, making it impossible to escape the immense gravitational pull.
Black holes are classified into three categories based on their size and formation process:
- Stellar-mass black holes: These form when a massive star collapses at the end of its life cycle. They typically have masses ranging from approximately five to several dozen times that of our Sun.
- Supermassive black holes: Found at the centre of most galaxies, including our own Milky Way, these colossal structures boast masses that can reach billions of times the mass of the Sun.
- Intermediate-mass black holes: With masses between those of stellar mass and supermassive black holes, these entities are thought to form through the merger of smaller black holes or the collapse of dense clusters of stars.
- Due to their extreme nature, black holes have been the subject of extensive research and fascination in the scientific community.
- The study of these enigmatic structures continues to yield invaluable insights into the fundamental principles governing our universe.
Maillard Reaction
- 10 May 2024
Why is it in the News?
The Maillard Reaction elucidates the intricate chemical processes responsible for the diverse array of flavours, aromas, and textures found in foods.
What is Maillard's Reaction?
- The Maillard reaction is a complex chain of chemical reactions that occurs when heat is exposed to amino acids and reducing sugars.
- The Maillard Reaction, named after the French scientist Louis-Camille Maillard, is a chemical phenomenon observed when amino acids, essential components of proteins, and sugars undergo heating.
- This reaction influences the taste, scent, and consistency of food items.
- It characterizes a non-enzymatic browning process in food, where colour alterations manifest without the involvement of enzymes.
How does the Maillard Reaction Induce Browning in Food?
- The Maillard reaction initiates a complex chemical process that yields various products. Chemist J.E. Hodge first delineated its steps in 1953 to simplify its understanding.
- An array of foods, from meats to bread to vegetables and coffee beans, contain both sugars and protein components.
- When subjected to heat, these sugars and proteins undergo a condensation reaction, forming an unstable compound known as Schiff base.
- This Schiff base undergoes rearrangement and dehydration, yielding diverse intermediate compounds.
- These intermediates further react to generate essential flavour components, enriching the food's aroma.
- Some intermediates undergo rearrangement, resulting in a more stable product. These products serve as vital precursors to melanoidins, pivotal in imparting the food's characteristic brown hue.
- Continued transformation, including condensation and polymerization, culminates in the formation of melanoidins—nitrogen-containing compounds responsible for the food's distinctive brown colouration.
What are the Factors Affecting the Reaction?
- The pace and magnitude of the Maillard reaction hinge on various elements, including temperature, acidity, moisture levels, and the composition of proteins and sugars in the food.
- Optimal Temperature: Temperatures typically fall within the range of 110 to 170 degrees Celsius, with levels surpassing this threshold potentially resulting in food burning and imparting bitter flavours.
- Elevated temperatures generally expedite the reaction, whereas acidic environments and moisture content can impede it.
- Hence, foods tend to brown more rapidly at higher temperatures, and dry items like bread crusts often acquire a rich brown hue during baking.

Pontus Tectonic Plate: Geologist Unexpectedly Finds Remnants of a Lost Mega-Plate (Science Daily)
- 10 Oct 2023
Why in the News?
Geologists have reconstructed a massive and previously unknown tectonic plate that was once one-quarter the size of the Pacific Ocean.
About Pontus Tectonic Plate:
- Recently discovered in the west Pacific Ocean, the Pontus Tectonic Plate is a long-lost geological plate that holds significance in Earth's history.
- Believed to have measured about 15 million square miles at its zenith, roughly equivalent to one-quarter of the Pacific Ocean, this massive tectonic plate dates back as far as 160 million years, with more recent traces extending to approximately 20 million years ago.
- Over millions of years, the Pontus Plate underwent a gradual subduction process, pulled downward beneath a neighbouring plate by the force of gravity.
How was this Discovery Made?
- The subducting process involves the plate sinking into Earth's mantle due to its higher density compared to the surrounding mantle.
- Traces of a subducted plate are discernible in the form of rock fragments concealed in mountain belts.
- During subduction, upper portions of the plate are occasionally scraped off.
- Researchers employed geological data and computer modelling to reconstruct the movements of current plates, revealing a substantial area potentially vacated by the subducted Pontus Plate.
- Utilizing magnetic techniques, scientists identified basalt remnants in Borneo as Pontus relics, suggesting that this fragmentary evidence was left behind during the plate's subduction some 85 million years ago.
What is Plate Tectonics?
- Tectonic plates are large, rigid pieces of Earth's lithosphere, the outer shell comprising the crust and uppermost part of the mantle.
- These plates, which vary in size and shape, constantly move and interact, shaping the Earth's dynamic surface.
- The Earth's lithosphere is divided into several major plates, such as the Pacific, North American, and Eurasian plates, among others.
- The interactions at plate boundaries result in various geological phenomena, including earthquakes, volcanic eruptions, and the formation of mountain ranges.
- Plate tectonics, the theory explaining these movements, underscores how heat-driven convective currents in the Earth's mantle cause plates to diverge, converge, or slide past each other.
