Possible Extraterrestrial Life Detection: JWST data suggests potential signs of life on exoplanet K2-18b (124 light years away), specifically the detection of dimethyl sulphide (DMS), a gas primarily produced by living organisms on Earth.
Significance of DMS: The amount of DMS detected on K2-18b is far greater than Earth’s levels.
JWST’s Role: JWST, launched in December 2021, made these observations, highlighting
JWST’s Capabilities: JWST is the largest and most powerful space observatory, a collaboration between NASA, ESA, and CSA. It orbits the L2 Lagrange Point (1.5 million km beyond Earth).
Infrared Observation: JWST primarily observes in the infrared spectrum, enabling it to see through cosmic dust and view early galaxies, unlike the Hubble Telescope which observes in visible and ultraviolet light.
JWST’s Objectives: JWST studies the formation of stars, galaxies, and planetary systems, and it is analysing exoplanet atmospheres.
JWST Components: Key components include the Optical Telescope Element (OTE), Integrated Science Instrument Module (ISIM), Sunshield, and Spacecraft Bus.
Carbon-Bearing Minerals Discovered: Curiosity Rover found carbonate mineral siderite (containing carbon and oxygen) in Martian rocks. This marks the first solid evidence of a carbon cycle on Mars.
Discovery Location: The find was made in an ancient lakebed in the Gale Crater, during exploration of an 89-meter stretch of terrain.
Siderite’s Significance: The rocks contain 5-10% siderite, suggesting a significant amount of Mars’ past COâ‚‚ might be trapped in the crust.
Evidence of a Slow Carbon Cycle: The presence of iron oxyhydroxides indicates siderite may have dissolved in acidic water, releasing some COâ‚‚ back into the atmosphere. This points to a limited and slow carbon cycle.
Curiosity’s Mission: Launched in 2011 as part of the Mars Science Laboratory (MSL), Curiosity aims to determine if Mars ever had conditions suitable for life, study its climate, and analyze its geology.
Crater in 2012, an area believed to have once contained water.
Power Source: The rover runs on a thermoelectric power generator that uses the radioactive decay of plutonium, instead of solar panels.
Objectives: Determine whether life ever existed on Mars, Characterise Mars’ past and present climate, Understand the geology of Mars and Prepare for future human exploration.
V2G Technology: Enables EVs to discharge power back to the grid, acting as decentralized energy storage.
Pilot Project: Kerala, in collaboration with IIT Bombay, has launched a project to explore V2G implementation.
Modes:
Grid-to-Vehicle (G2V): Charging EVs from the grid.
Vehicle-to-Grid (V2G): Discharging EV power back to the grid.
Need: Supports renewable energy integration, enhances grid stability, provides emergency power, and offers decentralized storage.
Global Adoption: U.S., U.K., and Netherlands are leading in V2G adoption, compensating EV owners for supplying power during peak demand. California encourages participation in grid stability services.
India’s Status: Early stages, focusing on EV charging infrastructure. CEA has formed a committee on reverse charging. Current market structure not suited for V2G.
KSEB-IIT Bombay Project Goals: Assess EV’s ability to support the grid during peak demand when solar energy is unavailable.
Benefits for Utilities: Smart charging and V2G integration can turn EV charging from a challenge to an advantage. Encourages EV charging during high solar generation times.
Regulatory Changes Needed: Supportive changes are required to mainstream V2G in India, given the variable nature of renewable energy.
Decarbonization through RE: V2G enables EVs to act as a storage source for excess solar generation, which can be used at night, thus enabling decarbonization with RE.
Grid Stability: V2G can modulate EV battery power to reduce the impact of variable RE on the grid.
India to Host IBCA Headquarters: India will host the headquarters and secretariat of the International Big Cat Alliance (IBCA), solidifying its leadership role in global big cat conservation efforts.
Agreement Signed: An official agreement has been signed between India and the IBCA, establishing the legal framework for the headquarters’ operation. The agreement includes provisions for visas, privileges, and immunities for IBCA personnel and premises.
Financial Commitment: India has pledged ₹150 crore (approximately $18 million USD) from 2023-24 to 2028-29 to the IBCA. This funding will establish a corpus fund, build infrastructure, and cover recurring expenses.
IBCA Objectives: The IBCA aims to conserve seven major big cat species: Tiger, Lion, Leopard, Snow Leopard, Puma, Jaguar, and Cheetah.
Formal Establishment: The IBCA is now a treaty-based intergovernmental organization after ratification by five countries: India, Nicaragua, Eswatini, Somalia, and Liberia. India formally joined IBCA in September 2023. The alliance formally became a global legal entity after five signatory countries ratified the IBCA framework agreement.
Implementation Agency: The IBCA is implemented through the National Tiger Conservation Authority (NTCA), under the Ministry of Environment, Forest and Climate Change (MoEFCC).
Membership Open: Membership is open to all UN Member States, including range countries (where big cats naturally occur) and non-range countries interested in supporting conservation.
Combating Threats: The IBCA will address poaching, illegal wildlife trade, and habitat loss. The IBCA aims to foster transboundary cooperation among range countries for big cat conservation.
Leveraging Expertise: India will leverage its Project Tiger experience to lead research, training, and conservation financing initiatives under the IBCA.
Rising Accidents: Metro cities face increasing accidental deaths and injuries involving pedestrians, cyclists, and vendors due to misuse of service lanes by motor vehicles.
Active Mobility Defined: Active mobility involves human-powered transport (walking, cycling, skateboarding) and micro-mobility (e-bikes).
Policy Focus: Active mobility is gaining attention with initiatives like the National Transit Oriented Development (NTOD) policy and the Smart Cities Mission (SCM)
PETA’s core mission: To end abusive treatment of animals in business and society.
Support for Trump Administration: PETA is commending the Trump administration for its policy changes aimed at ending animal testing in federal research programs.
FDA Initiatives: PETA praises the FDA’s steps toward adopting more ethical testing methods, such as organoids.
Four Focus Areas: PETA concentrates its efforts on areas where animals suffer the most: laboratories, food industry, clothing trade, and entertainment.

Opposition to Speciesism: PETA opposes the human-supremacist worldview known as speciesism.
Official Recognition: Type 5 diabetes has been officially recognized by the International Diabetes Federation (IDF) at the 75th World Congress for Diabetes in Bangkok.
Definition: It affects lean, undernourished teenagers and young adults in low- and middle-income countries (LMICs).
Cause: Primarily caused by malnutrition-induced reduction in insulin production, unlike Type 2 diabetes which involves insulin resistance.
Pancreatic Function: Pancreatic beta cells function abnormally, resulting in severely reduced insulin secretion.
Historical Context: First reported in Jamaica in 1955 as J-type diabetes; WHO classified it as “malnutrition-related diabetes mellitus” in 1985 but removed it in 1999 due to a lack of causal evidence.
Global Prevalence: Estimated to affect about 25 million people globally, predominantly in the Global South (India, Sri Lanka, Bangladesh, Uganda, Ethiopia, Rwanda, Korea).
Key Markers:
Low BMI (<18.5 kg/m²)
Severely reduced insulin levels
Substantially lower body fat percentage
Inadequate dietary intake of protein, fibre, and micronutrients
No autoimmune or genetic causes
Malnutrition’s Role: Malnutrition, beginning in the womb, plays a critical role. Undernourishment during fetal development and early life can lead to Type 5 diabetes.
Treatment: Specific diagnostic criteria and therapeutic guidelines are still
being developed by the Type 5 Diabetes Working Group. Treatment involves a high protein diet and adequate carbs/fats to promote weight gain. Anti-diabetic medicine or insulin is considered on a case-by-case basis.
