Centrifuge Process of Uranium Enrichment: Uranium Enrichment is used to increase U-235 concentration to the desired level. Natural uranium has 99.3% U-238 and 0.7% U-235. Nuclear reactors require 3–20% U-235, while nuclear weapons require about 90% U-235. Uranium enriched beyond 20% is considered as highly enriched. In this method, uranium is first converted into a […]

Biomass Satellite Mission: The European Space Agency (ESA) will launch the Biomass satellite mission in end of April, 2025, aboard the Vega C rocket. Biomass is ESA’s seventh Earth Explorer satellite mission under its climate and Earth systems programme. It will map global forests and measure carbon levels to assess forest health and its role […]

ZooWIN Portal: The Union Health Ministry recently launched the ZooWIN portal to monitor the availability of anti-rabies and anti-snake venom vaccines in real time. ZooWIN (Zoonoses-WIN) is a digital portal to monitor stocks of Anti-Rabies Vaccine (ARV) and Anti-Snake Venom (ASV) across India. It ensures better coordination among healthcare systems, especially in rural and underserved […]

River Blindness: Zoological Survey of India (ZSI) study on blackflies offers hope for river blindness control, Researchers worked on four species collected from eight locations in the central Himalayan region A new study by the Zoological Survey of India (ZSI) has introduced DNA barcoding to accurately identify blackfly species—the carriers of Onchocerca volvulus, the parasitic […]

Hadean Protocrust: A new international study led by Macquarie University, Australia, suggests that the chemical signatures attributed to plate tectonics were already present in the Hadean protocrust. The Hadean protocrust refers to the earliest known crust of the Earth—its outermost solid layer—that formed during the Hadean aeon, the planet’s first geologic era, which began around […]

Semaglutide: A recent international, multicentre clinical study has found that semaglutide, a medication primarily used to treat type 2 diabetes and obesity, can reduce the risk of major cardiovascular events by 14%. Semaglutide is a glucagon-like peptide-1 receptor agonist (GLP-1 RA). It mimics GLP-1, a natural hormone that helps regulate blood sugar and appetite. It […]

CAPTCHA Systems: CAPTCHA systems are once again in focus as debates arise over their role in the recent surge of bot activity and digital security breaches, highlighting both their importance and limitations in today’s evolving cyber landscape. CAPTCHA stands for “Completely Automated Public Turing test to tell Computers and Humans Apart.” It is a human […]

Project Varsha: India is set to commission its first dedicated nuclear submarine base, INS Varsha, in Andhra Pradesh in 2026, as part of Project Varsha, and plans to operationalise its third nuclear-powered submarine, INS Aridhaman. Project Varsha A classified naval infrastructure project launched by the Indian Navy to build INS Varsha, a state-of-the-art nuclear submarine […]

Excise Duty Hiked on Petrol and Diesel: Central Government of India announced an increase in excise duties on petrol and diesel by ₹2 per litre each. According to a notification by the Revenue Department under the Ministry of Finance, the new excise duty on petrol is now ₹13/litre and ₹10/litre on diesel. Despite the duty […]

Kazakhstan’s Major Rare Earth Elements Are Discovered: Kazakhstan has uncovered its largest-ever reserve of rare earth metals at the Kuirektykol site in the Karaganda region, marking a transformative moment for the country’s mining industry and its position on the global resource map. With nearly one million tons of rare earth elements (REEs) and potential reserves […]
