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 […]

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 […]

Antimony: Pakistan reportedly discovered a massive cache of antimony in the conflict-torn region of Balochistan. Antimony is a chemical element with the symbol Sb and atomic number 51. Classified as a metalloid, antimony is a solid at room temperature. It exhibits poor electrical and heat conductivity Commercial forms of antimony are generally ingots, broken pieces, […]

Flouride : UP News The Uttar Pradesh Jal Nigam confirmed the presence of excessive fluoride in 120 hamlets, affecting nearly 2 lakh people. Some villages recorded fluoride levels of 2 mg/L or more, exceeding the safe limit of 1-1.5 mg/L. Fluoride is a naturally occurring element found in groundwater. The national drinking water limit for […]

Chandrayaan-3 ChaSTE: Chandrayaan-3’s Surface Thermophysical Experiment (ChaSTE) became the first instrument to measure in situ temperatures near the moon’s south pole. It successfully penetrated lunar soil and deployed a thermal probe, achieving what two previous missions—ESA’s Philae (2014) and NASA’s InSight HP3 (2018)—could not. This experiment provided crucial data on lunar surface temperatures, strengthening evidence […]

What are Synthetic Drugs? India is facing a surge in synthetic drug trafficking.
