Sustainable Aviation Fuel (SAF), also known as ‘aviation biofuel’, shares similar chemical and physical characteristics with Aviation Turbine Fuel (ATF). It can be sourced from municipal solid waste, oils and fats (such as oilseeds and algae oils), agricultural residues (including Sugarcane bagasse, husk, and corn), and wood wastes. It can also be produced artificially using a method that collects carbon out of the air. Benefits of SAF: Green […]

Why in the news? The OTOF gene is the primary target for the breakthrough gene therapies recently reported in 2026. Gene Replacement: Because the deafness is caused by a single missing protein, scientists can use a viral vector (like a microscopic delivery truck) to carry a healthy version of the OTOF gene into the ear. […]

Why in News ? The Prototype Fast Breeder Reactor (PFBR) at Kalpakkam, Tamil Nadu, has achieved “criticality.” * Criticality Simplified: Think of it like successfully starting a car engine for the first time. It means the nuclear reactor has started a self-sustaining chain reaction. It doesn’t need an outside “spark” anymore; it is now running […]

About Semaglutide: 1. Mechanism of Action Semaglutide belongs to a class of drugs called GLP-1 Receptor Agonists (Glucagon-like Peptide-1). It mimics a natural hormone produced in the gut. Insulin Regulation: It tells the pancreas to release more insulin when blood sugar is high. Glucagon Suppression: It stops the liver from making too much sugar. Gastric […]

The Somato-Cognitive Action Network (SCAN) is a recently discovered brain network that links thinking (cognition), body sensations, and movement (action) into one integrated system. What exactly is SCAN? Location: It is located mainly in the primary motor cortex (M1), positioned between areas controlling specific body parts (like the hand, foot, or mouth). Whole-Body Control: Unlike […]

Why in News? A 2026 study (journal Clean Water) shows exRNA persists in disinfected drinking water, enabling identification of bacterial survival strategies post-disinfection. Opens scope for next-generation disinfectants and advances in non-invasive diagnostics (liquid biopsy). What is  Extracellular RNA (exRNA)? exRNA  refers to RNA molecules present outside cells, found in fluids like blood, saliva, urine, cerebrospinal fluid, and even treated water. […]
