NOSE DETECTS ALZHEIMER’S YEARS BEFORE MEMORY LOSS
YOUR NOSE DETECTS ALZHEIMER’S YEARS BEFORE MEMORY LOSS NEW DELHI: Researchers have uncovered why smell often fades early in Alzheimer’s: the brain’s immune cells dismantle key nerve connections between the olfactory bulb and brainstem. Membrane changes in neurons send an “eat-me” signal to microglia, which mistakenly destroy them. Evidence from mice, human tissue, and PET […]
PATCH MONITORS HEALTH WITHOUT DRAWING BLOOD
PATCH MONITORS HEALTH WITHOUT DRAWING BLOOD NEW DELHI: Researchers have developed a self-powered microneedle patch to monitor a range of health biomarkers without drawing blood or relying on batteries or external devices. In proof-of-concept testing with synthetic skin, the researchers demonstrated that the patches could collect biomarker samples over periods ranging from 15 minutes to […]
LIVING HEART VALVES TO HELP TREAT MANY
LIVING HEART VALVES TO HELP TREAT MANY HEART CONDITIONS OF KIDS NEW DELHI: A procedure which uses living heart valves may have expanded application as a treatment for various types of paediatric heart valve conditions. The research was led by pediatric heart specialists at Duke Health. It looked at 19 children with various heart conditions […]
“BLOOD MOON” LUNAR ECLIPSES OF THE DECADE TODAY
TOTAL LUNAR ECLIPSE ON SEPT 7: VISIBLE IN INDIA NEW DELHI: There will be a total lunar eclipse on September 7, visible in many parts of India from 8.58 PM IST and it ends at 2.25 AM. The eclipse will be visible in India, including major cities like Delhi, Mumbai, Kolkata, Hyderabad, Pune, Lucknow, Bengaluru, […]
A 4-IN-1 BREAKTHROUGH FOR LASTING WEIGHT LOSS
NEW DELHI: Scientists are racing to improve weight loss treatments beyond drugs like Ozempic and Wegovy, which are effective but plagued by nausea, bone loss, and weight regain. Tufts University chemists have created a new multi-target compound that goes beyond the usual GLP-1, GIP, and glucagon approaches by adding a fourth hormone, PYY. This “quadruple-action” […]
BIASED AI CHATBOTS CAN SWAY PEOPLE’S POLITICAL VIEWS IN MINUTES
BIASED AI CHATBOTS CAN SWAY PEOPLE’S POLITICAL VIEWS IN MINUTES NEW DELHI: In a new study, biased AI chatbots swayed people’s political views with just a few messages. If you’ve interacted with an artificial intelligence chatbot, you’ve likely realized that all AI models are biased. They were trained on enormous corpuses of unruly data and […]
RESEARCH: WORLD PEOPLE PREFER SELF-RELIANT STRATEGIES
MOST PEOPLE ‘GO IT ALONE’ TO MAKE TOUGH DECISIONS NEW DELHI: When faced with tough decisions, humans the world over prefer reflecting on their own rather than accepting advice or information from elsewhere, researchers report. In a study encompassing 13 languages, 12 research teams, and 12 countries over five continents, the same findings cut across […]
HIDDEN BRANCH IN HUMAN EVOLUTION
NEW DELHI: Fossils unearthed in Ethiopia are reshaping our view of human evolution. Instead of a straight march from ape-like ancestors to modern humans, researchers now see a tangled, branching tree with multiple species coexisting. Newly discovered teeth reveal a previously unknown species of Australopithecus that lived alongside some of the earliest Homo specimens nearly […]
FLAWS THAT MAKE ELECTRONICS FASTER, MORE EFFICIENT
NEW DELHI: Defects in spintronic materials, once seen as limitations, may now be key to progress. Chinese researchers discovered that imperfections can enhance orbital currents, unlocking more efficient, low-power devices that outperform traditional approaches. Scientists have turned a longstanding challenge in electronics — material defects — into a quantum-enhanced solution, paving the way for new-generation […]
A NEW WAY TO TURN SUNLIGHT INTO FUEL
NEW DELHI: A research team created a plant-inspired molecule that can store four charges using sunlight, a key step toward artificial photosynthesis. Unlike past attempts, it works with dimmer light, edging closer to real-world solar fuel production. A research team from the University of Basel, Switzerland, has developed a new molecule modeled on plant photosynthesis: […]
