Scientists uncovered how influenza A commandeers human cells, including a surprising strategy that dissolves tiny structures in the nucleus and releases proteins the virus may use to reproduce。 The detailed molecular map could reveal new drug targets and help researchers study dangerous flu strains such as H5N1
Researchers have uncovered a surprising culprit behind sleep loss in Alzheimer’s disease: the brain’s own immune cells。 In mice with amyloid plaques, overactive microglia triggered inflammation that kept the brain from getting enough deep, restorative sleep。 Temporarily removing most of these cells restored more than two hours of sleep per day, eve
Researchers discovered a proton-assisted mechanism that greatly improves how triplet energy moves between quantum dots and nearby molecules。 The proton briefly shifts position, helps coordinate electron movement, and then returns to where it started。 This quantum-driven shuttle could offer a powerful new way to tune solar cells, lasers, and catalyt
Miniature brain models grown from patients’ cells revealed striking differences in how Alzheimer’s-related tissue responds to an antidepressant。 The organoids and the particles they release could eventually guide more personalized treatments and provide new clues for diagnosing the disease
The longevity-linked APOE2 gene appears to protect brain cells by reducing DNA damage and helping neurons recover from stress。 The finding could open a new path toward treatments that mimic APOE2’s defenses in people at higher genetic risk for Alzheimer’s
A new experimental treatment may have found a way to outsmart glioblastoma’s toughest defense: the blood-brain barrier。 Researchers used sugar-coated nanoparticles to ferry genetic instructions that restore a key tumor-suppressing protein directly into brain cancer cells。 In mouse studies, the therapy increased median survival by 50% while shrinkin
A new review highlights exciting progress in atomically thin quantum materials where light and magnetism work together in ways never before possible。 In these materials, light-generated excitons can interact directly with magnetic behavior, creating opportunities to control magnetic states using light alone。 Scientists believe this could pave the w
A new particle detector called PLATON could replace millions of tiny detector components with a single block of light-producing material。 Using a light-field camera, highly sensitive photon sensors, and AI, it reconstructs particle paths in fast, detailed 3D。 Simulations suggest it could match or surpass today’s best detectors while being far easie
A new AI-powered blood test could give people a remarkably early warning of serious heart and circulation problems。 Developed by researchers at the University of Hong Kong, CardiOmicScore analyzes thousands of proteins and metabolites to estimate the risk of six major cardiovascular diseases, including heart attack, stroke, heart failure, and atria
NASA has chosen 41 commercial technology projects that could solve critical challenges for future missions to the Moon and Mars。 From powering lunar outposts to protecting spacecraft from Moon dust, the innovations are designed to push both space exploration and the commercial space economy forward
NASA is ramping up its lunar ambitions by awarding nearly $600 million for four commercial Moon landings planned for late 2028。 Each mission will carry the same trio of science instruments to improve lunar navigation, study dangerous dust kicked up during landings, and map the Moon's radiation environment。 The agency also revealed plans for new rov
NASA is preparing for future astronaut landings on the Moon with an unusually ambitious orbital rehearsal。 During Artemis III in 2027, Orion astronauts will rendezvous and dock separately with prototype lunar landers from Blue Origin and SpaceX, allowing crews and ground teams to test the complex maneuvers needed for later missions
