Researchers raised levels of the gene-regulating protein Sox9 in star-shaped support cells called astrocytes, triggering the brain to clear toxic amyloid plaques 'like a vacuum cleaner' and preserving memory in mice with established disease.
30-year project traces Renaissance genius through 21 generations, identifies living descendants, and excavates ancient family tomb for DNA analysis.
A rapid chemical reaction crosslinks red blood cells in seconds, producing engineered clots that stop massive bleeding and could remake battlefield trauma care, Nature reports.
Webb mapped polycyclic aromatic hydrocarbons in tiny pockets of the chemically primitive dwarf galaxy four million light-years away, rewriting models of how early-universe dust forms.
Massive genealogical effort traces family across 21 generations while excavations at ancient tomb could provide Renaissance master's genetic profile.
University of Warwick researchers confirm 31 new planets and identify thousands more candidates using machine learning analysis of NASA TESS data.
The RAVEN system confirmed 31 brand-new planets and identified thousands of candidates, including ultra-short-period worlds and mysterious 'Neptunian desert' inhabitants.
New research suggests the Cascadia subduction zone and San Andreas fault can trigger earthquakes within hours of each other, potentially hitting multiple cities simultaneously.
Researchers enhance Sox9 protein in astrocytes to help brain clear harmful plaques while preserving memory in mouse studies.
A team partially delivered Cassian Jouvert at 25 weeks, placed a fetal tracheostomy, and returned him to the womb to keep developing — a roadmap for one of the rarest fatal fetal conditions.
EGS-z11-R0 is large, regular and chemically enriched at a moment when galaxies are supposed to be small, blue and primordial — defying leading models of structure formation.
University of Melbourne engineering students recreate Sir William Hamilton's 1775 Mount Vesuvius simulation using modern LED technology and electronic systems.
Tanyka amnicola belonged to an ancient lineage that was already a 'living fossil' in its time, featuring unusual jaw structure with sideways-pointing teeth.
Tiny wall-dwelling predator helps control urban pests like mosquitoes and flies, raising questions about its mysterious Galápagos connection.
Tanyka amnicola, discovered in Brazilian riverbed, was a 'living fossil' even in its own time with unique sideways-pointing teeth for grinding plants.
First evidence of these prized compounds found in just one of three strains studied, revealing unexpected chemical diversity in cannabis plants.
Comprehensive review of 217 trials shows walking, cycling and swimming outperform other exercise types in reducing pain and improving function.
Researchers map millions of neurons in mice to uncover organized stripe patterns in smell receptors, solving a long-standing mystery about olfactory system organization.
Comprehensive review of 217 trials shows walking, cycling, and swimming outperform other exercise types in reducing pain and improving function for knee osteoarthritis patients.
Vasuki indicus lived 47 million years ago and could have stretched up to 49 feet long, making it one of the largest snakes ever discovered.
Named Vasuki indicus, the massive prehistoric serpent lived 47 million years ago in India and represents a unique lineage that originated on the subcontinent.
Modeling shows axion-like particles in a narrow mass window can trigger direct collapse of gas clouds into billion-solar-mass black holes — the kind James Webb keeps finding too early in cosmic history.
Fossil remains of Vasuki indicus from 47 million years ago reveal a massive serpent that stretched up to 49 feet in length.
The rover detected compounds resembling DNA building blocks in 3.5-billion-year-old rocks, suggesting Mars may have once been far more biologically promising than previously thought.
The variety of compounds includes DNA-like building blocks preserved in 3.5-billion-year-old rocks, suggesting Mars was once more biologically promising.
After more than two years of investigation, researchers identify the strange object found 2 miles deep as remains from a giant sea anemone.
Powerful synchrotron X-rays uncover preserved blood vessels in 66-million-year-old Tyrannosaurus rex rib, providing new insights into dinosaur biology and recovery.
Genetic research challenges single-population theory, showing early humans evolved from multiple intermingling groups across Africa over hundreds of thousands of years.
New research suggests EPA, a key omega-3 fatty acid, could interfere with blood vessel healing and contribute to cognitive decline.
