An accidental Subaru Telescope image of a distant bare comet is giving astronomers a clearer look at the surface of a cometary nucleus. A comet can reveal its surface most clearly when it is still far from the Sun, before warming releases the gas and dust that normally hide its nucleus. Researchers found just such […]

JWST Finds Giant Planets Face a Cosmic Race Against Time
JWST observations of dozens of young, Sun-like stars suggest that the forces stripping gas from planet-forming disks evolve as the systems mature. Around young stars, the gas needed to build planets is steadily disappearing. New observations from NASA’s James Webb Space Telescope (JWST) are showing that this loss does not happen the same way throughout […]
Brain Cells Once Thought Protective May Actually Drive Cognitive Decline With Age
Age-related oligodendrocyte dysfunction may contribute to cognitive decline by disrupting myelin and large nerve fibers. Myelin is essential for fast communication in the brain, forming a protective coating around nerve fibers so electrical signals can travel efficiently. But the cells that produce this insulation, called oligodendrocytes, may become dysfunctional with age and actively contribute to […]

Magnetic Bacterium Extends Lifespan by 43% in Surprising Anti-Aging Study
A magnetotactic bacterium extended lifespan in worms by 43.39% and appeared to do so by suppressing ferroptosis. A bacterium best known for producing microscopic magnetic structures may have an unexpected effect on aging. In experiments with Caenorhabditis elegans, the magnetotactic bacterium Magnetospirillum magneticum AMB-1 extended average lifespan by 43.39% while helping preserve neurological function and […]
80,000-Year-Old Arrowheads Could Rewrite the Story of How Humans Reached Europe
Microlithic projectile points from Uzbekistan may link Central Asia to a revised story of Homo sapiens’ early expansion into Europe. Researchers have identified tiny triangular projectile points at the Obi Rakhmat site in Uzbekistan by studying the marks left when they struck targets. Found in the site’s oldest occupation layers, the points date back 80,000 […]
