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 […]

Archaeologists Discover Evidence of “Brands” 3,200 Years Before Modern Capitalism
Researchers found that brands existed long before modern capitalism. Long before modern corporations and capitalism, craftspeople may already have been producing goods with a recognizable identity that traveled far beyond their place of origin. An international team led by Marta Luciani of the University of Vienna has found evidence that distinctive painted pottery made in […]
“Zombie” Cells Reveal a Surprising New Driver of Chronic Inflammation
Dysfunctional mitochondria may drive age-related inflammation by helping switch on inflammatory genes, and blocking SLC25A1 reduced that activity. As people age, senescent cells accumulate in the body. These so-called “zombie” cells have stopped dividing but remain metabolically active, releasing inflammatory molecules that can contribute to persistent inflammation associated with frailty, cardiovascular disease, cancer, neurodegeneration, and […]
