A Hidden Cellular Process May Drive Aging and Disease

Feb. 4, 2026 As we age, our cells don’t just wear down—they reorganize. Researchers found that cells actively remodel a key structure called the endoplasmic reticulum, reducing protein-producing regions while ...

A Silent Brain Disease Can Quadruple Dementia Risk

Feb. 1, 2026 Researchers studying nearly 2 million older adults found that cerebral amyloid angiopathy sharply raises the risk of developing dementia. Within five years, people with the condition were far more ...

Alzheimer’s Scrambles Memories While the Brain Rests

Feb. 1, 2026 When the brain rests, it usually replays recent experiences to strengthen memory. Scientists found that in Alzheimer’s-like mice, this replay still occurs — but the signals are jumbled and poorly ...
