People with Alzheimer’s disease who took the common supplement glucosamine were 25% more likely to die within five years than ...

Growing older affects every part of the body, including the brain. Many people notice changes in memory, concentration, and mental sharpness as they age. Scientists have long known that aging ...

Virginia Tech researchers have shown that memory loss in aging may be reversible. Using CRISPR tools, they corrected molecular disruptions in the hippocampus and amygdala, restoring memory in older ...

Researchers led by the Institute of Marine Research in Norway report an 800 km poleward shift in the spawning grounds of Norwegian spring-spawning herring (NSS herring) following a loss of collective ...

We become forgetful as we age. This is often seen as a universal truth, but in fact it is far from universal: some people remain incredibly sharp at 100 years old, while others experience memory loss ...

Researchers have reversed memory loss in aging mice by targeting a protein that builds up in brain cells, pointing toward a potential pathway to counter the cognitive declines of aging. In a new study ...

Stress is the brain’s natural response to fear, but it often disrupts memory in the process, potentially impacting the possibility of memory loss. When preparing for a big presentation or taking a ...

Some older adults develop the physical brain changes associated with Alzheimer’s disease but never experience memory loss or ...

Boston University professor and neuroscientist Steve Ramirez promoted his new book, which dives into his experiences with grief after the death of his research partner and explores the science of ...

Cancer can sometimes trigger an off-the-rails immune response that harms nerve cells, rapidly leading to thinking problems and memory loss — but until now, scientists weren't sure what caused this ...

In this figure, an intestinal immune cell detects medium-chain fatty acids produced by aging gut bacteria through the GPR84 receptor, releasing inflammatory molecules that block signaling along the ...
