A next-generation drug tested in yeast was found to extend lifespan and slow aging by influencing a major growth-control pathway. Researchers also uncovered an unexpected role for agmatinases, enzymes that help keep this pathway in balance. Diet and ...

Regular consumption of polyphenol-rich foods like tea, coffee, berries, nuts, and whole grains may significantly support long-term heart health. A decade-long study of more than 3,100 adults found that those who consistently ate polyphenol-packed ...

A large study found that people with impaired kidneys tend to have higher Alzheimer's biomarkers, yet they don't face a higher overall risk of dementia. For those who already have elevated biomarkers, kidney problems may speed up when symptoms appear ...

Cedars-Sinai scientists have created a new experimental drug called TY1 that helps the body repair damaged DNA and restore injured tissue. The discovery came from studying tiny molecular messages released by heart cells that naturally support healing ...

Researchers found that people with anxiety disorders consistently show lower choline levels in key brain regions that regulate thinking and emotions. This biochemical difference may help explain why the brain reacts more intensely to stress in ...

Researchers studying people with major psychiatric disorders found that drinking up to four cups of coffee a day is associated with longer telomeres. This suggests a potential slowing of biological aging by about five years. However, drinking five or ...

A low-dose mix of zinc, serine, and branched-chain amino acids boosted neural function and social behavior in autism mouse models. The combination restored more typical synaptic protein patterns and reduced excessive amygdala activity. Individual ...

Scientists have captured a never-before-seen, high-resolution look at influenza's stealthy invasion of human cells, revealing that the cells aren't just helpless victims. Using a groundbreaking imaging technique, researchers discovered that our cells ...

Stanford researchers found that gas stoves expose Americans to surprisingly high levels of nitrogen dioxide--often matching or exceeding outdoor pollution. For millions, cooking alone pushes NO2 over long-term safety thresholds. Smaller homes, ...

A unique vaccine rollout in Wales gave researchers an accidental natural experiment that revealed a striking reduction in dementia among seniors who received the shingles vaccine. The protective effect held steady across multiple analyses and was ...
