Researchers have identified hydrogen sulfide as a surprisingly effective tool for treating difficult nail infections. It penetrates nails more efficiently than current drugs and kills pathogens by disrupting their energy systems. The compound also .. ...

FGF19 triggers the brain to burn more energy and activate fat-burning cells, offering a potential new path for obesity treatments. The hormone enhances thermogenesis and reduces inflammation, but only when the sympathetic nervous system is active. .. ...

Scientists uncovered a surprising four-layer structure hidden inside the hippocampal CA1 region, one of the brain's major centers for memory, navigation, and emotion. Using advanced RNA imaging techniques, the team mapped more than 330,000 genetic .. ...

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 ...
