A buildup of a structural protein called F-actin inside aging brain cells appears to cripple the cellular waste-clearing machinery that keeps neurons healthy, according to a study in Drosophila fruit ...

A study on worms led by researchers from Vanderbilt University School of Medicine in the US has uncovered a previously unknown adaptation to aging that actively remodels one of the largest and most ...

Improvements in public health have allowed humankind to survive to older ages than ever before, but, for many people, these added golden years are not spent in good health. Aging is a natural part of ...

A new discovery from an international collaborative research team has solved the mystery of how cells turn on their recycling process and create "garbage bags" to remove proteins. The process of how ...

Deep in our cells, a wide range of processes are occurring constantly. These cellular processes rely on enzymes to act as catalysts and set off a series of molecular interactions. There are still many ...

Researchers at Clemson University and the Medical University of South Carolina report that their latest study sheds new light on how the body handles cholesterol at the cellular level. According to ...

A molecular geneticist at Montana State University has discovered a cellular process once believed impossible by scientists – the creation of the amino acid cysteine within a living cell when the cell ...
