Genetic variant prompts cells to store fat, fueling obesity

Obesity is often attributed to a simple equation: People are eating too much and exercising too little. But evidence is growing that at least some of the weight gain that plagues modern humans is predetermined. New research ...

Study in mice identifies type of brain cell involved in stuttering

Researchers believe that stuttering—a potentially lifelong and debilitating speech disorder—stems from problems with the circuits in the brain that control speech, but precisely how and where these problems occur is unknown. ...

Pinpointing how cells regulate long-lasting memories

The brain has a knack for safekeeping our most treasured memories, from a first kiss to a child's birth. In a new study in mouse cells, Columbia neuroscientists have mapped some of the molecular machinery that helps the brain ...

Key to targeting the spread of pancreatic cancer

An international team of researchers has revealed how aggressive pancreatic cancer cells change their environment to enable easy passage to other parts of the body (or metastasis) - the main cause of pancreatic cancer related ...

Low doses of radiation promote cancer-capable cells

Low doses of radiation equivalent to three CT scans, which are considered safe, give cancer-capable cells a competitive advantage over normal cells in healthy tissue, scientists have discovered. Researchers at the Wellcome ...

Glowing brain cells illuminate stroke recovery research

A promising strategy for helping stroke patients recover, transplanting neural progenitor cells to restore lost functions, asks a lot of those cells. They're supposed to know how to integrate into a mature (but damaged) brain. ...
