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 Sanger Institute and the University of Cambridge studied... Continue Reading →

The neuroscience of autism: New clues for how condition begins

UNC School of Medicine scientists unveiled how a particular gene helps organize the scaffolding of brain cells called radial progenitors necessary for the orderly formation of the brain. Previous studies have shown that this gene is mutated in some people... Continue Reading →
