Addiction Starts with an Overcorrection in the Brain
July 1, 2024 4:48 pm | News | CommentsThe National Institutes of Health has turned to neuroscientists at the nation’s most “Stone Cold Sober” university for help finding ways to treat drug and alcohol addiction. Brigham Young University professor Scott Steffensen and his collaborators have published three new scientific papers that detail the brain mechanisms involved with addictive substances.
Stem Cells Halt MS for Two Years
July 1, 2024 12:07 pm | by Cynthia Fox | Articles | CommentsAt 21, MS had Jennifer Molson “wheelchair bound.” But since her stem cell transplant, she has worked, driven, danced at her own wedding. The story had a room of 1,000 professional stem cell scientists sniffling loudly at the International Society for Stem Cell Research (ISSCR) meeting—said sniffling reaching a crescendo when the quiet, pretty Molson concluded: “I’m living proof stem cells can save lives.”
