7 Brain stress signals predict alcohol relapse risk in abstaining mice

A study found that abstaining mice predisposed to relapse showed more than double the activity in the bed nucleus of the stria terminalis (BNST), a stress-related brain region, even before alcohol access. This elevated neural signal appeared before relapse and could eventually predict relapse vulnerability in humans.

  • Relapse-prone abstinent mice showed 2x+ BNST activity
  • Elevated brain stress signal appeared before alcohol access
  • BNST activity suggests predictive marker for human relapse risk
  • Brain changes during abstinence may increase relapse vulnerability

6 Ketogenic Diet Restores Exercise Benefits for People with High Blood Sugar

A new study found that a high-fat, low-carbohydrate diet can restore exercise's metabolic benefits in individuals with hyperglycemia.

  • Study led by Sarah Lessard at Virginia Tech's Fralin Biomedical Research Institute, published Feb. 25, 2026 in Nature Communications
  • Mice on ketogenic diet normalized blood sugar within one week, reversing hyperglycemic state
  • Ketogenic diet caused muscle remodeling, increasing slow-twitch oxidative fibers and improving aerobic exercise response
  • Finding contrasts with traditional low-fat diet recommendations and suggests diet and exercise work together synergistically for metabolic health
