Scientists at the University of Minnesota have shown that disrupting how oral bacteria communicate can shift dental plaque toward communities associated with better oral health, potentially opening the door to new ways of preventing gum disease without wiping out beneficial microbes.
Researchers have identified 259 genes associated with chronic fatigue syndrome, or myalgic encephalomyelitis, in the largest genetic analysis to date. This finding multiplies the number of implicated genes by six compared to a study just four months earlier. The work suggests potential paths for new treatments by targeting genetic factors.

A comprehensive analysis of over 2,500 studies shows that medical cannabis has strong evidence for only a few specific uses, despite widespread public belief in its broader effectiveness. Led by UCLA Health researchers, the review highlights gaps between perceptions and scientific proof for conditions like chronic pain and anxiety. It also identifies potential risks, particularly for adolescents and daily users.
A statewide analysis led by the University of Colorado Boulder found that about 43% of cannabis flower products sold in Colorado listed THC levels outside the state’s ±15% accuracy threshold—most overstating potency—while 96% of concentrates matched their labels. The results point to a need for tighter testing and clearer packaging to bolster consumer trust.

Researchers in Tübingen have found that people with prediabetes can reduce their risk of developing type 2 diabetes by 71% through lifestyle changes that normalize blood sugar levels, even if they do not lose weight. The study emphasizes the role of improved fat distribution over mere weight reduction. This challenges current guidelines focused primarily on shedding pounds.
