Do repeated football head hits disrupt the gut microbiome?2:11 A small exploratory study of collegiate football players found that non-concussive head impacts are correlationally linked to acute and season-long shifts in gut microbiome composition, with changes most pronounced 48–72 hours after significant impacts. However, most associations weakened after correction for multiple testing, and the authors stress the findings are preliminary and hypothesis-gen… What drives adult ADHD symptoms? Study points to executive function over environment1:39 Adults diagnosed with ADHD later in life had fewer childhood symptoms than those diagnosed in childhood, but both groups showed similar symptom severity in adulthood.

Liver fat may disrupt post-meal glucagon control in early type 2 diabetes1:39 Researchers found that MASLD, rather than type 2 diabetes alone, was linked to higher fasting glucagon levels in adults with newly diagnosed diabetes and matched controls. In people with early type 2 diabetes, higher liver fat was specifically associated with exaggerated early post-meal glucagon responses, independent of insulin sensitivity, visceral fat, amino acids, or NEFAs. Autistic people gain measurable police-interaction skills after short VR training0:35 A randomized controlled trial found that Floreo’s virtual reality Police Safety Module helped autistic teens and adults reduce fidgeting during live police-interaction assessments compared with video-based BeSAFE training. Both groups reported greater knowledge and comfort after training, but the clearest behavioral gains were seen in the VR group, supporting immersive practice as a promising too… Can meditation backfire? Study finds brief mindfulness may heighten stereotype bias0:34 Mindful meditation may not only fail to reduce cognitive bias but, based on the study findings, may exacerbate stereotypes. Lab-grown diamonds enable highly-sensitive radiation dose measurements19:03 A team led by researchers from Tokyo Metropolitan University, in collaboration with Tohoku University and Orbray Co., Ltd., using heteroepitaxial diamond materials developed by Orbray, have shown that lab-grown diamonds might realize a radiation dosimeter compatible with both medical diagnosis and radiation therapy. NIH funding terminations disproportionately affect marginalized health equity researchers9.května Researchers from University of California San Diego Herbert Wertheim School of Public Health and Human Longevity Science have found that recent federal grant terminations targeting research on health equity and gender identity have disproportionately affected scientists from the very communities those studies aim to support. Online friendships with strangers linked to greater adult loneliness9.května A first-of-its-kind study of U.S. adults suggests that all of those strangers you're friends with on social media are not helping you to feel less lonely. Sexual arousal can blur recognition of unclear rejection signals9.května Sexual arousal can lead to "tunnel vision" that makes it more difficult to recognize when someone is just not that into you, according to new research in Personality and Social Psychology Bulletin. Informal networks and professional culture shape advancement in UK surgical careers9.května While entry into medicine and surgery has become more diverse, why does that diversity disappear at senior levels? A new study from the University of Surrey argues that the answer lies in how careers are judged day-to-day. |
