A 2026 Environmental Science & Technology experiment found that wild guppies still reduced maze solve times with practice after 11-day exposure to environmentally motivated amitriptyline concentrations, but exposed males made 26.35% to 34.21% more navigation errors than control males.1 The result is a sex-specific accuracy signal, not a blanket claim that antidepressant pollution erased learning. …
A 2026 qualitative case study of 8 top-performing HEALing Communities Study communities linked opioid-response implementation success to representative coalition membership, shared goals, data connectivity, and communications campaigns, not to a simple urban-vs.-rural split.1 The useful lesson is operational: coalitions worked when collaboration was turned into service reach for medication for opioid use disorder and overdose …
A 2026 emergency department claims analysis estimated 3.87 million United States ED visits in 2021 where take-home naloxone could have been clinically relevant, compared with 226,453 ED-treated opioid-overdose visits in the same database.1 The finding reframes naloxone distribution as an emergency-care workflow for overdose risk, polysubstance exposure, long-term opioid use, and patients who arrive after …
A Kaiser Permanente Southern California cohort involving 294,937 children linked extreme prenatal nighttime heat to autism diagnosis by age 5, with stronger associations at the 99th percentile than the 90th percentile.1 Compared with nighttime minimum temperature, daytime maximum temperature did not show the same confirmed whole-pregnancy pattern. Research Highlights Nighttime heat carried the main signal: …
A 2026 study of 250 mothers of children with intellectual and developmental disabilities (IDDs) found that family burden was strongly tied to lower social support, lower family quality of life, and lower happiness. In the structural model, the burden-happiness link was explained by perceived support and family quality of life rather than a direct burden-to-happiness …
A 2026 survey of 467 University of Sydney undergraduate psychology students found that participants generated more and more accurate observable cues for alcohol intoxication than for cannabis intoxication.1 When unanswered cue fields were counted, accurate alcohol cues appeared in 63.2% of possible response slots, while accurate cannabis cues appeared in 37.3%. Research Highlights Alcohol cues …
Coffee is widely framed as cognitively friendly, but a 2026 prospective study from Boscaini et al. published in Nature Communications used shotgun metagenomics, metabolomics, and cognitive testing in 62 healthy adults to show that coffee drinkers and non-coffee drinkers differ on the gut microbiome, key neurotransmitter-related metabolites, and behavioral measures — with coffee drinkers showing …
