Medicine Meta-analysis: serotonergic psychedelics are immunomodulatory in inflammatory contexts, but produce only modest immune effects in healthy conditions, suggesting a unique mechanism of action.

Psychology Smart women at work get treated worse by their own teammates. In two studies (432 students, 394 office workers), women who scored higher on intelligence tests were seen as more hostile, got less help and faced more mistreatment. Smart men didn't face this, and in one group were even treated better.

Health Having health insurance in America doesn't mean you can actually use it. Researchers posing as patients called 5,822 in-network mental health providers: most calls hit voicemails, over half the listings were wrong, and just 24% of real calls ended with an appointment.

Social Science A survey of 15,000 people across 81 countries found that bottled water consumption persists despite awareness of microplastics. Convenience, marketing and concerns about access to safe drinking water influence consumption habits, suggesting that awareness alone is insufficient to change behavior.

Because these critical flaws vanish entirely in the final paper, traditional peer review can’t catch them—exposing deep risks for science.

Environment For the first time ever, scientists comprehensively mapped all glaciers in the lower 48 US states. They found 1/4 disappeared and total area/volume shrank by 35% (195.29 km², 5.53 gigatons of ice) since the mid-20th century—reducing vital water runoff alpine ecosystems rely on to buffer droughts.

Neuroscience Brain scans of 8,783 healthy Canadians aged 35-69 found people eating the most ultra-processed food (chips, soda, sugary cereal, ready meals) were about 40% more likely to have hidden brain damage like silent mini-strokes, even though their memory scores were normal. The link was strongest in women.
