Adults who pictured a socially connected old age went on to see more of family and friends a decade later, a Vienna-led study of 459 people found, with the expectation preceding the behaviour rather than following it.
Across 20,118 adults in all 50 states, childfree prevalence ran from 22% in California to 9.4% in Louisiana, yet no region emerged: the map is scattered, and state policy levers look unlikely to shift it.
A study of nearly 16,000 children finds that sensory over-responsivity tracks tightly with anxiety and autism, not ADHD, and traces to a weakened link between a memory network and the caudate nucleus.
A study of 58,425 adolescents across 21 countries found that unstructured free time, especially unsupervised hours outside the home, was strongly associated with self-reported offending even after accounting for self-control, parenting and morality. Only having delinquent friends showed a stronger overall association.
Two studies published days apart test how well artificial intelligence explains human reading. Language models match the forward glide of our eyes but fail on rereading. A second model, trained to budget its attention like a person, gets much closer.
In Japan’s shrinking cities, decline barely dented life satisfaction — but fully remote work did, buffering residents against a fading local economy. A nationwide study of 5,645 residents reveals what protects well-being when a town empties out.
A protein already linked to Alzheimer’s turns out to hijack mitochondria directly, flipping their energy production into reverse and flooding nerve cells with reactive molecules, according to a new multi-species study.
Removing a glioblastoma from a mouse brain leaves the blood-brain barrier leaky at the surgical rim for two brief spells. A single dose of an approved liposomal chemotherapy, timed into one of them, stopped the tumor coming back.
A Manhattan Institute report totals up the tax revenue from legal sports betting across US states and finds it small, roughly 0.2% of state receipts, often shifted from lotteries, and plausibly outweighed by the public costs of gambling harm.
A new Urban Institute brief finds Black workers concentrated in the jobs AI is least likely to touch, and shows that once education is accounted for, the exposure gap tracks schooling far more than race.
Two economists reanalysed a public dataset of about 4,000 online test-takers and argue the famous confidence-competence pattern is a statistical artefact. Corrected, it flips: the ablest people looked the most overconfident, not the least.
A review of more than 350 studies finds that low-protein diets extend lifespan in flies and rodents and improve metabolic health in people, though the authors say the right amount likely depends on how active you are.
