A new study published in AJPM Focus found that the risk of child firearm injuries was 45 percent higher during the 2-6 pm afterschool period on school days, compared to non-school days, among students at public schools in New York City. This risk nearly tripled in the immediate period at the end of the school day, typically about 2 pm. A second study, published in Prevention Science, examined the benefits of summer youth employment programs and found that these programs not only reduce youth involvement in crime and violence, but also improve youth educational outcomes, social connections, and community engagement.
The Ngogo chimpanzees of Uganda’s Kibale National Park have long been known for violent clashes with neighboring groups, often resulting in deaths — a phenomenon sometimes described as “chimpanzee warfare.”
Now, a new study led by UCLA anthropologist Brian Wood, in collaboration with John Mitani of the University of Michigan, provides the clearest evidence yet that territorial expansion after lethal conflict can directly boost reproductive success. Following a series of coordinated attacks that claimed at least 21 lives, the Ngogo group’s territory grew by 22%. In the years that followed, females gave birth more often, and their infants were far more likely to survive.
New research from Dartmouth reveals that artificial intelligence can now corrupt public opinion surveys at scale—passing every quality check, mimicking real humans, and manipulating results without leaving a trace. The findings, published in the Proceedings of the National Academy of Sciences, show just how vulnerable polling has become.
