A 113-million-year-old fossilized ant is the oldest ever discovered. The “remarkably well-preserved" hell ant was found in limestone in Brazil. Scientists say it is a member of Haidomyrmecinae - an extinct group that only lived during the Cretaceous period. They had highly specialized, "scythe-like" jaws that they probably used to pin or impale prey, according to a study published in the journal Current Biology. Study author Anderson Lepeco said: “Our team [...]

  THURSDAY, April 10, 2025 (HealthDay News) -- Heavy drinkers have an increased risk of developing brain lesions associated with memory and thinking problems, a new study says. Folks who imbibe eight or more alcoholic drinks a week have an increased risk of hyaline arteriolosclerosis, or a thickening and narrowing of the small arteries that feed the brain, researchers reported April 9 in the journal This condition makes it harder for blood to flow, which can damage the brain over [...]

Drinking eight glasses of wine or pints of beer a week more than doubles the risk of brain damage compared to teetotallers, suggests new research. Boozers who down eight or more alcoholic drinks every week have an increased risk of brain lesions associated with memory and thinking problems, say scientists. They explained that the condition, caused hyaline arteriolosclerosis, causes the small blood vessels to narrow, becoming thick and stiff - making it harder for blood to flow, which can [...]

Rio de Janeiro (AFP) – In Brazil, where about 16 wild animals become roadkill every second, a computer scientist has come up with a futuristic solution to this everyday problem: using AI to alert drivers to their presence. Direct strikes on the vast South American country's extensive road network are the top threat to numerous species, forced to live in ever-closer proximity with humans. According to the Brazilian Center for Road Ecology (CBEE), some 475 million vertebrate [...]

Teenagers glued to their screens for more than three hours a day suffer worse back pain, a new study has revealed.
