Key Takeaways Parents can influence the physical activity levels of their children Kids are more likely to become couch potatoes if Mom or Dad don’t move much Likewise, children are more likely to be active if their parents exercise WEDNESDAY, Sept. 10, 2025 (HealthDay News) — Kids are more likely to become couch potatoes — or enthusiastically active — based on what they see their parents doing day-to-day, a new study says. The example [...]

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 [...]

Heavy drinkers have a higher risk of brain lesions associated with dementia Eight or more drinks a week increase risk of brain lesions caused by thickened arteries Heavy drinking also was associated with more tau tangles, a hallmark of advanced Alzheimer’s disease 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 [...]

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 [...]

Weight training helps protect older people from dementia , according to new research. Volunteers with mild cognitive impairment who practiced strength training showed improvements in memory and brain anatomy after six months, say scientists. Weight training has been previously shown to improve strength and muscle mass, reduce body fat, and contribute to well-being and mental health. Now, a new study conducted at the State University of Campinas (UNICAMP) in Brazil suggests it protects [...]

Having achy, painful joints isn't just a physical woe: Coupled with depression, it could also degrade an older person's brain function over time. That's the conclusion of a study of almost 5,000 older Britons tracked for 12 years. People who had both chronic joint pain and depression tended to perform worse on cognitive tests, especially tests focused on memory skills. “Both pain and symptoms of depression act on areas of the brain [mainly the hippocampus] associated [...]

The world’s second-smallest vertebrate has been discovered - a tiny toad living in a Brazilian rainforest. Researchers say the flea toad measures just 6.95 millimeters in length and can fit on the tip of a finger. The name of the new species, B. dacnis, pays tribute to Project Dacnis, a conservation, research and education NGO that maintains private areas of the Atlantic Rainforest, including the one where the animal was found, in Ubatuba, on the coast of São Paulo [...]

Key Takeaways Microplastics have been found in numerous human organs, and a new autopsy study finds the brain might now be included on that list 8 of 15 autopsies showed evidence of microplastics in the brain's olfactory bulb The particles might be breathed in, since they are ubiquitous components of air, especially indoors Researchers in Germany and Brazil say that 8 out of 15 autopsied adults had microplastics detected within their brain's smell [...]
