Key Takeaways Daily orange juice changed activity in 1,700+ genes Gene responses differed between normal weight and overweight individuals Experts say results are promising but are based on a small study without a control drink WEDNESDAY, Nov. 19, 2025 (HealthDay News) — Your morning orange juice may be influencing your health in ways you can't see. In a new study published recently in the journal Molecular Nutrition & Food Research , [...]

Average tree size across the world’s largest tropical rainforest has increased by 3.2% every decade for the last 30 years – consistent with a response to rising carbon dioxide levels, say scientists. The international team of researchers said their findings show the “remarkable resilience” of the forest. The team of almost 100 scientists monitored the size of trees in 188 permanent plots and discovered that the increase has continued for at least 30 years. The [...]

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 set by moms and dads appears to contribute to sedentary or active behavior in their children, researchers report in the journal Sports Medicine and Health Science. “Parents’ level of physical activity can directly influence their children’s [...]

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 Neurology 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 [...]

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 [...]
