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 [...]

People who eat a lot of junk food are more likely to die young , warns new research. The more ultra-processed products - such as burgers, sausages and chips - you eat, the more likely you are to die prematurely from a preventable death, say scientists. The new study analyzed nationally representative dietary surveys and mortality data from eight countries - including the UK and United States. It shows that premature deaths attributable to consumption of ultra-processed foods , or UPFs, [...]

Scientists say it is a member of Haidomyrmecinae - an extinct group that only lived during the Cretaceous period. By Stephen Beech 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 [...]

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 [...]

(Felipe Toledo via SWNS) By Talker By Dean Murray via SWNS 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 [...]

Several species have been growing their own food since long before humans evolved.

More than 150,000 people have died every year worldwide due to heat waves since 1990, according to new research. Europe had the highest population-adjusted mortality rate, according to the first global mapping of heat wave-triggered deaths. The global surface temperature has increased by 1.14 degrees Celcius from 2013 to 2022, say scientists, and is expected to rise by another 0.41C to 3.41C by 2081 to 2100. They warned that, with the increasing impacts of climate change, heat waves [...]
