Microplastics, the tiny plastic particles smaller than five millimeters, have emerged as one of the most pressing environmental and public health concerns of our time. Continuous research shows their presence not only in oceans, soil, and air but increasingly inside the human body. Now, a groundbreaking review reveals microplastics have been detected in human bones. Since plastics take a lot of time to decompose, these microplastics originate either from larger plastic items breaking apart or [...]

Three huge asteroids could hit Earth, and a group of astronomers is sounding the alarm. They could cause destruction on a scale never seen before. These asteroids are almost invisible because of the sun's glare. Scientists say that three asteroids are orbiting Venus and could hit Earth in a matter of weeks because their paths are unstable. The three city-killer asteroids that Venus is hiding could cause catastrophic damage before we can respond, as per a report by The NY Post. The [...]

Asteroids carrying energy over a million times more powerful than the Hiroshima bomb could be on a potential collision course with Earth, warn scientists from Brazil, France, and Italy. According to a new study published in Astronomy and Astrophysics, three massive asteroids—identified as 2020 SB, 524522, and 2020 CL1—have been hiding in a blind spot behind Venus, shielded from Earth-based telescopes by the Sun's intense glare. These so-called “Venus co-orbitals” [...]

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 [...]

THURSDAY, Nov. 21, 2024 (HealthDay News) -- 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 [...]

More than 1.53 lakh deaths a year were associated with heatwaves around the world, with over a fifth of these deaths - the greatest share - coming from India, according to new research looking at data over 30 years since 1990. India was followed by China and Russia, with each experiencing roughly 14 per cent and 8 per cent of these heatwave-linked excess deaths, respectively. The study, led by Monash University, Australia, found that heatwave-linked excess deaths accounted for about a third [...]

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 animals die on the road every year [...]
