Bad news for any extreme exercise junkies out there: excessive vigorous exercise could muffle your immune system. At least, that's what a 2023 study analyzing over 4,700 post-exercise fluid molecules from firefighters suggests. This may be problematic for workers with consistently ...

US researchers have found an astonishingly simple brain circuit of just three types of neurons controls chewing motions in mice, and has a surprising impact on their appetite too. "It's surprising that these neurons are so keyed to motor control," says Rockefeller University ...

A new study suggests staying on top of your eye health could offer a simple avenue for reducing your risks of future brain problems. A team of researchers led by Johns Hopkins Bloomberg School of Public Health epidemiologist Jason Smith has found improvements to common vision problems ...

Chronic blood shortages are driving a search for a universal blood system that would allow doctors to save more lives. Researchers may have just brought us a step closer, by creating miniscule silicon coats for donated blood cells to wear. Incredibly, the new nanotechnology allowed ...

Despite decades of research, the direct cause of brain damage in Alzheimer's disease has remained stubbornly elusive. A team led by Emory University in the US may have just discovered why. Much study has focused, now controversially, on abnormal clumps of naturally occurring proteins that ...

As extreme storms, floods, fires, droughts, cold snaps, and heat waves hit us harder and more often than ever, more than half of our planet is predicted to shift into new climate zones by the end of the century. A new interactive map, The Future Urban Climates, allows you to explore how ...

Last year an ant species was caught using antibiotics – now, another has been observed performing amputations. Researchers have just confirmed with experiments that this surgery and the other treatments ants provide each other do indeed save ant lives. While we have known for a few ...

Powerful new imaging techniques reveal humans were already crafting complex hunting weapons from wood 300,000 years ago, upending the stereotype of the Stone Age. Archeologists have previously suspected humans have been using wooden tools for at least as long as stone ones, but due to ...

A recent analysis of a sperm whale's vocalizations suggests variations in 'clicks' represent a kind of alphabet that forms the basis of a complex communication system. Members of the conservation initiative Project CETI discovered series of clicks less than 2 seconds in length act as codas ...

Dim-witted dope or brainy brawn? The debate over T. Rex's smarts continues, with a new paper leaning toward the original theory that these fearsome giants weren't all that bright. In 2023 a controversial study suggested one of the world's most infamous dinosaurs, Tyrannosaurus rex, could ...

Strange as it might seem for a hairless creature, frogs have provided us with some critical clues on the origins of our luscious locks – a defining mammalian feature whose insulative powers helped us spread across the Earth. While the amphibians possess nary a single hair themselves, one ...

Squirming, pink, and worm-like, hatchling caecilians mewl in high-pitched clicks as they wriggle towards their mother's behind. There, they cluster in writhing piles, mouths probing demandingly at her rounded rear end for a sip of milk. Seemingly in response to her offspring's physical and ...
