A blood cancer uses a secret weapon for tearing bone apart. That same mechanism may allow breast cancer and other types of tumors to spread to bones, a new study suggests.
In patients with the blood cancer multiple myeloma, an enzyme called thymidine phosphorylase sets off a chain reaction that leads to bone...
Earth might have a kindred planet orbiting the star next door. A world at least 1.3 times as massive as Earth appears to orbit the closest star to the sun: Proxima Centauri, a dim red orb about 4.2 light-years away.
Dubbed Proxima b, the planet is cozied up to its star, needing just 11.2 days to complete one orbit. But despite the proximity to...
Climate change flaunted its deadly side during the 2003 European heat wave, which killed over 70,000 people across the continent. In London and Paris alone, global warming led to 570 more heat-related deaths than would be expected without human-caused warming, researchers estimate in the July Environmental Research Letters.
Daniel Mitchell of the University of Oxford and...

After decades of research revealing their sophisticated lives, Neandertals still can’t shake their reputation as knuckle-dragging cavemen. And it’s the Old...
COLUMBIA, Mo. — If you find a daddy longlegs in your house, don’t be scared. “Daddy longlegs are actually pretty docile animals when it comes to interacting with humans,” says evolutionary biologist Kasey Fowler-Finn, who studies the arachnids at St. Louis University. Specifically, she studies daddy longlegs sex. She is using this common group of arachnids (they’re not spiders) to explore...
Scientists usually shy away from using the word miracle — unless they’re talking about the gene-editing tool called CRISPR/Cas9. “You can do anything with CRISPR,” some say. Others just call it amazing.
CRISPR can quickly and efficiently manipulate virtually any gene in any plant or animal. In the four years since CRISPR has been around, researchers have used it to fix genetic...
Brain scientists Eric Jonas and Konrad Kording had grown skeptical. They weren’t convinced that the sophisticated, big data experiments of neuroscience were actually accomplishing anything. So they devised a devilish experiment.
Instead of studying the brain of a person, or a mouse, or even a lowly worm, the two used advanced neuroscience methods to scrutinize the inner workings of...

Sex matters when it comes to cornea transplants — at least for women.
Corneas are low on the list of organs that cause rejection, but it happens more often when women receive corneas from men, researchers report online July 22 in the American Journal of Transplantation. In data from nearly 17,000...
Forget garlic. In real life, a tomato can defeat a vampire. And researchers have now figured out the first step to vegetable triumph.
The vampires are slim, tangling vines that look like splats of orange or yellow-green spaghetti after a toddler’s dinnertime tantrum. Botanically, the 200 or so Cuscuta species are morning glories gone bad. In the same family as the heavenly blue...
When someone uses the phrase “sleeping like a baby,” it’s obvious that they don’t really know how babies sleep. Many babies, especially newborns, are lousy sleepers, waking up every few hours to rustle around, cry and eat. For creatures who sleep up to 18 hours per 24-hour period, newborns are exhausting.
That means that bone-tired parents are often desperate to get their babies to...
