Scientists have discovered that the Moon-forming collision may have depended heavily on how hot and physically strong early Earth and Theia were. New simulations found that some impacts create the familiar disk of debris that later becomes the Moon, ...

UCLA researchers developed ready-made cancer-fighting T cells from cord blood stem cells that can attack solid tumors through two separate detection systems. In mice, a single dose controlled cancer and extended survival while avoiding a dangerous .. ...

Scientists have directly observed how two negatively charged DNA molecules can pair up despite normally repelling each other. Positively charged metal ions appear to bridge the gap, helping matching DNA helices align groove for groove like a ...

Scientists have used DNA from living descendants to identify four more members of the doomed Franklin expedition, including Harry Peglar, whose identity had remained uncertain for 166 years. The findings offer new clues about the sailors who survived ...

Researchers have created a foam-based material that produces intense whiteness and water repellency without titanium dioxide pigments or PFAS chemicals. Inspired by natural structures in snow, clouds, flowers, and lotus leaves, the material uses tiny ...

While clearing debris to protect ancient Egyptian tombs from flash floods, researchers near Luxor stumbled upon an unknown 3,000-year-old tomb. Its remarkably preserved paintings depict an official named Paser, his wife, religious scenes, and ...

Ancient human remains from Sulawesi suggest people were habitually using the psychoactive betel nut as far back as 25,000 years ago. Researchers found both unusual tooth wear and traces of arecoline, the nut's mind-altering compound, in the teeth of ...

The Mediterranean may seem far removed from the world's major tsunami zones, but history and modern modeling show that destructive waves can strike the French Riviera with surprisingly little warning. Some tsunamis could reach shore in under 10 ...

Researchers have designed a new DNA-based treatment that targets PCSK9, a protein closely tied to high LDL cholesterol and atherosclerosis. Their most effective molecule reduced PCSK9 protein by 87% in human liver cells and lowered cholesterol by 47% ...

People who drank at least one sugar-sweetened beverage a day had roughly 2.45 times the risk of gastric cancer compared with those who rarely consumed them, according to a decades-long study of more than 112,000 U.S. adults. Artificially sweetened .. ...
