A new 3D printing technique can produce exceptionally hard tungsten carbide cobalt while using less of its expensive raw materials. By softening rather than fully melting the material, researchers created defect-free samples with industrial-grade ...

Chemotherapy-surviving ovarian cancer cells may release fructose to help neighboring tumor cells loosen, escape, and spread. The discovery suggests that sugary diets and cholesterol-lowering drugs could influence cancer progression, though the ...

Weight loss is not simply a test of willpower. The human brain evolved to protect body fat during times of scarcity, and it can treat a previously higher weight as the new normal, triggering stronger hunger, cravings, and lower energy use after ...

Scientists have named a newly discovered beetle genus Luffy, inspired by the stretchy hero of the manga and anime One Piece. The insects have unusually long, slender mandibles, antennae, and mouthparts that resemble Luffy's rubber-like ability to ...

Taiwan's steep, remote mountains have sheltered extraordinary forests containing hundreds of giant Taiwania firs. After years of difficult expeditions, LiDAR mapping, and citizen-science detective work, researchers discovered an 84.1-meter (276-foot) ...

Low arginine levels may allow cancer cells and viruses to slip past the immune system by reducing production of a crucial cellular warning protein. In mice, arginine-rich diets led to fewer colon tumors and milder viral infections, suggesting a ...

Thawing Arctic permafrost is releasing ancient carbon into the ocean, raising fears that microbes could turn it into greenhouse gases and accelerate climate change. But sediment cores collected near Canada's Herschel Island reveal a more reassuring . ...

Hidden moon ice may reveal itself through the way it bends and reflects vibrations from moonquakes. The technique could help astronauts locate vital water supplies and uncover clues about the origins of Earth's oceans.

When atomic nuclei smash together at nearly the speed of light, they create the hottest fluid in the universe, but scientists may have overlooked one of its most important forces. New simulations reveal that extreme acceleration builds up along the . ...

Scientists have identified a molecular switch that may help explain why aging makes the brain more vulnerable to diseases such as ALS and Huntington's. In worms, the protein EPS8 builds up with age and triggers signaling that encourages toxic ...
