Scientists at Michigan State University have uncovered the molecular "switch" that powers sperm for their final, high-speed dash toward an egg. By tracking how sperm use glucose as fuel, the team discovered how dormant cells suddenly flip into ...

Neuromorphic computers modeled after the human brain can now solve the complex equations behind physics simulations -- something once thought possible only with energy-hungry supercomputers. The breakthrough could lead to powerful, low-energy ...

A new study shows that dogs and cats may be helping an invasive flatworm spread. Researchers analyzing over a decade of reports discovered the worm attached to pet fur. Its sticky mucus and ability to reproduce alone make it highly adaptable. Pets .. ...

Couples who intentionally slow down and soak in their happy moments together may be building a powerful shield for their relationship. Researchers at the University of Illinois found that partners who regularly savor shared experiences--whether ...

Scientists are launching an ambitious global effort to map the "human exposome" -- the lifelong mix of environmental and chemical exposures that drive most diseases. Backed by new partnerships with governments, UNESCO, and international science ...

A global study has uncovered a mysterious group of gut bacteria that shows up again and again in healthy people. Known as CAG-170, these microbes were found at lower levels in people with a range of chronic diseases. Genetic clues suggest they help . ...

Astronomers have uncovered a distant planetary system that flips a long-standing rule of planet formation on its head. Around the small red dwarf star LHS 1903, scientists expected to find rocky planets close in and gas giants farther out -- the same ...

A massive star 2.5 million light-years away simply vanished -- and astronomers now know why. Instead of exploding in a supernova, it quietly collapsed into a black hole, shedding its outer layers in a slow-motion cosmic fade-out. The leftover debris ...

A new study suggests that generosity may be more than a moral lesson--it could be shaped by how different parts of the brain work together. By gently stimulating two brain regions and syncing their activity, researchers found that people became more ...

Fish oil's cancer-fighting reputation may hinge on a little-known gene. Researchers discovered that omega-3s like EPA and DHA help curb colorectal cancer only when the enzyme ALOX15 is present. Without it, fish oil sometimes increased tumor growth in ...
