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 overdrive, burning energy in a carefully controlled, multi-step process. A key enzyme, aldolase, helps convert sugar into the burst of power needed for fertilization, while other enzymes act like traffic controllers directing the flow of fuel.
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 supercomputers while revealing new secrets about how our brains process information.
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 could be giving this slow-moving invader a major boost.
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 reminiscing about a favorite memory, enjoying a dinner together, or looking forward to something exciting—report greater relationship satisfaction, less conflict, and stronger confidence in their future.
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 advisory bodies, the initiative is rapidly expanding across continents. Powered by AI and advanced data tools, the movement seeks to shift medicine beyond genetics and toward the real-world factors shaping human health.
