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.

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 fer…

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 co…

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 …

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.

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 digest food and support the broader gut ecosystem. Researchers say the discovery could reshape how we measure and maintain gut health.

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 pattern seen in our own Solar System and hundreds of others. And at first, that’s exactly what they saw. But new observations revealed a surprise: th…

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 continues to glow in infrared light, offering a long-lasting signal of the black hole’s birth. The finding reshapes our understanding of how some of t…

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 willing to share money with others, even when it meant earning less themselves.

Scientists at Cedars-Sinai have uncovered a surprising repair system in the spinal cord that could open new doors for treating paralysis, stroke, and diseases like multiple sclerosis. They found that special support cells called astrocytes—located far from the actual injury—spring into action after damage. These “lesion-remote astrocytes” send out a protein signal, CCN1, that reprograms immune ce…

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 mice—especially DHA. The results suggest that not all supplements work the same way, and genetics could determine who truly benefits.

A dazzling new Hubble image peels back the layers of the mysterious Egg Nebula, a rare and fleeting phase in a Sun-like star’s death just 1,000 light-years away. Hidden inside a dense cocoon of dust, the dying star blasts twin beams of light through a polar opening, carving glowing lobes and delicate ripples into the surrounding cloud. These striking, symmetrical arcs hint that unseen companion s…

As data keeps exploding worldwide, scientists are racing to pack more information into smaller and smaller spaces — and a team at the University of Stuttgart may have just unlocked a powerful new trick. By slightly twisting ultra-thin layers of a magnetic material called chromium iodide, researchers created an entirely new magnetic state that hosts tiny, stable structures known as skyrmions — som…

A remarkable Roman mosaic found in Rutland turns out to tell a forgotten version of the Trojan War. Rather than Homer’s famous epic, it reflects a lost Greek tragedy by Aeschylus, featuring vivid scenes of Achilles and Hector. Its artistic patterns echo designs from across the ancient Mediterranean, some dating back 800 years before the mosaic was made. The discovery suggests Roman Britain was de…

A low-fat vegan diet—without cutting calories or carbs—may help people with type 1 diabetes significantly reduce how much insulin they need, and how much they spend on it. In a new analysis published in BMC Nutrition, participants following the plant-based plan lowered their daily insulin use by 28%, while those on a portion-controlled diet saw no meaningful change.
