A rare cancer-fighting plant compound has been decoded

4:15
Scientists at UBC Okanagan have uncovered how plants produce mitraphylline, a rare natural compound with promising anti cancer potential. The team identified two enzymes that work together to build the molecule’s unusual twisted structure, solving a mystery that had puzzled researchers for years. Because mitraphylline appears only in tiny amounts in tropical plants like kratom and cat’s claw, the…

Scientists discover a weak spot shared by polio and common cold viruses

4:15
Scientists at the University of Maryland, Baltimore County, have uncovered a crucial trick used by enteroviruses—the group behind diseases like polio, myocarditis, encephalitis, and even the common cold—to reproduce inside human cells. The team captured, in unprecedented detail, how viral RNA recruits both viral and human proteins to assemble the machinery needed for replication, acting almost li…

Scientists make old blood stem cells young again in major anti-aging breakthrough

4:15
As blood stem cells age, their lysosomes become overactive and damaged, triggering inflammation and weakening the body’s ability to regenerate healthy blood and immune cells. By calming this cellular “overdrive,” researchers restored the stem cells’ youthful function, dramatically boosting their ability to regenerate and produce balanced blood cells.

New drugs could wipe out the “zombie cells” linked to cancer and aging

4:15
Researchers found a new way to kill harmful “zombie” cells that linger after chemotherapy and help cancers become more aggressive. These senescent cells survive by relying on a protective protein called GPX4, even while sitting on the edge of a deadly iron-triggered collapse. New drugs remove that protection, causing the cells to self-destruct. In mice, the approach reduced tumor size and boosted…

Scientists say this algae could remove microplastics from drinking water

14:53
Researchers created a special kind of algae that can grab microscopic plastic pollution out of water almost like a magnet. The algae produce limonene, an orange-scented oil that helps them bind to water-repelling microplastics, forming easy-to-remove clumps. As a bonus, the algae also clean wastewater while growing.

This strange giant dinosaur may change what we know about Jurassic titans

14:53
A bizarre new giant dinosaur discovered in Argentina is giving paleontologists a fresh look at how Jurassic titans evolved in the Southern Hemisphere. Bicharracosaurus dionidei stretched about 20 meters long and carried a strange mix of features seen in both Diplodocus and Brachiosaurus relatives. Scientists believe it could represent the first known Jurassic brachiosaurid from South America, hel…

Scientists reversed biological age in older adults with a 4-week diet change

14:53
A four-week diet change was enough to make some older adults appear biologically younger in a new University of Sydney study. Participants who reduced fat intake or shifted toward more plant-based protein showed improvements in key health biomarkers tied to aging. The strongest results came from a lower-fat, higher-carb diet, while people eating closer to their usual diets saw almost no change.

Scientists discover hidden fat-burning switch that could strengthen bones

14:53
Scientists at McGill University have uncovered a hidden molecular “switch” that turns on a powerful calorie-burning system in brown fat — the body’s heat-generating fat linked to metabolism and weight control. The breakthrough centers on glycerol, a molecule released when fat is broken down in the cold, which activates an enzyme called TNAP and triggers an alternative heat-producing pathway that …

Stunning fossil discovery challenges the origins of animal life

12.května
Scientists revisiting mysterious 540-million-year-old microfossils from Brazil have overturned a major idea about early animal life. What were once thought to be trails left behind by tiny worm-like creatures are now believed to be fossilized communities of bacteria and algae — some with remarkably preserved cells and organic material still intact.

NASA’s Hubble reveals a giant chaotic planet nursery unlike anything seen before

12.května
Hubble has revealed a giant planet-forming disk unlike anything astronomers have seen before. Nicknamed “Dracula’s Chivito,” the enormous structure appears turbulent and oddly lopsided, with towering filaments visible on only one side. The disk contains enough material to potentially create multiple giant planets, making it a fascinating new laboratory for studying how planetary systems are born.

Scientists discover hidden chemical signature that could reveal alien life

12.května
Scientists may have found a powerful new way to hunt for alien life — not by searching for specific molecules, but by looking for hidden patterns in how those molecules are organized. Researchers discovered that living systems leave behind a kind of chemical “fingerprint” in the statistical distribution of amino acids and fatty acids, one that consistently differs from nonliving chemistry.

James Webb telescope reveals the clearest map ever of the Universe’s cosmic web

12.května
Astronomers using NASA’s James Webb Space Telescope have created the clearest map yet of the universe’s “cosmic web” — the enormous hidden structure that connects galaxies across space. By analyzing more than 164,000 galaxies through the massive COSMOS-Web survey, researchers were able to trace this vast network back to when the universe was just a billion years old.

This simple strength test could predict how long you live

12.května
Staying strong may be one of the biggest secrets to living longer — especially for older women. A major study of more than 5,000 women found that simple signs of muscle strength, like a firm hand grip or the ability to quickly stand up from a chair, were strongly linked to lower risk of death over the next eight years.

JUPITER supercomputer breaks world record with 50-qubit quantum simulation

12.května
Scientists in Germany have pulled off a staggering computing feat by fully simulating a 50-qubit quantum computer for the first time ever using Europe’s new exascale supercomputer, JUPITER. The breakthrough shatters the previous 48-qubit record and highlights just how powerful next-generation supercomputers have become.

A supervolcano nearly wiped out humanity 74,000 years ago, but humans did something incredible

12.května
The Toba supereruption 74,000 years ago was so massive it may have plunged Earth into years of darkness and cold, leading some scientists to believe humanity nearly went extinct. Yet archaeological evidence from Africa and Asia suggests early humans were far more resilient than once thought. Instead of disappearing, some communities adapted with new tools, new survival strategies, and remarkable …
