Scientists discover the nutrient that can supercharge cellular energy

7:50
Researchers discovered that leucine, a nutrient found in protein-rich foods, can supercharge mitochondria by protecting crucial energy-producing proteins inside cells. The breakthrough uncovers a powerful new link between diet and cellular energy — with possible implications for cancer and metabolic disease treatments.

MIT scientists discover amino acid that helps the gut heal itself

7:18
MIT scientists have identified cysteine — an amino acid found in foods like meat, dairy, beans, and nuts — as a potent trigger for intestinal repair. In mice, a cysteine-rich diet activated immune cells that released healing signals, helping stem cells rebuild damaged intestinal tissue after radiation exposure. Researchers say the discovery could eventually lead to new dietary therapies for cance…

UNESCO warns a tsunami in the Mediterranean is inevitable

5:42
The French Riviera may look like an unlikely place for a tsunami disaster, but scientists warn the threat is far more real than most people realize. Historical events and new modeling show that destructive waves have already struck the Mediterranean coast — and could hit again with very little warning. Some tsunami scenarios could reach beaches in under 10 minutes, leaving almost no time for trad…

Scientists solve 320-million-year mystery of reptile bone armor

5:42
Reptiles have been growing armor in their skin on and off for hundreds of millions of years, but scientists never fully understood how it evolved. A massive new evolutionary study shows these skin bones appeared independently in multiple lizard groups rather than coming from a single armored ancestor. Even more astonishing, Australian goannas lost this armor long ago — then evolved it back again …

New quantum sensor could count individual photons and hunt dark matter

5:42
Researchers have built an ultra-sensitive sensor capable of detecting unimaginably small amounts of energy — below one zeptojoule. The breakthrough relies on fragile superconducting materials that react to even the slightest temperature change. This level of precision could improve quantum computers, enable photon counting, and even help scientists detect elusive dark matter particles from space.

Scientists found a hidden Alzheimer’s trigger and shut it down

15:16
A newly identified enzyme called IDOL could become a major new target in the fight against Alzheimer’s disease. Researchers found that removing it from neurons sharply reduced amyloid plaques and improved key brain processes linked to resilience and communication between cells. The discovery may lead to future treatments that go beyond slowing Alzheimer’s — potentially helping protect the brain f…

Scientists use light to create tiny molecules that could transform medicine

15:16
Researchers have developed a light-driven method for creating tiny, high-energy “housane” molecules that are valuable for drug development and materials science. These compact ring-shaped structures are difficult to produce because of the intense internal strain they contain. By using photocatalysis and carefully tuning the starting molecules, the team managed to guide the reaction into a clean a…

Britain’s 11,000-year-old “oldest northerner” was a 3-year-old girl, DNA reveals

15:16
Scientists have identified the oldest known human remains in Northern Britain as a young girl who lived around 11,000 years ago. Found in a Cumbrian cave and nicknamed the “Ossick Lass,” she was likely between 2.5 and 3.5 years old when she died. Nearby jewelry and evidence of multiple burials suggest the cave held deep spiritual importance for some of Britain’s earliest hunter-gatherers. The dis…

Scientists found a giant magnetic “twist” hidden inside the Milky Way

15:16
Astronomers have uncovered a strange magnetic “flip” hidden inside the Milky Way. Using a new radio telescope, researchers mapped the galaxy’s magnetic field in unprecedented detail and discovered that a mysterious reversal in the Sagittarius Arm cuts diagonally across space. The finding could reshape how scientists understand the structure and future evolution of our galaxy.

Scientists discover massive natural hydrogen source beneath Canada

15:16
Scientists in Canada have discovered that ancient underground rocks are naturally producing hydrogen gas — and lots of it. Measurements from mine boreholes in Ontario show the gas can flow continuously for years, offering a potential new source of clean energy called “white hydrogen.” Researchers say this hidden resource could help power industries and remote communities while cutting carbon emis…

Scientists discover why Alzheimer’s risk hits women so much harder

15:16
Women may be especially sensitive to the effects of common dementia risk factors, according to a new UC San Diego study of over 17,000 adults. Researchers say tailoring prevention strategies specifically for women could be key to reducing Alzheimer’s risk.

Scientists use DNA from poop to save the world’s rarest marsupial

20.května
Scientists in Australia are using cutting-edge DNA techniques to help save one of the world’s rarest marsupials — the critically endangered Gilbert’s potoroo, with fewer than 150 left in the wild. By analyzing tiny traces of DNA in the animals’ scat, researchers uncovered clues about the elusive fungi the potoroos depend on for survival. The findings could help conservationists identify safer new…

T. rex’s tiny arms may have evolved for a surprisingly brutal reason

20.května
Why did T. rex have such tiny arms? Scientists now think it’s because its giant head became the ultimate hunting tool. Across multiple dinosaur groups, stronger skulls and crushing jaws evolved alongside shrinking forelimbs, especially in predators hunting enormous prey. In other words, once the bite became deadly enough, the arms may have stopped mattering.

Scientists discover strange link between vitamin D and pain

20.května
Low vitamin D levels could be quietly making breast cancer surgery recovery far more painful. In a new study, patients deficient in vitamin D were three times more likely to experience moderate to severe pain after mastectomy surgery and ended up using significantly more opioid medication to cope. Researchers say vitamin D may help regulate how the body processes pain through its effects on infla…

Humpback whale breaks migration record with 15,000 kilometer ocean journey

20.května
Scientists have uncovered an astonishing new chapter in humpback whale migration: two whales were found to have traveled between breeding grounds in Australia and Brazil, crossing more than 14,000 kilometers of open ocean. One whale shattered records by covering at least 15,100 kilometers between sightings, marking the longest confirmed journey ever documented for an individual humpback whale.
