Black holes keep tearing these stars apart, but they survive

Astronomers have found stars that repeatedly skim past supermassive black holes, surviving each encounter while producing a new burst of light. In some systems, those flares mysteriously fade with every return. Researchers now think the key may be stars that were already spinning extremely fast before being captured. That rapid rotation could explain both the fading flares and how the stars ended up in such extraordinarily tight black hole orbits.

This shark can live 400 years. Its eyes barely seem to age

Greenland sharks may live for 400 years without suffering the kind of retinal decline normally associated with aging. Researchers found healthy eye tissue and active proteins specially adapted for seeing blue light in the dim Arctic depths. DNA repair mechanisms may help keep their eyes functioning across centuries. The discovery could eventually offer new clues for protecting human vision as we age.

Quitting alcohol may prime the brain for relapse

Mice that developed compulsive drinking after alcohol abstinence showed more than double the activity in a brain region associated with stress and addiction. Because the signal appeared before they drank again, researchers think it could eventually help predict who is most at risk of relapse.

Peppermint oil lowers blood pressure in just 20 days

Peppermint oil may have an unexpected benefit for people with mildly high blood pressure. Adults who took a small dose twice daily for 20 days saw their systolic blood pressure fall by an average of 8.5 mmHg, while a placebo group showed little change. Researchers say the inexpensive oil could eventually provide a simple additional option for managing elevated blood pressure.

Exercise may work better for keeping weight off than losing it

Exercise may not be a powerful weight-loss tool on its own, but it appears to play a much bigger role in preventing lost weight from returning. By preserving muscle, supporting metabolism, improving fat burning, and regulating appetite and blood sugar, regular activity can make long-term weight maintenance easier.

Multilingual people may have brains up to 13 years younger

People who speak several languages may have brains that age more slowly, with four-language speakers showing brains that appeared about 13 years younger than those of monolinguals. Starting earlier and becoming highly fluent were also linked to a stronger effect.

This frozen fiber makes light and sound interact 1,000x more strongly

Freezing the liquid core of an optical fiber produced an extreme environment where light and sound interact more than 1,000 times more strongly than in ordinary fibers. Researchers used the effect to create optoacoustic memory, potentially paving the way for lower-energy photonic computers and advanced quantum technologies.

JWST finds early galaxies may be 4 times more massive than thought

Astronomers using JWST have discovered that massive early galaxies contain far more small, faint stars than expected. That hidden population could make some of these galaxies three to four times more massive than previous estimates. The finding makes it even harder to explain how enormous, mature galaxies formed so soon after the Big Bang. It could also suggest that planets around low-mass stars were more common in the early universe than scientists realized.

This yeast supplement may boost cancer-fighting immunity

A simple yeast-based food supplement may help restore the immune system’s ability to fight cancer, according to new research in mice. Scientists found that yeast beta-glucan reprogrammed early immune cells in the bone marrow, leading to stronger, longer-lasting cancer-fighting responses against colorectal, skin, and breast cancer cells.

Tooth count may predict survival after pancreatic cancer surgery

Pancreatic cancer patients with at least 21 natural teeth survived nearly two years longer after surgery than those with fewer teeth in a study of 339 people. Researchers suspect tooth loss may reflect decades of inflammation, frailty, nutrition, and other factors tied to the body’s overall resilience.

Archaeologists discover mysterious 400-year-old Indigenous pot in Florida

Found at a historic Potano-Timucua village in Florida, the mysterious vessel is helping reveal a complex world of Native traditions, Spanish influence, trade, and migration.

This gut microbe may help keep you strong as you age

Scientists have linked a specific gut bacterium, Roseburia inulinivorans, to stronger muscles in both humans and mice. Older adults who carried it had 29% greater handgrip strength, while treated mice gained about 30% more grip strength and developed larger, more fast-twitch muscle fibers. The bacterium was also less common in older people. Researchers say it could eventually become a probiotic candidate for helping combat age-related muscle loss.

3 minutes of sprinting does something 90 minutes of exercise does not

A few minutes of sprinting may reshape the bloodstream far more dramatically than a much longer moderate workout. Six 30-second sprints altered nearly a quarter of the blood proteins measured and more than 200 metabolites, while 90 minutes of moderate cycling produced far smaller immediate changes. Many of the proteins affected by sprinting were also associated with lower risks of obesity, type 2 diabetes, and other metabolic diseases.

Scientists catch a hidden electronic state forming in just 30 femtoseconds

Scientists watched a light-triggered hidden state form inside a material in only 30 femtoseconds, revealing a step that had never been seen before. The material first entered a fleeting electronic state in which its bonds reorganized in a repeating pattern, followed by tiny atomic shifts. This ultrafast pathway could offer a new way to control electronic properties with light and help inspire faster, more responsive technologies.
