Warming could help make the Indian Ocean a stronger climate buffer

The world's oceans help slow climate change by absorbing carbon dioxide (CO₂) from the atmosphere, but how much they take up can vary throughout the year. New research, published in Geophysical Research Letters, suggests these seasonal patterns are changing across the Indian Ocean, potentially affecting how it helps to regulate Earth's climate.

'A uniquely direct route that might cause damage': Scientists uncover link between air pollution and eye diseases like glaucoma

Aging is one of the biggest risk factors for developing glaucoma or cataracts — but as scientists look more closely at what happens to the eyes over a lifetime, they are finding that people's exposure to air pollution also plays a role in whether they develop these eye conditions.Glaucoma, which affects about 80 million people worldwide, is a group of diseases that damage the optic nerve, which carries visual information from the eye to the brain. It can lead to permanent vision loss, usually affecting peripheral vision at first and later central vision. Cataracts are even more common, affecting more than 94 million people globally; the condition occurs when the eye's lens becomes cloudy, ca...

Scientists discover a natural compound that could protect the brain from too much salt

Eating too much salt may do more than raise blood pressure. It could also harm memory and social behavior. In a new study, Japanese researchers discovered that a soy-derived compound called LPC70 helped protect mice from several damaging effects of a high-salt diet. Mice given the supplement had lower blood pressure, better memory, and improved social interactions compared with mice consuming excess salt alone.

Physicists create a bizarre new quantum state called a fractional fermi sea

Physicists have discovered a strange new state of quantum matter in which ultracold atoms defy familiar organizational rules, forming a highly excited yet surprisingly orderly configuration called a "fractional Fermi sea." The discovery challenges established quantum theories and hints at exotic quasiparticles that scientists have dubbed potential "super-Fermions."

Eating blueberries every day may have a surprising effect on your mood

Eating blueberries every day could have surprising effects on mood, according to a small study that found greater reductions in depressive symptoms among older adults who consumed the fruit for three months. Researchers also detected changes in gut microbial enzymes, suggesting a possible gut-brain connection, although the mood benefits were not statistically significant compared with a placebo.

Black Death had dramatic effect on species diversity as humans abandoned farmland, study finds

When millions of people died in Europe during the Black Death, biodiversity suffered too, new research suggests. The findings suggest that human activities once promoted biodiversity in the landscape — and experts say we could use these findings to boost biodiversity in our modern agricultural landscapes. The 14th century was a tumultuous time for the people of Europe. Persistent cold, wet weather at the beginning of the century led to widespread agricultural failures and unprecedented levels of starvation in what became known as the Great Famine from 1315 to 1317. This was followed by the Black Death, an epidemic of bubonic plague caused by the bacterium Yersinia pestis that killed more tha...

Hybrid diamond chip strengthens interactions between light and quantum bits

Researchers have developed and demonstrated a new hybrid photonic platform that integrates quantum emitters with photonic devices, providing a way to reliably control the interaction between photons and quantum information carriers. The chip-based platform, which combines gallium phosphide (GaP) with a diamond substrate, could help make quantum networks more practical by providing a way to connect quantum devices over long distances.

Magic mushroom ingredient takes the fight out of aggressive fish

A psychedelic compound found in magic mushrooms appears to have an unexpected effect: calming highly aggressive fish. Researchers discovered that low doses of psilocybin significantly reduced aggressive attacks in mangrove rivulus fish without disrupting their normal social interactions. The findings suggest psilocybin may selectively calm escalating aggression rather than simply suppressing all behavior.

Scientists uncover 3 key brain pathways linked to lasting depression relief

Researchers have uncovered three brain pathways linked to lasting improvements in people receiving deep brain stimulation for severe, treatment-resistant depression. They also discovered that patients who failed to improve after two years shared a striking pattern: insufficient stimulation of a crucial brain connection. The findings suggest that millimeters in electrode placement could make a major difference in treatment outcomes.

Two monster black holes could collide in just 100 years

Astronomers have uncovered compelling evidence of two supermassive black holes spiraling toward a potentially spectacular collision at the center of galaxy Mrk 501. A previously unseen jet of particles revealed the likely presence of a second black hole, with observations suggesting the pair completes an orbit every 121 days. Depending on their masses, these cosmic giants could merge in as little as 100 years.

Lion droppings yield previously unknown microbial species, exposing hidden diversity inside Africa's big cats

Scientists know a great deal about how lions hunt, breed and survive, but the microscopic communities living inside them have remained largely unexplored. Now, a study of wild lions in Namibia is beginning to change that, while revealing how much biology is still missing from the world's genomic databases.

Scientists discover that male and female skin play by different rules

Scientists have uncovered a surprising difference in how male and female skin repairs and renews itself. By tracking individual skin stem cells in living mice for five months, researchers discovered that female cells work together in a highly coordinated way, while male cells operate more independently. This synchronization, driven by sex hormones, helps explain why wounds heal faster in female mice, especially during the first few days.

This 850-year-old 'firework' supernova is full of mysterious knots

Quick factsWhat it is: Pa 30, a supernova remnantWhere it is: 7,500 light-years away, in the constellation CassiopeiaWhen it was shared: Oct. 6, 2026A mysterious "guest star" recorded by medieval astronomers nearly 850 years ago has revealed new secrets after scientists obtained the clearest images yet of its explosive aftermath. New observations of Pa 30, thought to be the leftovers of a historic supernova called SN 1181, show that its spectacular firework-like filaments are not smooth streams of material. Instead, they consist of chains of tiny gas knots.SN 1181 is so called because astronomers in China and Japan recorded its brief appearance in the year 1181, when they saw it as a naked-e...

Can cuttlefish hypnotize their prey?

Like their cephalopod cousins the octopuses, cuttlefish are masters of disguise. As they hunt, these marine predators send waves of color across their skin. The rainbow display stops prey in their tracks, granting the cuttlefish just enough time to shoot out two specialized hunting tentacles at lightning speed and snatch them into range of their deadly beaks. But can cuttlefish actually mesmerize prey with their colorful skin changes? Or is something fishier at play?Experts told Live Science that cuttlefish are ingenious hunters, but that there's likely an even more mysterious process than hunter to prey hypnosis going down on the seafloor.A calculated hunterCuttlefish are visual hunters, us...
