Asus launched the ROG Phone 9 and the ROG Phone 9 Pro in 2024, and has since decided to stop releasing new phones. So there has been no ROG Phone 10, and there probably never will be. However, thanks to some leaked firmware, we now know what we could have expected had the ROG Phone 10 and ROG Phone 10 Pro actually launched. Unsurprisingly, both would have been powered by...

Scientists have created a programmable optical chip that can slow light on demand, giving engineers far greater control over how optical signals propagate through a circuit. The technology could provide the delays, synchronization, and buffering functions needed to make light-based computing more practical. A single chip could eventually perform several tasks that currently require separate devices, potentially reducing energy use, cost, and complexity in AI servers and data centers. Read more ›

For most adults, a daily caffeine habit may be safer for the heart than many people assume. A new American Heart Association review found that up to 400 milligrams of caffeine a day, roughly three to five cups of regular black coffee, is generally safe and may even be linked to lower risks of heart disease, stroke, heart failure, and Type 2 diabetes. But the source matters: highly concentrated energy... Read more ›

Going to the cinema, visiting museums, or attending concerts may do more than entertain. Researchers found that older adults who regularly participated in cultural activities tended to have bodies that functioned like those of people about three years younger. They believe stronger social ties, better mental health, and healthier habits could help explain the link, although more research is needed to determine whether cultural activities directly slow aging.

Four nearby white dwarf stars have been discovered hiding in plain sight beside brighter red dwarf companions. Hubble's ultraviolet observations finally revealed the long-hidden stellar remnants, including one just 25 light-years away that took nearly three decades to confirm. The findings match long-standing predictions and suggest our corner of the galaxy may contain many more undiscovered white dwarf binaries. Read more ›

Humans are often described as the planet's ultimate "super-predator," but wild animals do not fear every human the same way. After analyzing three decades of research, scientists found that animals become much more alert and spend less time feeding when people pose a real threat, such as hunters or fishers. In contrast, tourists, researchers, and other non-lethal humans trigger far weaker and less predictable reactions. Read more ›

A 1,600-year-old mummy discovered in Egypt has revealed something archaeologists had never seen before: a fragment of Homer’s Iliad used during embalming. The papyrus was identified as part of the famous "Catalogue of Ships," one of the best-known sections of the ancient epic. Researchers say it is the first archaeological evidence of a Greek literary text being intentionally incorporated into the mummification process, adding a fascinating new chapter to the...

NASA's PACE satellite captured the Black Sea glowing turquoise during its annual phytoplankton bloom. The vivid color comes from massive numbers of coccolithophores, microscopic organisms whose reflective shells brighten the water enough to be seen from space. An astronaut aboard the International Space Station also photographed the bloom spreading through the Bosphorus, revealing swirling currents. Read more ›

Researchers have discovered that a microscopic skeleton inside neurons does much more than hold cells together. It acts as a gatekeeper that controls what brain cells absorb and when they absorb it. When this protective structure weakens, neurons rapidly take in harmful proteins associated with Alzheimer's disease, suggesting that stabilizing it could become a promising new strategy for preventing brain cell damage.

An existing constipation drug may have an unexpected new use: helping clear the "brain fog" that often lingers after depression. In a small clinical trial, people with a history of depression who took the medication prucalopride for about a week performed better on tests of memory, attention, and thinking speed than those who received a placebo. The drug targets a serotonin receptor found in both the gut and the brain,... Read more ›

NASA's James Webb Space Telescope has revealed new details about the blistering lava planet 55 Cancri e, where temperatures are high enough to melt rock. The data indicate the planet likely has a hydrogen-rich atmosphere shaped by gases escaping from its molten interior, with signs that volcanic outgassing may even create temporary clouds. Read more ›
