This cow uses tools like a primate—and scientists are stunned
A cow named Veronika has stunned scientists by using tools in a flexible and purposeful way. She chooses different ends of a brush depending on the part of her body and adjusts her movements accordingly. This level of tool use is incredibly rare and was previously seen mainly in primates. The finding hints that cows may be much smarter than we assume.
Vivid dreams may be the secret to deeper, more restful sleep
Vivid dreams might be doing more than just entertaining your mind at night. Researchers found that immersive dreaming can actually make sleep feel deeper and more refreshing, even when brain activity is high. Surprisingly, people reported their deepest sleep after intense dream experiences, not just during quiet, inactive periods. This suggests dreams may play a key role in helping us feel truly rested.
Scientists found a bug that generates its own heat in freezing cold
Snow flies have an unexpected way of surviving freezing temperatures. They produce antifreeze proteins to block ice formation and can even generate their own heat. Scientists also found that their genes are unusually unique, and they feel less cold-related pain than other insects. These combined traits let them stay active in conditions that would freeze most species.
Deepfake X-rays are so real even doctors can’t tell the difference
Deepfake X-rays created by AI are now convincing enough to fool both doctors and AI models. In tests, radiologists had limited success identifying fake images, especially when they didn’t know they were being shown. This opens the door to risks like fraudulent medical claims and tampered diagnoses. Experts say stronger safeguards and detection tools are critical as the technology advances.
Metformin’s hidden brain pathway revealed after 60 years
A major discovery reveals that metformin works not just in the body, but in the brain. By switching off a key protein and activating specific neurons, the drug lowers blood sugar through a previously hidden pathway, opening new doors for diabetes treatment.
Astronomers solve 50-year mystery of a naked-eye star’s extreme X-rays
A star you can see with the naked eye has kept astronomers guessing for decades with its unusually powerful X-rays. Now, thanks to highly precise observations from Japan’s XRISM space telescope, scientists have finally uncovered the source: a hidden white dwarf companion pulling in material and generating extreme heat. This discovery not only solves a 50-year-old mystery surrounding Gamma Cassiopeiae, but also confirms the existence of a long-predicted type of binary star system.
Project Hail Mary meets reality: 45 planets could harbor alien life
Astronomers have narrowed down the cosmic search for life, identifying fewer than 50 rocky planets among thousands of known exoplanets that may have the right conditions to support life. Using new data from ESA’s Gaia mission and NASA archives, researchers pinpointed worlds in the “habitable zone,” where temperatures could allow liquid water to exist. Some of the most intriguing targets include nearby systems like TRAPPIST-1 and Proxima Centauri, offering tantalizing possibilities just dozens of
Scientists open a million-year-old time capsule beneath New Zealand
Deep inside a cave, scientists uncovered fossils from 16 species, including a newfound kākāpō ancestor that may have been able to fly. These remains reveal that New Zealand’s ecosystems were constantly disrupted by volcanic eruptions and rapid climate shifts. Long before humans, waves of extinction and replacement reshaped the islands’ wildlife. It’s a rare window into a missing chapter of natural history.
Scientists find immune cell linked to long COVID fatigue and symptoms
Long COVID remains a frustrating medical mystery, affecting up to 1 in 10 people long after the initial infection fades. Now, scientists have uncovered a crucial clue hidden deep within the immune system. By analyzing individual immune cells, they identified a distinct molecular state in key white blood cells—especially common in patients who initially had mild or moderate COVID.
Scientists discover “overflow valve” in cells linked to Parkinson’s Disease
Researchers have identified a crucial ion channel, TMEM175, that acts like an overflow valve in the cell’s recycling system. It regulates acidity inside lysosomes, ensuring they function properly. When TMEM175 is faulty, toxic buildup can occur, contributing to diseases like Parkinson’s. This breakthrough reveals a promising new target for future therapies.
What you do in midlife could reveal how long you’ll live
By closely monitoring fish throughout their lives, researchers found that simple behaviors in midlife—like movement and sleep—can predict lifespan. Fish that stayed active and slept mostly at night tended to live longer, while those slowing down earlier lived shorter lives. Surprisingly, aging didn’t unfold smoothly but in sudden jumps between stages. The work suggests that tracking daily habits in humans could reveal early clues about how we age.
24 new deep-sea species found including a rare new branch of life
In a remarkable deep-sea breakthrough, researchers have discovered 24 new species of amphipods in the Pacific’s Clarion-Clipperton Zone—including a rare, entirely new superfamily. The findings reveal previously unknown branches of life and push the boundaries of how deep these creatures are known to live.
