Scientists have developed a breakthrough “superfood” for honeybees by engineering yeast to produce the essential nutrients normally found in pollen. In controlled trials, colonies fed this specially designed diet produced up to 15 times more young, showing a dramatic boost in reproduction and overall health. As climate change and modern agriculture reduce the availability of natural pollen, this innovation could offer a practical way to support struggling bee populations.

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.

Having both excess belly fat and low muscle mass isn’t just unhealthy—it’s potentially deadly, raising the risk of death by 83%. This condition, called sarcopenic obesity, creates a vicious cycle where fat accelerates muscle breakdown and inflammation. Researchers found it can be identified using simple measurements, not costly medical tests. That means earlier detection—and a real chance to intervene before serious decline sets in.

Using a smartphone with long nails can be frustrating, forcing people to awkwardly tap with their fingertips instead of their nails. Now, researchers are working on a clear nail polish that could change that by turning fingernails into touchscreen-friendly tools. By experimenting with dozens of formulas, they discovered that combining common compounds like taurine and ethanolamine can help nails carry just enough electrical charge for screens to detect a touch.

A sweeping global report finds that migratory freshwater fish are in steep decline, with populations down roughly 81% since 1970. These species depend on long, connected rivers, but dams and human pressures are cutting off their routes. Hundreds of species now need coordinated international protection. Experts say restoring river connectivity is critical to preventing further collapse.

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.

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.

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.

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.

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.

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.

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.

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 have discovered that losing a key protein in small cell lung cancer triggers inflammation that actually helps tumors grow and spread. Even more surprising, it pushes cancer cells into a more aggressive, neuron-like state linked to relapse.

A new prototype could supercharge mass spectrometry by analyzing thousands of molecules at once instead of one by one. The breakthrough boosts sensitivity enough to reveal rare, hidden molecules—potentially transforming fields like drug discovery and single-cell biology.

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.

When temperatures plunge, the risk to your heart rises dramatically. A large U.S. study shows cold weather is linked to far more cardiovascular deaths than heat, accounting for tens of thousands of extra deaths each year. Scientists found the safest temperature sits around 74°F, with danger increasing as conditions get colder—or hotter. As more people live with chronic illnesses, the threat from extreme cold may only intensify.

Flower nectar often contains small amounts of alcohol, meaning pollinators like hummingbirds are drinking it all day long. Despite consuming human-equivalent amounts, they show no signs of intoxication—suggesting a surprising evolutionary tolerance.

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.

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 light-years away.
