Scientists have uncovered how your body actually tells your brain to stop eating when you’re sick. In a new study, researchers found that specialized cells in the gut detect parasites and send signals that ultimately trigger the brain to suppress...
Scientists have identified a key biological system that helps brown fat burn energy by building the networks it needs to function. A protein called SLIT3 splits into two parts, with each piece guiding the growth of blood vessels and nerves inside...
A fossil ape discovered in northern Egypt is reshaping the story of human evolution. The species, Masripithecus, lived about 17 to 18 million years ago and may sit very close to the ancestor of all modern apes. This finding challenges the...
A massive 7.7 magnitude earthquake struck Myanmar in March 2025, but what makes this event extraordinary is what happened next. For the first time, a nearby CCTV camera captured the fault rupture in real time, giving scientists a rare, direct look...
A research reactor in Iran's Khondab was struck by airstrikes, an Iranian official said, stressing there was no radiation leak. The UN warns of a potential "catastrophe" in Lebanon. DW has more.

A new study reveals that high doses of antioxidants—often seen as harmless or beneficial—may actually impact future generations. Male mice given common supplements like NAC produced offspring with subtle but significant facial and skull changes...
Scientists have uncovered a hidden reason why cancer treatments don’t work equally well for everyone. Certain drugs can become trapped inside lysosomes within tumor cells, forming slow-release reservoirs that create uneven drug distribution. This...
Gut bacteria aren’t just passive passengers—they can actively send proteins straight into our cells. Using microscopic injection systems, even harmless microbes can influence immune responses and metabolic pathways. Researchers found these...
Species are vanishing faster than ever, and many are disappearing before scientists even know they exist. Now, an international team is racing against time to uncover hidden life beneath the waves by building a massive open-access genomic database...
Researchers have uncovered a new way to generate exotic oscillation states in tiny magnetic structures—using only minimal energy. By exciting magnetic waves, they triggered a delicate motion that produced a rich spectrum of signals never seen before...
Mars may look like a frozen desert today, but new evidence suggests its watery past didn’t simply fade away quietly—it may have been blasted into space by powerful dust storms. Scientists have discovered that even relatively small, localized storms...
Scientists have uncovered a surprising way to study the harsh space weather around young M dwarf stars. Mysterious dips in starlight turned out to be massive rings of plasma swirling in the stars’ magnetic fields. These structures act like built-in...
Stable sea ice along Alaska’s coast is disappearing faster than expected, with the season shrinking by weeks and even months in recent decades. The ice is forming later in the fall and, in some places, breaking away earlier in spring. This trend is...
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...
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...
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...
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...
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...
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...
