All Headlines
Popular sugar substitute linked to brain damage and stroke risk
A widely used sugar substitute found in everything from keto snacks to diet drinks may not be as harmless as it seems. New research shows that erythritol can disrupt brain blood vessel cells, reducing their ability to relax, increasing harmful oxidative stress, and impairing the body’s ability to break down clots. These changes create conditions that could raise stroke risk, even at typical consumption levels.
After 20 years, scientists finally explain the Crab Pulsar’s strange “zebra stripes”
For decades, astronomers have been puzzled by strange “zebra stripe” patterns in radio waves from the Crab Pulsar — bright bands separated by complete darkness. Now, new research suggests the answer lies in a cosmic tug-of-war between gravity and plasma. The pulsar’s plasma spreads light apart, while gravity bends it back together, creating interference patterns that form the striking stripes.
This new carbon material could make carbon capture far more affordable
Scientists have created a new kind of carbon material that could make carbon capture much cheaper and more efficient. By carefully controlling how nitrogen atoms are arranged, they found certain structures capture CO2 better and release it using far less heat. One version works at temperatures below 60 °C, meaning it could run on waste heat instead of costly energy. The discovery offers a powerful new blueprint for next-generation climate technology.
Scientists discover why your appetite suddenly disappears when you’re sick
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 appetite. This process builds over time, explaining why you may feel fine at first but then suddenly lose interest in food as an infection takes hold.
Scientists discover a hidden system that turns brown fat into a calorie burner
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 brown fat. These structures allow the tissue to pull in nutrients and rapidly convert them into heat instead of storing them as fat.
Scientists say we’ve been looking in the wrong place for human origins
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 long-standing focus on East Africa. Instead, it points to northern Africa and nearby regions as a possible birthplace of apes.
Watch the Earth split in real time: Stunning footage captures a 2.5-meter fault slip in seconds
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 at how the Earth moves during a major quake. Researchers discovered that the ground shifted 2.5 meters in just 1.3 seconds, confirming a rapid, pulse-like rupture and revealing that the fault path was slightly curved.
Scientists uncovered the nutrients bees were missing — Colonies surged 15-fold
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.
Scientists discover “alien space weather stations” that could reveal habitable planets
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 space weather monitors, revealing how energetic particles affect nearby planets. The findings could reshape how we think about whether planets around these common stars can survive—or even host life.
Scientists discover bizarre new states inside tiny magnetic whirlpools
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 in this system. The finding challenges existing assumptions and could help connect different types of technologies, from conventional electronics to quantum devices. It’s a small effect with potentially huge implications.
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.
Scientists stunned as Mars dust storms blast water into space
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 can hurl water vapor high into the atmosphere, where it breaks apart and escapes.
