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 of ...

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 touchscreen .. ...
