Researchers discovered that the common amino acid arginine can block harmful Aβ aggregation and reduce its toxic effects in Alzheimer’s disease models. In flies and mice, oral arginine lowered plaque ...
Scientists have uncovered a long-missing piece of the volcanic puzzle: rising magma doesn’t just form explosive gas bubbles when pressure drops—it can do so simply by being sheared and “kneaded” insid...
Migratory birds that fill North American forests with spring songs depend on Central America’s Five Great Forests far more than most people realize. New research shows these tropical strongholds shelt...
A first-of-its-kind trial is testing adult stem cell transplants for advanced dry macular degeneration. Early results show the treatment is safe and can significantly improve vision, even in severely ...
New measurements of radio galaxies reveal that the solar system is racing through the universe at over three times the speed predicted by standard cosmology. Using highly sensitive data from multiple ...
Researchers uncovered how estrogen subtly reshapes learning by strengthening dopamine reward signals in the brain. Rats learned faster when estrogen levels were high and struggled when the hormone’s a...
A massive real-world study comparing tirzepatide and semaglutide reveals both drugs deliver strong, early cardiovascular protection—reducing heart attack, stroke, and death in adults with type 2 diabe...
People who smoke only a couple of cigarettes a day still face surprisingly high risks of heart problems and early death. A large review of long-term studies shows that even very light smokers can see ...
Scientists discovered that deep earthquake faults can heal far faster than expected, sometimes within hours. Slow slip events in Cascadia reveal repeated fault movements that only make sense if the fa...
Around 115 million years ago, northern Australia’s seas hosted a colossal shark that rewrites what we thought we knew about early ocean predators. New fossil discoveries show that modern-type sharks w...
Researchers discovered that copper oxide catalysts form metallic copper mid-reaction, triggering a dramatic boost in ammonia output. The insight offers a roadmap for designing cleaner, more efficient ...
Scientists have uncovered a surprising second type of lion roar, using AI to decode vocal signatures with remarkable precision. This breakthrough sheds new light on how lions communicate and offers a ...
A new nasal-delivered nanotherapy shows promise against aggressive glioblastoma tumors. By activating the STING immune pathway using gold-core spherical nucleic acids, researchers were able to reach t...
Scientists flew the XL-Calibur telescope on a high-altitude balloon to measure polarized X-rays from Cygnus X-1. These measurements reveal details about the chaotic, superheated material swirling arou...
Worker bees stage coordinated revolts when viral infections weaken their queen and lower her pheromone output. This disruption drives many of the queen failures that beekeepers struggle with today. Fi...
Scientists discovered that lowering a specific molecule helps microglia switch into a protective state that quiets brain inflammation in Alzheimer’s. A small group of these cells seems to have an outs...
Water trapped inside tiny molecular cavities behaves in a surprisingly energetic way, pushing outward like people crammed in an elevator. When a new molecule enters these narrow spaces, the confined w...
Researchers have pinpointed a super-Earth in the habitable zone of a nearby M-dwarf star only 18 light-years away. Sophisticated instruments detected the planet’s gentle tug on its star, hinting at a ...
Ideas about Vikings and Norse mythology come mostly from much later medieval sources, leaving plenty of room for reinterpretation. Over centuries, writers, politicians, and artists reshaped these stor...
Researchers taught young loggerhead turtles to associate certain magnetic fields with feeding, prompting a distinctive dance when they recognized the signal. After a magnetic pulse briefly disrupted t...
