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 ...
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 ...
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...
Hunter-gatherers at Poverty Point may have built its massive earthworks not under the command of chiefs, but as part of a vast, temporary gathering of egalitarian communities seeking spiritual harmony...
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 ...
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...
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...
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...
A massive solar storm in May 2024 gave scientists an unprecedented look at how Earth’s protective plasma layer collapses under intense space weather. With the Arase satellite in a perfect observing po...
Scientists have created a live-cell DNA sensor that reveals how damage appears and disappears inside living cells, capturing the entire repair sequence as it unfolds. Instead of freezing cells at diff...
Researchers have uncovered a surprising way the brain switches pain on, revealing that neurons can release an enzyme outside the cell that activates pain signals without disrupting normal movement or ...
A massive long-term study shows that Mediterranean and plant-based diets can help prevent chronic constipation in aging adults. Surprisingly, the benefits weren’t explained by fiber alone. Western and...
Researchers have uncovered a surprising new role for the HSL protein: beyond breaking down fat, it also works inside the nucleus of fat cells to keep them functioning properly. When HSL is missing, fa...
A research team has found that specific immune cells can connect with muscle fibers in a lightning-fast, neuron-like way to promote healing. These cells deliver quick pulses of calcium, triggering rep...
