The race to build data centers in space is gaining momentum as AI drives unprecedented demand for computing power. Orbital facilities could tap into abundant solar energy and avoid many of the environmental challenges faced on Earth. Yet space ...
Scientists may have uncovered a hidden trigger behind Alzheimer's disease. Instead of plaques being the root cause, amyloid beta appears to interfere with tau, a protein that helps keep neurons functioning properly. This disruption could set off the ...
A new study suggests Southern California's major fault system is more stressed than at any point in the last 1,000 years. Researchers found that the Cajon Pass, where the San Andreas and San Jacinto faults meet, could act as an "earthquake gate" that ...
A historic lack of snow in the Gila River watershed has left Arizona's San Carlos Reservoir less than 1% full, triggering a massive fish kill and an indefinite closure. Despite the bleak conditions, heavy summer rains could help the reservoir rebound ...
Plague was already a deadly killer 5,500 years ago, long before cities, farming, or the rat-infested conditions usually linked to historic outbreaks. By analyzing ancient DNA from hunter-gatherer cemeteries in Siberia, researchers discovered early .. ...
A new theory suggests the universe is constantly recording its own history in the fabric of spacetime. If correct, this cosmic memory could help solve some of the biggest puzzles in physics, from black holes to dark matter and the universe's ultimate ...
A new study from Northern Arizona University is raising red flags about a widely used global emissions database from Climate TRACE, a consortium co-founded by Al Gore. Researchers found that the database may be dramatically undercounting carbon ...
A major study of Australian native bees found that stem-nesting species may be the first to feel the impact of climate change. Unlike bees that nest underground, they have few ways to escape dangerous heat. Researchers also discovered that tropical . ...
A major study of more than 112,000 people found that eating foods containing common preservatives may be linked to a higher risk of high blood pressure and heart-related diseases. Researchers tracked participants for up to eight years and discovered ...
Scientists have taken a surprising step toward unlocking regeneration in mammals, showing that the ability to rebuild complex body parts may not be lost after all--it may simply be switched off. Using a two-stage treatment, researchers redirected the ...
