Aging may be partly fueled by immune cells losing their ability to clear away damaged, inflammation-promoting cells. Blocking a single receptor restored that cleanup process in mice, reducing inflammation and helping their organs, muscles, and memory remain remarkably youthful.
China is rapidly expanding its ability to harness renewable energy sources.
Star formation across the universe has fallen dramatically over the past 4.5 billion years, but astronomers have uncovered a surprising twist: the supply of neutral hydrogen, a key ingredient for making stars, has barely declined. Using China’s FAST radio telescope and data from roughly 2.5 million galaxies observed by DESI, researchers found that star formation was about 2.5 times higher 4.5 billion years ago, while neutral hydrogen levels were only about 1.4 times higher.
September’s sky features brilliant Venus, the Milky Way’s hazy center, and the seasonal turning point of the equinox. The month ends with a glowing Harvest Moon rising near Saturn and faint Neptune.
Elephant Butte Reservoir, New Mexico’s largest reservoir, plunged to just 1.4 percent capacity in July 2026 after years of extreme drought and record early snowmelt. The dramatic decline exposed long-submerged debris and underscored the growing strain on Rio Grande water supplies used by farms in New Mexico and Texas.
Some of the attention patterns that make ADHD challenging may also help spark creativity by allowing the brain to explore more ideas and unexpected connections. Researchers think creative activities could potentially channel this “defocused attention” while helping strengthen the brain systems involved in focus and self-control.
Sitting for long, uninterrupted stretches may carry greater health risks than sitting the same amount of time in shorter bouts. Researchers found that each extra hour of prolonged sedentary behavior was associated with a 9% higher risk of cancer death. Breaking up sitting with movement showed the opposite pattern, while replacing an hour of prolonged sitting with light activity was linked to a 12% lower risk.
The world is set to blow past the Paris Agreement’s longtime threshold “within the next few years,” according to a new report
A hexagon darkens the clouds over Saturn’s north pole. Now, astronomers have found a similarly shaped atmospheric wave at the other pole.
After one of the worst natural disasters in the region’s history, attention is turning to the looming super El Niño
The strange structure appears to have formed recently, but nobody can explain exactly why
The Trump administration has so far been silent on flu, COVID and RSV vaccine guidance for the coming season, even as these diseases kill thousands of people every year
“Broken heart syndrome” can mimic a heart attack so closely that patients often need invasive testing to tell the difference. Researchers have now developed the BioTAK score, which combines biological sex with blood biomarkers to identify the condition before cardiac catheterization. In a validation study of nearly 1,800 patients, it correctly classified almost 90% of participants.
Giving old mice semaglutide—commonly sold as Wegovy or Ozempic—extends their lifespan remarkably, a new study finds
A recent CDC analysis says that, between 2016 and 2024, the rate of high blood pressure among pregnant women rose by 73 percent
Solar sails pushed by powerful lasers could reach incredible speeds, but relativity may eventually make the light itself work against them. At around 75% of the speed of light, scattered photons can begin creating drag, adding a surprising obstacle to interstellar travel.
Persistent financial hardship in early and middle adulthood was linked to poorer thinking skills by the 50s and more signs of brain aging later in life. Researchers say years of chronic stress and financial worry may gradually take a toll on the brain.
The biggest fibromyalgia genetics study yet zeroed in on 26 genetic risk factors for the pain disorder, including one in the Huntington's disease gene.
A floating island in a Canadian reservoir moved more than 30 kilometers across the water—here’s why
Brain changes associated with Alzheimer’s may begin at least seven years before amyloid plaques become detectable with current PET scans. Researchers uncovered the signal by tracking healthy older adults with repeated brain imaging over nearly 20 years. The discovery could help scientists identify Alzheimer’s earlier and suggests that important disease processes may start before visible plaque buildup.
