Scientists have found a way to make the tiny particles that help fuel cells work better. Instead of mixing the metals together, they grow a thin layer of platinum on tiny cobalt tubes that already have holes in them. This “seeded growth” technique creates a one‑dimensional structure that looks like
A drug that many people take to try and live longer is showing a surprising twist. Scientists expected rapamycin, known for helping transplant patients stay healthy, to boost the good effects of exercise. Instead, research shows it may actually reduce some of those benefits. Rapamycin is already ap
Scientists have spent decades charting how our eyes, ears and skin send signals to the brain. The nose, with its thousands of scent sensors, seemed a chaotic maze. Most researchers thought the receptors were scattered randomly. Two research groups changed that view. They used DNA sequencin
SpaceX is gearing up for a big launch from Kennedy Space Center, where the powerful Falcon Heavy rocket will carry the newest ViaSat-3F 3 satellite into a geosynchronous transfer orbit. The launch window opens at 10:13 a. m. on Wednesday, April 29, and the company has until 11:38 a. m. to push it of
A new study examined the gene activity in nearly a thousand brain samples from people who had died with Parkinson’s disease, dementia with Lewy bodies, multiple system atrophy, progressive supranuclear palsy, corticobasal degeneration, Alzheimer’s disease or no brain disease. The researchers used a
Scientists recently dug deeper into the genetic roots of two ethnic groups in Sichuan, China. They studied 100 people from the Qiang and Yi communities. Their goal? To map out how these groups connect genetically to others nearby. The findings show big similarities between the Qiang, Yi, and other
When the day‑lily Hemerocallis fulva “Shaman” opens, it releases a bouquet that shifts over time. Scientists followed this scent journey by sampling petals at three key moments: the first blush, the peak bloom, and the last sigh. Using modern tools that spot tiny chemicals (volatile organic compo
A new study shows that a dad’s exposure to constant light can hurt his children’s memory. The researchers used male mice and kept them in a 24‑hour light environment. When the offspring were born, only the male pups showed trouble learning and remembered things less well than normal. Female pups see
In many parts of the world, babies grow up hearing a lot or very little talking. Researchers wanted to see if the amount of speech aimed at a child matters for how well babies learn the sounds that make up words. They studied two very different places: a rural highland community in Bolivia where peo
The Environmental Protection Agency once had a powerful research wing that pushed forward science to protect people from air and chemical dangers. In recent years, many of its scientists have been moved or told to retire, shrinking the team from about 1, 500 to just over a hundred. These remaining r
