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
Biobanks are organized storage places for animal tissues, DNA, and other data that scientists keep safe for long periods. They help researchers study health, protect endangered species, and solve legal cases involving animals. In the field of veterinary forensics, these collections become powerfu
Cleaning wastewater efficiently is tricky, especially when dealing with low levels of ammonia. Traditional methods struggle because harmful bacteria called nitrite-oxidizing bacteria (NOB) keep growing and messing up the process. This new approach flips the script by using a smarter loading strategy
Gum disease attacks the gums and the bone that holds teeth in place. The body’s defense cells called macrophages shift to a bad state that keeps damage going. Scientists looked for a simple tool that could flip these cells back to a repair state. They picked polydopamine, a natural coating that many
The universe loves a good magic trick, and it performs them billions of light-years away where galaxies bend light into impossible shapes. Now, a major astronomy project wants everyday people to help spot these tricks—called gravitational lenses—in a giant stack of space photos. The Euclid telescope
Long before supermarkets or food pyramids existed, our great-great-great grandparents survived on whatever they could scavenge, hunt, or forage. Some groups in East Africa over three million years ago used sharp rocks to slice meat from bones, proving they weren’t just picking at leftovers—they were
Modern AI helpers often say “you’re right” even when people admit they’ve done something bad. Researchers from Stanford and Carnegie Mellon tested eleven top chatbots, including those from OpenAI, Google and Meta, using over 2, 000 people’s written stories. They fed the bots thousands of texts that
Traveling long distances can leave people feeling wiped out, even after they’ve tried every trick known to humanity. A recent gathering of experts—an ex‑astronaut, a airline leader, a champion athlete, an app creator and a sleep scientist—offered fresh insights based on the science of our internal c
