Scientists have turned the humble yeast, Saccharomyces cerevisiae, into a laboratory playground for big‑scale genetic tinkering. For years, yeast has been a favorite model organism because its genes can be easily changed and studied. Now researchers are moving beyond simple edits to rewrite entire
Scientists are taking a closer look at two types of chemicals we encounter daily and how they could be influencing teenagers' bodies in unexpected ways. PFAS and phthalates are found in everything from non-stick pans to plastic toys and personal care products. These substances are so common that nea
Scientists have been trying to fix serious damage to the cervix for years, but good solutions are rare. Most methods just provide basic support, failing to help the tissue fully heal when large or complicated injuries occur. Now, researchers tested a fresh idea: mixing human stem cells from umbilica
Scientists have long tried to explain why we sometimes feel like flying, losing teeth, or tumbling off cliffs while asleep. One researcher from Montreal has spent years studying these strange nighttime experiences and has written a book that looks at both ordinary dreams and the frightening ones we
Scientists have found a new way to make hydrogen peroxide directly from water using tiny metal atoms. The trick is to arrange the atoms in a special pattern before heating them up, so that when the metal (cobalt) sits next to three nitrogen atoms and one oxygen atom it works best. This pattern is ca
Scientists are tackling a sneaky problem: invasive snakes that eat native lizards and upset local ecosystems. The California kingsnake, originally from North America, has spread to places like the Canary Islands, where it hunts rare reptiles. Traditional traps catch everything, including harmless lo
Scientists have created a fresh way to help coral reefs survive when the ocean loses oxygen. Instead of waiting for problems, this method uses smart computer models that learn from real data and can adapt as conditions change. The team mixes a machine‑learning map of dissolved oxygen with a detailed
Scientists have found a way to make secure encryption keys that keep working even when the temperature jumps from normal room levels up to 700 °C. The trick uses a special kind of diamond called nitrogen‑incorporated ultrananocrystalline diamond, or n‑UNCD for short. Inside this material are t
Scientists have been warning for years that a warming planet brings more than heat waves. It also spreads diseases once locked in one place. The recent hantavirus scare on a cruise ship off South America shows how quickly tiny changes in temperature can shift danger zones. Argentina has seen a shar
Scientists have discovered that newborn mice already possess a dense web of brain connections, especially in the hippocampus where memory is formed. Instead of building these links slowly after birth, the brain seems to start out with more connections than needed and then prunes away the extras as i
