Scientists ran tests to see how tiny, invisible particles might spread if they escaped from a big science lab in Sweden. They focused on what could happen in the worst possible accident—one where cooling fails and tiny radioactive bits could fly into the air. The goal was to track where these partic
Scientists tested a new molecule called WK-13-3D on one of the toughest breast cancers to treat. Instead of trying to poison the cancer cells directly, it tricks them into breaking their own cleanup system. Every cell normally recycles old parts through a process called autophagy. In triple-negative
Scientists picked 25 female lab mice and watched how their stomach and gut bacteria changed after an infection with Helicobacter pylori—the same bug that causes most stomach ulcers and even cancer in humans. For one week the mice hosted the invader, then for another month they got powdered Weizmanni
Scientists who protect animals and plants rely on names to keep track of what is at risk. When new species are found or old ones are re‑named, the list of what needs saving changes. Despite this, no single report shows how the most trusted extinction lists use these names. To investigate, res
Scientists across the United States are feeling the strain of recent federal changes that have shaken up funding, hiring, and research freedom. A survey conducted by a university panel gathered 280 responses from fields such as biology, engineering, and public health. The results show that more than
Scientists across the United States are feeling the bite of delayed federal funding, especially after a series of cuts during the previous administration. One Harvard researcher, who works on the origins of life, once had a bustling lab filled with students and colleagues. Now, after his grant was a
Scientists fed young freshwater turtles different amounts of DEHP—a chemical found in many plastics—for three months. They found that even small doses caused extra damage in the turtles’ blood cells. The higher the dose, the more the damage grew, especially in the cells’ DNA. Some turtles also grew
Scientists recently tested how brief but intense heatwaves affect the red mason bee, a common pollinator. They exposed young bees to three days of high temperatures, matching heat levels seen in the UK in 2022. The bees survived the heat, but something unexpected happened inside them. As adults, mal
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
