A nuclear clock prototype hints at ultraprecise timekeeping 

A photograph of scientific equipment, including a laser beam illuminating gas inside a vacuum chamber.

Scientific clockmakers have crafted a prototype of a nuclear clock, hinting at future possibilities for using atomic nuclei to perform precise measurements of time and make new tests of fundamental physics theories. While the definition of a “clock” is scientifically hazy, the prototype is not yet used to measure time. So it technically should be … Read more

More than 100 types of bacteria can thrive in microwave ovens

an photo of a microwave

Even the microwave oven in your kitchen is not immune to bacteria. The radiant environment inside a microwave oven can seem inhospitable to germs. But swabs from microwave ovens in several different areas identified more than 100 bacterial species, researchers report Aug. 7 in Frontiers in Microbiology. This is the first time scientists have documented … Read more
