The pills stocked inside your medicine cabinet may factor into how well you can handle summer heat. Extreme heat can be deadly. As outdoor temperatures sizzle, our bodies jump into action to keep internal temps under control (SN: 8/6/23). Blood rushes to the surface of our skin to release heat as sweat pours onto it, … Read more

Access to clean water is a human right — one that half of the world may not have. Out of the roughly 8 billion people on Earth, more than 4.4 billion lack access to safely managed drinking water, researchers report August 15 in Science. The estimate, based on computer simulations of data from low- and … Read more

Imagine going on a weeklong business trip and not coming home until the following year. That may be the situation for U.S. astronauts Sunita Williams and Butch Wilmore, whose eight-day mission to the International Space Station has already stretched to more than two months and is likely to go even longer. The pair launched to … Read more

Earth’s most famous killer asteroid came from the outer reaches of the solar system, researchers report in the Aug. 16 Science. About 66 million years ago, an asteroid slammed into the sea just off Mexico’s Yucatán Peninsula, forming the Chicxulub crater. That powerful impact may have triggered a mass extinction event on Earth, killing off … Read more

The rotation of the Earth has been measured many times – but never like this. At first, scientists used entangled quantum particles called photons to detect the speed at which the globe spins. The achievement is a step toward investigating one of physics’ greatest mysteries: how the tiny world of quantum physics interacts with gravity. … Read more
