right Now , Antarctica and the surrounding waters are surprisingly free of invasive species. However, according to new research, this situation may change in the not too distant future, thanks to a shocking level of connectivity with ports around the world. Ships can accidentally carry a wide range of marine life, which in turn can …

Today, NASA and NOAA down Annual Analysis From global temperatures: Last year was tied to 2018 as the sixth warmest year on record, but it’s much colder than 2020. A good sign, isn’t it? Yes No. never. “It’s easy to focus on this year-to-year variability,” says Bridget Segers, an oceanographer at NASA. “But it’s important …

So Dwyer and his team turned to the Low Frequency Array (LOFAR), a network of thousands of small radio telescopes in the Netherlands. LOFAR usually stares at distant galaxies and exploding stars. But according to Doerr, “it just so happens to work well for measuring lightning, too.” When thunderstorms roll in, there’s a little useful …

Just as medicine Care evolved from bloodletting to germ theory, and the medical spaces inhabited by patients were transformed as well. Today, architects and designers are trying to find ways to make hospitals more comfortable, hoping that comfortable spaces will lead to a better recovery. But building for healing involves just as much empathy as …

But oyster harvesting was not easy. At low tide, oyster reefs are surrounded by sticky mud that sometimes reaches the thigh. The shells themselves are sharp and covered with infection-causing bacteria. This made heavy gloves and a strong balance essential when maneuvering around exposed reefs. Fossilized gray oyster shells, rough and often mottled with clumps, …

sometimes the universe Too complicated to analyze. Heck, if you take a tennis ball and throw it across the room, even that is pretty complicated. After it leaves your hand, the ball has a gravitational interaction with the ground, causing it to accelerate toward the ground. The ball rotates as it moves, which means that …

during the pandemic, Many people have barely left their neighborhoods, let alone their time zones. But vaccinations are available, cabin fever is rampant, and the holiday travel season is just around the corner. And so, inevitably, it is jet lag. The human internal timekeeping device, scientifically known as the circadian clock, is a mighty force. …

People should get hurt By climate change compensated? From hurricanes and floods to heat waves and droughts, Research has shown That many disasters are already being exacerbated, or increased probability, by climate change. Climate events are slow to appear Like sea level rise, ocean acidification, loss of farmland or receding glaciers – sea level rise …

first detection From gravitational waves In 2016, he provided a decisive confirmation of Einstein’s general theory of relativity. But another astonishing prediction remains uncertain: according to general relativity, each gravitational wave should leave an indelible imprint on the structure of spacetime. It must permanently strain space, clearing the gravitational wave detector mirrors even after the …
