Perhaps the hardiest assemblage of lichens and other fungi and algae yet found has been hiding in plain sight in northern Chile’s Atacama Desert. This newly discovered “grit-crust,” as ecologists have named it, coats tiny stones and draws moisture from daily pulses of coastal fog that roll across the world’s driest nonpolar desert. These communities […] More
Moving slowly and stealthily through the Pacific Ocean, a robotic glider with a microphone captured a cacophony of sounds from ships, whales and underwater explosions. The glider’s journey, across 458 kilometers off the Washington and Oregon coast and down to 650 meters, demonstrates that gliders could be effective tools to help map ocean noise levels, […] More
The world is way behind on its commitment to reduce greenhouse gas emissions — and nations need to act immediately if they want to stave off the worst effects of climate change, an international study finds. Humans must reduce emissions by 2.7 percent each year from 2020 to 2030 just to achieve the goal set […] More
Earth’s cooling climate, Science News, November 15, 1969 — The average temperature for the entire Earth rose gradually from the 1880s until the early 1940s. At that time, a cooling trend suddenly set in which is continuing today.… The amount of dust and other particulate matter in the atmosphere has increased dramatically in recent decades, […] More
Plastics can enter the food web at an unexpected point: larval fish as small as the tip of a pencil. Larval fish congregate in ocean slicks — ribbons of calm water that form naturally on the ocean’s surface — to feast on an abundance of prey. Prey-sized plastics also accumulate in these fish nurseries, outnumbering […] More
Power lines could be messing with honeybees by emitting electromagnetic fields that can alter the insects’ behavior and ability to learn. In the lab, honeybees (Apis mellifera) were more aggressive toward other bees after being exposed to electromagnetic fields, or EMFs, at strengths similar to what they might experience at ground level under electricity transmission […] More
Jian Zhong Wang’s home in the southern Chinese city of Nanning is an inviting place. Light spills in through large bay windows, which offer a stunning view of the garden of thick-stemmed banana plants and chest-high cacti. The room is packed with intricately carved furniture: a dining table flanked by eight straight-backed chairs, a coffee […] More
Humpback whales need to eat a lot every day, and some even use their flippers to help snag a big mouthful of fish. Researchers filmed humpbacks (Megaptera novaeangliae) hunting with this tactic, called pectoral herding, off the Alaskan coast. It’s the first time that this behavior has been documented in such detail, the team reports […] More
