– Manuscript – A team of scientists is studying the sound of the forest in Ecuador to learn how artificial intelligence (AI) could follow animal life in recovering environments. When scientists want to measure new forest growth, they can study large areas of land with tools like satellites and lidar. But understanding how fast and in what amount wildlife is returning … [Read more...] about Scientists Try Listening to Learn about Wildlife

– Manuscript – Jennifer Byrne owns a heating and air conditioning repair company in the American city of Philadelphia, Pennsylvania. Air conditioning, or AC equipment, cools the air in a home. To do this, the equipment uses a gas called a refrigerant. While working on AC equipment in a house, Byrne puts gas from the equipment into a special container. The gas is … [Read more...] about Scientists: Chemical Used in Air Coolers Needs Replacing

– Manuscript – A new study suggests changes in world climate and land use are sharply reducing the number of insects needed for pollinating crops. The study looked at thousands of species and areas around the world. It found that the number of pollinating insects dropped by 61 percent during periods of abnormally high temperatures and reduced supply of flowering … [Read more...] about Study: Climate, Land Use Changes Sharply Reduce Pollinating Insects

– Manuscript – Ancient builders across the world created structures that are still standing today, thousands of years later. Roman engineers built thick concrete sea barriers, for example. Mayan builders created sculptures to their gods, and Chinese builders raised walls against invaders. But there are many recent structures that are already starting to fail. The … [Read more...] about Scientists Study Long-lasting Ancient Structures

– Manuscript – New research confirms that a fossil of human footprints found in the U.S. state of New Mexico likely represents the oldest direct evidence of humans living in the Americas. The footprints were discovered at the edge of the remains of an ancient lake in White Sands National Park in southern New Mexico. The research, published recently in Science, suggests … [Read more...] about Study: Footprints in New Mexico May Be Oldest Sign of Humans
