Scientists know that upward currents of warm air assist birds in flight. To understand how birds find and navigate these thermal plumes, researchers used reinforcement learning to train gliders to autonomously navigate atmospheric thermals. The research highlights the role of vertical wind accelerations and roll-wise torques as viable biological cues for soaring birds. The findings also provide a navigational strategy that directly applies to the development of UAVs.
Water covers most of the globe, yet many regions still suffer from a lack of clean drinking water. If scientists could efficiently and sustainably turn seawater into clean water, a looming global water crisis might be averted. Now, inspired by origami, the Japanese art of paper folding, researchers have devised a solar steam generator that approaches 100 percent efficiency for the production of clean water. They report their results in ACS Applied Materials & Interfaces.
Princeton geologists used tiny zircon crystals found in volcanic ash to rewrite the timeline for the eruptions of the Columbia River flood basalts, a series of massive lava flows that coincided with an ancient global warming period 16 million years ago.
Imperial experts have predicted that sustained Antarctic warming of just 2°C could melt the largest ice sheet on earth.
NASA's Aqua satellite provided an infrared look at fading Post-Tropical Cyclone Florence's clouds, revealing where the strongest thunderstorms were located. Those strong thunderstorms stretched from the Mid-Atlantic to New England.
NASA's Aqua satellite provided an infrared look at Tropical Depression Joyce and found wind shear was pushing the bulk of clouds and showers to the east of the center.
Scientists have known for years that warming global climate is melting the Greenland Ice Sheet, the second largest ice sheet in the world. A new study from the Woods Hole Oceanographic Institution (WHOI), however, shows that the rate of melting might be temporarily increased or decreased by two existing climate patterns: the North Atlantic Oscillation (NAO), and the Atlantic Multidecadal Oscillation (AMO).
While scientists fear that rising temperatures could unleash a 'bomb' of carbon from Earth's soil carbon reservoirs, a new FSU study suggests these reservoirs might actually be more stable than predicted.
Nearly 13,000 years ago, pines in southern France experienced a cold snap, which scientists have now reconstructed. The study about the consequences of a drastic climate change event in past and its implications for our future will be published tomorrow in Scientific Reports. The authors are from GFZ Potsdam, Berlin, the UK, Switzerland, and France.
On Sunday, Sept. 16, 2018, Typhoon Mangkhut had made landfall in southern China and Hurricane signal #10 was still in force. NASA's Aqua satellite passed over the storm and captured an image that showed the storm after landfall.
