It is predicted to cause more extensive damage than the 2011 Great East Japan Earthquake and fatalities may exceed 320,000. It is believed that this megathrust earthquake will occur when the strain energy that…

Credit: AI-generated image The Los Angeles school district on Wednesday unveiled a much-awaited AI tool named "Ed" to serve as a new student adviser, programmed to tell its young users and their parents about grades, tests results and attendance—while giving out assignments, suggesting readings and even helping students cope with nonacademic matters. …

Brightening Earth’s clouds so that they reflect more sunlight just might cool the planet — that is if we can figure out how to do it without causing any unintended harm. To test the theory out, a group of over 30 leading scientists have written up a research road map that was published in the journal Science Advances yesterday. The paper focuses on how to approach attempts to artificially shade Earth’s surface with marine clouds by spraying saltwater into the air from ships, a strategy called marine cloud brightening…

Clockwise from top left: Images of the 2020 Midwest Derecho from radar and microwave satellite observations show similar patterns, which are obscured in infrared brightness satellite observations. A technique to combine microwave and infrared satellite observations could improve forecasts of severe weather, and may be especially useful in areas that lack ground-based weather monitoring radar networks, the scientists said.
