In the weeks that followed, the deadly event drove hundreds of thousands of people to relocate from the surrounding area, which is still a deserted "exclusion zone" today. https://phys.org/news/2023-03-chernobyl-history-worst-nuclear-disaster.html Earth Sciences Tue, 21 Mar 2023 13:26:39 EDT news598623994 The Tonga volcanic eruption unleashed explosive forces that dwarfed the power of the Hiroshima atomic bomb, NASA scientists have said, as survivors on Monday described how the devastating Pacific blast "messed up our brains". https://phys.org/news/2022-01-tonga-eruption-equivalent-hundreds-hiroshimas.html Environment Mon, 24 Jan 2022 04:31:45 EST news562221101 A team of researchers with the Chinese Academy of Sciences has carried out an assessment of possible safety issues tied to the rise of the second nuclear era. In their paper published in Proceedings of the National Academy of Sciences, the group describes the factors that led to the rise of a second nuclear era and possible safety concerns that need to be addressed. https://phys.org/news/2019-08-safety-issues-nuclear-era.html Social Sciences Tue, 20 Aug 2019 09:50:01 EDT news485513267 At precisely 11:48 am on December 18, 2018, a large space rock heading straight for Earth at a speed of 19 miles per second exploded into a vast ball of fire as it entered the atmosphere, 15.9 miles above the Bering Sea. https://phys.org/news/2019-03-powerful-meteor-satellites.html Space Exploration Tue, 19 Mar 2019 17:29:17 EDT news472235349 Atmospheric physicist Nick Gorkavyi missed witnessing an event of the century last winter when a meteor exploded over his hometown of Chelyabinsk, Russia. From Greenbelt, Md., however, NASA's Gorkavyi and colleagues witnessed a never-before-seen view of the atmospheric aftermath of the explosion. https://phys.org/news/2013-08-world-days-nasa-tracks-chelyabinsk.html Earth Sciences Wed, 14 Aug 2013 17:42:07 EDT news295720911 A scientist claiming to work for the Atomic Energy Organisation of Iran told a Finnish cyber-security group that Tehran's nuclear programme had been the victim of a new cyber attack, the group said Wednesday. https://phys.org/news/2012-07-finnish-firm-cyber-iran.html Internet Wed, 25 Jul 2012 17:06:06 EDT news262454761 In the middle of World War II, Secretary of War Henry Stimson asked Treasury Secretary Henry Morgenthau if he could borrow some of the government's silver on repository in West Point, N.Y. With metal in high demand for weaponry, silver was needed for a top-secret project. In this case it was silver's electrical properties, not its monetary value which made it important. The secret project was being carried out at several undisclosed locations and required immense resources. https://phys.org/news/2010-01-silver-crucial-wwii.html Materials Science Wed, 13 Jan 2010 18:30:02 EST news182628141 Magnetic reconnection could be the Universe's favorite way to make things explode. It operates anywhere magnetic fields pervade space--which is to say almost everywhere. On the sun magnetic reconnection causes solar flares as powerful as a billion atomic bombs. In Earth's atmosphere, it fuels magnetic storms and auroras. In laboratories, it can cause big problems in fusion reactors. It's ubiquitous. https://phys.org/news/2009-08-honey-blew-tokamak.html General Physics Mon, 31 Aug 2009 15:09:20 EDT news170949564
