Satellites Reveal ‘Hot Lightning’ Strikes Are Most Likely To Start Wildfires

Scientists are using new satellite sensor data, combined with info from the terrestrial U.S. National Lightning Detection Network, to help identify the most dangerous lightning strikes. They found that “hot lightning” is the most dangerous as it can ignite wildfires, damage electrical equipment, and even kill people. Slashdot reader Wave723 shares a report from IEEE Spectrum: With new tools, researchers can…

Hawaii Extends Thirty Meter Telescope Permit Amid Protesters

Miniature gravitational-wave detector to be built at Northwestern

A team of physicists and astronomers from Northwestern University is poised to lead gravitational-wave astronomy into its next evolution. The W. M. Keck Foundation has awarded $1 million, which will be used to develop a prototype for a new kind of gravitational-wave detector that is small enough to fit on a tabletop and powerful enough to detect cosmic events that existing…

What Caused the 2019 New York Blackout? Infrastructure.
