Magnetism drives metals to insulators in new experiment

Like all metals, silver, copper, and gold are conductors. Electrons flow across them, carrying heat and electricity. While gold is a good conductor under any conditions, some materials have the property of behaving like metal conductors only if temperatures are high enough; at low temperatures, they act like insulators and do not do a good job of carrying electricity. In other words, these unusual...

Facebook had hoped that the board would decide how to handle...

The U.S. Government’s Long-Awaited UFO Report Is Here. Its Findings? ¯\_(ツ)_/¯

The U.S. Navy pilots flying maneuvers in their F/A-18 Super Hornets in 2015 did not have to wait for yesterday’s leak of the classified government report on unidentified aerial phenomena (UAP)—better known as UFOs—to know that they were seeing things they could not explain outside their windscreens. The objects were, yes, saucer-shaped, and they were bobbing, darting and...
