Quantum teleportation may be possible between electrons, researchers say. In the quantum world, teleportation involves the transportation of information, rather than the transportation of matter like in science fiction.

Contrary to President Trump’s recent comments, specialists say, recent increases are real, and the virus is like a “forest fire” that will burn as long as there is fuel.
In the end, history may record that the most revealing thing about President Trump’s rally in Tulsa last night was the way it was covered by the all-news networks. CNN, MSNBC, and Fox News had plugged the event as if it were the Pro Bowl. The anchors and reporters vamped for hours with pregame analysis and on-the-scene color shots as the big kickoff approached.

To find prey in the dark, bats use echolocation.
