America’s newest airline will never cram you into a too-tight seat. It won’t charge too much money for too-terrible food. It won’t strand you on the tarmac without explanation.

Today, UPS announced that its drone service is the first of its kind to be recognized by the Federal Aviation Administration as a commercial airline.
When a fight broke out recently in the parking lot of Salt Lake Park, a few miles south of downtown Los Angeles, Cogo Guebara did what seemed the most practical thing at the time: she ran over to the park’s police robot to push its emergency alert button.

The age of quantum computing may have begun not with a flashy press conference, but with an internet leak. According to a paper posted briefly—and presumably mistakenly—to a lab site, physicists at Google have used a quantum computer to perform a calculation that would overwhelm the world’s best conventional supercomputer. Although the specific computation has no known use, the result means scientists have passed a milestone known as “quantum supremacy.”
