In 2019, Walmart started working with a company called Gatik to test autonomous delivery trucks on a two-mile route between a fulfillment center and a store in Bentonville, Arkansas. After those vehicles logged more than 70,000 miles with a human driver there to make sure nothing went wrong, Walmart and Gatik say they're ready for a new challenge. Next year, there won't be any human drivers in the trucks. That milestone will make Gatik one of the first companies in the space to operate a fully autonomous route in this way. As the startup itself is quick to point, it has its simplified approach to thank for the achievement.

Mental health professionals in the U.S. have reported that the all-encompassing coverage of the president has induced anxiety and depression, or post-election stress, in many of their patients.
