Uber will stop using its Greyball tool to evade officials. The company is investigating the use of ‘Greyball,’ a program that uses data to identify users who may be violating Uber’s terms of service. This has included targeting law enforcement and government officials in cities where Uber is more foe than friend; when regulators attempt to use the app, they’re served a fake version that displays nonexistent, or no available, cars. Uber is now prohibiting the tool’s use for that purpose and investigating the other ways Greyball is employed.

And more Uber news: In yet another executive departure, Uber’s AI Labs head Gary Marcus is stepping aside after only four months. He’ll take on a position as special advisor for the company’s AI efforts. Marcus came on board with the December acquisition of his company, Geometric Intelligence.

RadioShack has declared bankruptcy (again): For the second time in nearly as many years, the struggling electronics chain has filed for bankruptcy. The company will close about 200 stores and consider options for its remaining 1,200.

Harvard Law is accepting GRE scores instead of relying solely upon the LSAT, in an attempt to diversify its applicant pool. Harvard Law is only the second accredited university to make the switch, following the University of Arizona James E. Rogers College of Law’s decision last year.

The US workforce is shrinking: The native-born US workforce began to shrink last year, according to Pew Research, and projected growth through 2035 is driven by immigration. Shrinking workforces can be precarious for national economies: “Not only is it harder to produce more wealth with fewer people,” explains Axios, “but the incentive for corporations to invest in the future is reduced when they know they'll have fewer potential customers tomorrow than they have today.”

A group of investors led by Edward Bronfman Jr. has decided to walk away from Time Inc. The publisher of Sports Illustrated, People, Time, and other titles had previously rejected two offers from Bronfman, including one late last year that would have valued the company at $1.8 billion. While Time’s board hasn’t yet decided whether to pursue a sale, the company requested formal bids by this week.

Samsung’s heir goes on trial: Jay Y. Lee’s “trial of the century” began today, and the de facto head of Samsung (and four other execs) formally denied bribery charges. The charges of bribery and embezzlement “strike at the heart of the deep ties between the South Korean government and powerful family-controlled businesses, a source of growing public resentment,” says The New York Times.
