Facebook is grappling with potential bias against its female engineers' work, according to a report from the Wall Street Journal on two studies of the code submitted by female employees at the social network.

Last fall, an unnamed female engineer analyzed internal data and found that women received 35% more rejections of their code than men. This prompted Jay Parikh, Facebook's head of infrastructure, to conduct his own study, though he attributed the gaps to ranking and experience, not gender. Facebook told the Journal that the engineer's study used incomplete data.

What this means: Even assuming that Parikh's study and conclusion are more accurate, it's not good news for Facebook as it suggests that women aren't rising up the ranks at the same rate as men and that there aren't enough female senior engineers. And this isn't isolated to Facebook—women and underrepresented minorities across the tech industry still only make up a very small number of technical and senior roles at companies.

Ethiopia's Nobel Peace laureate cracks down on ethnic violence

The image of a Nobel Peace laureate in military fatigues encapsulates the moment in which Ethiopia finds itself — on the verge of a transition to democracy, a descent into violence or, perhaps, a precarious combination of the two.

Driving the news: At least 166 people were killed after an iconic musician, Haacaaluu Hundeessaa, was murdered last Monday in Addis Ababa, the capital. Prime Minister Abiy Ahmed responded to the violence by sending in troops and shutting off the internet. High-profile opposition leaders were arrested, along with some 2,300 others.

Atlanta Mayor Keisha Lance Bottoms tests positive for coronavirus

Atlanta Mayor Keisha Lance Bottoms said on Monday that she has tested positive for the coronavirus after displaying no symptoms.

Why it matters: Bottoms, one of several Black women on the shortlist to be Joe Biden's running mate, has risen to national prominence in recent months as part of mass protests over racism and police brutality — driven in part by the killing of Rayshard Brooks by Atlanta police.
