Walmart said on Wednesday that customers under 21 would no longer be allowed to purchase firearms from its stores, CNBC reports.

"In light of recent events, we've taken an opportunity to review our policy on firearm sales. Going forward, we are raising the age restriction for purchase of firearms and ammunition to 21 years of age ... We are also removing items from our website resembling assault-style rifles, including nonlethal airsoft guns and toys. Our heritage as a company has always been in serving sportsmen and hunters, and we will continue to do so in a responsible way."
— Walmart statement provided to CNBC

Why it matters: This follows Dick's Sporting Goods' move earlier Wednesday to no longer sell "assault-style" rifles, and a number of other corporate decisions after the Parkland shooting. Walmart said in its statement that the company does not sell "modern sporting rifles" or handguns.

Salesforce's likely acquisition of workplace messaging service Slack — not yet a done deal but widely anticipated to be announced Tuesday afternoon — represents a big gamble for everyone involved.

For Slack, challenged by competition from Microsoft, the bet is that a deeper-pocketed owner like Salesforce, with wide experience selling into large companies, will help the bottom line.

FBI stats show border cities are among the safest

U.S. communities along the Mexico border are among the safest in America, with some border cities holding crime rates well below the national average, FBI statistics show.

Why it matters: The latest crime data collected by the FBI from 2019 contradicts the narrative by President Trump and others that the U.S.-Mexico border is a "lawless" region suffering from violence and mayhem.

The rise of military space powers

Nations around the world are shoring up their defensive and offensive capabilities in space — for today's wars and tomorrow's.

Why it matters: Using space as a warfighting domain opens up new avenues for technologically advanced nations to dominate their enemies. But it can also make those countries more vulnerable to attack in novel ways.
