In a new installment of its "Hard Questions" series, Facebook acknowledges that social media can have negative (or positive) effects on people, depending on how they use it.

Why it matters: This might be the first public acknowledgment from the company that its product — and category in general — can have detrimental effects on people.

Facebook is also addressing the topic shortly after two former executives publicly criticized the company for what they described as exploiting human psychology.

Good and bad use, according to research cited by Facebook:

  • Bad: Passive use of social media — reading information without interacting with others — makes people feel worse. Clicking on more links or "liking" more posts than the average user also leads to worse mental health, according to one study.
  • Good: Active use — interacting with people, sharing messages, posts, comments, and reminiscing about past interactions — is linked to improved well-being.
  • It takes two: Interacting with other users is key, according to research. Simply posting on Facebook without interacting with other people isn't enough.

But: This isn't a capitulation from Facebook, admitting that it may be doing some harm. Instead, the company is simply telling us that we just need to use its social network in more positive ways.

Salesforce rolls the dice on Slack

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.
