Boston scientists study kids’ internet use: the good, the bad and the weird

This is the Radio Boston rundown for Tuesday, February 7. Yasmin Amer is our host.

• Scientists in Boston are studying what social media does to kids’ brains. We ask one researcher what he’s learned about parenting in the digital age.
• We take a look at the fight against loneliness in Massachusetts. Who’s most at risk, and what’s at stake?
• About half of one percent of venture capital in Massachusetts goes to Black entrepreneurs. We talk with reporter Hannah Green of the Boston Business Journal, along with two venture capitalists, about how that inequality can be addressed.
