I spoke yesterday with Dan Sichel, a Wellesley economist and a Lady Gaga fan. Both of these facts are relevant for this story.

The U.S. government is about to tweak the way it measures the economy, and some of the biggest changes will affect the entertainment industry.

Under the current system, Sichel told me, Lady Gaga's sales of concert tickets, online songs and CDs all count toward gross domestic product. But the value of the time she spends in the studio working on new songs isn't counted. That's about to change.

In recent weeks, the Associated Press, NPR and the BBC have all had their Twitter accounts hijacked. Hacks of high-profile accounts have real-world consequences, and the security at Twitter is coming under increased scrutiny.

As the social media platform has become an essential news and communication platform globally, it has also become a honey pot for hackers. It's so deliciously attractive, they can't seem to resist.

The investigation into the Boston Marathon bombing continues. Investigators have spoken with the parents of the suspects in Russia. Audie Cornish talks to Dina Temple-Raston about the latest developments.

On Wednesday, the U.S. Supreme Court heard oral arguments in the final cases of the term, which began last October and is expected to end in late June after high-profile rulings on gay marriage, affirmative action and the Voting Rights Act.

Audio from Wednesday's arguments will be available at week's end at the court's website, but that's a relatively new development at an institution that has historically been somewhat shuttered from public view.
