Earlier this month, the Department of Homeland Security confirmed that Russian hackers have infiltrated the U.S. electric grid. That means they may have the ability to shut down major power plants. The targeted facilities included at least one nuclear power plant and other types of infrastructure as well. Marketplace Tech host Molly Wood spoke with former U.S. Air Force Maj. Gen. Robert Latiff about the strategy behind the attacks.

Facebook has seen better days when it comes to its public image. The Cambridge Analytica scandal is the latest public relations disaster to befall the tech giant, and in response, some users are deleting their accounts. But is that realistic? Marketplace Tech host Molly Wood spoke with Jillian York of the Electronic Frontier Foundation about why quitting Facebook is a privilege that not everyone can afford.   

Two U.S. senators are asking the powerful Senate Judiciary Committee to get Facebook CEO Mark Zuckerberg to testify before Congress. They want Zuckerberg to explain how Facebook handles our personal information and how it let the political data firm Cambridge Analytica harvest detailed information on 50 million Facebook users without their permission. The last time Facebook was asked to appear before Congress, Zuckerberg and Facebook Chief Operating Officer Sheryl Sandberg sent their legal team instead. Marketplace Tech host Molly Wood spoke with Republican Sen. John Kennedy from Louisiana, one of the senators who penned a letter asking Zuckerberg to testify, about what he’d like to hear from Facebook.  

If you’re not Apple, Google or Amazon, the music streaming business is tough. Last week, iHeartMedia filed for Chapter 11 bankruptcy protection. Pandora moved to renegotiate its costly deals with record labels last week, and Spotify is reassuring investors that it can turn a profit as it prepares to go public next month. Marketplace Tech host Molly Wood spoke with Paul Sweeney, media analyst at Bloomberg Intelligence, about why it’s so hard to make money in streaming.      

With enough data, could a company predict what you want? That’s the idea behind psychographic advertising: A company builds a profile of each customer and uses it to manipulate their emotions through marketing. This type of advertising is at the heart of a scandal involving Cambridge Analytica, which used Facebook to get this type of personal data. But how far can this type of advertising go? Marketplace Tech host Molly Wood spoke with Alexandra Samuel of the Harvard Business Review about what psychographic marketing really is and what its limits are.   

There’s more scrutiny around violence and video games at this year’s Game Developers Conference in San Francisco. After the mass shooting at Parkland High School in Florida last month, President Donald Trump called the game industry to the White House and suggested that violence in video games could lead to real-world violence. However, research hasn’t found a link between the two. Marketplace Tech host Molly Wood spoke with Kate Edwards, executive director of Take This, a mental health nonprofit, to find out how game developers are thinking about this in their work. 

AT&T wants to buy Time Warner and the Justice Department isn’t having it. The Justice Department filed a civil antitrust lawsuit against AT&T and Time Warner last November to prevent the merger. The government’s case rests on whether the merger would lessen competition in the entertainment marketplace and harm consumers. The case will go trial next week. Marketplace Tech host Molly Wood spoke with Michael Carrier, a professor of law at Rutgers, about what’s at stake. 

Are scientists prioritizing data collection over reporting harassment? That’s one of the questions that caused University of Illinois anthropologist Kathryn Clancy to examine harassment in research laboratories and field sites.  She found that it’s prevalent in science as much as other fields, and that often researchers don’t know the procedures for reporting incidents. Clancy talks with Marketplace’s Kimberly Adams about the harassment that exists in scientific research, and what universities can do to change it.
