Back in January, a U.S. Senate committee probed executives from Meta, TikTok, X, Snap and Discord about social media’s effect on kids. During a heated exchange with Missouri Sen. Josh Hawley, Meta CEO Mark Zuckerberg stood, turned and apologized to families of victims who were sexually exploited on social media platforms. No federal legislation on the issue has become law, but some states are taking the lead. New York just passed two laws aimed at regulating social media, and California Attorney General Rob Bonta is pushing similar legislation in his state. Marketplace’s Lily Jamali sat down with Bonta to ask about what his state is doing to protect social media’s youngest users.

Telling truth from fiction online has become a lot harder since the AI boom kicked off a year and a half ago. An estimated 40 deepfake detection startups say they have a solution, but so far none can deliver 100% reliable detection. One organization taking on the challenge is TrueMedia.org. Marketplace’s Lily Jamali spoke with Oren Etzioni, its founder and longtime AI researcher, about what sets his organization’s system apart from the rest.

NASA’s Hubble Space Telescope has been exploring the cosmos for the past three decades, helping scientists understand how fast the universe is expanding and with that, its age. In December 2021, NASA launched the James Webb Space Telescope to further that research. The bonus: All those stunning images from outer space. Marketplace’s Lily Jamali spoke with Adam Riess, a physicist at Johns Hopkins University who shared the 2011 Nobel Prize in physics. He said the Webb telescope has confirmed what Hubble first pieced together: Our universe is expanding faster than first predicted.  

The Summer Olympics, which kick off in Paris next month, are set to bring more than 10,000 athletes and an estimated 15 million spectators to the French capital. Officials hope to keep sports at center stage, but behind the scenes, they’re preparing to fend off cyberthreats in high volume. In recent years, several Olympic host cities have faced and managed cyberattacks, but as Antoaneta Roussi, cybersecurity reporter at Politico, tells Marketplace’s Lily Jamali, this year could be worse.

Artificial intelligence has been used to help translate election candidates into hundreds of different languages — but also to create deepfakes of Bollywood stars and spread false news. The BBC’s Arunoday Mukharji reports.

In the early days of OpenAI’s ChatGPT, a chatbot query required about 10 times the electricity of a typical Google search. And as people do more with generative artificial intelligence, we’re going to burn through even more power. Plus, the ’80s are back — on TikTok. A new dance trend is getting Gen X parents to show their Gen Z kids how they danced back in the day, to the tune of Bronski Beat’s “Smalltown Boy.” Also this week, The Wall Street Journal reported that consulting and professional services giant PricewaterhouseCoopers is now OpenAI’s largest customer and the first reseller of ChatGPT’s enterprise tier, which is aimed at businesses. Marketplace’s Lily Jamali spoke with Jewel Burks Solomon, managing partner at Collab Capital, about these headlines for this week’s Tech Bytes: Week in Review.

A law signed by President Joe Biden last month would force TikTok to divest from its Chinese parent company, ByteDance, or be banned in the United States because of national security worries. And it’s making a lot of small-business owners anxious. We hear their stories.

Sharon Lerner has been reporting on “forever chemicals” for the better part of a decade. These manmade compounds — known as PFAS for short — resist oil, water and heat, take an incredibly long time to break down in nature, and have been used widely in products like Scotchgard, Teflon and firefighting foam. Lerner has focused part of her work on understanding the flow of information inside manufacturers like 3M. By the 1970s, Lerner says, Minnesota-based 3M had established that they were toxic in animals and were accumulating in humans’ bodies. But who inside 3M knew? And what did they know? Reporting for ProPublica, a nonprofit investigative news site, Lerner got a complicated answer after coming across a former 3M scientist named Kris Hansen. Marketplace’s Lily Jamali spoke with Lerner about her recent investigation.

When it comes to combating election-related misinformation online, sometimes the real world is the best place to start, but it isn’t always easy. On this week’s installment of “Marketplace Tech’s” limited series “Decoding Democracy,” Lily Jamali and senior Washington correspondent Kimberly Adams discuss the personal side of misinformation, take questions from colleagues and hear from experts about best practices for talking with loved ones about this sometimes sensitive topic.

A team from the University of Glasgow in Scotland is developing a robot guide dog aimed at helping the visually impaired find their way around. They’re calling the AI-powered device the RoboGuide. The BBC’s Shiona McCallum brings us along on her visit with one of the robodogs and its handler, Dr. Wasim Ahmad.

Proceeding without permission is a time-tested practice in some corners of Silicon Valley. Well, it’s not working out so well for OpenAI. Actress Scarlett Johansson said this week the company approached her twice to voice a new AI assistant for ChatGPT-4o. She declined, only to find it had used a voice that sounds “eerily” like hers. Plus, on Capitol Hill, a House subcommittee held a hearing that could decide the future of Section 230, the provision that largely governs the internet today. We’ll explain why chatbots have entered the chat on Section 230’s future. But first, a new report by former tech company officials and academic researchers finds far-right extremist militias are once again organizing on Facebook ahead of November’s presidential election. They recommend platforms ramp up content moderation to avoid fueling political violence. Marketplace’s Lily Jamali is joined by Maria Curi, tech policy reporter at Axios, for her take on this week’s tech news. Our May fundraiser ends Friday, and we need your help to reach our goal.

Ever since NASA’s Perseverance rover landed on Mars three years ago, it’s been collecting rocks and soil from the red planet. The plan was for NASA to send a robotic spacecraft to Mars to bring those samples back to Earth, but the agency has now scrapped those plans thanks to a ballooning price tag and extensive delays. With no way of getting to Mars on its own, NASA is hoping to hitch a ride with private space companies to finish the mission. Marketplace’s Lily Jamali spoke to Kenneth Chang, science reporter at The New York Times, about NASA’s difficulties on Mars and its partnerships with the private sector.
