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.

The network of online communities known as Reddit has millions of weekly active users. They post on “subreddit” forums like r/WhatShouldICook — a place where people just talk about their dinner plans — and r/ShowerThoughts, where participants share what they’re thinking during routine tasks. The co-founder and CEO of Reddit, Steve Huffman, is a fan of r/Daddit, being a father himself. Marketplace’s Lily Jamali spoke with Huffman at Reddit headquarters in San Francisco, where they talked about the company selling stock and its recent licensing agreements with the likes of Google and Open AI, which use Reddit content to train their large language models.

It’s cornered the market for boomers. Now, Mark Zuckerberg’s Meta hopes to make Facebook once again a favorite social media app for young adults. Plus, the Wall Street Journal reports E*Trade is considering whether to give the boot to user Roaring Kitty, who helped ignite the 2021 meme stock craze. In case you missed it, yes, the craze is back. But first, there’s yet another open letter on AI. This whistleblower letter comes from more than a dozen current and former employees at major AI companies. They warn of the risks posed by the technology being developed. Marketplace’s Lily Jamali is joined by Natasha Mascarenhas, reporter at The Information, for her take on this week’s tech news.

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.
