Peptides are short chains of amino acids. GLP-1 weight loss drugs are peptides. Insulin is one, too. And there are thousands of others. Now, people are seeking out peptides in the hope of better muscles, better skin, better memory, better…everything. Many of the peptides people wanna try are available for research use only but the Food and Drug Administration might change this. In July, the agency could decide to make about a dozen peptides more accessible by allowing pharmacies to compound and distribute them Marketplace’s Stephanie Hughes spoke with Zara Stone, tech culture reporter at The San Francisco Standard, to learn more.

The wildfire risk mitigation company Technosylva helps utilities, insurers and government agencies predict where and when a fire could spark. It uses historical weather data to make those predictions and suggest changes to help prevent or mitigate a fire. For example, maybe moving a tree branch that's close to a power line so it doesn't fall and start a fire. The company is nearly 30 years old, and Technosylva's chief executive, Bryan Spear, explains how the advent of AI has changed the work they do.

On this week’s Marketplace Tech Bytes: Week in Review, we take a look at how college graduates do not wanna hear about AI. Plus, what we all learned from the Musk v. Open AI case. But first, AI was unsurprisingly front and center at Google’s annual I/O developer conference. Among a suite of new AI products, Google said it updated its iconic search bar. Now, when searching in AI mode, the bar will expand as you ask a question. It will also provide suggestions about what you might wanna ask. Google says this is the biggest change to its search box since it debuted over 25 years ago. Marketplace’s Stephanie Hughes spoke with Anita Ramaswamy, a columnist at The Information, about how this could change how people experience the internet.

Anthropic’s newest AI model, Mythos, is so good, the company says, at uncovering security vulnerabilities that it's too dangerous to release to the public. Anthropic shared a preview version with a select group to help patch the holes that Mythos finds. But the prospect of a super-hacker AI system is still sending some business leaders into a panic. Marketplace’s Meghan McCarty Carino reports.

Earlier this month, a group called ShinyHunters took responsibility for a hack on the education platform Canvas, which is used for coursework at colleges. In a letter posted online, the group threatened to leak data it took from the platform, including billions of private messages between students and teachers. Canvas was also temporarily unavailable, disrupting students’ ability to do their work. Then, last week, Instructure, which makes Canvas, said it had reached a deal with the hackers, that the data had been returned and all copies destroyed. Marketplace’s Stephanie Hughes asked Rachel Tobac, CEO at Social Proof Security, what we know about the deal.

As of mid-2025, about a third of newly published websites were generated by artificial intelligence. That’s a massive increase from just three years before when the number hovered around zero. The AI written text provides fewer diverse viewpoints and is generally presented in a cheerful manner. That's all according to an early study out last month. Marketplace’s Stephanie Hughes spoke with one of the study’s authors, Stanford University researcher Maty Bohacek, about how AI is changing the nature of the internet.

Hydropower is one of the oldest forms of energy creation, and uses the flow of rushing water to create electricity. The province of Québec, Canada, has historically had an abundance of it and, later this spring, will start supplying hydropower to New York City. This is the second big hydropower line to link Québec and the Northeast U.S. this year, after a line to Massachusetts came on board this winter. Right now, the power is going one way, from Canada to the U.S., but some are thinking that the U.S. could eventually sell renewable wind energy back to Canada and let that country hold on to its hydropower for when it's really needed, creating a “regional battery,” says Marketplace's Henry Epp, who’s been reporting on this.

This week, WhatsApp is offering private chats with its AI. Plus, Princeton will now hold supervised exams after a rise in AI-fueled cheating. But first, Google’s self-driving car division Waymo opted to do a voluntary recall of 3,800 of its robotaxis. This comes after a Waymo drove into a flooded road in San Antonio, Texas. The car was empty and no one was hurt, but Waymo is now updating its software to address how its cars deal with flooded roads. Will Oremus at The Atlantic joins Marketplace’s Stephanie Hughes for these stories. Check out our YouTube page to watch more episodes of “Tech Bytes.”

Voice cloning is the use of artificial intelligence to generate a clone of a real person’s voice, imitating the sound, when they pause and what words they typically emphasize. And it can be hard for people to identify voices as being AI-generated. Research last year from UC Berkeley professor Hany Farid, an expert in digital forensics, found that people correctly identify a voice as AI-generated only 60% of the time. Marketplace’s Stephanie Hughes spoke with Farid about the rapid sophistication of audio deepfakes, why it's so hard to tell the difference between a real voice and an AI-generated one right now, and some tips to help you spot voice clones.

In order to write her new book “I Am Not a Robot: My Year Using AI To Do ‘Almost’ Everything," journalist Joanna Stern decided to invite artificial intelligence into every aspect of her life — including her family life. She has a wife and two sons. On their spring break, she took them to Phoenix, where it's easy to hail a driverless car. They rode in a bunch of them, including one that totally freaked out. She brought home an AI-powered toy (which her four-year-old quickly tired of), and says she realized her kids will "grow up never knowing a world without computers as smart as them.” Marketplace’s Stephanie Hughes spoke with Stern about how she hopes her children will navigate that world.

Imagine if you invited robots - smart ones or “smart-ish,” at least - into every aspect of your life. Your emails and texts are all composed by an AI, the bots look at a photo of what’s in your fridge and figure out what you can make for dinner. They even become emotional support, providing advice and sometimes companionship. Journalist and founder of media company New Things, Joanna Stern, decided to try this and she wrote about it in her new book “I Am Not a Robot: My Year Using AI To Do Almost Everything.” Marketplace’s Stephanie Hughes spoke with Stern about how AI did and didn’t help her and ultimately what she sacrificed by inviting AI into her life.

There's a new flex in Silicon Valley: how big is your AI agent swarm? They can work on your behalf, autonomously, 24/7, on whatever goal you give them. You might think having an army of AI minions could free up some time, maybe make work more chill. But, you’d be wrong, as Marketplace’s Meghan McCarty Carino reports.

On this week’s “Marketplace Tech Bytes: Week in Review,” we’ll discuss why Apple is paying a $250 million settlement over its Apple Intelligence tool and its capabilities. Plus, GameStop makes a surprising buyout offer for eBay. But first up: Anthropic, maker of the chatbot Claude, announced a new computing deal this week with SpaceX and its AI division, xAI. Anthropic will get access to SpaceX’s Colossus One data center, which will let the company increase how much its customers can use Claude. The deal comes as SpaceX CEO Elon Musk is facing off in federal court against OpenAI and its CEO Sam Altman. Marketplace’s Stephanie Hughes spoke about all this with Caroline O’Donovan, AI and technology senior reporter at The San Francisco Standard, who noted that Anthropic's leaders talked about the need for more computing power at their developer conference this week. Check out our YouTube page to watch more episodes of “Tech Bytes.”

Back in 2015, Elon Musk and Sam Altman got the idea to start a nonprofit AI lab to develop artificial general intelligence that benefits all humanity. The lab would also make its technology open source, calling it OpenAI. All that is according to a complaint filed by Elon Musk, who has since parted ways with the organization. And now he is suing OpenAI, its CEO Sam Altman and its president Greg Brockman, saying they have abandoned the founding principles of the organization in pursuit of profits. They are currently facing off in federal court in the Northern District of California. Paresh Dave at Wired has been in the courtroom. He explains more on what the core of Musk's case is.

Technology has been transformative for how police officers do their jobs. Body cameras, speed detection technology and surveillance drones are some prominent examples. And now, law enforcement departments are trying to figure out if and how they want to add artificial intelligence to the mix. Marketplace’s Stephanie Hughes spoke with Greg Barber, a science and technology journalist who recently wrote about this for Proof News. He explained how AI is being used in police work now and whether or not AI has become a time-saving tool for officers.

The startup Winnie is a marketplace for childcare. It works like this: Parents type in the age of their kid and their zip code, then different childcare providers in the area will pop up. You can also filter by languages spoken, and whether you want a childcare center or home-based daycare or another option. It's free for parents to use. But the company was founded back in 2016, when AI search wasn’t really a thing. And Winnie’s CEO and co-founder Sara Mauskopf says parents now want to be able to describe what they're looking for in natural language. So, Winnie has had to adapt. It's just released an AI-powered search tool. Marketplace’s Stephanie Hughes spoke with Mauskopf to learn more about their new AI search engine and the challenges of keeping up with the fast-paced AI sector.

The GUARD Act is a bipartisan bill that would prohibit companies from letting kids under 18 interact with what the legislation calls "AI companions,” which are chatbots designed to encourage the simulation of an interpersonal relationship. This comes after some harrowing stories of teenagers who developed relationships with chatbots and then harmed themselves or others. The bill just passed out of the Senate Judiciary Committee. Marketplace’s Stephanie Hughes talks about this with Ashley Gold, a senior tech policy reporter at Axios.

This week, Taylor Swift trademarked her voice and image in what appears to be a bid to protect against AI misuse. Plus, a Japanese airline is experimenting with humanoid robots to help with baggage. But first, Google landed a deal with the Pentagon to let its AI models be used for classified work. A Google spokesperson told us in a statement that the company is proud to be providing its services for national security and that it believes AI should not be used for “domestic mass surveillance or autonomous weaponry without appropriate human oversight." We talked with Maria Curi at Axios about how Google’s deal compares to ones the Department of Defense has with other AI companies. Check out our YouTube page to watch more episodes of “Tech Bytes.”

The war with Iran has upended supply chains including for materials that are critical to building the electronics we use everyday, such as a certain kind of thermoplastic, copper, and helium. We are now dealing with shortages of all of them. Marketplace’s Stephanie Hughes spoke with Jeff Janukowicz, an analyst with the research firm IDC, to learn more.

There's been renewed interest in nuclear power in recent years, thanks in part to demand from tech companies in search of reliable energy to power their AI data centers. The startup Kairos Power has jumped on this opportunity. Its nuclear reactors are cooled by molten salt. They also use golf-ball sized nuclear fuel, instead of uranium rods cooled by water used by traditional reactors. Mike Laufer, co-founder and CEO of Kairos, says their reactors a bit like an upside down gumball machine. The company just started construction on its first power plant, located in eastern Tennessee, called Hermes 2. It will supply energy to the utility in the area, the Tennessee Valley Authority, and specifically to Google to power its data centers. Marketplace’s Stephanie Hughes spoke with Laufer to learn more.
