Imagine you’re a national security official tasked with monitoring activity off the coast of your fictitious country. Suddenly, a large tanker ship in your area goes silent. Its location sensor is offline, and it’s not responding to radio communication. What do you do? It’s a question Francesca de Rosa, chief scientist for gaming at the Center for Advanced Preparedness and Threat Response Simulation, poses in the Reliability Game, which she designed. It’s part of a genre known as “serious games.” De Rosa told Marketplace’s Lily Jamali that while serious games can be fun, they’re really meant to prepare people to handle all kinds of situations.

A new wearable from tech startup Humane promises to bring an AI assistant to your lapel. It attaches to your jacket, sweater or shirt and operates with voice commands or a digital interface laser projected onto the palm of your hand. It sounds like the stuff of a sci-fi novel, but the reviews so far are not good. The panning of the Ai Pin comes after five years in development, $240 million in funding and partnerships struck with the likes of OpenAI, Microsoft and Salesforce. So, what went wrong? Marketplace’s Meghan McCarty Carino asked Victoria Song, senior reviewer at The Verge, what this device is supposed to be for.

Artificial intelligence has become a big part of medicine — reading images, formulating treatment plans and developing drugs. But a recent investigation by Stat News found that some insurers overrely on an algorithm to make coverage decisions for seniors on Medicare Advantage, a Medicare plan offered by private insurers. Marketplace’s Meghan McCarty Carino spoke with Casey Ross, who co-reported the story. He said an algorithm predicted how long patients needed care and coverage was curtailed to fit that calculation.

On this week’s show, the United Kingdom is cracking down on makers of sexually explicit deepfakes. We’ll look at what penalizing the practice could mean for the victims. Then, the creator economy has the attention of millions of subscribers, but also venture capital. Why content creators like Dude Perfect on YouTube and other startups are attracting so much investment right now. But we begin with Amazon. The e-commerce giant’s Just Walk Out technology lets shoppers scan an app when they enter a store so they can leave with their purchases without paying at a register. This week, Amazon said there’s growing interest in the technology among retailers outside its empire. Yet the company is reportedly reducing the use of Just Walk Out in its own brick-and-mortar stores. Marketplace’s Lily Jamali spoke with Natasha Mascarenhas, reporter at The Information, for her take on these stories.

When you think about gin, what tastes comes to mind? Pine? Maybe citrus or coriander? It can vary quite a bit because unlike some spirits, gin is very lightly regulated. Distillers can throw in all kinds of flavors and call the result “gin” as long it has some minimum requirements. In the U.S., gin is gin as long as the flavor is derived from juniper berries and alcohol by volume is at least 40%. In the European Union, the minimum ABV is 37.5%. But researchers in Edinburgh, Scotland, recently identified the exact elements that define gin using nuclear magnetic resonance spectroscropy. Think of it as something like an MRI scan that lets scientists create a flavor “fingerprint.” The new technique could have big implications for this very old industry. Marketplace’s Lily Jamali spoke with Eve Thomas, who wrote about it for Wired, to learn more.

When the chemical company DuPont unveiled Teflon in 1946, nonstick pots and pans seemed like a miracle. We now know their coatings contain “forever chemicals,” or PFAS, which don’t break down. These compounds are not only in cookware but in clothing, cosmetics and more — and they contaminate the water millions of us drink. Research shows there’s no safe level of exposure. As the EPA rolls out new limits on PFAS in drinking water, Marketplace’s Lily Jamali asked Tasha Stoiber, senior scientist at the Environmental Working Group, about the tech used to filter it.

President Joe Biden won Arizona in 2020 by a razor-thin margin, flipping the state blue for the first time in more than 20 years. As a result, Arizona became a hotbed of election misinformation and conspiracy theories, as false claims of a stolen election led to protests outside voting centers, a GOP-backed ballot audit and threats against election workers. Now, with just over 200 days until the 2024 election, experts warn that artificial intelligence could supercharge misinformation and disinformation in this year’s race. So how are election officials in a state that has already been in the trenches preparing for another battle over facts? In this episode of “Marketplace Tech’s” limited series, “Decoding Democracy,” Lily Jamali and Kimberly Adams look back at what happened in Arizona during the last presidential election and how the state became entangled in conspiracy theories. Plus, we hear from Arizona Secretary of State Adrian Fontes about how his office plans to combat AI-charged misinformation this year.

The programming language known as COBOL turns 65 this year. We couldn’t help noticing that’s right around retirement age, but COBOL is nowhere near retirement. It remains a mainstay of IT operations at U.S. government agencies, businesses and financial institutions. Yet the programming language, which is older than the Beatles, is no longer taught at most universities. Glenn Fleishman is a freelance tech journalist who has written about this aging slab of digital infrastructure. Marketplace’s Lily Jamali asked him whether our continuing reliance on COBOL is a problem.

The Labor Department this week confirmed what a lot of Americans have been feeling: Inflation is kind of sticking around, and higher interest rates are likely to as well. We’ll look at what that means for venture capital, which was already slow to flow. Plus, the Joe Biden administration announced a $6.6 billion deal with Taiwan-based semiconductor maker TSMC to build a third production hub in Arizona. We take a look at the ongoing rollout of the CHIPS and Science Act, which makes it all possible. But first, Tesla has settled a lawsuit in the death of a software engineer who was killed driving a Tesla while using the company’s semiautonomous driving software, Autopilot. The suit put scrutiny on Elon Musk’s claims about the software.

Marketplace’s Lily Jamali is joined by Jewel Burks Solomon, managing director at Collab Capital, for her take on these stories.

More than 99% of all species that have lived on Earth are now extinct — something humans have certainly had a hand in. There’s now an entire scientific discipline devoted to bringing some of these species back. If you’re picturing those cloning scenes from “Jurassic Park” right now, we get it. But “de-extinction” is not quite that. Beth Shapiro is the chief science officer at Colossal Biosciences, a bioengineering startup working on de-extinction. She explained to Marketplace’s Lily Jamali how the process works.
