TikTok is going to be testing a new crowd-sourced fact-checking system called Footnotes. It’s seems similar to the Community Notes systems already in use on other social media, such as X and Facebook.

TikTok is also keeping its current fact-checking systems in place. The way these community systems generally work is, say someone makes a post stating "whales are the biggest fish out there." Another user could add a note saying "actually, whales are mammals, and here's a source with more information."

Marketplace’s Stephanie Hughes spoke with Vanderbilt psychology professor Lisa Fazio about why this model of "citizen fact-checking" is catching on.

The use of algorithmic software in setting residential rents has come under scrutiny in recent years. In 2024, the Joe Biden administration sued real estate company RealPage, alleging that its algorithm, which aggregates and analyzes private data on the housing market, enables landlords to collude in pricing and stifles competition. There's no word yet on what the second Donald Trump administration's Justice Department will do with this case. But in the meantime, some cities are banning the use of these algorithms completely. Marketplace’s Meghan McCarty Carino spoke with Robbie Sequeira, who has been reporting on the issue for Stateline.

We've sometimes wished we could have our own Wendy Rhodes, the performance coach at the hedge fund on the TV show “Billions.” Most workplaces, however, aren't bringing in billions and can't afford a Wendy. But an upskilling platform called Multiverse uses artificial intelligence to provide personalized, on-the-job guidance. Its AI coach, Atlas, helps workers expand their abilities and keep themselves relevant in an economy that makes skills obsolete faster than ever before, says Ujjwal Singh, chief product and technology officer at Multiverse.

Developers of mobile apps have "room for improvement" in making their platforms fully accessible for disabled users, according to a new report from the software company ArcTouch and the digital research platform Fable.

It looked at fifty popular apps and assessed them for features that improve accessibility like screen reading, text size adjustability, voice controls and multiple screen orientations. The apps were tested by disabled users who reported a poor or failing experience almost three-quarters of the time.

Marketplace’s Meghan McCarty Carino spoke with Ben Ogilvie, head of accessibility at ArcTouch, to learn more about why so many apps are behind.

NVIDIA gets caught up in the trade war, the titans of Twitter/X debate intellectual property law — and the Federal Trade Commission's antitrust case against Meta kicks off in court.

We're digging into all of it on today's Tech Bytes: Week in Review. Marketplace’s Meghan McCarty Carino speaks with Anita Ramaswamy, columnist at The Information, about what we learned in week one of Meta's monopoly trial.

Flying cars have been a staple of science-fiction visions of the future for ages. Perhaps most famously in “Back to the Future II.” The film may have overshot the mark a bit with Doc and Marty McFly navigating full-on air highways in 2015. But Utah is pushing for the technology to take off by 2034, when the state hosts the Olympic and paralympic winter games.

We're not exactly talking about flying Delorians or vehicles you'd recognize as a car, but rather small, lightweight aircraft for traveling shorter distances. Reporter Caroline Ballard got a first look at the air taxis.

China is responsible for most of the world’s processing of rare earth metals and minerals, but its new export restrictions have raised the stakes for U.S. efforts to build its own supply chain and processing industry. Barbara Arnold, a professor of mining engineering at Penn State, says there are options, but they require time, development and investment.

Surveillance technology like automated license plate readers has become commonplace in policing. They've made it easier to locate stolen vehicles and track suspects, but they've also raised concerns about civil liberties. Cardinal News Executive Editor Jeff Schwaner took a 300-mile drive through the state to see how often his car would be recorded. Marketplace’s Meghan McCarty Carino spoke with Schwaner about his experience and issues related to privacy and who has access to the data.

One area where artificial intelligence has been swiftly adopted is software coding. Google even boasted last year that more than a quarter of its code was generated by AI. But the technology is also generating challenges to the traditional technical job interview, where candidates are given programming problems as a way to assess their skills. And lately it’s become apparent that a lot of applicants are using AI to give themselves a boost, according to recent reporting from Business Insider's Amanda Hoover. Marketplace’s Meghan McCarty Carino spoke with Hoover about the controversy over applicants using AI while interviewing for jobs that often use AI.
