Accessibility has long been aided by the advancement of technology. When it comes to artificial intelligence, accessibility is top of mind for Taylor Arndt, Chief Operations Officer at Techopolis Online Solutions. Arndt has been blind since birth, and so accessibility has been a lifelong battle. When she was in school, she often received physical materials she was unable to read. So, she bought her own hand-held scanner and downloaded a screen reader. At 14, Arndt taught herself to code. Now as a coder working on AI, Arndt says in order for it to help others, the AI models need to be trained on data that has already incorporated accessibility measures.

Sub-Saharan Africa has a youth unemployment problem. The latest figures from the International Labour Organisation show more than one in five young people there are "NEET": Not in Employment, Education or Training. Structural issues like the lack of political stability in many countries and lagging infrastructure remain major barriers to high quality job creation. But the gig economy has been growing rapidly thanks to the proliferation of digital platforms. The The BBC's Wairimu Gitani reports.

Hannah Quay-de la Vallee, senior technologist at the Center for Democracy and Technology, coauthored a recent report that recommends more transparency on what artificial intelligence education technologies can and cannot do.

In the Trump administration's efforts to shrink and realign the federal government, datasets on climate, health and demographics have disappeared. Some have been scrubbed from public view, others may not be collected anymore.

This data supported apps and interactive tools many researchers relied upon.

Marketplace’s Meghan McCarty Carino spoke with Denice Ross, senior advisor with the Federation of American Scientists and former chief data scientist for the U.S., who recently wrote a tribute to the data that's been lost.

Dr. Carlos Chaccour, physician scientist at the University of Navarra, noticed something fishy about a letter to the editor the New England Journal of Medicine received shortly after it published a paper of his on malaria treatment in July.

The letter was riddled with strange errors such as critiques supposedly based on other research Chaccour himself had written. So he and his co-author Matthew Rudd decided to dig deeper.

They analyzed patterns of letters to the editor over the last decade and found a remarkable increase in what they call "prolific debutantes" — new authors who suddenly had dozens, even hundreds of letters published, starting right around the time OpenAI’s ChatGPT came out.

Why would academics want to do this? Marketplace’s Meghan McCarty Carino spoke with Chaccour to find out.

The holiday shopping season is here, and AI companies are pushing new chatbot retail partnerships. But, can these tools deliver on their promises to make shopping easier? Plus, the return of Vine, the beloved video app known for its ultra-short absurdist memes.

But first, Meta is not a monopoly, according to a federal judge’s ruling this week in the longstanding antitrust case against the social media giant, which claimed Meta had stifled competition by buying Instagram and WhatsApp.

Marketplace’s Meghan McCarty Carino spoke with Paresh Dave, senior writer at Wired, to discuss all of the above on this week’s “Marketplace Tech Bytes: Week in Review.”

Grokipedia, the AI-powered encyclopedia launched by Elon Musk's xAI last month, promises to be an ideological alternative to Wikipedia. But the tool doesn't just have a different political flavor, argues Ryan McGrady, senior fellow at the Initiative for Digital Public Infrastructure at the University of Massachusetts Amherst.

He recently wrote, for Tech Policy Press, that Grokipedia takes a more top-down approach to knowledge, one that harks back to less democratized eras.

China recently came out with its latest five-year plan for growth, which will guide the world’s second largest economy through 2030. In it, top Communist Party leaders have pushed to boost the country's strength in manufacturing to the next level by upgrading older factories with advanced technologies for automation.

The challenge, according to the Chinese ministry of education, is that the sector has tens of millions of open jobs because there aren't enough skilled workers in the labor force to fill them.

One school is trying to bridge that gap. Marketplace China correspondent Jennifer Pak visited it in Nanjing city.

One thing almost everyone can agree on about Zohran Mamdani, mayor-elect of New York City: he's very good at vertical short-form video.

Love it or hate it, the format has a stylistic language all its own. So, we asked Joshua Scacco, professor of communications and director of the Center for Sustainable Democracy at the University of South Florida, to help us dissect what exactly makes a political short form video effective.

About a third of global greenhouse gas emissions come from our food systems, and livestock production is a big part of that. Experts largely agree that one of the biggest actions individuals can take to lower emissions is to eat less meat.

But that's a hard sell for a lot of consumers. Americans have actually been eating more meat in recent years, and sales of plant-based meat alternatives have dropped.

There are a lot of companies out there trying to innovate climate-friendly meat and alternatives for the future.

For our podcast "How We Survive," Marketplace's Amy Scott visits a lab at Columbia University where researchers are figuring out how to make a more convincing and enjoyable fake meat.
