As recently as August, Airbnb was doing brisk business in New York City, with more than 22,000 listings there. Two months and a citywide crackdown later, that number has fallen to just above 3,000, a decrease of more than 80%. Local Law 18, which took effect last month, requires hosts of short-term rentals on Airbnb, Vrbo and similar sites to register with the city and live in the property they’re renting out. Marketplace’s Lily Jamali spoke with Amanda Hoover, a staff writer at Wired, who’s been following the fallout from the new law.

The technology known as CRISPR is considered one of modern biology’s biggest breakthroughs. It allows scientists to edit genes, similar to how you cut and paste text in a word processor. More than a decade after pioneering CRISPR, Nobel laureate Jennifer Doudna of the University of California, Berkeley, is applying it to big problems, like chronic disease and climate change.Marketplace’s Lily Jamali recently met up with Doudna at Berkeley’s Innovative Genomics Institute. It’s a cluster of lab stations, researchers and very loud refrigerators where CRISPR is used to edit microbiomes.

Thousands of Israelis and Palestinians have lost their lives since Hamas gunmen staged their surprise raid on Oct. 7. In the wake of the attack, Israel’s defense forces have called up more than 350,000 reservists, about 4% of its population. The country’s booming tech industry could be affected more than most, given that so many younger Israelis work in the sector. Fast Company contributing writer Issie Lapowsky recently interviewed several of them, including an Israeli tech lawyer named Yitzy Hammer.

The talk of late at the Federal Communications Commission is whether to restore net neutrality. When the Barack Obama administration put those rules in place in 2015, the idea was to ensure that internet service providers — or ISPs — like Verizon and Comcast gave consumers fair access to the web and didn’t favor sites and services they controlled. But that mandate was repealed two years later under then-FCC Chair Ajit Pai, chosen by then-President Donald Trump. He argued that net neutrality would disincentivize companies from building their networks in low-income, urban and rural areas. Critics of the repeal argued that rural America’s ability to access the internet would be hurt. After the federal repeal, some states adopted their own net neutrality regulations while others didn’t, which provided a pretty great data set for researchers wanting to know: What would getting rid of net neutrality mean for internet access in rural areas? 

The word “bacteria” doesn’t exactly evoke positive images, but scientists at Cornell University recently discovered a novel way to replicate and use a bacterium from Oneida Lake in New York state. It’s called Shewanella oneidensis, and it has a special affinity for the rare-earth elements — such as so-called lanthanides, metals that are important for clean, renewable energy technology. The bacteria can be used to process rare-earth metals through a method called biosorption, which is considered safer and less taxing on the environment than current means of extraction. Marketplace’s Lily Jamali discussed the findings with Buz Barstow, a professor of biological and environmental engineering at Cornell and a lead researcher on the project.

If you asked for an extension on last year’s taxes, the bad news is the filing deadline was yesterday. The good is if you got it in, refunds are expected to reach you faster than they have in recent years. The notoriously clunky technology behind the IRS is getting a massive update, thanks to a $60 billion cash infusion from last year’s Inflation Reduction Act. The IRS’ technology was considered cutting edge in the 1960s, but Erica Neuman, assistant professor of accounting at the University of Dayton, tells Marketplace’s Lily Jamali the IRS needs all the IT help it can get.

When you think of the early days of video games, the Fairchild Channel F console might not be the first brand that comes to mind. The Fairchild Channel F was released in 1976, before the more famous Atari released its console. It was also the first system to use individual game cartridges, thanks in large part to Jerry Lawson, a Black engineer at Fairchild. Marketplace’s Meghan McCarty Carino recently spoke with Anthony Frasier, CEO of ABF Creative and host of a podcast about Jerry Lawson called “Raising the Game,” about Lawson’s life and achievements.

Chinese automaker BYD is now the most popular EV in China and could soon beat Tesla as the No. 1 EV globally. As the Chinese auto market moves to electric, the playing field is getting crowded.

Whether it’s for travel, meals or event tickets, it’s hard to deny the allure of a good deal. And providing discounts through fraudulent means is a thriving business online. Once mostly relegated to the far reaches of the dark web, fraudsters are offering questionable deals to consumers on mainstream social media sites and messaging apps. That’s according to the online fraud prevention company Sift. Part of the scam is what is called an account takeover or ATO. Marketplace’s Lily Jamali spoke with Brittany Allen, a trust and safety architect with Sift, about why ATOs are increasing.

They say it’s harder to get into than Harvard: Y Combinator, YC for short, is “startup school” for tech founders. It takes applications twice a year. Being among the 230 startups accepted out of 24,000 means getting a half-million-dollar investment and access to mentors who’ve already made it. Airbnb, Reddit and DoorDash are on the alumni list. For most of its 18-year history, Y Combinator has been based in Mountain View, California, the heart of Silicon Valley. Recently, though, its center of gravity has moved about 40 miles north to San Francisco. YC opened a new office in June and now considers the city its headquarters. Garry Tan took over last year in a role once held by OpenAI CEO Sam Altman. Tan wants founders to be nearby, at least during the first three months they’re in the program. He told Marketplace’s Lily Jamali why during a walk through the city.
