The latest surge of COVID infections has hospitals crowded, short-staffed and, in some cases, rationing care. That means sometimes hospital clinicians have to go through a triage process to prioritize who gets care first, or at all. For example, a doctor may decide that a patient suffering respiratory failure should be admitted to the intensive-care unit over someone who seems to have minor injuries from a car accident. But that distinction, especially in a crisis, might not be so clear-cut. So medical research centers like Johns Hopkins and Stanford are studying how machine learning might help. Marketplace’s Kimberly Adams speaks with Dr. Ron Li, a clinical assistant professor at Stanford Medicine, where he’s medical informatics director for digital health and artificial intelligence clinical integration.

Sure, CES had the snazziest new wearables and fitness gear, but the show this year also debuted new advancements in what’s known as “femtech.” This is technology targeted at health issues affecting cisgender women, as well as some intersex and transgender people. It’s an area with historic underinvestment, but that may be changing. Marketplace’s Kimberly Adams speaks with Monique Mrazek, a senior global health tech industry specialist for the International Finance Corp., which is part of the World Bank Group. She asked Mrazek what femtech encompasses.

The Consumer Electronics Show just wrapped in Las Vegas. This year, it was a hybrid conference due to the recent surge in COVID-19 cases. Some attended in-person exhibits and talks, while others tuned in remotely. One of the remote attendees this year was Brian Cooley, an editor at large for CNET. Marketplace’s Kimberly Adams checked in with him about what new tech is getting all the buzz, and what it’s like attending the biggest tech show on Earth from home.

In the aftermath of the Jan. 6 insurrection, public pressure forced social media companies to increase moderation of misinformation and hate speech. In the process, many users and groups were banned from mainstream sites. So those users, and some of their audience, are moving to alternative social media sites and apps. Jared Holt is a resident fellow at the Atlantic Council, a think tank based in Washington D.C. He says these alternative spaces have seen noticeable growth.

In the weeks after the Jan. 6 insurrection, law enforcement agencies and internet sleuths identified hundreds of people who stormed the U.S. Capitol. Many were later arrested or faced consequences at their jobs or in their communities. Authorities used a variety of technologies to speed up that process, which was needed because there were millions of images, messages, social media posts and bits of location data to parse. Marketplace’s Kimberly Adams speaks with Anjana Susarla, professor of responsible artificial intelligence and information systems at Michigan State University.

This week, a jury found Elizabeth Holmes, who created the defunct diagnostics company Theranos, guilty of defrauding investors. While running the company, she claimed Theranos had proprietary technology that could test someone for a variety of ailments using just a drop of blood. That wasn’t true. So what does the jury’s decision mean for the future of investing in biotech startups? Elizabeth Lopatto is deputy editor at The Verge and covered the trial closely for several months. She said that a major theme during the trial was how Holmes spoke with investors.

One of the tech buzzwords in this new year is metaverse. And even though lots of tech companies are promising we’ll soon have an immersive experience where you can stream your favorite show or host a virtual work meeting, there is still a way to go before we get there. And one of the issues to be sorted out first — hopefully — is how user privacy works in a world build on augmented and virtual reality. Marketplace’s Kimberly Adams speaks with Jessica Lee, a partner at the law firm Loeb & Loeb, who advises companies on user privacy.

New technology has shaped so much of the last year, including advancements in biotech and better software helped many of us work and learn from home more efficiently. So what’s ahead for tech in 2022? Marketplace’s Kimberly Adams speaks with Amy Webb, a futurist and founder of the Future Today Institute. Webb says 2021 gave us a lot of signals about what’s coming next.

Early in the pandemic, Sidewalk Labs — an offshoot of Google — announced it was shutting down a big project in Toronto called Quayside. It was meant to be a testing ground for smart-city concepts, a hyperconnected neighborhood from the ground up, with things like an underground network of package-delivery robots. But even before the pandemic, it ran into the same problems that have dogged smart-city projects around the world. Marketplace’s Meghan McCarty Carino speaks with Shannon Mattern, who focuses on this topic in her new book, “A City Is Not a Computer: Other Urban Intelligences.” Mattern said optimizing cities for connectivity often means giving up privacy.

Let’s talk about gardening technology. Not some fancy gadget for monitoring water or sunlight, but technology that feeds the dirt itself. Washington, D.C.’s wastewater-treatment plant is one of the largest high-tech plants in the world. It uses a process akin to pressure cooking to turn what’s flushed down the toilet into fertilizer fit for planters at home. Marketplace’s Kimberly Adams takes a tour to learn more about thermal hydrolysis tech.
