What if receiving a medical diagnosis was as simple as shopping online? The growing home diagnostics industry says it can be. At-home testing was widespread during the COVID-19 pandemic, but more health tech companies also offer DIY kits that test for food allergies, fertility and thyroid function, among other things. Some medical experts are wary of this on-demand model, but health tech investors say it can make health care more accessible. Marketplace’s Lily Jamali spoke to Chrissy Farr, author of the Second Opinion newsletter, and Anarghya Vardhana, a partner at the Maveron venture firm, about the prospects of the industry and how it affects relationships between patients and doctors.

Last Friday felt like something out of a Y2K nightmare after the cybersecurity company CrowdStrike, pushed a software update to all its clients — including health care systems, banks and the federal government — that ended up crashing computer systems worldwide. The fallout is still being felt, particularly in the travel sector, as airliners try to reschedule canceled flights while trying to get everything back to normal. It’s also become something of a reminder that the internet and a lot of the online services we rely on are delicate. Marketplace’s Lily Jamali spoke with Kate Conger, a reporter at The New York Times who recently wrote about this with her colleague David Streitfeld.

Online sales in the U.S. surpassed $14 billion during Amazon Prime Day last week, according to Adobe Analytics. Amazon’s heft and promotional power continue to drive sales, even for rivals, during the shopping jamboree. But in Europe, an important market for the e-commerce giant, lawmakers have become increasingly sensitive to Amazon’s relations with its rivals, as well as its partners and customers. They’ve requested that Amazon hand over information about its product recommendation algorithms, along with data on ads, by Friday. It’s part of compliance with the European Union’s Digital Services Act, a sweeping set of tech regulations that took effect in recent years. Marketplace’s Meghan McCarty Carino discussed it with Theo Wayt, who covers Amazon for The Information.

A new Senate report finds Amazon Prime Day is prime time for warehouse injuries. Plus, Starbucks is teaming up with Mercedes-Benz to supercharge electric vehicle infrastructure. But first, several Silicon Valley billionaires have thrown their support behind former President Donald Trump in his quest to reclaim the White House, thanks in part to his pick for vice president, Sen. J.D. Vance. Marketplace’s Meghan McCarty Carino spoke with Jewel Burks Solomon, a managing partner at Collab Capital, for her take on these stories in Marketplace Tech Bytes: Week in Review.

FBI officials are still looking into what motivated the 20-year-old gunman who attempted to assassinate former President Donald Trump on Saturday. As of this episode, investigators have yet to publicly share any conclusions about his reasons for the attack, which killed a rally attendee and injured the former president and two others. But the lack of information didn’t stop misinformation from flooding online channels. Marketplace’s senior Washington correspondent, Kimberly Adams, speaks with Molly Dwyer, director of insights at PeakMetrics, and Lisa Fazio, associate professor of psychology at Vanderbilt University, about the false narratives surrounding the shooting and how to separate fact from fiction in the aftermath of a violent event.

Pop quiz: What’s a policy supported by political rivals in California and Florida? The answer is banning cellphones in school. Florida is among a handful of states that have restricted mobile devices in the classroom. California has not, though Gov. Gavin Newsom has pushed the Legislature to act. The policies are intended to reduce distraction and mitigate addiction and other mental health concerns attributed to phone use. But Liz Kolb, a clinical professor of education at the University of Michigan, tells Marketplace’s Meghan McCarty Carino it’s not that simple.

In recent years, we’ve seen a surge of state laws and policies affecting trans people. Half of states have banned or restricted gender affirming care for minors, with some adding restrictions for adults. The ACLU is tracking more than 500 bills that have been introduced across the country. The enforcement of such laws, as with recent bans on abortion and related reproductive care, have raised concerns about tracking people’s digital footprints. So much of daily life is conducted online, and there are currently no federal data privacy protections. KB Brookins, a writer based in Austin, Texas, wrote about a personal experience that drove home concerns about their trail of digital data.

Sandwiched between some blockbuster Supreme Court rulings last month came a decision — or more so, a non-decision — that is reverberating through the tech world. NetChoice, big tech’s lobbying arm, challenged a pair of laws in Florida and Texas that sought to restrict how social media platforms moderate content. The high court kicked both cases back to lower courts with some added commentary. Marketplace’s Meghan McCarty Carino spoke with Lauren Feiner, senior policy reporter with the Verge, who wrote about what this means for future attempts to regulate tech.

The Republican Party officially adopted former President Donald Trump’s 2024 platform this week. The GOP is now taking a friendly approach to cryptocurrency and artificial intelligence, with plans to roll back regulation of both. Plus, Meta’s Threads platform celebrates its one-year anniversary this month. But first, the Federal Trade Commission is cracking down on the popular messaging app NGL. Marketplace’s Meghan McCarty Carino is joined by Natasha Mascarenhas, reporter at The Information, for her take on this week’s tech news.

The internet is full of all manner of unsavoriness that is surely corroding our minds and societies. But the kind of rot we’re talking about here is link rot — the disappearance of online content when links turn into “404 Page Not Found.” A recent study from Pew Research suggests almost 40% of all webpages that existed in 2013 are no longer accessible. That includes important government links, citations on Wikipedia and hyperlinks in news articles. Marketplace’s Lily Jamali recently talked about this with Clare Stanton, product and research manager at Harvard Law School’s Library Innovation Lab, who also works on a webpage preservation project, perma.cc.
