If you haven’t heard of it before, you’re about to become intimately familiar with the Atlantic Meridional Overturning Circulation. This system of currents—which brings water up the Atlantic from the southern tip of South America, through the tropics, and all the way to the coast of Iceland before looping back down south—plays a key role in keeping our planet’s climate stable. It keeps northern European winters relatively mild, it provides nutrients to ocean life, and it brings much-needed rain to agricultural systems in equatorial zones. Researchers who study the AMOC say this system is showi ..read more

Voice assistants have become a constant presence in our lives. Maybe you talk to Alexa or Gemini or Siri to ask a question or to perform a task. Maybe you have to do a little back and forth with a voice bot whenever you call your pharmacy, or when you book a service appointment at your car dealership. You may even get frustrated and start pleading with the robot on the other end of the line to connect you with a real human. That’s the catch, though: These voice bots are starting to sound a lot more like actual humans, with emotions in their voice, little ticks and giggles in between phrases ..read more

Ozempic has been hailed as a miracle drug. It is the most well known of the GLP-1 medications, a class of drugs that can help regulate appetite, digestion, and blood sugar—and help those suffering from obesity or diabetes lose weight. Naturally, these drugs are very much in demand. But now there is a shortage of Ozempic and other GLP-1s, which has led to a swell of clones that purport to offer the same benefits and the same key ingredient, semaglutide, at lower prices. These clone drugs are easy to procure from telehealth providers, even if a buyer needs to lie about themselves a little bit to ..read more

Back in March, the US Environmental Protection Agency finalized a long in the works rule requiring automakers here to dramatically increase the number of battery-powered vehicles they’re putting on the roads. The government has mandated that by 2032, more than half of new cars sold must be electric. There are some caveats, namely that plug-in hybrid cars will fulfill the federal requirements for what a “battery-powered” vehicle is.  This has led to a flood of hybrid cars hitting the market. This week, we talk about what this means for people who are considering buying a new car now, or in ..read more

Even if you’ve never taken a puff from a vape in your life, you know about Juul. At the company’s peak in 2018, its e-cigarette was one of the most recognizable consumer devices on the planet, and Juul Labs was worth $38 billion. Just a few short years later, after being squeezed by government regulators and prohibition-minded anti-tobacco advocates, Juul’s valuation plummeted and its market share vaporized. The story of Juul—and its thousands of imitators—is outlined in Backfired: The Vaping Wars, a new nine-part podcast from Prologue Projects. The show traces the history of e-cigarettes, nic ..read more

Web crawling—the act of indexing information across the internet—has been around for decades. It has primarily been used by search engines like Google and nonprofits like Internet Archive and Common Crawl to catalog the contents of the open internet and make it searchable. Until recently, the practice of web crawling has rarely been seen as controversial, as websites depended on the process as a way for people to find their content. But now crawling tech has been subsumed by the great AI-ening of everything, and is being used by companies like Google and Perplexity AI to absorb whole articles ..read more

Google has spent the past year lustily rolling out AI features across its platforms. But with each launch, it is becoming more clear that some of these so-called enhancements should have simmered a little longer. The latest update to stoke equal parts excitement and ridicule is AI Overviews, the new auto-generated summary boxes that appear at the top of some Google search results. In theory, AI Overviews are meant to answer questions and neatly summarize key information about people's search queries, offering links to the sources the summaries were pulled from and making search more immediatel ..read more

Domain names have value, even when the websites that were once hosted there are shut down or abandoned. Prospectors will often swoop in and snatch up an unused domain, then erect a new website filled with clickbait articles. If the domain name used to rank highly in search results, the new clickbait articles will also rank highly, guaranteeing the prospector a steady stream of visitors searching the web for common phrases.  These zombie sites are all over the web; you’ve probably landed on them many times yourself. But this shady market is poised to grow exponentially thanks to the prolif ..read more

People everywhere are hot for heat pumps. These electric appliances—which perform the same heating and cooling tasks as traditional HVAC systems, just much more efficiently—have been outselling gas furnaces over the past couple of years. Their proliferation seems to be pointing more towards an energy-conscious electric future in people’s homes. And, four months ago, nine states in the US signed a memorandum of understanding that says that heat pumps should make up at least 65 percent of residential heating, air conditioning, and water-heating shipments by 2030. But, what exactly is a heat pump ..read more

For all the influence Twitter has had on our culture, no community there has made quite as much impact as Black Twitter. The virtual community grew from a loose online hangout to an influential cultural force that directed conversations about race and culture not only on social media, but in our society at large. A new documentary miniseries from Hulu called Black Twitter: A People's History charts that monumental trajectory.   This week on Gadget Lab, we chat about the rise and solidification of Black Twitter with showrunner Joie Jacoby, director and executive producer Prentice Penny, an ..read more
