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...

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 lo...

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 ne...

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...

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-cigarett...

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 whol...

This week, Apple executives used the keynote address of the company’s annual developers conference to debut all of the artificial intelligence capabilities that are coming to iPhones, iPads, and Macs. The team showed off how generative tools will help users write emails, clean up iPhone photos, illustrate presentations, and make custom emoji characters. 

Adding AI to everything is par for the course in 2024, as all of the big tech companies have been loading up their software with similar generative features. But Apple is late to this particular party. The company has been perceived as being “behind” in gene...

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 immediately useful...

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 tha...

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? How does it work...
