The square-faced, three-legged alien shoves and jostles to get at the enormous plant taking over its tiny planet. But each bite just makes the forbidden fruit grow bigger. Suddenly the plant’s weight flips the whole sphere upside down and all the little creatures drop into space. Quick! Reach in and catch one! Agence, a short…

The evidence that the coronavirus spreads through the air has been mounting for months. However, the official guidance from the World Health Organization and Centers for Disease Control is still that droplets are the main route of transmission. In fact, the CDC changed its website last month to acknowledge airborne transmission as a route for…

Elections are a technology. I don’t mean just that they rely on technology, although cybersecurity, voter data, misinformation, and online advertising are all central to how today’s elections are fought. I mean elections are themselves are a technology—an essential mechanism in the running of a healthy society. Elections enable power to alternate between different factions…

Russia’s biggest technology company enjoys a level of dominance that is unparalleled by any one of its Western counterparts. Think Google mixed with equal parts Amazon, Spotify and Uber and you’re getting close to the sprawling empire that is Yandex—a single, mega-corporation with its hands in everything from search to ecommerce to driverless cars. But…

When the 2020 coronavirus pandemic forced workers across the United States to stop congregating in offices and work from home, Siemens USA was prepared to protect its newly remote workforce and identify and repel potential data breaches.

What happens when a major city allows the coronavirus to rage unchecked? If the Brazilian city of Manaus is any answer, it means about two-thirds of the population could get infected and one person in 500 could die before the epidemic winds down. During May, as the virus spread rapidly in Manaus, the equatorial capital…

A dozen or so steep-roofed buildings cling to the edges of an open-pit mine. High above them, on top of an enormous rock arch, sits an inaccessible house. Elsewhere, a railway on stilts circles a group of multicolored tower blocks. Ornate pagodas decorate a large paved plaza. And a lone windmill turns on an island,…

Corporations have never been able to cleanly separate their activities from geopolitics. Now, technology firms are finding it increasingly difficult to work across the US-China divide. Try as they might to cross-pollinate through research and investments, the climate between China and the United States continues to deteriorate into political one-upmanship, leaving users to pay the…

Will the US government ban TikTok and WeChat, or won’t it—and why? With the Trump administration issuing vaguely phrased executive orders and policies about the apps, even as legal challenges against potential bans move through the courts and the president gives his “blessing” to a deal to keep TikTok in US app stores, it’s hard…

What’s going on? The US Commerce Department issued an order banning Americans from downloading Chinese-owned apps TikTok and WeChat at the end of last week. A lot has changed since then. First, TikTok: Back in August, President Donald Trump said TikTok had to either be bought by a US entity by September 15 or face…

What’s happening? The US Commerce Department has issued an order banning Americans from downloading Chinese-owned apps TikTok and WeChat; it’s due to come into effect on Sunday, September 20. Existing users in the US will still be able to use the apps, but they won’t receive updates or patches from Sunday onwards, and the apps…

For the first time ever, a patient’s death has been linked directly to a cyberattack. Police have launched a “negligent homicide” investigation after ransomware disrupted emergency care at Düsseldorf University Hospital in Germany. The victim: Prosecutors in Cologne say a female patient from Düsseldorf was scheduled to undergo critical care at the hospital when the…

For the past couple of years, Courtney Cochran hosted a Nashville-based meetup group called the Snail Mail Social Club. Before the pandemic, it involved people gathering, pen and paper in hand, to write letters together. “It was a fun social endeavor,” Cochran says. “You got some face-to-face connecting time with people.” When the coronavirus made…

When it comes to imagining the future, customer service often gets painted in a dystopian light. Take the 2002 sci-fi film Minority Report. Tom Cruise’s John Anderton walks into the Gap, an identity recognition system scans him, and a hologram asks about a recent purchase. There’s something unsettling in this vignette—an unsolicited non-human seems to…

Algorithms can change the course of children’s lives. Kids are interacting with Alexas that can record their voice data and influence their speech and social development. They’re binging videos on TikTok and YouTube pushed to them by recommendation systems that end up shaping their worldviews. Algorithms are also increasingly used to determine what their education…

US President Donald Trump has successfully moved the nation backwards on climate change, even as the world grapples with increasingly devastating fires, heat waves and droughts. His rollbacks of major environmental policies, should they survive legal challenges and subsequent administrations, could pump the equivalent of 1.8 billion additional metric tons of carbon dioxide into the…

Five of California’s 10 largest fires in modern history are all burning at once. Together, this year’s wildfires have already destroyed 4,200 buildings, forced hundreds of thousands of people to flee their homes, and scorched more than 3.2 million acres across the state. That’s larger than Yellowstone and Yosemite National Parks combined, and nearly half…

Leading discussions about the global rules to regulate digital privacy and surveillance is a somewhat unusual role for a developing country to play. But Brazil had been doing just that for over a decade. Edward Snowden’s bombshell in 2014 detailing the US National Security Agency’s digital surveillance activities changed all that. It included revelations that the…

Venus has long played second fiddle to its redder, smaller, and more distant sibling. Given how inhospitable we’ve learned Venus to be, we’ve spent the majority of the last century pinning some of our biggest hopes of finding signs of extraterrestrial life on Mars. That all changed this week. On Monday it was announced that a…

In the 1950s, Albert Sabin was searching for an improved polio vaccine. To that end, his lab infected the brains of mice, chimpanzees, and monkeys with the virus that causes the disease. They wanted to see if the pathogen would change and if weakened forms might arise. They eventually isolated versions of the polio virus…

America has successfully launched national innovation missions time and again. These missions have delivered life-saving drugs, sparked the computer and internet revolutions, and put humans on the moon. Most recently, the US government has poured billions of dollars into a national innovation campaign to help pharmaceutical companies develop vaccines and therapeutics for covid-19. Yet the…

If you ever found yourself on Venus, you’d be destroyed in moments. The pressure at the surface is thought to be up to 100 times greater than what is found on Earth, temperatures are around 464 °C, and the air is more than 96% carbon dioxide. And yet, life on Venus suddenly isn’t the most…
