The explosive successes of AI in the last decade or so are typically chalked up to lots of data and lots of computing power. But benchmarks also play a crucial role in driving progress—tests that researchers can pit their AI against to see how advanced it is. For example, ImageNet, a public data set of…

Researchers have spent years trying to crack the mystery of how we express our feelings. Pioneers in the field of emotion detection will tell you the problem is far from solved. But that hasn’t stopped a growing number of companies from claiming their algorithms have cracked the puzzle. In part one of a two-part series…

Automated driving is advancing all the time, but there’s still a critical missing ingredient: trust. Host Jennifer Strong meets engineers building a new language of communication between automated vehicles and their human occupants, a crucial missing piece in the push toward a driverless future. We meet: Dr. Richard Corey and Dr. Nicholas Giudice, founders of…

China’s president, Xi Jinping, has announced plans for the nation to become carbon neutral by 2060, setting a bold goal for the world’s biggest climate polluter. But it’s hard to reconcile Xi’s pledge, made before the UN General Assembly on Tuesday, with the nation’s recent actions. Most notably, China is in the midst of a…

“If God wanted man to become a spacefaring species, He would have given man a moon.” The famed rocket scientist Krafft Ehricke uttered those words in 1984. He wanted to highlight how we could use the moon as a springboard to expand human civilization into the rest of the solar system. This was more than…

In March, Adobe’s leadership team decided—for the sake of employee well-being—to institute worldwide work-from-home policies to protect against the spread of covid-19. And it was a large undertaking. This content was produced by Adobe. It was not written by MIT Technology Review’s editorial staff. Anil Chakravarthy is Executive Vice President and General Manager of Adobe’s…

Over a year ago, scientists unleashed something incredible on the world: the first photo of a black hole ever taken. By putting together radio astronomy observations made with dishes across four continents, the collaboration known as the Event Horizon Telescope managed to peer 53 million light-years away and look at a supermassive black hole, which…

The news: On September 22, Microsoft announced that it would begin exclusively licensing GPT-3, the world’s largest language model, built by San Francisco–based OpenAI. The model acts like a powerful autocomplete: it can generate essays given the starting sentence, songs given a musical intro, or even web page layouts given a few lines of HTML…

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,…

America’s most famous spy agency has a major competitor it can’t quite seem to beat: Silicon Valley. The CIA has long been a place cutting-edge technology is researched, developed, and realized—and it wants to lead in fields like artificial intelligence and biotechnology. However, recruiting and retaining the talent capable of building these tools is a…

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…

The news: An international consortium of medical experts has introduced the first official standards for clinical trials that involve artificial intelligence.

Facebook unveiled a new product today called Facebook Campus: “a college-only space designed to help students connect with fellow classmates over shared interests.” Sound familiar? Campus appears to be a throwback to the first days of Facebook, when a person had to have a college email address and attend a select group of universities to…

Russian military hackers responsible for cyberattacks against Democratic targets during the 2016 American election are now targeting over 200 organizations in the United States (including political parties, think tanks, and consultants serving both Democrats and Republicans), according to Microsoft, which is increasingly calling out Russian cyber espionage. In the final weeks before the November 3…

Brazil is grappling with a crisis of misinformation. To solve it, the country should be investing in education and holding the financiers of fake-news networks accountable. Instead, Brazil’s National Congress is considering legislation that would violate the privacy and freedom of expression of the country’s 137 million internet users. Several members and supporters of President…

Earlier this year, before the pandemic and lockdowns, audio engineer Stéphane Pigeon received an unusual request: would he consider making sounds that replicated the office? “I said, ‘No, no, no, I will not do it!’” says Pigeon, the creator of myNoise.net, which has become a cult resource among people looking for background noise to help…

Every week, the readers of our space newsletter, The Airlock, send in their questions for space reporter Neel V. Patel to answer. This week: How the average person can go to space.

US president Donald Trump and his Democratic opponent, Joe Biden, agree on at least one issue: the arcane federal law known as Section 230 of the Communications Decency Act. On September 8, Trump tweeted that Republican lawmakers should “repeal Section 230, immediately.” With similar urgency, Biden had told the New York Times last December that…

The news: AstraZeneca has paused its global phase 3 covid-19 vaccine trial after a UK participant fell seriously ill. It’s unclear if the suspected “serious adverse reaction” was a result of receiving the vaccine or coincidental, but the person affected is expected to recover, according to STAT. We also don’t know how long the trial…

Over the past six months, central banks and governments have unlocked financial floodgates to deal with the economic fallout of covid-19. As early as April, 106 countries had introduced or adapted social protection programs, mostly cash transfers, to help those affected by the pandemic. A McKinsey analysis of 54 countries estimates that governments had committed $10 trillion by June,…

On September 6, China successfully landed a reusable spacecraft the country had launched into orbit just two days before, according to the state-run Xinhua News Agency. “The successful flight marked the country’s important breakthrough in reusable spacecraft research and is expected to offer convenient and low-cost round trip transport for the peaceful use of the…

A large geometric concrete structure sits on the busy corner of Canal and West Streets in Lower Manhattan. Passersby wondering at its function may guess it’s a museum, or an art gallery. Few are likely to hit on the reality: a salt shed. And that was exactly the intent, says Richard Dattner ’60, lead designer…

Many years after meeting in a freshman fencing class, Tom and Betsy (Beliveau) Davis were reacquainted and eventually married. Their shared undergraduate experience led them to establish the Tom and Betsy Davis Scholarship Fund, which has helped two students attend MIT. A bequest plan—developed with the MIT Office of Gift Planning—ensures that the fund will…

When Mark Zuckerberg announced that Facebook would stop accepting political advertising in the week before the US presidential election, he was responding to widespread fear that social media has outsize power to change the balance of an election. Political campaigns have long believed that direct voter contact and personalized messaging are effective tools to convince people to vote for a particular candidate. But in 2016, it seemed that social media was amplifying…

On August 31, Airbnb launched Project Lighthouse, an initiative meant to “uncover, measure, and overcome discrimination” on the home-sharing platform. According to the company, Project Lighthouse will identify discrimination by measuring whether a renter’s perceived race correlates with differences in the rate or quality of that person’s bookings, cancellations, or reviews. This project comes amid…

About a year after graduating from college, I packed my possessions into a rental van I’d split with a near stranger and departed my home state of Ohio. We steered onto I-70 West, bound for San Francisco. At the time, I was less drawn to California in any specific way than determined to escape a…

Amba Kak was in law school in India when the country rolled out the Aadhaar project in 2009. The national biometric ID system, conceived as a comprehensive identity program, sought to collect the fingerprints, iris scans, and photographs of all residents. It wasn’t long, Kak remembers, before stories about its devastating consequences began to spread.…

Back in July, OpenAI’s latest language model, GPT-3, dazzled with its ability to churn out paragraphs that look as if they could have been written by a human. People started showing off how GPT-3 could also autocomplete code or fill in blanks in spreadsheets. In one example, Twitter employee Paul Katsen tweeted “the spreadsheet function…

The Google Magenta team, which makes machine-learning tools for the creative process, has made models that help you compose melodies, and tools that help you sketch cats. Mostly because it’s fun, but also to explore how AI can make creation more accessible. Its latest project now gives anyone a chance to make quarantine tunes to…

Long before the world had ever heard of covid-19, Kay Tye set out to answer a question that has taken on new resonance in the age of social distancing: When people feel lonely, do they crave social interactions in the same way a hungry person craves food? And could she and her colleagues detect and…

In a high-level report precipitated by the birth of CRISPR babies in China in 2018, scientists say the technology’s next medical use should be narrowly restricted to prospective parents who can’t otherwise have a healthy child, such as Black couples who both have sickle-cell disease. The 200-plus-page report, from the US National Academies and the…

The news: Since April, the Delphi research group at Carnegie Mellon University has been compiling one of the world’s largest databases for covid-19 symptom tracking. Now it’s launching a new challenge with Facebook and other partners to crowdsource data projects for improving the nation’s pandemic response. The data: The Delphi group, one of the best…

When Kyle Rittenhouse shot and murdered protesters in Kenosha, Wisconsin, it wasn’t just the act of a lone vigilante; it was a direct consequence of white militia groups’ organizing on social media. Since June, right-wing media makers have recorded and circulated videos of violent altercations at protests in cities including New York, Boston, Philadelphia, Los…
