A dozen covid-19 vaccines are now being used around the world. Most require two doses, and health officials have warned against mixing and matching: the vaccines, they argue, should be administered the way they were tested in trials. But after emerging concerns about the very rare risk of blood clots linked to the Oxford-AstraZeneca vaccine,…

In March 2017, a group of hackers from China arrived in Vancouver with one goal: Find hidden weak spots inside the world’s most popular technologies. Google’s Chrome browser, Microsoft’s Windows operating system, and Apple’s iPhones were all in the crosshairs. But no one was breaking the law. These were just some of the people taking…

Uploading personal photos to the internet can feel like letting go. Who else will have access to them, what will they do with them—and which machine-learning algorithms will they help train? The company Clearview has already supplied US law enforcement agencies with a facial recognition tool trained on photos of millions of people scraped from…

The night before the Facebook Oversight Board decided to stand by the company’s decision to ban him from its platforms, former president Donald Trump announced—via an exclusive on Fox News—that he’d created a website. Called From the Desk of Donald Trump, it looked like a social media site but was really just a feed of…

Over-the-counter home tests for covid-19 are finally here. MIT Technology Review obtained kits sold by three companies and tried them out. After buying tests from CVS and online, I tested myself several times and ended up learning an important lesson: while some people worry that home tests could miss covid cases, the bigger problem may…

Jennifer Xiong spent her summer helping Hmong people in California register to vote in the US presidential election. The Hmong are an ethnic group that come from the mountains of China, Vietnam, Laos, and Thailand but don’t have a country of their own, and Xiong was a volunteer organizer at Hmong Innovating Politics, or HIP,…

There’s nothing new about conspiracy theories, disinformation, and untruths in politics. What is new is how quickly malicious actors can spread disinformation when the world is tightly connected across social networks and internet news sites. We can give up on the problem and rely on the platforms themselves to fact-check stories or posts and screen…

In a cruel irony, India, the world’s vaccine manufacturing powerhouse, is now crippled by a virus for which multiple safe and effective vaccines have been developed in record time. Official reports of more than 380,000 new cases and 3,400 deaths daily, while staggering, likely underestimate the actual toll. As health systems across India buckle under…

At 11:23 a.m. local time Thursday at Wenchang, Hainan Island, China launched Tianhe-1, the first module of a new orbital space station. It’s scheduled to be operational by the end of 2022. The launch, which went flawlessly, sets China up for a very busy next two years as it seeks to build upon the decade’s…

Kian Kelley-Chung was wearing a black T-shirt with the logo of his documentary and art collective on the day last summer when he found himself filming the Washington, DC, police during a protest. It was August 13, 2020, and Kelley-Chung had been recording Black Lives Matter demonstrations in the city for a couple of months.…

Developing the capacity to annotate massive volumes of data while maintaining quality is a function of the model development lifecycle that enterprises often underestimate. It’s resource intensive and requires specialized expertise. At the heart of any successful machine learning/artificial intelligence (ML/AI) initiative is a commitment to high-quality training data and a pathway to quality data…

By any measure, 2021 corporate planning isn’t business as usual. As the coronavirus pandemic grinds on, financial services institutions are coming out of crisis mode— addressing immediate cash management and operational challenges—with a renewed readiness for business growth. Fortunately, most businesses across industries are doing a good job of navigating the pandemic and its economic…

Tens of millions of people in the United States have now been fully vaccinated against covid-19. These people are seeing friends, eating out, and—in rare cases—getting infected. But we shouldn’t panic: these kinds of “breakthrough infections” are entirely expected with any mass vaccine rollout. According to new figures released by the Centers for Disease Control and Prevention, more…

Last week US regulators recommended resuming use of the Johnson & Johnson vaccine, after deciding that a side effect involving blood clots was too rare to justify continuing the brief suspension they had imposed: there were just 15 reported instances out of 8 million doses. But even though the pause lasted just 11 days, it…

Along the coast of Northern California near the Oregon border, the cool, moist air off the Pacific sustains a strip of temperate rainforests. Soaring redwoods and Douglas firs dominate these thick, wet woodlands, creating a canopy hundreds of feet high. But if you travel inland the mix of trees gradually shifts. Beyond the crest of…

Today’s voice assistants are still a far cry from the hyper-intelligent thinking machines we’ve been musing about for decades. And it’s because that technology is actually the combination of three different skills: speech recognition, natural language processing and voice generation. Each of these skills already presents huge challenges. In order to master just the natural…

They drilled a hole in my skull on the 43rd floor of an empty skyscraper in Lower Manhattan. One of those towers where they told people to go and work from home and they never came back. Floor-to-ceiling windows, beige and white walls, spaces that felt impossibly big now that the cubicle dividers have vanished.…

Science fiction is full of cities imagined from the ground up, but an author who writes about a real place has to engage with real cultures and real histories. It takes a special kind of world-building skill to develop a city when its origins are already known. The Membranes, a fascinating new book out in…

Construction workers in New York’s Lower Manhattan neighborhood were breaking ground for a new federal building back in 1991 when they unearthed hundreds of coffins. The more they dug, the more they found—eventually uncovering nearly 500 individuals, many buried with personal items such as buttons, shells, and jewelry. Further investigation revealed that the remains were…

Fourteen-year-old Neha Dashrath was ecstatic when the pizza arrived. It was the first time she’d ever ordered from a food delivery app. “I always felt shy when my friends talked about ordering food from apps,” she says. “Now I, too, can show off.” Dashrath lives in Laxmi Nagar, a slum in Pune, Maharashtra, alongside some…

Power outages are a way of life in Africa’s most industrialized country. Over the last decade, South Africa’s electricity grid has come apart at the seams and failed to deliver dependable power. As renewable energy gets cheaper, South African cities such as Cape Town have demanded the right to find their own sources. The primary…

Teresa Mosqueda used to spend her days asking people to run for office. A union leader and third-generation Mexican-American from Seattle, she figured the most effective way to address working families’ issues was to encourage people who had once experienced them to enter politics. But when people would ask her to run, Mosqueda would decline,…

Finding your way through Rocinha in Rio de Janeiro is not easy. The buildings are densely and turbulently arranged in a manner that defies traditional identification systems like street names and numbers. Rocinha is a favela, one of the largest among hundreds of unplanned settlements that have sprung up on the outskirts of Brazilian cities…

The coronavirus pandemic presents a cruel irony for urban dwellers. What good are cities if the very quality that makes them so dynamic—the ease of connecting with people and gathering in large groups for everything from a baseball game to an opera—now renders them more dangerous than before? That question lies at the heart of…

Sohini Chattopadhyay had almost given up her medical quest before deciding to try one last bizarre idea. Chattopadhyay, 30, and her friends were looking for a plasma donor for a childhood pal who was battling covid-19 in the eastern Indian city of Kolkata. The woman’s oxygen levels were plummeting, and doctors said that “convalescent plasma,”…

Emerson Yearwood, who has spent most of his career as an attorney in the communications sector, is dedicated to supporting students of color at MIT through his giving and volunteerism. His current focus is the Black Alumni of MIT Community Advancement Program and Fund (BCAP), which supports student proposals for public service projects that address…

Most amputations sever the muscle pairs that control joints such as the elbow or ankle, disrupting the sensory feedback about the limb’s position in space that would help patients control a prosthesis. But a surgical technique developed by MIT researchers appears to leave amputees with both greater control and less pain than people who have…

New Vassar, MIT’s new undergrad dorm, opened in January across the street from the Henry Steinbrenner Stadium and Track with the goal of promoting a healthy, well-balanced lifestyle. The 450-bed residence emphasizes four core values chosen by its founders’ group: well-being, inclusiveness, adventure, and kindness. Dining options will eventually include a cooking pod program that…

One morning at the start of the spring semester, I was surprised by a most welcome sound outside: the voices of students! I could not resist going to the window. Even bundled up against the cold, the students were obviously excited to be back on campus—or in the case of first-years, to be on campus…

Like meat production, logging and agriculture can exact a heavy environmental toll. Now an MIT team has proposed a way to circumvent that by growing certain plant tissues in the lab—an idea somewhat akin to cultured meat. The researchers, in Luis Fernando Velásquez-García’s group at the Micro­systems Technology Laboratories, grew wood-like plant tissue indoors, without…

Christopher Rose ’79, SM ’81, PhD ’85, earned three MIT degrees in electrical engineering but has always been drawn to many disciplines.

Third-party cookies are like Cretaceous dinosaurs. They’re munching away on consumers’ data while asteroids lobbed by Google, Mozilla, Apple, and others are on the brink of obliterating the current marketing ecosystem. Google is planning to phase out these online tracking tools by 2022. For its part, Apple plans to make its mobile device ID—known as…

The news: Oxygen and other vital medical supplies have started arriving in India as it battles one of the most acute covid-19 crises any country has experienced yet. The country set a global record for new cases for the fifth day in a row yesterday, reporting 352,991 and 2,812 deaths. The true figure is almost…

The data scientist Youyang Gu thinks of himself as a realist—he declares it in his Twitter profile: “Presenter of unbiased takes. Realist.” When he noticed the scattershot covid-19 projections last spring—one model projected 2 million US deaths by the summer, another predicted 60,000—Gu questioned whether that was as good as the modeling could be. He…

Bill Gates made headlines earlier this year for saying that “all rich countries should move to 100% synthetic beef” in an interview with MIT Technology Review about the release of his new book, How to Avoid a Climate Disaster. Although he recognized the political difficulty of telling Americans they can’t eat any more red meat,…

These days we are all striving for connections. In families, between generations, in neighborhoods, and even among co-workers. We rely on it for learning, for trading, for economic growth, for innovation and for global change. Audrey Choi is the Chief Sustainability Officer and Chief Marketing Officer at Morgan Stanley. If we didn’t know it before,…

On paper, the task was gargantuan. To slow the rapid spread of the coronavirus, the New York City subway would start closing every night for the first time in 115 years. That meant the Metropolitan Transportation Authority (MTA), its overseer, had to create a massive bus network to mirror 665 miles of track. That’s roughly…

When Aaron Ring began testing blood samples collected from covid-19 patients who had come through Yale–New Haven Hospital last March and April, he expected to see a type of immune protein known as an autoantibody in at least some of them. These are antibodies that have gone rogue and started attacking the body’s own tissue;…

At the turn of the 20th century, a German horse took Europe by storm. Clever Hans, as he was known, could seemingly perform all sorts of tricks previously limited to humans. He could add and subtract numbers, tell time and read a calendar, even spell out words and sentences—all by stamping out the answer with…

NASA’s Perseverance rover has successfully generated breathable oxygen on Mars. The demonstration, carried out by the rover’s MOXIE instrument on April 20, could lay the groundwork for helping future astronauts establish a sustainable colony on the planet. What’s MOXIE and how does it work? Short for Mars Oxygen In-Situ Resource Utilization Experiment, it’s a toaster-size…

The news: The US will pledge at a summit of 40 global leaders today to halve its carbon emissions from 2005 levels by 2030. This far exceeds an Obama-era pledge in 2014 to get emissions 26-28% below 2005 levels by 2025. The hope is that the commitment will help encourage India, China, and other major…

One February afternoon, a 50-year-old Asian woman was waiting in line at a bakery in Queens, New York, when a man threw a box of spoons at her and then shoved her so violently she required 10 stitches in her head. In a surveillance video, a crowd watches as the man attacks the woman, doing…

A new startup called Orchid is offering the chance for couples planning a pregnancy to learn their odds of passing on risks for common conditions like Alzheimer’s, heart disease, type 1 and 2 diabetes, schizophrenia, and certain cancers to their future child. Existing pre-conception tests, which are widely available, can tell parents whether their children…

It’s a bumper week for government pushback on the misuse of artificial intelligence. Today the EU released its long-awaited set of AI regulations, an early draft of which leaked last week. The regulations are wide ranging, with restrictions on mass surveillance and the use of AI to manipulate people. But a statement of intent from…

More than 132 million people in the US have received at least one dose of a covid-19 vaccine, and as of this week, all Americans over 16 are eligible. But while the US has vaccinated more people than any other country in the world, vulnerable people are still falling through the cracks. Those most affected…

The news: NASA has flown an aircraft on another planet for the first time. On Monday, April 19, Ingenuity, a 1.8-kilogram drone helicopter, took off from the surface of Mars, flew up about three meters, then swiveled and hovered for 40 seconds. The historic moment was livestreamed on YouTube, and Ingenuity captured the photo above…

At a conference in New Orleans in 2007, Jon Greiner, then the chief of police in Ogden, Utah, heard a presentation by the New York City Police Department about a sophisticated new data hub called a “real time crime center.” Reams of information rendered in red and green splotches, dotted lines, and tiny yellow icons…
