If the world hopes to eliminate carbon dioxide emissions by midcentury, nearly half the cuts will have to come from technologies that are only in early stages today. That finding, in a report from the International Energy Agency released Tuesday, points to the need for aggressive investment in research, development, and scale-up of clean energy…

On May 14, China’s space program took a huge leap forward when it landed a rover on Mars for the first time, according to state media. China is now only the second country to land successfully on Mars. The rover, named Zhurong (after the god of fire in ancient Chinese mythology), joins NASA’s Curiosity and…

In 1998 a couple of Stanford graduate students published a paper describing a new kind of search engine: “In this paper, we present Google, a prototype of a large-scale search engine which makes heavy use of the structure present in hypertext. Google is designed to crawl and index the Web efficiently and produce much more…

A man with a brain implant that allows him to control computers via mental signals says he is ready to challenge Elon Musk’s neuroscience company Neuralink in a head-to-head game of Pong—with a monkey. Neuralink is developing advanced wireless brain implants so humans can connect directly to computer networks. In April, researchers working with the…

A year ago, the idea that the covid-19 pandemic could have been caused by a laboratory accident was denounced as a conspiracy theory by the world’s leading journals, scientists, and news organizations. But the origin of the virus that has killed millions remains a mystery, and the chance that it came from a lab has…

Ayanna Howard has always sought to use robots and AI to help people. Over her nearly 30-year career, she has built countless robots: for exploring Mars, for cleaning hazardous waste, and for assisting children with special needs. In the process, she’s developed an impressive array of techniques in robotic manipulation, autonomous navigation, and computer vision.…

The covid-19 pandemic is a catastrophe that could have been averted, say a panel of 13 independent experts tasked with assessing the global response to the crisis. Their report, released May 12 and commissioned by the WHO, lambasts global leaders who failed to heed repeated warnings, wasted time, hoarded information and desperately needed supplies, and…

On May 10, the World Health Organization added a new virus to its list of covid-19 variants of global concern. The variant, B.1.617, is being blamed for the runaway infections in India. It is the fourth addition to a list that also includes variants first identified in the UK, South Africa, and Brazil. “There is some…

Credit scores have been used for decades to assess consumer creditworthiness, but their scope is far greater now that they are powered by algorithms. Not only do they consider vastly more data, in both volume and type, but they increasingly affect whether you can buy a car, rent an apartment, or get a full-time job.…

Emoji are now part of our language. If you’re like most people, you pepper your texts, Instagram posts, and TikTok videos with various little images to augment your words—maybe the syringe with a bit of blood dripping from it when you got your vaccination, the prayer (or high-fiving?) hands as a shortcut to “thank you,”…

Engineers are under unprecedented pressure to build products that are used by thousands, if not millions, of consumers every day. Just ask Bernd Zapf. Head of development, new business, and technologies at Heller Group, a machine tool manufacturer in Germany, Zapf says today’s organizations must increasingly “strike a balance between the design, engineering, manufacturing, operation,…

The Massachusetts Audubon Society has long managed its land in western Massachusetts as crucial wildlife habitat. Nature lovers flock to these forests to enjoy bird-watching and quiet hikes, with the occasional bobcat or moose sighting. But in 2015, the conservation nonprofit presented California’s top climate regulator with a startling scenario: It could heavily log 9,700…

Update 5/9, 12:25 a.m. ET: The US Space Force confirmed the booster landed in the Indian Ocean just north of Maldives late Saturday evening. Last week, China successfully launched Tianhe-1, the first part of its new space station, to be completed before the end of 2022. A week later, the mission is still making huge waves—and…

Several years ago, when Elizabeth Softky first heard of the concept of universal basic income, she had her doubts. She was a public school teacher at the time, and she knew how hard it was to convince people to support even modest financial benefits, like pay raises for her coworkers. “Giving people money? I couldn’t…

The news: A new type of attack could increase the energy consumption of AI systems. In the same way a denial-of-service attack on the internet seeks to clog up a network and make it unusable, the new attack forces a deep neural network to tie up more computational resources than necessary and slow down its…

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.

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,”…

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…
