Since the first ATM was installed in 1967 and New York’s Nasdaq exchange debuted digital trading in 1971, the financial services industry has been a frontrunner in technological innovation. But for decades, technology remained a back-office affair, servicing traders and executives who called the shots. Today, however, technology has been propelled to the top of…

The US is launching a trial for blood tests that promise to catch cancers earlier The news: The US is launching a national trial to assess how effective tests designed to spot signs…

Most cancers can’t be reliably screened for before symptoms begin—tools like mammograms and pap smears are exceptions, not the rule. To improve detection, dozens of companies have designed single tests to spot signs of multiple kinds of cancer in blood drawn from a patient’s arm. Now, a national trial is preparing to launch in the…

It’s no secret that digital predators are lurking online in record numbers, exposing others to harmful language, images, videos, and activities. With 300 hours of user-generated content uploaded to the internet every minute, protecting unsuspecting users has become a mammoth task. According to Variety, user-generated content represents 39% of all time spent with media. So,…

If today’s metaverse were a shopping mall, you could visit any number of department stores, each with its own rich selection of products and experiences. You could pop into virtual platforms like Roblox to buy a new outfit for your avatar or stop by Decentraland to gauge the latest valuation of digital real estate. You…

Here’s a thought experiment: It’s just a few years from now, and you’re shopping for new sneakers. You get a mobile notification from your favorite retailer—a pair you’ve been eyeing is on sale. You promptly grab your VR glasses and step into a digital representation of the store, where you design your fully personalized shoes,…

I took an international trip with my frozen eggs to learn about the fertility industry Like me, my eggs were flying economy class, writes Anna Louie Sussman. My dog Stewie and I were…

Like me, my eggs were flying economy class. We—my dog Stewie and I—were in seat 8D, while 12 of my cryopreserved oocytes, four straws of three eggs each, had a window seat further back. They were ensconced in a cryogenic storage flask, known as a dewar, which was packed into a rolling metal suitcase the…

Roblox users will soon be able to give their avatars facial expressions that mimic the player’s own, the platform announced today.

How conservative Facebook groups are changing what books children read in school Conservative Facebook groups that rate and review children’s books are being used as a way to campaign for restricting certain books…

A new x-ray technique that works alongside a deep-learning algorithm to detect explosives in luggage could eventually catch potentially deadly tumors in humans. Concealing explosives inside electronics and other objects can make it difficult to detect them using conventional x-ray techniques. But the new method was able to detect explosives with 100% accuracy under test…

Conservative Facebook groups that rate and review children’s books are being used as a way to campaign for restricting certain books in school libraries or removing them altogether. It’s the latest development in a debate tearing up the US in recent weeks as schools open for the new year. In October 2021, Matt Krause, a…

The covid-19 pandemic is still not over. And while injected vaccines provide good protection from severe disease, they don’t stop us from catching the virus or spreading it to others. Vaccines that you inhale through the nose or mouth, on the other hand, potentially could. In the last week, regulatory bodies in both India and…

As more business, shopping, and banking is done online and from, well, anywhere, customers increasingly expect high-quality digital-first services that remove the need to go into a physical store or bank. “People were working from home, shopping from home, banking from home, and are more tech and digital savvy than ever,” says Mike Dargan, group…

If you were just looking at his LinkedIn page, you’d certainly think Mai Linzheng was a top-notch engineer. With a bachelor’s degree from Tsinghua, China’s top university, and a master’s degree in semiconductor manufacturing from UCLA, Mai began his career at Intel and KBR, a space tech company, before ending up at SpaceX in 2013.…

In today’s digital economy, people buy things differently. Customers expect interactions with companies to be thoughtful, customized, curated, and most importantly, quick. These experiences drive—and are driven by— technology’s constant progress. However, the advance of technology can cause headaches for the businesses delivering these interactions, even with the most talented product and delivery teams. Customization…

A unique form of brain stimulation appears to boost people’s ability to remember new information—by mimicking the way our brains create memories. The “memory prosthesis,” which involves inserting an electrode deep into the brain, also seems to work in people with memory disorders—and is even more effective in people who had poor memory to begin…

Long before Alexander Cohen—or anyone else—had heard of the alpha, delta, or omicron variants of covid-19, he and his graduate school advisor Pamela Bjorkman were doing the research that might soon make it possible for a single vaccine to defeat the rapidly evolving virus—along with any other covid-19 variant that might arise in the future. …

It’s a Thursday afternoon, and I should be at work. Instead, I’m chasing my toddler around the small, disheveled garden behind my doctor’s office, along with around 15 other parents. We’re all here for the same reason—to get our young children vaccinated against polio. “We’re doing about 200 children today,” the nurse tells me. My…

In his first month in office, US President Joe Biden signed an executive order calling for the nation to eliminate carbon pollution from the electricity sector by 2035 and achieve net-zero emissions across the economy by 2050. That move redefined the mandate of the US Department of Energy’s Office of Fossil Energy, the research agency…

After years of requests, Twitter is finally introducing an edit button, giving its users the ability to change their tweets up to 30 minutes after they’ve been sent. But the feature is unlikely to solve any of the biggest problems facing the company—and in some cases, it could worsen them. The feature will initially be…

During the covid-19 pandemic, antibodies played a front-and-center role. We used home tests to look for them, and we took vaccines so our bodies would make more. Less attention was paid to B cells, the immune-system cells that actually make antibodies, churning out as many as 10,000 a second—and which, after an infection, can persist…

For a reporter who covers AI, one of the biggest stories this year has been the rise of large language models. These are AI models that produce text a human might have written—sometimes so convincingly they have tricked people into thinking they are sentient. These models’ power comes from troves of publicly available human-created text…

Ammonia might seem like an unlikely fuel to help cut greenhouse-gas emissions. Best known for its odor, the gas can be dangerous and toxic. But it could also play a key role in decarbonizing global shipping, providing an efficient way to store the energy needed to power large ships on long journeys. The American Bureau…

Roger Nichols remembers sending his first e-mail using wireless networks in the early 1990s, from the back of a bus during his daily commute. That was 30 years ago, on a 1G network—at a data rate about fifteen thousand times slower than today. Now the 6G program manager at Keysight Technologies, Nichols sees the rapid…

As the covid pandemic raged in late 2020, all eyes turned briefly from our troubled planet to our planetary neighbor Venus. Astronomers had made a startling detection in its cloud tops: a gas called phosphine that on Earth is created through biological processes. Speculation ran wild as scientists struggled to understand what they were seeing. …

I Was There When is an oral history project that’s part of the In Machines We Trust podcast.

As a globally unprecedented 70-day heat wave continues to hold its grip on southern China, with the highest temperature as much as 113°F (45°C), severe droughts and shortages in the hydropower supply are wreaking havoc on the lives of residents. Electric vehicle owners are one group particularly feeling the heat. Since public charging posts are temporarily closed…

The most viewed post on Facebook last quarter was a 69 joke, featuring reposted footage from an episode of the TV show Family Feud. The post, originally an Instagram Reel, had more than 52 million views on Facebook, according to Meta’s quarterly report on the most widely viewed content on the platform in the US.…

In the coming weeks, a volunteer in Boston, Massachusetts, will be the first to trial a new treatment that could end up creating a second liver in their body. And that’s just the start—in the months that follow, other volunteers will test doses that could leave them with up to six livers in their bodies.…

Mouse embryos recently generated from stem cells in a lab show more brain development than any synthetic mouse embryos created previously. While other researchers had created mouse embryos from stem cells, none had reached the point where the entire brain, including the anterior portion at the front, began to develop, according to the researchers from…

The Inflation Reduction Act, which US President Joe Biden signed into law last week, will steer tens of billions of dollars into projects designed to capture carbon dioxide that would otherwise be released from power plants and industrial facilities. That provision is proving to be one of the more controversial climate items in the sweeping…

In 2019, Amazon committed to achieving “net-zero carbon” across its businesses by 2040. The online retail behemoth’s company-wide emissions have soared by 40% since then, topping 70 million metric tons of carbon dioxide last year. It’s a glaring example of the gulf between corporate pledges and climate progress, but far from the only one. Numerous…

Doctors can’t tell a person’s race from medical images such as x-rays and CT scans. But a team including MIT researchers was able to train a deep-learning model to identify patients as white, Black, or Asian (according to their own description) just by analyzing such images—and they still can’t figure out how the computer does…

The MIT inventors of tiny artificial muscles that flap the wings of robotic insects have now added electroluminescent particles that enable them to emit colored light during flight, similar to fireflies. The artificial muscles, called actuators, are made by alternating ultrathin layers of elastomer and carbon nanotube electrode material and then rolling the stack of…

In April, design major Karyn Nakamura ’23 transformed Simmons Hall into an interactive art project. Her piece, titled “116 x 31” after the number of squares in Simmons’s façade, converted audio into dynamically projected color patterns evocative of vintage video games.
