This spring, while the US government was spinning its wheels on an official covid-19 response, countries around the world were rolling out national contact tracing apps. Beginning with Singapore in mid-March, more than 40 countries have launched digital exposure notification systems, to varying degrees of success. Our Covid Tracing Tracker logs each country’s app and…

Earlier this month a mutated variant of the coronavirus was detected in the UK, setting off alarms across Europe and causing some countries to ban travelers from Britain. But it’s still not clear that the new variant is much more easily transmitted, as some scientists have warned. Moreover, several companies with authorized vaccines or therapeutic…

There are two stories you hear about making a living as an artist in the digital age, and they are diametrically opposed. One comes from Silicon Valley and its boosters in the media. There’s never been a better time to be an artist, it goes. If you’ve got a laptop, you’ve got a recording studio.…

Experts are debating the pros and cons of covid-19 vaccine passports or other types of certification as they attempt to begin reopening public spaces. The idea seems simple on its face: those who can prove they’ve been vaccinated for covid-19 would be able to go places and do things that unvaccinated people would not. There’s…

On November 30, Chinese foreign ministry spokesman Lijian Zhao pinned an image to his Twitter profile. In it, a soldier stands on an Australian flag and grins maniacally as he holds a bloodied knife to a boy’s throat. The boy, whose face is covered by a semi-transparent veil, carries a lamb. Alongside the image, Zhao…

Many companies expected 2020 to be a challenging year. They anticipated technological shifts that would affect their business—like the transition from combustion to electric vehicles for automotive manufacturers—or ongoing instability due to raging trade wars or Brexit. But the impact of the covid pandemic on top of these challenges has, for many companies, been unprecedented.…

In some stores, sophisticated systems are tracking customers in almost every imaginable way, from recognizing their faces to gauging their age, their mood, and virtually gussying them up with makeup. The systems rarely ask for people’s permission, and for the most part they don’t have to. In our season 1 finale, we look at the…

What seemed so impossible at the beginning of the pandemic is now real: vaccines are here, in record time. They bring much-needed hope to a holiday season shadowed by death and fear. While authorities work out details for this mass vaccination campaign, though, the public is still waiting for answers to fundamental questions. Who gets…

When resident physicians at Stanford Medical Center—many of whom work on the front lines of the covid-19 pandemic—found out that only seven out of over 1,300 of them had been prioritized for the first 5,000 doses of the covid vaccine, they were shocked. Then, when they saw who else had made the list, including administrators…

A rising wave of covid-19 cases in the south of England has been blamed on a new variant of the coronavirus. The new version, which appeared by September, is now behind half the cases in the region. Genomic researchers have found that not only does the variant have a lot of mutations, but several of the genetic…

In the early 1970s, Steve Gorad ’63 had a successful career as a clinical psychologist. He was in charge of the alcohol unit at Boston State Hospital and had a private practice, but he was restless. “It wasn’t enough,” he says. “I was a long-haired hippie writing [draft exemption] letters for people who didn’t want…

Looking back to the start of the pandemic, I am struck by our community’s formidable strength. In March 2020, we did not know what it would take to sustain MIT’s great mission through this crisis. Since then, we have found a way together, and we have made it work. That accomplishment belongs to every member…

From the choir rehearsal in Washington to family gatherings in Chicago, numerous covid-19 “superspreading” events have seen one person infect many others. MIT researchers who studied about 60 such events found that they have a much larger impact than expected. “Superspreading events are likely more important than most of us had initially realized,” says senior…

The search for extraterrestrial life has largely focused on Mars, but scientists at MIT, Cardiff University, and elsewhere reported surprising findings in September of what may be signs of life in the clouds of Venus. While Venus is similar to Earth in size, mass, and rocky composition, its surface temperatures reach 900 °F, and its…

How did early humans prepare food before they mastered the use of fire? Research led by Earth, Atmospheric, and Planetary Sciences professor Roger Summons has raised the intriguing possibility that they took advantage of hot springs for boiling. Studying sediments deposited around 1.7 million years ago near Olduvai Gorge in Tanzania, where anthropologists have discovered…

October 12, 2020—Today I ate lunch outside in Cambridge with three of my friends, all fellow Course 16 seniors. I’ve eaten countless lunches with them before: burritos in the Unified lounge, grain bowls at every picnic table in Kendall Square, sushi in the Stud, Chinese food in the lobby of the Koch building. This time…

Each year, the flu vaccine has to be redesigned to account for new mutations. Researchers at MIT and the Ragon Institute of MIT, Mass. General, and Harvard are hoping for a better way. The problem is that while the vaccine prompts production of antibodies against the flu virus, those antibodies tend to target a viral…

When covid-19 hit and the country enacted widespread social distancing measures, the nature of the traditional workplace seemed to change overnight. Technology was already changing the way we work. The office our parents were accustomed to had expanded to employees’ homes, shared conference rooms, and the neighborhood coffee shop. Though remote work was on the…

One cool fall night 10 years ago, Jessica Krieger went for a run to clear her head. Krieger, then an undergraduate in neuroscience, had just watched a documentary that showed the gruesome ways many animals are slaughtered for food. “The animals were terrified, in pain, dying,” she recalls. Krieger was already worried about the meat…

As a machine operator for the robotics startup FarmWise, Diego Alcántar spends each day walking behind a hulking robot that resembles a driverless Zamboni, helping it learn to do the work of a 30-person weeding crew. On a Tuesday morning in September, I met Alcántar in a gigantic cauliflower field in the hills outside Santa…

We won’t easily forget how we worried about food in the first days of the pandemic: empty shelves, scarce products, and widespread hoarding became an alarming reality around the world. While being reassured that the disruptions were “temporary,” Americans also heard troubling news about farmers plowing crops back into their fields, dairy farmers pouring milk…

There’s a long-running column in Cook’s Illustrated called “What is it?” where we track down the origins of kitchen gadgets that our readers find in their attics or on dusty antique-store shelves. A recent favorite: the Acme Rotary Mincer, vintage 1935, a handheld device featuring 10 stainless-steel rotary blades, which promised to mince herbs and…

Lab-grown meat, artificial human breast milk, genetically modified pigs, a cauliflower field farmed by robots—if that’s the kind of science-fiction-y stuff you expect to read about in a special issue on technology and food, you won’t be disappointed.

But a new trend threatens the benefits that cloud computing has unlocked. “Digital sovereignty” describes the many ways governments try to assert more control over the…

Nobel Prizes are rarely awarded without controversy. The prestige usually hatches a viperous nest of critics who deride the credentials of the winner, complain about the unmentioned collaborators who’ll be sidelined by history, or point to the more deserving recipients who’ve been unfairly snubbed. So when the Norwegian committee decided to award the 2020 Nobel…

So what happened? Texas and nine other Republican-led states have filed an antitrust lawsuit against Google, alleging that the company has monopolized digital advertising by means that include anti-competitive agreements with Facebook.
