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…

This story is one of a series about how hidden innovations produce the foods we eat at the prices we pay. It has been edited for length and clarity. As told to Krithika Varagur. We get our beans from the Ivory Coast, Cameroon, Ecuador, the Dominican Republic, Peru, Colombia, and right here in Mexico. Since…

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. (And if you like actual science fiction, take a look at this short story by Anjali Sachdeva.) …

Blockchain Chicken Farm, a new book from Oakland-based writer, designer, and scholar Xiaowei Wang, explores technology in rural China and the surprising ripple effects of the country’s food supply chain on people all around the world. The book connects, for example, an AI-driven pig-farming operation in Guangdong to Silicon Valley surveillance culture, while avoiding the…

The National Agricultural Statistics Service is used to set nationwide estimates of agricultural commodities. We have 12 regions across the country,…

When he was growing up, Venkatesh Mannar and his siblings treated the family saltworks as their playground: they would slide down mountains of salt drying in the sun the way other children might sled down snow-covered hillsides. The salt operation, in the southern Indian port city of Thoothukudi, had been founded by his grandfather’s grandfather.…

Forty attorneys general representing both Republican- and Democratic-led states and territories have filed a new antitrust lawsuit against Google claiming that the company has “virtually untrammeled power over internet search traffic” as a result of its “overwhelming and durable monopoly in general internet searches.” The move comes one day after another complaint filed by Texas…

The first covid-19 vaccine developed as part of Operation Warp Speed is likely to be authorized for emergency use this week in the US following an all-day meeting of federal medical advisors today, December 17.

Nine members of the US Congress have sent a letter to Google asking it to clarify the circumstances around its former ethical AI co-lead Timnit Gebru’s forced departure. Led by Representative Yvette Clarke and Senator Ron Wyden, and co-signed by Senators Elizabeth Warren and Cory Booker, the letter sends an important signal about how Congress…

Cloud computing is at a critical juncture. Millions of companies now use it to store data and run applications and services remotely. This has reduced costs and sped operations. 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. Google, the suit alleges, not only connects ad buyers and sellers; it operates the exchange and manipulates the rules and algorithms to favor…

China’s Chang’e 5 mission successfully delivered samples of lunar rock and dust to Earth on December 17. It marks the first time in 44 years that moon rocks have been brought back to our planet, since the Soviet Union’s Luna 24 mission in 1976. It’s also the first time China has ever pulled off a…

Over the past year, we’ve seen a rise in robotaxis and autonomous vehicle use. Companies such as Waymo, Cruise, and Baidu have all made strong headway as industry pioneers. In China specifically, 2020 headlines regularly featured major autonomous vehicle announcements, such as the public launch of Baidu Apollo robotaxi services in the cities of Beijing,…

On November 3, Tina Barton ran into a problem. It was Election Day in the US and Barton, a Republican, was city clerk for Rochester Hills, Michigan, a conservative-leaning community near Detroit. As her team was uploading voting results, a technical issue resulted in the double counting of some votes. The error wasn’t initially realized,…

We’re now six weeks past Election Day, and electors in every state followed the will of the voters and confirmed the victory of Joe Biden. But while the Electoral College made the results official, President Donald Trump is continuing to protest them, despite having lost dozens of court cases within the past month. In any…

By now, we’ve all heard some version of the story. On December 2, after a protracted disagreement over the release of a research paper, Google forced out its ethical AI co-lead, Timnit Gebru. The paper was on the risks of large language models, AI models trained on staggering amounts of text data, which are a…

A few times a week, Vincent Buyssens’s students in Mechelen, Belgium’s Thomas More University College get on Instagram while he’s lecturing about creative strategy. They swipe through stories, add posts to their profile, and get lost in rabbit holes. But they’re not being surreptitious about it; in fact, Buyssens requires those taking his college course…

Deep learning is an inefficient energy hog. It requires massive amounts of data and abundant computational resources, which explodes its electricity consumption. In the last few years, the overall research trend has made the problem worse. Models of gargantuan proportions—trained on billions of data points for several days—are in vogue, and likely won’t be going…

Many of the most successful and widely used machine-learning models are trained with the help of thousands of low-paid gig workers. Millions of people around the world earn money on platforms like Amazon Mechanical Turk, which allow companies and researchers to outsource small tasks to online crowdworkers. According to one estimate, more than a million people…

A genetically modified salmon will become the first GM food animal to go on sale in the US, according to its maker, AquaBounty, possibly launching an era of steaks and chops from creatures with modified DNA. In the US, a number of genetically modified animals have been approved or cleared for sale. There’s the neon…

When covid-19 began to race around the world, countries closed businesses and told people to stay home. Many thought that would be enough to stop the coronavirus. If we had paid more attention to pigs, we might have known better. When it comes to controlling airborne viruses, says Bill Christianson, “I think we fool ourselves…

A covid-19 chart that’s been shared thousands of times is dramatizing just how well vaccines against the disease can work and how we might get out of pandemic hell. Today, advisors to the US Food and Drug Administration voted in favor of emergency authorization for Pfizer’s covid-19 shot, and the data in this chart is…

I’ve often been told, “The data does not lie.” However, that has never been my experience. For me, the data nearly always lies. Google Image search results for “healthy skin” show only light-skinned women, and a query on “Black girls” still returns pornography. The CelebA face data set has labels of “big nose” and “big…

The pandemic made for a lot of differences in this year’s US elections, including vastly expanded access to mail-in ballots and early voting. That upended the Election Day rituals many Americans had become used to—but it resulted in more people voting than ever before. It also meant they voted more securely than ever. Officials around…

SpaceX today pulled off the first ever high-altitude (well, high-ish) flight of Starship, the rocket the company hopes will one day take humans to the moon and Mars. Although the spacecraft failed to make a safe landing—in fact, it exploded on impact—it’s the highest any Starship prototype has flown. Still well short of orbit, though,…

What happened: The US Federal Trade Commission has filed an antitrust lawsuit against Facebook for its “anticompetitive conduct and unfair methods of competition.” That includes its 2012 acquisition of Instagram and 2014 acquisition of WhatsApp. Facebook, the FTC alleges, has a monopoly on social networking. “Since toppling early rival MySpace and achieving monopoly power, Facebook…

The European Medicines Agency, which has been evaluating covid-19 vaccines produced by Pfizer and BioNTech, says it was hit with a cyberattack. Just days after a coronavirus vaccine from Pfizer and BioNTech was used for the first time in the UK, regulatory documents for the medicine have “been unlawfully accessed,” according to European authorities. The…

Facebook said on December 3 that it would remove posts with false claims or conspiracy theories about what’s in the covid-19 vaccines that everyone’s counting on. In the face of rumors suggesting that Bill Gates has installed tracking microchips in the shots, or that the inoculations contain luciferase, a glowing chemical from fireflies whose name…

When NASA finally gets back to the moon—probably not till sometime after 2024—it will start the groundwork for the first extraterrestrial colony in the history of human civilization, and for future missions to Mars. But America’s return for the first time since the Apollo program will also inaugurate a new era of deep-space science. A NASA…

As a reporter who can code, I can easily collect information from websites and social media accounts to find stories. All I need to do is write a few lines of code that go into the ether, open up websites, and download the data that is already publicly available on them. This process is called…

Scientists have long seen lithium-metal batteries as an ideal technology for energy storage, leveraging the lightest metal on the periodic table to deliver cells jam-packed with energy. But researchers and companies have tried and failed for decades to produce affordable, rechargeable versions that didn’t have a nasty habit of catching on fire. Then earlier this…

The news: The UK started vaccinating its population against covid-19 today, becoming the first country to start distributing the Pfizer-BioNTech vaccine, less than a week after its approval. It is being given to elder-care home workers and people over 80 first, with a 90-year-old woman named Margaret Keenan the first to receive it outside a…

Digital contact tracing apps first emerged early in the pandemic. They’d let you know if you’d been around anyone who had tested positive, and they worked on a regular personal smartphone. So far, they haven’t been a silver bullet, and they’ve faced criticism over usability, privacy, and more. But they’re low-cost tools based on technology…

The news: A capsule containing the first rock samples from the asteroid Ryugu returned to Earth on Sunday, December 6, in “perfect” condition, according to researchers. The samples were gathered after a six-year mission by the Japanese spacecraft Hayabusa-2 to and from Ryugu, which is 180 million miles away. Hayabusa-2 flew close to Earth and…
