When alumni opened the first issue of The Technology Review in January 1899, they found not only a description of MIT’s new Pierce Building but crisp photographs of its interiors as well. The second issue featured photos of the varsity football team and an alumni banquet in Chicago that looped in 130 long-distance guests by phone. Photographs continued to appear regularly, offering alumni a window into the first Tech Reunions in 1904, stunning views of the Grand Canyon in 1905, and more. In 1922, the magazine also began publishing scientific articles with accompanying photos. 1930: “A corrugated sheet of water,…

“The most challenging aspect of developing an engineering solution to prevent overdose mortality is simultaneously addressing patient adherence and willingness to adopt new technology, combating stigma, minimizing false positive detections, and ensuring the rapid delivery of antidotes,” says the paper’s lead author, Hen-Wei Huang, a former MIT visiting scientist and an assistant professor of electrical and electronic engineering at Nanyang Technological University in Singapore. “Our proposed solution tackles these unmet needs.” The researchers hope to test the device in humans within three to five years. They are now working on miniaturizing it further and optimizing the onboard battery, which currently…

In addition, the researchers found that the regeneration was due in part to activation of a cellular signaling pathway known as mTOR, which causes cells to produce more protein; this protein synthesis is essential for stem cells to proliferate. And they showed that mTOR activation led to production of large quantities of polyamines, small molecules that help cells grow and divide. Another finding, though, was that if a cancer-causing gene was turned on during the refeeding stage, the mice were much more likely to develop precancerous polyps than if the gene was turned on during the fast. Cancer-linked mutations that…

The most abundant protein in animals, collagen is fibrous, made from long strands of protein that intertwine to form a tough triple helix. “Collagen is the scaffold that holds us together,” says chemistry professor Ron Raines, the study’s senior author.  Peptide bonds are formed between a carbon atom from one amino acid and a nitrogen atom of the adjacent amino acid. The carbon atom also forms a double bond with an oxygen atom, creating a molecular structure called a carbonyl group. This carbonyl oxygen has a pair of electrons that don’t form bonds with any other atoms but can be…

How refrigeration ruined fresh food Three-quarters of everything in the average American diet passes through the cold chain—the network of warehouses, shipping containers, trucks, display cases, and domestic fridges that keep meat, milk, and more chilled on the journey from farm to fork.As consumers, we put a lot of faith in terms like “fresh” and “natural,” but artificial refrigeration has created a blind spot. We’ve gotten so good at preserving (and storing) food, that we know more about…

Before you buy orange juice, it probably waited, for as long as two years, in a two-story, stainless-steel tank filled with 265,000 gallons of viscous brown slush. It’s orange juice, but with its water and volatile flavor molecules burned off. The result is a simple syrup six times more sugary than juice and devoid of any of an orange’s fruity, floral zing. Bananas? They may not be chilled in the grocery store, but they’re the ultimate refrigerated fruit. It’s only thanks to what Nicola Twilley calls “a seamless network of thermal control” that they’re able to be a global commodity…

The demand for new and improved infrastructure across the world is not being met. The Asian Development Bank has estimated that in Asia alone, roughly $1.7 trillion needs to be invested annually through to 2030 just to sustain economic growth and offset the effects of climate change. Globally, that figure has been put at $15 trillion. In the US, for example, it is no secret that the country’s highways, railways and bridges are in need of updating. But similar to many other sectors, there are significant shortages in skilled workers and resources, which delays all-important repairs and maintenance and harms…

A new crop of biotech startups, armed with carbon-guzzling bacteria and plenty of capital, are promising something that seems too good to be true. They say they can make food out of thin air.But that’s exactly how certain soil-dwelling bacteria work. In nature, they survive on a meager diet of oxygen, nitrogen, carbon dioxide, and water vapor drawn directly from the atmosphere. In the lab, they do the same, eating up waste carbon and reproducing so enthusiastically that their populations swell to fill massive fermentation tanks. Siphoned off and dehydrated, that bacterial biomass becomes a protein-rich powder that’s chock-full of…

Dried cells—it’s what’s for dinner. At least that’s what a new crop of biotech startups, armed with carbon-guzzling bacteria and plenty of capital, are hoping to convince us. Their claims sound too good to be true: They say they can make food out of thin air. But that’s exactly how certain soil-dwelling bacteria work. In nature, these “autotrophic” microbes survive on a meager diet of oxygen, nitrogen, carbon dioxide, and water vapor drawn directly from the atmosphere. In the lab, they do the same, eating up waste carbon and reproducing so enthusiastically that their populations swell to fill massive fermentation…

“This is simply a question of right and wrong.” “You can’t deny the costs, though. You keep saying that just one more year of taxes will solve— “We’re not solving—we’re mitigating!” “Then what’s the point?” The shrill back-and-forth fills the kitchen, where Xia is busy making breakfast, some kind of awful cricket-protein smoothie with kale. Tascha squeezes into the small space behind her, kisses her on the cheek. “Can you maybe put that in your head?” Xia doesn’t put it in her head, but she at least lowers the volume with a click of her tongue. ElectoPod’s never-ending shouting match…

 “We’re really firm believers that by contributing to the community and building upon open-source data models, the whole community moves further, faster,” says Larry Zitnick, the lead researcher for the OMat project. Zitnick says the newOMat24 model will top the Matbench Discovery leaderboard, which ranks the best machine-learning models for materials science. Its data set will also be one of the biggest available.  “Materials science is having a machine-learning revolution,” says Shyue Ping Ong, a professor of nanoengineering at the University of California, San Diego, who was not involved in the project. Previously, scientists were limited to doing very accurate…

AI could help people find common ground during deliberations Reaching a consensus in a democracy is difficult because people hold such different ideological, political, and social views.Perhaps an AI tool could help. Researchers from Google DeepMind trained a system of large language models to operate as a “caucus mediator,” generating summaries that outline a group’s areas of agreement on complex but important social or political issues.The researchers say their work highlights the potential of AI to help groups…

It may also be causing more severe disease. People with Oropouche fever typically have a sudden fever, aches and pains, and nausea. Most cases are mild, but some people have developed encephalitis and meningitis. And this year, two otherwise healthy young women who caught the virus have died. Oropouche can be passed from mother to fetus, and it has been linked to stillbirths and birth anomalies. There are no treatments. There are no vaccines, either. This week, let’s take a look at why Oropouche is spreading, and what we can do about it. Oropouche virus was first identified in 1955,…

Participants were divided up into six-person groups, with one participant in each randomly assigned to write statements on behalf of the group. This person was designated the “mediator.” In each round of deliberation, participants were presented with one statement from the human mediator and one AI-generated statement from the HM and asked which they preferred.  More than half (56%) of the time, the participants chose the AI statement. They found these statements to be of higher quality than those produced by the human mediator and tended to endorse them more strongly. After deliberating with the help of the AI mediator,…
