New bioadhesive strategy can prevent fibrous encapsulation...
Peripheral nerves — the network connecting the brain, spinal cord, and central nervous system to the rest of the body — transmit sensory information, control muscle movements, and regulate automatic bodily functions. Bioelectronic devices implanted on these nerves offer remarkable potential for the treatment and rehabilitation of neurological and systemic diseases. However, because the body perceives these implants as foreign objects, they often trigger the formation of dense fibrotic tissue at bioelectronic device–tissue interfaces, which can significantly compromise device...

Noninvasive imaging could replace finger pricks for...
A noninvasive method for measuring blood glucose levels, developed at MIT, could save diabetes patients from having to prick their fingers several times a day. The MIT team used Raman spectroscopy — a technique that reveals the chemical composition of tissues by shining near-infrared or visible light on them — to develop a shoebox-sized device that can measure blood glucose levels without any needles. In tests in a healthy volunteer, the researchers found that the measurements from their device were similar...

MIT chemists synthesize a fungal compound that...
For the first time, MIT chemists have synthesized a fungal compound known as verticillin A, which was discovered more than 50 years ago and has shown potential as an anticancer agent. The compound has a complex structure that made it more difficult to synthesize than related compounds, even though it differed by only a couple of atoms. “We have a much better appreciation for how those subtle structural changes can significantly increase the synthetic challenge,” says Mohammad Movassaghi, an...

New control system teaches soft robots the...
Imagine having a continuum soft robotic arm bend around a bunch of grapes or broccoli, adjusting its grip in real time as it lifts the object. Unlike traditional rigid robots that generally aim to avoid contact with the environment as much as possible and stay far away from humans for safety reasons, this arm senses subtle forces, stretching and flexing in ways that mimic more of the compliance of a human hand. Its every motion is calculated to avoid...

Inaugural UROP mixer draws hundreds of students...
More than 600 undergraduate students crowded into the Stratton Student Center on Oct. 28, for MIT’s first-ever Institute-wide Undergraduate Research Opportunities Program (UROP) mixer. “At MIT, we believe in the transformative power of learning by doing, and there’s no better example than UROP,” says MIT President Sally Kornbluth, who attended the mixer with Provost Anantha Chandrakasan and Chancellor Melissa Nobles. “The energy at the inaugural UROP mixer was exhilarating, and I’m delighted that students now have this easy way...

MIT Sea Grant students explore the intersection...
Norway is the world’s largest producer of farmed Atlantic salmon and a top exporter of seafood, while the United States remains the largest importer of these products, according to the Food and Agriculture Organization. Two MIT students recently traveled to Trondheim, Norway to explore the cutting-edge technologies being developed and deployed in offshore aquaculture.  Beckett Devoe, a senior in artificial intelligence and decision-making, and Tony Tang, a junior in mechanical engineering, first worked with MIT Sea Grant through the...

Driving American battery innovation forward
Advancements in battery innovation are transforming both mobility and energy systems alike, according to Kurt Kelty, vice president of battery, propulsion, and sustainability at General Motors (GM). At the MIT Energy Initiative (MITEI) Fall Colloquium, Kelty explored how GM is bringing next-generation battery technologies from lab to commercialization, driving American battery innovation forward. The colloquium is part of the ongoing MITEI Presents: Advancing the Energy Transition speaker series. At GM, Kelty’s team is primarily focused on three things: first,...

Exploring how AI will shape the future...
“MIT hasn’t just prepared me for the future of work — it’s pushed me to study it. As AI systems become more capable, more of our online activity will be carried out by artificial agents. That raises big questions: How should we design these systems to understand our preferences? What happens when AI begins making many of our decisions?” These are some of the questions MIT Sloan School of Management PhD candidate Benjamin Manning is researching. Part of his...

Artificial tendons give muscle-powered robots a boost
Our muscles are nature’s actuators. The sinewy tissue is what generates the forces that make our bodies move. In recent years, engineers have used real muscle tissue to actuate “biohybrid robots” made from both living tissue and synthetic parts. By pairing lab-grown muscles with synthetic skeletons, researchers are engineering a menagerie of muscle-powered crawlers, walkers, swimmers, and grippers. But for the most part, these designs are limited in the amount of motion and power they can produce. Now, MIT...

A War on Facts About Thanksgiving Dinner
There’s a fairy tale about Thanksgiving that gets refuted every fall. Does eating turkey really make you fall asleep? When science writers check in with the experts, they always get the same response: No, no, no, and no. Also no and no. These holiday debunkers tell you what the science says: Turkey meat is not a sedative. They tell you what the studies show: Drumsticks don’t produce fatigue. And then they take another step, however ill-advised: They lay out...

Researchers discover a shortcoming that makes LLMs...
Large language models (LLMs) sometimes learn the wrong lessons, according to an MIT study. Rather than answering a query based on domain knowledge, an LLM could respond by leveraging grammatical patterns it learned during training. This can cause a model to fail unexpectedly when deployed on new tasks. The researchers found that models can mistakenly link certain sentence patterns to specific topics, so an LLM might give a convincing answer by recognizing familiar phrasing instead of understanding the question....

MIT scientists debut a generative AI model...
More than 300 people across academia and industry spilled into an auditorium to attend a BoltzGen seminar on Thursday, Oct. 30, hosted by the Abdul Latif Jameel Clinic for Machine Learning in Health (MIT Jameel Clinic). Headlining the event was MIT PhD student and BoltzGen’s first author Hannes Stärk, who had announced BoltzGen just a few days prior. Building upon Boltz-2, an open-source biomolecular structure prediction model predicting protein binding affinity that made waves over the summer, BoltzGen (officially released on Sunday, Oct....

Celebrating the advancement of technology leadership through...
In 1965, after completing his PhD in civil engineering at MIT, Professor Richard de Neufville joined the first class of White House Fellows, one of the nation’s most prestigious programs for leadership and public service, through which he spent an intensive year working full-time at the highest levels of government. Soon after, de Neufville joined the MIT faculty and led a steering committee that developed what would become the MIT Technology and Policy Program (TPP). TPP was approved in...

Mind, hand, and harvest
On a sunny, warm Sunday MIT students, staff, and faculty spread out across the fields of Hannan Healthy Foods in Lincoln, Massachusetts. Some of these volunteers pluck tomatoes from their vines in a patch a few hundred feet from the cars whizzing by on Route 117. Others squat in the shade cast by the greenhouse to snip chives. Still others slice heads of Napa cabbage from their roots in a bed nearer the woods. Everything being harvested today will wind...

Unlocking ammonia as a fuel source for...
At a high level, ammonia seems like a dream fuel: It’s carbon-free, energy-dense, and easier to move and store than hydrogen. Ammonia is also already manufactured and transported at scale, meaning it could transform energy systems using existing infrastructure. But burning ammonia creates dangerous nitrous oxides, and splitting ammonia molecules to create hydrogen fuel typically requires lots of energy and specialized engines. The startup Amogy, founded by four MIT alumni, believes it has the technology to finally unlock ammonia...
