A new surgical procedure and neuroprosthetic interface developed by MIT researchers allows people with amputations to control their prosthetic limbs with their brains, “a significant scientific advance that allows for a smoother gait and enhanced ability to navigate obstacles,” reports Lizette Ortega for The Washington Post. “We’re starting to get a glimpse of this glorious future wherein a person can lose a major part of their body, and there’s technology available to reconstruct that aspect of their body to full functionality,” explains Prof. Hugh Herr. 

Researchers at MIT have developed a novel surgical technique that could “dramatically improve walking for people with below-the-knee amputations and help them better control their prosthetics,” reports Timmy Broderick for STAT. “With our patients, even though their limb is made of titanium and silicone, all these various electromechanical components, the limb feels natural, and it moves naturally, without even conscious thought," explains Prof. Hugh Herr. 

Using a new surgical technique, MIT researchers have developed a bionic leg that can be controlled by the body’s own nervous system, reports The Economist. The surgical technique “involved stitching together the ends of two sets of leg muscles in the remaining part of the participants’ legs,” explains The Economist. “Each of these new connections forms a so-called agonist-antagonist myoneural interface, or AMI. This in effect replicates the mechanisms necessary for movement as well as the perception of the limb’s position in space. Traditional amputations, in contrast, create no such pairings.”  

A new surgical approach developed by MIT researchers enables a bionic leg driven by the body’s nervous system to restore a natural walking gait more effectively than other prosthetic limbs, reports Clive Cookson for the Financial Times. “The approach we’re taking is trying to comprehensively connect the brain of the human to the electro-mechanics,” explains Prof. Hugh Herr.  

Researchers at MIT and Brigham and Women’s Hospital have created a new surgical technique and neuroprosthetic interface for amputees that allows a natural walking gait driven by the body’s own nervous system, reports Adam Piore for The Boston Globe. “We found a marked improvement in each patient’s ability to walk at normal levels of speed, to maneuver obstacles, as well as to walk up and down steps and slopes," explains Prof. Hugh Herr. “I feel like I have my leg — like my leg hasn’t been amputated,” shares Amy Pietrafitta, a participant in the clinical trial testing the new approach.

MIT scientists have conducted a trial of a brain controlled bionic limb that improves gait, stability and speed over a traditional prosthetic, reports Hannah Devlin for The Guardian. Prof. Hugh Herr says with natural leg connections preserved, patients are more likely to feel the prosthetic as a natural part of their body. “When the person can directly control and feel the movement of the prosthesis it becomes truly part of the person’s anatomy,” Herr explains. 

Prof. Hugh Herr joins the BBC’s Shiona McCallum to discuss a program by the K. Lisa Yang Center for Bionics aimed at bringing prosthetics to those who suffered forced amputations during the Sierra Leone Civil War. “When we train a young person on how to construct an arm or leg prothesis we’ve impacted the country for solidly forty years,” Herr says. “That person’s going to be living in that country and contributing to their community for a very long time. That’s exciting.” 

David Zipper, a senior fellow at the MIT Mobility Lab, writes for Bloomberg about how the findings of William Whyte, an urbanist observer and writer, on what attracts people to urban spaces could be used to help draw people back to downtown areas after the Covid-19 pandemic. “Whyte’s insights suggest a need to build comfortable, pleasant places that invite people to linger, perhaps eating a meal or buying a new shirt while they’re there,” writes Zipper. “And his research serves as a reminder that good public spaces strengthen human relationships, offering an antidote to the loneliness epidemic said to afflict a growing number of Americans.”

Prof. Skylar Tibbits speaks with Tech Briefs reporter Andrew Corselli about his team’s work developing a new “additive manufacturing technique that can print rapidly with liquid metal, producing large-scale parts like table legs and chair frames in a matter of minutes.” Of his advice for engineers aiming to bring their ideas to fruition, Tibbits emphasizes: “Work hard, fail a lot, keep trying, don’t give up, and have amazing people around you. We're a research lab, so our whole goal is to go from impossible to possible. So, we're allowed to fail; we're not limited by profitability or customer demand or economy.”

New York Times Style Magazine reporter Susan Dominus spotlights the “maximalist, category-defying work” of MIT Prof. Emerita Joan Jonas, who is being honored with a retrospective at the MoMA. “Perception is something that really is an important part of my thinking,” Jonas explains. “How does the audience perceive my work? How does my work change their perception?” Michael Rakowitz SMVisS ’98 notes that Jonas, “is a foundational and transformative figure not just in the realm of video and performance and feminist art but in art that moves away from anthropocentrism.”

Prof. Nathaniel Hendren and Prof. Justin Steil speak with New York Times reporter Jason DeParle about the difficulty in building affordable housing in opportunity-rich neighborhoods. “A lot has changed in American life over the past 50 years, but the hostility to affordable housing has remained surprisingly durable,” Steil explains. “Where you grow up matters a great deal for shaping your life outcomes,” Hendren adds.

David Zipper, a senior fellow at the MIT Mobility Initiative, speaks with Kai Ryssdal of Marketplace about how cars in the U.S. are getting heavier and larger, and the environmental and safety costs associated with larger vehicles. “For decades, people who buy enormous, very heavy cars have been creating societal costs that they aren’t paying for. That’s what’s called a market failure,” said Zipper. “So if you want the market for automobiles to succeed, we need to make sure that when people are shopping for their next car, they are considering the societal costs of their purchase.”

Writing for The New York Times, Prof. Carlo Ratti and Harvard Prof. Edward L. Glaeser make the case that “the Bay Area needs a lot more housing, and we may need privately built cities to get there.” Ratti and Glaeser note, “building in the Bay Area will enable America to continue its history of allowing people to relocate to more productive places.”

Writing for The Boston Globe, Prof. Mitchel Resnick explores how a new coding app developed by researchers from the Lifelong Kindergarten group is aimed at allowing young people to use mobile phones to create interactive stories, games and animations. Resnick makes the case that with “appropriate apps and support, mobile phones can provide opportunities for young people to imagine, create, and share projects.”

Writing for The Boston Globe, MIT Prof. Carlo Ratti and Harvard Prof. Antoine Picon examine AI and the future of cities, noting that their research has shown “once trained, visual AI is shockingly accurate at predicting property values, crime rates, and even public health outcomes — just by analyzing photos.” They add: “Tireless, penetrating artificial eyes are coming to our streets, promising to show us things we have never seen before. They will be incredible tools to guide us — but only if we keep our own eyes open.”
