Nature

MIT scientists have created a high-resolution brain map of the neurons that encode the meanings of various words, reports Sara Reardon for Nature. “The results hint that, across individuals, the brain uses the same standard categories to classify words,” Reardon explains, “helping us to turn sound into sense.” 

The Washington Post

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. 

STAT

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. 

The Economist

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.”  

Financial Times

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.  

The Boston Globe

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.

The New York Times

Prof. Evelina Fedorenko has uncovered evidence that the human brain uses language for communicating, not reasoning, writes Carl Zimmer for The New York Times. “Other regions in the brain are working really hard when you’re doing all these forms of thinking, but it became clear that none of those things seem to engage language circuits,” she says. 

BBC News

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.” 

Forbes

Prof. Sara Seager, Prof. Robert Langer and Prof. Nancy Kanwisher have been awarded the 2024 Kavli Prize for their work in the three award categories: astrophysics, nanoscience, and neuroscience, respectively, reports Michael T. Nietzel for Forbes. According to the Norwegian Academy of Science and Letters, this award honors scientists with outstanding research “that has broadened our understanding of the big, the small and the complex,” writes Nietzel. 

Correio Braziliense

Reporting in Portuguese, Correio Braziliense highlights researchers at MIT who have developed a new technique that uses light stimuli to benefit people with paralysis or amputations. “Our work could help bring the use of optogenetics closer to humans in the realm of neuroprosthetics that control paralyzed muscles and other functions of the peripheral nervous system,” says graduate student Guillermo Herrera-Arcos. 

CBS

Ara Mahar, a technical associate at the McGovern Institute, speaks with CBS News about what inspired their interest in kimonos – a traditional Japanese garment. “Mahar became so enamored [with the kimono] they moved to Japan to formally study it in 2016,” explains CBS. “Mahar became an expert, and moved back to Boston two years later. Mahar now gives demonstrations and lectures throughout the area.” 

The Economist

Research Scientist Robert Ajemian, graduate student Greta Tuckute and MIT Museum Exhibit Content and Experience Developer Lindsay Bartholomew appear on The Economist’s Babbage podcast to discuss the development of generative AI. “The way that current AI works, whether it is object recognition or large language models, it’s trained on tons and tons and tons of data and what it’s essentially doing is comparing something it’s seen before to something it’s seeing now,” says Ajemian.  

The Economist

Research Scientists Karthik Srinivasan and Robert Ajemian speak with The Economist’s Babbage podcast about the role of big data and specialized computer chips in the development of artificial intelligence. “I think right now, actually, the goal should be just to harness big data as much as we can,” says Ajemian. “It’s kind of this new tool, a new toy, that humanity has to play with and obviously we have to play with it responsibly. The architectures that they built today are not that different than the ones that were built in the 60s and the 70s and the 80s. The difference is back then they did not have big data and tremendous compute." 

Reuters

Will Dunham at Reuters writes about new research from Prof. Evelina Fedorenko and others, which found that polyglots “who spoke between five and 54 languages” used less brain activity when processing their native language. "We think this is because when you process a language that you know well, you can engage the full suite of linguistic operations - the operations that the language system in your brain supports," says Fedorenko.

Boston.com

Prof. Feng Zhang has been named to STAT’s 2024 STATUS List, which highlights the leaders shaping the future of health and life sciences, reports Dialynn Dwyer for Boston.com. “Among the companies he’s co-founded is Editas Medicine, which as of late 2023 was now the official holder of patent rights to the CRISPR-Cas9 gene editing tool used in the sickle cell therapy Casgevy, and Aera Therapeutics, which in February 2023 raised $193 million in venture funding to develop protein nanoparticles as a way of delivering gene editing,” Dwyer writes.
