Researchers at MIT have “developed a new technique that enables large language models to learn new skills and knowledge without forgetting their past capabilities,” reports Ben Dickson for Venture Beat. “Their technique, called self-distillation fine-tuning (SDFT), allows models to learn directly from demonstrations and their own experiments by leveraging the inherent in-context learning abilities of modern LLMs,” explains Dickson. “Experiments show that SDFT consistently outperforms traditional supervised fine-tuning (SFT) while addressing the limitations of reinforcement learning algorithms.” 

MIT President Sally Kornbluth joined Jim Braude and Margery Eagan live in studio for GBH’s Boston Public Radio to discuss MIT, the pressures facing America’s research enterprise, the importance of science and more. 

Prof. Joshua Bennett speaks with NPR host Michel Martin about his new book “The People Can Fly: American Promise, Black Prodigies, and the Greatest Miracle of All Time.” The book “weaves together folklore, history and memoir to sort through what it means to be a prodigy, especially a Black prodigy,” explains Martin. Bennett cites fatherhood and his mother’s ideals as his inspiration for the book: “In becoming a father who's raising my children in a very different context in suburban Massachusetts and not in the Bronx and in South Yonkers and having very different experiences than my parents did… I just started to think, what's the full breadth of what I've inherited around this idea of what it means to pursue an education? And that's really what inspired it.” 

Senior Research Scientist Leo Anthony Celi speaks with New York Times reporter Gina Kolata about the use of AI in health care. “The real concern isn’t AI itself,” says Celi. “It’s the AI is being deployed to optimize a profoundly broken system rather than to reimagine it.” 

Researchers at MIT have developed a wearable breast cancer ultrasound device that could be used to detect breast cancer earlier, reports Amerigo Allegretto for AuntMinnie.com. “The device can image as deep as 15 cm into breast tissue and can image the entire breast from two or three locations,” explains Allegretto. “The team described the technology as an end-to-end system ultrasound architecture consisting of a novel sparse array geometry and a codesigned data acquisition system.” 

Surface reporter David Graver highlights “Lighten Up! On Biology and Time,” an MIT Museum exhibit exploring the “connection between living creatures and circadian rhythm through 18 contemporary artworks and experiential environments.” "The ‘Lighten Up!’ exhibition begins with awakening and ends with sleep,” says MIT Museum Director Michael John Gorman. “It is a whole-body experience and rewards those who take the time to linger.” 

Prof. John Urschel – a former offensive lineman for the Baltimore Ravens – joined Edgar B. Herwick III, host of GBH’s newest show, The Curiosity Desk, to talk about his love of his family, linear algebra, and football. On how he eventually chose math over football, Urschel quips: “Well, I hate to break it to you, I like math better… let me tell you, when I started my PhD at MIT, I just fell in love with the place. I fell in love with this idea of being in this environment [where] everyone loves math, everyone wants to learn. I was just constantly excited every day showing up.”

The torch for this year’s Winter Olympics was designed by Prof. Carlo Ratti, reports Laura Baisas for Popular Science. Dubbed “Essential,” the torch clocks in at just under 2.5 pounds, and "boasts a unique internal mechanism that can be seen through a vertical opening along its side. This means that audiences can peek inside and see the burner in action. From a design perspective, that reinforces Ratti’s desire to keep the emphasis on the flame itself and not the object.”

MIT AgeLab Research Scientist Lisa D’Ambrosio speaks with Parade reporter Chrissy Callahan about in-home and online safety tips for seniors living alone. “Don’t feel pressured to act on something or to make a decision quickly in response to a telephone call or a text message from someone you do not know personally,” explains D’Ambrosio. “Fraudsters and scammers often try to use time pressure to get people to do things or make choices they would not make if they had a little bit more time to consider their actions and choices. Talk to a family member, talk to a friend, talk to your partner – get another perspective.” 

Ahead of Superbowl Sunday, Forbes reporter Sandy Carter highlights a study by MIT researchers that identifies the factors needed to make an effective team. “What they found challenged many assumptions,” explains Carter. “First, team intelligence wasn’t about average IQ or brilliance of the smartest person in the room. It depended on three factors: How socially attuned the team members were to one another, whether conversations were shared rather than dominated by a few voices, and the presence of women in the group.”

Prof. Marzyeh Ghassemi and Monica Agrawal PhD '23 speak with Boston Globe reporter Hiawatha Bray about the risks on relying solely on AI for medical information. “What I’m really, really worried about is economically disadvantaged communities,” says Ghassemi. “You might not have access to a health care professional who you can quickly call and say, ‘Hey… Should I listen to this?’”  

Prof. Olivier de Weck speaks with Forbes reporter Alex Knapp about the challenges and opportunities posed by building data centers in space. Data centers are “physically secure from intrusion and environmentally friendly once operational,” says de Weck. “Essentially, the three primary resources required on Earth—land, power, and cooling—are available ‘for free’ in space after the initial launch and deployment costs are covered.”

A new study by MIT physicists demonstrates that quark-gluon plasma behaves like a liquid, findings that could shed more light on the makeup of the early universe, reports Gayoung Lee for Gizmodo. “The researchers anticipate that the methods of the new study will greatly advance our understanding of matter in the early universe,” explains Lee.
