The Boston Globe remembers James Santoro ’23; Karenna Groff ’22, MEng ’23; her father, Michael Groff, MD an executive MBA student at MIT’s Sloan School of Management; and three others who passed away in a plane accident earlier this week. “Both Karenna and James were tremendous contributors to their sport teams, the institution, and their local communities,” says G. Anthony Grant, MIT’s director of athletics and head of the Department of Athletics, Physical Education, and Recreation, adding: “We offer our sincere condolences and grieve with the Groff and Santoro families as well as their loved ones.” E. Antonio Chiocca, a friend of the Groff family, remembers Dr.Groff as, “Just a really nice guy, great family man. Just an amazing individual.”

Researchers at MIT have concluded that AI does not develop “value systems” over time, reports Kyle Wiggers for TechCrunch. “For me, my biggest takeaway from doing all this research is to now have an understanding of models as not really being systems that have some sort of stable, coherent set of beliefs and preferences,” says graduate student Stephen Casper. “Instead, they are imitators deep down who do all sorts of confabulation and say all sorts of frivolous things.”

Berly McCoy and Sushmita Pathak of NPR’s Short Wave spotlight research by postdoctoral associate Funing Li and his team on tornado occurrence. The researchers used “historical data to model and simulate the interaction between land and the atmosphere,” explains McCoy. 

A new study by researchers at MIT and elsewhere explores “children’s exploitation of language ‘loopholes’ — instances in which kids technically do what adults ask of them but completely violate the true intent of the request,” reports Charlotte Hu for Scientific American. “Sometimes you don’t want to cooperate, but it might feel risky to outright refuse,” explains former postdoc Sophie Bridgers. “We started to be curious about the strategies [kids] used to handle this tension.” 

Graduate student Cathy Fang speaks with CBS News reporter Lindsey Reiser about her research studying the effects of AI chatbots on people’s emotional well-being. Fang explains that she and her colleagues found that how the chatbot interacts with the user is important, “but also how the user interacts with the chatbot is equally important. Both influence the user’s emotional and social well-being.” She adds: “Overall, we found that extended use is correlated with more negative outcomes.”

A new proposal by graduate student Shayne Longpre and other AI researchers suggests “a new scheme supported by AI companies that gives outsiders permission to probe their models and a way to disclose flaws publicly,” reports Will Knight for Wired. “The authors suggest three main measures to improve the third-party disclosure process: adopting standardized AI flaw reports to streamline the reporting process; for big AI firms to provide infrastructure to third-party researchers disclosing flaws; and for developing a system that allows flaws to be shared between different providers,” writes Knight. 

Writing for Fast Company, graduate student Sheng-Hung Lee and Devin Liddell of Teague highlight four types of AI technologies that could aid senior citizens in their homes. “To better understand how seniors want AIs and robots to help in their homes, we asked them,” they write.  “We recruited seniors from the MIT AgeLab’s research cohort—each around 70 years old and in the early stages of retirement—and then engaged in wide-ranging conversations about their aspirations and fears about these technologies.”

Researchers from MIT and elsewhere estimate that “while 36% of U.S. private sector jobs were technically ‘exposed’ to automation through computer vision… it would only make economic sense for firms to pursue automation for 8% of all private sector jobs—just a quarter of those jobs labelled ‘exposed,’” report François Candelon, David Zuluaga Martínez and Etienne Cavin for Fortune. 

Prof. Sara Seager, postdoctoral fellow Iaroslav Iakubivskyi and Claire Isabel Webb PhD '20 have designed Phainoterra, an imaginary planet “with a habitable sulfuric acid-based biochemistry” using “extensive scientific research and cross-checking against known physical precepts,” reports Leslie Katz for Forbes. The creation of Phainoterra is a part of “Proxima Kosmos, a new project that unites scientists, including one from NASA, with designers and sci-fi writers to create a speculative solar system consistent with the laws of astronomy and physics.” 

Postdoctoral associate Mostafa Hamouda speaks with Washington Post reporter Scott Dance about the recent cold blast that is bringing “frigid air that normally swirls above the North Pole to places much farther south.” Hamouda explains: “You need really cold air in the pole to have a very fast-spinning polar vortex.” Any warming “slows the whole circulation down.”

Former postdoctoral associate Wen Shuhao and postdoctoral fellows Ma Jian and Lai Lipeng co-founded Xtalpi, a biotech startup that “uses AI and quantum physics-based calculations to find suitable structures that are fit for drug making,” reports Zinnia Lee for Forbes. The company plans to expand their technology to other industries such as solar panels and electric vehicle batteries. 

Graduate student Palak Patel speaks with BBC News reporter Chris Baraniuk about her work designing an “experimental molten regolith electrolysis system, for extracting oxygen and metal from the lunar soil.” Palak explains: “We’re really looking at it from the standpoint of, ‘Let’s try to minimize the number of resupply missions.’” 

Graduate student Shomik Verma writes for Newsweek that “we need systemic change to ensure our individual climate actions aren't going to waste. If you're serious about fighting climate change this year, instead of recycling more, consider shifting focus to policy support and investments.” Verma adds: “if we advocate for change at the federal and state level, we can build an effective bridge between our individual actions and the change we want to see in the world.”

Physics World has selected two research advances by MIT physicists for its Top 10 Breakthroughs of the Year for 2024, reports Hamish Johnston for Physics World. Graduate student Andrew Denniston and his colleagues were honored for their work “being the first to unify two distinct descriptions of atomic nuclei,” which Johnston describes as a “major step forward in our understanding of nuclear structure and strong interactions.” MIT researchers were also featured for their work demonstrating quantum error correction on an atomic processor with 48 logical qubits, making it “far more likely that quantum computers will become practical problem-solving machines.”

Graduate student William Parker SM '22 has discovered that two geomagnetic storms have “affected the orbits of thousands of satellites, resulting in an unprecedented mass migration,” reports Passant Rabie for Gizmodo. “Geomagnetic storms are disturbances in Earth’s magnetosphere—a large bubble of magnetic field around our planet—caused by solar wind,” explains Rabie.
