Using the James Webb Space Telescope (JWST), MIT astronomers have spotted “small space rocks – including some just dozens of feet in length, the tiniest ever discovered in our solar system’s main asteroid belt between Mars and Jupiter,” reports Robin George Andrews for National Geographic. “This work helps to fill in astronomers’ understanding of the asteroid belt, the wreckage left behind from the inner solar system’s formation—and it’s always nice to spy more of those rocky time capsules for future study,” explains Andrews. 

Forbes reporter Joe McKendrick spotlights a study by researchers from the MIT Center for Collective Intelligence evaluating “the performance of humans alone, AI alone, and combinations of both.” The researchers found that “human–AI systems do not necessarily achieve better results than the best of humans or AI alone,” explains graduate student Michelle Vaccaro and her colleagues. “Challenges such as communication barriers, trust issues, ethical concerns and the need for effective coordination between humans and AI systems can hinder the collaborative process.”

Commonwealth Fusion Systems, an MIT spinoff, plans to build “the nation’s first grid-scale fusion power plant in Virginia by the early 2030s,” reports Laura Vozzella and Gregory S. Schneider for The Washington Post. “Fusion is a long-sought source of power that can generate almost limitless energy by combining atomic nuclei,” they write. “It is unlike fission, the more common form of nuclear energy, in which the nucleus is split, and which generates large amounts of radioactive waste.” 

New York Times reporter Thomas B. Edsall spotlights research by Prof. David Autor examining how socioeconomic status influences the gender gap. The researchers noted that the “explanation lies in the disproportionate share of boys ranked at or near the bottom on measures of academic performance and behavior — what statisticians call the left tail or lower tail of the distribution,” writes Edsall.

MIT spinoff Commonwealth Fusion Systems has shared their plans “to build its first commercial power plant” in Virginia, reports Aaron Pressman for The Boston Globe. “Commonwealth aims to build a complete power plant with a fusion machine generating heat used to spin turbines and make 400 megawatts of electric power, enough to supply 150,000 homes, by the mid-2030s,” explains Pressman. 

Commonwealth Fusion Systems, an MIT spinout, has announced plans to “build its first fusion power plant in Virginia, with the aim of generating zero-emissions electricity there in the early 2030s,” reports Raymond Zhong for The New York Times. “The proposed facility is among the first to be announced that would harness nuclear fusion, the process that powers the sun, to produce power commercially, a long-elusive goal that scientists have pursued for the better part of a century,” explains Zhong. 

MIT spinout Commonwealth Fusion Systems has announced plans to build the “world’s first grid-scale fusion power plant in Virginia, to generate power by the early 2030s,” reports Timothy Gardner for Reuters. The project, “could revolutionize the global energy industry by tapping into a virtually limitless power source, similar to that which fuels the stars,” writes Gardner. 

Researchers at MIT and the Center for Strategic and International Studies have used a tabletop exercise to determine whether a further build-up of US nuclear capabilities would impact China’s nuclear weapon use in Taiwan, reports Kathrin Hille for Financial Times. “The US has 600-plus tactical nuclear weapons, and it is modernizing their delivery means,” explains Principal Research Scientist Eric Heginbotham. “In the game, the one US team that employed tactical nuclear weapons used fewer than a dozen. In no cases did any of the participants ever say: ‘We need SLCM-N or some other system that is not in the inventory or being deployed under the current modernization plan.’”

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.”

A new study by researchers at MIT and elsewhere has found that “87% of people say employees in their organization are confused to a certain degree about where to turn for data and tech services and issues,” reports Rachel Curry for CNBC. “Most of the organizations whose leaders responded to the survey had multiple executive roles in the tech and data spaces,” explains Curry. 

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. 

Prof. Giovanni Traverso speaks with GBH’s “All Things Considered” host Arun Rath about his work developing new approaches to weight loss treatments that don’t involve surgery or pharmaceuticals. “Our team does a lot of work on ingestible systems, ingestible capsules that can do many things,” says Traverso. “You know, we recognize that we live now in a world where we have really incredible therapies that are very effective for the treatment of diabetes and obesity. But we also recognize that they’re not for everybody. There are people who have side effects, people who can’t take them, so these are certainly alternatives, or potentially synergistic interventions, that could work together either with those drugs or, as I was mentioning, for folks that have side effects from the drugs.”

New research by graduate student William Parker SM '22 has found that two geomagnetic storms have led to the mass migrations of thousands of satellites in low Earth orbit, reports Jeff Foust for Space News. “This is a significant impact,” says Parker. “This is critical infrastructure to all of our space operations moving forward, and it will only become more important as time goes on.”

Joseph Coughlin, director of the MIT AgeLab, shares the importance of having conversations about intergenerational family wealth transfers to help avoid disputes in inheritances plans, report Anne Tergesen and Dalvin Brown for The Wall Street Journal. "The only way to avoid causing stress, surprise or anger to people is to have these discussions gradually over time," says Coughlin.

MIT scientists have discovered the smallest asteroids known to exist in the Main Asteroid Belt between Mars and Jupiter, reports Alfredo Carpineti for IFL Science. “The team of researchers behind this new discovery cleverly reused images from the search for exoplanets,” writes Carpineti. “Stacks of images looking at the same distant star field were used with a technique called “shift and stack”, which aims to highlight possible movement in the foreground, like from an asteroid. They were able to find 138 asteroids in the decameter size range.”
