MIT spinoff Electrified Thermal Solutions is developing electrically charged bricks that generate and store heat as part of an effort to one day replace fossil fuels, reports Phil McKenna for Inside Climate News. “If you are running an industrial plant where you’re making cement or steel or glass or ceramics or chemicals or even food or beverage products, you burn a lot of fossil fuels,” explains Daniel Stack SM '17, PhD '21, chief executive of Electrified Thermal Solutions. “Our mission is to decarbonize industry with electrified heat.”

Current AI models require enormous resources and often provide unpredictable results. But graduate student Ziming Liu and colleagues have developed an approach that surpasses current neural networks in many respects, reports Manion Bischoff for Scientific American. “So-called Kolmogorov-Arnold networks (KANs) can master a wide range of tasks much more efficiently and solve scientific problems better than previous approaches,” Bischoff explains.

Financial Times reporter Robin Wigglesworth spotlights Prof. Daron Acemoglu’s new research that predicts relatively modest productivity growth from AI advances. On generative AI specifically, Acemoglu believes that gains will remain elusive unless industry reorients “in order to focus on reliable information that can increase the marginal productivity of different kinds of workers, rather than prioritizing the development of general human-like conversational tools,” he says.

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.” 

Researchers at MIT and elsewhere have found that the sun’s magnetic field “could form much closer to the star’s surface than previously thought,” reports Will Sullivan for Smithsonian Magazine. “The findings could help improve forecasts of solar activity that can affect satellites, power grids and communications systems on Earth—and produce magnificent auroras,” explains Sullivan. 

Senior Research Scientist C. Adam Schlosser, deputy director of the MIT Joint Program on the Science and Policy of Global Change, speaks with Joshua Miller of The Boston Globe about the 11th consecutive month of record high global temperatures and the overall pace of climate change. The rising temperatures fall “very consistently with what the science is telling us about human interference with climate,” Schlosser explains. 

Prof. David Autor is a guest of Meghna Chakrabarti on WBUR’s On Point, discussing his research on the potential impact of AI on the workforce. Autor says “AI is a tool that can enable more people with the right foundational training and judgment to do more valuable work.”

Astronomers at MIT and elsewhere have determined how to measure the spin of a nearby supermassive black hole using a new calculation method, reports Isaac Schultz for Gizmodo. The team “managed to deduce a supermassive black hole’s spin by measuring the wobble of its accretion disk after a star has been disrupted—a polite word for torn up—by the gigantic object,” explains Schultz. “They found the black hole’s spin was less than 25% the speed of light—slow, at least for a black hole.” 

Called the “Frank Lloyd Wright of computers,” technology visionary C. Gordon Bell ’57, SM '57, “the master architect in the effort to create smaller, affordable, interactive computers that could be clustered into a network,” has died. “He was among a handful of influential engineers whose designs formed the vital bridge between the room-size models of the mainframe era and the advent of the personal computer,” notes Glenn Rifkin for The New York Times.
