Researchers at MIT have developed magnetic transistors, “which could enable faster and more energy-efficient semiconductors,” reports Alex Knapp for Forbes. “Researchers have been trying to use magnets this way for years, but the materials used so far haven’t been optimal for computing functions,” explains Knapp. “That changed after experimenting with chromium sulfur bromide, which replaces the silicon in a conventional microchip and enables the transistors to be switched on and off with an electric current.” 

Researchers at MIT have found that up to 98% of the energy produced by an earthquake dissipates as heat, reports Stephanie Pappas for Scientific American, who notes that the findings could be used to help create better earthquake forecasts. The researchers “created itty-bitty lab earthquakes by pressing centimeter-sized wafers of a powdered granite and magnetic particle mixture between aluminum pistons until the wafers slipped or snapped,” explains Pappas. “They measured this process of cracking under stress with thermometers and piezoelectric sensors that mimic the seismographs used to measure real earthquakes.” 

Researchers at MIT have created “a series of miniature, controlled versions of real earthquakes to see where all that destructive energy actually goes and what it’s doing,” reports Luis Prada for Vice. “The goal of the research is to isolate the key physical processes that underlie every earthquake,” explains Prada. “The hope is that any knowledge gained will help refine earthquake prediction models and possibly even pinpoint which regions are sitting on fault lines ready to pop.” 

Using the James Webb Telescope, researchers at MIT and elsewhere are studying the potential presence of “an Earth-like atmosphere on an exoplanet for the first time,” reports Jacopo Prisco for CNN. “The planet is part of a planetary system about 40 light-years away from Earth called TRAPPIST-1,” explains Prisco. 

Edwin Chen '08 speaks with Forbes reporter Pheobe Liu about his journey to founding Surge AI, a startup that “helps tech companies get the high-quality data they need to improve their AI models.” 

Gizmodo reporter Gayoung Lee writes that MIT researchers created “lab quakes” or miniature versions of earthquakes in a controlled setting and found that “anywhere between 68 and 98% of the energy goes into generating heat around a quake’s epicenter.” The findings “could help inform the creation of a physical model for earthquake dynamics or seismologists’ efforts to pick out regions most vulnerable to earthquakes.”

Boston Globe reporter Jon Chesto spotlights the kickoff event for the new MIT-GE Vernova Energy and Climate Alliance, which will “fund research initiatives, fellowships, and other programs with an eye toward improving energy technologies and decarbonization.” GE Vernova CEO Scott Strazik emphasized that he has been impressed with the passion and talent for clean-tech among the students at MIT and other universities. “I started these discussions with the objective that we should inspire future leaders to come into our industry and ideally come to our company,” Strazik said. “They’ve probably inspired us more than we’ve inspired them.”

Prof. Nergis Mavalvala, dean of the MIT School of Science, joins Bob McDonald of CBC’s “Quirks & Quarks” to discuss how 10 years after LIGO’s first detection of gravitational waves the observatories are still “helping scientists better understand the life cycles of stars, the nature of gravity, and transforming the way we explore the farthest reaches of space.” Mavalvala shares: "Scientists have been able to design and construct these instruments that are capable of measuring imperceptibly small changes in spacetime distance, and in the past 10 years the sensitivity of these instruments has improved. That’s what is allowing us to make greater discoveries.” 

Prof. Richard Binzel spoke at the Europlanet Science Congress (EPSC) about efforts to create a system that could help deflect deadly asteroids away from Earth, reports Alex Wilkins for New Scientist. “If we had to deal with an actual asteroid threat,” says Binzel, “we would certainly want to know these properties, like the spin or tumbling state [of an asteroid].”

Writing for The New York Times, Dennis Overbye celebrates the 10-year anniversary of LIGO’s first direct detection of gravitational waves, underscoring how LIGO has advanced our understanding of the universe’s cosmic history. The first detection was a discovery that “changed astrophysics, opening a window onto previously inaccessible realms of nature in which space could rip, bend, puff up, crumple and even vanish,” writes Overbye. The late Prof. Emeritus Rainer Weiss, who dreamed up the idea for LIGO, said of LIGO’s first detection in September 2015: “It was waving hello. It was amazing. The signal was so big, I didn’t believe it.”

The Cambridge Science Carnival, founded by the MIT Museum, will take place on September 21, 2025, in the Kendall/MIT Open Space, reports The Boston Globe. The event features “more than 100 booths with science and art based activities and demonstrations,” writes The Boston Globe. From a STEAM-themed playground to “live, interactive music from the MIT physics departments,” kids are welcome to play, learn and enjoy. 

Forbes reporter Martina Castellanos spotlights Edwin Chen '08, founder of Surge AI, as one of the 10 youngest billionaires on the 2025 Forbes 400 list. After working in machine learning, Chen saw “the lack of quality training data for AI,” and “launched Surge AI in 2020 to fix the problem,” writes Castellanos. 

Writing for Nature, Bruce Allen pays tribute to Prof. Emeritus Rainer Weiss, a pioneering physicist who “spearheaded the construction of the LIGO observatory to detect Einstein’s predicted ripples in space-time [and] leaves a legacy of persistence and mentorship.” Allen recalls how, decades earlier, Weiss rejoiced in a moment of discovery with him. “This is why we do science,” Weiss said. “Not for prizes or awards — that’s all nonsense. It’s for the satisfaction when something you’ve struggled with finally works.” Weiss, Allen emphasizes, was “a scientist driven by curiosity, persistence and the joy of understanding how the Universe works.”

Researchers at MIT have developed the first full map of the quantum landscape that constrains how electrons move inside matter, reports Karmela Padavic-Callaghan for New Scientist. The map “offers a new way to understand and design materials, perhaps leading to, for instance, super-efficient wires that conduct electricity with no resistance,” Padavic-Callaghan explains. “A new view of what actually happens inside materials is bound to lead to new ways to improve them.” 

David Baltimore, a former Institute Professor at MIT and a Nobel laureate, has passed at the age of 87, reports Gina Kolata for The New York Times. Baltimore’s work rocked “the foundation of the fledging field of molecular biology,” writes Kolata. His “Nobel-winning discovery [upended] what was called the central dogma, which stated that information in cells flowed in only one direction — from DNA to RNA to the synthesis of proteins. Dr. Baltimore showed that information can also flow in the reverse direction, from RNA to DNA.”
