Prof. Catherine Wolfram speaks with Politico reporter James Bikales about the price of oil and gasoline in the United States. “Economists talk about what’s called rockets and feathers — that gas prices go up like rockets when oil prices go up, but then if oil prices go back down … they go back down like feathers,” says Wolfram. “Especially if you’re coming into the period when [gas prices] tend to rise because of summer driving, they might just stay high, even if oil prices go back down.”

Prof. Christopher Knittel speaks with WBUR reporter Miriam Wasser about the benefits and risks associated with moving power lines underground. " We don't have to necessarily move to a system where everything is underground," says Knittel.  "What we really need to do is do a more targeted approach, which is identify the most critical lines in the network and do the cost-benefit test on undergrounding those."

Prof. Christopher Knittel speaks with New York Times reporter Claire Brown about the development of AI data centers and the potential of increased utility costs. “If it’s just a few industrial customers with behind-the-meter power plants, it doesn’t really matter,” says Knittel. [As data centers grow and expand] “these things are going to matter so much. We can get it right, but sadly, too, if we don’t do it right, we can get it really wrong.” 

Prof. Jacopo Buongiorno speaks with NBC News about the U.S. government airlifting parts of a nuclear reactor across three states and the future of nuclear power in America. “[It is] very positive. There is finally a sense of urgency and a push to increase our reliance on nuclear,” says Buongiorno. “I think nuclear has a lot of attractive features as an energy source. As I said earlier, it’s clean, it’s compact, it’s reliable.” 

Fast Company reporter Adele Peters spotlights Electrified Thermal Solutions, an MIT startup that has developed a new “thermal battery” that could be used to help power factories manufacturing energy-intensive materials like steel and cement. “The battery uses power from the grid to heat its custom bricks when electricity is cheap,” explains Peters. “When a factory needs hot air later, it’s provided by the superheated bricks.” 

Brian Bergstein at The Boston Globe speaks with Bob Mumgaard SM '15, PhD '15, CEO of MIT spinout Commonwealth Fusion Systems, about the company’s efforts to advance fusion technologies.  “When the federal government said in 2012 that it would cut funding for the experimental fusion reactor on campus, the MIT researchers took that as an opportunity to develop new fusion techniques — which eventually formed the basis of CFS’s plans,” writes Bergstein. 

In a roundup of the biggest tech breakthroughs of 2025, Forbes reporter Alex Knapp spotlights how MIT engineers developed magnetic transistors, a “discovery [that] could enable faster and more energy-efficient semiconductors.”

Researchers at MIT have developed a new physical model that can help “improve predictions of proton mobility across a wide range of metal oxides,” reports Ameya Paleja for Interesting Engineering. “This can help develop new materials and technologies powered by protons as charge carriers, rather than relying on lithium, which is widely used now,” explains Paleja. 

A study by MIT researchers examining the carbon emissions of self-driving cars found that “the power required to run one billion driverless vehicles driving for one hour per day could consume as much energy as all existing data centers in the world,” reports Claire Brown for The New York Times. Graduate student Soumya Sudhakar explains that another big unknown is how autonomous vehicles could change the way people travel, adding to the uncertainty over the overall long-term emissions outlook for self-driving cars. 

Writing for Physics Today, Prof. Yang Shao-Horn, Research Scientist Sokseiha Muy and their colleagues explain the limitations and concerns surrounding lithium-ion battery technology while highlighting the potential of solid-state batteries as an alternative. “Although solid electrolytes can significantly boost a battery’s energy density by minimizing the battery’s volume, the greatest gains come from replacing conventional graphite anodes with higher-capacity, low-electric-potential alternatives,” they write. 

Graduate student Chung-Tao (Josh) Chou speaks with Tech Briefs reporter Andrew Corselli about his work developing a magnetic transistor that could lead to more energy-efficient circuits. “People have known about magnets for thousands of years, but there are very limited ways to incorporate magnetism into electronics,” says Chou. “We have shown a new way to efficiently utilize magnetism that opens up a lot of possibilities for future applications and research.”

Researchers at MIT have developed a new method that can predict how plasma will behave in a tokamak reactor given a set of initial conditions, reports Gayoung Lee for Gizmodo. The findings “may have lowered one of the major barriers to achieving large-scale nuclear fusion,” explains Lee. 

Researchers at MIT have developed electron-conducting carbon concrete, a new kind of cement “that can store and release electricity like batteries,” reports Matthew Burgos for Design Boom. “MIT’s concrete battery shows a future where the material can be embedded into roads or parking areas to charge electric vehicles directly, or for off-grid homes that do not need external power,” Burgos explains.

Noman Bashir, a fellow with MIT’s Climate and Sustainability Consortium, speaks with Smithsonian Magazine reporter Amber X. Chen about the impact of AI data centers on the country’s electric grid and infrastructure. Bashir notes “that the industry’s environmental impacts can also be seen farther up the supply chain,” writes Chen. “The GPUs that power A.I. data centers are made with rare earth elements, the extraction of which Bashir notes is resource intensive and can cause environmental degradation.” 

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.”
