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.”
MIT researchers have developed a new model that illustrates the chemical mechanisms underlying lithium-ion batteries, reports Gayoung Lee for Gizmodo. The findings could “lead to faster, more efficient batteries for electric vehicles, portable electronics, and more.”
Leah Ellis, a former MIT postdoc and co-founder of MIT startup Sublime Systems, speaks with Nature reporter Jacqui Thornton about the creation of the company. “I felt that the word Sublime encapsulated the spirit of excellence, transcendence and purity that we intend to exemplify as we build a technology and a company that we hope will change the world — and the inherent properties of cement itself.”
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 developed a new self-assembling battery material that could help combat growing concerns about EV battery waste, reports Grace Snelling for Fast Company. The new method “makes it much easier to separate [battery] component parts, leaving them ready for recycling,” writes Snelling.
Inspired by a scene in Harry Potter, researchers at MIT have developed a new self-assembling battery material that could one day serve as an “easy-to-recycle alternative for manufacturing EV batteries,” reports Gayoung Lee for Gizmodo. Notably, the process doesn’t require the harsh chemical and thermal conditions that make EV battery recycling so difficult, offering promising opportunities for recycling the batteries at scale.”
WBUR reporter Rachell Sanchez-Smith spotlights two health tech devices being developed by Prof. Yoel Fink and Prof. Canan Dağdeviren, respectively, that aim to “give the wearers — and their doctors — a clearer picture of their overall health.” Fink has created “a thread capable of storing data, running artificial intelligence algorithms, sensing motion and sound, and communication through Bluetooth,” while Dağdeviren’s wearable ultrasound scanner can be used to make breast cancer screening “more comfortable and more accurate,” explains Sanchez-Smith.
Leah Ellis, a former MIT postdoc and co-founder of MIT startup Sublime Systems, speaks with Nature reporter Emma Ulker about the company’s mission to reduce carbon emissions from cement production, how her work with co-founder Prof. Yet-Ming Chiang helped inspire her entrepreneurial journey, and her philosophy as a science entrepreneur. “At Sublime, we are tackling a hard problem — pun intended — because the cement industry is one of the most difficult to approach, owing to its sheer scale,” explains Ellis. “The motivation for our work is that change in cement-making technology has a significant impact — it’s really only once in a millennium that you get to rethink such a foundational and monumental building material.”
Prof. Emeritus Donald Sadoway speaks with Forbes reporter Neil Winton about the development of solid-state batteries and the future of electric vehicles. “Yes, in 2035 the U.S. the automobile market will be roughly the same as today, but by then the massive demand for electricity from computers, AI and EVs will combine to demand more electricity than the grid can supply,” says Sadoway.
Interesting Engineering reporter Saoirse Kerrigan spotlights a number of MIT research projects from the past decade. MIT has “long been a hub of innovation and ingenuity across multiple industries and disciplines,” writes Kerrigan. “Every year, the school’s best and brightest debut projects that push the boundaries of science and technology. From vehicles and furniture to exciting new breakthroughs in electricity generation, the school’s projects have tackled an impressive variety of subjects.”
Researchers at MIT have created “a resin that turns into two different kinds of solids, depending on the type of light that shines on it,” a development that could “significantly speed up the 3D-printing process,” reports Andrew Corselli for Tech Briefs. Graduate student Nicholas Diaco explains that this new method “allows us in a single 3D print, to create structures that either dissolve or don't dissolve away. That lets us automate the most difficult and most expensive step of 3D printing, which is removing support materials after the printing is done.”
Researchers at MIT have developed an “AI-powered tool that scans scientific literature and over 1 million rock samples to identify materials that can partially replace cement in concrete,” reports Samanatha Hindman for Yahoo! News. The new system could “change how we build cities forever,” says Hindman. “The system sorts materials based on their physical and chemical properties, narrowing them down by how well they hold concrete together when mixed with water (hydraulic reactivity) and how they strengthen it over time (pozzolanicity).”
Prof. Yet-Ming Chiang, Shreya Dave '09, SM ’12, PhD '16, Bob Mumgaard SM '15, PhD '15 and Sloan alumna Emily Reichert have been named to the 2025 Boston Globe Tech Power Players list for their efforts in the energy sector, reports Hiawatha Bray for The Boston Globe. Chiang emphasizes the importance of federal funding in advancing scientific research. “My entire career has been supported by US taxpayers,” Chiang says. “The ability to give back and develop technologies and create jobs, that’s a big motivator for me.”
Felice Frankel, a research scientist in the MIT Department of Chemical Engineering and a science photographer, speaks with Science Friday host Flora Lichtman about science communicators can more effectively engage the public and make a better case for the importance of scientific research.
Prof. Yet-Ming Chiang and his colleagues have developed a sodium-air fuel cell that “packs three to four times more energy per pound than common lithium-ion batteries,” reports Aaron Pressman for The Boston Globe, which could serve as “a potentially groundbreaking clean power source for airplanes.” Pressman adds that: “Ultimately, a sodium-air fuel cell could power a regional jet carrying 50 to 100 passengers on flights as long as 300 miles.”
