The Massachusetts Bay Transportation Authority moves hundreds of thousands of people across Greater Boston each day—thanks to a vast system of buses, trains, and ferries that depends on coordination among thousands of employees. In this storied transit system, history runs deep: The Green Line still passes through the country’s oldest subway tunnels, built beneath the…
Several years ago, Suzanne Berger was visiting a manufacturing facility in Ohio, talking to workers on the shop floor, when a machinist offered a thought that could serve as her current credo. “Technology takes a step forward—workers take a step forward too,” the employee said. Berger, to explain, is an MIT political scientist who for…
Concrete already builds our world, and an MIT-invented variant known as electron-conducting carbon concrete (ec3, pronounced “e c cubed”) holds out the possibility of helping power it, too. Now that vision is one step closer. Made by combining cement, water, ultra-fine carbon black, and electrolytes, ec3 creates a conductive “nanonetwork” that could enable walls, sidewalks,…
Earthquakes are driven by energy stored up in rocks over millennia—energy that, once released, we perceive mainly in the form of the ground’s shaking. But a quake also generates a flash of heat and fractures and damages underground rocks. And exactly how much energy goes into each of these three processes is exceedingly difficult to…
Lithium-ion batteries produce faint sounds as they charge, discharge, and degrade. But until now, nobody could interpret those sounds to detect when a battery might be about to lose power, fail, or burst into flames. Now, MIT engineers have found a way to do that, even with noisy data. The findings could provide the basis…
Right now, MIT alumni and friends are voicing their support for: America’s scientific and technological leadership Merit-based admissions and affordable education Advances that increase US health, security, and prosperity Our community is standing up for MIT and its mission to serve the nation and the world. And we need you to join us at this…
Nearly everyone has experienced it—after a night of poor sleep, your brain might seem foggy, and your mind drifts off when you should be paying attention. A new MIT study reveals what happens biologically as these momentary lapses occur: Your brain is performing essential maintenance that it usually takes care of while you sleep. During…
As MIT navigates a difficult and constantly changing higher education landscape, I believe our best response is not easy but simple: Keep doing our very best work. The presidential initiatives we’ve launched since fall 2024 are a vital part of our strategy to advance excellence within and across high-impact fields, from health care, climate, and…
Jaden Chizuruoke May ’29 worked with teammates Rihanna Arouna ’29 and Marian Akinsoji ’29 to design the chemically powered model car whose framework he is building in this scene from the Huang-Hobbs BioMaker Space, where students have a chance to work safely and independently with biological systems. The assignment to build the car—and the layered…
Ever since nuclear fusion was discovered in the 1930s, scientists have wondered if we could somehow replicate and harness the phenomenon behind starlight—the smashing together of hydrogen atoms to form helium and a stupendous amount of clean energy. Fusing hydrogen would yield 200 million times more energy than simply burning it. Unlike nuclear fission, which…
