Fourth Power is developing thermal batteries to efficiently store excess electricity at scale. The technology heats carbon bricks to white-hot temperatures: “You transfer heat at a higher rate and shrink the system. Then everything gets cheaper,” Asegun Henry says.
A new sensor can detect compounds in a person’s breath to quickly diagnose pneumonia and other lung conditions. Rather than sit for a chest X-ray or wait hours for a lab result, a patient may one day take a breath test and get a diagnosis within minutes.
Can AI help patients and their doctors manage heart failure? Researchers developed a deep-learning model to forecast a patient’s heart failure prognosis up to a year in advance.
On a typical photonic chip, light travels in wires, but a new system precisely broadcasts light off the chip into free space in a scalable way. This could lead to advanced displays, high-speed optical communications, and larger-scale quantum computers.
Song Han is working to shrink and speed up large AI models, cutting their energy use and lowering their cost. As a guest on President Kornbluth’s Curiosity Unbounded podcast, he discussed why AI is so energy-hungry and the benefits of lighter models.
In a world without MIT, radar wouldn’t have been available to help win World War II. We might not have email, CT scans, time-release drugs, photolithography, or GPS. And we’d lose over 30,000 companies, employing millions of people. Can you imagine?
Since its founding, MIT has been key to helping American science and innovation lead the world. Discoveries that begin here generate jobs and power the economy — and what we create today builds a better tomorrow for all of us.
