Copper, a startup founded by Sam Calisch SM ’14, PhD ’19, has developed a battery-equipped kitchen range that can plug into a standard wall outlet. The induction range features a lithium iron phosphate battery that charges when energy is cheapest.

Focusing on the risk of nuclear escalation, Caitlin Talmadge studies militaries’ on-the-ground capabilities and how they are influenced by political circumstances. “It’s important for me to do scholarship that speaks to real-world problems,” she says.

A deep-learning model from Alex Shalek and colleagues “was up to 17 times more effective at finding relevant compounds than standard, brute-force drug screening that depends on randomly selecting compounds from a chemical library,” Nature reported.

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.
