What lies beneath

Why do people wear Rolex watches or drive Bentleys, when less expensive goods can perform better? Why does anyone fight the crowds at the Louvre to see the “Mona Lisa” for 30 seconds, when they could view it online for hours? Well, they may be engaging in “costly signaling,” in which people display their wealth […]

Anticipating others’ behavior on the road

Humans may be one of the biggest roadblocks keeping fully autonomous vehicles off city streets. If a robot is going to navigate a vehicle safely through downtown Boston, it must be able to predict what nearby drivers, cyclists, and pedestrians are going to do next. Behavior prediction is a tough problem, however, and current artificial […]

“Spring-loaded” system pops phosphorus into molecular rings

MIT chemists have devised a new chemical reaction that allows them to synthesize a phosphorus-containing ring, using a catalyst to add phosphorus to simple organic compounds called alkenes.

Ocean vital signs

Without the ocean, the climate crisis would be even worse than it is. Each year, the ocean absorbs billions of tons of carbon from the atmosphere, preventing warming that greenhouse gas would otherwise cause. Scientists estimate about 25 to 30 percent of all carbon released into the atmosphere by both human and natural sources is […]

Does this artificial intelligence think like a human?

In machine learning, understanding why a model makes certain decisions is often just as important as whether those decisions are correct. For instance, a machine-learning model might correctly predict that a skin lesion is cancerous, but it could have done so using an unrelated blip on a clinical photo. While tools exist to help experts […]

MIT’s Infinite Corridor — which is one-sixth of a mile long — mixes thousands of people together daily. Aerial walkways connect campus […]

A simple diagnostic tool for gastrointestinal disorders

As food moves through the digestive tract, contracting muscles along the tract keep things flowing smoothly. Loss of this motility can lead to acid reflux, failure of food to move out of the stomach, or constipation. Dysmotility disorders are usually diagnosed with a catheter containing pressure transducers, which can sense contractions of the GI tract. […]

Ride-hailing without the traffic snarls?

In theory, competition among ride-hailing companies should be a good thing, providing more options for consumers. In practice, having too many ride-hailing vehicles adds to urban congestion. How can cities balance these factors? A new study co-authored by MIT researchers, in collaboration with the Institute for Informatics and Telematics of the National Research Council of […]

Making quantum circuits more robust

Quantum computing continues to advance at a rapid pace, but one challenge that holds the field back is mitigating the noise that plagues quantum machines.
