Using AI, scientists find a drug that...

May 25, 2023

Using an artificial intelligence algorithm, researchers at MIT and McMaster University have identified a new antibiotic that can kill a type of bacteria that is responsible for many drug-resistant infections. If developed for use in patients, the drug could help to combat Acinetobacter baumannii, a species of bacteria that is often found in hospitals and can lead to pneumonia, meningitis, and other serious infections. The microbe is also a leading cause of infections in wounded soldiers in Iraq and...

MIT community members who work to eradicate...

May 24, 2023

On April 24, MIT celebrated outstanding students and employees at the annual Change-Maker Awards for their diligent work to eradicate sexual misconduct and support survivors. These architects of positive change exemplify one of MIT’s core values: striving to make our community a more humane and welcoming place where all can thrive. Hosted by MIT Violence Prevention and Response (VPR) and the Institute Discrimination and Harassment Response Office (IDHR), the awards are held each April to coincide with Sexual Assault...

Helping robots handle fluids

May 24, 2023

Imagine you’re enjoying a picnic by a riverbank on a windy day. A gust of wind accidentally catches your paper napkin and lands on the water’s surface, quickly drifting away from you. You grab a nearby stick and carefully agitate the water to retrieve it, creating a series of small waves. These waves eventually push the napkin back toward the shore, so you grab it. In this scenario, the water acts as a medium for transmitting forces, enabling you...

A better way to match 3D volumes

May 24, 2023

In computer graphics and computer-aided design (CAD), 3D objects are often represented by the contours of their outer surfaces. Computers store these shapes as “thin shells,” which model the contours of the skin of an animated character but not the flesh underneath. This modeling decision makes it efficient to store and manipulate 3D shapes, but it can lead to unexpected artifacts. An animated character’s hand, for example, might crumple when bending its fingers — a motion that resembles how...

Tiny diamond rotor could improve protein studies

May 24, 2023

Many of the biological materials that researchers are most interested in studying, including those associated with major diseases, don’t lend themselves to the conventional methods that researchers typically use to probe a material’s structure and chemistry. One technique, called magic-angle spinning nuclear magnetic resonance, or MAS-NMR, has proven highly successful as a way of determining the properties of complex molecules such as some proteins. But the resolution achievable with such systems depends on the spinning frequency of tiny rotors,...

Q&A: How studying Portuguese helps to look...

May 23, 2023

Theo St. Francis is an MIT senior majoring in aeronautics and astronautics. He is graduating this month with a concentration in Portuguese, and has visited Brazil with the MIT International Science and Technology Initiatives’ Global Teaching Labs. This year, St. Francis was the recipient of the Global Languages Margarita Ribas Groeger Distinguished Scholar award. In this Q&A, he describes how studying Portuguese fit into his undergraduate experience, and how it has broadened his world view. Q: What attracted you...

May 23, 2023

When we think of getting on the road in our cars, our first thoughts may not be that fellow drivers are particularly safe or careful — but human drivers are more reliable than one may expect. For each fatal car crash in the United States, motor vehicles log a whopping hundred million miles on the road. Human reliability also plays a role in how autonomous vehicles are integrated in the traffic system, especially around safety considerations. Human drivers continue...

Researchers use AI to identify similar materials...

May 23, 2023

A robot manipulating objects while, say, working in a kitchen, will benefit from understanding which items are composed of the same materials. With this knowledge, the robot would know to exert a similar amount of force whether it picks up a small pat of butter from a shadowy corner of the counter or an entire stick from inside the brightly lit fridge. Identifying objects in a scene that are composed of the same material, known as material selection, is...

MIT junior Anushree Chaudhuri named 2023 Udall...

May 22, 2023

MIT junior Anushree Chaudhuri has been selected as a 2023 Morris K. Udall and Stewart L. Udall Foundation Scholar. She is only the second MIT student to win this award and the first winner since 2008. The Udall Scholarship honors students who have demonstrated a commitment to the environment, Native American health care, or tribal public policy. Chaudhuri is one of 55 Udall Scholars selected nationally out of 384 nominated applicants. Chaudhuri, who hails from San Diego, studies urban...

Daniel Anderson receives 2023 Wilhelm Exner Medal

May 22, 2023

Professor Daniel Anderson has won the 2023 Wilhelm Exner Medal, awarded by the Austrian Industry Association, for excellence in research and science since 1921. Anderson will receive the award during the Wilhelm Exner Medal Foundation’s Exner Lectures, May 22-23 in Vienna, Austria. “Professor Anderson has changed our world,” says Elazer R. Edelman, Edward J. Poitras Professor in Medical Engineering and Science, and the director of the MIT Institute for Medical Engineering and Science (IMES). “The devices, and indeed concepts,...

From molecular to whole-brain scale in a...

May 22, 2023

Because serotonin is one of the primary chemicals the brain uses to influence mood and behavior, it is also the most common target of psychiatric drugs. To improve those drugs and to invent better ones, scientists need to know much more about how the molecule affects brain cells and circuits both in health and amid disease. In a new study, researchers at The Picower Institute for Learning and Memory at MIT working in a simple animal model present a...
