Engineers develop surgical “duct tape” as an...

February 2, 2022

A staple on any engineer’s workbench, duct tape is a quick and dependable fix for cracks and tears in many structural materials. MIT engineers have now developed a kind of surgical duct tape — a strong, flexible, and biocompatible sticky patch that can be easily and quickly applied to biological tissues and organs to help seal tears and wounds. Like duct tape, the new patch is sticky on one side and smooth on the other. In its current formulation,...

Reducing methane emissions at landfills

February 2, 2022

The second-largest driver of global warming is methane, a greenhouse gas 28 times more potent than carbon dioxide. Landfills are a major source of methane, which is created when organic material decomposes underground. Now a startup that began at MIT is aiming to significantly reduce methane emissions from landfills with a system that requires no extra land, roads, or electric lines to work. The company, Loci Controls, has developed a solar-powered system that optimizes the collection of methane from...

The downside of machine learning in health...

February 1, 2022

While working toward her dissertation in computer science at MIT, Marzyeh Ghassemi wrote several papers on how machine-learning techniques from artificial intelligence could be applied to clinical data in order to predict patient outcomes. “It wasn’t until the end of my PhD work that one of my committee members asked: ‘Did you ever check to see how well your model worked across different groups of people?’” That question was eye-opening for Ghassemi, who had previously assessed the performance of...

2021-22 Takeda Fellows: Leaning on AI to...

February 1, 2022

In fall 2020, MIT’s School of Engineering and Takeda Pharmaceuticals Company Limited launched the MIT-Takeda Program, a collaboration to support members of the MIT community working at the intersection of artificial intelligence and human health. Housed at the Abdul Latif Jameel Clinic for Machine Learning in Health, the collaboration aims to use artificial intelligence to both benefit human health and aid in drug development. Combining technology with cutting-edge health research, the program’s participants hope to improve health outcomes across...

Antibodies, small proteins produced by the immune system, can attach to specific parts of a virus to neutralize it. As scientists continue to battle SARS-CoV-2, the virus that causes Covid-19, one possible weapon is a synthetic antibody that binds with the virus’ spike proteins to prevent the virus from entering a human cell. To develop a successful synthetic antibody, researchers must understand exactly how that attachment will happen. Proteins, with lumpy 3D structures containing many folds, can stick together...

How Omicron escapes from antibodies

February 1, 2022

A new study from MIT suggests that the dozens of mutations in the spike protein of the Omicron variant help it to evade all four of the classes of antibodies that can target the SARS-CoV-2 virus that causes Covid-19. This includes antibodies generated by vaccinated or previously infected people, as well as most of the monoclonal antibody treatments that have been developed, says Ram Sasisekharan, the Alfred H. Caspary Professor of Biological Engineering and Health Sciences and Technology (HST)...

Preparing global online learners for the clean...

January 31, 2022

After a career devoted to making the electric power system more efficient and resilient, Marija Ilic came to MIT in 2018 eager not just to extend her research in new directions, but to prepare a new generation for the challenges of the clean-energy transition. To that end, Ilic, a senior research scientist in MIT’s Laboratory for Information and Decisions Systems (LIDS) and a senior staff member at Lincoln Laboratory in the Energy Systems Group, designed an edX course that...

Professors Elchanan Mossel and Rosalind Picard named 2021...

January 28, 2022

The Association for Computing Machinery (ACM) has named MIT professors Elchanan Mossel and Rosalind Picard as fellows for outstanding accomplishments in computing and information technology. The ACM Fellows program recognizes wide-ranging and fundamental contributions in areas including algorithms, computer science education, cryptography, data security and privacy, medical informatics, and mobile and networked systems, among many other areas. The accomplishments of the 2021 ACM Fellows underpin important innovations that shape the technologies we use every day. Elchanan Mossel Mossel is a professor...

3 Questions: Jinhua Zhao on a “third...

January 28, 2022

During the Covid-19 pandemic, many office workers have developed flexible working arrangements, to avoid too much time spent in crowded offices. But an MIT-supported survey project reveals a twist on this now-familiar scenario: Many workers with location flexibility are not necessarily working from home. Instead, they are taking their work to a “third place,” including cafés, libraries, and co-working spaces. About one-third of nonoffice work hours are spent in such places, the data show, even if those locations put...

Tiny materials lead to a big advance...

January 27, 2022

Like the transistors in a classical computer, superconducting qubits are the building blocks of a quantum computer. While engineers have been able to shrink transistors to nanometer scales, however, superconducting qubits are still measured in millimeters. This is one reason a practical quantum computing device couldn’t be miniaturized to the size of a smartphone, for instance. MIT researchers have now used ultrathin materials to build superconducting qubits that are at least one-hundredth the size of conventional designs and suffer...

Demystifying machine-learning systems

January 27, 2022

Neural networks are sometimes called black boxes because, despite the fact that they can outperform humans on certain tasks, even the researchers who design them often don’t understand how or why they work so well. But if a neural network is used outside the lab, perhaps to classify medical images that could help diagnose heart conditions, knowing how the model works helps researchers predict how it will behave in practice. MIT researchers have now developed a method that sheds...

Immersive video game explores the history of...

January 26, 2022

A new video game, “A Lab of One’s Own,” creates an immersive environment in which players discover archival materials that tell the stories of women from MIT’s history. Created by multimedia artists Mariana Roa Oliva and Maya Bjornson with collections from MIT Libraries’ Women@MIT archival initiative, the project aims to create a multi-sensory, choose-your-own-adventure-style experience that challenges the idea that the past is behind us. “Our goal was to bring these materials into conversation through an engaging virtual space,”...

Vibrating atoms make robust qubits, physicists find

January 26, 2022

MIT physicists have discovered a new quantum bit, or “qubit,” in the form of vibrating pairs of atoms known as fermions. They found that when pairs of fermions are chilled and trapped in an optical lattice, the particles can exist simultaneously in two states — a weird quantum phenomenon known as superposition. In this case, the atoms held a superposition of two vibrational states, in which the pair wobbled against each other while also swinging in sync, at the...

Cynthia Breazeal named dean for digital learning...

January 26, 2022

In a letter to the MIT community today, Vice President for Open Learning Sanjay Sarma announced the appointment of Professor Cynthia Breazeal as dean for digital learning, effective Feb. 1. As dean, she will supervise numerous business units and research initiatives centered on developing and deploying digital technologies for learning. These include MIT xPRO, Bootcamps, Horizon, the Center for Advanced Virtuality, MIT Integrated Learning Initiative, RAISE, and other strategic initiatives. Breazeal has served as senior associate dean for open...

Building technological tools for nuclear disarmament

January 26, 2022

Mentorship has played a central role in the twists and turns of Associate Professor Areg Danagoulian’s life. As a boy, it led him first to mathematics, where a passionate teacher and mentorship from his parents instilled in him a love for the subject. He then followed in the footsteps of his physicist parents and became a physicist himself. During his career, mentorship has helped Danagoulian follow his research interests, from basic to applied nuclear physics and then to industry....
