Investors awaken to the risks of climate...

February 4, 2022

Poppy Allonby, a senior financial executive and the former managing director of BlackRock, has been analyzing the link between climate change and investing for more than two decades. “For a lot of that, it was quite lonely,” Allonby said during her December address at the MIT Energy Initiative Fall Colloquium. “There weren’t that many other people looking at this field. And over the last three or four years, that’s completely changed.” Increasingly, Allonby said, investors are opening their eyes...

Is an armed conflict imminent?

February 4, 2022

In recent weeks it has seemed increasingly possible that Russia will invade Ukraine. But why is this threat unfolding now, and what is likely to occur? An online panel of experts held by MIT last Friday warned of significant reason for concern, while searching for factors that might prevent military action or limit its consequences. In general, the scholars on the panel viewed Russia as driving toward reestablishment of a sphere of control similar to that held by the...

February 3, 2022

Imagine a ball thrown in the air: It curves up, then down, tracing an arc to a point on the ground some distance away. The path of the ball can be described with a simple mathematical equation, and if you know the equation, you can figure out where the ball is going to land. Biological systems tend to be harder to forecast, but MIT professor of biology Jonathan Weissman, postdoc Xiaojie Qiu, and collaborators at the University of Pittsburgh...

An honor that empowers change

February 3, 2022

“I grew up thinking government was useless,” says Michelle Tang. Today, the aerospace engineering major is engaged in community organizing and plans a career in public service and policy. Central to Tang’s change of heart, and direction, was an immersive summer 2021 internship as a legislative assistant for Massachusetts State Representative Erika Uyterhoeven, working on a project to make local government more transparent to constituents. Tang says she learned how elected officials can “pull levers of power to get...

MIT experts test technical research for a...

February 3, 2022

In collaboration with a team at the Federal Reserve Bank of Boston, MIT experts have begun designing and testing technical research through which further examination of a Central Bank Digital Currency (CBDC) can be performed in the U.S. The effort, known as Project Hamilton, is in an exploratory phase, and the research is not intended as a pilot or for public deployment. Instead, the researchers have explored two different approaches that could be used to process transactions, and thus...

Probing how proteins pair up inside cells

February 3, 2022

Despite its minute size, a single cell contains billions of molecules that bustle around and bind to one another, carrying out vital functions. The human genome encodes about 20,000 proteins, most of which interact with partner proteins to mediate upwards of 400,000 distinct interactions. These partners don’t just latch onto one another haphazardly; they only bind to very specific companions that they must recognize inside the crowded cell. If they create the wrong pairings — or even the right...

3 Questions: Women’s rights and rising threats...

February 2, 2022

To Ada Petriczko, being born a woman can be a matter of life or death. Hailing from Poland, she reports on sexual violence and gender injustices around the globe. As a human rights journalist, her mission is to amplify the voices of women who have been systematically silenced by their communities and governments. Their stories have to be heard, she argues, in order to reshape our societies. This includes reporting on her home country, where democratic stability and women’s...

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...

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)...

Artificial intelligence system rapidly predicts how two...

February 1, 2022

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...

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...
