Volpe redevelopment project launches next phase

February 4, 2021

MIT’s proposed redevelopment of the 14-acre Volpe parcel in Kendall Square is ready to start a new chapter in its review and approval process. With the Institute’s design and construction of the new John A. Volpe National Transportation Systems Center on four acres of the site underway, the Volpe team is now focusing on the remaining 10 acres of the parcel. This planned two-step process was anticipated in the Volpe zoning agreement with the city as the federal government...

Machine-learning model helps determine protein structures

February 4, 2021

Cryo-electron microscopy (cryo-EM) allows scientists to produce high-resolution, three-dimensional images of tiny molecules such as proteins. This technique works best for imaging proteins that exist in only one conformation, but MIT researchers have now developed a machine-learning algorithm that helps them identify multiple possible structures that a protein can take. Unlike AI techniques that aim to predict protein structure from sequence data alone, protein structure can also be experimentally determined using cryo-EM, which produces hundreds of thousands, or even...

Bryan Stevenson to deliver MIT’s 2021 Commencement...

February 4, 2021

Bryan Stevenson, a civil rights lawyer acclaimed for his work confronting bias against the poor and people of color in the U.S. justice system, will deliver the address at MIT’s 2021 Commencement exercises on Friday, June 4. Stevenson is the founder and executive director of the Equal Justice Initiative, a human rights organization in Montgomery, Alabama, which has won legal challenges eliminating excessive and unfair sentencing, exonerating innocent death row prisoners, confronting abuse of the incarcerated and the mentally...

Building equity into vaccine distribution

February 4, 2021

Two of the studies described in this article have been published on a preprint server but have not yet been peer-reviewed by experts in the field. As the U.S. speeds up distribution of Covid-19 vaccines, the question of equity keeps surfacing. Who gets priority? If the pandemic is hitting certain communities harder, can they be adequately supplied with vaccine doses? What’s the best way to balance the needs of different groups within society? MIT economist Parag Pathak’s work emphasizes...

Scientists as engaged citizens

February 3, 2021

The classroom in fall 2020 looked very different than it did when WGS.160/STS.021 (Science Activism: Gender, Race, and Power) ran for the first time in 2019. Zoom and virtual breakout rooms had replaced circles of chairs, but the shifts made the class no less immersive and urgent for its students. In fact, the pandemic context made the core questions of this new survey class all the more vivid: What roles have U.S. scientists and technologists played as activists in...

Epigenomic map reveals circuitry of 30,000 human...

February 3, 2021

Twenty years ago this month, the first draft of the human genome was publicly released. One of the major surprises that came from that project was the revelation that only 1.5 percent of the human genome consists of protein-coding genes. Over the past two decades, it has become apparent that those noncoding stretches of DNA, originally thought to be “junk DNA,” play critical roles in development and gene regulation. In a new study published today, a team of researchers...

An art lover dreams of space

February 3, 2021

It started with a movie. Supernovas filled the screen and exploded with galactic color. The voice of Neil DeGrasse Tyson narrated the beginning of the universe. At only 14 years old, Alana Sanchez was hooked. Prior to high school, Sanchez was primarily interested in visual arts and movies. She taught herself animation and aspired to work in the creative realm. However, her dreams quickly transformed after watching the popular science documentary, “Cosmos: A Spacetime Odyssey.” Today, Sanchez is an...

An origami-inspired medical patch for sealing internal...

February 2, 2021

Many surgeries today are performed via minimally invasive procedures, in which a small incision is made and miniature cameras and surgical tools are threaded through the body to remove tumors and repair damaged tissues and organs. The process results in less pain and shorter recovery times compared to open surgery. While many procedures can be performed in this way, surgeons can face challenges at an important step in the process: the sealing of internal wounds and tears. Taking inspiration...

Faster tracking of treatment responses

February 2, 2021

In the fight against severe diseases like cancer, patients often endure a discomforting, weekslong gap between when treatment begins and when doctors can tell if it’s working. The problem often stems from an inability to track the disease’s progression in anything close to real time. Now Glympse Bio, a startup spun out of the lab of Sangeeta Bhatia, the John J. and Dorothy Wilson Professor of Electrical Engineering and Computer Science at MIT and director of the Marble Center...

Physicists create tunable superconductivity in twisted graphene...

February 1, 2021

When two sheets of graphene are stacked atop each other at just the right angle, the layered structure morphs into an unconventional superconductor, allowing electric currents to pass through without resistance or wasted energy. This “magic-angle” transformation in bilayer graphene was observed for the first time in 2018 in the group of Pablo Jarillo-Herrero, the Cecil and Ida Green Professor of Physics at MIT. Since then, scientists have searched for other materials that can be similarly twisted into superconductivity,...

J-PAL North America calls for proposals from...

February 1, 2021

J-PAL North America, a research center in the MIT Department of Economics, has announced the latest round of its State and Local Innovation Initiative’s Innovation Competition, which supports state and local governments in using rigorous evaluation to answer critical questions about what works in reducing poverty. For the past year, state and local governments across the United States have faced tremendous challenges, including a pandemic that has resulted in incalculable losses for millions of Americans, unprecedented natural disasters brought on...

Our gut-brain connection

January 29, 2021

In many ways, our brain and our digestive tract are deeply connected. Feeling nervous may lead to physical pain in the stomach, while hunger signals from the gut make us feel irritable. Recent studies have even suggested that the bacteria living in our gut can influence some neurological diseases. Modeling these complex interactions in animals such as mice is difficult to do, because their physiology is very different from humans’. To help researchers better understand the gut-brain axis, MIT...

Foreign policy advice: Don’t look back

January 29, 2021

President Joe Biden’s administration represents a fresh start for the U.S. in foreign affairs. But as experts observed at an online MIT panel on Wednesday, the U.S. cannot just reset foreign policy to the last time Biden worked in the White House, as vice-president in the Obama administration. Too many things have changed, too dramatically, in the last four years. “You can’t rewind the clock at a time when, frankly, great power rivalry is higher than it ever was,”...

How will Covid-19 ultimately impact climate change?

January 29, 2021

Business closures. Travel restrictions. Working and learning from home. These and other dramatic responses to Covid-19 have caused sharp reductions in economic activity — and associated fossil fuel consumption — around the world. As a result, many nations are reporting significant reductions in greenhouse gas emissions for the year 2020, edging them a bit closer to meeting the initial emissions targets to which they committed under the Paris Agreement on climate change. While the pandemic may have accelerated progress...

MIT developing framework for Covid-19 vaccinations on...

January 29, 2021

The Commonwealth of Massachusetts has approved MIT’s request to serve as an employer-based distributor of the Covid-19 vaccine. The designation means that as sufficient doses of the vaccine become available over the coming months, the Institute will be in a position to vaccinate some 50,000 MIT students, employees, affiliates, and their dependents — regardless of whether MIT Medical is their primary care provider. MIT brings to this effort its long track record running one of the largest flu vaccination...
