David Li wins 2022 Marshall Scholarship
David Li, from Woodbury, Minnesota, has been selected as a Marshall Scholar and will commence graduate studies in the UK next fall. Funded by the British government, the Marshall Scholarship provides exceptional American students with the opportunity to pursue two years of advanced study in any field at any university in the U.K. Li, along with MIT’s other endorsed Marshall candidates, was mentored by the distinguished fellowships team in Career Advising and Professional Development, and the Presidential Committee on...

MIT joins the Black Economic Council of...
This fall, MIT joined the Black Economic Council of Massachusetts (BECMA), a Boston-based statewide organization that works to advance the economic well-being of Black businesses, organizations, and people in the Commonwealth. The Office of the Vice President for Finance (VPF) and the Office of Government and Community Relations (OGCR) jointly pursued membership in BECMA as part of an effort to increase MIT’s purchasing and contracting with minority-owned businesses, as highlighted in President Reif’s July 1, 2020 letter to the community...

“Newer, nimbler, faster:” Venus probe will search...
With multiple rovers landed and a mission set to return samples to Earth, Mars has dominated the search for life in the solar system for decades. But Venus has some fresh attention coming its way. In a new report published today, a team led by MIT researchers lays out the scientific plan and rationale for a suite of scrappy, privately-funded missions set to hunt for signs of life among the ultra-acidic atmosphere of the second planet from the sun....

A step toward “living biotherapeutics”
The human gut is home to thousands of species of bacteria, and some of those bacteria have the potential to treat a variety of gastrointestinal diseases. Some species may help to combat colon cancer, while others could help treat or prevent infections such as C. difficile. One of the obstacles to developing these “living biotherapeutics” is that many of the species that could be beneficial are harmed by oxygen, making it difficult to manufacture, store, and deliver them. MIT...

Research finds potential mechanism linking autism, intestinal...
Though many people with autism spectrum disorders also experience unusual gastrointestinal inflammation, scientists have not established how those conditions might be linked. Now MIT and Harvard Medical School researchers, working with mouse models, may have found the connection: When a mother experiences an infection during pregnancy and her immune system produces elevated levels of the molecule Interleukin-17a (IL-17a), this can not only alter brain development in her fetus, but also alter her microbiome such that after birth the newborn’s...

Graduate students honored with national math prize
Travis Dillon, a graduate student in mathematics at MIT, has been awarded the 2022 AMS-MAA-SIAM Frank and Brennie Morgan Prize for Outstanding Research in Mathematics by an Undergraduate Student, and fellow math doctoral student Alex Cohen has received an honorable mention. Dillon earned this year’s honor for his significant work in number theory, combinatorics, discrete geometry, and symbolic dynamics as an undergraduate at Lawrence University, where he studied mathematics and music theory. Dillon has completed seven papers, six of...

Machine-learning system flags remedies that might do...
Sepsis claims the lives of nearly 270,000 people in the U.S. each year. The unpredictable medical condition can progress rapidly, leading to a swift drop in blood pressure, tissue damage, multiple organ failure, and death. Prompt interventions by medical professionals save lives, but some sepsis treatments can also contribute to a patient’s deterioration, so choosing the optimal therapy can be a difficult task. For instance, in the early hours of severe sepsis, administering too much fluid intravenously can increase...

A tool to speed development of new...
In the ongoing race to develop ever-better materials and configurations for solar cells, there are many variables that can be adjusted to try to improve performance, including material type, thickness, and geometric arrangement. Developing new solar cells has generally been a tedious process of making small changes to one of these parameters at a time. While computational simulators have made it possible to evaluate such changes without having to actually build each new variation for testing, the process remains...

EECS graduate women’s research summit increases research...
The MIT Department of Electrical Engineering and Computer Science (EECS) group Graduate Women in Course 6 (GW6) held its third annual research summit on Nov. 5, with attendees convening in person along with a simultaneous webcast. The summit featured research lightning talks from graduate women and other underrepresented genders across EECS, as well as a keynote from Institute Professor Barbara Liskov and a panel of five prominent women in industry and academia. (Registration was open to all students and...

Tiny machine learning design alleviates a bottleneck...
Machine learning provides powerful tools to researchers to identify and predict patterns and behaviors, as well as learn, optimize, and perform tasks. This ranges from applications like vision systems on autonomous vehicles or social robots to smart thermostats to wearable and mobile devices like smartwatches and apps that can monitor health changes. While these algorithms and their architectures are becoming more powerful and efficient, they typically require tremendous amounts of memory, computation, and data to train and make inferences....

With “Hello!” as its theme, 2.009 returns...
On Monday night, Kresge Auditorium was lit up in the colors of the rainbow as a vibrant welcome for the final presentations of 2.009, MIT’s popular Product Engineering Processes course. After going virtual in 2020, the annual event was back in exuberant, pom-pom-waving form, with Covid-19 precautions in place to help ensure a safe and spectacular in-person show. To attend the night’s festivities, everyone 12 years and older was required to be vaccinated, and all guests were required to...

Meet the Oystamaran
When Michelle Kornberg was about to graduate from MIT, she wanted to use her knowledge of mechanical and ocean engineering to make the world a better place. Luckily, she found the perfect senior capstone class project: supporting sustainable seafood by helping aquaculture farmers grow oysters. “It’s our responsibility to use our skills and opportunities to work on problems that really matter,” says Kornberg, who now works for an aquaculture company called Innovasea. “Food sustainability is incredibly important from an...

Machines that see the world more like...
Computer vision systems sometimes make inferences about a scene that fly in the face of common sense. For example, if a robot were processing a scene of a dinner table, it might completely ignore a bowl that is visible to any human observer, estimate that a plate is floating above the table, or misperceive a fork to be penetrating a bowl rather than leaning against it. Move that computer vision system to a self-driving car and the stakes become...

Study reveals a protein’s key contribution to...
The versatility of the nervous system comes from not only the diversity of ways in which neurons communicate in circuits, but also their “plasticity,” or ability to change those connections when new information has to be remembered, when their circuit partners change, or other conditions emerge. A new study by neuroscientists at The Picower Institute for Learning and Memory of MIT shows how just one protein situated on the front lines of neural connections, or synapses, can profoundly change...
