Q&A: Bettina Stoetzer on envisioning a livable...

March 22, 2022

In an ongoing series, MIT faculty, students, and alumni in the humanistic fields share perspectives that are significant for solving the economic, political, ethical, and cultural dimensions of climate change, as well as mitigating its myriad social and ecological impacts. Bettina Stoetzer is the Class of 1948 Career Development Associate Professor of Anthropology at MIT; her research combines perspectives on ecology and environmental change with an analysis of migration, race, and social justice. In this conversation with SHASS Communications,...

Lawrence Udeigwe uses elegant math to understand...

March 22, 2022

It’s a tale familiar to many first-generation students: Neither of Lawrence Udeigwe’s parents had more than a sixth-grade education, and yet they were willing to sacrifice everything to educate their children. “My dad,” Udeigwe says, “would tell us, ‘I’m ready to sell everything for you guys to go to school.’” Udeigwe recounts that in Nigeria at the time, achieving the sort of success and stability his parents hoped for meant studying something practical and working for the government. So,...

A simple diagnostic tool for gastrointestinal disorders

March 22, 2022

As food moves through the digestive tract, contracting muscles along the tract keep things flowing smoothly. Loss of this motility can lead to acid reflux, failure of food to move out of the stomach, or constipation. Dysmotility disorders are usually diagnosed with a catheter containing pressure transducers, which can sense contractions of the GI tract. MIT researchers have now designed a new device that could offer a cheaper and easier-to-manufacture alternative to existing diagnostics for GI dysmotility, inspired by...

Yukiko Yamashita, unraveler of stem cells’ secrets

March 22, 2022

When cells divide, they usually generate two identical daughter cells. However, there are some important exceptions to this rule: When stem cells divide, they often produce one differentiated cell along with another stem cell, to maintain the pool of stem cells. Yukiko Yamashita has spent much of her career exploring how these “asymmetrical” cell divisions occur. These processes are critically important not only for cells to develop into different types of tissue, but also for germline cells such as...

Ride-hailing without the traffic snarls?

March 22, 2022

In theory, competition among ride-hailing companies should be a good thing, providing more options for consumers. In practice, having too many ride-hailing vehicles adds to urban congestion. How can cities balance these factors? A new study co-authored by MIT researchers, in collaboration with the Institute for Informatics and Telematics of the National Research Council of Italy, provides a model that shows the extent to which ride-sharing competition clogs the streets — allowing analysts and policymakers to estimate how many...

3 Questions: Jackson Lu on the “bamboo...

March 21, 2022

In the U.S., ethnic East Asians are often depicted as a “model minority” and assumed to be thriving in educational and professional terms. But reality is more complex. A new study co-authored by Jackson Lu, the Mitsui Career Development Professor in the MIT Sloan School of Management, finds that students of East Asian descent often struggle in U.S. business schools and law schools, seemingly due to a culturally influenced lack of vocal assertiveness in these classroom settings — where...

Last-minute pivot leads to record-setting Microsystems Annual...

March 18, 2022

Graduate student co-chairs Jatin Patil and Kruthika Kikkeri had big plans for the 18th annual Microsystems Annual Research Conference (MARC) in January 2022: After last year’s all-virtual event, students, faculty, staff, and industry partners would again be able to gather in person to chart the future of microsystems and nanotechnology. Then the pandemic took another turn. As the Omicron variant surged and with only three weeks to pivot, Kikkeri and Patil led the 16-person MARC student committee to redirect...

Q&A: Latifah Hamzah ’12 on creating sustainable...

March 18, 2022

Latifah Hamzah ’12 graduated from MIT with a BS in mechanical engineering and minors in energy studies and music. During their time at MIT, Latifah participated in various student organizations, including the MIT Symphony Orchestra, Alpha Phi Omega, and the MIT Design/Build/Fly team. They also participated in the MIT Energy Initiative’s Undergraduate Research Opportunities Program (UROP) in the lab of former professor of mechanical engineering Alexander Mitsos, examining solar-powered thermal and electrical co-generation systems. After graduating from MIT, Hamzah...

Setting carbon management in stone

March 17, 2022

Keeping global temperatures within limits deemed safe by the Intergovernmental Panel on Climate Change means doing more than slashing carbon emissions. It means reversing them. “If we want to be anywhere near those limits , then we have to be carbon neutral by 2050, and then carbon negative after that,” says Matěj Peč, a geoscientist and the Victor P. Starr Career Development Assistant Professor in the Department of Earth, Atmospheric, and Planetary Sciences (EAPS). Going...

Investing in a stronger MIT

March 17, 2022

MIT plans to make significant investments in the next fiscal year to support the Institute community, strengthen its research enterprise, and enhance its digital and physical infrastructure. The Institute announced in October that its pooled investments recorded a return of 55.5 percent — the strongest annual performance in more than 20 years — bringing the endowment to $27.4 billion. These exceptional results provided a unique opportunity for MIT to accelerate distribution from its endowment to tackle an array of...

3 Questions: How the MIT mini cheetah...

March 17, 2022

It’s been roughly 23 years since one of the first robotic animals trotted on the scene, defying classical notions of our cuddly four-legged friends. Since then, a barrage of the walking, dancing, and door-opening machines have commanded their presence, a sleek mixture of batteries, sensors, metal, and motors. Missing from the list of cardio activities was one both loved and loathed by humans (depending on whom you ask), and which proved slightly trickier for the bots: learning to run. ...

Handheld surgical robot can help stem fatal...

March 17, 2022

After a traumatic accident, there is a small window of time when medical professionals can apply lifesaving treatment to victims with severe internal bleeding. Delivering this type of care is complex, and key interventions require inserting a needle and catheter into a central blood vessel, through which fluids, medications, or other aids can be given. First responders, such as ambulance emergency medical technicians, are not trained to perform this procedure, so treatment can only be given after the victim...

Pandemic mood: Much worse than a bad...

March 17, 2022

The Covid-19 pandemic has been depressing, demoralizing, and stressful for people around the world. But is there any way to measure exactly how bad it has made everyone feel? A new study led by MIT researchers attempts just that, through a massive examination of hundreds of millions social media posts in about 100 countries. The research, which analyzes the language terms used in social media, finds a pronounced drop in positive public sentiment after the pandemic set in during...

Q&A: Climate Grand Challenges finalists on accelerating...

March 17, 2022

This is the second article in a four-part interview series highlighting the work of the 27 MIT Climate Grand Challenges finalists, which received a total of $2.7 million in startup funding to advance their projects. In April, the Institute will name a subset of the finalists as multiyear flagship projects. Last month, the Intergovernmental Panel on Climate Change (IPCC), an expert body of the United Nations representing 195 governments, released its latest scientific report on the growing threats posed...

A possible new Covid-19 vaccine could be...

March 16, 2022

While many people in wealthier countries have been vaccinated against Covid-19, there is still a need for vaccination in much of the world. A new vaccine developed at MIT and Beth Israel Deaconess Medical Center may aid in those efforts, offering an inexpensive, easy-to-store, and effective alternative to RNA vaccines. In a new paper, the researchers report that the vaccine, which comprises fragments of the SARS-CoV-2 spike protein arrayed on a virus-like particle, elicited a strong immune response and...
