J-PAL North America announces six new evaluation...

April 28, 2023

J-PAL North America, a regional office of MIT’s Abdul Latif Jameel Poverty Action Lab (J-PAL), has announced six new partnerships with government agencies and leading nonprofits through the State and Local Evaluation Incubator and the Housing Stability Evaluation Incubator, launched in August 2022. These collaborators span the contiguous United States and represent a wide range of social policy areas. Over the next several months, organizations will work with J-PAL North America staff and affiliated researchers to design a randomized evaluation...

Study: Covid-19 has reduced diverse urban interactions

April 28, 2023

The Covid-19 pandemic has reduced how often urban residents intersect with people from different income brackets, according to a new study led by MIT researchers. Examining the movement of people in four U.S. cities before and after the onset of the pandemic, the study found a 15 to 30 percent decrease in the number of visits residents were making to areas that are socioeconomically different than their own. In turn, this has reduced people’s opportunities to interact with others...

Asegun Henry wins National Science Foundation’s Alan...

April 27, 2023

The National Science Foundation (NSF) today named Asegun Henry, an associate professor in MIT’s Department of Mechanical Engineering, as a 2023 recipient of its Alan T. Waterman Award. This award is the NSF’s highest honor for early-career researchers and provides funding for research in any science or engineering field. This is the second year NSF has chosen to honor three researchers with the award. Henry is the sixth faculty member from MIT to receive this honor in its 47-year history,...

How to untangle a worm ball: Mathematicians...

April 27, 2023

As anyone who has ever unwound a string of holiday lights or detangled a lock of snarled hair knows, undoing a knot of fibers takes a lot longer than tangling it up in the first place. This is not so for a wily species of West Coast worm. Found in marshes, ponds, and other shallow waters, California blackworms (Lumbriculus variegatus) twist and curl around each other by the thousands, forming tightly wound balls over several minutes. In the face...

MIT engineers “grow” atomically thin transistors on...

April 27, 2023

Emerging AI applications, like chatbots that generate natural human language, demand denser, more powerful computer chips. But semiconductor chips are traditionally made with bulk materials, which are boxy 3D structures, so stacking multiple layers of transistors to create denser integrations is very difficult. However, semiconductor transistors made from ultrathin 2D materials, each only about three atoms in thickness, could be stacked up to create more powerful chips. To this end, MIT researchers have now demonstrated a novel technology that...

Robert Armstrong: A lifetime at the forefront...

April 27, 2023

Robert C. Armstrong, the Chevron Professor of Chemical Engineering who has been the director of the MIT Energy Initiative (MITEI) since 2013 and part of MITEI’s leadership team since its inception in 2007, has announced that he will retire effective June 30. At that time he will have completed 50 years on the MIT faculty. Armstrong plans to continue to work at 10 percent capacity, focusing on research projects on which he serves as principal investigator and also advising...

Study offers a new view of when...

April 27, 2023

Allocating land for people to use is one of the most powerful tools a government can have. A newly published study by an MIT scholar now identifies the extent to which state land distribution can be a politically charged act. The research, focused on Kenya in recent decades, challenges some conventional wisdom while bringing new empirical data to the subject. To explain the “property rights gap” in some countries — in which people do not own the land they...

Ingestible “electroceutical” capsule stimulates hunger-regulating hormone

April 26, 2023

Hormones released by the stomach, such as ghrelin, play a key role in stimulating appetite. These hormones are produced by endocrine cells that are part of the enteric nervous system, which controls hunger, nausea, and feelings of fullness. MIT engineers have now shown that they can stimulate these endocrine cells to produce ghrelin, using an ingestible capsule that delivers an electrical current to the cells. This approach could prove useful for treating diseases that involve nausea or loss of...

Knight Science Journalism Program announces 2023-24 fellows

April 25, 2023

The internationally renowned Knight Science Journalism Program at MIT has announced the 10 elite science journalists who will make up its 2023-24 fellowship class. Selected from more than 100 applicants, the group comprises award-winning print, audio, and multimedia journalists hailing from seven countries and five continents. “We’re excited to welcome such an accomplished group of journalists to Cambridge,” says Knight Science Journalism Program Director Deborah Blum. “It’s a pleasure to see such a rich variety of reporting backgrounds and...

Hanna has more than 15 years of experience working across the public, private, and nonprofit sectors, with the purpose of creating a more equitable and sustainable world. She spent the last six years at MIT Solve, where she helped build the initiative into a global community. Solve uses open innovation...

A simple paper test could offer early...

April 25, 2023

MIT engineers have designed a new nanoparticle sensor that could enable early diagnosis of cancer with a simple urine test. The sensors, which can detect many different cancerous proteins, could also be used to distinguish the type of a tumor or how it is responding to treatment. The nanoparticles are designed so that when they encounter a tumor, they shed short sequences of DNA that are excreted in the urine. Analyzing these DNA “barcodes” can reveal distinguishing features of...

MIT graduate engineering, business, science programs ranked...

April 25, 2023

U.S. News and Word Report has again placed MIT’s graduate program in engineering at the top of its annual rankings. The Institute has held the No. 1 spot since 1990, when the magazine first ranked such programs. The MIT Sloan School of Management also placed highly. It occupies the No. 4 spot for the best graduate business programs, tied with Harvard University. Among individual engineering disciplines, MIT placed first in six areas: aerospace/aeronautical/astronautical engineering, chemical engineering, computer engineering, electrical/electronic/communications...

Researchers 3D print a miniature vacuum pump

April 25, 2023

Mass spectrometers are extremely precise chemical analyzers that have many applications, from evaluating the safety of drinking water to detecting toxins in a patient’s blood. But building an inexpensive, portable mass spectrometer that could be deployed in remote locations remains a challenge, partly due to the difficulty of miniaturizing the vacuum pump it needs to operate at a low cost. MIT researchers utilized additive manufacturing to take a major step toward solving this problem. They 3D printed a miniature...

Martin Wainwright named director of the Institute...

April 24, 2023

Martin Wainwright, the Cecil H. Green Professor in MIT’s departments of Electrical Engineering and Computer Science (EECS) and Mathematics, has been named the new director of the Institute for Data, Systems, and Society (IDSS), effective July 1. “Martin is a widely recognized leader in statistics and machine learning — both in research and in education. In taking on this leadership role in the college, Martin will work to build up the human and institutional behavior component of IDSS, while...

Learner in Afghanistan reaches beyond barriers to...

April 24, 2023

Tahmina S. was a junior studying computer engineering at a top university in Afghanistan when a new government policy banned women from pursuing education. In August 2021, the Taliban prohibited girls from attending school beyond the sixth grade. While women were initially allowed to continue to attend universities, by October 2021, an order from the Ministry of Higher Education declared that all women in Afghanistan were suspended from attending public and private centers of higher education. Determined to continue...
