A better nasal swab for Covid-19 testing

April 8, 2021

Over nearly seven years researching 3D printing systems in MIT’s Media Lab, Jifei Ou SM ’14, PhD ’19 began to suspect the work could lead to better products. He never could have imagined it would help address supply shortages caused by a global pandemic. Since March of last year, Ou’s company, OPT Industries, has been working with hospitals to deliver a new type of nasal swab for Covid-19 testing. The swabs make use of thin, hairlike structures Ou developed while at...

The MIT Press launches MIT Open Publishing...

April 6, 2021

The MIT Press has announced the launch of MIT Open Publishing Services, a scholar-focused, MIT-branded hosting and publishing services operation. MIT Open Publishing Services (MITops), working with its partner the Knowledge Futures Group, provides a portfolio of services to mission-aligned partners, including peer review support and editorial development; professional copy editing and design; marketing and publicity; and hosting on the PubPub open source platform. The MIT Press believes that the full potential of institutionally owned and managed infrastructure will be realized by pairing publishing technology...

How MIT OpenCourseWare became an educational resource...

April 6, 2021

“It is typical of our faculty to come up with something as bold and innovative as this,” said then-MIT president Charles Vest at a special gathering of community members and press in April 2001. “OpenCourseWare looks counterintuitive in a market-driven world. It goes against the grain of current material values. But it really is consistent with what I believe is the best about MIT … It expresses our belief in the way education can be advanced — by constantly...

Seeking the cellular mechanisms of disease, with...

April 6, 2021

Caroline Uhler’s research blends machine learning and statistics with biology to better understand gene regulation, health, and disease. Despite this lofty mission, Uhler remains dedicated to her original career passion: teaching. “The students at MIT are amazing,” says Uhler. “That’s what makes it so fun to work here.” Uhler recently received tenure in the Department of Electrical Engineering and Computer Science. She is also an associate member of the Broad Institute of MIT and Harvard, and a researcher at...

A safer way to deploy bacteria as...

April 5, 2021

In recent years, scientists have developed many strains of engineered bacteria that can be used as sensors to detect environmental contaminants such as heavy metals. If deployed in the natural environment, these sensors could help scientists track how pollutant levels change over time, over a wide geographic area. MIT engineers have now devised a way to make this kind of deployment safer, by encasing bacterial sensors in a tough hydrogel shell that prevents them from escaping into the environment...

What has the pandemic revealed about the...

April 5, 2021

With vaccinations for Covid-19 now underway across the nation, MIT SHASS Communications asked seven MIT scholars engaged in health and health care research to share their views on what the pandemic has revealed about the U.S. health care system — and what needs to change. Representing the fields of medicine, anthropology, political science, health economics, science writing, and medical humanities, these researchers articulate a range of opportunities for U.S. health care to become more equitable, more effective and coherent,...

Study reveals uncertainty in how much carbon...

April 5, 2021

The ocean’s “biological pump” describes the many marine processes that work to take up carbon dioxide from the atmosphere and transport it deep into the ocean, where it can remain sequestered for centuries. This ocean pump is a powerful regulator of atmospheric carbon dioxide and an essential ingredient in any global climate forecast. But a new MIT study points to a significant uncertainty in the way the biological pump is represented in climate models today. Researchers found that the...

An artificial intelligence tool that can help...

April 2, 2021

Melanoma is a type of malignant tumor responsible for more than 70 percent of all skin cancer-related deaths worldwide. For years, physicians have relied on visual inspection to identify suspicious pigmented lesions (SPLs), which can be an indication of skin cancer. Such early-stage identification of SPLs in primary care settings can improve melanoma prognosis and significantly reduce treatment cost. The challenge is that quickly finding and prioritizing SPLs is difficult, due to the high volume of pigmented lesions that...

Reinventing the graduate student community during a...

April 2, 2021

A year since the pandemic upended the day-to-day lives of the MIT community and in-person instruction turned into virtual Zoom classes, students have gone above and beyond to create and nurture connections with one another through creative and interactive programs and initiatives. For the Sidney Pacific graduate community, members of house government have steadily and successfully developed their own virtual community — to connect those who are physically away, as well as those who remained on campus. “We wanted...

3 Questions: Emma Teng on anti-Asian American...

April 2, 2021

A string of murders and violent attacks against Asian Americans has jolted the U.S. over the last year. As shocking as these incidents are, they are not novel. Asian Americans and Asian immigrants have long had to contend with physical attacks and discrimination, something evident in the research of Emma Teng, the T.T. and Wei Fong Chao Professor of Asian Civilizations at MIT, and author of the 2013 book “Eurasian: Mixed Identities in the United States, China, and Hong...

A streamlined approach to determining thermal properties...

April 1, 2021

In a September 2020 essay in Nature Energy, three scientists posed several “grand challenges” — one of which was to find suitable materials for thermal energy storage devices that could be used in concert with solar energy systems. Fortuitously, Mingda Li — the Norman C. Rasmussen Assistant Professor of Nuclear Science and Engineering at MIT, who heads the department’s Quantum Matter Group — was already thinking along similar lines. In fact, Li and nine collaborators (from MIT, Lawrence Berkeley National Laboratory,...

A robot that senses hidden objects

April 1, 2021

In recent years, robots have gained artificial vision, touch, and even smell. “Researchers have been giving robots human-like perception,” says MIT Associate Professor Fadel Adib. In a new paper, Adib’s team is pushing the technology a step further. “We’re trying to give robots superhuman perception,” he says. The researchers have developed a robot that uses radio waves, which can pass through walls, to sense occluded objects. The robot, called RF-Grasp, combines this powerful sensing with more traditional computer vision...

Why we need a more precise understanding...

April 1, 2021

As Covid-19 vaccinations continue to be distributed, equity is vital to the process. Vaccination availability for individuals from minority groups is an important issue — partly because of longstanding inequitable access to quality care, and partly because of public sentiment, reflected in polls showing that Black Americans’ mistrust of health care and medical research may influence their feelings about getting vaccinated. Charles Senteio, a health informatics scholar focused on equity and one of MIT’s 2020-21 MLK Visiting Professors, has...

Connecting history with the present moment

March 31, 2021

In spring 2020, as people all over the world confronted the daily reality of living through the Covid-19 pandemic, many wondered how previous generations of humans navigated similar crises. At MIT, an interdisciplinary team of humanistic faculty decided to explore this question in a course that broke ground as a live, free MIT class, held in an open public webinar format so that anyone who wanted to attend could do so, from anywhere in the world. As the course...

How industrialized life remodels the microbiome

March 31, 2021

Thousands of different bacterial species live within the human gut. Most are beneficial, while others can be harmful. A new study from an MIT-led team has revealed that these bacterial populations can remake themselves within the lifetime of their host, by passing genes back and forth. The researchers also showed that this kind of gene transfer occurs more frequently in the microbiomes of people living in industrialized societies, possibly in response to their specific diets and lifestyles. “One unexpected...
