Trying to put the brakes on car...

June 8, 2021

To limit pollution and traffic congestion in Beijing, officials in 2011 imposed a citywide restriction on the number of automobiles residents can purchase annually. That policy has helped limit car sales and emissions. But the system has a loophole: Beijing residents have been going elsewhere in China to purchase cars, then bringing them home. As a new study co-authored by MIT scholars finds, this policy “leakage” reduces the intended impact of the car-restriction system by about 35 percent. So,...

2021 MITx Prize winners build community on...

June 7, 2021

On May 14, six MIT instructors were honored with the 2021 MITx Prize for Teaching and Learning in MOOCs. The prize, established in 2016, honors excellence in creating Massive Open Online Courses (MOOCs) for MITx on edX. Anyone in the MIT community can submit nominations, including MITx MOOC creators, and awardees are selected by the MITx Faculty Advisory Committee. The award was given to two courses this year, honoring faculty and instructors from four disciplines. Jonathan Gruber, Ford Professor of...

Visualizing cement hydration on a molecular level

June 7, 2021

The concrete world that surrounds us owes its shape and durability to chemical reactions that start when ordinary Portland cement is mixed with water. Now, MIT scientists have demonstrated a way to watch these reactions under real-world conditions, an advance that may help researchers find ways to make concrete more sustainable. The study is a “Brothers Lumière moment for concrete science,” says co-author Franz-Josef Ulm, professor of civil and environmental engineering and faculty director of the MIT Concrete Sustainability...

Tiny particles power chemical reactions

June 7, 2021

MIT engineers have discovered a new way of generating electricity using tiny carbon particles that can create a current simply by interacting with liquid surrounding them. The liquid, an organic solvent, draws electrons out of the particles, generating a current that could be used to drive chemical reactions or to power micro- or nanoscale robots, the researchers say. “This mechanism is new, and this way of generating energy is completely new,” says Michael Strano, the Carbon P. Dubbs Professor...

“Commit to changing the world,” civil rights...

June 4, 2021

For only the second time in its history, MIT celebrated its Commencement in an online ceremony. This year’s event featured taped tributes from around the world, a musical composition created specially for the event, and a moving and deeply personal address from civil rights lawyer Bryan Stevenson. In the hourlong webcast, 1,027 undergraduates and 2,271 graduate students were awarded their degrees — some of them, for the first time, instantly receiving electronic versions of the hard-earned credential. In his...

Professor Sangeeta Bhatia’s salute from the faculty

June 4, 2021

Below is the salute to the graduates, as prepared for delivery, by Sangeeta Bhatia SM ’93 PhD ’97, the John J. and Dorothy Wilson Professor of Engineering, for the Institute’s 2021 Commencement, held online today. MIT PhD class of 2021, you did it! You have managed to get over the finish line in a race with obstacles that none of us could have imagined when you started. Institute closing. Remote learning. Research on a shift schedule. In a year of...

On systemic sources of early life stress,...

June 3, 2021

A powerful series of speakers at the Picower Institute for Learning and Memory’s biennial Spring Symposium, Early Life Stress and Mental Health, blended personal stories and rigorous research to demonstrate that while remedying the lifelong toxic stress and disadvantage many people incur during childhood can be difficult, it is by no means intractable. Picower Institute Director Li-Huei Tsai opened the symposium, co-produced with the JPB Foundation led by Barbara Picower, with the observation that while problems such as poverty,...

Exploring the future of humanitarian technology

June 3, 2021

The year 2030 serves as the resolution to the United Nation’s Agenda for Sustainable Development. The agenda, adopted in 2015 by all UN member states including the United States, mobilizes global efforts to protect the planet, end poverty, foster peace, and safeguard the rights of all people. Nine years out from the target date, the sustainable development goals of the agenda still remain ambitious, and as relevant as ever. MIT Lincoln Laboratory has been growing its efforts to provide...

Experiential learning through entrepreneurship

June 3, 2021

As senior Gabrielle Finear was pursuing a major in computer science, economics, and data science, she wanted to find a way to apply what she was learning. “I found my major to be incredibly theoretical. Although my coursework provided me with an excellent educational foundation, I didn’t want to graduate without ever having built anything,“ Finear explains. In the spring of her sophomore year, Finear and a friend applied to the MIT Sandbox Innovation Fund Program as team Snack...

William Dalzell, influential lecturer in chemical engineering...

June 3, 2021

William H. Dalzell ’58, SM ’60, ScD ’65, a longtime lecturer in chemical engineering at MIT and station director for the David H. Koch School of Chemical Engineering Practice, passed away on April 13 after a protracted battle with cancer. He was 84 years old. The first person in his family to attend college, Dalzell entered MIT in 1954. In an essay for the MIT Office of the First Year, he recalled humorously, “I had no idea what I...

Engineers create a programmable fiber

June 3, 2021

MIT researchers have created the first fiber with digital capabilities, able to sense, store, analyze, and infer activity after being sewn into a shirt. Yoel Fink, who is a professor in the departments of materials science and engineering and electrical engineering and computer science, a Research Laboratory of Electronics principal investigator, and the senior author on the study, says digital fibers expand the possibilities for fabrics to uncover the context of hidden patterns in the human body that could be...

A better way to introduce digital tech...

June 3, 2021

When bringing technologies into the workplace, it pays to be realistic. Often, for instance, bringing new digital technology into an organization does not radically improve a firm’s operations. Despite high-level planning, a more frequent result is the messy process of frontline employees figuring out how they can get tech tools to help them to some degree. That task can easily fall on overburdened workers who have to grapple with getting things done, but don’t always have much voice in...

Q&A: Meditation for Chinese language learners

June 2, 2021

With the onset of the Covid-19 pandemic, student well-being has become a pressing issue for many instructors. In this interview, Panpan Gao and Kang Zhou, lecturers in Chinese at MIT Global Languages, discuss their project to produce original meditation videos tailored for Chinese language learners. Working with a team of collaborators, they launched their website Meditation for Chinese Learners. The team has just received funding from MIT’s MindHandHeart Community Innovation Fund to further expand the project for the coming...

How data science gives new insight into...

June 2, 2021

“To do really important research in environmental policy,” said Francesca Dominici, “the first thing we need is data.” Dominici, a professor of biostatistics at the Harvard T.H. Chan School of Public Health and co-director of the Harvard Data Science Initiative, recently presented the Henry W. Kendall Memorial Lecture at MIT. She described how, by leveraging massive amounts of data, Dominici and a consortium of her colleagues across the nation are revealing, on a grand scale, the effects air pollution...

3D printing tiny parts for big impact

June 2, 2021

Whether it’s computer chips, smartphone components, or camera parts, the hardware in many products is constantly getting smaller. The trend is pushing companies to come up with new ways to make the parts that power our world. Enter Boston Micro Fabrication (BMF). The company was co-founded by MIT Professor Nicholas Fang in 2016 to improve the resolution and precision of 3D printing. Today BMF is helping customers in the race toward ever smaller parts by offering new kinds of...
