Everything is a Brand

Glass blowing adapts to Covid-19 protocols

September 23, 2021

Team-based, hands-on activities at MIT have been seriously challenged by the Covid pandemic. This has certainly been true for the W. David Kingery Ceramics and Glass Lab at MIT, where students work in close proximity learning the ancient craft of glass blowing. Practices long considered normal — like sharing blowpipes — suddenly became off-limits in the context of a highly transmissible and health-threatening virus. In September 2020, the Glass Lab received permission to restart limited operations. No students would...

Shaping the future of work

September 23, 2021

If you had told MIT professor Tom Kochan 10 years ago that teaching online courses would forever change his outlook on education, he’d have said, “I don’t think so.” Today, Kochan has come around entirely to the power of thoughtfully constructed online learning experiences after spending six years creating and refining successive iterations of Shaping the Work of the Future, an MITx course that has influenced not only a global audience of tens of thousands of enrollees, but also...

New bionics center established at MIT with...

September 23, 2021

A deepening understanding of the brain has created unprecedented opportunities to alleviate the challenges posed by disability. Scientists and engineers are taking design cues from biology itself to create revolutionary technologies that restore the function of bodies affected by injury, aging, or disease — from prosthetic limbs that effortlessly navigate tricky terrain to digital nervous systems that move the body after a spinal cord injury. With the establishment of the new K. Lisa Yang Center for Bionics, MIT is...

Sylvester James Gates Jr. ’73, PhD ’77...

September 23, 2021

Sylvester James Gates Jr. ’73, PhD ’77 has often described progress on diversity, equity, and inclusion as occurring at “blazingly glacial” rates. The reknowned theoretical physicist was the featured speaker for this year’s MIT Compton Lecture, and he spoke on Tuesday to an appreciative audience, gathered and masked, in Kresge Auditorium. During his address, he chronicled his 52-year career in research, teaching, and service. He also noted moments in history when progress toward advancing civil rights simultaneously surged forward...

Toward a smarter electronic health record

September 23, 2021

Electronic health records have been widely adopted with the hope they would save time and improve the quality of patient care. But due to fragmented interfaces and tedious data entry procedures, physicians often spend more time navigating these systems than they do interacting with patients. Researchers at MIT and the Beth Israel Deaconess Medical Center are combining machine learning and human-computer interaction to create a better electronic health record (EHR). They developed MedKnowts, a system that unifies the processes...

Making health and motion sensing devices more...

September 22, 2021

Previous definitions of “well-being,” limited to taking a brisk walk and eating a few more vegetables, feel in many ways like a distant past. Shiny watches and sleek rings now measure how we eat, sleep, and breathe, calling on a combination of motion sensors and microprocessors to crunch bytes and bits. Even with today’s variety of smart jewelry, clothing, and temporary tattoos that feel equal parts complex and manageable, scientists from MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL)...

Professor Emeritus Ronald Probstein, world-renowned expert in...

September 22, 2021

Ronald Probstein, professor emeritus of mechanical engineering, passed away at the age of 93 on Sept. 19. Probstein, who joined MIT’s faculty in 1962, was a leading expert in fluid mechanics. His research advanced a number of fields including spacecraft design, hypersonic flows, desalination, and the removal of toxic waste from soil. Born and raised in New York City, Probstein worked for the mathematician Richard Courant while studying for his bachelor’s degree at night at New York University. After...

Institute Professor Paula Hammond named to White...

September 22, 2021

Paula Hammond, an MIT Institute Professor and head of MIT’s Department of Chemical Engineering, has been chosen to serve on the President’s Council of Advisors on Science and Technology (PCAST), the White House announced today. The council advises the president on matters involving science, technology, education, and innovation policy. It also provides the White House with scientific and technical information that is needed to inform public policy relating to the U.S. economy, U.S. workers, and national security. “For me,...

3 Questions: An anthropologist and a filmmaker...

September 22, 2021

The steel industry in the U.S. shrank dramatically in the 1970s and 1980s, with profound effects on the country’s industrial workforce. Suddenly, blue-collar workers who had spent their careers in the mills — often as part of multigenerational steelworking families — found themselves unable to earn a living as communities around them suffered and people lost the middle-class lives they had been fashioning. That process was chronicled in MIT anthropologist Christine Walley’s 2013 book “Exit Zero,” a case study...

A new method for removing lead from...

September 22, 2021

Engineers at MIT have developed a new approach to removing lead or other heavy-metal contaminants from water, in a process that they say is far more energy-efficient than any other currently used system, though there are others under development that come close. Ultimately, it might be used to treat lead-contaminated water supplies at the home level, or to treat contaminated water from some chemical or industrial processes. The new system is the latest in a series of applications based...

Data flow’s decisive role on the global...

September 21, 2021

In 2016, Meicen Sun came to a profound realization: “The control of digital information will lie at the heart of all the big questions and big contentions in politics.” A graduate student in her final year of study who is specializing in international security and the political economy of technology, Sun vividly recalls the emergence of the internet “as a democratizing force, an opener, an equalizer,” helping give rise to the Arab Spring. But she was also profoundly struck...

Predicting building emissions across the US

September 21, 2021

The United States is entering a building boom. Between 2017 and 2050, it will build the equivalent of New York City 20 times over. Yet, to meet climate targets, the nation must also significantly reduce the greenhouse gas (GHG) emissions of its buildings, which comprise 27 percent of the nation’s total emissions. A team of current and former MIT Concrete Sustainability Hub (CSHub) researchers is addressing these conflicting demands with the aim of giving policymakers the tools and information...

Bringing precision to musculoskeletal health

September 21, 2021

A clinician investigating a muscle injury will usually start the exam with questions about the patient’s medical history and how they think the injury occurred. The clinician might then place their hands on the injured area and ask the patient to move around. Often, the only quantitative data collected in the process come from asking the patient to use a pain scale from 1 to 10. Compare that to the routine for treating a fever or high blood pressure....

How quickly do algorithms improve?

September 20, 2021

Algorithms are sort of like a parent to a computer. They tell the computer how to make sense of information so they can, in turn, make something useful out of it. The more efficient the algorithm, the less work the computer has to do. For all of the technological progress in computing hardware, and the much debated lifespan of Moore’s Law, computer performance is only one side of the picture. Behind the scenes a second trend is happening: Algorithms...

RNA-targeting enzyme expands the CRISPR toolkit

September 20, 2021

Researchers at MIT’s McGovern Institute for Brain Research have discovered a bacterial enzyme that they say could expand scientists’ CRISPR toolkit, making it easy to cut and edit RNA with the kind of precision that, until now, has only been available for DNA editing. The enzyme, called Cas7-11, modifies RNA targets without harming cells, suggesting that in addition to being a valuable research tool, it provides a fertile platform for therapeutic applications. “This new enzyme is like the Cas9...
