Lessons from teaching about the pandemic in...
Just a few months after the Covid-19 pandemic took hold, Alan Grossman was already mulling over an idea for a new class to help people make sense of the virus. As head of MIT’s Department of Biology, he was aware of the key role fundamental research would play in the coming months. From RNA viruses and genomic sequencing to antibodies and vaccines, MIT students and the general public would need reliable scientific information to understand the evolving situation —...

Improving the way videos are organized
At any given moment, many thousands of new videos are being posted to sites like YouTube, TikTok, and Instagram. An increasing number of those videos are being recorded and streamed live. But tech and media companies still struggle to understand what’s going in all that content. Now MIT alumnus-founded Netra is using artificial intelligence to improve video analysis at scale. The company’s system can identify activities, objects, emotions, locations, and more to organize and provide context to videos in new...

Does correcting online falsehoods make matters worse?
So, you thought the problem of false information on social media could not be any worse? Allow us to respectfully offer evidence to the contrary. Not only is misinformation increasing online, but attempting to correct it politely on Twitter can have negative consequences, leading to even less-accurate tweets and more toxicity from the people being corrected, according to a new study co-authored by a group of MIT scholars. The study was centered around a Twitter field experiment in which...

Scene at MIT: Setting up camp under...
It sounds like a prank — a tent pitched under the Great Dome in the middle of the Barker Library Reading Room. But this tent was all library business, erected to provide the Institute community access to materials critical for teaching and research. Last August, after MIT Distinctive Collections was displaced from Building 14 to Barker Library due to the Hayden Library renovation, they set up work spaces along the perimeter of the Great Dome to allow staff to...

MIT.nano launches START.nano accelerator
MIT.nano has announced a new pilot program, START.nano, to support hard-tech ventures in their early stages. Seven companies with nanoscale technologies at the core of their business have been accepted to the program. For 2021, the primary benefit for the START.nano participants will be discounted access to MIT.nano’s cleanrooms, characterization tools, and other laboratories. MIT.nano’s staff will use the pilot year to explore with the companies what programmatic support START.nano can incorporate to boost the success of hard-tech ventures....

Susan Solomon, scholar of atmospheric chemistry and...
Susan Solomon, an atmospheric chemist whose work explaining the Antarctic ozone hole informed international policy, has received the 2020-2021 James R. Killian, Jr. Faculty Achievement Award. The highest such honor at the Institute, the award was established in 1971 to honor Killian, who served as MIT’s 10th president from 1948 to 1959, and chair of the MIT Corporation from 1959 to 1971. As this year’s recipient, Solomon on April 14 delivered a one-hour lecture in which she touched on...

Behind Covid-19 vaccine development
When starting a vaccine program, scientists generally have anecdotal understanding of the disease they’re aiming to target. When Covid-19 surfaced over a year ago, there were so many unknowns about the fast-moving virus that scientists had to act quickly and rely on new methods and techniques just to even begin understanding the basics of the disease. Scientists at Janssen Research & Development, developers of the Johnson & Johnson-Janssen Covid-19 vaccine, leveraged real-world data and, working with MIT researchers, applied...

Ozone-depleting chemicals may spend less time in...
MIT scientists have found that ozone-depleting chlorofluorocarbons, or CFCs, stay in the atmosphere for a shorter amount of time than previously estimated. Their study suggests that CFCs, which were globally phased out in 2010, should be circulating at much lower concentrations than what has recently been measured. The new results, published today in Nature Communications, imply that new, illegal production of CFCs has likely occurred in recent years. Specifically, the analysis points to new emissions of CFC-11, CFC-12, and...

Helping students of all ages flourish in...
A new cross-disciplinary research initiative at MIT aims to promote the understanding and use of AI across all segments of society. The effort, called Responsible AI for Social Empowerment and Education (RAISE), will develop new teaching approaches and tools to engage learners in settings from preK-12 to the workforce. “People are using AI every day in our workplaces and our private lives. It’s in our apps, devices, social media, and more. It’s shaping the global economy, our institutions, and...

Global Languages announces new HASS concentration in...
Students at MIT will now be able to take their Humanities, Arts, and Social Sciences concentration in Korean. The new concentration extends the options for Asian languages at MIT, which also include Japanese and Mandarin. In response to long-term student demand and the growing importance of international activities in Korea, MIT Global Languages identified Korean as a key area of strategic growth in 2016. Following a successful four-year pilot, Korean was added to the Global Languages curriculum in 2020,...

Ice melts on US-Sudan relations, providing new...
It was over 27 years in the making. When the White House removed Sudan from the “State Sponsors of Terrorism” list in December 2020, ZAHARA for Education was ready. ZAHARA was founded by MIT technology and policy master’s student Ilham Ali and Harvard University alumna Sahar Omer to expand educational opportunities between Sudan and the United States. Earlier this year, the organization partnered with MIT-Africa, an MIT International Science and Technology Initiatives (MISTI) program, to launch the first-ever Global...

3 Questions: President Reif on the search...
Earlier this month, President L. Rafael Reif announced that Cynthia Barnhart SM ’86, PhD ’88, MIT’s chancellor since 2014, will step down this summer. Following a sabbatical leave, she’ll return to teaching and research. At MIT, the chancellor has responsibility for “all things students”: graduate and undergraduate education, student life, student services, and other areas that affect the student experience. In sharing the news of Chancellor Barnhart’s decision, President Reif wrote that he has launched a search to fill...

Supermassive black holes devour gas just like...
On Sept. 9, 2018, astronomers spotted a flash from a galaxy 860 million light years away. The source was a supermassive black hole about 50 million times the mass of the sun. Normally quiet, the gravitational giant suddenly awoke to devour a passing star in a rare instance known as a tidal disruption event. As the stellar debris fell toward the black hole, it released an enormous amount of energy in the form of light. Researchers at MIT, the...

Dynamic thinking about management problems
It’s a familiar story. Tens of millions of U.S. workers toil away in insecure, low-paid jobs in retail and services. It seems clear why companies keep wages low: more profits for ownership. Yet several successful firms in these industries — Costco, Trader Joe’s, QuikTrip — pay workers more and are still very profitable. Why don’t more companies try this? The answer isn’t simple. But that’s why it interests Hazhir Rahmandad, an associate professor at the MIT Sloan School of...
