Fostering media literacy in the age of...
While people turn to digital media for news at high rates, algorithms for manipulating media continue to grow more powerful. In a Pew Research Center survey (August/September 2020), 53 percent of adults in the United States say they get news from social media “often” or “sometimes.” People have long been aware of phenomena such as “doctored” photos and misinformation at large, but machine learning is enabling the proliferation of “deepfakes,” videos or images of fake events with increasing sophistication. Now,...

Advancing public understanding of sea-level rise
Museum exhibits can be a unique way to communicate science concepts and information. Recently, MIT faculty have served as sounding boards for curators at the Museum of Science, Boston, a close neighbor of the MIT campus. In January, Professor Emerita Paola Malanotte-Rizzoli and Cecil and Ida Green Professor Raffaele Ferrari of the Department of Earth, Atmospheric and Planetary Science (EAPS) visited the museum to view the newly opened pilot exhibit, “Resilient Venice: Adapting to Climate Change.” When Malanotte-Rizzoli was...

A life-changing fertilizer for rural farmers in...
Most commercial fertilizer travels a long way before it reaches rural farmers in Kenya. Transportation costs force many farmers to rely on cheap, synthetic fertilizers, which can lead to the acidification and degradation of their soil over time. The situation amounts to a multigenerational crisis as elders have watched their crop yields dwindle over the course of decades. Now Safi Organics is using a technology honed at MIT’s D-Lab to make organic fertilizer that can help restore such farmlands....

At this year’s annual MIT celebration of the life and work of Martin Luther King Jr, keynote speaker Eddie S. Glaude Jr., the James S. Donnell Distinguished University Professor at Princeton University, invoked King’s memory in an impassioned appeal for confronting the realities of the United States’ history and the country’s racist beliefs and actions, in order to achieve a more just and equitable nation. Glaude, a prominent political commentator and author of books including “Democracy in Black: How...

Nurturing human communities and natural ecosystems
When she was in 7th grade, Heidi Li and the five other members of the Oyster Gardening Club cultivated hundreds of oysters to help repopulate the Chesapeake Bay. On the day they released the oysters into the bay, the event attracted TV journalists and local officials, including the governor. The attention opened the young Li’s eyes to the ways that a seemingly small effort in her local community could have a real-world impact. “I got to see firsthand how...

Mathematician George Lusztig receives Wolf Prize
George Lusztig, the Abdun-Nur Professor of Mathematics at MIT, has been awarded the prestigious 2022 Wolf Prize in Mathematics for his work on geometric representation theory and algebraic groups. The Israel-based Wolf Foundation cited the American-Romanian mathematician “for groundbreaking contributions to representation theory and related areas.” Lusztig is known for his work on representation theory, in particular for the objects closely related to algebraic groups, such as finite reductive groups, Hecke algebras, p-adic groups, quantum groups, and Weyl groups.  ...

Solar-powered system offers a route to inexpensive...
An estimated two-thirds of humanity is affected by shortages of water, and many such areas in the developing world also face a lack of dependable electricity. Widespread research efforts have thus focused on ways to desalinate seawater or brackish water using just solar heat. Many such efforts have run into problems with fouling of equipment caused by salt buildup, however, which often adds complexity and expense. Now, a team of researchers at MIT and in China has come up...

A new atlas of cells that carry...
While neurons and glial cells are by far the most numerous cells in the brain, many other types of cells play important roles. Among those are cerebrovascular cells, which form the blood vessels that deliver oxygen and other nutrients to the brain. Those cells, which comprise only 0.3 percent of the brain’s cells, also make up the blood-brain barrier, a critical interface that prevents pathogens and toxins from entering the brain, while allowing critical nutrients and signals through. Researchers...

Student-led MIT course provides an inside look...
Jeana Choi and Lisa Yoo had already bonded over their appreciation for Korean music when they decided to organize a K-pop course at MIT during the Institute’s Independent Activities Period (IAP) this January. Both graduating fifth-year master’s students in electrical engineering and computer science, Choi and Yoo became friends in class 21M.294 (Popular Musics of the World), where they collaborated on a podcast-style interview with a producer of Korean R&B.  Choi, who had previously run an IAP course about...

Adopting a holistic approach to problem-solving in...
“Price discounting is one of my pet peeves,” says Sharmila Chatterjee. No, the academic head for the Enterprise Management (EM) Track of MIT Sloan School of Management’s MBA program doesn’t have it out for customers looking for a deal. Rather, this is a stitch in a running thread of conversation about bigger-picture thinking honed from years of research. Chatterjee is a business-to-business (B2B) marketing expert and an award-winning case writer who examines issues in the domains of channels of...

ClassPass makes health and fitness more accessible
Are you a Pilates person or a cycling person? Maybe you’re a HIIT person who’s convinced themselves they’re only interested in dance. Maybe you like to mix it up throughout the week. Maybe you simply don’t know yet. It’s hard to predict what kind of workout or wellness class will work best for you on any given day. Many conventional memberships or studios also require commitments that can be daunting if you’re still figuring out what your ideal fitness...

“Traveling” nature of brain waves may help...
After more than a century of study, the significance of brain waves — the coordinated, rhythmic electrical activity of groups of brain cells — is still not fully known. An especially underappreciated aspect of the phenomenon is that waves spatially propagate, or “travel,” through brain regions over time. A new study by researchers at The Picower Institute for Learning and Memory at MIT measured how waves travel in the brain’s prefrontal cortex during working memory to investigate the functional...
