MIT startup has big plans to pull...

November 1, 2023

In order to avoid the worst effects of climate change, the United Nations has said we’ll need to not only reduce emissions but also remove carbon dioxide from the atmosphere. One method for achieving carbon removal is direct air capture and storage. Such technologies are still in their infancy, but many efforts are underway to scale them up quickly in hopes of heading off the most catastrophic effects of climate change. The startup Noya, founded by Josh Santos ’14,...

Steven Barrett named head of the Department...

October 31, 2023

Steven Barrett, the H.N. Slater Professor of Aeronautics and Astronautics, has been named the new head of the Department of Aeronautics and Astronautics (AeroAstro), effective Nov. 1. “Professor Barrett is incredibly well-suited to serve as leader of the Department of Aeronautics and Astronautics. Having served as associate department head since 2021 and interim department head for the past five months, he has demonstrated a commitment to the AeroAstro community,” says Anantha Chandrakasan, dean of the MIT School of Engineering...

A new record for Math Prize for...

October 30, 2023

Florida Virtual School senior Jessica Wan was the winner of the 15th Math Prize for Girls (MP4G) annual contest for female-identifying contestants, held Oct. 6-8 at MIT. She scored 17 out of 20 questions, which added up to make Wan the MP4G’s most successful contestant in its history; she also won the contest last year and in 2019, as an eighth grader. (MP4G paused for two years at the height of the Covid-19 pandemic.) Because Wan had won $82,000...

Engineers develop an efficient process to make...

October 30, 2023

The search is on worldwide to find ways to extract carbon dioxide from the air or from power plant exhaust and then make it into something useful. One of the more promising ideas is to make it into a stable fuel that can replace fossil fuels in some applications. But most such conversion processes have had problems with low carbon efficiency, or they produce fuels that can be hard to handle, toxic, or flammable. Now, researchers at MIT and...

New techniques efficiently accelerate sparse tensors for...

October 30, 2023

Researchers from MIT and NVIDIA have developed two techniques that accelerate the processing of sparse tensors, a type of data structure that’s used for high-performance computing tasks. The complementary techniques could result in significant improvements to the performance and energy-efficiency of systems like the massive machine-learning models that drive generative artificial intelligence. Tensors are data structures used by machine-learning models. Both of the new methods seek to efficiently exploit what’s known as sparsity — zero values — in the...

The brain may learn about the world...

October 30, 2023

To make our way through the world, our brain must develop an intuitive understanding of the physical world around us, which we then use to interpret sensory information coming into the brain. How does the brain develop that intuitive understanding? Many scientists believe that it may use a process similar to what’s known as “self-supervised learning.” This type of machine learning, originally developed as a way to create more efficient models for computer vision, allows computational models to learn...

3 Questions: A roadmap toward circularity in...

October 27, 2023

In March 2022, representatives of global footwear brands gathered with sustainability experts and other academic researchers on the MIT campus. The mission? To kick-start a discussion on addressing the waste produced by the footwear industry. An MIT research project arising from the Circular Shoe Systems Summit has now resulted in a white paper titled the Footwear Manifesto. The report is co-authored by Yuly Fuentes-Medel, as MIT’s Fabric Innovation Hub manager and now program director of textiles at MIT Climate...

MIT’s Justin Yu wins Classic Tetris World...

October 27, 2023

If you have 59 seconds to devote to pure joy, you won’t regret watching this video clip of Justin “Fractal” Yu, an MIT junior who, on Oct. 15, became the top classic Tetris player in the world by winning the 2023 Classic Tetris World Championships. The computer science and engineering major from Dallas, Texas, plans to double major in math with a minor in music technology. Despite his busy schedule, he still finds time to play the cello in...

Turning engineers into well-rounded communicators

October 27, 2023

For MIT engineering students and postdocs, tasks like writing grant proposals, applying to jobs, and presenting research findings require not only technical expertise but also the ability to clearly communicate. For the last 10 years, the MIT School of Engineering’s Communication Lab has helped students and postdocs develop those communication skills. Using principles like understanding your audience, identifying your purpose, and presenting a single, overarching theme, the lab’s students have advanced their academic and professional careers. “Learning communications ideas...

A marvel in masonry shows the art...

October 27, 2023

In the Hudson River Valley, on a hill inside the Storm King Art Center, a new addition to the country’s leading outdoor sculpture collection was unveiled this fall. “Lookout,” by the eminent American sculptor Martin Puryear, is a beguiling, domed brick structure with confounding curves, a walk-in entrance, and 90 apertures. The sculpture “could be the most amazing thing Martin’s ever done,” the noted curator John Elderfield told The New York Times. “Lookout” also raises a question: How do...

Books under attack, then and now

October 26, 2023

Richard Ovenden was dressed appropriately for the start of Banned Books Week. He proudly displayed the American Library Association’s “Free people read freely” T-shirt as he approached the podium at Hayden Library on Oct. 2. Ovenden, Bodley’s Librarian at the University of Oxford, spoke about the willful destruction of recorded knowledge for an event titled “Book Wars,” the inaugural event in a new series called Conversations on Academic Freedom and Expression (CAFE), a collaboration between the MIT Libraries and...

Making genetic prediction models more inclusive

October 26, 2023

While any two human genomes are about 99.9 percent identical, genetic variation in the remaining 0.1 percent plays an important role in shaping human diversity, including a person’s risk for developing certain diseases. Measuring the cumulative effect of these small genetic differences can provide an estimate of an individual’s genetic risk for a particular disease or their likelihood of having a particular trait. However, the majority of models used to generate these “polygenic scores” are based on studies done...

Shape-shifting fiber can produce morphing fabrics

October 26, 2023

Instead of needing a coat for each season, imagine having a jacket that would dynamically change shape so it becomes more insulating to keep you warm as the temperature drops. A programmable, actuating fiber developed by an interdisciplinary team of MIT researchers could someday make this vision a reality. Known as FibeRobo, the fiber contracts in response to an increase in temperature, then self-reverses when the temperature decreases, without any embedded sensors or other hard components. Play video The...

Eight high school teams named Lemelson-MIT InvenTeams...

October 25, 2023

The Lemelson-MIT Program has announced the 2023-24 InvenTeams, eight teams of high school students, teachers, and mentors from across the country who each will receive $7,500 in grant funding and other support to build a technological invention to solve a problem of their own choosing. The students’ inventions are inspired by real-world problems they identified in their local communities. Meet the 2023–24 InvenTeams The InvenTeams were selected by a panel consisting of university professors, inventors, entrepreneurs, industry professionals, and...

Bright flash leads astronomers to a heavy-metal...

October 25, 2023

An extraordinary burst of high-energy light in the sky has pointed astronomers to a pair of metal-forging neutron stars 900 million light years from Earth. In a study appearing today in Nature, an international team of astronomers, including scientists at MIT, reports the detection of an extremely bright gamma-ray burst (GRB), which is the most powerful type of explosion known in the universe. This particular GRB is the second-brightest so far detected, and the astronomers subsequently traced the burst’s...
