MIT’s Science Policy Initiative holds 14th annual...

November 26, 2024

From Oct. 21 to 22, a delegation of 21 MIT students and one postdoc met in Washington for the 14th Executive Visit Days (ExVD). Organized by the MIT Science Policy Initiative (SPI) and the MIT Washington Office, ExVD enables students to engage with officials and scientists from federal agencies. Students are given a platform to form connections in the capital while learning about the many facets of science policy work and careers. In two days, the delegation visited eight different...

Troy Van Voorhis to step down as...

November 26, 2024

Troy Van Voorhis, the Robert T. Haslam and Bradley Dewey Professor of Chemistry, will step down as department head of the Department of Chemistry at the end of this academic year. Van Voorhis has served as department head since 2019, previously serving the department as associate department head since 2015. “Troy has been an invaluable partner and sounding board who could always be counted on for a wonderful mix of wisdom and pragmatism,” says Nergis Mavalvala, the Kathleen and...

Is there enough land on Earth to...

November 26, 2024

Capping global warming at 1.5 degrees Celsius is a tall order. Achieving that goal will not only require a massive reduction in greenhouse gas emissions from human activities, but also a substantial reallocation of land to support that effort and sustain the biosphere, including humans. More land will be needed to accommodate a growing demand for bioenergy and nature-based carbon sequestration while ensuring sufficient acreage for food production and ecological sustainability. The expanding role of land in a 1.5...

Decarbonizing heavy industry with thermal batteries

November 26, 2024

Whether you’re manufacturing cement, steel, chemicals, or paper, you need a large amount of heat. Almost without exception, manufacturers around the world create that heat by burning fossil fuels. In an effort to clean up the industrial sector, some startups are changing manufacturing processes for specific materials. Some are even changing the materials themselves. Daniel Stack SM ’17, PhD ’21 is trying to address industrial emissions across the board by replacing the heat source. Since coming to MIT in...

The MIT Press releases report on the...

November 25, 2024

The MIT Press has released a comprehensive report that addresses how open access policies shape research and what is needed to maximize their positive impact on the research ecosystem. The report, entitled “Access to Science and Scholarship 2024: Building an Evidence Base to Support the Future of Open Research Policy,” is the outcome of a National Science Foundation-funded workshop held at the Washington headquarters of the American Association for the Advancement of Science on Sept. 20. While open access...

A blueprint for better cancer immunotherapies

November 25, 2024

Immune checkpoint blockade (ICB) therapies can be very effective against some cancers by helping the immune system recognize cancer cells that are masquerading as healthy cells. T cells are built to recognize specific pathogens or cancer cells, which they identify from the short fragments of proteins presented on their surface. These fragments are often referred to as antigens. Healthy cells will will not have the same short fragments or antigens on their surface, and thus will be spared from...

Improving health, one machine learning system at...

November 25, 2024

Captivated as a child by video games and puzzles, Marzyeh Ghassemi was also fascinated at an early age in health. Luckily, she found a path where she could combine the two interests. “Although I had considered a career in health care, the pull of computer science and engineering was stronger,” says Ghassemi, an associate professor in MIT’s Department of Electrical Engineering and Computer Science and the Institute for Medical Engineering and Science (IMES) and principal investigator at the Laboratory for...

Professor Emeritus James Harris, a scholar of...

November 25, 2024

James Wesley “Jim” Harris PhD ’67, professor emeritus of Spanish and linguistics, passed away on Nov. 10. He was 92. Harris attended the University of Georgia, the Instituto Tecnológico de Estudios Superiores de Monterrey, and the Universidad Nacional Autónoma de México. He later earned a master’s degree in linguistics from Louisiana State University and a PhD in linguistics from MIT. Harris joined the MIT faculty as an assistant professor in 1967, where he remained until his retirement in 1996....

New solar projects will grow renewable energy...

November 25, 2024

In the latest step to implement commitments made in MIT’s Fast Forward climate action plan, staff from the Department of Facilities; Office of Sustainability; and Environment, Health and Safety Office are advancing new solar panel installations this fall and winter on four major campus buildings: The Stratton Student Center (W20), the Dewey Library building (E53), and two newer buildings, New Vassar (W46) and the Theater Arts building (W97). These four new installations, in addition to existing rooftop solar installations...

New AI tool generates realistic satellite images...

November 25, 2024

Visualizing the potential impacts of a hurricane on people’s homes before it hits can help residents prepare and decide whether to evacuate. MIT scientists have developed a method that generates satellite imagery from the future to depict how a region would look after a potential flooding event. The method combines a generative artificial intelligence model with a physics-based flood model to create realistic, birds-eye-view images of a region, showing where flooding is likely to occur given the strength of...

Building an understanding of how drivers interact...

November 22, 2024

As the global conversation around assisted and automated vehicles (AVs) evolves, the MIT Advanced Vehicle Technology (AVT) Consortium continues to lead cutting-edge research aimed at understanding how drivers interact with emerging vehicle technologies. Since its launch in 2015, the AVT Consortium — a global academic-industry collaboration on developing a data-driven understanding of how drivers respond to commercially available vehicle technologies — has developed a data-driven approach to studying consumer attitudes and driving behavior across diverse populations, creating unique, multifaceted,...

Consortium led by MIT, Harvard University, and...

November 22, 2024

MIT is co-leading an effort to enable the development of two new large-scale renewable energy projects in regions with carbon-intensive electrical grids: Big Elm Solar in Bell County, Texas, came online this year, and the Bowman Wind Project in Bowman County, North Dakota, is expected to be operational in 2026. Together, they will add a combined 408 megawatts (MW) of new renewable energy capacity to the power grid. This work is a critical part of MIT’s strategy to achieve...

MIT researchers develop an efficient way to...

November 22, 2024

Fields ranging from robotics to medicine to political science are attempting to train AI systems to make meaningful decisions of all kinds. For example, using an AI system to intelligently control traffic in a congested city could help motorists reach their destinations faster, while improving safety or sustainability. Unfortunately, teaching an AI system to make good decisions is no easy task. Reinforcement learning models, which underlie these AI decision-making systems, still often fail when faced with even small variations...

Advancing urban tree monitoring with AI-powered digital...

November 21, 2024

The Irish philosopher George Berkely, best known for his theory of immaterialism, once famously mused, “If a tree falls in a forest and no one is around to hear it, does it make a sound?” What about AI-generated trees? They probably wouldn’t make a sound, but they will be critical nonetheless for applications such as adaptation of urban flora to climate change. To that end, the novel “Tree-D Fusion” system developed by researchers at the MIT Computer Science and...

A nonflammable battery to power a safer,...

November 21, 2024

Lithium-ion batteries are the workhorses of home electronics and are powering an electric revolution in transportation. But they are not suitable for every application. A key drawback is their flammability and toxicity, which make large-scale lithium-ion energy storage a bad fit in densely populated city centers and near metal processing or chemical manufacturing plants. Now Alsym Energy has developed a nonflammable, nontoxic alternative to lithium-ion batteries to help renewables like wind and solar bridge the gap in a broader...
