Reducing the use of fossil fuels will have unintended consequences for the power-generation industry and beyond. For example, many industrial chemical processes use fossil-fuel byproducts as precursors to things like asphalt, glycerine, and other important chemicals. One solution to reduce the impact of the loss of fossil fuels on industrial chemical processes is to store […]

Providing hands-on photonics education across Massachusetts
Photonics — the science of guiding and manipulating light — enables applications ranging from telecommunications, artificial intelligence, and quantum computing to medical imaging, lidar, and augmented reality displays. But despite the importance of this growing field, the nation faces a shortage of photonics and electronics technicians and engineers. The Lab for Education and Application Prototypes […]
Strengthening students’ knowledge and experience in climate and sustainability
Tackling the climate crisis is central to MIT. Critical to this mission is harnessing the innovation, passion, and expertise of MIT’s talented students, from a variety of disciplines and backgrounds. To help raise this student involvement to the next level, the MIT Climate and Sustainability Consortium (MCSC) recently launched a program that will engage MIT […]
Embracing ancient materials and 21st-century challenges
When Sophia Mittman was 10 years old, she wanted to be an artist. But instead of using paint, she preferred the mud in her backyard. She sculpted it into pots and bowls like the ones she had seen at the archaeological museums, transforming the earthly material into something beautiful. Now an MIT senior studying materials […]
QS World University Rankings rates MIT No. 1 in 12 subjects for 2022
MIT has earned a No. 1 spot in 12 subject areas, according to the QS World University Rankings for 2022, announced today. The Institute received a No. 1 ranking in the following QS subject areas: Architecture/Built Environment; Chemistry; Computer Science and Information Systems; Chemical Engineering; Civil and Structural Engineering; Electrical and Electronic Engineering; Materials Science; […]
MIT graduate engineering, business, science programs ranked highly by U.S. News for 2023
MIT’s graduate program in engineering has again topped the list of U.S. News and World Report’s annual rankings, released today. The program has held the No. 1 spot since 1990, when the magazine first published these rankings. The MIT Sloan School of Management also placed highly, landing in the No. 5 spot for the best […]
Could we make cars out of petroleum residue?
As the world struggles to improve the efficiency of cars and other vehicles in order to curb greenhouse gas emissions and improve the range of electric vehicles, the search is on for ever-lighter materials that are strong enough to be used in the bodies of cars. Lightweight materials made from carbon fiber, similar to the […]
Physicists find direct evidence of strong electron correlation in a 2D material for the first time
In recent years, physicists have discovered materials that are able to switch their electrical character from a metal to an insulator, and even to a superconductor, which is a material in a friction-free state that allows electrons to flow with zero resistance. These materials, which include “magic-angle” graphene and other synthesized two-dimensional materials, can shift […]
A fabric that “hears” your heartbeat
Having trouble hearing? Just turn up your shirt. That’s the idea behind a new “acoustic fabric” developed by engineers at MIT and collaborators at Rhode Island School of Design. The team has designed a fabric that works like a microphone, converting sound first into mechanical vibrations, then into electrical signals, similarly to how our ears […]
Computational modeling guides development of new materials
Metal-organic frameworks, a class of materials with porous molecular structures, have a variety of possible applications, such as capturing harmful gases and catalyzing chemical reactions. Made of metal atoms linked by organic molecules, they can be configured in hundreds of thousands of different ways. To help researchers sift through all of the possible metal-organic framework […]
Toward batteries that pack twice as much energy per pound
In the endless quest to pack more energy into batteries without increasing their weight or volume, one especially promising technology is the solid-state battery. In these batteries, the usual liquid electrolyte that carries charges back and forth between the electrodes is replaced with a solid electrolyte layer. Such batteries could potentially not only deliver twice […]
More sensitive X-ray imaging
Scintillators are materials that emit light when bombarded with high-energy particles or X-rays. In medical or dental X-ray systems, they convert incoming X-ray radiation into visible light that can then be captured using film or photosensors. They’re also used for night-vision systems and for research, such as in particle detectors or electron microscopes. Researchers at […]
Physicists observe an exotic “multiferroic” state in an atomically thin material
MIT physicists have discovered an exotic “multiferroic” state in a material that is as thin as a single layer of atoms. Their observation is the first to confirm that multiferroic properties can exist in a perfectly two-dimensional material. The findings, published today in Nature, pave the way for developing smaller, faster, and more efficient data-storage […]
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 […]
