3 Questions: Exploring the limits of carbon...
As part of a multi-pronged approach toward curbing the effects of greenhouse gas emissions, scientists seek to better understand the impact of rising carbon dioxide (CO2) levels on terrestrial ecosystems, particularly tropical forests. To that end, climate scientist César Terrer, the Class of 1958 Career Development Assistant Professor of Civil and Environmental Engineering (CEE) at MIT, and colleague Josh Fisher of Chapman University are bringing their scientific minds to bear on a unique setting — an active volcano in Costa...

AI system predicts protein fragments that can...
All biological function is dependent on how different proteins interact with each other. Protein-protein interactions facilitate everything from transcribing DNA and controlling cell division to higher-level functions in complex organisms. Much remains unclear, however, about how these functions are orchestrated on the molecular level, and how proteins interact with each other — either with other proteins or with copies of themselves. Recent findings have revealed that small protein fragments have a lot of functional potential. Even though they are...

Professor Anthony Sinskey, biologist, inventor, entrepreneur, and...
Longtime MIT Professor Anthony “Tony” Sinskey ScD ’67, who was also the co-founder and faculty director of the Center for Biomedical Innovation (CBI), passed away on Feb. 12 at his home in New Hampshire. He was 84. Deeply engaged with MIT, Sinskey left his mark on the Institute as much through the relationships he built as the research he conducted. Colleagues say that throughout his decades on the faculty, Sinskey’s door was always open. “He was incredibly generous in...

MIT biologists discover a new type of...
RNA splicing is a cellular process that is critical for gene expression. After genes are copied from DNA into messenger RNA, portions of the RNA that don’t code for proteins, called introns, are cut out and the coding portions are spliced back together. This process is controlled by a large protein-RNA complex called the spliceosome. MIT biologists have now discovered a new layer of regulation that helps to determine which sites on the messenger RNA molecule the spliceosome will...

Rooftop panels, EV chargers, and smart thermostats...
There’s a lot of untapped potential in our homes and vehicles that could be harnessed to reinforce local power grids and make them more resilient to unforeseen outages, a new study shows. In response to a cyber attack or natural disaster, a backup network of decentralized devices — such as residential solar panels, batteries, electric vehicles, heat pumps, and water heaters — could restore electricity or relieve stress on the grid, MIT engineers say. Such devices are “grid-edge” resources...

Chip-based system for terahertz waves could enable...
The use of terahertz waves, which have shorter wavelengths and higher frequencies than radio waves, could enable faster data transmission, more precise medical imaging, and higher-resolution radar. But effectively generating terahertz waves using a semiconductor chip, which is essential for incorporation into electronic devices, is notoriously difficult. Many current techniques can’t generate waves with enough radiating power for useful applications unless they utilize bulky and expensive silicon lenses. Higher radiating power allows terahertz signals to travel farther. Such lenses,...

Reducing carbon emissions from residential heating: A...
In the race to reduce climate-warming carbon emissions, the buildings sector is falling behind. While carbon dioxide (CO2) emissions in the U.S. electric power sector dropped by 34 percent between 2005 and 2021, emissions in the building sector declined by only 18 percent in that same time period. Moreover, in extremely cold locations, burning natural gas to heat houses can make up a substantial share of the emissions portfolio. Therefore, steps to electrify buildings in general, and residential heating...

J-WAFS: Supporting food and water research across...
MIT’s Abdul Latif Jameel Water and Food Systems Lab (J-WAFS) has transformed the landscape of water and food research at MIT, driving faculty engagement and catalyzing new research and innovation in these critical areas. With philanthropic, corporate, and government support, J-WAFS’ strategic approach spans the entire research life cycle, from support for early-stage research to commercialization grants for more advanced projects. Over the past decade, J-WAFS has invested approximately $25 million in direct research funding to support MIT faculty...

MIT community members elected to the National...
Eight MIT researchers are among the 128 new members and 22 international members recently elected to the National Academy of Engineering (NAE) for 2025. Thirteen additional MIT alumni were also elected as new members. One of the highest professional distinctions for engineers, membership in the NAE is given to individuals who have made outstanding contributions to “engineering research, practice, or education, including, where appropriate, significant contributions to the engineering literature” and to “the pioneering of new and developing fields of technology,...

MIT Human Insight Collaborative launches SHASS Faculty...
A new initiative will offer faculty in the MIT School of Humanities, Arts, and Social Sciences (SHASS) the opportunity to participate in a semester-long internal fellows program. The SHASS Faculty Fellows program, administered by the MIT Human Insight Collaborative (MITHIC), will provide faculty with time to focus on their research, writing, or artistic production, and to receive collegial support for the same; to foster social and intellectual community within SHASS, including between faculty and students beyond the classroom; and provide...

Like human brains, large language models reason...
While early language models could only process text, contemporary large language models now perform highly diverse tasks on different types of data. For instance, LLMs can understand many languages, generate computer code, solve math problems, or answer questions about images and audio.    MIT researchers probed the inner workings of LLMs to better understand how they process such assorted data, and found evidence that they share some similarities with the human brain. Neuroscientists believe the human brain has a “semantic...

Unlocking the secrets of fusion’s core with...
Creating and sustaining fusion reactions — essentially recreating star-like conditions on Earth — is extremely difficult, and Nathan Howard PhD ’12, a principal research scientist at the MIT Plasma Science and Fusion Center (PSFC), thinks it’s one of the most fascinating scientific challenges of our time. “Both the science and the overall promise of fusion as a clean energy source are really interesting. That motivated me to come to grad school and work at the PSFC,” he...

Mixing beats, history, and technology
In a classroom on the third floor of the MIT Media Lab, it’s quiet; the disc jockey is setting up. At the end of a conference table ringed with chairs, there are two turntables on either side of a mixer and a worn crossfader. A MacBook sits to the right of the setup. Today’s class — CMS.303/803/21M.365 (DJ History, Technique, and Technology) — takes students to the 1970s, which means disco, funk, rhythm and blues, and the breaks that...
