Astronomers discover a rare “black widow” binary,...
The flashing of a nearby star has drawn MIT astronomers to a new and mysterious system 3,000 light years from Earth. The stellar oddity appears to be a new “black widow binary” — a rapidly spinning neutron star, or pulsar, that is circling and slowly consuming a smaller companion star, as its arachnid namesake does to its mate. Astronomers know of about two dozen black widow binaries in the Milky Way. This newest candidate, named ZTF J1406+1222, has the...

Artificial intelligence system learns concepts shared across...
Humans observe the world through a combination of different modalities, like vision, hearing, and our understanding of language. Machines, on the other hand, interpret the world through data that algorithms can process. So, when a machine “sees” a photo, it must encode that photo into data it can use to perform a task like image classification. This process becomes more complicated when inputs come in multiple formats, like videos, audio clips, and images. “The main challenge here is, how...

Absent legislative victory, the president can still...
The most recent United Nations climate change report indicates that without significant action to mitigate global warming, the extent and magnitude of climate impacts — from floods to droughts to the spread of disease — could outpace the world’s ability to adapt to them. The latest effort to introduce meaningful climate legislation in the United States Congress, the Build Back Better bill, has stalled. The climate package in that bill — $555 billion in funding for climate resilience and...

Why bother with subject-verb agreement?
If you are in Bucharest and impatiently waiting for, say, your children to head off to school in the morning, you might hear yourself saying something like, “Haideţi caţi întârziat, ce mai!” Or: “Obviously, you are late!” Uttering that sentence might not actually spur anyone into action. But in the process, it might provide interesting evidence about the way everyday language works. MIT linguist Shigeru Miyagawa contends that it does just that, in a new book exploring the function...

MIT Research Slam showcases postdoc and PhD...
Can you tell the story of a complex research project in only three minutes? Could a presentation emerge from extreme time compression transformed like a diamond from coal? The MIT Research Slam Public Showcase on April 11 put these questions and more center stage as the four postdoc and five PhD student finalists competed for cash prizes.  The ability to compellingly pitch scientific research to a smart but non-specialized audience is a bankable skill central to success in any...

A single memory is stored across many...
A new study by scientists at The Picower Institute for Learning and Memory at MIT provides the most comprehensive and rigorous evidence yet that the mammalian brain stores a single memory across a widely distributed, functionally connected complex spanning many brain regions, rather than in just one or even a few places. Memory pioneer Richard Semon had predicted such a “unified engram complex” more than a century ago, but achieving the new study’s affirmation of his hypothesis required the...

Secret superheroes of EECS
MIT’s Department of Electrical Engineering and Computer Science is a crucible for technological innovation, but one of the most important aspects of the program’s leading global status has nothing to do with computers or circuits, artificial intelligence, or algorithms. It has to do with an elite group of educators who have dedicated their careers to ensuring that the technology, curriculum, and instructional delivery of MIT’s classroom education all keep up with the dizzying pace of its research. They’re called:...

A one-up on motion capture
From “Star Wars” to “Happy Feet,” many beloved films contain scenes that were made possible by motion capture technology, which records movement of objects or people through video. Further, applications for this tracking, which involve complicated interactions between physics, geometry, and perception, extend beyond Hollywood to the military, sports training, medical fields, and computer vision and robotics, allowing engineers to understand and simulate action happening within real-world environments. As this can be a complex and costly process — often...

Engineers use artificial intelligence to capture the...
Waves break once they swell to a critical height, before cresting and crashing into a spray of droplets and bubbles. These waves can be as large as a surfer’s point break and as small as a gentle ripple rolling to shore. For decades, the dynamics of how and when a wave breaks have been too complex to predict. Now, MIT engineers have found a new way to model how waves break. The team used machine learning along with data...

Material designed to improve power plant efficiency...
The winner of this year’s Water Innovation Prize is a company commercializing a material that could dramatically improve the efficiency of power plants. The company, Mesophase, is developing a more efficient power plant steam condenser that leverages a surface coating developed in the lab of Evelyn Wang, MIT’s Ford Professor of Engineering and the head of the Department of Mechanical Engineering. Such condensers, which convert steam into water, sit at the heart of the energy extraction process in most...

In 2014, Arun Cherian returned to his home country of India to help his sister with her wedding. By that time Cherian had earned his master’s in mechanical engineering at Columbia University, spent four years as a researcher at the University of California at Berkeley, and was pursuing his PhD at Purdue University, where he was studying the biomechanics of human locomotion. He looked over his childhood home with the fresh perspective of someone who has spent the better...

Seven from MIT elected to American Academy...
Seven MIT faculty members are among more than 250 leaders from academia, the arts, industry, public policy, and research elected to the American Academy of Arts and Sciences, the academy announced Thursday. One of the nation’s most prestigious honorary societies, the academy is also a leading center for independent policy research. Members contribute to academy publications, as well as studies of science and technology policy, energy and global security, social policy and American institutions, the humanities and culture, and...

MIT announces plans for presidential search
Diane Greene, the chair of the MIT Corporation, announced today in a letter to the MIT community that MIT’s presidential search committee had been formed and is ready to start a thorough and broad-based search to find the successor to President L. Rafael Reif, who in February announced his plans to step down at the end of this year.  “Overseeing the selection of MIT’s next president is the Corporation’s most important responsibility. As we initiate the search process, we...

How can we reduce the carbon footprint...
The voracious appetite for energy from the world’s computers and communications technology presents a clear threat for the globe’s warming climate. That was the blunt assessment from presenters in the intensive two-day Climate Implications of Computing and Communications workshop held on March 3 and 4, hosted by MIT’s Climate and Sustainability Consortium (MCSC), MIT-IBM Watson AI Lab, and the Schwarzman College of Computing. The virtual event featured rich discussions and highlighted opportunities for collaboration among an interdisciplinary group of...

Aging Brain Initiative awards fund five new...
Neurodegenerative diseases are defined by an increasingly widespread and debilitating death of nervous system cells, but they also share other grim characteristics: Their cause is rarely discernible and they have all eluded cures. To spur fresh, promising approaches and to encourage new experts and expertise to join the field, MIT’s Aging Brain Initiative (ABI) this month awarded five seed grants after a competition among labs across the Institute. Founded in 2015 by nine MIT faculty members, the ABI promotes...
