Q&A: More-sustainable concrete with machine learning
As a building material, concrete withstands the test of time. Its use dates back to early civilizations, and today it is the most popular composite choice in the world. However, it’s not without its faults. Production of its key ingredient, cement, contributes 8-9 percent of the global anthropogenic CO2 emissions and 2-3 percent of energy consumption, which is only projected to increase in the coming years. With aging United States infrastructure, the federal government recently passed a milestone bill...

“Vigilant inclusion” central to combating climate change
“To turbocharge work on saving the planet, we need effective, innovative, localized solutions, and diverse perspectives and experience at the table,” said U.S. Secretary of Energy Jennifer M. Granholm, the keynote speaker at the 10th annual U.S. Clean Energy Education and Empowerment (C3E) Women in Clean Energy Symposium and Awards. This event, convened virtually over Nov. 3-4 and engaging more than 1,000 participants, was devoted to the themes of justice and equity in clean energy. In panels and presentations,...

A system for designing and training intelligent...
Let’s say you wanted to build the world’s best stair-climbing robot. You’d need to optimize for both the brain and the body, perhaps by giving the bot some high-tech legs and feet, coupled with a powerful algorithm to enable the climb.  Although design of the physical body and its brain, the “control,” are key ingredients to letting the robot move, existing benchmark environments favor only the latter. Co-optimizing for both elements is hard — it takes a lot of...

Technique enables real-time rendering of scenes in...
Humans are pretty good at looking at a single two-dimensional image and understanding the full three-dimensional scene that it captures. Artificial intelligence agents are not. Yet a machine that needs to interact with objects in the world — like a robot designed to harvest crops or assist with surgery — must be able to infer properties about a 3D scene from observations of the 2D images it’s trained on.      While scientists have had success using neural networks to...

Anantha Chandrakasan awarded 2022 IEEE Mildred Dresselhaus...
Anantha Chandrakasan, dean of the MIT School of Engineering and Vannevar Bush Professor of EECS, has been named the recipient of the 2022 IEEE Mildred Dresselhaus Medal. In the award citation, the IEEE noted Chandrakasan’s “contributions to ultralow-power circuits and systems, and leadership in academia and advancing diversity in the profession.” Anantha Chandrakasan received BS, MS, and PhD degrees in electrical engineering and computer sciences from the University of California at Berkeley, in 1989, 1990, and 1994, respectively. He...

Feast or forage? Study finds circuit that...
MIT neuroscientists have discovered the elegant architecture of a fundamental decision-making brain circuit that allows a C. elegans worm to either forage for food or stop to feast when it finds a source. Capable of integrating multiple streams of sensory information, the circuit employs just a few key neurons to sustain long-lasting behaviors and yet flexibly switch between them as environmental conditions warrant. “For a foraging worm, the decision to roam or to dwell is one that will strongly impact its...

Jelena Vučković delivers 2021 Dresselhaus Lecture on...
As her topic for the 2021 Mildred S. Dresselhaus Lecture, Stanford University professor Jelena Vučković posed a question: Are computers better than humans in designing photonics? Throughout her talk, presented on Nov. 15 in a hybrid format to more than 500 attendees, the Jensen Huang Professor in Global Leadership at Stanford’s School of Engineering offered multiple examples arguing that, yes, computer software can help identify better solutions than traditional methods, leading to smaller, more efficient devices, as well as...

Six MIT students named 2023 Schwarzman Scholars
Five MIT seniors — Sihao Huang, William Kuhl, Giramnah Peña-Alcántara, Sreya Vangara, and Kelly Wu — and graduate student Tingyu Li have been awarded 2022-23 Schwarzman Scholarships. They will head to Tsinghua University in Beijing next August to pursue a one-year master’s degree in global affairs. The students will also receive leadership training, career development, and opportunities to gain a greater understanding of China’s role in the world. The Schwarzman Scholars program aims to build a network of young...

Taking some of the guesswork out of...
In their quest to discover effective new medicines, scientists search for drug-like molecules that can attach to disease-causing proteins and change their functionality. It is crucial that they know the 3D shape of a molecule to understand how it will attach to specific surfaces of the protein. But a single molecule can fold in thousands of different ways, so solving that puzzle experimentally is a time consuming and expensive process akin to searching for a needle in a molecular...

Q&A: David Autor on the long afterlife...
In 2001, the U.S. normalized long-term trade relations with China, and China joined the World Trade Organization — moves many expected to help both economies. Instead, over the next several years, inexpensive imports from China significantly undercut U.S. manufacturing, especially in industries such as textiles and furniture-making. By 2011, this “China shock” from trade was responsible for the loss of 1 million U.S. manufacturing jobs, and 2.4 million jobs overall. Many locales were especially hard hit, especially in the...

Helping people understand and track their health
About half of all women over 50 will experience a broken bone at some point. Those injuries can lead to major setbacks in function and independence from which some patients never fully recover. Fortunately, maintaining bone density can prevent such injuries. One way to maintain bone health is by getting adequate levels of calcium and vitamin D. That’s why many people want to track nutrient levels and bone density before they wind up in a hospital. But the process...

TESS discovers a planet the size of...
Ultra-short-period planets are small, compact worlds that whip around their stars at close range, completing an orbit — and a single, scorching year — in less than 24 hours. How these planets came to be in such extreme configurations is one of the continuing mysteries of exoplanetary science. Now, astronomers have discovered an ultra-short-period planet (USP) that is also super light. The planet is named GJ 367 b, and it orbits its star in just eight hours. The planet...

Silicon Valley beckoned, but he went home...
During his first year at MIT, Max Williamson felt lost and unsure of his long-term goals. By spring, he faced what felt like a career-altering decision: pursue a coveted summer computer science research position at MIT or return home to Delaware and intern for his senator. His friends thought he was crazy to pursue public service over a high-paying career in Silicon Valley. However, after working hands-on with local communities in Delaware while also learning the tangible, human impact...

Scientists and musicians tackle climate change together
Audiences may travel long distances to see their favorite musical acts in concert or to attend large music festivals, which can add to their personal carbon footprint of emissions that are steadily warming the planet. But these same audiences, and the performers they follow, are often quite aware of the dangers of climate change and eager to contribute to ways of curbing those emissions. How should the industry reconcile these two perspectives, and how should it harness the enormous...

MIT ID cards go digital
MIT community members have a new and easier way to navigate campus life at the Institute: the MIT Mobile ID, a digital version of the MIT ID card for iOS and Android devices. Developed prior to the pandemic and released by Information Systems and Technology (IS&T), the MIT Mobile ID can be used just like a physical ID. A simple wave of your device — an iPhone, Apple Watch, or Android phone — near a reader is all it...
