Everything is a Brand

Speaking hypothetically

August 23, 2023

What’s the winning number for next week’s Mega Millions? If Julie knew the number, Leah would know the number. But you know that neither person holds this precious secret — and not just because Mega Millions hasn’t been drawn yet. You know because you understand the implication of the sentence, even though it is free of any “not,” “no,” or other form of negation. How you understand sentences like this — how you make what linguists call a “counterfactual inference”...

Cracking the code that relates brain and...

August 23, 2023

To understand the full relationship between brain activity and behavior, scientists have needed a way to map this relationship for all of the neurons across a whole brain — a so far insurmountable challenge. But after inventing new technologies and methods for the purpose, a team of scientists in The Picower Institute for Learning and Memory at MIT has produced a rigorous accounting of the neurons in the tractably tiny brain of a humble C. elegans worm, mapping out how its...

Planning algorithm enables high-performance flight

August 23, 2023

A tailsitter is a fixed-wing aircraft that takes off and lands vertically (it sits on its tail on the landing pad), and then tilts horizontally for forward flight. Faster and more efficient than quadcopter drones, these versatile aircraft can fly over a large area like an airplane but also hover like a helicopter, making them well-suited for tasks like search-and-rescue or parcel delivery. MIT researchers have developed new algorithms for trajectory planning and control of a tailsitter that take...

Making aviation fuel from biomass

August 23, 2023

In 2021, nearly a quarter of the world’s carbon dioxide emissions came from the transportation sector, with aviation being a significant contributor. While the growing use of electric vehicles is helping to clean up ground transportation, today’s batteries can’t compete with fossil fuel-derived liquid hydrocarbons in terms of energy delivered per pound of weight — a major concern when it comes to flying. Meanwhile, based on projected growth in travel demand, consumption of jet fuel is projected to double...

Chris Schuh named dean of Northwestern University...

August 22, 2023

A first-year graduate student in MIT’s Department of Materials Science and Engineering (DMSE) in 2007, Tim Rupert was prepared to present research at a Materials Research Society conference in Boston, his first presentation since joining the lab of Professor Chris Schuh. “The slides were all ready, the story was all ready — I practiced it, and I was ready to go,” says Rupert, now a professor of materials science and engineering at the University of California at Irvine. “And...

Machine-learning system based on light could yield...

August 22, 2023

ChatGPT has made headlines around the world with its ability to write essays, email, and computer code based on a few prompts from a user. Now an MIT-led team reports a system that could lead to machine-learning programs several orders of magnitude more powerful than the one behind ChatGPT. The system they developed could also use several orders of magnitude less energy than the state-of-the-art supercomputers behind the machine-learning models of today. In the July 17 issue of Nature...

Q&A: Steven Gonzalez on Indigenous futurist science...

August 21, 2023

Steven Gonzalez is a PhD candidate in the MIT Doctoral Program in History, Anthropology, Science, Technology, and Society (HASTS), where he researches the environmental impacts of cloud computing and data centers in the United States, Iceland, and Puerto Rico. He is also an author. Writing under the name E.G. Condé, he recently published his first book, “Sordidez.” It’s described as an “Indigenous futurist science fiction novella set in Puerto Rico and the Yucatán.” Set in the near future, it follows...

M'Care and MIT students join forces to...

August 21, 2023

Through a collaboration between M’Care, a 2021 Health Security and Pandemics Solver team, and students from MIT, the landscape of child health care in Nigeria could undergo a transformative change, wherein the power of data is harnessed to improve child health outcomes in economically disadvantaged communities. M’Care is a mobile application of Promane and Promade Limited, developed by Opeoluwa Ashimi, which gives community health workers in Nigeria real-time diagnostic and treatment support. The application also creates a dashboard that...

MIT at the 2023 Venice Biennale

August 18, 2023

The Venice Architecture Biennale, the world’s largest and most visited exhibition focusing on architecture, is once again featuring work by many MIT faculty, students, and alumni. On view through Nov. 26, the 2023 biennale, curated by Ghanaian-Scottish architect, academic, and novelist Lesley Lokko, is showcasing projects responding to the theme of “The Laboratory of Change.” Architecture and Planning and curator of the previous Venice Biennale. “Our students, faculty, and alumni have responded to the speculative theme with innovative projects...

Artificial intelligence for augmentation and productivity

August 18, 2023

The MIT Stephen A. Schwarzman College of Computing has awarded seed grants to seven projects that are exploring how artificial intelligence and human-computer interaction can be leveraged to enhance modern work spaces to achieve better management and higher productivity. Funded by Andrew W. Houston ’05 and Dropbox Inc., the projects are intended to be interdisciplinary and bring together researchers from computing, social sciences, and management. The seed grants can enable the project teams to conduct research that leads to...

To improve solar and other clean energy...

August 17, 2023

To continue reducing the costs of solar energy and other clean energy technologies, scientists and engineers will likely need to focus, at least in part, on improving technology features that are not based on hardware, according to MIT researchers. They describe this finding and the mechanisms behind it today in Nature Energy. While the cost of installing a solar energy system has dropped by more than 99 percent since 1980, this new analysis shows that “soft technology” features, such...

MIT researchers combine deep learning and physics...

August 17, 2023

Compared to other imaging modalities like X-rays or CT scans, MRI scans provide high-quality soft tissue contrast. Unfortunately, MRI is highly sensitive to motion, with even the smallest of movements resulting in image artifacts. These artifacts put patients at risk of misdiagnoses or inappropriate treatment when critical details are obscured from the physician. But researchers at MIT may have developed a deep learning model capable of motion correction in brain MRI. “Motion is a common problem in MRI,” explains...

How machine learning models can amplify inequities...

August 17, 2023

Prior to receiving a PhD in computer science from MIT in 2017, Marzyeh Ghassemi had already begun to wonder whether the use of AI techniques might enhance the biases that already existed in health care. She was one of the early researchers to take up this issue, and she’s been exploring it ever since. In a new paper, Ghassemi, now an assistant professor in MIT’s Department of Electrical Science and Engineering (EECS), and three collaborators based at the Computer...

The tenured engineers of 2023

August 17, 2023

In 2023, MIT granted tenure to nine faculty members across the School of Engineering. This year’s tenured engineers hold appointments in the departments of Biological Engineering, Civil and Environmental Engineering, Electrical Engineering and Computer Science (which reports jointly to the School of Engineering and MIT Schwarzman College of Computing), Materials Science and Engineering, and Mechanical Engineering, as well as the Institute for Medical Engineering and Science (IMES). “I am truly inspired by this remarkable group of talented faculty members,”...

MIT Code for Good Club works with...

August 16, 2023

Computer hackers who break into websites, change the code, and do harm are very real. But MIT Code for Good members want to do just the opposite. This group of mostly electrical engineering and computer science majors (EECS, Course 6) wants to help important causes. Each semester, club members consult with nonprofits in the Boston area to support their technical needs. Formed in 2016, the club currently has 20 undergraduate members, but graduate students are also welcome. The work...
