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...

Summer research offers a springboard to advanced...

August 16, 2023

Doctoral studies at MIT aren’t a calling for everyone, but they can be for anyone who has had opportunities to discover that science and technology research is their passion and to build the experience and skills to succeed. For Taylor Baum, Josefina Correa Menéndez, and Karla Alejandra Montejo, three graduate students in just one lab of The Picower Institute for Learning and Memory, a pivotal opportunity came via the MIT Summer Research Program in Biology and Neuroscience (MSRP-Bio). When...

Simple superconducting device could dramatically cut energy...

August 15, 2023

MIT scientists and their colleagues have created a simple superconducting device that could transfer current through electronic devices much more efficiently than is possible today. As a result, the new diode, a kind of switch, could dramatically cut the amount of energy used in high-power computing systems, a major problem that is estimated to become much worse. Even though it is in the early stages of development, the diode is more than twice as efficient as similar ones reported...

A snapshot of cancer vaccine development

August 15, 2023

The road to effective cancer vaccines has been long and difficult. Although initial attempts to use a vaccine to treat cancer date back to the 1910s, the first effective therapeutic vaccine would not emerge until about a century later, when Sipuleucel-T was used to treat prostate cancer in 2010. While the FDA-approved prostate cancer vaccine generated much excitement, its success has proven difficult to replicate. T-VEC, used to treat metastatic melanoma, is the only other cancer therapeutic vaccine approved...

AI models are powerful, but are they...

August 15, 2023

Artificial neural networks, ubiquitous machine-learning models that can be trained to complete many tasks, are so called because their architecture is inspired by the way biological neurons process information in the human brain. About six years ago, scientists discovered a new type of more powerful neural network model known as a transformer. These models can achieve unprecedented performance, such as by generating text from prompts with near-human-like accuracy. A transformer underlies AI systems such as ChatGPT and Bard, for...

When rumors take flight

August 15, 2023

Misinformation pervades U.S. politics. The outcome of the 2020 presidential election is perhaps the most pressing case in point. Every serious-minded academic and legal inquiry into the subject — including two cases that came before the U.S. Supreme Court — has rejected former President Donald Trump’s assertion that he did not lose the election. Major media organizations now routinely label these statements “lies.” Yet Trump’s unfounded claims have gained wide traction among his followers. “The evidence against claims that...

Invisible tagging system enhances 3D object tracking

August 15, 2023

Stop me if you’ve seen this before: a black and white pixelated square in lieu of a physical menu at a restaurant. QR codes are seemingly ubiquitous in everyday life. Whether you see one on a coupon at the grocery store, a flyer on a bulletin board, or the wall at a museum exhibit, each code contains embedded data. Unfortunately, QR codes in physical spaces are sometimes replaced or tampered with to trick you into giving away your data...

Professor Emeritus Sanjoy Mitter, expert in the...

August 11, 2023

MIT Professor Emeritus (post-tenure) Sanjoy Mitter, a member of the MIT Department of Electrical Engineering and Computer Science, died June 26 at age 89. An expert in the theoretical foundations of systems, communication and control, Mitter contributed to significant engineering applications, most notably in the control of interconnected power systems and pattern recognition. Sanjoy Mitter was born in 1933 in Calcutta, India, to a prominent family with a distinguished line of jurists. His paternal grandfather, Sir Binod Mitter, was...

Communicating across time

August 11, 2023

Since the invention of the telegraph, humans have been able to communicate across great distances in real-time. Today, we can choose among myriad technologies — radio, telephone, video conference platforms — to connect with colleagues and loved ones in different time zones, countries, and continents. These technologies create a telepresence — a sense of nearness between living beings separated only by space. “The purpose of telepresence is to connect people who are alive,” says Hiroshi Ishii, the Jerome B....

A welcome new pipeline for students invested...

August 11, 2023

Akarsh Aurora aspired “to be around people who are actually making the global energy transition happen,” he says. Sam Packman sought to “align his theoretical and computational interests to a clean energy project” with tangible impacts. Lauryn Kortman says she “really liked the idea of an in-depth research experience focused on an amazing energy source.” These three MIT students found what they wanted in the Fusion Undergraduate Scholars (FUSars) program launched by the MIT Plasma Science and Fusion Center...

3 Questions: Boosting concrete’s ability to serve...

August 10, 2023

Damian Stefaniuk is a postdoc at the MIT Concrete Sustainability Hub (CSHub). He works with MIT professors Franz-Josef Ulm and Admir Masic of the MIT Department of Civil and Environmental Engineering (CEE) to investigate multifunctional concrete. Here, he provides an overview of carbonation in cement-based products, a brief explanation of why understanding carbonation in the life cycle of cement products is key for assessing their environmental impact, and an update on current research to bolster the process. Q: What...

August 10, 2023

Thomas G. Coveney, a dedicated systems administrator at the MIT Center for Transportation and Logistics (CTL), died on July 14 after a lengthy battle with cancer. He was 55 years old. “Tom was an exceptional systems administrator whose dedication and loyalty to CTL were unparalleled. His loss is a profound one, and we will miss him greatly,” says Yossi Sheffi, director of CTL and the Elisha Gray II Professor of Engineering Systems. Coveney joined MIT in 2000 as a...

MIT Press’s Direct to Open (D2O) opens...

August 9, 2023

Thanks to the support of libraries participating in Direct to Open (D2O), the MIT Press will publish its full list of 2023 scholarly monographs and edited collections open access. Launched in 2021, D2O from the MIT Press is a sustainable framework that harnesses the collective power of libraries to support open and equitable access to vital, leading scholarship. D2O moves scholarly books from a solely market-based, purchase model, where individuals and libraries buy single e-books, to a collaborative open-access model,...
