Working to make nuclear energy more competitive

March 8, 2023

Assil Halimi has loved science since he was a child, but it was a singular experience at a college internship that stoked his interest in nuclear engineering. As part of work on a conceptual design for an aircraft electric propulsion system, Halimi had to read a chart that compared the energy density of various fuel sources. He was floored to see that the value for uranium was orders of magnitude higher than the rest. “Just a fuel pellet the...

eDNA holds the key to safeguarding pollinators...

March 8, 2023

Researchers have uncovered new evidence of western pygmy possums interacting with native flowers, providing an eDNA study to simultaneously detect mammal, insect and bird DNA on flowers.

Study: Smoke particles from wildfires can erode...

March 8, 2023

A wildfire can pump smoke up into the stratosphere, where the particles drift for over a year. A new MIT study has found that while suspended there, these particles can trigger chemical reactions that erode the protective ozone layer shielding the Earth from the sun’s damaging ultraviolet radiation. The study, which appears today in Nature, focuses on the smoke from the “Black Summer” megafire in eastern Australia, which burned from December 2019 into January 2020. The fires — the...

MIT Cheney Room reopens with fresh and...

March 7, 2023

The Margaret Cheney Room celebrated its reopening last month after significant updates and remodeling over the last several months. The celebration was led by Lauryn McNair, assistant dean of LBGTQ+ Women and Gender Services, and attended by MIT Chancellor Melissa Nobles, Provost Cynthia Barnhart, and numerous students, staff, and alumni. In 1884, MIT founded the Margaret Cheney Reading Room as a space for women on campus to gather. The room was named after Margaret Swan Cheney, a member of...

Nanotube sensors are capable of detecting and...

March 7, 2023

Researchers from the Disruptive and Sustainable Technologies for Agricultural Precision (DiSTAP) interdisciplinary research group of the Singapore-MIT Alliance for Research and Technology (SMART), MIT’s research enterprise in Singapore, and their collaborators from Temasek Life Sciences Laboratory have developed the first-ever nanosensor that can detect and distinguish gibberellins (GAs), a class of hormones in plants that are important for growth. The novel nanosensors are nondestructive, unlike conventional collection methods, and have been successfully tested in living plants. Applied in the...

3 Questions: Antje Danielson on energy education...

March 6, 2023

The MIT Energy Initiative (MITEI) leads energy education at MIT, developing and implementing a robust educational toolkit for MIT graduate and undergraduate students, online learners around the world, and high school students who want to contribute to the energy transition. As MITEI’s director of education, Antje Danielson manages a team devoted to training the next generation of energy innovators, entrepreneurs, and policymakers. Here, she discusses new initiatives in MITEI’s education program and how they are preparing students to take...

Learning to compute through art

March 6, 2023

One student confesses that motors have always freaked them out. Amy Huynh, a first-year student in the MIT Technology and Policy Program, says “I just didn’t respond to the way electrical engineering and coding is usually taught.” Huynh and her fellow students found a different way to master coding and circuits during the Independent Activities Period course Introduction to Physical Computing for Artists — a class created by Student Art Association (SAA) instructor Timothy Lee and offered for the...

Daniel Hastings named American Institute of Aeronautics...

March 6, 2023

The American Institute of Aeronautics and Astronautics (AIAA) announced Wednesday that MIT professor Daniel Hastings has been elected president-elect of the organization. Hastings, the associate dean of engineering for diversity, equity, and inclusion; head of the Department of Aeronautics and Astronautics; and the Cecil and Ida Green Education Professor of Aeronautics and Astronautics, will be AIAA’s the 17th president with ties to MIT and the first Black president. Hastings will assume the presidency in May 2024, succeeding current president...

Assessing Russia’s invasion of Ukraine, after a...

March 6, 2023

Ukraine has been withstanding Russia’s invasion for slightly more than a year. One element of this resistance has been the military aid many allies have provided Ukraine. But surely the most important factor, ever since Russia attacked in February 2022, has been the strong sense of solidarity Ukranians have displayed in their attempt to keep their country free and democratic. That was one takeaway from a recent public discussion at MIT, “Ukraine and Russia One Year On: The Domestic...

On social media platforms, more sharing means...

March 3, 2023

As a social media user, you can be eager to share content. You can also try to judge whether it is true or not. But for many people it is difficult to prioritize both these things at once. That’s the conclusion of a new experiment led by MIT scholars, which finds that even considering whether or not to share news items on social media reduces people’s ability to tell truths from falsehoods. The study involved asking people to assess...

QuARC 2023 explores the leading edge in...

March 3, 2023

The second QSEC Annual Research Conference (QuARC) brought together MIT student and postdoctoral researchers, staff, faculty, and industry partners for a two-day exploration of the leading edge in quantum information science and engineering. Held on Jan. 23 and 24 at the Omni Mount Washington Resort in New Hampshire, QuARC featured keynote addresses from prominent thinkers in the field, as well as presentations and posters on the latest results from MIT research. The conference launched in 2022 to give members...

MIT Press announces inaugural recipients of the...

March 3, 2023

The MIT Press has announced the first recipients of the Grant Program for Diverse Voices. Launched in 2021 to expand funding for authors whose experience and knowledge of diverse communities informs books that meet the highest standards of peer-reviewed scholarship, the initiative provides support for the research and writing of new works. “The MIT Press has a proud legacy of bold, socially engaged publishing that champions the sharing of information and ideas from diverse perspectives,” says Amy Brand, director...

Aviva Intveld named 2023 Gates Cambridge Scholar

March 3, 2023

MIT senior Aviva Intveld has won the prestigious Gates Cambridge Scholarship, which offers students an opportunity to pursue graduate study in the field of their choice at Cambridge University in the U.K. Intveld will join the other 23 U.S. citizens selected for the 2023 class of scholars. Intveld, from Los Angeles, is majoring in earth, atmospheric, and planetary sciences, and minoring in materials science and engineering with concentrations in geology, geochemistry, and archaeology. Her research interests span the intersections...

Remembering Professor Emeritus Edgar Schein, an influential...

March 3, 2023

Edgar H. Schein, a social psychologist who bridged the academic and pragmatic sides of culture and organization by practicing his own tenets on humble leadership and inquiry, died Jan. 26. He was 94. Schein, who was the Society of Sloan Fellows professor of management emeritus at MIT Sloan, joined the school in 1956, when it was still known as the MIT School of Industrial Management. During his 67-year tenure, Schein authored dozens of books on social science subjects including...

Large language models are biased. Can logic...

March 3, 2023

Turns out, even language models “think” they’re biased. When prompted in ChatGPT, the response was as follows: “Yes, language models can have biases, because the training data reflects the biases present in society from which that data was collected. For example, gender and racial biases are prevalent in many real-world datasets, and if a language model is trained on that, it can perpetuate and amplify these biases in its predictions.” A well-known but dangerous problem. Humans (typically) can dabble...
