| New Insight on Alzheimer’s | | | | | | | | A rare gene variant may contribute to Alzheimer’s by disrupting lipid metabolism and cell membranes, leading neurons into a stressed state that can damage DNA and cellular components. But the effects can be reversed through treatment with choline. | | | | Lidar helps gas industry find methane leaks and avoid costly losses Lincoln Laboratory transitioned its optical-amplifier technology to Bridger Photonics for commercialization, enhancing U.S. energy security and efficiency. |  | | | | | | | 3 Questions: On humanizing scientists The prolific MIT author and physicist Alan Lightman examines the working lives, contributions, and idealism of researchers. |  | | | | | | | Machine-learning tool gives doctors a more detailed 3D picture of fetal health MIT CSAIL researchers developed a tool that can model the shape and movements of fetuses in 3D, potentially assisting doctors in finding abnormalities and making diagnoses. |  | | | | | | | 10 years ago we first saw gravitational waves — what we’ve seen since // CBC Quirks and Quarks Professor Nergis Mavalvala, dean of the MIT School of Science, discusses how 10 years after LIGO’s first detection of gravitational waves the observatories are still “helping scientists better understand the life cycles of stars, the nature of gravity, and transforming the way we explore the farthest reaches of space.” Mavalvala shares: “Scientists have been able to design and construct these instruments that are capable of measuring imperceptibly small changes in spacetime distance, and in the past 10 years the sensitivity of these instruments has improved. That’s what is allowing us to make greater discoveries.” | | | | | | | | | | Election Day in the United States is Tuesday, Nov. 4, 2025 — make your voice heard! This National Voter Registration Day, use MIT’s TurboVote to register, request an absentee ballot or check your registration status. The Priscilla King Gray Public Service Center offers additional resources to support your civic engagement. | | | | | | Today’s date, 09/16/25, consists of three perfect squares in its month, day, and year, as well as consecutive square roots (3², 4², 5²). 2025 also marks a perfect square year, 45², and is the sum of the cubes of all single-digit numbers: 1³ + 2³ + 3³ + 4³ + 5³ + 6³ + 7³ + 8³ + 9³.
