A new study co-authored by Prof. S.P. Kothari “analyzes the stock returns of thousands of companies from 1988-2020, comparing those that repurchased shares against firms that didn’t, adjusting for their size and other factors,” reports Jason Zweig for The Wall Street Journal. “We don’t see massive misuse as some people allege,” says Kothari. “This isn’t a rigged game where CEOs are lining their pockets.”
Researchers at MIT and elsewhere are analyzing patients’ speech patterns to see if they can detect Lou Gehrig’s disease in its early stages, reports Ben Leonard, Ruth Reader, Carmen Paun and Erin Schumaker for Politico. “Catching it early and beginning treatment can improve patients’ quality of life and delay symptom onset,” they write.
Prof. Feng Zhang founded Aera Therapeutics, a startup working to deliver curative genetic medicine to hard-to-reach parts of the body, reports Ryan Cross for The Boston Globe. “If Aera’s approach works in people, it could broaden the reach of genetic therapies, which currently have limited clinical applications – partly because there aren’t enough methods for getting those medicines to hone in on the right cells,” writes Cross.
An ingestible, pill-shaped sensor module, which can pinpoint its location as it moves through the body, has been developed by researchers at MIT and Caltech, reports Andrew Paul for Popular Science. This method “could one day offer an effective means to assess issues like constipation, gastroesophageal reflux disease, and gastroparesis,” writes Paul.
Researchers at MIT have developed a drone that can be controlled using hand gestures, reports Mashable. “I think it’s important to think carefully about how machine learning and robotics can help people to have a higher quality of life and be more productive,” says postdoc Joseph DelPreto. “So we want to combine what robots do well and what people do well so that they can be more effective teams.”
MIT scientists have developed a new way of colliding ultracold molecules while controlling the rate at which they react, reports Martijn Boerkamp for Physics World. “Our work is a step to achieve quantum control over molecular collisions and reactions and to map out more broadly the collisional properties of these molecules with the goal of finding a deeper understanding,” explains Prof. Wolfgang Ketterle.
Researchers from MIT and Caltech have developed a pill-shaped ingestible sensor that can be monitored as it moves through the GI tract, allowing doctors to more easily diagnose gastrointestinal disorders, reports Brian Heater for TechCrunch. “The ability to characterize motility without the need for radiation, or more invasive placement of devices, I think will lower the barrier for people to be evaluated,” says Prof. Giovanni Traverso.
A study co-authored by Senior Lecturer Donald Sull found that the top factor in employee retention is corporate environment, reports Ellen Rosen for The New York Times. Sull says that a toxic work culture was “10 times more predictive of having a higher-than-industry-average attrition rate than compensation.”
Motherboard reporter Tatyana Woodall writes that a new study co-authored by MIT researchers finds that AI models that can learn to perform new tasks from just a few examples create smaller models inside themselves to achieve these new tasks. “Learning is entangled with [existing] knowledge,” graduate student Ekin Akyürek explains. “We show that it is possible for these models to learn from examples on the fly without any parameter update we apply to the model.”
Researchers from the MIT Center for Real Estate Research and elsewhere have found that high carbon dioxide levels can contribute to students achieving lower scores on standardized tests, reports Brandon Kochkodin for Forbes. “Poor air quality is a widespread issue that seems to affect the bulk of the student population,” says Prof. Juan Palacios.
Postdoctoral Fellow Lydia Harrington and Boston University Postdoctoral Associate Chloe Bordewich speak with WBUR reporter Yasmin Amer about their exhibit at the MIT Rotch Library on Boston's former Little Syria neighborhood. “We want to show very positive things that Syrians brought with them, as well as their contributions to Boston,” says Harrington. “We wanted to show things in the exhibit that showed everyday life and well-known people in the neighborhood.”
Researchers at MIT and Massachusetts General Hospital have developed “Sybil” – an artificial intelligence tool that can predict the risk of a patient developing lung cancer within six years, reports Mallika Marshall for CBS Boston.
Prof. Sara Seager and her colleagues write for Physics Today about how the SpaceX Starship could help transform astrophysics missions. “Assuming it is successful, Starship will dramatically enhance our space capabilities in ways that will qualitatively alter how astrophysics missions can be built,” write Seager and her colleagues.
Researchers at MIT have developed underwater robotic structures that can contort into different shapes, reports Andrew Paul for Popular Science. “This ability is key in submersible robots, since it allows them to move through the water much more efficiently, as countless varieties of fish do in rivers, lakes, and the open ocean,” explains Paul.
Writing for the Financial Times, Prof. Daron Acemoglu and his co-authors explore their research demonstrating that “the biggest shift when a chief executive with a business degree takes charge is a decline in wages and the share of revenues going to labor.” Acemoglu and his co-authors note that while many business schools have updated their offerings to include more ethics courses, they emphasize the importance of “being aware of what managers with business degrees used to do is an important step in reflecting on how we can build better programs.”
