Since meeting as undergraduates at MIT, graduate student Ashwin Sah '20 and Mehtaab Sawhney PhD '24 have “written a mind-boggling 57 math proofs together, many of them profound advances in various fields,” writes Leila Sloman for Quanta Magazine. Now, in what is being praised as a “huge achievement” and “phenomenally impressive” by fellow mathematicians, Sah and Sawhney have “obtained a long-sought improvement on an estimate of how big sets of integers can get before they must contain sequences of evenly spaced numbers." 

Rollerama, a pop-up roller skating rink at Kendall Common, has become a “corner of liveliness” this summer, providing the public with free fun and art in the form of a new mural by Massiel Grullon, reports Izzy Bryars for The Boston Globe. “We thought it could help people do something fun together, and start to give people a sense of what the Kendall Common build out will be like,” says Sarah Gallop, director of MIT’s Office of Government and Community Relations. 

Scientists from MIT and elsewhere are using submersible structures to harness the power of ocean waves and make sand accumulate in specific regions to protect islands and potentially grow new ones, reports Amy Gunia for CNN. “With each field experiment, the group says it is advancing its understanding of what materials, configurations, and construction techniques can make sand accumulate in the simplest, most cost-effective, sustainable, long-lasting and scalable way,” explains Gunia. 

Prof. Jeff Gore speaks with Caity Weaver of The New York Times about retiring the U.S. penny and his belief that the penny should be retired. “People think that because it exists and is used, it means that it’s useful,” Gores notes. “We’re taking something that is actually a valuable commodity, something that has actual value, and then we’re converting it into something that people just throw away.” 

Prof. Daron Acemoglu is a guest on the Financial Times podcast, “The Economics Show with Soumaya Keynes," detailing his research on the economics of AI and implications for workers. He says AI could help the current workforce communicate better and control its own data, while opening up possibilities for the geographically or economically disadvantaged, if the right policies are put in place. “I think having this conversation, and really making it a central part of the public debate that there is a technically feasible and socially beneficial different direction of technology, would have a transformative effect on the tech sector,” he explains.

Prof. Jonathan Gruber speaks with Marketplace host Daniel Ackerman about the difficulties associated with Boston’s rental market, where due to the large number of college students many housing units start their lease cycles on September 1. “You can’t fit them all in the apartment at the same time,” explains Gruber. “You can’t all get moving trucks to move in that same day.” 

Researchers at MIT have uncovered a possible reason why legal documents can be so difficult to read, finding that “convoluted legalese often acts as a way to convey authority,” reports Joe Berkowitz for Fast Company. The researchers “tested whether nonlawyers would end up using legalese if asked to write legal documents,” explains Berkowitz. “In the end, all subjects wrote their laws with complex, center-embedded clauses.”

Anurag Bajpayee MS '08, PhD '12 and Prakash Govindan PhD '12 founded Gradiant, an MIT startup “trying to reduce both costs and energy while eliminating chemicals” in water, reports Diana Olick for CNBC. “We take highly contaminated wastewater which contains solvents, which contains dissolved salt, which contains organics, and we eliminate the entire liquid waste,” says Govindan.

Prof. Nathaniel Hendren speaks with Wall Street Journal reporter Rachel Wolfe about the evolution of economic mobility in the United States. “It’s still a coin flip whether or not you’ll earn more than your parents, but mobility probably hit a record low in the early 2020s,” says Hendren. 

Associated Press reporter Bernie Wilson spotlights Christina “Chris” Birch PhD '15 and her quest to reach outer space after conquering many miles as a competitive cyclist. “Birch’s resume is staggering,” Wilson notes. “In cycling, she has 11 national championships as well as multiple Pan American and World Cup medals. She has degrees in mathematics, biochemistry and molecular biophysics, and a doctorate in biological engineering from MIT.” Of her outer space aspirations, Birch explains: “While I would love to be a scientist on the moon, doing research, collecting samples, just to be a part of our return to the moon would be incredible, because we are asking such interesting scientific questions.”
