Wall Street Journal reporter Lauren Weber spotlights a paper by Prof. David Autor that finds import tariffs have had little effect on job creation and preservation in the U.S., particularly in parts of the country with tariff-protected industries. Autor and his colleagues found “manufacturing employment didn’t increase, though it also didn't fall (other research found that U.S. companies had a hard time selling more products abroad, which may help explain why manufacturers didn't add jobs),” Weber explains. “Worse than that, retaliatory tariffs from trading partners led to job losses, especially in agriculture.”

MIT engineers have developed a new system that helps pesticides adhere more effectively to plant leaves, allowing farmers to use fewer chemicals without sacrificing crop protection, reports Michigan Farm News. The new technology “adds a thin coating around droplets as they are being sprayed onto a field, increasing the stickiness of pesticides by as much as a hundredfold.”

Scientific American reporter Nic Flemming spotlights research by Prof. Ömer Yilmaz and his team, which explores the impact of fasting on intestinal stem cells. “Both caloric restriction and fasting improved intestinal stem-cell activity and health, but the mechanisms involved are very different,” says Yilmaz. 

Using his background in physics, Aaron Leanhardt PhD '03 redesigned the modern baseball bat to “improve the frequency and quality of contact, based on where the batters most frequently hit the ball,” reports Alex Speier for The Boston Globe. 

USA Today reporter Steve Gardner spotlights the “torpedo bat” – a baseball bat developed by Aaron Leanhardt PhD '03. The new design moves “more of the wood toward the sweet spot of the bat, where players try to make contact and where the bat will produce optimal results,” explains Gardner. 

Prof. David Pritchard speaks with NBC News reporter David K. Li about his former student Aaron Leanhardt PhD '03 and his work developing the “torpedo” baseball bat. “It just takes some outsiders, like Aaron, who has a Ph.D. from MIT and really understands physics and knows what's going on, to be the sort of guy who drives something under the radar and see if it works," says Pritchard. 

Aaron Leanhardt PhD '03 has designed a new baseball bat, dubbed the torpedo bat, in which wood is moved “lower down the barrel after the label, and shapes the end a little like a bowling pin,” reports the Associated Press. “At the end of the day it’s about the batter not the bat,” says Leanhardt. “It’s about the hitter and their hitting coaches. I’m happy to always help those guys get a little bit better but ultimately it’s up to them to put good swings and grind it out every day. So, credit to those guys.”

Prof. Pulkit Agrawal speaks with NPR Short Wave host Regina Barber and science correspondent Geoff Brumfiel about his work developing a new technique that allows robots to train in simulations of scanned home environments. “The power of simulation is that we can collect very large amounts of data,” explains Agrawal. “For example, in three hours' worth of simulation, we can collect 100 days' worth of data.” 

Aaron Leanhardt PhD '03 has developed a new baseball bat that has “moved the fattest part from the end to the area where most contact is made,” reports Steve Henson for The Los Angeles Times.

Aaron Leanhardt PhD '03 speaks with The Athletic reporter Brendan Kuty about his work developing a new “torpedo-like” baseball bat. The bats “are custom-made to player preferences and are designed so that the densest part of the bat is where that particular hitter most often makes contact with the baseball,” writes Kuty. Says Leanhardt of the bat’s design: “It’s just about making the bat as heavy and as fat as possible in the area where you’re trying to do damage on the baseball.” 

MIT researchers have observed “Hofstadter’s butterfly” – the quantum theory that proposes “under the right conditions, tiny electrons in a quantum system could produce an energy spectrum composed of fractals” that would resemble a butterfly, reports Gayoung Lee for Scientific American. The discovery, “emerged from the complex quantum dance of electrons sandwiched between two microscopic layers of graphene,” explains Lee. The results “were unexpected [as] the researchers involved weren’t even trying to hatch Hofstadter’s butterfly from its quantum chrysalis.” 

Boston Magazine reporter Wyndham Lewis spotlights the MIT AgeLab, where researchers are focused on making aging better by studying age-related issues so “products can be modified accordingly for older people, allowing them to do the things they’ve always done." AgeLab Director Joseph Coughlin explains: “MIT is about envisioning and inventing the future. I want the AgeLab to write a new narrative of a 100-year life.” He adds that it’s about “setting the agenda for what 100 good years could be.”

Rachel Feltman of Scientific American’s “Science Quickly” podcast visits MIT.nano to learn more about MIT’s “clean laboratory facility that is critical to nanoscale research, from microelectronics to medical nanotechnology.” Prof. Vladimir Bulović, director of MIT.nano, explains: “Maybe a fifth of all of M.I.T.’s research depends on this facility…from microelectronics to nanotechnology for medicine to different ways of rethinking what will [the] next quantum computation look like. Any of these are really important elements of what we need to discover, but we need all of them to be explored at the nanoscale to get that ultimate performance.” 

Prof. David Sontag, Monica Agrawal PhD '23, Luke Murray SM '22, and Divya Gopinath '19, MEng '20 co-founded Layer Health - an AI healthcare startup that is applying large language models (LLMs) to help clinicians with medical chart reviews and data abstraction, reports Seth Joseph for Forbes. “The same chart review problem we’re solving with our clinical registry module is faced by clinicians at the point of care,” says Sontag. “For example, one of our next modules will focus on real-time clinical decision support to help automate clinical care pathways, leading to more reliable, high-quality care."
