The Boston Globe remembers James Santoro ’23; Karenna Groff ’22, MEng ’23; her father, Michael Groff, MD an executive MBA student at MIT’s Sloan School of Management; and three others who passed away in a plane accident earlier this week. “Both Karenna and James were tremendous contributors to their sport teams, the institution, and their local communities,” says G. Anthony Grant, MIT’s director of athletics and head of the Department of Athletics, Physical Education, and Recreation, adding: “We offer our sincere condolences and grieve with the Groff and Santoro families as well as their loved ones.” E. Antonio Chiocca, a friend of the Groff family, remembers Dr.Groff as, “Just a really nice guy, great family man. Just an amazing individual.”

Researchers at MIT have concluded that AI does not develop “value systems” over time, reports Kyle Wiggers for TechCrunch. “For me, my biggest takeaway from doing all this research is to now have an understanding of models as not really being systems that have some sort of stable, coherent set of beliefs and preferences,” says graduate student Stephen Casper. “Instead, they are imitators deep down who do all sorts of confabulation and say all sorts of frivolous things.”

Graduate students Chuck Downing and Zhichu Ren PhD '24 highlight the potential uses of AI in the research process, reports Amanda Heidt for Nature. “I didn’t know much going in, but I learnt quite a bit, and so I use these deep dives all the time now,” says Downing on using deep-research tools when approaching unfamiliar topics. “It’s better than anything else I’ve used so far at finding good papers and in presenting the information in a way that I can easily understand.”

Kodiak Brush '17 speaks with Fast Company reporter Jesus Diaz about his work tackling football helmet design. The Apache helmet Brush designed for Light Helmets is the “lightest on the market—and yet it has achieved the highest safety score ever recorded by Virginia Tech’s independent helmet testing lab.” Diaz notes that for Brush, “success isn’t measured by sales figures or accolades—it’s about changing how people think about football safety and avoiding traumatic brain injuries.”

Jon Arizti Sanz PhD '24 and postdoctoral associate Ren Hao Soon have been named to the 2025 cohort of Schmidt Science Fellows, reports Michael T. Nietzel for Forbes. “This year’s class of 32 fellows are all recent PhDs who’ve been identified as some of the most outstanding early-career scientists in the world,” explains Nietzel.

Biology graduate Katharine Dexter McCormick, SB 1904, a philanthropist, a pivotal force in the fight for women's suffrage and chief funder of the science that led to the birth control pill, is included in the New York Times’ Overlooked series, which features obituaries of “remarkable people whose deaths, beginning in 1851, went unreported in The Times.”  Rejecting societal conventions, McCormick “successfully challenged a rule that female students had to wear hats at all times, arguing that they posed a fire hazard in the science labs,” writes Katharine Q. Seelye. 

Aaron Leanhardt PhD '03 speaks with ABC News about his work developing the “torpedo bat,” a new baseball bat design that “moves the barrel – or the thickest part – closer than usual to the batter’s hand, putting more wood in the area where the hitter is most likely to hit the ball.” Leanhardt explains: “The world of data analytics, physics, math, etc., can have such a positive impact on the game of baseball and generate so much excitement.”  

Wall Street Journal reporter Jared Diamond spotlights how Aaron Leanhardt PhD ’03 went from an MIT graduate student who was part of a research team that “cooled sodium gas to the lowest temperature ever recorded in human history” to inventor of the torpedo baseball bat, “perhaps the most significant development in bat technology in decades.” Leanhardt’s new baseball bat design is aimed at helping “batters make more contact at a time when strikeouts are at an all-time high,” Diamond explains. “The result is a product that better resembles a bowling pin than a traditional bat, redistributing the weight to the area where players most often make contact with the ball.”

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.”

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.” 

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."
