Writing for The New York Times, Prof. Daron Acemoglu and University of Chicago Prof. James A. Robinson propose solutions to address growing distrust in democracy. “We need a new democratic social contract that people can believe in,” they write. “Democracy does not need to follow a majoritarian opinion on every topic, but it cannot sideline the views of the majority of the population, even on divisive subjects such as immigration.”

Prof. Li-Huei Tsai, director of the Picower Institute, speaks with NPR host Jon Hamilton about her work identifying a protein called reelin that appears to protect brain cells from Alzheimer's. “Tsai says she and her team are now using artificial intelligence to help find a drug that can replicate what reelin does naturally,” says Hamilton. 

Researchers at MIT have developed a new method for “training home robots in simulation,” reports Brain Heater for TechCrunch. “Simulation has become a bedrock element of robot training in recent decades,” explains Heater. “It allows robots to try and fail at tasks thousands — or even millions — of times in the same amount of time it would take to do it once in the real world.” 

Research affiliate Thomas Neff, a physicist known for his proposal aimed at “reducing the global stockpile of nuclear weapons and helping stabilize the former Soviet Union,” has died at age 80, reports Harrison Smith for the Washington Post. Credited with the “Megatons to Megawatts” agreement, “Dr. Neff spent years working in arms control, nuclear weapons proliferation and uranium markets, bridging the divide between experts who specialized in the kind of highly enriched uranium used for warheads and the far less enriched version used for electricity generation,” Smith writes.

Researchers from the Data Provenance Initiative, a research group led by MIT engineers, have found that “important web sources used for training AI models have restricted the use of their data,” reports Kevin Roose for The New York Times. . “We’re seeing a rapid decline in consent to use data across the web that will have ramifications not just for A.I. companies, but for researchers, academics and noncommercial entities,” explains graduate student Shayne Longpre.

Graduate student Lt. Col. Jill Rahon, a war veteran and seasoned pilot, discusses her journey from her tours in Afghanistan to her research at MIT on engineering solutions for the enforcement of nuclear nonproliferation accords, writes Sam Cavanaugh for Hoodline. “The path Rahon has blazed is marked by courage and ingenuity, from deftly handling the controls of a Chinook helicopter over the treacherous terrains of Afghanistan to meticulously studying the nuances of resonance analysis to keep nuclear powers in check,” writes Cavanaugh. 

Prof. Richard Binzel organized a centennial celebration for the Johnstown meteorite – a meteorite that was seen crashing into Earth on July 6, 1924 in Weld County, Colorado, and later “became a link to understanding a whole class of meteorites,” reports Elizabeth Gamillo for Astronomy. “Binzel describes the Johnstown rock not as the meteorite that launched a thousand ships, but one that instead launched one major mission to the asteroid belt,” writes Gamillo. 

Joesph Coughlin, director of the AgeLab, speaks with Atlantic reporter Charley Locke about how retirement can result in feelings of identity loss and can present cognitive and emotional health challenges. “When people are at the center of their universe through their job, we don’t have a storyline or a place in our society that is attractive enough to say, ‘Maybe I’ve had enough,’” says Coughlin. “You’re showing people the door with no direction.” 

MIT researchers have found that a textured surface, designed like a shark riblet, can improve the towed sonar arrays (TSAs) that are "vital for marine vessels engaged in underwater security or exploration projects," reports Andrew Paul for Popular Science. “Utilizing computational modeling, researchers tested various riblet shapes and patterns interacting with simulated water environments,” explains Paul. “From calm currents to the more commonly unpredictable flows seen in oceans, the team observed how smooth, triangular, trapezoidal, and scalloped riblets might affect fluid dynamics and acoustics.”

Melissa Choi, who has served as assistant director of MIT Lincoln Laboratory since 2019 and has decades of experience working across the lab’s different technical areas, has been named the next director of Lincoln Laboratory, reports Isabel Tehan for the Boston Business Journal. “Under Choi’s leadership, the lab will continue to focus on long-term development of defense systems,” writes Tehan, “as well as quick-moving prototyping, both with the goal of protecting the U.S. from advanced threats.” 

Christian Science Monitor reporter Ira Porter spotlights undergraduate Subin Kim and his experience transferring from community college to MIT through the Transfer Scholars Network, which is aimed at helping community college students find a path to four-year universities. “Every student that we admit, we’re looking for academic excellence and personal excellence,” says Stuart Schmill, dean of MIT admissions and student financial services. “And the students that we’ve brought in from the Transfer Scholar Network and in general from community colleges are remarkable individuals.”

National Defense Magazine reporter Sean Carberry spotlights Mesodyne, an MIT startup that is developing a thermal photovoltaic power generator that could be used to help extend battery power during military missions. Mesodyne’s LightCell generator can deliver “high-efficiency direct current power from a quiet device with no moving parts that could change the equation of an operator carrying 100 pounds of batteries for a three-day mission,” Carberry explains.
