A new study co-authored by Prof. David Rand found that there was a “20 percent reduction in belief in conspiracy theories after participants interacted with a powerful, flexible, personalized GPT-4 Turbo conversation partner,” writes Annie Duke for The Washington Post. “Participants demonstrated increased intentions to ignore or unfollow social media accounts promoting the conspiracies, and significantly increased willingness to ignore or argue against other believers in the conspiracy,” writes Duke. “And the results appear to be durable, holding up in evaluations 10 days and two months later.”

Prof. Richard Binzel discusses how the risk posed by asteroid 2024 YR4 has now been significantly reduced based off new information gathered on the asteroid’s trajectory, reports Ashley Strickland for CNN. The rapid de-escalation in risk is thanks to the “unsung, meticulous work by astronomers” who conducted a steady stream of follow-up observations of the space rock using telescopes across the globe,” Binzel explains. “I’m pleasantly surprised that we could reduce the probability numbers so quickly.” 

Prof. Richard Binzel speaks with Bloomberg reporter F.D. Flam about tracking asteroid 2024 YR4. “It might seem like things are getting more dangerous or more scary, but what's really happening is we're making ourselves more and more secure,” says Binzel. 

Prof. Richard Binzel speaks with NBC News reporter Denise Chow about the Torino scale, a method he developed for categorizing the risks posed by near-Earth objects. “The idea was to be as transparent as possible about what astronomers know,” says Binzel of the idea behind the scale.

Prof. Richard Binzel speaks with Forbes reporter Jamie Carter about how astronomers are working to determine the trajectory of asteroid 2024 YR4. “Eventually, we expect the probability to fall to zero and reach Torino Scale 0 (all clear!),” says Binzel. “The uncertainty region, which looks like a long spaghetti of fettuccine string, shrinks as we get tracking data over a longer and longer piece of the asteroid’s orbit.”

Prof. Richard Binzel, creator of the Torino scale that NASA uses to measure the threat of incoming objects, speaks with Brandon Truitt of CBS Boston about his quest to track 2024 YR4, an asteroid that astronomers are closely monitoring to see how close it might come to Earth in 2032. “As we get more and more measurements, we keep tracking the asteroid, that uncertainty window, that broad range of where it could go it's going to shrink and shrink," says Binzel. "Until the Earth falls outside of that pathway, we're going to see these probabilities bounce around."

Tushar Shah '93, PhD '00 will join a six-member crew on Blue Origin’s upcoming New Shepard mission to space, reports Valerie Stimac for Forbes. “The mission represents another milestone in Blue Origin’s ongoing effort to expand access to commercial spaceflight,” writes Stimac. 

Varun Mohan '17, SM '17 and Douglas Chen '17 co-founded Codeium, an AI-powered coding startup designed to help users write code in a faster and more efficient manner, reports Marina Temkin for TechCrunch. “Codeium tries to distinguish itself from competitors by targeting companies rather than individual developers,” writes Temkin. 

Prof. Sarah Millholland, Prof. Christian Wolf, Prof. Emil Verner, Prof. Darcy McRose, Prof. Marzyeh Ghassemi, Prof. Mohsen Ghaffari and Prof. Ariel Furst have received the 2025 Sloan Research Fellowship for “being among the most promising scientific researchers currently working in their fields,” reports Michael T. Nietzel for Forbes. “Sloan Research Fellows are chosen in seven scientific and technical fields—chemistry, computer science, Earth system science, economics, mathematics, neuroscience, and physics,” explains Nietzel. 

Prof. Richard Binzel speaks with CNN reporter Ashley Strickland about the trajectory of asteroid 2024 YR4. “YR4 presents a challenge because it is small and headed away. Telescopes on the ground can track it for a few more months. Then we’ll call (the James Webb Space Telescope) into service to track it even further, if needed,” says Binzel. “While certainty for 2024 YR4 missing the Earth is the outcome we expect, it’s not up to us. It’s for nature to decided. In fact, nature already has settled the question. We just don’t know that answer yet. That’s why our tracking efforts continue.”

Prof. Richard Binzel, Prof. Julien de Wit, and Research Scientist Artem Burdanov speak with NBC 10 Boston reporter Matt Fortin about their new asteroid-detecting method that will be used to track the newly discovered asteroid 2024 YR4 and help protect Earth. “By refining and applying their technique, my colleagues [de Wit and Burdanov] have basically turned the JWST into the most capable asteroid-tracking system in history,” explains Binzel.

Nature reporter Elizabeth Gibney spotlights QuEra, an MIT spinout that uses atoms and lasers to encode quantum bits or “qubits.” Gibney notes that in the QuEra system, “physicists trap an array of rubidium atoms using laser light and store quantum information in the energy levels of their electrons.”

In an interview with NBC News reporter Kathy Park, Prof. Richard Binzel, Prof. Julien de Wit, and Research Scientist Artem Burdanov provide insight into astronomer's efforts to learn more about asteroid 2024 YR4. “This is an object that merits tracking by astronomers, merits our attention and that’s simply what we are doing,” says Binzel. 

Profs. Richard Binzel, Julien de Wit and Research Scientist Artem Burdanov speak with Boston Globe reporter Sarah Mesdjian about asteroid 2024 YR4 and their work developing a new method to “find and track far-away asteroids that were previously undetectable by using technology they compared to long-exposure images.” Says Binzel: “With improving technology, we are going to be aware of more and more of these objects.” He adds: “It’s a really important learning process what we’re doing right now. So when we find more and more of them, we know how to quickly process them and assess which of them are really worth looking further into.”

Prof. Jeff Gore speaks with WBUR Here & Now host Peter O’Dowd about retiring the U.S. penny. “I think that the primary cost of continuing to mint the penny is the fact that it means we feel we actually have to use it,” explains Gore. “I think that the value of our time that is wasted handling pennies is worth even more than the wasted materials.”
