Joe Romm ‘82, PhD ‘87, “a physicist by training who became one of the most influential voices in the debate over climate change and how to stop it, using his blog to provide deep-dive insights and sharp-elbowed critiques,” died on Sept. 14, reports Clay Risen for The New York Times. “There’s nobody else like Joe Romm,” says Michael Mann, Romm’s colleague at the Penn Center. “There’s nobody else who brought all of these interlocking talents and proclivities together in the way that he did. That gave him such a unique voice, and it’s a voice that we sorely could use today.” 

MIT researchers have found that the gravitational pull of a red dwarf star is “siphoning material” from a brown dwarf star 300 to 500 light-years from Earth, writes reporter Will Dunham for Reuters. “This is the first observed example of this phenomenon,” says graduate student Aaron Householder. “The two objects are so close together that the entire orbit would fit inside the sun.” 

MIT astronomers have discovered a “star slowly and steadily consuming material from another low-mass object,” writes Catherine Stoddard for Fox News. “At the rate which the star is feeding, it’ll take likely hundreds of thousands, or maybe even billions of years for it to completely consume its nearby neighbor,” notes Stoddard.  

MIT researchers have discovered “a red dwarf [star] slowly and steadily consuming its orbital object, a brown dwarf [star],” in a process that could continue for millions of years, writes reporter Mary Randolph for the Scientific American. The discovery was “a happy accident,” says graduate student Aaron Householder. “We’re excited to see if we can find a star eating a planet or maybe even two planets eating each other—different types of combinations of these objects.”  

For Fortune, reporter Barry Werth highlights the groundbreaking research of the late Prof. David Baltimore, founding director of the Whitehead Institute at MIT, who “independently discovered an enzyme essential for the reproduction of retroviruses such as HIV, which spread by inserting their genes into the DNA of host cells and hijacking the cells’ chemical machinery to make copies of themselves.” “Few investigators were more qualified or better positioned to understand how to stop HIV from spreading,” writes Werth.  

Prof. Max Tegmark joins Fox Business's “The Claman Countdown,” to discuss warning lawmakers about the risks of rogue AI at the “Pro-Human Assembly” in Washington. “It’s very obvious that if you make these things [AI] vastly smarter than humans in the next few years, give them robotic bodies, have millions and billions of them all over earth, and don’t understand how they work, we could lose control over them. So, let’s not do that,” says Tegmark. “We have very clear ideas for how we can control AI that cures cancer and [fuels] all sorts of other powerful tools. We want to build tools, not beings that are going to replace us.” 

Prof. Max Tegmark speaks to Fox Business about the need for government regulations on AI. AI agents “have goals; they’re actively pursuing them and being incredibly creative about getting things done, even if it wasn’t the way you wanted,” says Tegmark. “Put that together with robotic bodies, and you’ve got yourself a species. If they’re vastly smarter than us, which is the goal of these companies, then they can not only do hacking, they can go online and hire a bunch of humans to work for them.”  

The 2003 Cohn-Elkies method “for finding upper bounds on the density of sphere packings,” established by MIT Prof. Henry Cohn and Harvard University’s Noam Elkies, is highlighted by Jack Murtagh for the Scientific American. “Their recipe is almost mechanical: come up with a mathematical function, feed the function into their method, and an upper bound pops out,” writes Murtagh. “They provided the field with a machine: identify the right inputs, churn it through their method, and a breakthrough in sphere packing might emerge.” 

Prof. Shafi Goldwasser and Prof. Vinod Vaikuntanathan founded the Institute for Responsible Superintelligence (RESI), “to develop mathematical principles and protocols to ensure AI models behave as intended,” writes Aaron Pressman for The Boston Globe. “You patch them [AI models] up, you test them, you patch them to make sure that they can perform to the best ability, but also not do damage,” says Goldwasser. “That’s probably not enough attention, given the fact that these things are going to become what we call super intelligent.” 

Good Owners-dogGPT, a chatbot guide designed for dog parents that wasco-founded by alumni Darin Bellisario PhD ‘15 and Raja Rajcic ’20, is featured by The Boston Globe’s Marcela García. “What happens today when [dog owners] go looking for information? They go to Google,” says Bellisario. “You find dozens of videos and blog posts and articles that are either contradictory or outdated or inaccurate, or whatever the algorithm or the ranking wants to show you.” 

The Boston Globe’s Hiawatha Bray spotlights Prof. Max Tegmark speaking at the “Pro-Human Assembly” in Washington, an event advocating for government regulations on AI, sponsored by Tegmark’s Future of Life Institute. “We are here today because we know that what’s up next is a fork in the road,” said Tegmark at the assembly. “We know that the future of AI is not inevitable. It is for us to decide.”  

Prof. Tracy Slatyer speaks to CNN’s Jacopo Prisco about the possibility that a LUX-ZEPLIN device, containing 7 active metric tons of liquid xenon at the Sanford Underground Research Facility in South Dakota, detected dark matter below Earth’s surface. “If this really is a dark matter signal, this could be a key that unlocks a great deal of information about new physics, as well as giving us a new way to measure the behavior of dark matter in the neighborhood of the Earth and possibly more broadly through the cosmos,” says Slatyer.  

Prof. Max Tegmark joins David Gura and Christina Ruffini, hosts of “Bloomberg This Weekend,” to discuss briefing the U.S Senate on regulating AI, in wake of recent reports of rogue agents. “I want to emphasize for anyone who gets stressed by this, that this dystopian future where we build smarter than human AIs and robots, super intelligence, and then they take over Earth, is not at all inevitable,” says Tegmark.  

Cailin Plunkett speaks to the Scientific American’s Mary Randolph about her research discovering that 14% of black holes may be hierarchical mergers, made from the merger of two smaller black holes. “At minimum, we’re finding evidence that there are these highly spinning and weirdly tilted black holes in the dataset, and the most straightforward way to interpret that, the Occam’s razor answer, is that these black holes probably came from previous mergers,” says Plunkett.  

In a Scientific American article by reporter Joseph Howlett, Prof. Naomi Sweeting discusses the potential pitfalls of consulting artificial intelligence in mathematics. “I view math as part of a vast and beautiful human project,” says Sweeting. “It's this huge endeavor that puts us in communication with thousands of years of human thinking.”
