Prof. Nergis Mavalvala, dean of the MIT School of Science, joins Bob McDonald of CBC’s “Quirks & Quarks” to discuss how 10 years after LIGO’s first detection of gravitational waves the observatories are still “helping scientists better understand the life cycles of stars, the nature of gravity, and transforming the way we explore the farthest reaches of space.” Mavalvala shares: "Scientists have been able to design and construct these instruments that are capable of measuring imperceptibly small changes in spacetime distance, and in the past 10 years the sensitivity of these instruments has improved. That’s what is allowing us to make greater discoveries.” 

Prof. Richard Binzel spoke at the Europlanet Science Congress (EPSC) about efforts to create a system that could help deflect deadly asteroids away from Earth, reports Alex Wilkins for New Scientist. “If we had to deal with an actual asteroid threat,” says Binzel, “we would certainly want to know these properties, like the spin or tumbling state [of an asteroid].”

Writing for The New York Times, Dennis Overbye celebrates the 10-year anniversary of LIGO’s first direct detection of gravitational waves, underscoring how LIGO has advanced our understanding of the universe’s cosmic history. The first detection was a discovery that “changed astrophysics, opening a window onto previously inaccessible realms of nature in which space could rip, bend, puff up, crumple and even vanish,” writes Overbye. The late Prof. Emeritus Rainer Weiss, who dreamed up the idea for LIGO, said of LIGO’s first detection in September 2015: “It was waving hello. It was amazing. The signal was so big, I didn’t believe it.”

The Cambridge Science Carnival, founded by the MIT Museum, will take place on September 21, 2025, in the Kendall/MIT Open Space, reports The Boston Globe. The event features “more than 100 booths with science and art based activities and demonstrations,” writes The Boston Globe. From a STEAM-themed playground to “live, interactive music from the MIT physics departments,” kids are welcome to play, learn and enjoy. 

Forbes reporter Martina Castellanos spotlights Edwin Chen '08, founder of Surge AI, as one of the 10 youngest billionaires on the 2025 Forbes 400 list. After working in machine learning, Chen saw “the lack of quality training data for AI,” and “launched Surge AI in 2020 to fix the problem,” writes Castellanos. 

Writing for Nature, Bruce Allen pays tribute to Prof. Emeritus Rainer Weiss, a pioneering physicist who “spearheaded the construction of the LIGO observatory to detect Einstein’s predicted ripples in space-time [and] leaves a legacy of persistence and mentorship.” Allen recalls how, decades earlier, Weiss rejoiced in a moment of discovery with him. “This is why we do science,” Weiss said. “Not for prizes or awards — that’s all nonsense. It’s for the satisfaction when something you’ve struggled with finally works.” Weiss, Allen emphasizes, was “a scientist driven by curiosity, persistence and the joy of understanding how the Universe works.”

Researchers at MIT have developed the first full map of the quantum landscape that constrains how electrons move inside matter, reports Karmela Padavic-Callaghan for New Scientist. The map “offers a new way to understand and design materials, perhaps leading to, for instance, super-efficient wires that conduct electricity with no resistance,” Padavic-Callaghan explains. “A new view of what actually happens inside materials is bound to lead to new ways to improve them.” 

David Baltimore, a former Institute Professor at MIT and a Nobel laureate, has passed at the age of 87, reports Gina Kolata for The New York Times. Baltimore’s work rocked “the foundation of the fledging field of molecular biology,” writes Kolata. His “Nobel-winning discovery [upended] what was called the central dogma, which stated that information in cells flowed in only one direction — from DNA to RNA to the synthesis of proteins. Dr. Baltimore showed that information can also flow in the reverse direction, from RNA to DNA.” 

Wall Street Journal reporter Jon Mooallem memorializes the life and work of Prof. Emeritus Rainer Weiss, from his time hacking surplus military electronics into sophisticated hi-fi receivers as a teenager to dreaming up the concept for the Laser Interferometer Gravitational-Wave Observatory (LIGO). Mooallem notes that Weiss and his LIGO colleagues’ breakthrough in achieving the first-ever detection of gravitational waves “has provided a new way of looking at the universe, of observing, through the charting of gravity waves emitted by moving objects, what was previously unobservable or unknown—a milestone that is frequently compared with Galileo’s invention of the telescope.”

Gizmodo reporter Gayoung Lee writes that scientists from the sPHENIX Collaboration, including MIT physicists, announced that the sPHENIX detector passed a “standard candle” test with “flying colors, correctly catching and measuring the energy level of colliding gold ions traveling close to the speed of light.” Lee notes that: “Passing the test bodes well for the detector’s future,” explaining that the detector was designed to precisely measure products of high-speed particle collisions. “The sPHENIX detector is like a ‘giant 3D camera’ tracking the number, energy, and paths of particles generated by a single collision.” 

Prof. Rainer Weiss, a Nobel Prize-winning physicist whose research helped “unlock the secrets of the universe,” has died at 92, reports Bryan Marquard for The Boston Globe. “He really is, by a large margin, the most influential person this field has seen. And will see,” said Caltech Prof. Emeritus Kip Thorne. Nergis Mavalvala, dean of the MIT School of Science who conducted her doctoral research with Weiss, shared that Weiss “worked on three different things, and every one of them has changed the way we understand physics and the universe.”

Prof. Emeritus Rainer Weiss, a “renowned experimental physicist” who was “integral in confirming the existence of tiny ripples in spacetime called ‘gravitational waves,’” has died, reports Robert Lea for Space.com. “Remarkably, in confirming the existence of gravitational waves, Weiss both proved Einstein right and wrong at the same time,” writes Lea. “Einstein had been convinced that these ripples in spacetime were so faint that no apparatus on Earth could ever be sensitive enough to detect them, showing just how revolutionary LIGO was.”

Tri-City Herald reporter Annette Cary memorializes the life and legacy of MIT Prof. Emeritus Rainer Weiss, a “renowned experimental physicist and Nobel laureate,” who was “key to [the] world’s first gravitational wave discovery.” At the opening ceremony in June 2022 for the LIGO Exploration Center in Hanford, Washington, Weiss relayed how life is more interesting if you have a deeper understanding of the world around you and “how science does its tricks.”

Physics World reporter Michael Banks chronicles the life and work of MIT Prof. Emeritus and gravitational wave pioneer Rainer Weiss. “Weiss came up with the idea of detecting gravitational waves by measuring changes in distance as tiny as 10^–18 m via an interferometer several kilometers long,” writes Banks. “His proposal eventually led to the formation of the twin Laser Interferometer Gravitational-Wave Observatory (LIGO), which first detected such waves in 2015.” 

Professor Emeritus Rainer Weiss, a Nobel Prize-winning physicist who was honored for his work "developing a device that uses gravity to detect intergalactic events, like black holes colliding, and who helped confirm two central hypotheses about the universe,” has died at 92, reports Dylan Loeb McClain for The New York Times. In an earlier interview, Weiss reflected upon the wonder unlocked by LIGO: “With gravitational waves, you have a new way to look at [the] universe. You can see all that nature has in store. So now comes the question: What do you want to find out?”
