The Advanced LIGO Documentary Project commemorates the life and legacy of Prof. Emeritus Rainer Weiss, a recipient of the Nobel Prize in Physics and “LIGO’s heart and soul.” Said Weiss of the significance of detecting gravitational waves: "The discovery isn't the measurement of the gravitational waves…it's the black holes. That's absolutely spectacular... that this exists, and if you see a couple more, then you could say something about the universe. It's something new that we're going to be able to say about the universe. It's spectacular. To me, that's the big discovery."

George Smoot '66, PhD '70, who was honored for his work in cosmology with the 2006 Nobel Prize in Physics, has died at the age of 80, reports Douglas Scott, Joseph Silk and Tom Broadhurst for Nature. Smoot’s work “contributed to our understanding of the Universe on the largest scales and at the earliest observable times by measuring temperature variations in the cosmic microwave background,” they explain. 

Researchers at MIT have discovered “the most direct evidence to date of unconventional superconductivity in ‘magic-angel’ twisted trilayer graphene (MATTG), reports Aman Tripathi for Interesting Engineering. “This finding is a crucial step in the global search for room-temperature superconductors, often referred to as the ‘Holy Grail’ of physics,” writes Tripathi. 

Writing for Meteorological Technology International, Alex Pack explores how MIT researchers have developed a new “lightning-prediction model that could help protect more unconventional aircraft designs – such as blended-wing bodies or truss-braced configurations – as aviation moves beyond traditional tube-and-wing designs.” 

George Smoot '66, PhD '70, recipient of the 2006 Nobel Prize in Physics, has died at the age of 80, reports Katrina Miller for The New York Times. Smoot’s work as a physicist “helped elucidate the story of cosmic creation, providing evidence of what he called the primordial seeds that grew into galaxies and galaxy clusters,” writes Miller. 

Prof. Peter Shor speaks with Katia Moskvitch and her nine-year-old son Kai of The Quantum Kid about how quantum technologies could be applied to developing climate change and sustainability solutions. Shor explains that quantum computers can be used for “simulating quantum mechanics, which would really help immensely in designing new materials, and new materials could be very useful for solving the climate crisis.” 

George Smoot '66, PhD '70, the 2006 recipient of the Nobel Prize in Physics, has died at the age of 80, reports Kasha Patel for The Washington Post. Smoot’s work “helped take an image of the universe in its infancy, providing strong support for the Big Bang theory and new insight into the origins of the cosmos,” writes Patel. 

George Smoot '66, PhD '70, a recipient of the 2006 Nobel Prize in Physics for his work “finding the background radiation that finally pinned down the Big Bang Theory,” has died at age 80, reports the Associated Press. 

Researchers at MIT have developed magnetic transistors, “which could enable faster and more energy-efficient semiconductors,” reports Alex Knapp for Forbes. “Researchers have been trying to use magnets this way for years, but the materials used so far haven’t been optimal for computing functions,” explains Knapp. “That changed after experimenting with chromium sulfur bromide, which replaces the silicon in a conventional microchip and enables the transistors to be switched on and off with an electric current.” 

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.” 

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. 

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.” 

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.”
