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?”

In a new LinkedIn ranking, MIT has been named one of the best colleges for long-term career success “because of its place in the top 5 for entrepreneurship, C-suite experience (CEO, CFO, etc.), internships, and recruiter demand,” reports Madison Lucchesi for Boston.com. 

MIT has been named among the top US schools for long-term career success in a new LinkedIn ranking, reports Ava Berger for The Boston Globe. “The list compiles public member data from the networking platform based on five factors: job placement, internships and recruiter demand, career success, network strength, and 'the unique skills' gained by graduates,” writes Berger. 

Researchers at MIT have proposed that liquids, such as ionic fluids, are “what’s important for extraterrestrial habitability, and not just water,” reports Gayoung Lee for Gizmodo. If confirmed, this research would “dramatically expand what’s considered the ‘habitable zone’ among known exoplanets,” writes Lee. “By current standards, the habitable zone is defined as the band within planetary systems in which liquid water can remain stable on the surface. When it comes to life, we’re understandably biased towards water; all life as we know it depends on it.”  

Graduate student Megan Masterson speaks with CBS Eye on the World hosts John Batchelor and David Livingston about her research on tidal disruption events. “These events were first theorized in the 1970s, first discovered in the 1990s with x-ray wavelengths,” explains Masterson. “But today, what James Webb is doing is allowing us to detect these events in the infrared band. And so, what we’re seeing here are previously dormant black holes that were kind of lying at the center for their galaxies doing pretty much nothing suddenly become active.” 

Researchers at MIT have developed a new tool, called Meschers, that allows users to create detailed computer representations of mathematically impossible objects, reports Gayoung Lee for Gizmodo. “In addition to creating aesthetically quirky objects,” Lee explains, “Meschers could eventually assist in research across geometry, thermodynamics, and even art and architecture." 

A new study by MIT researchers has “identified the parts of the brain’s visual cortex that respond more when we look at things (rigid objects like a stone skipping or a bouncing ball) vs stuff (liquids or something more granular like sand). Understanding this distinction may help our brains better plan how to interact with various materials,” explains Lauren Baisas for Popular Science. “Understanding this distinction may help our brains better plan how to interact with various materials,” explains Baisas. 

Writing for Physics Today, Prof. Camilla Cattania and her colleagues highlight the impact of big data and AI advancements in improving the reliability of earthquake forecasting and prediction. “Advances in technology and data analysis, particularly the incorporation of AI techniques, are driving the development of more-sophisticated forecasting models,” they write. “Advances in sensor technology and the expansion of dense seismic networks are providing new insight into the dynamics of Earth’s crust. That wealth of data enables the creation of more detailed and nuanced forecasting models that better capture the complexities of earthquake processes.”
