Cambridge Day’s Chloe Taft spotlights the 25th anniversary of The Fab Lab, digital fabrication network started at MIT, and its annual conference, FAB26, held this week throughout Cambridge. “We’re going to show things like rapid prototyping, making vehicles [at FAB26],” says Prof. Neil Gershenfeld. “[T]here’s examples of using the tools in the lab to make aquaponic and hydroponic systems for food, to make antennas and radios for data networks, to make shelter. You really can make almost anything today.” 

Researchers from MIT and Toyota Research Institute developed SceneSmith, a system that allows robots to practice everyday tasks and action plans in over 1,300 AI generated environments before entering a real home or workplace, writes Fox News’ Kurt Knutsson. “SceneSmith's ability to combine realistic design with usable physics gives the project its strongest advantage,” notes Knutsson.  

Graduate student Peter Zhi Xuan Li speaks to Tech Briefs’ Andrew Corselli about his team’s work developing a new chip that allows small, autonomous robots and other battery-limited devices to construct detailed 3D maps of their environments using a fraction of the power required by other systems. “Today, a robot uses separate, incompatible internal representations for different jobs: one for mapping, another for tracking its own motion, another for rendering what it sees, and every conversion adds memory footprint and energy,” says Li. “Our goal is a single shared representation.” 

By studying ‘smears’ in fast radio bursts, fleeting flashes of radiation, MIT researchers discovered diffuse clouds of baryonic gas may contain the missing ordinary matter in the universe, writes Gizmodo’s Gayoung Lee. “These diffuse clouds may be flung outside galaxies through black hole jets,” Lee explains. 

After analyzing data from the LIGO, Virgo and KAGRA gravitational wave detectors, MIT researchers have found that 14% of black holes may be second-generation, formed by the merger of two smaller black holes, writes Gayoung Lee for Gizmodo. The scientists “created an analytic model to capture the kind of wobble that would have emerged from second-generation black holes. Around 14% of merging black holes followed this pattern, and the second-generation black holes identified had a very specific range of masses, at around 20 solar masses or 40 solar masses and above,” Lee explains.  

A study by MIT researchers has found evidence that the first signs of ozone depletion appeared in 1957 in the upper tropical stratosphere, driven by carbon tetrachloride, an industrial chemical introduced in the 1930s and widely used as a dry-cleaning and degreasing agent, writes Gizmodo reporter Ellyn Lapointe. “This finding underscores the importance of long-term atmospheric monitoring so that we can fully understand how it responds to chemical pollution,” Lapointe notes.

Writing for IEEE Spectrum, reporter Matthew S. Smith highlights Fractal, a new operating system hand-coded by CSAIL researchers to provide a clear view of security vulnerabilities. “We paved the way with techniques such as custom kernel patches and kernel extensions,” says graduate student Joseph Ravichandran. “The dream was always to have a completely custom operating system which would make these hacks unnecessary.”

MIT engineers have developed a new low-temperature process for extracting battery-grade lithium from hard rock, while also reducing waste, reports Gayoung Lee for Gizmodo. “Mining is essential to technology and therefore to society, yet it is perceived negatively by much of the public as a destructive, polluting industry, in some cases with good reason,” explains Prof. Yet-Ming Chiang. “We hope to help change that perception by showing that there are cleaner, more sustainable ways to do it.”

MIT researchers have developed a new method for precisely moving columns of individual atoms within a material, which could give rise to exotic quantum properties and shed light on quantum behavior, reports Tim Wogan for Physics World. “I’m excited because of the scalability of this that allows us to look at the interactions between the defects rather than just creating a defect itself,” explains Prof. Frances Ross. 

Researchers from MIT have created a new model that can predict wave behavior on different planets, reports Kristen French for Nautilus. “On Earth, waves form as wind drags across bodies of water, pushing unevenly on their surfaces. As the waves lengthen, and the distance between crests grows, the waves are increasingly driven by the force of gravity rather than by surface tension,” French writes. “On faraway planets, the size of the waves would depend not only on the strength of gravity and the speed and direction of the wind, but the density of the atmosphere, the viscosity of the liquid in the oceans and lakes, as well as the depth of the bed. All these factors were fed into the PlanetWaves model.” 

MIT scientists have developed a new model, dubbed "PlanetWaves," that predicts wave behavior on different planets, showing that the "smallest gust of wind on Titan could generate huge, roiling waves across seas of hydrocarbons," reports Andrew Paul for Popular Science. “PlanetWaves is far more than a novel simulator,” writes Paul. “Calculating fluid behaviors on distant planets and moons could help inform engineers building new spacecraft and probes.”

Scientific American reporter Bob Henderson spotlights how graduate student Jiaruo Li and Prof. Riccardo Comin are developing a new device for storing digital data using “an exotic kind of magnetism discovered in the same lab the previous year to make the device faster and more energy-efficient than any competing technology.” 

MIT researchers have developed a new traffic navigation system that more accurately reflects travel time by including parking data, reports Catherine Parotta for Boston 25. “What we can do is figure out if you’re best off trying this parking lot first, even if it’s farther than the closest parking lot,” explains Prof. Cathy Wu. Graduate student Cameron Hickert adds that: “We hope that this can help people make better decisions." 

Prof. David Kaiser and graduate student Alexandra Klipfel speak with New York Times reporter Dennis Overbye about their theory that a neutrino detected zipping through the Mediterranean Sea in February 2023 may have come from an exploding primordial black hole. Kaiser and Klipfel "concluded that if primordial black holes were the explanation for long-sought dark matter, scientists should expect about 40 black-hole explosions to occur each year in every cubic light-year near the Milky Way,” Overbye notes. 

Prof. Salvatore Vitale and graduate student Jack Heinzel speak with Scientific American reporter K.R. Callaway about the LIGO-Virgo-KAGRA (LVK) Collaboration’s latest catalog of gravitational wave detections, which “more than doubles the number of gravitational-wave candidate events—and reveals unexpected complexities of merging black holes.” Says Heinzel: “We’re learning a lot of things that are qualitative and phenomenological from the catalog. Starting to see all these different structures emerge is pretty fascinating.”
