Research Scientist Judah Cohen speaks to CNN’s Laura Paddison and Brandon Miller about the potential for El Niño to drive away cold air from the current weakened polar vortex. There’s an assumption that “El Niño is kind of this runaway freight train, and nothing’s going to get in the way of it,” says Cohen. But “whether there’s cold air or not will depend on the behavior of the polar vortex.”
A study by MIT scientists finds that listening to short, timed bursts of pink noise during sleep can encourage the flow of cerebrospinal fluid, which clears the brain of “harmful particles that increase your risk for neurodegenerative disease,” writes Scientific American reporter Alex Music. “If validated by future work, selective noise-playing could potentially unlock more restorative sleep in a home environment,” notes Music. “They’re particularly interested in testing the method in older individuals and in people with sleep disorders.”
The conversational AI models developed by MIT spinout Liquid AI are being introduced in Mercedes-Benz cars, writes Isabelle Bousquette for The Wall Street Journal. “Liquid AI invented a new architecture known as liquid neural networks, adaptive and efficient systems inspired by the neural activity of worms known scientifically as C. elegans,” writes Bousquette. Using the Liquid AI models in vehicles instead of cloud-based AI systems could allow for more “privacy, speed and the ability to run without constant network connectivity.”
Prof. John Hansman speaks to Scientific American reporter Peter Hall about the development of self-flying cargo planes. “We’ve been flying unmanned air vehicles, or drones, of reasonably large size,” for a while, says Hansman. “A small quadcopter drone doesn’t have to have the level of redundancy that a large vehicle that could hurt people on the ground or carry people needs.” However, “there will always be some level of human supervision,” even if the safety pilot is taken out of the cockpit in the years to come, Hansman adds.
Research Scientist Judah Cohen speaks to USA Today’s Doyle Rice and Dinah Voyles Pulver about the potential impacts of the sudden stratospheric warming (SSW), currently disrupting the polar vortex, that “could eventually lead to an outbreak of frigid air across much of the United States at some point over the next few months.” “Usually it takes two weeks (but recently it seems to take much longer) for the impacts of the SSW to impact our weather, so that puts it as early as late November but more likely in December and could even be delayed until January,” says Cohen. “The last El Niño in 2023-24 featured two SSWs and it was a very mild winter in the eastern U.S. and may have even been record mild. In short lots of uncertainty!”
Visiting Scholar Ariel Ekblaw SM ’17, PhD ’20 speaks with CNN’s Amy Gunia about her work developing TESSERAE, a space architecture project involving magnetic, self-assembling tiles that could one day be used to create structures in space. “The tiles can be stacked on top of each other inside a rocket and released in space, where they can autonomously attach to each other—employing electro-permanent magnets, cameras and AI—to create a predetermined shape,” Gunia explains. The tiles “can self-assemble into something way bigger than the size of the rocket that they came up in,” Ekblaw shares, which could allow humans to build “science-fiction-worthy, big, grand structures” in space.
Mike Beigel ‘70, who invented Mu-Tron III, considered to be “the first commercial envelope filter pedal [that] allowed guitar players to achieve a synthesizer-like sound” used in popular 1970s music, has died at 79, reports Alex Williams for The New York Times. “The Mu-Tron III was the most renowned of several effects pedals that Mr. Beigel invented for Musitronics, a New Jersey-based company that he co-founded in 1972,” writes Williams. Musitronics, “produced a variety of sought-after pedals, including the Mu-Tron Octave Divider, Phasor, Flanger and Bi-Phase, which have been adopted by notables like Neil Young, Billy Corgan of the Smashing Pumpkins and John Frusciante, the Chili Peppers guitarist.”
CodeSignal, co-founded by alumnus and CEO Tigran Sloyan, has developed Agentic Skills Intelligence, a new product that “uses AI agents to evaluate the skills people use in their work and links the findings to personalized practice,” writes Forbes’ Ray Ravaglia. CodeSignal has built an AI agent “for each domain in its job taxonomy, such as engineering and sales, along with agents for capabilities that cut across jobs, among them communication and AI literacy,” notes Ravaglia. “The agents draw on systems including Gong, Salesforce, and GitHub, and they score what they find against rubrics the company says are grounded in industrial-organizational psychology.”
BIOSENTER, a soft, snake-like robot developed by MIT researchers, could autonomously snap photos, administer drugs, and take small biopsy samples within cramped and difficult to reach areas of the body such as the small intestine, writes Mack DeGeurin for Popular Science. “BIOSENTER has four inflatable chambers arranged along either side of its tubular body. These chambers inflate and deflate in alternating combinations, which is how it moves [forward] and bends to change directions,” explains DeGeurin. “Keeping with the snake theme, the robot’s exterior is fitted with a textured, scale-like coating that improves its traction.”
Prof. Sanjay Sarma speaks to Bloomberg’s Saritha Rai about the difficulty of developing dexterous robots for use in the home versus developing factory machines for use in standardized plants. “Heavy work, hazardous tasks have long been the focus of automation,” says Sarma. “Robots seem to be following an evolutionary path–the finer the motor or cognitive skills required, the harder to automate.”
MIT researchers have developed BIOSENTER, a soft robot inspired by the movement of snakes, “designed to navigate the twists and turns of the small intestine [that] could perform real-time imaging, deliver drugs, and take biopsies deep within the digestive tract,” reports Inside Precision Medicine. “The robot’s tube-like body contains four inflatable chambers that can expand or contract in different combinations, allowing the robot to move forward and bend in different directions. A hollow central channel allows the robot to carry endoscopic tools, including a camera for imaging, a fluid sprayer for drug delivery, and clips for collecting tissue samples or removing small polyps.”
Arcaea, a biotech beauty company founded by CEO Jasmina Aganovic ‘09, has partnered with the actress and producer Jennifer Lawrence to develop mes°, a new haircare brand, reports Flavio Gomez for the Los Angelos Times. “A TED Talk by Aganovic, an MIT-trained chemical and biological engineer exploring how biology can open new possibilities in beauty, prompted the two to connect and eventually develop the brand,” notes Gomez. “Instead of treating each [hair] concern as an isolated problem, the brand looks to biology for ways to address it.”
Prof. Ryan Williams speaks to TechCrunch’s Tim Fernholz about AI platforms refuting the Exponential Time Hypothesis, part of a broader class of problems known as P versus NP. “I do think that it kind of calls into question a lot of the intuitions that we thought we had about … how tractable [hard NP problems] are. I also think that this is probably not the final answer either,” says Williams. AI is “forcing people to be a little more ambitious about the kind of work that they do, and to think more deeply about, okay, if all the things I used to work on are now low-hanging fruit for AI, how can I raise the bar for the kind of scientific questions I want to ask?”
Research Scientist Judah Cohen joins Fox News to discuss the potential for a historic, massive polar vortex disruption, or early season weakening, that “could send atmospheric impacts rippling across the planet in the weeks or even months to come.” Cohen says, “this will, I think almost undoubtedly, be the largest, earliest disruption of the polar vortex on record. What the impacts could be on a regional basis is really hard to know. Everything is possible. Traditionally it [the disruption] is thought to bring colder and snowier weather to the eastern U.S. about two weeks after the event kind of peaks, but in recent history that has not been the case.”
Prof. Suraj Cheema joins Edgar B. Herwick, host of GBH’s “The Curiosity Desk,” to discuss the functionality and global development of computer chips. “The know-how of how to make these chips is very specialized,” says Cheema. “Imagine there’s 100 steps in the process, not just that printer that costs a few $100 million, just all these other kinds of steps that go along with it. We have 20 million transistors in this little chip. We want them all to work. They all have to work [for the chip to function].”
