Prof. Jonathan Weissman speaks with The New York Times’ Emily Baumgaertner Nunn about epigenome editing, including a single injection that would silence a gene in the liver that destroys receptors responsible for clearing LDL cholesterol. “This is sort of the ultimate one-and-done treatment,” says Weissman. “I don’t think we know enough to be able to do it at the moment, but it is not so far off from what’s imaginable.”  

MIT researchers have discovered that peptides “not only survive in highly concentrated sulfuric acid but take on stable 3D conformations too,” writes Chemical & Engineering News’ Fionna Samuels. “The project started with a new collaboration between [Prof. Sara] Seager and the MIT chemist [Prof.] Mei Hong,” notes Samuels. “In the years since finding phosphine signals in Venusian clouds, Seager had been working her way through the building blocks of life—nucleic acids, amino acids, and lipids—to see if any survived concentrated acid exposure.”  

MIT researchers have developed an AI-powered robotic therapy system that combines wearable force sensors and camera recordings of physical therapists’ movements to provide personalized therapy to patients, writes Newsweek’s Claudia Tanner. “Robotic assistance will allow patients to practice exercises more often while still receiving support tailored to their abilities,” says Johannes Lachner, who completed this work as a postdoctoral fellow at MIT. “Our goal is to take a step toward more accessible and personalized physical rehabilitation, giving more patients the opportunity to regain movement and independence.” 

According to new research by MIT physicists, a laser able to capture neutrinos, abundant yet intangible particles in the universe, is likely impossible to build, writes New Scientist’s Karmela Padavic-Callaghan. “The key to the neutrino laser proposal was a memory effect: when an atom in the BEC (Bose-Einstein condensate) emitted a neutrino, it would be more likely to continue emitting more neutrinos in the same direction, thus pushing them into a beam, because the quantum state that all the ultracold atoms share would retain a trace of that first emission,” Padavic-Callaghan explains. “[Prof. Wolfgang] Ketterle and his colleagues showed that this memory, although present, would be about 10,000 billion times too brief to affect the neutrinos as intended.” 

Prof. Susan Solomon joins Cleo Abram’s “HUGE* If True,” to discuss her 1985 research uncovering how chlorofluorocarbons, were depleting the ozone layer, which led to the Montreal Protocol that banned the use of those chemicals. “It was an interesting feeling being under the ozone hole, knowing that half a world away an incredible change [the Montreal Protocol] had just occurred that really had a lot of potential to change things in the future—and indeed it did,” says Solomon.  

Prof. Emeritus Kerry Emanuel speaks to The New York Times’ William J. Broad about the use of AI models in predicting hurricanes. “It’s human beings who have to make these calls,” says Emanuel. “[Eventually] AI will be treated as just another form of guidance” along with satellite images and readings from hurricane hunter aircraft that pierce the tempests. 

Graduate student Jaida Elcock speaks to Popular Science’s Laura Baisas about tagging a whale shark about 100 miles off the coast of New England, as part of an effort to learn more about the behavior of these giant sea creatures, in the biodiverse northeast canyon and seamounts region of the Northwest Atlantic Ocean. “There are whale shark aggregations all over the place. The Philippines, Mexico, Australia, tropical places like that. A lot of these aggregations are also often young individuals, subadult individuals, juveniles,” says Elcock. “Out in the [northeast] canyons, we’re seeing large adults.” 

MIT researchers found that unless an individual is affected by stroke or dementia, their ability to process language does not decline with age, writes Health Day’s Dennis Thompson. “Scans show that activity in the brain’s language processing network is nearly identical among seniors to that found in younger adults,” writes Thompson. “These results indicate that parts of the brain dedicated to unique functions like language might be less prone to age-related decline than general-purpose networks that contribute to many different skills.”  

Postdoctoral Associate Rohan Naidu joins John Batchelor and David Livingston, hosts of the “Hotel Mars” podcast, to discuss his research discovering black hole stars from little red dots using NASA’s James Webb Space Telescope. “When we first discovered the little red dots, we assumed that red means dust, and so the idea was that the little red dots are the kind of black holes that we see in our backyard,” says Naidu. “But now we have this paradigm shift where we are realizing that red does not mean dust. Red could mean that you have this black hole star kind of object where all the blue light is being soaked up in this dense star-like cocoon.” 

Sonia Vallabh, Director of Prion Therapeutic Science at the Broad Institute of MIT and Harvard, speaks to Nature’s Josie Glausiusz about her journey co-leading an initiative to develop preventive drugs for prion disease, a rare, lethal neurodegenerative disease that is caused by misfolded proteins that kill neurons. “In pre-symptomatic people at risk, if we can lower the amount of normal protein, I’m hoping we can delay or even prevent the formation of the first misfolded prion,” says Vallabh.  

Prof. Erin Kara speaks to NPR’s Ari Daniel about how the fastest star ever observed in the galaxy, located next to the Sagittarius A* black hole, experiences how space and time are distorted by the black hole. “This is a really exciting result," says Kara. "It kind of sets the stage in the next decade to make these kind of unprecedented measurements of black holes.” 

Prof. Max Tegmark joins Steve Clemons, host of Al Jazeerah’s, “The Bottom Line,” to discuss regulating AI. “Normally with technology we have a problem we want to solve: cure cancer, be able to get faster from point A to point B, and then we develop technology to meet those needs, to solve those problems—and that’s how we should deal with AI also,” says Tegmark. “We should look at what we would like to have accomplished in our society and then companies can sell products that solve those problems without causing a bunch of harm.” 

By analyzing brain scans from 772 people, MIT researchers have identified 17 additional language-responsive regions in the brain, reports The Dallas Express (DX). “For decades, scientists have focused on regions such as Broca’s area and areas of the left frontal and temporal lobes as the brain’s primary language-processing centers,” writes DX. “The new study found that language-responsive regions are also located in other parts of the brain, including the cerebellum, hippocampus, amygdala, medial frontal cortex, and temporal lobe.”  

Popular Science’s Andrew Paul spotlights how MIT astronomers have identified a black hole star (MoM-BH*-1), a gigantic, dense gas cloud fueled by a central black hole, discovered in an image of a large red dot on NASA’s James Webb Space Telescope (JWST). “The groundbreaking realization and newest addition to the cosmic catalogue wouldn’t have been possible without the JWST, whose smallest discoveries have massive ramifications,” writes Paul. “Even something as tiny as a 100-million-year-old red dot.” 

Using NASA’s James Webb Space Telescope (JWST), MIT researchers have discovered a black hole star, MoM-BH*‑1, the earliest example of a black hole in the universe, writes Mashable’s Elisha Sauers. “We argue that Black Hole Stars may be powering all of JWST's Little Red Dots that are found almost everywhere in the early Universe,” says Postdoctoral Associate Rohan Naidu. “Which is to say, this channel of making massive black holes must be very common, to the point where every massive black hole (like the Milky Way's) may have gone through this phase.”
