NOVA program host Alok Patel explores the benefits of sharing personal data without compromising personal privacy. He visits Prof. Ramesh Raskar’s Camera Culture Lab, where Raskar discusses the concept of “smashing data” - the process of extracting useful information while obscuring private data. “Achieving privacy and benefits of the data is available, and it’s just a matter of convincing large companies to play along those rules,” said Raskar.
MIT researchers have discovered three of the oldest stars in our universe among the stars that surround “the distant edge of our Milky Way galaxy,” reports Jess Thomson for Newsweek. “These stars, dubbed SASS (Small Accreted Stellar System stars), are suspected to have been born when the very first galaxies in the universe were forming, with each belonging to its own small primordial galaxy,” explains Thompson.
Researchers from MIT and elsewhere have discovered a celestial body, which has been called “the second lightest planet ever discovered,” reports Eric Lagatta for USA Today. “The star-orbiting exoplanet outside of our solar system is about seven times less massive than Jupiter, which is why astronomers compare its low density to cotton candy,” Lagatta explains.
MIT astronomers have discovered an exoplanet with a density similar to cotton candy, reports Newsweek’s Jess Thomson. The planet, “named WASP-193b, is the second-least dense exoplanet ever found, with a density of around 0.059 grams per cubic centimeter, or 3.68 pounds per cubic foot,” Thomson explains. “This makes it about 7 times less dense than our neighboring planet Jupiter, despite being 50 percent larger in size, and about 1 percent the density of our own planet.”
An opinion piece by Katie Martin of the Financial Times explores how Prof. Emil Verner and colleagues have found that climate pledges made by banks and other financial institutions are not effective at reducing carbon emissions. “We find no evidence of reduced financed emissions through engagement,” the paper states. “We conclude that net zero commitments do not lead to meaningful changes in bank behavior.”
Prof. Anna Frebel and her colleagues have identified some of the oldest stars in our universe, located in the Milky Way’s halo, a discovery that stemmed from Frebel’s new course, 8.S30 (Observational Stellar Archaeology), reports Isaac Schultz for Gizmodo. “Studying the ancient stars won’t only help explain the timeline of stellar evolution, but also how our galaxy actually formed,” Schultz explains.
An international team of astronomers, including scientists from MIT, discovered an exoplanet with an “exceedingly low density for its size,” reports Marcia Dunn for the Associated Press. The planet “is ideal for studying unconventional planetary formation and evolution,” explains Dunn.
MIT researchers have developed microneedle patches that are capable of restoring hair growth in alopecia areata patients, reports Ernie Mundell for HealthDay. The team’s approach includes a, “patch containing myriad microneedles that is applied to the scalp,” writes Mundell. “It releases drugs to reset the immune system so it stops attacking follicles.”
Researchers from the Department of Air Force-MIT Artificial Intelligence Accelerator are applying new AI technologies to assist with everything from pilot communication to developing an AI alternative to GPS satellite-dependent navigation, reports Associated Press reporter Tara Copp.
Researchers from MIT and elsewhere have used quantitative and computational methods to analyze animal communication, reports Emily Anthes for The New York Times.
MIT researchers have developed “an ultra-thin silk fabric embedded with a special piezoelectric fiber that can vibrate to cancel out noise in a room,” reports Bob McDonald for CBC. “The researchers want to further study how changing elements of the fabric — such as the number of piezoelectric fibers and the voltage they apply to it, the direction they're sewn into the fabric, and the size of the pores in the fabric — can improve on their findings,” writes McDonald.
An analysis by MIT researchers has identified “wide-ranging instances of AI systems double-crossing opponents, bluffing and pretending to be human,” reports Hannah Devlin for The Guardian. “As the deceptive capabilities of AI systems become more advanced, the dangers they pose to society will become increasingly serious,” says postdoctoral associate Peter Park.
Researchers from MIT and elsewhere have found that “showing AI-generated images of a less car-reliant American city boosted support for sustainable transportation policies,” reports Linda Poon for Bloomberg. “Let’s help them imagine what it would actually be like to live in a car-less neighborhood, and a car-less city,” says postdoctoral associate Rachit Dubey.
MIT researchers have developed a new procedure that uses game theory to improve the accuracy and consistency of large language models (LLMs), reports Steve Nadis for Quanta Magazine. “The new work, which uses games to improve AI, stands in contrast to past approaches, which measured an AI program’s success via its mastery of games,” explains Nadis.
MIT researchers have used advancements in machine learning and computing to help decode whale vocalizations, reports Sarah Kuta of Smithsonian Magazine. “If researchers knew what sperm whales were saying, they might be able to come up with more targeted approaches to protecting them,” Kuta explains. “In addition, drawing parallels between whales and humans via language might help engage the broader public in conservation efforts.”
