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 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.
Prof. Asegun Henry founded Fourth Power, a startup using new technology to cut the cost of storing renewable energy, reports Adele Peters for Fast Company. The technology is designed “to tap into excess renewable energy,” explains Peters. “That energy heats up liquid tin, which flows down carbon pipes to heat up the blocks. When the grid needs electricity again, the system generates it using special solar panels that run on the white-hot light from the pipes rather than sunshine. Because the system was designed for durability, the team expects it to last for three decades—far longer than lithium-ion batteries, which quickly degrade.”
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.”
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 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.”
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.
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.
Writing for The Architect’s Newspaper, James McCown describes the glass curtain wall at the new MIT Schwarzman College of Computing. “Artificial intelligence will be one of the chief research initiatives taking place at Schwarzman,” McCown notes. With all of its transparency, here MIT and SOM have created a powerful gesture of openness and accountability—a crucial perspective as AI technology advances in ways that are both exciting and foreboding.”
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.
An analysis by The Atlantic’s Ronald Brownstein notes despite Republican resistance to electric vehicles, many new production facilities are located in GOP-represented states. MIT Innovation Fellow Brian Deese explains EV companies are simply seeking space and nearby manufacturing and construction capacity, but said “it’s pretty hard to think of a technology where there was a cheaper, better technology to solve a consumer need and consumers prioritized a cultural or political patina over lower costs and higher quality.”
Alex Viega of the Associated Press reports on the death of former MIT Prof. James Simons '58, a life member emeritus of the MIT Corporation and “a renowned mathematician and pioneering investor who built a fortune on Wall Street and then became one of the nation’s biggest philanthropists.” Simons and his wife Marilyn co-founded the Simons Foundation, whose president said, “Jim was an exceptional leader who did transformative work in mathematics and developed a world-leading investment company.”
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.
