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.
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.
BBC Science Focus reporter Alex Hughes spotlights a new study by MIT scientists that suggests more heavy snowfall and rain linked to climate change could increasingly contribute to earthquakes worldwide. “The researchers made these conclusions based on how weather patterns in northern Japan have seemingly contributed to a new 'swarm' of earthquakes,” writes Hughes, “a pattern of multiple, ongoing quakes – that is thought to have begun in 2020.”
A new study conducted by MIT researchers suggests “heavy snowfall could be a factor in triggering swarms of earthquakes,” reports Evan Bush for NBC News. "Those big snowfall events seem to correlate well with the start of these big earthquake swarms," says Prof. William Frank. "We shouldn’t forget the climate itself can also play a role in changing the stress state at depth where earthquakes are happening."
Interesting Engineering reporter Sujita Sinha spotlights how MIT researchers crafted a special silk fabric capable of blocking sound. “Inside this special material is a fiber that springs to life when an electrical charge is applied,” explains Sinha. “The fabric starts shaking when it hears sound, which helps stop noise in two different ways.”
Researchers at MIT and elsewhere have investigated “how several species of parrots interacted when placed on brief video calls with one another,” reports Mack Degeurin for Popular Science. “The results were shocking,” explains Degeurin. “In almost all cases, the birds’ caretakers claim the video calls improved their well-being. Some of the birds even appeared to learn new skills, like foraging or improved flight, after observing other birds doing so.”
Scientists from MIT and the University of Oxford have discovered that an ancient sequence of rocks found in Isua, Greenland have “a magnetic field strength of at least 15 microteslas or higher compared to the modern magnetic field of 30 microteslas,” reports David Bressan for Forbes. “These results provide the oldest estimate of the strength of Earth’s magnetic field derived from whole rock samples,” writes Bressan.
Prof. Earl K. Miller speaks with CBS News host Susan Spencer about multitasking, fear of laziness, and the importance of downtime. “A lot of times some of your best thoughts come to you when your conscious mind is out of the way, when you allow the unconscious thoughts to bubble up,” says Miller. “And sometimes it’s good to be lazy – not lazy, but to tune out a bit and let these thoughts bubble up.”
MIT researchers have “discovered hitherto unknown space molecule while investigating a relatively nearby region of intense star birth,” reports Robert Lea for Space.com. This discovery “revealed the presence of a complex molecule known as 2-methoxyethanol, which had never been seen before in the natural world, though its properties had been simulated in labs on Earth,” writes Lea.
Researchers from MIT and elsewhere have found that a sequence of rocks from the Isua Supracrustal Belt in Greenland contain “an ironclad record of the early Earth’s magnetic field,” reports Keith Cooper for Space.com. “The new results from the Greenland rocks are considered more reliable because, for the first time, they are based on entire iron-bearing rocks (rather than individual mineral crystals) to derive the primordial field strength,” explains Cooper. “Therefore, the sample offers the first solid measure of not only the strength of Earth's ancient magnetic field, but also of the timing of when the magnetic field originally appeared.”
Bloomberg Opinion columnist Parmy Olson spotlights a new study by MIT researchers that finds AI chatbots can be highly persuasive when reinforced with facts and could potentially be used to help tackle conspiracy theories. “The scientists invited more than 2,000 people who believed in different conspiracy theories to summarize their positions to a chatbot — powered by OpenAI’s latest publicly available language model — and briefly debate them with the bot,” Olson writes. “On average, participants subsequently described themselves as 20% less confident in the conspiracy theory; their views remained softened even two months later.”
MIT scientists have uncovered evidence that the different layers of the brain’s cortex generate different brain waves, reports Simon Makin for Scientific American. “The findings may have implications for understanding—and even treating—neuropsychiatric conditions,” Makin explains.
