Prof. Li-Huei Tsai, director of the Picower Institute, speaks with NPR host Jon Hamilton about her work identifying a protein called reelin that appears to protect brain cells from Alzheimer's. “Tsai says she and her team are now using artificial intelligence to help find a drug that can replicate what reelin does naturally,” says Hamilton.
Prof. R. Scott Kemp and Principal Research Scientist Charles Forsberg speak with Verge reporter Justine Calma about the nuclear proliferation concerns raised by the higher concentrations of uranium used in next-generation nuclear reactors. “We need to make sure that we don’t get in front of ourselves here and make sure that all the security and safety provisions are in place first before we go off and start sending [high-assay low-enriched uranium] all around the country,” says Kemp.
In an interview with The New York Times, Prof. Susan Solomon speaks about her latest book “Solvable: How We Healed the Earth, and How We Can Do it Again,” which offers learnings from past environmental fights to affect future change. “People need to have some hope. We imagine that we never solve anything…but it’s really important to go back and look at how much we succeeded in the past and what are the common threads of those successes,” Solomon says.
CNN’s Ashley Strickland reports on the discovery of an exoplanet on the path to becoming a “hot Jupiter,” providing clues about the evolution of these massive Jupiter-like planets closely orbiting their host stars. As Prof. Sarah Millholland explains: “This system highlights how incredibly diverse exoplanets can be. They are mysterious other worlds that can have wild orbits that tell a story of how they got that way and where they’re going.”
MIT researchers have discovered how propofol, a commonly used anesthetic, works on the brain, reports Francesca Benson for IFL Science. The research studied “the differences between an awake brain and one under anesthesia by looking at the stability of the brain’s activity,” writes Bensen.
MIT scientists have discovered how propofol, a commonly used anesthetic, induces unconsciousness, reports Adam Kovac for Gizmodo. “The new research indicates that [propofol] works by interfering with a brain’s ‘dynamic stability’ – a state where neurons can respond to input, but the brain is able to keep them from getting too excited,” explains Kovac.
A research group led by postdoctoral associate Minde An analyzed China’s greenhouse gas emissions over the past decade, finding a substantial increase thought to be primarily driven by aluminum production, reports Ellen McNally for The Guardian. The researchers, writes McNally, say these levels could be reduced “with technological innovation and incorporation of the aluminum industry into the carbon market, or a national carbon trading scheme allowing emitters to buy or sell emission credits.”
Prof. David Rand speaks with New York Times reporters Tiffany Hsu and Stuart A. Thompson about the challenges of stopping the spread of misinformation. “It seems like an easy enough problem: there’s the true stuff and there’s the false stuff, and if the platforms cared about it, they would just get rid of the false stuff,” says Rand. “Then we started working on it and it was like, ‘Oh God.’ It’s actually way more complicated.”
Prof. Kerry Emanuel speaks with New York Times reporter Christopher Kuo about the expectations for the upcoming hurricane season. When discussing Hurricane Beryl, Emanuel says “usually the June and July storms are relatively benign. They don’t get up to full strength, so it’s very rare to have this.”
Prof. Larry Gurth and University of Oxford Prof. James Maynard have uncovered a new finding “about how certain polynomials are formed and how they reach out into the number line,” reports Caroline Delbert for Popular Mechanics. Gurth and Maynard “claim they’ve proven [Dirichlet] polynomials have a certain number of large values, or solutions, within a tighter ranger than before.”
Prof. Kerry Emanuel speaks with Scientific American reporter Chelsea Harvey about the future of hurricane forecasting and preparations. “I can’t predict the future, but I’m optimistic that things will get better,” says Emanuel. “And you’ll see people moving away from risky places, which is already beginning to happen. And those who elect to stay [will be] paying a lot of insurance or retrofitting houses to be built stronger.”
Prof. Emerita Mary-Lou Pardue, a cellular and molecular biologist whose work “formed the foundation for key advancements and discoveries in understanding the structure of chromosomes,” has died at age 90, reports Bryan Marquard for The Boston Globe. Pardue “was a role model of what women in science can be at a time when there weren’t a lot of those, and a trailblazer as a woman,” emphasizes Ky Lowenhaupt, manager of the Biophysical Instrumentation Facility at MIT, “but also a trailblazer as a scientist who didn’t do things along the path that other people took.”
MIT scientists studying parrots have discovered higher intelligence than previously thought, with some birds besting five-year-old children at logic games. With a tablet computer, parrots “have even figured out how to communicate using modern video conferencing technology,” writes Mack DeGeurin for Popular Science. When shown pictures of other parrots they had previously chatted with, “the parrots repeatedly requested to chat with their long-distance friends.”
Prof. Moungi Bawendi, a recipient of the 2023 Nobel Prize in Chemistry, speaks with Nobel Prize Conversations host Adam Smith about the joys of visualizing quantum mechanics, the inspiration for his Nobel-prize winning work and his love of music. “Being in a place like MIT and being exposed to engineering and other scientific fields and medicine across the river and Harvard Medical School and a lot of startups around here, you really are exposed to so many things that are so interesting and I love that,” says Bawendi. “Those things give me ideas of how to go back to the lab and take different directions.”
MIT scientists have created a high-resolution brain map of the neurons that encode the meanings of various words, reports Sara Reardon for Nature. “The results hint that, across individuals, the brain uses the same standard categories to classify words,” Reardon explains, “helping us to turn sound into sense.”
