Gizmodo reporter Isaac Schultz writes that MIT scientists have captured images of heat moving through a superfluid, a phenomenon that “may explain how heat moves through certain rare materials on Earth and deep in space.” Schultz notes that the researchers believe their examination of heat flow in a superfluid “can be used to determine heat flow in high-temperature superconductors, or even in neutron stars, the roiling, ultra-dense relics of ordinary stars.”
For the first time, MIT physicists have successfully imaged how heat travels in a superfluid, known as a “second sound,” reports Darren Orf for Popular Mechanics. “While exotic superfluids may not fill up our lives (yet),” writes Orf, “understanding the properties of second wave movement could help questions regarding high-temperature superconductors (again, still at very low temperatures) or the messy physics that lie at the heart of neutron stars.”
Physics World reporter Tim Wogan spotlights how MIT physicists have developed a new technique for measuring the temperature of “second sound,” the movement of heat through a superfluid. “The work could help model a variety of scientifically interesting and poorly understood systems, including high temperature superconductors and neutron stars,” Wogan explains.
Prof. Ernest Moniz and his colleagues have designed a new consortium that plans to create an organized market for hydrogen, reports Llewellyn King for Forbes. This will allow hydrogen to become “a viable option in the pursuit of net-zero emissions,” writes King.
Prof. Erin Kara speaks with Quanta Magazine reporter Michael Greshko about her career as an observational astrophysicist and her work to better understand how black holes behave and reshape galaxies across the universe. “The thing that really got me excited about pursuing astronomy was the discovery aspect: It was just super thrilling to be the first person to look at light that was released from around a black hole a billion years ago,” says Kara.
Senior Lecturer Richard Price and his colleagues have scored a touchdown by uncovering the physics behind a spiral pass, “those perfect throws where the football leaves the player's hand and neatly spins as it arcs through the air,” reports NPR Short Wave host Regina Barber.
A more than $40 million investment to add advanced nano-fabrication equipment and capabilities to MIT.nano will significantly expand the center’s nanofabrication capabilities, reports Jon Chesto for The Boston Globe. The new equipment, which will also be available to scientists outside MIT, will allow “startups and students access to wafer-making equipment used by larger companies. These tools will allow its researchers to make prototypes of an array of microelectronic devices.”
MIT researchers have discovered 18 new tidal disruption events (TDEs), “which are huge bursts of energy released as a star is shredded by a black hole,” reports Jess Thomson for Newsweek. “These new discoveries have also helped scientists learn more about what TDEs really are and where they occur,” explains Thomson. “The previous stock of TDEs had only been found in a rare form of galaxy known as a ‘post-starburst’ system, which once created a number of stars but has since stopped.”
MIT researchers have discovered that “stars at the edge of our home galaxy appear to be moving more slowly than expected,” reports Jess Thomson. This discovery “implies that the galaxy itself may be structured differently from how scientists first thought, with the core of the Milky Way possibly containing less dark matter and, therefore, being lighter in mass than first assumed,” explains Thomson.
Researchers from MIT and elsewhere have proposed a new method to look for primordial black holes (PMBs), reports Jackie Appel for Popular Mechanics. “If there are as many as the team thinks there should be, and they interact with gravity as we expect them to, they should be zooming around in a way that some of them should pass close by various objects in our solar system – including Earth,” explains Appel. “And if that happens, it should actually be enough to disturb the natural orbits of these objects in a way that we can measure.”
Researchers from MIT and elsewhere have uncovered “a major advancement in the development of ‘error correction,’ the process of fighting the subatomic deterioration that makes most quantum computers today unhelpful for more than research purposes,” reports Derek Robertson for Politico.
Researchers from MIT and elsewhere have successfully linked together two molecules in special quantum states, reports Pandora Dewan for Newsweek. “The discovery may lead to more robust quantum computing and support new research techniques,” writes Dewan.
Prof. Nergis Mavalvala, dean of the School of Science, speaks with Wired reporter Swapna Krishna about her work searching for gravitational waves, the importance of skepticism in scientific research and why she enjoys working with young people. Mavalvala explains, “there’s an idea that the greatest scientific discoveries are made by wiry silver-haired scientists. But it’s the work of young people that enables all of these scientific discoveries.”
Prof. Sara Seager and her colleagues have discovered “a six-pack of planets, formed at least 4 billion years ago,” that orbit a nearby sun-like star named HD110067, reports Joel Achenbach for The Washington Post. “Occasionally, nature reveals an absolute gem,” says Seager. “HD 110067 is an immediate astronomical Rosetta stone – offering a key system to help unlock some mysteries of planet formation and evolution.”
MIT researchers have successfully figured out how to trap tiny electrons in a three-dimensional crystal prison, reports Jess Thomson for Newsweek. The researchers hope that “the flat band properties of the electrons in these crystals will help them to explore new quantum states in three-dimensional materials,” Thomson explains, “and therefore develop technology like superconductors, supercomputing quantum bits, and ultraefficient power lines.”
