Prof. Long Ju and his colleagues observed the fractional quantum anomalous Hall effect (FQAHE) when five layers of graphene were sandwiched between sheets of boron nitride, reports Dan Garisto for Nature. The findings are, “capturing physicists’ imagination because they are fundamentally new discoveries about how electrons behave,” writes Garisto.
Senior Research Scientist Lisa Barsotti speaks with MIT Technology Review reporter Sophia Chen about how she and her colleagues developed a new device that uses quantum squeezing to help the LIGO detectors identify more celestial events, such as black hole mergers and neutron star collisions. “With these latest squeezing innovations, installed last year, the collaboration expects to detect gravitational waves up to 65% more frequently than before,” Chen explains.
MIT researchers have developed a new technique “that could allow most large language models (LLMs) like ChatGPT to retain memory and boost performance,” reports Tony Ho Tran for the Daily Beast. “The process is called StreamingLLM and it allows for chatbots to perform optimally even after a conversation goes on for more than 4 million words,” explains Tran.
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.
Writing for Bloomberg, Prof. Carlo Ratti and Arianna Salazar-Miranda SM '16, PhD '23 explore the possibility and potential of developing 15-minute cities in America. “If implemented correctly, the 15-minute city can be an agent of freedom: freedom from traffic jams, freedom to live in a healthy environment and freedom to be outside,” they write. “It is not a one-size-fits-all solution, but our research shows that almost every community in America could benefit from a few more well-placed amenities.”
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 developed an AI model that is capable of identifying 3 ½ times more people who are at high-risk for developing pancreatic cancer than current standards, reports Felice J. Freyer for The Boston Globe. “This work has the potential to enlarge the group of pancreatic cancer patients who can benefit from screening from 10 percent to 35 percent,” explains Freyer. “The group hopes its model will eventually help detect risk of other hard-to-find cancers, like ovarian.”
Javier Ramos '12, SM '14, co-founder of InkBit, and his colleagues have developed a, “3D inkjet printer that uses contact-free computer vision feedback to print hybrid objects with a broad range of new functional chemistries,” reports Ed Brown for Tech Briefs. “Our vision for Inkbit is to reshape how the world thinks about production, from design to execution and make our technology readily available,” says Ramos. “The big opportunity with 3D printing is how to disrupt the world of manufacturing — that’s what we're focused on.”
Scientific American reporter Payal Dhar spotlights how MIT engineers developed a beating, biorobotic replica of the human heart that could be used to “simulate the workings of both a healthy organ and a diseased one.” The replica, "which pumps a clear fluid instead of blood, is hooked up to instruments that measure blood flow, blood pressure, and more," writes Dhar. "It’s also customizable: the user can change the heart rate, blood pressure and other parameters, then watch how these changes affect the heart’s function in real time.”
Smithsonian Magazine reporter Sarah Kuta spotlights MIT researchers and their work in developing an ingestible vibrating pill that simulates the feeling of being full. The device “could someday offer an obesity treatment that doesn’t rely on standard medications or surgery,” writes Kuta.
MIT researchers have created a vibrating capsule that can send signals to the brain to simulate the sensation of being full, reports Brian Heater for TechCrunch. “The capsule, which is roughly the size of a standard multi-vitamin, contains a vibrating motor, powered by a silver oxide battery,” explains Heater. “After reaching the stomach, gastric acid dissolves the outside layer and completes the circuit, kickstarting the vibration.”
Researchers at MIT have developed a vibrating pill that “significantly reduces food consumption by mimicking the feeling of fullness,” reports Arianna Johnson for Forbes. Researchers believe, “the pill can be used as a cheaper, noninvasive option to treat obesity and other weight-related illnesses,” writes Johnson.
MIT researchers have created “a vibrating pill that stimulates nerve endings in the stomach to tell the brain it’s time to stop eating,” reports Mitch Leslie for Science. “A gel plug in the pill keeps the motor from switching on,” explains Leslie. “But the gel dissolves rapidly when it contacts stomach fluid, allowing the motor to start turning. When that happens, the pill shakes for about 38 minutes, roughly the amount of time it would stay in the stomach. The researchers hypothesized that these vibrations would stimulate the stretch-sensing nerve endings and signal satiety.”
