Prof. Julien de Wit speaks with National Geographic reporter Robin George Andrews about how special infrared filters on the James Webb Space Telescope (JWST) can be used to find small asteroids and precisely determine their size. “Asteroids get much brighter in the infrared than in the visible as they move away from Earth, and they are thus easier to detect or track with infrared facilities—JWST being the biggest of all,” says de Wit.
MIT physicists have measured kinetic inductance for two layers of stacked and twisted graphene and found that the superconducting current is much “stiffer,” meaning it resists change more than predicted by any conventional theory of superconductivity, reports Karmela Padavic-Callaghan for New Scientist. The findings could do more than “shed light on why graphene superconducts – they could also reveal key properties required for room-temperature superconductors.”
Evan Ehrenberg PhD '16 co-founded Waterlily, a company that “uses artificial intelligence to predict a family’s future long-term care needs and costs” with the right care and financial planning, reports Mary Ann Azevedo for TechCrunch. “Ehrenberg — who had previously founded and sold Clara Health — helped with early research and was struck by the industry’s response,” writes Azevedo. “Curious, he tested the platform and was shocked by his long-term care predictions — so much so that he changed his diet, hired a personal trainer, and updated his financial plans.”
Prof. Taylor Perron speaks with USA Today reporter Kate S. Petersen about the evidence that humans are changing the Earth’s climate. "What's alarmingly different about the global warming happening now is how fast it's happening and how it's clearly associated with humans adding greenhouse gases like carbon dioxide to the atmosphere," says Perron. "Rapid warming in the geologic past, long before there were humans, led to mass extinctions. And times when it was only slightly warmer than now, like before the last ice age, had sea levels high enough to flood most of today's coastal cities."
MIT astronomers have analyzed the scintillation – or glistening - produced by a fast radio burst (FRB) to help identify the location of the pulses, reports Ashley Strickland for CNN. “We discovered that this FRB exhibits ‘twinkling,’ similar to how stars appear to twinkle in the night sky,” explains postdoc Kenzie Nimmo. “Observing this scintillation indicates that the region where the FRB originated must be incredibly small.”
Researchers from MIT and elsewhere have developed a new vaccine that “could be potentially used against a broad array of coronaviruses like the one that causes Covid-19 and potentially forestall future pandemics,” reports Alex Knapp for Forbes. “The vaccine involves attaching tiny pieces of virus that remain unchanged across related strains to a nanoparticle,” explains Knapp.
In a letter to the editor of The Boston Globe, Vice President for Research Ian Waitz addresses the importance of research staff at the Institute, noting that “research universities educate through research.” Waitz emphasizes: “At MIT, there has been double-digit real growth in our on-campus research enterprise over the past 11 years along with growth in our graduate student body. With that come more people, and while these staff may not be directly involved in student classroom instruction, the research they conduct is crucial to the hands-on education that MIT students receive and to the real-world solutions that originate at the school.”
MIT engineers have developed “two new control techniques that have enabled them to achieve a world-record single-qubit fidelity of 99.998 percent using a superconducting qubit called fluxonium,” reports Aman Tripathi for Interesting Engineering. “This breakthrough marks a significant step towards the realization of practical quantum computing,” Tripathi notes.
USA Today reporter Eric Lagatta writes that a new study by MIT researchers finds that X-ray flashes emanating from a supermassive black hole located 270 million light-years from the Milky Way could be caused by a dead stellar remnant, or white dwarf. The researchers believe that the white dwarf could be “spinning precariously on the edge of the black hole, causing the explosions of high-energy light.”
MIT astronomers have detected X-ray flashes erupting from a supermassive black hole that seem to be caused by a nearby white dwarf, reports Will Dunham for Reuters. “It is probably the closest object we've ever observed orbiting around a supermassive black hole,” says graduate student Megan Masterson. “This is extremely close to the black hole's event horizon.”
MIT astronomers have witnessed flashes of X-rays shooting out of a black hole and believe that a dead star, or white dwarf, passing close by the black hole could be causing the eruptions, reports Mark Kaufman for Mashable. “The astronomers ran simulations of what could drive these unusual bursts of energy,” writes Kaufman. “The most plausible outcome is this brazen white dwarf (the spent core of a sun-like star), which is about one-tenth the mass of our sun. It's shedding its dense, outer layer and triggering these pulses of X-rays.”
Space.com reporter Robert Lea writes that using the XMM-Newton X-ray telescope, MIT astronomers have observed bursts of X-rays erupting with increasing frequency from a supermassive black hole, a behavior they think could be caused by a “dead stellar core, or white dwarf, daringly teetering on the edge of the black hole.” Lea explains that “if the source of these strange episodes is a finely balanced white dwarf, the researchers theorize that it could be detected using ripples in space and time called gravitational waves emitted from the system.”
Quanta Magazine reporter Charlie Wood spotlights how MIT researchers have contributed to the recent discoveries of new superconductive materials. Prof. Long Ju and his research team “placed a five-layer graphene flake on an insulator at a twisted angle and observed a rare electron behavior that normally requires a strong magnetic field to induce,” explains Wood.
MIT Profs. Angela Belcher, Emery Brown, Paula Hammond and Feng Zhang have been honored with National Medals of Science and Technology, reports Michael T. Neitzel for Forbes. Additionally, R. Lawrence Edwards '76 received a National Medal of Science and Noubar Afeyan PhD '87, a member of the MIT Corporation, accepted a National Medal on behalf of Moderna. The recipients have been awarded “the nation’s highest honors for exemplary achievements and leadership in science and technology,” explains Neitzel.
Prof. Anna Frebel spotlights the work of Cecilia Payne, whose research “laid the foundation of stellar astrophysics,” reports Liz Kruesi for National Geographic. “It is such a fundamental piece of understanding for humanity,” says Frebel of the importance of Payne’s work discovering that stars are mainly made up of hydrogen and helium
