UPI reporter Brooks Hays writes that MIT researchers have discovered an extended dark matter halo encircling an ancient dwarf galaxy about 163,000 light years from Earth. “The findings suggest many more of the cosmos' earliest galaxies may have formed within expansive dark matter halos,” writes Hays.
Andrea Ghez ’87 speaks with Carol Stabile of Ms. magazine about the importance of representation in encouraging more women and people of color to pursue careers in STEM fields. Ghez recalls how her science teacher in high school encouraged her to apply to MIT, describing the experience as “'a lovely early lesson in how to persevere,’ that helped her to develop what she described as the muscle to persevere, and to turn problems into opportunities to grow and learn.”
A series of papers by MIT researchers demonstrates how their design for a new nuclear fusion reactor should work, reports Oscar Schwartz for The Guardian. “Fusion seems like one of the possible solutions to get ourselves out of our impending climate disaster,” says Martin Greenwald, deputy director of MIT’s Plasma Science and Fusion Center.
Writing for The Boston Globe, Prof. Ernest Moniz, the former U.S. Secretary of Energy, underscores the importance of addressing climate change. Moniz calls for providing “as many options and as much flexibility as possible to meet the deep decarbonization goal — and innovation is key. We need as many low- to no-carbon tools as can be developed. This inclusive approach is what will get us to a shared goal of climate risk mitigation the fastest.”
MIT researchers have developed a new atomic clock that can keep time more precisely thanks to the use of entangled atoms, reports Leila Stein for Popular Mechanics. “If all atomic clocks worked the way this one does then their timing, over the entire age of the universe, would be less than 100 milliseconds off,” Stein writes.
Physics World selected a study by researchers from MIT’s LIGO Lab that shows quantum fluctuations can jiggle objects as large as the mirrors of the LIGO observatory as one of the top 10 breakthroughs of the year. “The research could lead to the improved detection of gravitational waves by LIGO, Virgo and future observatories,” notes Hamish Johnston for Physics World.
Symmetry Magazine reporter Sarah Charley writes that a new study co-authored by MIT postdoc Xiaojun Yao examines how quantum computing could advance our understanding of quantum processes. Yao explored how “the properties of a heavy particle could be impacted after it traversed through a quark-gluon plasma,” and after several months of testing was able to “demonstrate that these kinds of calculations are already feasible on today’s quantum computers.”
Writing for Popular Mechanics, Leila Stein highlights how MIT researchers have created a perfect fluid and captured its sound. “To record the sound, the team of physicists sent a glissando of sound waves through a controlled gas of elementary particles called fermions,” Stein writes.
Prof. Martin Zwierlein speaks with Edgar Herwick III of GBH Radio about his work capturing the sound of a “perfect” fluid. "It was a beautiful sound," says Zwierlein. "It was a quantum sound. In a way it was the most long-lasting sound that you can imagine given the laws of quantum mechanics.”
New Scientist reporter Abigail Beall spotlights how MIT researchers have listened to sound waves traveling through a "perfect" fluid, which could shed light on the resonant frequencies within a neutron star. “The quality of the resonances tells me about the fluid’s viscosity, or sound diffusivity,” says Prof. Martin Zwierlein. “If a fluid has low viscosity, it can build up a very strong sound wave and be very loud, if hit at just the right frequency. If it’s a very viscous fluid, then it doesn’t have any good resonances.”
Prof. Martin Zwierlein speaks with Madeline Sofia and Emily Kwong of NPR’s Short Wave about his work with ultracold quantum gases and observing superfluid states of matter. “Luckily we have techniques to actually take rather beautiful pictures of this quantum soup of these whirlpools of individual atoms,” says Zwierlein, “to try and make it out of this invisible realm and make it very real, touchable.”
MIT seniors Danielle Grey-Stewart and Ghadah Alshalan have been selected for the 2021 Rhodes Scholarship program, reports Gal Tziperman Lotan for The Boston Globe.
Research scientist Clara Sousa-Silva speaks with Wired reporter Abigail Beall about phosphine, a molecule that she has spent the past decade investigating. “Phosphine is a horrific molecule, it’s foul in every way,” she says. “It’s almost immoral, if a molecule can be.”
Writing for Science, Charlie Greenwood spotlights how MIT researchers are building upon their pioneering work twisting sheets of graphene together to create superconductors by using twisted graphene to develop working devices. “Many researchers are excited by the promise of exploring electronic devices without worrying about the constraints of chemistry,” writes Greenwood.
A team of astronomers, including MIT researchers, have identified fast radio burst emanating from a magnetar in our galaxy, reports Doyle Rice for USA Today. “The radio pulses are the closest ones detected to date, and their proximity has allowed the team to pinpoint their source.”
