MIT researchers have found that the universe’s first stars exploded in an aspherical manner, spewing heavy metals into the universe, reports Rachel Cromwell for Scientific American. “This is a beautiful paper,” says Volker Bromm of the University of Texas at Austin, noting that this type of stellar sleuthing is possible only with very high-quality data.
National Geographic reporter Michael Greshko writes about a new effort by researchers from a number of institutions, including MIT, to reassess the possibility of cold fusion. Prof. Yet-Ming Chiang explains that he hopes to be able to create a “‘reference experiment’ for other labs to also advance research into lower-energy nuclear physics.”
MIT alumnus Murray Gell-Mann, a pioneering physicist who “helped make sense of the very small,” died at the age of 89, reports George Dvorsky for Gizmodo. Dvorsky writes that Gell-Mann will be remembered for “bringing order to the chaotic field of particle physics, and for coining the term ‘quark.’”
The Associated Press memorializes the life and work of Murray Gell-Mann, an MIT alumnus who “transformed physics by devising a method for sorting subatomic particles into simple groups of eight.”
MIT alumnus Murray Gell-Mann, a Nobel laureate known for his work conceiving the idea of quarks, died on May 24, reports Martin Weil for The Washington Post. Gell-Mann, who earned a doctorate in physics at MIT, was a “pioneer in the development of what is called the ‘standard model’ of particle physics, a guide to the fundamental behavior of the constituents of the universe.”
Prof. Wolfgang Ketterle speaks with Bloomberg columnist Faye Flam about the recently redefined standard of measurement for the kilogram and the importance of making the change understandable to the general public. “Not everyone is explaining the new kilogram as a quantity of light, but MIT physicist Wolfgang Ketterle makes a convincing case that this is the best and simplest way to understand it,” writes Flam.
WGBH's Edgar Herwick reports on Prof. Wolfgang Ketterle’s presentation exploring the kilogram’s new standard of measurement. Ketterle explained that the change will have a big impact, in particular for micro and nanotechnologies. "Small quantities matter for our lives," said Ketterle.
Inside Higher Ed reporter Lindsay McKenzie writes that a new AI system developed by MIT researchers to summarize the findings of technical scientific papers could “be used in the near future to tackle a long-standing problem for scientists -- how to keep up with the latest research.”
Newsweek reporter Aristos Georgiou writes that MIT researchers have found that explosions of our universe’s first stars sent the first heavy elements into neighboring galaxies. “These elements provided the raw material for the formation of a second generation of stars, some of which survive to this day,” Georgiou explains.
Sky and Telescope editor Monica Young speaks with WBUR about how scientists from the LIGO and Virgo gravitational wave observatories, including MIT researchers, may have detected a black hole colliding with a neutron star. Young explains that upgrades made to both observatories should enable investigation of not only individual cosmic events, but also the study of neutron stars and black holes as populations.
Adrian Cho of Science magazine writes that the possible black hole-neutron star merger spotted by LIGO and Virgo would be a “gem for scientists,” but work remains to confirm the signal. Prof. Salvatore Vitale, a LIGO member from MIT, tells Cho: “If you ask me, ‘Would you bet a coffee, your car, or your house on this?’ I would say, ‘I’d bet your car.’”
Gizmodo reporter Ryan Mandelbaum explores the five potential gravitational wave detections made by the LIGO and Virgo observatories in the last month. Prof. Salvatore Vitale explained that the possible detection of a black hole colliding with a neutron star could provide scientists with a better way to measure how quickly the universe is expanding.
“LIGO/VIRGO has opened up its notification process to the public,” explains Ars Technica reporter John Zimmer. “In short, anyone who’s interested can find out what LIGO is seeing within a day of when the LIGO scientists themselves do.”
The LIGO and Virgo gravitational wave detectors have identified five new cosmic events since resuming operations last month, reports Sarah Lewin for Space.com. “The most exciting thing of the beginning of O3 [this third observation round] is that it's clear we are going from one event every few months to a few events every month," explains Prof. Salvatore Vitale.
Writing for Quanta Magazine, David Freedman spotlights Prof. Pablo Jarillo-Herrero’s discovery that when twisted to a “magic” angle, graphene can act as a semiconductor. Freedman writes that the “discovery has given scientists a relatively simple platform for exploring exotic quantum effects.”
