MIT researchers have made improvements to liquid-sodium batteries, potentially paving the way for the battery to be used for renewable energy storage, reports Laney Ruckstuhl for The Boston Globe. “Unlike lithium-ion batteries used in cellphones and laptops, the liquid-sodium batteries won’t lose their capacity quickly.”
In an article for Physics Today, Prof. Anna Frebel details the formation of the heaviest elements. While scientists previously thought that supernova explosions were responsible for the creation of elements heavier than iron, Frebel notes that evidence from LIGO and from a faint galaxy known as Reticulum II suggest, “neutron-star mergers are the universe’s way to make elements such as gold and platinum.”
Boston Globe reporter Marin Finucane writes that with the help of around 10,000 citizen scientists, a team of astronomers has discovered five planets outside our solar system. “It’s exciting because we’re getting the public excited about science, and it’s really leveraging the power of the human cloud,” says Prof. Ian Crossfield of the discovery.
Prof. Emeritus Rainer Weiss has been named to The Boston Globe’s list of the 2017 Bostonians of the Year for his work starting a new revolution in astronomy. Globe reporter Eric Moskowitz notes that Weiss, “shared the Nobel Prize for Physics for conceiving and shepherding a set of observatories that allowed scientists to prove Einstein’s assertion about gravitational waves.”
The discovery of the oldest and most distant black hole ever detected has provided a team of astronomers new insights into our universe, writes Alyssa Meyers for The Boston Globe. “In some sense, what we’ve done is determine with a high degree of accuracy when the first stars in the universe turned on,” explains Prof. Robert Simcoe.
The discovery of the oldest and most distant black hole ever observed could provide scientists with insights into the early stages of our universe, reports Will Dunham for Reuters. “This object provides us with a measurement of the time at which the universe first became illuminated with starlight,” explains Prof. Robert Simcoe.
NPR’s Nell Greenfieldboyce reports that scientists have discovered the most distant supermassive black hole every discovered, and that the findings are shedding light on when starlight first appeared in our universe. "We have an estimate now, with about 1 to 2 percent accuracy, for the moment at which starlight first illuminated the universe,” explains Prof. Robert Simcoe.
USA Today reporter Doyle Rice writes that a team of astronomers, including several from MIT, has discovered the oldest and most distant supermassive black hole ever detected. “The black hole resides in a quasar and its light reaches us from when the universe was only 5% of its current age — over 13 billion years ago,” explains Rice.
Newsweek reporter Katherine Hignett writes that MIT and Harvard researchers have successfully manipulated individual atoms using lasers in one of the largest quantum computer simulations. Hignett writes that, “their technology could help make superfast quantum computers a working reality.”
Boston Globe reporter Alyssa Meyers writes that researchers from MIT and Harvard have demonstrated one of the largest quantum simulators that can trap individual atoms in laser beams. Prof. Vladan Vuletić explains that it is, “a major advance is to be able to align and arrange individual atoms so we can hold on to them and track them.”
Prof. Nergis Mavalvala speaks with Massive reporter Prabarna Ganguly about her work engineering high-precision laser beams to detect signals from deep space, the long hunt for gravitational waves and her hopes for future generations of scientists. Ganguly writes that Mavalvala is, “one of the stalwarts in a long, arduous, and deeply human discovery of faraway perturbations rippling through the universe.”
Los Angeles Times reporter Amina Khan writes that researchers from the LIGO Scientific Collaboration have identified gravitational waves emitted from the smallest black hole they have detected. “Its mass makes it very interesting,” explains Prof. Salvatore Vitale. The discovery, he adds, “really starts populating more of this low-mass region that [until now] was quite empty.”
The late Institute Prof. Emerita Mildred Dresselhaus is featured on MSNBC Live with Velshi & Ruhle’s “Monumental Americans” series, which highlights Americans they believe should be honored with a statue. “Known as ‘the Queen of Carbon Science,’ the electrical engineer worked at MIT for 57 years and was a pioneer for women in science leadership positions.”
UPI reporter Brooks Hays writes that an international team of astronomers, including MIT Prof. Saul Rappaport, has detected comets outside the Milky Way. “The distant ice balls, roughly the size of Halley's Comet, were spotted orbiting a small star 800 light-years from Earth. They were documented using transit photometry,” Hays explains.
MIT research scientist John Wright speaks with Hannah Osborne of Newsweek about a new process developed to heat fusion plasma, raising ions to energy levels greater than previously achieved. Wright explains that, “this method may have applications to more efficient heating of the plasma to the temperatures needed to begin the fusion burn.”
