Nuclear science and engineering

Prof. Emeritus Ernest Moniz – former US Energy Secretary and co-chair of the Nuclear Threat Initiative – speaks with Jeremy Hobson on WBUR’s Here & Now about the Trump-Putin summit and what it could mean for nuclear dialogue.

In this CNBC article, Prof. R. Scott Kemp weighs in on the implications of the agreement signed by President Donald Trump and North Korean leader Kim Jong-un. Kemp writes that, “a realistic agreement will probably take years to hash out, as there is much to learn about North Korea's program first. The Trump-Kim statement of principles is exactly what is needed to get started."

In this opinion piece published by The Boston Globe, Vice President for Research Maria T. Zuber writes that fusion energy is within reach: "The MIT design uses established science for the plasma confinement, and thus puts fusion power plants within reach on a faster time-scale than previously thought possible."

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.”

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.”

Prof. Ernest Moniz, the former Secretary of Energy, appeared on Real Time with Bill Maher to discuss the Iran nuclear deal. Moniz explains that the deal helps to ensure nuclear security as it “puts in place verification measures that are completely unique and apply to this deal forever.” 

Damian Carrington writes for The Guardian that MIT researchers set a new world record for the highest plasma pressure ever recorded using the Alcator C-Mod reactor. Carrington notes that the “MIT record shows that using very high magnetic fields to contain the plasma may be the most promising route to practical nuclear fusion reactors.”

A team of scientists, including MIT researchers, has analyzed the measurements made by the IceCube Neutrino Observatory and found no evidence of the sterile neutrino, a new type of neutrino, reports Brendan Cole for Wired. 

MIT researchers have outlined a new way of developing a lithium-oxygen battery that would increase the battery’s energy efficiency and longevity, according to The Economist. “In trials which discharged and recharged the battery 130 times, it lost less than 2% of its capacity,” The Economist notes. 

Boston Globe reporter Cristela Guerra writes that Profs. Janet Conrad and Lindley Winslow helped ensure the science in the new “Ghostbusters” was as accurate as possible. “I am very fond of the original ‘Ghostbusters’,” says Conrad. “I have even used ‘Ghostbusters’ as a theme for my colloquium on neutrino physics, since neutrinos are often called the ghost particle.”

MIT researchers have developed a new lithium-oxygen battery concept that improves energy efficiency and longevity, and could potentially be used in long-distance electric cars and smartphones, reports Ben Woods for Wired. The new approach results in “faster charging and more efficient batteries, due to lower heat wastage,” Woods explains. 

MIT researchers have found that two types of turbulence within plasma could explain the heat loss that takes place in fusion reactors, reports Thomas Tamblyn for The Huffington Post. “With the mystery solved, researchers can now better understand how the plasma reacts and then in turn start working on fundamental ways to combat it.” 

Prof. Ju Li and graduate students Sangtae Kim and Soon Ju Choi have developed a device that harvests human motion for electrical power, reports Krithika Varagur for The Huffington Post.  “This device will make it possible to harvest some of this otherwise-wasted potential into electricity,” explains Kim. 

Fortune reporter Hilary Brueck writes that MIT researchers have developed a new flexible battery that can harness energy from a range of motions, including walking. Brueck explains that the “bendy battery works best with normal, human-scale activity, like walking, poking, and bending.”

Los Angeles Times reporter Evan Halper speaks with MIT Corporation member and alumna Leslie Dewan, co-founder of Transatomic Power, about nuclear energy and climate change. “I became a nuclear engineer because I am an environmentalist,” said Dewan. “The world needs a cheap source of carbon-free power.”
