Research led by Dheeraj Pasham, a postdoc at MIT's Kavli Institute, provides evidence “that black holes feed on passing stars then eject energetic jet streams,” writes Laney Ruckstuhl for The Boston Globe. “Such black hole jet streams can have large implications for the galaxies they enter. Pasham said they can regulate the growth of a galaxy because of their energy levels."
For his blog “In the Pipeline”, Science writer Derek Lowe discusses the potentials of graphene as a superconductor, highlighting research led by associate Prof. Pablo Jarillo-Herrero. He goes on to mention the same technology as enabling MIT’s “tokamak-design fusion reactor that is far more compact than any previous attempts.”
BBC News reports on the creation of Kagome metal, an “electrically conducting crystal, made from layers of iron and tin atoms,” that could be used in more powerful quantum computers. The shape of the conductor, developed by Assistant Professor Joseph Checkelsky and graduate student Linda Ye, mimics a popular pattern in Japanese basket-weaving.
NPR’s Jason Beaubien speaks with Broad Institute Associate Director Nathan Yozwiak about the current outbreak of the Lassa virus in Nigeria. "What we could be seeing rather than an emerging disease is an emerging diagnosis,” said Yozwiak, explaining that the recent uptick could actually stem from increased awareness and reporting.
Brooks Hays for UPI highlights research led by postdoc Dheeraj Pasham from MIT's Kavli Institute, that has captured the rare occurrence of “radio signals produced by a black hole devouring a star.” “This is the first time we've seen a jet that's controlled by a feeding supermassive black hole,” explained Pasham.
Researchers from the Media Lab and Sloan found that humans are more likely than bots to be “responsible for the spread of fake news,” writes Paul Chadwick for The Guardian. “More openness by the social media giants and greater collaboration by them with suitably qualified partners in tackling the problem of fake news is essential.”
In an op-ed for The Washington Post, Megan McArdle shares her thoughts on research from the Media Lab and Sloan that identifies “fake news” as traveling six times faster than factual news. “The difference between social media and ‘the media’ is that the gatekeeper model…does care more about the truth than ‘the narrative,’” McArdle writes.
Jordan Webber of The Guardian addresses the rise of “fake news”, citing research from the Media Lab and Sloan. “I believe that social media is a turning point in human communication,” said Sloan Prof. Sinan Aral. “I believe it is having dramatic effect on our democracies, our politics, even our health.”
Researchers have developed a microfluidic platform called “physiome on a chip”, which allows them to determine how certain drugs will affect up to 10 different organs. “Because the animal and human immune systems are different, [drug] testing is difficult in non-human trials,” writes Allen Cone for UPI, “but [this] system could help with that.”
Prof. Alan Lightman celebrates the life of Stephen Hawking in this opinion piece for The Washington Post. “The passing of Stephen Hawking gives us the opportunity to celebrate the best in ourselves, to reaffirm the power of the human mind and the majesty of our desire to know and to understand this strange universe we find ourselves in.”
Prof. Linda Griffith has created a “complex platform where researchers can put up to 10 organ tissues in separate compartments, regulating the flow of substances and medications between them in real time,” to determine how each organ will react, writes Devin Coldewey for TechCrunch. The scale of this model “represents a huge jump in the capabilities of this kind of system.”
Prof. Linda Griffith has developed ten miniature models of human organs “to create the closest we’ve come yet to a human-on-a-chip,” writes Jessica Hamzelou for New Scientist. “This is still only a minimal representation of a human,” said Griffith, but this kind of system could eventually eliminate the need for animal testing.
New research from visiting scientist Judah Cohen suggests that “severe winter weather in the United States is often tied to (relatively) high heat in the North Pole,” writes Eleanor Cummins for Popular Science. “If the Arctic is cold, that favors less severe winter in the eastern U.S.,”said Cohen. “When the Arctic is warm, it’s the opposite relationship.”
Matt Simon of Wired describes research led by visiting scientist Judah Cohen, which used the “Accumulated Winter Season Severity Index”, to reveal that warming in the arctic is associated with severe winter weather conditions. “[The researchers] looked at peaks in arctic temperatures and found that these anticipated severe weather by five days, which would suggest a link,” Simon writes.
A study from senior researcher Rolland Pellenq finds that grid-like cities retain more heat than those that are less-linear, due to the “Urban Heat Island” effect. “For new cities, or even neighborhoods, our findings can be used…in designing block layouts that would help optimize temperature,” Pellenq explains to Marlene Cimons of Popular Science.
