MIT researchers have developed a new technique to synthesize the feel-good molecules in the Kava plant root, reports Carey Goldberg for WBUR. “What we do in our lab is to actually start from plants that have thousands of years of use in traditional medicine," says Prof. Jing-Ke Weng. "We already know there's something in that plant that works to treat some illness."
Profs. Daniel Rothman and Daniela Rus contributed to a Boston Globe piece exploring what the next big moonshot challenge should be. Rothman noted that, “We need to understand how the Earth system responds to environmental change,” while Rus expressed a desire to explore interspecies communication and the development of intelligent clothing.
A new study by MIT researchers finds that there are differences in how genes are used in men and women, reports Angus Chen for WBUR. “I think we are at present missing a lot because we operate with what is essentially a unisex model in biomedical research,” explains Prof. David Page.
A study by Prof. Dan Rothman finds that increasing greenhouse gas emission rates could trigger a mass extinction in the ocean, reports Priya Shukla for Forbes. Shukla writes that Rothman found if a certain carbon threshold “is breached, it would take tens of thousands of years for the oceans to return to their original unperturbable state.”
MIT researchers have developed artificial muscles that can stretch more than 1,000 percent of their size and lift more than 650 times their weight, reports Sid Perkins for Scientific American. The new fibers could have applications in robotics and prosthetic devices, Perkins explains, and “work more like real muscles: they do work by pulling on or lifting objects.”
Reporting for WBUR, Carey Goldberg highlights how MIT researchers have developed a new RNA editing tool that could be used to tweak a gene that raises the risk of Alzheimer’s disease. As the effects of RNA editing are not permanent, “it's almost like a small, pill-like version of gene therapy,” explains research scientist and McGovern Fellow Omar Abudayyeh.
MIT researchers have developed a new method for potentially increasing solar cell efficiency beyond the theoretical limit, reports Daniel Oberhaus for Wired. “What’s cool here is that this is a fundamentally different approach from traditional photovoltaics,” says Joseph Berry of the National Renewable Energy Laboratory.
A study by Prof. Daniel Rothman finds that if carbon emissions exceed a critical threshold, it could lead to a mass extinction, reports Martin Finucane for The Boston Globe. "We should limit carbon dioxide emissions,” says Rothman. “The carbon cycle is a non-linear system, and if you perturb it, surprising things may happen.”
Axios reporter Eileen Drage O’Reilly highlights how Prof. Feng Zhang and his colleagues have developed a new system that uses “jumping genes” to improve the accuracy of gene editing. “This is filling a gap we couldn't address before, to be able to insert DNA into the genome," says Zhang of the ability to insert large genomes in a directed way.
Researchers from MIT and other institutions have developed a new model for autism research that could enable new therapies and treatments, reports the Xinhua news agency. The model could “provide a basis for a deeper understanding of the neurobiological mechanisms of autism and the development of more transformative therapeutics.”
Boston Globe reporter Martin Finucane writes that a team of scientists, including MIT researchers, has uncovered evidence of a large mass, which could be the metallic core of an asteroid, under a crater on the dark side of the moon. “The results of this study provide new information on the violent history of our nearest celestial neighbor,” explains Prof. Maria Zuber, MIT’s vice president for research.
STAT reporter Sharon Begley writes that Prof. Feng Zhang and his colleagues have turned “a jumping gene — aka a transposon, or mobile genetic element — into a mini TaskRabbit gig worker: With an assist from CRISPR enzymes, it zips over to the part of the genome whose address it is given and delivers a package of DNA, pronto.”
On Science Friday, Prof. David Kaiser speaks with Ira Flatow and Annie Minoff about Albert Michelson, a physicist who was known for his work trying to detect evidence of the luminiferous ether, the hypothetical matter that for years scientists believed light traveled through.
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.
A new book by graduate student John Urschel chronicles his decision to retire from the NFL and pursue his passion for mathematics at MIT, reports the Associated Press. Urschel explains that through his book, he “wanted to share my love of math and also perhaps train certain peoples’ thinking about math and show them some of the beauty, elegance and importance of mathematics.”
