Prof. Benjamin Weiss speaks with CNN reporter Ashley Strickland about how the Perseverance rover will select samples of Martian materials. "The key for this mission will be identifying samples so compelling that we can't afford to leave them," says Weiss. "We are selecting these for humanity, so we need to make sure they are the most exciting."
A study by MIT researchers uncovers evidence that the Earth’s global ice ages were triggered by a rapid drop in sunlight, reports Mashable. The researchers found that an “event like volcanic eruptions or biologically induced cloud formation will be able to block out the sun and limit the solar radiation reaching the surface at a critical rate that can potentially trigger ‘Snowball Earth’ events.”
Michael Hecht of MIT’s Haystack Observatory speaks with Perry Russom of NECN about MOXIE, a new experimental device that will convert carbon dioxide in the Marian atmosphere into oxygen. Hecht explains that the inspiration for MOXIE lies in how it would be easier, “if we could make that oxygen on Mars and not have to bring this huge honking oxygen tank with us all the way from Earth.”
Prof. Tanja Bosak speaks with Vox reporter Brian Resnick about how Martian materials collected by the Perseverance rover might provide clues about early life forms on Earth. "These [Martian] rocks are older, by half a billion or a billion years, than anything that’s well preserved that we have on Earth,” says Bosak.
Boston Globe reporter Caroline Enos spotlights the contributions of MIT researchers to the Mars 2020 mission, in particular the Mars Oxygen In-Situ Resource Utilization Experiment or MOXIE. “MOXIE could have a big impact on future missions if it is successful,” Enos explains.
Haystack’s Michael Hecht, the principal investigator for the Mars MOXIE experiment, speaks with Max G. Levy of Smithsonian about the challenges involved in developing MOXIE’s oxygen-producing technology. “We want to show we can run [MOXIE] in the daytime, and the nighttime, in the winter, and in the summer, and when it’s dusty out," says Hecht, "in all of the different environments."
Forbes contributor Bruce Dominey writes that a study by MIT researchers finds global ice ages may have been triggered by a rapid decrease in the amount of solar radiation reaching Earth. “Past Snowball glaciations are more likely to have been triggered by changes in effective solar radiation than by changes in the carbon cycle,” writes Dominey.
Prof. Tanja Bosak speaks with Verge reporter Loren Grush about the significance of the Mars 2020 mission and the Perseverance rover’s quest to bring back samples of Martian material to Earth. “This is really a unique — really a once-in-a-lifetime — opportunity to get samples from a known location on Mars,” says Bosak.
Quanta Magazine reporter Thomas Lewton writes that a new study co-authored by Prof. Frank Wilczek explores how gravitons may create “noise” that could be identified by gravitational wave detectors. “There’s a kind of default consensus that it’s a waste of time to think about quantum effects and gravitational radiation,” said Wilczek. “There’s nothing like actual experimental results to focus the attention.”
Gizmodo reporter George Dvorsky writes about how researchers from MIT and other institutions have detected the corona of a supermassive black hole disappearing and then reappearing. Dvorsky writes that their findings suggest this “strange episode was caused by a runaway star.”
Prof. Max Tegmark speaks with Richard Webb at New Scientist about shifting his focus from cosmology to “intelligence, both human and artificial.” “It was very natural for me to gravitate to the biggest unsolved mystery that’s sort of coming within range,” says Tegmark. “We are able to see things with telescopes that our ancestors could never see, and the same thing is happening now with the mind.”
Writing for The Washington Post, Prof. Harvey Lodish emphasizes the importance of foreign workers and immigrants to the U.S. economy. “Without students and workers from outside the U.S., it’s difficult to see how the current successes of U.S. scientific research and innovation could continue,” writes Lodish.
TechCrunch reporter Darrell Etherington writes that CSAIL researchers have built a new two-fingered robotic gripper. The researchers “equipped their robotic gripper with fingertips that are not only made out of a soft material, but that also have embedded sensors which help it continually detect the position of a cable between the grippers to better control holding and manipulating them while performing simple tasks like detangling.”
WBUR’s Carey Goldberg explores how MIT researchers developed a new CRISPR-based research tool that can be used to detect Covid-19. "A lot of things that we try fail," says research scientist Jonathan Gootenberg. "And that’s OK. Because sometimes you find these things that are really, really awesome."
A new study by MIT researchers explores how cellular guides in planarians appear to provide a roadmap for regeneration, reports Veronique Greenwood for The New York Times. Greenwood notes that the findings “may someday help scientists interested in helping humans regenerate injured neurons.”
