The Economist spotlights alumna Lisa Su S.B. ’90, S.M. ’91, PhD ’94, who is the chief executive of the chip maker AMD. “I learned that when I chose something very difficult, and did well, it would give me great confidence for the next challenge,” says Su.
Gizmodo reporter George Dvorsky writes that astronomers have found two red asteroids, which resemble objects typically found beyond Neptune, in the main asteroid belt between Mars and Jupiter. “This finding suggests some asteroids in the main belt formed in the outer solar system, and that a population of these objects is likely to exist within the main belt,” writes Dvorsky.
A study by graduate student Carly Ziegler finds that how cells in the nose respond to the coronavirus could help predict how sick a person might become with Covid-19, reports Nancy Lapid for Reuters. "If further studies support our findings, we could use the same nasal swabs we use to diagnose COVID-19 to identity potentially severe cases before severe disease develops, creating an opportunity for effective early intervention," says Ziegler.
A new study by MIT economists finds that sleeping more may not improve performance or well-being, especially if night-time sleeping is often interrupted, reports Arianne Cohen for Fast Company. “The researchers say their findings suggest that sleep quality may be essential,” writes Cohen. “Participants experienced many nightly sleep interruptions, a saga familiar to anyone who lives with children.”
Professor of the practice emeritus Marcia Bartusiak discusses the future of space travel and exploration with Radio Boston host Tiziana Dearing. “I believe it is our destiny to be in space, to really be the caretakers of the solar system,” says Bartusiak. She adds that “there needs to be oversight and it has to be global.”
Profs. Esther Duflo and Abhijit Banerjee speak with Axios reporter Dave Lawler about how the failure of rich countries to share Covid-19 vaccines and financial assistance will exacerbate global poverty and lead to increased resentment. "Nobody is talking of expanding aid,” says Banerjee. “I think the psychology, unfortunately, in rich countries somehow — even though the U.S. is going to grow faster in this year than it has in modern memory — is that we are in dire straits and we need to keep resources.”
Forbes reporters Amy Feldman and Aayushi Pratap spotlight Vicarious Surgical, a startup founded by MIT graduates that is developing a tiny robot paired with a VR headset for abdominal surgeries.
A new study co-authored by postdoctoral associate Michaël Marsset details how two red objects that have been discovered in the asteroid belt between Mars and Jupiter appear to have originated beyond Neptune, reports Jonathan O’Callaghan for The New York Times. “In order to have these organics, you need to initially have a lot of ice at the surface,” explains Marsset. “So they must have formed in a very cold environment.”
Senior research engineer Howard Herzog speaks with Bloomberg about the challenges facing the carbon capture industry and how we can get to net-zero emissions.
Washington Post columnist David Von Drehle spotlights MIT startup Form Energy, which has created a battery prototype made of iron and oxygen that stores large amounts of power and can release it over days. Von Drehle writes that this new battery could usher in a “sort of tipping point for green energy: reliable power from renewable sources at less than $20 per kilowatt-hour.”
A new study by researchers from MIT and Tulane finds that the MBTA subway network faces the threat of flooding caused by rising sea levels over the new 50 years, reports the Associated Press. “A 100-year storm would completely inundate the Blue Line and large portions of the Red and Orange lines by 2030, researchers found. By 2070, a 100-year storm would flood nearly the entire network.”
A new study by researchers from MIT and Tulane University finds that rising seas have the potential to inundate the MBTA’s network and underscores the importance of fortifying the system’s infrastructure, reports Andrew Brinker for The Boston Globe. “Severe flooding is a grave challenge for the T,” explains graduate student Michael Martello.
MIT researchers have found that while battery and fuel production for electric vehicles creates higher emissions than traditional cars, those emissions are offset by the greater energy efficiency of EVs. “Currently, the electric vehicle in the U.S., on average, would emit about 200 grams of CO2 per mile,” says senior research scientist Sergey Paltsev. “We are projecting that with cleaning up the grid, we can reduce emissions from electric vehicles by 75%, from about 200 (grams) today to about 50 grams of CO2 per mile in 2050.”
Former MIT Professor Steven Weinberg, “a theoretical physicist who discovered that two of the universe’s forces are really the same,” has died at age 88, reports Dylan Loeb McClain for The New York Times.
Writing for the Financial Times, Andrew McAfee, a principal research scientist and co-founder of the MIT Initiative on the Digital Economy, examines how new proposals in the EU to regulate AI could hinder innovation. “Restricting the field of potential innovators to those who can afford high upfront costs is a bad idea,” writes McAfee. “It leads to slower progress and growth and fewer hometown success stories, which are also risks.”
