Boston Globe reporter Hiawatha Bray writes that MIT researchers have used an AI system to identify a potential new Covid-19 vaccine that may be effective against both current and future variants of the virus. “The new vaccine targets a portion of the COVID virus that is much less prone to evolve,” writes Bray. “That could potentially make it effective against many different versions of the virus, eliminating the need for routine booster shots.”
Rebecca Blank PhD ’83, who helped reform how the government measures poverty, has died at 67, reports Alex Traub for The New York Times. Blank’s work “changed the poverty calculus in numerous ways, for instance by using as a basis not merely food budgets but also an array of consumer expenditures, including on clothing and shelter,” writes Traub. “In addition, it updated the view of a family’s financial resources to take account of government benefits not issued as cash.”
Bloomberg reporters Alex Tanzi and Mackenzie Hawkins spotlight a paper by graduate student Evan J. Soltas and his colleague Gopi Shah Goda discussing Covid-19’s impact on the labor market. The researchers “found that workers who miss a full week because of COVID are about 7 percentage points less likely to be employed a year later,” writes Tanzi and Hawkins.
MIT researchers have developed a new approach to vaccines that uses “a machine learning twist [that] could put an end to boosters and seasonal variant shots,” reports Devin Coldewey for TechCrunch.
Katie Rae, chief executive officer and managing partner of The Engine, speaks with Bloomberg reporter Akshat Rathi about how climate-tech startups are often well served by having scientists and engineers serve as leaders, in particular when surrounded by established business talent. “In the earliest phases of these things, you cannot just divorce the science from the scientist or divorce the engineering from the engineer,” says Rae.
Postdoc Saverio Cambioni speaks with Andrew Corselli of Tech Briefs about NASA’s DART mission, which was aimed at testing a method to protect Earth in case of an asteroid impact threat. “DART showed that it is technologically possible to intercept and impact a sub-kilometer asteroid, with limited prior knowledge of its shape and surface properties,” Cambioni explains.
Carlos Casanovas MS ’14 co-founded X1 Wind, a startup that has developed a floating wind turbine prototype, reports Andrew Paul for Popular Science. “Floating wind is set to play a vital role supporting the future energy transition, global decarbonization and ambitious net-zero targets,” says Casanovas.
Researchers at MIT have predicted that without improvements in hardware efficiency, energy consumption and emissions from autonomous vehicles could be “comparable to that of data centers today,” reports Sarah Wells for Popular Mechanics. “In order to reduce the future carbon footprint of AVs, scientists will need to make the computing systems of AVs, including smart sensors, far more efficient,” writes Wells.
Chronicle visits the new MIT Museum, highlighting a number of exhibits, including one exploring the research behind the hunt for gravitational waves and another that examines the impacts humans are having on the environment. “We try to be a window, going both ways, between MIT and the rest of the public,” explains Prof. John Durant, director of the MIT Museum. “We’re also trying to get people to have a glimpse of how a world-class research institution actually works.”
Researchers from MIT have found that wildfire smoke can activate chlorine-containing molecules that destroy the ozone layer, writes Donna Lu for The Guardian. “The question in my mind is: is the man-made chlorine going to get … diluted and destroyed out of the atmosphere faster than global climate change is going to increase the frequency and intensity of this kind of fire?” says Prof. Susan Solomon. “I think it’s going to be a race.”
Axios reporter Jacob Knutson highlights a new study by MIT researchers that finds the smoke released by major wildfires likely reactive chlorine-containing molecules in the atmosphere, delaying the recovery of the hole in the ozone layer. The researchers developed a model that found smoke released by Australian wildfires “chemically depleted between 3% to 5% of the total ozone column in the Southern Hemisphere mid-latitudes in June and July of 2020.”
New Scientist reporter James Dinneen writes that a new study by MIT researchers finds the smoke from Australian wildfires “may have enabled hydrochloric acid to dissolve at higher temperatures, generating more of the reactive chlorine molecules that destroy ozone.” Research scientist Kane Stone explains that “satellite observations showed chemistry that has never been seen before.”
MIT scientists have found that the Australian wildfires in 2019 and 2020 unleashed remnants of chlorine-containing molecules in the stratosphere, expanding the ozone hole and suggesting that more frequent wildfires could threaten the ozone hole’s recovery, reports Dyani Lewis for Nature. “It’s like a race,” says Prof. Susan Solomon. “Does the chlorine decay out of the stratosphere fast enough in the next, say, 40–50 years that the likely increase in intense and frequent wildfires doesn’t end up prolonging the ozone hole?”
Writing for The Hill, Prof. Yossi Sheffi examines several strategies companies could use to help improve supply chain sustainability, including redesigning last-mile deliveries, influencing consumer choices and incentivizing returnable containers. “Supply chains can be designed to reduce emissions from operations and to reorient their buying behavior in support of carbon emissions reductions,” writes Sheffi.
Nature highlights the Rising Stars program at MIT, which “offers mentoring and support for researchers from historically marginalized or under-represented groups, as they move through their careers.” Nature notes that the program stems from Prof. Emerita Nancy Hopkins’ advocacy for gender equality in academic.
