Washington Post reporter Chris Mooney writes that MIT researchers have found that giant cracks allow for the rapid draining of lakes on Greenland’s ice sheet. “We know that the ice sheet will continue to increase its contribution to sea level rise over the coming years,” explains lead author Laura Stevens. “The implications of this study show us more of how these processes will play out.”
MIT researchers have uncovered how the meltwater lakes atop Greenland’s ice sheet drain, reports Richard Valdmanis for Reuters. Lead author Laura Stevens explains that the findings will help “predict more accurately how supraglacial lakes will affect ice sheet flow and sea level rise.”
Team Raptor Maps received the top prize in MIT’s annual $100K Entrepreneurship Competition, reports Nidhi Subbaraman for BetaBoston. Founded by three MIT students, Raptor Maps “proposes to use camera-carrying drones to survey farmland and pinpoint damage before pests and diseases can decimate crops.”
Jordan Graham writes for The Boston Herald about a system created by Prof. Brian Williams that allows unpiloted underwater vehicles to make decisions without human intervention. Williams explains that the system was developed so that an underwater robot would not need low-level commands, “you just give it your goals.”
Brooks Hays of UPI writes that Prof. Brian Williams has developed a new system that allows autonomous underwater vehicles to operate independently. Robots using the new system “are able to navigate underwater expanses and execute research tasks on their own. Researchers simply dictate high-level goals, and the submersible calculates the most efficient path forward."
MIT researchers have developed a new system that gives underwater robots more decision-making capabilities, reports Kelsey Atherton for Popular Science. Atherton explains that developing machines that can operate without human control could “usher in a whole new age of discovery.”
A group of experts convened by MIT’s Abdul Latif Jameel World Water and Food Security Laboratory recently published a report on plans for the Grand Ethiopian Renaissance Dam, reports William Davison of Bloomberg News. The report’s authors urge greater coordination between Egypt and Ethiopia “to ensure water is shared fairly during periods of reduced flows.”
MIT hosted a debate between two panels of experts last week to discuss whether the Institute should divest its endowment from fossil-fuel companies, reports Kyle Alspach for BostInno. Each side included “an MIT faculty member, a professor from another institution and an executive from an investment firm.”
Jennifer Switzer reports for The Tech on MIT’s fossil-fuel divestment debate. “Divestment has been one of the most strongly debated potential actions of academic institutions in recent times,” said Prof. Roman Stocker, head of the MIT Climate Change Committee. “We decided: Why don’t we tackle it head-on?”
Benjamin Hulac reports for Scientific American on a debate held at MIT on whether the Institute should divest its endowment from fossil-fuel companies. The forum included a panel of experts arguing each side of the issue and responding to questions from the audience.
New research by Professor Daniel Rothman and postdoctoral associate Yossi Cohen has raised questions about the feasibility of carbon capture, reports Ken Silverstein for Forbes. The researchers found that “only a ‘small fraction’ of the carbon dioxide solidifies and turns into rock after it is injected 7,000 feet below the earth’s surface,” explains Silverstein.
In this New York Times video, James Gorman explores new MIT research examining how rainfall produces a scent. The researchers found that when raindrops hit porous surfaces they release aerosols. The scent is “not from the rain itself,” explains Prof. Cullen Buie, “it’s from the earth.”
MIT researchers have found that carbon sequestration may not be as effective at storing greenhouse gas emissions as originally thought, reports Christopher Martin for Bloomberg News. The researchers found that “much of the carbon dioxide will remain in its gaseous state, and may eventually escape into the atmosphere.”
Jared Silverman of USA Today reports on how MIT researchers have found that raindrops release aerosols when they hit the ground, causing a distinctive odor. The researchers found that “light to moderate rain produces more aerosols compared to heavy rain,” Silverman explains.
MIT researchers have found that when raindrops hit the ground they release aerosols, which produce a distinctive scent, reports Avianne Tan of ABC News. Prof. Cullen Buie explains that the findings also show how bacteria could spread through “chemicals being carried by aerosols."
