John Yang reports for PBS NewsHour about technologies to harvest fog to secure the world’s water supply, including one system designed by Prof. Kripa Varanasi to collect water from power plant cooling towers. Varanasi and his team “discovered that zapping air rich in fog with a beam of electrically charged particles draws the droplets toward the mesh, dramatically increasing its ability to collect water,” says Yang.
A new MIT study shows that “China’s move away from fossil fuels would mean 2,000 fewer premature deaths in the U.S. by 2030,” reports John Fialka for E&E News. "It reminds us that air pollution doesn't stop at national boundaries," said Prof. Valerie Karplus, a co-leader of the paper.
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 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.”
The BBC series “Follow the Food” spotlights how MIT researchers are tackling the issue of runoff pesticide pollution by developing a technology that helps pesticide better adhere to plant leaves. “What we are trying to do is come up with a technology that can help farmers and significantly reduce the amount [of pesticide] sprayed,” explains Prof. Kripa Varanasi.
MIT’s Solve initiative is accepting solutions for its Circular Economy Challenge, which focuses on renewable energy and waste elimination. “Ideas that help communities move towards zero waste and zero carbon through STEM education on new design and production techniques could win the GM Circular Economy Prize,” writes Natalie Parletta for Forbes.
A new study co-authored by MIT researchers finds that factories in China have been emitting a compound banned under the Montreal Protocol that destroys the Earth’s ozone layer, reports Yen Nee Lee for CNBC. The researchers found that “China accounted for 40% to 60% of the global increase in trichlorofluoromethane, or CFC-11, emissions between 2014 and 2017.”
Technology Review reporter James Temple spotlights a new study co-authored by MIT researchers that finds factories in China are using a banned compound. The finding underscores the need for monitoring adherence to pollution accords, explains Prof. Ronald Prinn. “At the end of the day, any treaty that doesn’t have an independent verification mechanism isn’t going to be successful,” he explains.
Axios reporter Andrew Freeman writes that a new study co-authored by MIT researchers finds that factories in northern China have been using the banned CFC-11 compound, which eats away at the Earth’s ozone layer. Prof. Ronald Prinn explains that CFC-11 stays in the atmosphere for 52 years and even “with no emissions, it still lingers on and on and on.”
Bloomberg News reporter Carol Massar spotlights how MIT researchers have developed a robot that can identify and sort recyclables. “The system includes a soft Teflon hand that uses tactile sensors to detect the size of an object and the pressure needed to grasp it,” Massar reports. “From there it can determine if it’s made of metal, paper or plastic.”
Scientific American reporter Jeremy Hsu highlights how CSAIL researchers have developed a robot that can automatically sort recycling. The robot “uses soft Teflon ‘fingers,’ which have fingertip sensors to detect object size and stiffness,” Hsu explains.
A new study by MIT researchers provides evidence that life on Earth may have begun in shallow bodies of water, reports Martin Finucane for The Boston Globe. The researchers found that ponds “could have held high concentrations of a key ingredient, nitrogen, while that would have been less likely in the ocean,” Finucane explains.
A new study by MIT researchers provides evidence that the first life on Earth likely came from shallow ponds, not oceans, reports the Xinhua news agency. The researchers found that primitive ponds that were about “10 centimeters deep had higher concentrations of nitrogen, a key ingredient for life on Earth.”
Fast Company reporter Jesus Diaz writes that MIT researchers have developed a computer model that shows that rising water temperatures will cause the color of the world’s oceans to change.
MIT researchers have found that climate change will cause half of the world’s oceans to change color by 2100, reports Becky Ferreira for Motherboard. “Monitoring ocean color could yield valuable insights into the effects of climate change on phytoplankton,” Ferreira explains.
