Prof. Fadel Adib speaks with BBC reporter Gareth Mitchell about a new battery-free underwater navigation system that his group developed. Adib explains that one of the key developments behind the new sensors is that they can “harvest power from sound.”
Writing for The Conversation, graduate student Craig Robert Martin delves into his research exploring how the Himalayas were created. “By decoding the magnetic records preserved inside them, we hoped to reconstruct the geography of ancient landmasses – and revise the story of the creation of the Himalayas,” writes Martin.
MIT researchers have developed a new battery-free, underwater navigation system, reports Darrell Etherington for TechCrunch. “Ultimately, the system and future versions that are based on the same technology could enable future robotic submarine explorers to better map the ocean floor,” writes Etherington, “and perform all kinds of automated monitoring and sub-sea navigation.”
Institute Professor Emeritus Mario Molina, who former Vice President Al Gore called a “trailblazing pioneer of the climate movement,” has died at age 77, reports John Schwartz for The New York Times. Molina shared a “Nobel Prize for work showing the damage that chemicals used in hair spray and refrigerators wreak on the ozone layer, which led to one of the most successful international efforts to combat environmental risk.”
Guardian reporter Fiona Harvey memorializes the life and work of Institute Professor Emeritus Mario Molina, known for his research uncovering the impact of CFCs on the ozone layer. Harvey notes that Molina’s work, “will also help to avert ruin from that other dire emergency, the climate crisis.”
Institute Professor Emeritus Mario Molina, known for his work demonstrating the risk of CFCs to the ozone layer, has died at age 77, reports Emily Langer for The Washington Post. Langer notes that Molina was also “a prominent voice in debates about how best to combat climate change.”
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.”
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.
A new study by MIT researchers examines the environmental impact of the Covid-19 pandemic, reports Steven Reinberg for HealthDay. "If the pandemic leads to a persistent global recession, there is a real threat to the adoption of clean technology, which could outweigh any 'silver lining' in environmental benefits," says Prof. Jing Li.
Verge reporter Justine Calma writes that states in the Midwest and Great Lakes region could see $4.7 billion in health benefits by maintaining current renewable energy standards. “This research shows that renewables pay for themselves through health benefits alone,” explains Emil Dimanchev, senior research associate at MIT’s Center for Energy and Environmental Policy Research.
A new study by MIT researchers examining the impact of energy policies that reduce fine particulates in the air finds that there are “substantial health benefits in Rust Belt states when utilities are required to supply escalating amounts of renewable power,” reports Ben Geman for Axios.
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.”
