Prof. Asegun Henry founded Fourth Power, a startup using new technology to cut the cost of storing renewable energy, reports Adele Peters for Fast Company.  The technology is designed “to tap into excess renewable energy,” explains Peters. “That energy heats up liquid tin, which flows down carbon pipes to heat up the blocks. When the grid needs electricity again, the system generates it using special solar panels that run on the white-hot light from the pipes rather than sunshine. Because the system was designed for durability, the team expects it to last for three decades—far longer than lithium-ion batteries, which quickly degrade.”

Researchers from MIT and elsewhere have found that “showing AI-generated images of a less car-reliant American city boosted support for sustainable transportation policies,” reports Linda Poon for Bloomberg. “Let’s help them imagine what it would actually be like to live in a car-less neighborhood, and a car-less city,” says postdoctoral associate Rachit Dubey. 

BBC Science Focus reporter Alex Hughes spotlights a new study by MIT scientists that suggests more heavy snowfall and rain linked to climate change could increasingly contribute to earthquakes worldwide. “The researchers made these conclusions based on how weather patterns in northern Japan have seemingly contributed to a new 'swarm' of earthquakes,” writes Hughes, “a pattern of multiple, ongoing quakes – that is thought to have begun in 2020.”

Prof. Kripa Varanasi and Vishnu Jayaprakash SM '19, PhD '21 co-founded AgZen, an MIT spinoff that is developing new technologies to improve the performance and effectiveness of pesticide treatments, reports The Economist. The new technologies “could reduce the total amount of fungicides and insecticides sprayed over complete crops by some 90%, as well as cutting the amount of adjuvants required,” writes The Economist.

A new study conducted by MIT researchers suggests “heavy snowfall could be a factor in triggering swarms of earthquakes,” reports Evan Bush for NBC News. "Those big snowfall events seem to correlate well with the start of these big earthquake swarms," says Prof. William Frank. "We shouldn’t forget the climate itself can also play a role in changing the stress state at depth where earthquakes are happening." 

Prof. John Sterman speaks with New York Times reporter Susan Shain about the effectiveness of flight offsets. Sterman explains that few offset project results are verifiable, immediate and durable, part of his criteria for legitimacy. Better recommendations include insulating your home or buying an electric car.

MIT researchers have uncovered the “photomolecular effect,” a process “that demonstrates for the first time that water can evaporate with no source of heat using light alone,” reports Anthony Cuthbertson for The Independent. The “discovery could impact everything from climate change calculations to weather forecasts, while also opening up new practical applications for things like energy and clean water production,” writes Cuthbertson.

Researchers at MIT have discovered that “light in the visible spectrum is enough to knock water molecules loose at the surface where it meets air and send them floating away,” reports Michael Franco for New Atlas. “While the distinction between light-caused evaporation and heat-caused evaporation might not seem like a big one, the researchers say it could not only have a big impact on the way future evaporative projects are executed, but that it could also explain a long-standing discrepancy involving clouds,” writes Franco.

Interesting Engineering reporter Rizwan Choudhury spotlights a new study by MIT researchers that finds light can cause evaporation of water from a surface without the need for heat. The photomolecular effect “presents exciting practical possibilities,” writes Choudhury. “Solar desalination systems and industrial drying processes are prime candidates for harnessing this effect. Since drying consumes significant industrial energy, optimizing this process using light holds immense promise.”

Researchers at MIT have developed a new measure called “outdoor days,” which describes the number of days per year in which temperatures are comfortable enough for outdoor activities in specific locations around the world, reports Lebawit Lily Girma for Bloomberg News. “Changes in the number of outdoor days will impact directly how people around the world feel climate change,” says Prof. Elfatih Eltahir.

Robert Stoner, interim director of the MIT Energy Initiative, speaks with Boston Public Radio hosts Jim Braude and Margery Eagan about how the Bipartisan Infrastructure Act provides funding for hydrogen hubs around the country to create networks of hydrogen fuel producers. “We're going to use hydrogen as a substitute for natural gas. In order for that to happen, we have to get the cost way down,” Stoner explains.

Researchers from MIT and elsewhere explored the effectiveness of climate commitments made by banks to mitigate the effects of climate change, reports Nicole Goodkind for CNN. “Our results cast doubt on the efficacy of voluntary climate commitments for reducing financed emissions, whether through divestment or engagement,” the researchers note.

Researchers from MIT and elsewhere have found that climate pledges made by banks to reduce carbon emissions and finance energy transitions may not be as effective as previously thought, reports Eshe Nelson for The New York Times. “The researchers found that since 2018 the banks had reduced lending 20 percent to sectors they had targeted in their climate goals, such as oil and gas and transport,” explains Nelson. “That seems like progress, but the researchers argued it was not sufficient because the decline was the same for banks that had not made the same commitment.”

MIT researchers have developed a new tool to quantify how climate change will impact the number of “outdoor days” where people can comfortably spend time outside in specific locations around the world, reports Tim DeChant for TechCrunch. “The MIT tool is a relatable application of a field of study known as climate scenario analysis, a branch of strategic planning that seeks to understand how climate change will impact various regions and demographics,” writes De Chant.

MIT researchers are working to uncover new ways to avoid contrails and minimize their impact on global warming, reports Nicolas Rivero for The Washington Post. “Whether [the contrail impact is] exactly 20 percent or 30 percent or 50 percent, I don’t think anybody knows that answer, really,” says research scientist Florian Allroggen “But it also doesn’t really matter. It’s a big contributor and we need to worry about it.”
