A study from MIT and elsewhere has found that a new building code in Massachusetts designed to promote “net zero” development, “would increase construction costs and potentially worsen the state’s housing crisis,” reports Greg Ryan for NBC Boston.
NBC Boston’s Jeff Saperstone visits MIT to learn more about how researchers discovered that a common hydrogel used in cosmetic creams, industrial coatings and pharmaceutical capsules can absorb moisture from the atmosphere as the temperature rises. The material could one day be used to harvest moisture for drinking water or feeding crops. “For a planet that's getting hotter, this could be a game-changing discovery,” Saperstone notes.
Boston Globe columnist Thomas Farragher spotlights how researchers from MIT’s Haystack Observatory have built an “ice penetrator,” a device designed to help scientists study how sea ice is changing. Chris Eckert, a mechanical engineer at Haystack, explains, “Global warming is a real thing and we need a new class of instrumentation and measurements to truly understand it.”
Lisa Dyson PhD ‘04 founded Air Protein, a company looking to “bring recycled carbon cultivated into food with the taste and texture of chicken, meat, and seafood,” reports Geri Stengel for Forbes.
Financial Times reporter Simon Mundy and Kaori Yoshida spotlight Gradiant, an MIT startup that has developed new methods of handling industrial wastewater. “Gradiant promises customers that its technology will allow them to purify and reuse larger amounts of water, reducing the amount they need to source externally,” write Mundy and Yoshia.
Boston Globe reporter Aaron Pressman highlights Gradiant, an MIT startup that has developed a water purification system based on natural evaporation and rainfall cycles to clean wastewater at factories and manufacturing facilities.
Gradiant, an MIT startup, is using water technology to “help companies reduce water usage and clean up wastewater for reuse,” reports Simon Jessop for Reuters.
Prof. Christopher Knittel speaks with Radio Boston host Tiziana Dearing about how high electric bills are impacting efforts to address climate change. The current artificial inflation of the volumetric rate “makes electrification hard, it makes it more expensive,” notes Knittel. “As we, as a Commonwealth, want to move toward electrification, it’s a big headwind that is going to push against our climate goals,” says Knittel.
“The Sun Queen,” a new documentary on PBS, will highlight the life of the late former MIT Prof. Mária Telkes and her work in developing solar energy. Telkes is known for her “work on the 1948 Dover Sun House, a solar-heated model home created by an all-female team,” reports Erin Blakemore for The Washington Post.
In an opinion piece for The Boston Globe, Prof. Christopher R. Knittel explains why electricity bills in Massachusetts can be so high and how to address the issue. “State law requires Massachusetts to cut greenhouse gas emissions relative to 1990 levels by 50 percent by 2030 and by 85 percent by 2050,” writes Knittel. “In short, we need to replace gasoline and natural gas with electricity. But how we price electricity is making this effort to address climate change harder."
MIT scientists have uncovered evidence that wildfire smoke particles can lead to chemical reactions in the atmosphere that erode the ozone layer, reports Margaret Osborne for Smithsonian Magazine. “From a scientific point of view, it’s very exciting to see this brand new effect,” says Solomon. “From a planetary point of view… it would be just tragic to have mankind screw up solving the ozone hole by deciding that we’re going to [allow] a lot more of these fires if we don’t mitigate climate change.”
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.
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.”
