MIT researchers developed a new method to model how climate change will impact the number of “outdoor days” and found that Southern states in the U.S. will lose a significant number of outdoor days, reports Kristin Toussaint for Fast Company. Prof. Elfatih Eltahir explains that the concept of outdoor days is, “an attempt for me to bring the issue of climate change home. When someone tells you global temperatures are going to increase by 3 degrees, that’s one thing. If someone tells you that your outdoor days will be dropping by 20% or 30%, that’s another thing.”

Researchers from MIT and elsewhere have developed a new technique that removes lead from water using repurposed beer yeast, reports Boston 25 News. The researchers “developed a hydrogel capsule to hold the yeast after it is cleaned, freeze-dried, and ground into a powder,” explains Boston 25. “Researchers said the yeast capsules could be modified to remove other dangerous contaminants from water, including PFAS and microplastics.” 

Researchers at MIT and elsewhere have developed a filter from used brewery yeast capable of removing lead and other metals from water, reports Rich Johnson for NewsNation. “Through a process called biosorption, the yeast can bind to lead, as well as the metals commonly used in electronic components,” explains Johnson. “That, say the researchers, could be a game-changer when recycling those metals. But the more valuable impact may be the ability to filter drinking water, starting with home faucets, and eventually scaling up to serve municipal water systems.” 

Prof. Jongyoon Han and research scientist Junghyo Yoon have developed a new portable desalination device that can deliver safe drinking water at the push of a button, reports Meghan Gunn and Kerri Anne Renzulli for Newsweek. The device “requires less power than a cell phone charger to run and produces clean drinking water that exceeds World Health Organization standards,” writes Gunn and Renzulli.

In an effort to combat the use of air conditioners, MIT researchers have developed a passive cooling system that relies on evaporation and radiation and requires no electricity, reports Camille Bond for EnergyWire. “With passive cooling, the advantage is that you can address the ever-increasing need for cooling with a very low carbon footprint,” explains postdoc Zhengmao Lu.

Researchers from MIT’s Research Laboratory for Electronics have developed a portable desalinator that can turn seawater into safe drinking water, reports Ian Mount for Fortune. Research scientist Jongyoon Han and graduate student Bruce Crawford have created Nona Technologies to commercialize the product, writes Mount.

MIT researchers have “developed a free-floating desalination unit consisting of a multilayer evaporator that recycles the heat generated when the water vapor condenses, boosting its overall efficiency,” reports Nell Lewis for CNN. “Researchers suggested it could be configured as a floating panel on the sea, delivering freshwater through pipes to the shore, or it could be designed to serve a single household, using it atop a tank of seawater,” writes Lewis.

MIT researchers developed a suitcase-sized, portable desalination device that can turn salt water into drinking water with the push of a button, reports Elissaveta M. Brandon for Fast Company. Brandon writes that the device could be a “vital tool for remote island communities, seafaring cargo ships, and even refugee camps located near water.”

Motherboard reporter Audrey Carleton writes that MIT researchers have developed a “filter-less portable desalination device that uses an electrical field generated by solar energy to repel charged particles like salt, bacteria, and viruses.” Research Scientist Junghyo Yoon explains that: “All indicators tell us that water scarcity is a growing problem for everyone due to rising sea levels. We don’t hope for a grim future, but we want to help people be prepared for it.” 

A new portable, solar-powered desalination device developed by MIT researchers can create potable drinking water with the push of a button, reports Tony Ho Tran for The Daily Beast. “The device doesn’t rely on any filters like traditional desalination machines,” writes Tran. “Instead, it zaps the water with electric currents to remove minerals such as salt particles from the water.”

The Washington Post Editorial Board highlights a new report co-authored by MIT researchers that finds keeping the Diablo Canyon nuclear power plant in California open would help the state reach its climate goals. "The experts project that keeping Diablo Canyon open just one more decade would cut California’s power-sector emissions by more than 10 percent, because it would burn far less gas, and save the state $2.6 billion in power system costs."

Los Angeles Times reporter Rob Nikolewski spotlights a report by researchers from MIT and Stanford University that finds keeping the Diablo Canyon Power Plant in California running would reduce electricity costs and help the state achieve its climate goals. “Nuclear plants – and Diablo Canyon is no exception – are one such clean and firm [source of] power capacity that we think should be preserved,” says Prof. Jacopo Buongiorno.

Forbes reporter Ken Silverstein highlights a joint study by MIT and Stanford researchers that finds that extending the California Diablo Canyon Power Plant will save customers billions while reducing carbon emissions. The researchers found that “if the plant stayed operational from 2025 to 2035,” writes Silverstein, “CO2 levels would drop by 10% a year and displace natural gas use, saving customers $2.6 billion.”

Bloomberg reporter David R. Baker writes that a new report co-authored by MIT researchers keeping California’s last nuclear power plant open could help reduce energy costs and provide water to the state. Keeping the “Diablo Canyon open through 2035 would cut greenhouse-gas emissions from California’s power sector 10% each year, by reducing the amount of electricity needed from natural-gas plants,” writes Baker.

A new report by researchers from MIT, Stanford and other institutions finds that extending the life of the Diablo Canyon nuclear power plant in California should help the state meet its climate goals, reports Timothy Gardner for Reuters. The researchers found “delaying closure of the plant to 2025 would reduce California's carbon emissions from power plants by more than 10% from 2017 levels, reduce dependency on natural gas, and save up to $21 billion in power system costs.”
