Boston Globe reporter Pranshu Verma spotlights MIT startup Biobot Analytics, co-founded by Mariana Matus ’18 and Newsha Ghaeli ’17, for their work studying sewage data to better predict the spread of Covid-19 in communities. “For health officials, it [the data] confirms whether Covid spikes in the community are real, and not due to increased testing or other factors,” writes Verma. “Moreover, Covid levels in waste water are a leading indicator for new clinical cases, giving health officials a few days’ notice if they’ll see more sick patients showing symptoms.”

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.”

Forbes contributor David Bressan writes that a new study co-authored by MIT researchers finds that images taken by the Perseverance rover show that Mars’ Jezero crater was once a lake. “The fine-grained clay and carbonate layers deposited in the fossil lake are capped by a diamict, a sedimentary rock consisting of a mix of large and small boulders,” writes Bressan. “Scientists think the boulders were picked up tens of miles upstream and deposited into the former lakebed by episodic flash floods, suggesting a catastrophic climate change in Mars' distant past.”

Prof. Tanja Bosak and Prof. Benjamin Weiss speak with Popular Science reporter Kate Baggaley about how their analysis of images captured by NASA’s Perseverance rover found that the Jezero crater was once a lake and river delta. “The geological history of the Jezero crater could help scientists understand how the Red Planet changed from being wet and possibly habitable into a harsh desert world,” writes Baggaley. “Definitely we hit the jackpot here,” says Weiss, 

Space.com reporter Mike Wall writes that a new study co-authored by MIT scientists finds that the Jezero crater on Mars previously hosted a big lake and river delta. “The newly analyzed photos may provide an intriguing glimpse” into Mars’ transformation to a dry landscape,” writes Wall.

Researchers from MIT and other institutions analyzed images captured by NASA’s Perseverance rover and found that Mars’ Jezero crater was a lake 3.7 billion years ago, reports Ashley Strickland for CNN. “The new information shows the importance of sending rovers to explore the surface of Mars,” writes Strickland. “Previous images captured by orbiters had shown that this outcrop resembled the kind of fan-shaped river deltas we have on Earth. Perseverance's images show definitive proof of the river delta's existence.”

MIT researchers have created a new filter from tree branches that could provide an inexpensive, biodegradable, low-tech option for water purification, writes Shaena Montanari for Popular Science. “We hope that our work empowers such people to further develop and commercialize xylem water filters tailored to local needs to benefit communities around the world,” says Prof. Rohit Karnik.

UPI reporter Brooks Hays writes that MIT researchers have created a new water filter from tree branches that can remove bacteria. “The filter takes advantage of the natural sieving abilities of xylem -- thin, interconnected membranes found in the sapwood branches of pine, ginkgo and other nonflowering trees,” writes Hays.

Scientific American reporter Prachi Patel spotlights how MIT researchers have developed a solar-powered system that can extract drinkable water from the air. “The $100 setup yields almost six liters an hour in the lab and about half of that outdoors,” writes Patel. 

Axios reporter Bryan Walsh highlights how MIT researchers have developed a new solar-powered device that can extract drinkable water from the air and “could help alleviate water scarcity in some of the world's driest regions.” Walsh notes that the new design “makes use of a more common material called zeolite, doubling its capacity to generate water.”
 

Prof. Fadel Adib has created a new underwater device that not only broadcasts and receives sound, but is also powered by sound, reports The Economist. In the future, Adib and his colleagues hope the device could be used to “transmit information about water temperature, acidity and salinity.”
