Imagining an All-Renewable Grid With No Blackouts Without Long-Duration Batteries (stanford.edu)

A significant finding of the study was that long-duration batteries were neither needed nor helpful for keeping the grid stable. Instead, grid stability could be obtained by linking together currently available batteries with storage durations of four hours or less. Linking together short-duration batteries can provide long-term storage when they are used in succession. They can also be discharged simultaneously to meet heavy peaks in demand for short periods. In other words, short-duration batteries can be used for both big peaks in demand for short periods and lower peaks for a long period or anything in-between.

Can Invasive Fish Be Scared Off With a Menacing Robot Predator? (nytimes.com)

The robot not only freaked the mosquitofish out, but scarred them with such lasting anxiety that their reproduction rates dropped; evidence that could have long term implications for the species' viability, according to the paper. "You don't need to kill them," Dr. Polverino said. Instead, he said, "we can basically inject fear.*

Scientists Discover Seaweed Species That Stops Cows from Emitting Methane (cbsnews.com)

The increase motivated chief scientist at Futurefeed, Rob Kinley, who worked with Dorgan on his organic certification 15 years ago, to find a seaweed species with even more methane-reducing power. "We started testing seaweeds from coastal Australia, and it wasn't long before the Asparagopsis species showed up, and it showed up in a big way. So big that we didn't even believe what we were seeing," Kinley said. "It took multiple runs of testing this before we believed what we were seeing, which was we couldn't find methane anymore." Kinley's research showed Asparagopsis, a common type of red seaweed, has the potential to virtually eliminate methane emissions from livestock.

Melting Glaciers May Create New Pacific Salmon Habitat, Study Finds (upi.com)

As glaciers in the mountains of western North America melt, or retreat, they could produce around 4,000 miles of new Pacific salmon habitat by the year 2100, the data showed. After modeling glacier retreat under different climate change scenarios, the glaciers could reveal potential new Pacific salmon habitat nearly equal to the length of the Mississippi River under moderate temperature increases, the researchers said.

"We predict that most of the emerging salmon habitat will occur in Alaska and the transboundary region, at the British Columbia-Alaska border, where large coastal glaciers still exist," co-author Kara Pitman said in a press release....

Why yes, I am using The Lounge for an online scratch pad.
