This energy storage facility under construction in southeast England uses lithium-ion batteries. CHRIS RATCLIFFE/BLOOMBERG/GETTY IMAGES Zinc-based cells promise to be cheaper and safer for grid storage May. 27, 2021 , 10:30 AM If necessity is the mother of invention, potential profit has to be the father. Both incentives are driving an effort to transform zinc batteries from small, throwaway cells often used in hearing aids into rechargeable behemoths that could be attached to the power grid, storing solar or wind power for nighttime or when the wind is calm. With startups proliferati...

Share Where debris flowed from a 1980 eruption, plants and animals have slowly returned. But a road may disrupt those ecological communities. CARRI J. LEROY Planned service road near Mount St. Helens threatens prized research area Apr. 21, 2021 , 1:00 PM When Mount St. Helens in Washington state erupted on 18 May 1980, the initial explosion blew sideways, creating a nearly 600-square-kilometer blast zone—and what has become a prized ecological research area. Dozens of groups have tracked life’s reemergence there, one lupine and ladybug at a time. Now, many of those research projec...

Science’s COVID-19 reporting is supported by the Heising-Simons Foundation. In March 2020, as the scope of the COVID-19 pandemic was coming into view, Jen Nwankwo and colleagues turned a pair of artificial intelligence (AI) tools against SARS-CoV-2. One newly developed AI program, called SUEDE, digitally screens all known druglike compounds for likely activity against biomolecules thought to be involved in disease. The other, BAGEL, predicts how to build inhibitors to known targets. The two programs searched for compounds able to block human enzymes that play essential roles in enabling the...

Feb. 25, 2021 , 12:00 PM The first organisms to “breathe” oxygen—or at least use it—appeared 3.1 billion years ago, according to a new genetic analysis of dozens of families of microbes. The find is surprising because the Great Oxidation Event, which filled Earth’s atmosphere with the precious gas, didn’t occur until some 500 million years later. “I was pretty thrilled to see this paper,” says Patrick Shih, an evolutionary biologist at the University of California (UC), Davis. The advent of proteins that can use oxygen, Shih and others say, marks a key step in the emergence of...
