It’s not often that there’s encouraging news on climate change but researchers at the University of California are testing a method, called enhanced rock weathering, that has the potential to act as a substantial carbon sink.

Also in this week’s science and research news: a possible treatment for treating genetic forms of ALS with an existing drug, what researchers found when they tested a large population for COVID-19, and why Florida is struggling to contain the pandemic.
