Researchers .... have made reported some exciting findings relating to metal-organic frameworks (MOFs), a class of porous materials, which could benefit a wide range of important gas separation processes.

ot long ago, Joe Davis, the "artist-scientist" in George Church's genetics lab at Harvard Medical School, was in Brittany, France. The region is known for thousand-year-old salterns that produce fleur de sel, or flower of salt-salt that forms as seawater evaporates. Davis was there sampling these brightly colored ponds with a microscope, and found in the shallow waters an abundance of diverse halophiles, organisms that can grow in and tolerate saline conditions. "I wondered what happens to these organisms," he said. "The salt is evaporating, the water's gone. The organisms aren't just going to disappear. Where are they?"

Data scientist Emilio Ferrara tells Nature that fake social-media accounts are harder to detect than ever before.

Globally, the USA has recorded the highest number of COVID-19 cases and deaths,1 and still needs to simultaneously respond to another looming potential pandemic. The rise in multidrug-resistant bacterial infections that are undetected, undiagnosed, and increasingly untreatable threatens the health of people in the USA and globally. In 2020 and beyond, we cannot afford to ignore antimicrobial resistance (AMR).

Charles Darwin was very likely the first person to have understood nature in terms of a game played across deep time. I have wondered how much further the Chess-playing naturalist might have taken this metaphor if, like Kawabata, he had studied Go. Unlike Chess, where the objective is to expose and capture the King by eliminating pieces, in Go the objective is to capture territory by surrounding enemy pieces, called stones, and by protecting unclaimed area.
