Many multicellular animals respond to disease-causing agents, termed pathogens, using an evolutionarily conserved defence pathway called the cGAS–STING pathway1,2. Reports in the past few years of cGAS- and STING-like proteins in bacteria raised the possibility that this pathway is more evolutionarily ancient than was previously thought3–5. Writing in Nature, Morehouse et al.6 demonstrate that a

There were no readily accessible oxygen billions of years in Earth’s past, and scientists now think that arsenic, a known poison, may have helped early life on our planet breathe. In the Atacama Desert in Chile, in Laguna La Brava, researchers study photosynthetic microorganisms that live in a hyper-saline lake that is permanently and utterly devoid of oxygen. They published their research
