In the October 1 SN: Meet the SN 10 — up-and-coming scientists exploring big questions, Tasmanian devils resist an epidemic of cancer, the ebb and flow of one man’s microbiome, oldest fossils, Juno’s first closeups of Jupiter and more.
DIM SUN Scarce oxygen and abundant sulfate prevented methane concentrations from getting high enough to explain why Earth didn’t freeze over around 1.8 billion to 800 million years ago when the sun was dimmer, researchers say.
