Cargo-sorting molecular robots, humans as the ultimate fire starters, and molecular modeling with quantum computers

This week we hear stories on the gut microbiome’s involvement in multiple sclerosis, how wildfires start—hint: It’s almost always people—and a new record in quantum computing with Online News Editor David Grimm.

Andrew Wagner talks to Lulu Qian about DNA-based robots that can carry and sort cargo.

Sarah Crespi goes behind the scenes with Science’s Photography Managing Editor Bill Douthitt to learn about snapping this week’s cover photo of the world’s smallest neutrino detector.
