In the July 8 SN: DNA traces many roads to domestication, seeking quantum supremacy, the 25th anniversary of the qubit, bones’ secret messages, how monkeys see faces, redating Homo sapiens, a record-breaking gas giant, strange dragonfly wings and more.
MAJORANAS IN MOTION Majorana fermions (blue, red, and purple lines) travel through a topological insulator (horizontal bar) with a superconductor layered on top in this illustration of new experiments to detect the fermions. Green lines indicate electrons travelling on the edges of the topological insulator.

ORDER FROM DISORDER Maxwell’s Demon (illustrated above) is a hypothetical creature that could illegally decrease entropy, or disorder, by separating faster molecules (blue) from slower ones (green) within a box of gas. Scientist have probed this demon’s memory for the first time.

BEAM ME UP, SCOTTY China’s quantum satellite has met two more milestones, performing quantum teleportation and transmitting quantum encryption keys through space. Scientists teleported the properties of photons, or particles of light, from a ground station in Tibet (shown in this composite photo) to the satellite.
