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.
QUICK FLASH The light from a distant star may temporarily brighten when a free-floating planet passes in front of the star. This artist’s illustration shows how a rogue planet’s gravity distorts and focuses distant starlight as a ring around the planet.
