Ten weird new Jupiter moons discoveredAstronomers searching for Planet Nine have instead discovered ten more moons orbiting Jupiter. All are tiny — between about 1 and 3 kilometres across — and 7 of them travel in remote orbits and in the reverse direction from the planet’s rotation. One oddball moon orbits in the opposite direction from its closest neighbours, putting it on a collision course with them. All this weirdness suggests that the moons didn’t form with Jupiter, but were probably captured after the gas giant’s birth. Nature | 3 min read |

Scientists: “We won’t build killer robots”The co-founder of Google DeepMind and car, spaceship and cave-submarine magnate Elon Musk are among more than 2,400 artificial-intelligence researchers who have signed a pledge against killer robots.

The document also calls on governments to outlaw such technology. The Guardian | 5 min read |

Novichok-contaminated bottle foundUK police have found a bottle contaminated with the nerve agent Novichok in the house of one of two recent British victims. One of them, Dawn Sturgess, has died from the poison. The fact that the original compound was found on the bottle, and on the victims’ hands and clothing, suggests it was engineered to be relatively stable. Police are working to determine whether the poison is indeed the same nerve agent used to attack a former Russian double agent in March. Chemistry World | 6 min read |

Uncertainty and fertility in academiaFemale academics often work contract to contract during the years when they are considering starting a family. “This, for me, should be the real business of initiatives like Athena Swan, which try to ensure women progress in the workplace,” argues sustainability researcher Lucie Middlemiss. “How do we find ways of allowing women to be both academics and mothers in the context of precarious contracts?” Mama is an Academic blog | 4 min read |

The sci-fi novel CP Snow suppressedChemist CP Snow — renowned for his 1959 “two cultures” lecture lamenting the intellectual divide between the sciences and the humanities — also wrote 17 novels. One of them, he wished he hadn’t: New Lives for Old, about an anti-ageing treatment that ultimately undermines society. Historian Catherine Oakley explores the sex and sexism in what Snow called “the book which will not appear again”. Palgrave Communications | 40 min read |

Ask them.”The International Union of Geological Science hasn’t included ‘Anthropocene’ in its latest chart defining the periods, epochs and ages of geologic time.
