'Even dying stars could host planets with life—and if such life exists, we might be able todetect it within the next decade. This encouraging result comes from a new theoretical studyof Earth-like planets orbiting white dwarf stars. Researchers found that we could detectoxygen in the atmosphere of a white dwarf's planet much more easily than for an Earth-likeplanet orbiting a Sun-like star.' White dwarfs continue to radiate for a long time. Any Earth-like planet orbiting one could be very, very old...
Helicoprion, a shark from the early Permian with a single spiral tooth, shaped like a buzzsaw.
Remote sensing in rats. 'It’s not telepathy. It’s not the Borg. But we created a new central nervous system made of two brains.'
'I sometimes wonder if the success of books such as Twilight and Fifty Shades is itself a form of mass PTSD or Stockholm syndrome—a reaction to the ubiquity of violence against women and to the way in which stories of sexual violence, real or feigned, have become a culturally accepted form of entertainment; and a reaction to the often intolerable pressures of living in a world where power is still mostly in the hands of men.' Elizabeth Hand on women in fiction who fight back.
