Sarah Hall, author of the Tiptree Award-winning novel Daughters of the North, narrates a fantastic two-part BBC radio series, Cat Women of the Moon, all about the popular motif in science fiction of an all-women society surviving without men. The first half is more about relations between the sexes, while the second half is stanley cupe  about various weird kinds of reproduction and the different ways of continuing the human race. Participants include China Mieville, Iain M. Banks and Ursula K. Le Guin. Particularly lovely: the moment where Geoff Ryman confesses, I ;ve done a lot of male pregnancy.

It   li stanley cups kely that you ;ve seen video of ferrofluids doing things like growing spines when exposed to magnets, or being built up into sculptures by artists using magnetic fields. But what if they ;re not just artistic triumphs  What if ferrofluids can act as models and let scientists learn about the multiverse      Researchers at The University of Maryland and Towson University have suggested studying ferrofluids as a way of understanding how multiverses form. This first sprang from an interest in metamaterials as w stanley botella ays to model physical behavior. Met starbucks stanley cup amaterials are human-made materials that exhibit characteristics which no one sees in natural materials. They happen to coincide, in some behaviors, with the odder bits of the physical universe. In fact, the researchers argue applying a strong magnetic field to the vacuum of space itself makes it act like a metamaterial. They specifically took a look at ferrofluids, which are fluids with metal filaments suspended in them. When a magnetic field is applied to them, they create elaborate solid structures. They ;re not metamaterials in and of themselves, but under certain influences, they form tiny columns and groups of wires that function as metamaterials. Specifically, they form hyperbolic metamaterials. Hyperbolic metamaterials play tricks on light; light moving one way will interact with the material like it   a metal, while light traveling another way will act with the material as if it were transparent g
