Jay and Miles X-Plain the X-Men (previously) has hit its 100th episode and has a very special guest star... Chris Claremont.
The Island by Peter Watts (previously), winner of this years Hugo Award for Best Novelette. An audio version is available over at StarShipSofa (previously), itself a Hugo recipient.
Due to a rewording of the rules Science Fiction podcast StarShipSofa (previously, previously, previously) could be eligible for a Hugo award. Meanwhile the current episode features The Gambler (text version here), a story by Paolo Bacigalupi - best known as the author of The Windup Girl, one of TIME Magazine's ten books of the year ("Not just science fiction, mind, but fiction, generally") and almost certainly a favorite for the Hugo's best novel category.
