Your Breasts Are Trying To Kill You: Slate reviews Breasts: A Natural and Unnatural History by Florence WIlliams (an edited excerpt from the book re: breast milk in The Guardian - includes breastfeeding photo). NPR interview with Williams (41 min. audio and text highlights); a brief interview with Williams in The Star and a long interview in Maclean's. A recent piece by Williams in Slate: A new set of reports shows that federal policy on chemicals testing neglects breast health. Subject found via a post on IBTP discussing the ban, and then partial retraction of that ban, on allowing breast cancer survivor Jodi Jaecks to swim topless at a Seattle public pool - includes topless photo. Some may consider the photos noted NSFW.
Walter Randelshofer's Pretty Patterns collection (for Rubik's cubes up to 5x5x5) is one of the nicest twisty puzzle sites going. It's based on his CubeTwister software, which you can download (including a lovely OS X standalone). If you really want a treasure trove of twisty polyhedra, check out gelatinBrain's enormous collection of java applets (which unfortunately don't do so well on macs). Are those things even physically possible? Really? Mini bonus: Randelshofer also hosts an archive of fondly-remembered Amiga animations.
