ResearchBlogging editor's selections: snails do it anti-chirally, the Tasmanian fish mystery, and an amateur impact hypothesis

skyskull "Dr. SkySkull" selects several notable posts each week from a miscellany of ResearchBlogging.org categories. He blogs at Skulls in the Stars.

Late posting of editor's selections this week -- life's events, including an emergency vet trip with a sick kitty (she's fine) -- delayed things!

  • Some snails prefer doing it anti-chiral. In our bawdiest post of the week, Kevin Zelnio of The Online Laboratory of Kevin Zelnio talk a bit about how snails procreate -- it turns out that one species of snail prefers to find mates that have shells that twist opposite to their own! *gasp!*
  • Why did the Tasmanians stop eating fish? Who doesn't love a mystery?  In an intriguing post, Greg Laden of his eponymous blog investigates what happened when early human inhabitants of islands were slowly cut off from the mainland by changing sea conditions.  The connection to fish eating is explained!
  • Amateur impact hypothesis makes it into major archaeology journal. Does an ancient Greek legend refer to a massive meteor strike in antiquity?  Martin Rundkvist of Aardvarchaeology looks at a recent paper making the case, and argues that the evidence isn't really what it's cracked up to be.

That's it for this week!  Next Monday, I'll hopefully be back on schedule!
