Yeah, I’d domesticate these guys before wolves. Photo by law_kevin.

Let’s just take my passive-aggressive hint to like Denim and Tweed on Facebook as read this week, shall we?

• Science blogging gets interdisciplinary. Scicurious and Kate Clancey evaluate the neurology and endocrinology behind a study of pre-menustrual dysphoric disorder.
• Belyaev’s domesticated foxes are back, with minks and rats. The “domestication syndrome” of animals selected to live with people may have the same genetic origins in many mammal species.
• They are mighty cuddly. A new archaeological find suggests that there was at least one pet fox in a Pleistocene human settlement.
• Only one possible name for that illusion. With the right visual cues and some careful tactile stimulus, it’s possible to convince people they have a third hand.
• Fresh country air has lots of germs. Children raised in the diverse bacterial communities found on farms are less likely to develop asthma.
• It’s a tricky bugger. Curing HIV isn’t going to be easy, but there are some new lines of attack that look promising.
• In case you missed it. I wrote a guest post for Scientific American!
