Editor's Selections: Phobias, Dancing, and Retinas in Dishes

Here are my Research Blogging Editor's Selections for this week.

• To start with, is there anything that might help with exposure therapy for specific phobias? Michelle from C6-H12-O6 describes a paper that suggests that the administration of cortisol might!
• While many people claim to not be able to dance, if pressed, most could dance to a beat. Nearly all of us can at least identify when others are on or off rhythm. Over at Neuropoly, DJ discusses a newly discovered form of congenital amusia: beat deafness.
• If there is anything cooler than a retina grown in a dish, I'm not sure what it is. Ambivalent Academic has the details in a killer guest post at Neurotic Physiology.
