Today's selection of science news. Links are normally to press releases on EurekAlert (at the bottom end I may also add a couple of newspaper stories).

How accurately can you judge your own looks? Researchers looked at how we rate our own bodies when viewed from a first-person perspective compared to when viewed from an outside perspective. They did this by creating three virtual bodies ('avatars') for each participant. Participants rated their own body as more attractive when viewing it from a third-person perspective in virtual reality and showed that our internal representation of our own body shape is highly inaccurate.
