Pink Grasshopper

Andrew Gable has a posting on his blog about a rare mutation of a grasshopper found in the UK. I've seen records of pink katydids here in the US; that might make an interesting book, Mutants in the Insect Kingdom.

Bar Coding Life

A cautionary note has been published, suggesting that those involved in creating "DNA bar codes" need to be very careful in their techniques to accurately choose the correct marker from the mitochondria, rather than non-functional copies from the nucleus. Inaccuracy could lead to mistaken "new species." (Eurekalert.)
