A few months old here but there is a very interesting post from the Science Media Centre in New Zealand: Science Media Centre: Microbes in soil could help fight crime. The post describes attempts to use microbes in soil as part of forensic activities. This relates in many ways to my call for a “Field Guide to Microbes”.
I have been interested in microbial forensics for many years since I worked at TIGR on part of the project to study anthrax genomes. For those interested in microbe-related forensic activities I have created a Mendeley collection of references on the topic.
