A flesh eating fly, thought to be dead for the last 160 years, has been rediscovered. The bone skipper, Thyreophora cynophila, was thought to be extinct but was caught in traps in the Spanish woodlands. The full report is published in Systematic Entomology and you can read the news articles on the New Scientist blog, Zoologger, or on the BBC website.

Humans may have caught cerebral malaria from gorillas.
