I thought I knew what ACAB means

Walking from the msueum to my car I recently happened upon a trashcan in a public park. It had some grafitti on it, and lots of stickers. One read ACAB, which normally means All Cops Are Bastards. Not a sentiment … Continue reading

Interspecific prey theft in extant theropod dinosaurs – Ardea vs. Spheniscus

Golly, what a science journal-worthy title!
