A trio of researchers at Kiel University in Germany has discovered how the male thistle tortoise beetle manages to penetrate the coiled duct inside the female reproductive organ without buckling his flagellum. In their paper ...
The evolution of hyperswarming, pathogenic bacteria might sound like the plot of a horror film, but such bugs really have repeatedly evolved in a lab, and the good news is that they should be less of a problem to us than ...
