The elaboration and diversification of sexually selected weapons remain poorly understood. We argue that progress in this topic has been hindered by a strong bias in sexual selection research, and a tendency for weapons to be conflated with ornaments used in mate choice. Here, we outline how male-male competition and female choice are distinct mechanisms of sexual selection, and why weapons and...

Response to comments on "Invasive harlequin ladybird carries biological weapons against native competitors".

We contend that there is abundant evidence that native ladybirds feed on H. axyridis eggs and that interspecific microsporidial transfer is a common phenomenon, supporting the proposed role of these parasites as biological weap...

Conventional kinesin has long been known to be a molecular motor that transports vesicular cargo, but only recently have we begun to understand how it functions in cells. Regulation of kinesin involves self-inhibition in which a head-to-tail interaction prevents microtubule binding. Although the mechanism of motor activation remains to be clarified, recent progress with respect to cargo binding...
