Sequencing of the human body louse genome

The results of the sequencing and analysis of the human body louse genome offer new insights into the intriguing biology of this disease-vector insect.



Competition puts the brakes on body evolution

Often mistaken for chameleons or geckos, Anolis lizards fight fiercely for resources, responding to rivals by doing push-ups and puffing out their throat pouches. But anoles also compete in ways that shape their bodies over evolutionary time, says a new study.
