- Structural basis for strand-transfer inhibitor binding to HIV intasomes
Single-particle cryo–electron microscopy shows how inhibitors that bind the intasome may allow the development of better drugs against HIV.
- Tropical snake diversity collapses after widespread amphibian loss
The loss of amphibians caused by a fungal disease has decreased diversity and worsened body condition in a neotropical snake community.
Erratum
About The Cover
COVER A satiny parrot snake (Leptophis depressirostris) preys on a frog. Tropical snake diversity declined after a fungal pathogen led to mass mortality of amphibians, a key food source. Snakes are generally rare and difficult to detect, but researchers estimate a high probability that the snake community is now smaller and more homogeneous, with lower occurrence rates and poorer body conditions for many species. See page 814.
