STRUCTURAL BIOLOGY

Insights into proteasome inhibition

High-resolution structures of human 20S proteasomes reveal chemical principles for next-generation drug design.

PLANT SCIENCE

Searching for the Sun

Sun-tracking when young, east-facing when mature, warmer sunflowers attract more pollinators.
