In a minimalistic, generic model of competitive communities in which evolution is constrained by life-history trade-offs, stable biodiversity emerges with species adapted to different functional niches.
UV-reflective dragonfly wax is shown to consist of very long-chain methyl ketones and aldehydes, and a synthetic dragonfly wax spontaneously forms light-scattering fine structures with strong UV reflection.
An in-depth metagenomic analysis of possibly the most abundant and widespread microbial lineage in the surface ocean teases apart evolutionary processes that maintain its genomic heterogeneity and biogeography.
A 2-year field study has demonstrated that volatile compounds produced by plants when they are attacked by herbivores act as defenses by attracting predators to the herbivores and increasing the reproduction of the plants.
Computer simulations of the evolution of broadly neutralizing antibodies against HIV suggest that non-traditional pathways involving framework mutations which lead initially to increased antibody flexibility do occur, but can be avoided by appropriate vaccine design.
