This week's picks

Responses to the Assurance game in monkeys, apes, and humans using equivalent procedures "...only a subset of humans achieved these efficient outcomes, and pairs of both other species did so as well"

The origin and dynamic evolution of chemical information transfer
"chemicals are emitted, which can unintentionally provide information (cues) and... act as direct precursors for the evolution of intentional communication (signals)."
"In most cases, the excrements are cues, but the behavioural modulations... constitute signals helping to draw receivers' attention to the cues "
"males prefer flower bouquets to the sexual pheromone of local females, presumably because [the orchid] exploits pre-existing sensory biases of their pollinators"

Classic Selective Sweeps Were Rare in Recent Human Evolution
"amino acid and putative regulatory sites are not significantly enriched in alleles that are highly differentiated between populations"

Archaeal phylogenomics provides evidence in support of a methanogenic origin of the Archaea and a thaumarchaeal origin for the eukaryotes
"the Thaumarchaea (including Nitrosopumilis maritimus in our analysis) forms an independent group distinct from the Crenarchaea or Euryarchaea"

Footprints pull origin and diversification of dinosaur stem lineage deep into Early Triassic "...a few million years after the Permian/Triassic mass extinction (252.3 Ma)"

Optimal antiviral treatment strategies and the effects of resistance
"contrary to previous results, it is always optimal to treat at the maximum rate provided that this treatment occurs at the right time. "

Resolving the infection process reveals striking differences in the contribution of environment, genetics and phylogeny to host-parasite interactions
"transparent Daphnia hosts and fluorescently-labelled spores of the bacterium"
