This week's picks
Prosocial preferences do not explain human cooperation in public-goods games "an increased awareness of how cooperation benefits others leads to a reduction, rather than an increase, in the level of cooperation"
Mutation in CSA creates a new photoperiod-sensitive genic male sterile line applicable for hybrid rice seed production "male sterility under short-day conditions and male fertility under long-day conditions"
Mutation rate dynamics in a bacterial population reflect tension between adaptation and genetic load "an adapting Escherichia coli population that first evolved a mutT hypermutator phenotype was later invaded by two independent lineages with mutY mutations that reduced genome-wide mutation rates"
Birth-death skyline plot reveals temporal changes of epidemic spread in HIV and hepatitis C virus (HCV) "Bayesian birth-death skyline plot, which explicitly estimates the rate of transmission, recovery, and sampling and thus allows inference of the effective reproductive number directly from genetic data."
Stable transgenesis in the marine annelid Platynereis dumerilii sheds new light on photoreceptor evolution "decapitated animals display a clear photoavoidance response"
Evidence for hydrogen oxidation and metabolic plasticity in widespread deep-sea sulfur-oxidizing bacteria "microbial chemosynthesis is also surprisingly pervasive throughout the dark oceans, serving as a significant CO2 sink even at sites far removed from vents"
Chytrid fungus Batrachochytrium dendrobatidis has nonamphibian hosts and releases chemicals that cause pathology in the absence of infection "B. dendrobatidis prevalence in crayfish was up to 29%, and that crayfish presence in Colorado wetlands was a positive predictor of B. dendrobatidis infections in cooccurring amphibians"
