Comparative analysis of microexons across bilaterians identifies a new protein domain associated with the evolutionary origin of microexon inclusion in neural tissues.
A game theory study supported by in vitro experimental data shows that drug treatment of non-small-cell lung cancer cells causes the cells to switch between evolutionary games they play among each other. Moreover, the work calls into question standard assumptions on the fitness costs of drug resistance to cancer cells.
A survey of 16S rRNA sequences of the skin microbiomes of amphibians across the globe reveals links between climate and species richness as well as potential bacterial gene functions. The work paves the way for mechanistic studies of how the environment affects microbial community assembly.
A modelling study suggests that the ecology of host co-colonisation may play a key role in shaping population-level frequencies of antibiotic resistance in commensal bacteria.
The importance of biodiversity for productive community functioning is emerging as one of a very few general rules in ecology, but evidence has been sparse that it applies in tropical coral reefs—until now.
Radiocarbon dates from Spain put anatomically modern humans in southernmost Europe 10,000 years earlier than previously thought, diminishing the case for late survival of Neanderthals in the region.
Two soil respiration studies conducted at different spatial and temporal extents each find evidence that thermal adaptation of microbial communities compensates for loss of soil carbon under idealized conditions.
Influenza viruses undergo rapid antigenic evolution. Analysis of a large dataset of influenza virus sequences, using host age as a proxy for immune experience, shows no evidence for immune positive selection driving antigenic evolution in individual infected humans.
