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.

Pyro-sequencing of two genes involved in bacterial secondary metabolism provides new insights into the rich reservoir of biologically active small molecules found in environmental bacteria.

Data analysis of a large number of species indicates that a negative temperature-mass relationship is not common among species, which has been an ecological assumption for over a century.

Dubbed the 'green yeast', the model alga C. reinhardtii has profoundly advanced many areas of biology, but much remains to be learnt about its life in the wild.

Microbiomediversity favors further diversity in a positive feedback that is strongest in lower-diversity biomes but which plateaus as niches are increasingly filled in higher-diversity biomes.

X-ray imaging reveals well-preserved internal characters in mineralized arthropods from the Paleogene, urging the reexamination of previously neglected fossil collections.

The ancestor of all known jawed vertebrates possessed a maxilla and premaxilla and was similar in morphology to the 'maxillate placoderms' from China.

Contrary to the high absolute number of white-eyes in other parts of the world, the Indonesian archipelago is the center of phylogenetic diversity of this great speciator.

Flying squirrels may have originated earlier than previously thought and remained unchanged for almost 12 million years.

Genetic variance of adult human height shows a generally increasing trend across the birth-year cohorts but heritability estimates do not present any clear pattern of secular changes over a century.
