Molecular profiling of annelid myocytes reveals that the last common protostome-deuterostome ancestor already possessed a dual musculature, with visceral smooth muscles ensuring digestion and somatic striated muscles ensuring locomotion.

Bipedal footprints made 3.66 million years ago provide the clearest available evidence to date of the occurrence of marked body size variation in Australopithecus afarensis..

The socially exchanged fluid passed mouth-to-mouth during trophallaxis contains molecules that can influence development, potentially mediating communal control of colony phenotypes.

A small brain-derived lipid prevents bristle worms from entering maturation and death, challenging current views of hormone evolution and pesticide specificity.

Analysis of epidemiological data reveals that viral loads in newly HIV-1 infected individuals in Uganda have declined for two decades, and evolutionary modelling shows that attenuation of the virus explains this decline.

Comparative transcriptomic analysis reveals the molecular basis and evolution of herbivore-associated early defense signaling in Nicotiana.

During evolutionary progression of Alu-exons, repressive U-tracts buffer sudden gains in 3' splice site strength and prevent inclusion of cryptic exons.

The transcriptional response of human neurons to calcium ion signals shows evolutionary divergence from those responses elicited in mouse neurons, providing evidence in favour of using human systems to study neuronal responses to external stimuli.
