Research on humans and dogs reveals that the communities of microorganisms found on the skin, on the tongue and in the intestine are affected differently by age and cohabitation.

Single absorbed photons trigger adaptational mechanisms that help the retina maintain sensitivity across a wide range of background illumination.

The ability of an enzyme called XPD helicase to unwind the double helix is influenced by the DNA sequence and the availability of energy.

Cryo-electron microscopy has been used to provide a structural interpretation of the complete action cycle of release factor 3 during translation termination, which includes a coordinated sequence of interactions with a class-I release factor and the ribosome.

Computer simulations reveal that viral nucleic acids have an ideal structure for being packaged into outer protein shells called capsids.

The divergence of gene regulation during evolution in yeast traces phylogenetic distance with prominent changes being associated with changes in lifestyle and a whole genome duplication event.

A DNA transposon, or ‘jumping gene’, controls its amplification within a genome through a competition between the enzyme multimers that are responsible for its mobility.

Lysine-specific demethylase 1 (Lsd1) has an essential role during both the early and later stages of blood cell development.

The Botryllus schlosseri genome yields insights into the evolution of hematopoiesis.

C. elegans exhibits two distinct behavioural macro-states, active and quiet wakefulness, and protein kinase A regulates switching between these two states.
