The colony-forming choanoflagellate Salpingoeca rosetta is capable of moving towards oxygen using logarithmic sensing of oxygen concentrations and a navigation strategy that involves random movements.
Cooperativity between two transcription regulators occurs through protein-protein interactions with a general transcription factor complex and potentiates the parallel evolution of their DNA binding sites.
Discovery of the structural basis for recognition and uptake of a human precursor for body odour production reveals an important role for bacterial peptide transport and novel routes to prevent its production in humans.
The substrate for evolutionary divergence does not lie in changes in neuronal cell number or targeting, but rather in sensory perception and synaptic partner choice within invariant, prepatterned neuronal processes.
Identification and functional characterization of C. elegans luqin-like arginine-tyrosine-NH2 (RYamide) peptides reveal their critical role in feeding-related processes.
