An insect-like mushroom body in one group of crustaceans, the mantis shrimps (Stomatopoda), suggests either an ancient origin of this center and its reduction and loss in other crustaceans, or an extraordinary example of convergent evolution with the insect mushroom body.

Demonstrating extreme diversity across crustaceans while contrasting with evolutionary stability in insects, mushroom body homologues further underpin the unity of Pancrustacea and shed new light on arthropod brain evolution.

The first malacostracan genome sequence will establish the genetically tractable Parhyale hawaiensis as a model organism in this key animal group.

The insect odorant receptor gene family evolved at the base of the class Insecta before the evolution of flight and perhaps as an adaptation to terrestriality, and was therefore an important evolutionary novelty for insects.

During walking and turning, the fruit fly Drosophila uses variable limb coordination patterns, which exist on a low-dimensional, continuous manifold.

A newly discovered cytoplasmic intermediate filament in water bears may help these animals to resist extreme environmental conditions.

Insect specific olfactory receptors are not an adaptation to a terrestrial insect lifestyle, but evolved later in insect evolution.

Novel imaging experiments suggest that fruit flies modify their neural circuitry for walking at slow, medium and fast speeds, and that proprioception is not essential for coordinated walking.

To protect mammals against retroviral infections, TRIM5 restriction factors recognize viral capsids by forming complementary hexagonal nets that can adapt to the patterns of capsid protein subunits on the viral capsid surface.

Evolutionary dynamics of polyploid plants of the genus Cochlearia during past periods of rapid climate change indicate increased rates of speciation and diversification in response to pronounced glacial cycles and cold periods in particular.
