The first survey of the complete morphologies of nerve endings in the skin of mice has revealed enormous structural diversity.

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.

Changing the order in which presynaptic and postsynaptic cells are repeatedly activated can change what a mammalian visual cortex neuron communicates to downstream neurons.

A sudden fall in the levels of the coenzyme NADPH within cells could have a central role in the process of aging.

Neurons in the hippocampus modulate the rates at which they fire, and the locations in which they fire, so as to encode the information that is central to forming memories about personal experiences.

A protein complex that enables cells to transport substances across their membranes, and that typically consists of four subunits, can also function as two hemicomplexes, each with two subunits.

The transport of proteins along flagellar microtubules generates the force that enables flagella to propel cells across surfaces.

A study that models the evolution of drug resistance in tumors reveals that drugs are more effective when given in combination than sequentially, and that cure is much more likely when the drugs target different pathways.

Cells that give rise to the infectious form of parasitic flatworms called schistosomes show similar patterns of gene expression to stem cells in free-living flatworms.
