Virtual reality experiments show that motorists slow down when driving in fog, but they speed up when visibility is reduced equally at all distances.

Exposing rats to acute stress increased the generation of new neurons in a subregion of the hippocampus, and improved the animals' performance in a memory task two weeks later.

Imaging experiments reveal that some brain regions do not distinguish between actions performed using tools and those performed using the hands, while others represent these two types of action separately.

A compound that prevents stressors such as UV light and viral infection from downregulating protein synthesis inside cells improves memory performance in mice.

In a mouse model of neurodegeneration, hippocampal firing sequences that normally encode spatial memories become disengaged from external space.

Cryo-electron tomography reveals how a chaperone protein called TRiC reduces the ability of pathogenic mutant huntingtin proteins to form aggregates.

Experiments with realistic acoustic stimuli have revealed that humans distinguish salient sounds from background noise by integrating frequency and temporal information.

The use of metaphorical concepts is not unique to humans.

Rats show socially selective helping behavior based on familiarity with the type of rat, but not necessarily the individual rat.

Specific types of heterogeneity in the connectivity profile of a biological network give rise to dynamics with a hierarchy of localized temporal scales.
