A combination of detailed sampling and mathematical modeling suggests that the response of immune cells to reactivation of herpes simplex virus 2 is extremely rapid and effective within microscopic areas of genital skin.
The ability of Manduca moths to recognize changes in the profile of volatile compounds released by plants being attacked by Manduca caterpillars allows them to lay their eggs on plants that are less likely to be attacked by insects and other predators, and to avoid competing against other caterpillars of the same species for resources.
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.
Experiments with realistic acoustic stimuli have revealed that humans distinguish salient sounds from background noise by integrating frequency and temporal information.
Skin cells from a patient with retinitis pigmentosa have been used to generate induced pluripotent stem cells, which could potentially form the basis of new treatments for this disease.

Computer simulations show that the firing patterns of branched touch receptors can be set in part by the organization of their sensory endings in the skin.
As mice learn to associate events separated in time, neurons within the CA1 region of the hippocampus progressively reorganize their firing patterns, leading to a relay of cellular activity that bridges the two events.
