A 2-year field study has demonstrated that volatile compounds produced by plants when they are attacked by herbivores act as defenses by attracting predators to the herbivores and increasing the reproduction of the plants.

Mathematical modeling shows that local populations of the malaria parasite self-organize into a limited number of transient but distinct strains through competition for hosts in immunity space.

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

Cauliflower mosaic virus reacts immediately when aphids feed on the host plant, and this boosts its chances of being taken up and transmitted by the insects to a new plant.

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 use of X-rays to investigate why bones break could lead to treatments that reduce the number of elderly people who suffer broken hips.

By using different groups of cells to represent distinct environments and events, the dentate gyrus of the hippocampus helps to keep memories of similar events separate.

A gene that codes for a transcription factor that is involved in lipid and carbohydrate metabolism also has a role in the regulation of circadian rhythms.

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.
