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.

Electron microscopy has been used to produce the first three-dimensional image of the PRC2 gene-silencing complex.

A combination of advanced optical imaging and cryogenic electron microscopy has been used to explore membrane fusion in a synthetic system and provide new insights into neurotransmitter release.

Eve Marder explains why all scientists should spend time living and working in a foreign country.

Simulations and experiments on systems containing two different populations of microorganisms show that interactions that benefit at least one of the populations can lead to communities with stable compositions, and that strong cooperation between two populations can lead to communities in which both populations are mixed together.

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

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.

Long-lived intermediate states formed by glycoprotein catalysts are an essential part of the process used by influenza virus particles to infect cells.
