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

Histones bound to lipid droplets inside cells offer protection against bacteria in flies, and possibly mice, thus suggesting a possible new innate immunity pathway.

The transcription machinery used to regulate gene expression and self-renewal in human embryonic stem cells is different from that found in other cells.

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.

A transmembrane protein uses distinct mechanisms to regulate the movement of specific toll-like receptors-key immune system components involved in detecting pathogens-to their final locations inside cells.
