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

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.

By using immune cells called dendritic cells to deliver drugs, it is possible to target and kill specific members of another class of immune cell, known as T cells, and to prevent these cells from attacking the body's own tissues in cases of autoimmune disease.

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.

The ability to share resources for the benefit of all members of a group may have driven ancient organisms to evolve from a unicellular to a multicellular state.

A lipid acts to promote the development of nematode worm larvae through activation of an enzyme complex called TORC1.

When a protein involved in DNA repair malfunctions, it can anneal RNA molecules to DNA molecules, creating hybrids that increase the frequency of mutations in the DNA.

Longevity in C. elegans is influenced not only by insulin/IGF-1 signalling, but also by CAMKII and calcineurin, acting on the same target, the transcription factor DAF-16.

α-SNAP mediated rearrangement of Stim1 and Orai1 molecules within CRAC channel clusters is required for store-operated calcium entry.
