Transgenic mice with high levels of FGF21 live for longer than wild-type mice and do so without reducing food intake.

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

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

Genome-wide measurements on mouse liver cells show that transcription, and a particular key transcription factor, have a smaller than expected influence on the mouse circadian system.

A mathematical model based on enzyme kinetics shows how the relationships between life expectancy, survival rates for children and adults, and national income change over time.

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.

A genome-organizing protein that is present only in the olfactory system of mice has been found to orchestrate changes in the relative numbers of different odor-sensing neurons on the basis of how active these neurons are.

A DNA–protein complex can find target sequences of bases in another DNA molecule by sliding along it.

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.
