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

A unique form of regulation has been observed in the unfolded protein response of S. pombe, along with a novel mechanism of post-transcriptional mRNA processing.

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

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

A chromatin boundary factor that is only active during early embryo development has been discovered in Drosophila.

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.

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

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