Experiments in mice have shown than an enzyme that repairs broken DNA inside the nucleus also has a central role in the innate immune system because it is able to detect foreign DNA outside the nucleus.

The first survey of the complete morphologies of nerve endings in the skin of mice has revealed enormous structural diversity.

Sensory neurons in the olfactory system develop from two different regions of the ectoderm, the olfactory placode and the cranial neural crest, whereas sensory neurons within the eye and ear develop from just one region.

Some of the mutations that occur during influenza evolution can only be tolerated in conjunction with other mutations that increase the stability of a viral protein.

The divergence of gene regulation during evolution in yeast traces phylogenetic distance with prominent changes being associated with changes in lifestyle and a whole genome duplication event.

Structural and biochemical analysis of a protein called Ecp6, which is produced by a tomato fungus, reveals how the protein prevents plants from launching an immune response to the chitin in fungal cell walls.

A statistical model is able to predict patterns of gene expression output in Drosophila embryos using only the cellular concentrations of transcription factors as input.

The spindle assembly protein Bub3 recruits the checkpoint kinase Bub1 to kinetochores by binding to phosphorylated MELT repeats in the kinetochore subunit Knl1.

Steroid hormone receptors control the expression of their target genes through a digital on-off switch in individual cells, which leads to an analogue dose-response relationship at the level of the whole organism.

Melainabacteria, a candidate phylum related to Cyanobacteria, has been identified in gut and sediment samples by genomic analysis.
