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 protein that can recognize regions of DNA with a high proportion of unmethylated CpG dinucleotides, and then recruit polycomb group proteins to these CpG islands, has been identified.

Preventing premature interactions between microtubules and protein-based structures called kinetochores ensures that chromosomes are segregated by meiosis rather than mitosis in reproductive cells.

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.

Cleavage of a membrane-bound transcription factor by the chemotherapeutic reagent doxorubicin can block the proliferation of tumor cells.

A combination of cellular, biochemical, genetic and genomic techniques have revealed a new molecular player in the production of fat cells in mice, which could improve our understanding of obesity.

The HITS-CLIP sequencing method is used to demonstrate that cryptic exons can detect messenger RNA that contains nonsense mutations, and then cause this RNA to decay, which shows that these exons are involved in maintaining the electrical balance of neurons and, possibly, preventing epilepsy.
