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.

The development of colonies of cells in choanoflagellates, water-dwelling organisms that feed on bacteria, is triggered by the presence of very low concentrations of a lipid molecule produced by certain types of bacteria.

Biochemical and genetic tests have revealed that a liver protein called NTCP is a functional receptor for hepatitis B and D viruses, which should lead to an improved understanding of the infections caused by these viruses and assist the development of new intervention strategies.

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.

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.

A bacterial protein can be programmed with short RNA molecules to stimulate genome editing at specific sites in human cells.

Individual granule cells within the cerebellum-the region of the brain that coordinates movement and supports the learning of new motor skills-receive both sensory and motor input streams: an arrangement that may help the brain to use feedback to fine-tune movement.

The use of tissue culture reduces the chemical modification of plant DNA, and this has lasting effects on gene expression in the plants and their descendants.
