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.

By using different groups of cells to represent distinct environments and events, the dentate gyrus of the hippocampus helps to keep memories of similar events separate.

The plant hormone ethylene regulates the expression of multiple genes in the model plant Arabidopsis, including those that respond to other hormones.

A common mechanism might regulate the communal death of cells in flies and mammals.

Experiment-driven quantitative model of IL-2 secretion demonstrates how T cells integrate their digital antigen responses into an analog-scaled output.

The firing rates of neurons in the grasshopper auditory system are surprisingly robust to changes in temperature, and cell-intrinsic mechanisms are sufficient to explain this temperature insensitivity.

Three-dimensional mapping of the neural circuitry that controls movement of a marine worm in response to light provides insights into the evolution of complex visual systems.

Studying the earliest events in B cell activation reveals that the B cell antigen receptor is opened and activated via the phosphorylation and binding by the spleen tyrosine kinase (Syk).

Negative feedback signals within the substantia nigra regulate the output of the basal ganglia, with implications for disorders such as Parkinson's disease.

A new computational model of the Warburg Effect reveals that the rate-limiting step of glycolysis is variable, identifies new control mechanisms, and could help to predict the responses to targeting glycolysis to treat cancer.
