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 combination of advanced optical imaging and cryogenic electron microscopy has been used to explore membrane fusion in a synthetic system and provide new insights into neurotransmitter release.
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.
Similarities in the way that nucleosomes are organized into chromatin in archaea and eukaryotes suggest that chromatin might have been involved in gene regulation before its role in DNA packaging evolved.
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.
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.
