  • Sunlight harvesting and redirection is a promising concept for sustainable energy conversion, however losses have hindered progress. Here the authors construct a simple biomimetic device which minimises losses by using reservoirs of randomly-oriented dyes to funnel energy onto individual emitting parallel acceptors.

  • Synaptotagmin-1 (syt-1) triggers fast synchronous neurotransmission mediated by fusion of synaptic vesicles with presynaptic membranes. Here Lin et al. use inter-membrane FRET combined with DNA rulers as calibration standards to quantify Ca2+-induced changes in membrane distances mediated by syt-1.

  • Heterochromatin protein 1 (HP1), including HP1 α, β and γ, is a family of non-histone chromatin factors thought to be involved in chromatin organization. Here, the authors show that dimeric HP1β interacts dynamically with H3K9me3, a hallmark of heterochromatin, and bridges condensed chromatin.

  • Concentrations of cations and ATP affect the binding activities of synaptotagmin-1, to trigger synaptic vesicle exocytosis. In physiological ionic conditions, synaptotagmin-1's interaction with SNARE proteins is prevented, and its binding is confined to PIP2-containing membrane.
