Super-resolution STED microscopy is demonstrated for the first time in the deeply embedded mouse hippocampus in vivo, revealing direct evidence for an unprecedentedly high level of synapse remodeling in a brain structure closely associated with memory processing.
Lysine mono- and di-methylation are two novel post-translational modifications of RNA polymerase II, which are enriched at promoters of active genes, precede lysine acetylation and mark early stages of transcription.
An unbiased genetic screen in Drosophila provides evidence for a direct link between glial Ca2+ 25 signaling and classical functions of glia in buffering external K+ as a mechanism to regulate neuronal excitability.
As in humans, Drosophila hearts are able to maintain contractile performance during healthy aging, but this maintenance is associated with an increased susceptibility to progressive dysrhythmias that can lead to fibrillatory arrest.
The first genomic view of beetle luciferase evolution indicates evolutionary independence of luciferase between fireflies and click-beetles, and provide valuable datasets which will accelerate the discovery of new biotechnological tools.
