Drosophila long-term memory formation involves regulation of cathepsin activity.

abstract：:Efficient long-distance quantum teleportation is crucial for quantum communication and quantum networking schemes. Here we describe the high-fidelity teleportation of photons over a distance of 600 metres across the River Danube in Vienna, with the optimal efficiency that can be achieved using linear optics. Our resul...

abstract：:Post-transcriptional gene regulation frequently occurs through elements in mRNA 3' untranslated regions (UTRs). Although crucial roles for 3'UTR-mediated gene regulation have been found in Caenorhabditis elegans, most C. elegans genes have lacked annotated 3'UTRs. Here we describe a high-throughput method for reliable...
