Reflecting its role as a core clock protein, deletion of the "frq" gene results in arrhythmicity, and in "Neurospora", the only function of FRQ is in the circadian clock. The "frq" gene can be activated from two distinct cis-acting sequences in its promoter, a distal site, the clock-box, used in the context of circadia...

The mechanism of the SBTS is similar to the Tn5 transposon system, however the enzyme and gene sequences are eukaryotic in nature as opposed to prokaryotic. The system's tranposase can act in "trans" as well as in "cis", allowing a diverse collection of transposon structures. The transposon itself is flanked by inverte...

Widespread interest in ptychography only started after the first demonstration of iterative phase-retrieval X-ray ptychography in 2007 at the Swiss Light Source (SLS). Progress at X-ray wavelengths was then quick. By 2010, the SLS had developed X-ray ptychotomography, now a major application of the technique. Thibault,...
