摘要：Pockels materials are notable for their strong electro-optic interaction and rapid response times and are therefore used extensively in optical communications. However, at cryogenic temperatures, Pockels coefficients are reduced in many materials optimized for room-temperature operation, which is a major hurdle for emerging quantum technologies. Here, we show that strontium titanate (SrTiO3) can be engineered to exhibit a Pockels coefficient of 345 picometers per volt at 20 hertz at cryogenic ...

摘要：Understanding how life is adapting to urban environments represents an important challenge in evolutionary biology. In this work, we investigate a widely cited example of urban adaptation, Culex pipiens form molestus, also known as the London Underground mosquito. Population genomic analysis of similar to 350 contemporary and historical samples counters the popular hypothesis that molestus originated belowground in London <200 years ago. Instead, we show that molestus first adapted to human en...

摘要：Telomerase is a ribonucleoprotein complex that elongates telomeric DNA, ensuring germline immortality. In this study, we identified the Caenorhabditis elegans telomerase RNA component 1 (terc-1), as the first known telomerase RNA expressed as an intronic long noncoding RNA (lncRNA), embedded in an intron of germline-up-regulated gene nmy-2. terc-1 undergoes splicing, polyadenylation, and nuclear RNA exosome-dependent maturation, stabilized by H/ACA small nucleolar ribonucleoproteins, thus co-o...

摘要：Shallow-water waves are a notable example of nonlinear hydrodynamics, giving rise to phenomena such as tsunamis and undular waves. These dynamics are typically studied in hundreds-of-meters-long wave flumes. In this work, we demonstrate a chip-scale wave flume, which exploits nanometer-thick superfluid helium films and optomechanical interactions to achieve nonlinearities surpassing those of extreme terrestrial flows. Measurements reveal wave steepening, shock fronts, and solitary wave fission...
