Bird population declines and species turnover are changing the acoustic properties of spring soundscapes

Catriona Morrison et al. show that the soundscape of birdsong in North America and Europe is becoming quieter and less varied, mirroring declines in bird diversity and abundance.

  • Manipulating photon dynamics is becoming increasingly important especially for quantum optics applications. In this work, the authors provide a mechanism that functions as a ‘photon brake’ which relies on the concept of temporal loss boundary to manipulate the dynamics of cavity photons.

  • Direct transfer of pre-patterned materials strongly benefits realisation of integrated functional systems over conventional fabrication process. Here, the authors demonstrate a self-delamination-driven pattern transfer of a single crystalline silicon thin membrane via well-controlled interfacial design in a liquid media.

  • Optical manipulation of large objects is challenging as optical trap positions are blindly chosen. Here, the authors present off-focus interferometric tracking, which localises optimal grabbing positions with increased refractive index, by analysing the beam deformations of several holographic optical traps.

  • Starch is the major form of energy storage in plant cells and forms discrete, semi-crystalline granules within plastids. Here the authors use electron tomography and nanoSIMS to show that Arabidopsis starch granules initiate in stromal pockets between thylakoid membranes that coalesce before growing anisotropically.

  • Microbial DNA glycosylases associated with the biosynthesis of DNA-damaging antibiotics have evolved self-resistance for their cognate natural products. Here, the authors provide evidence that cellular self-resistance is enabled by reduced affinity of the glycosylases for the excision products of the corresponding DNA lesions.

  • Developing more productive and sustainable crops will be essential to achieving food security in coming decades. A core process in plant evolution has been the transfer of chloroplast-encoded genes to the nuclear genome. We propose reverting this process as a new approach to improve plant disease resistance and photosynthesis in future crops.
