Ultrasensitive detection of local acoustic vibrations at room temperature by plasmon-enhanced single-molecule fluorescence

.Sensitive detection of weak acoustic signals at nanometer scale is challenging. Here, the authors present an acoustic detection system based on a single molecule as a probe, where frequency and amplitude of acoustic vibrations can be extracted from its minute variations in distance to the surface of a plasmonic gold nanorod.

Novel polymer-free iridescent lamellar hydrogel for two-dimensional confined growth of ultrathin gold membranes

The structure of hydrogels is normally isotropic, but anisotropic hydrogels with a periodic lamellar structure can also be synthesized. Here the confined water layers in a lamellar hydrogel are used to guide the growth of large area, single-crystalline gold membranes with two-dimensional properties.

A new confuciusornithid bird with a secondary epiphyseal ossification reveals phylogenetic changes in confuciusornithid flight mode

A new species of Confuciusornis, a genus of basal birds from the Early Cretaceous, reveals that these early birds had stronger flight capability and more diverse flight modes than previously expected.
