Precision cosmology from future lensed gravitational wave and electromagnetic signals
Nature Communications, 2017 Gravitational wave sources can be used as cosmological probes through a direct distance luminosity relation. Here, the authors demonstrate that the time delay between lensed gravitational wave signals and their electromagnetic counterparts can reduce the

Bioinspired Twisted Artificial Muscles with Enhanced Performance for Underwater Applications
Advanced Science, EarlyView.A climbing plant‐inspired twisted artificial muscle (TAM) with a braided configuration and seal‐inspired thermal insulation enables high‐performance underwater actuation. Enhanced deformation, reduced heat dissipation, and rapid motion are validated through a bionic ray that exhibits straight and turning motions.
