TL;DR: It is shown that asymmetric environments can produce a spontaneous and unidirectional rotation of nanofabricated objects immersed in an active bacterial bath and highlights the technological implications of active matter’s ability to overcome the restrictions imposed by the second law of thermodynamics on equilibrium passive fluids.

TL;DR: A new iterative algorithm for obtaining optimal holograms targeted to the generation of arbitrary three dimensional structures of optical traps is proposed, leading to unprecedented efficiency and uniformity in trap light distributions.

TL;DR: In this paper, the velocity of nanometric acoustic waves in supercritical fluid argon at high pressures was determined by inelastic X-ray scattering and molecular dynamics simulations, showing that the supercritical region is actually divided into two regions that, although not connected by a first-order singularity, can be identified by different dynamical regimes: gas-like and liquid-like.

TL;DR: In this paper, the authors used inelastic x-ray scattering with millielectron volt energy resolution at the European Synchrotron Radiation Facility in Grenoble, France, to study highfrequency collective dynamics in disordered systems.
