Nano-cleaners.
University of Colorado Boulder researchers have found that tiny, self-propelled particles can swim to escape from mazes as much as 20 times faster than passive particles, paving the way for their use in cleaning waste from hard to reach areas.
Their nanosystem is described in PNAS: http://dx.doi.org/10.1073/pnas.2101807118

Mechanisms of transport enhancement for self-propelled nanoswimmers in a porous matrix
As with living microorganisms, many real-world applications of synthetic micro/nanoswimmers are likely to rely on transport in complex environments, a phenomenon that remains poorly understood. Here, we report anomalously rapid transport of self-propelled…
Hawking’s black hole theorem - confirmed.
Hawking’s central law for black holes predicts that the area of their event horizons should never shrink. Physicists at MIT have confirmed Hawking's theorem using experimental observations of gravitational waves.
Their confirmation is published in Physical Review Letters: https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.127.011103

Testing the Black-Hole Area Law with GW150914
By comparing the sizes of black holes before and after a merger, researchers have tested Hawking's theorem on black hole areas.
