Using techniques by analogy with parity–time symmetry allows a combination of optical gain and loss in large-scale synthetic lattices, which can lead, for example, to such a lattice being invisible when viewed from one side.

The microbial communities in the human intestine vary between individuals, and this variation is greater in older people; here it is shown that diet is the main factor that drives microbiota variation, which correlates with health.

The fabrication of transistors using vertical, six-sided core–multishell indium gallium arsenide nanowires with an all-surrounding gate on a silicon substrate combines the advantages of a three-dimensional gate architecture with the high electron mobility of the III–V nanowires, drastically enhancing the on-state current and transconductance.
