Mirrors made of a single atomic layer p.177

Researchers have demonstrated that atomically thin materials can be highly reflective, contrary to general thinking. This finding could have technological implications for nanophotonics, optoelectronics and quantum optics.

Peptide signal alerts plants to drought p.178

It is thought that plants sense water availability in the soil as a way of anticipating drought. The identification of a peptide expressed when water is scarce offers a chance to unravel the underlying molecular mechanism.

The telomerase enzyme and liver renewal p.181

Cell-tracing analysis reveals that a disperse group of cells in the mouse liver express the enzyme telomerase, which preserves chromosome ends. These cells contribute to liver maintenance and regeneration.

Backbone of RNA viruses uncovered p.182

The evolutionary history of viruses is largely unknown. Large-scale discovery of vertebrate RNA viruses shows that, although viruses often jump between hosts, most have co-evolved with their hosts over millions of years

The evolutionary history of vertebrate RNA viruses p.197

Around 200 new vertebrate-specific viruses are discovered, and every vertebrate-specific viral family known to infect mammals and birds is also present in amphibians, reptiles or fish, suggesting that evolution of vertebrate viruses mirrors that of vertebrate hosts.

Cryo-EM structure of the Blastochloris viridis LH1–RC complex at 2.9 Å p.203

A cryo-electron microscopy structure of the light-harvesting–reaction centre (LH1–RC) complex of the photosynthetic bacterium Blastochloris viridis suggests factors that underlie the large redshift in the absorption spectrum of bacteriochlorophyll in the complex and that promote quinone–quinol translocation across the LH1 ring.

Crystal structures of the gastric proton pump p.214

Crystal structures of the gastric proton pump in complex with two inhibitory drugs reveal the mechanism that generates the steep acidic gradient across the membranes of parietal cells.
