Catalytic hotspots get noisy p.34

Identifying and imaging catalytically active sites on solid surfaces is a grand challenge for science. A microscopy technique has been developed that images 'noise' to detect active sites with nanometre-scale resolution. See Letter p.74

Sexual attraction channelled in moss p.35

An analysis reveals that both sexual reproduction and early-embryo development in the moss Physcomitrella patens are controlled by cellular calcium influxes through ion-channel proteins. See Letter p.91

Pulley protection in batteries p.37

High-energy battery electrodes can break apart during operation. Conventional rope-and-pulley systems have inspired the development of a polymer that holds electrodes together at the molecular scale, enabling durable batteries to be made.

Rhino gives voice to silent chromatin p.38

Flies use master lists of DNA sequences from transposons to identify and silence these virus-like, genomic parasites. How the lists themselves escape the fate of their transposon targets has now been solved. See Letter p.54

The next best thing p.39

A patient's tumour cells can be transplanted into a mouse to provide a model for analysis and drug testing. A panel of paediatric solid tumour models has been extensively characterized and made freely available. See Letter p.96

Quantum signals could soon span the globe p.41

Quantum communication offers many advantages over classical methods, but it has been limited to sending signals across a few hundred kilometres. Two studies overcome this limitation. See Article p.43 & Letter p.70

Ground-to-satellite quantum teleportation p.70

Quantum teleportation of single-photon qubits from a ground observatory to a satellite in low-Earth orbit via an uplink channel is achieved with a fidelity that is well above the classical limit.

A series of energetic metal pentazolate hydrates p.78

Metal complexes of the pentazole anion exhibit multiple coordination modes, through ionic, covalent and hydrogen-bonding interactions, and good thermal stability with onset decomposition temperatures greater than 100 °C.

Island biogeography of marine organisms p.82

On marine islands, most species are good dispersers and most niches are filled by immigration with little adaptive radiation; speciation increases over time, associated with the arrival of weak dispersers that randomly establish isolated populations.
