A golden binary p.36

The discovery of gravitational waves from a neutron-star merger and the detection of the event across the electromagnetic spectrum give insight into many aspects of gravity and astrophysics. See Letter p.64, p.67, p.71, p.75 & p.80

The surprising history of an antioxidant p.37

What came first: oxygen-producing photosynthesis, or compounds that protect cells from oxygen-induced damage? It emerges that one such compound might have been produced in microbes before Earth's oxygenation.

How to build a cohesive genome in 3D p.38

Removing the protein complex cohesin from chromosomes destroys one layer of the genome's 3D structure but leaves another intact. Genome structure is therefore built by independent processes that work together. See Letter p.51

Quarks fuse to release energy p.40

In nuclear fusion, energy is produced by the rearrangement of protons and neutrons. The discovery of an analogue of this process involving particles called quarks has implications for both nuclear and particle physics. See Letter p.89

A change of fate for nerve repair p.41

Schwann cells support neuronal signalling. The discovery that these cells become dramatically reprogrammed after nerve injury, adopting migratory characteristics that promote repair, highlights the plasticity of mature cell types.

No escape from the tangled bank p.42

Ecological interactions emerge spontaneously in an experimental study of bacterial populations cultured for 60,000 generations, and sustain rapid evolution by natural selection. See Letter p.45
