  • Genetic variation in a neuropeptide signalling pathway regulates age-related declines in health in nematode worms. This discovery points to a mechanism that influences individual differences in ageing. See Article p.198

  • A silicon probe that is inserted into the mouse brain can precisely measure the activity of about 200 individual neurons simultaneously. This tool should improve our ability to study functional neuronal circuitry. See Letter p.232

  • An event that initially resembled an ordinary supernova explosion continued to erupt brightly for more than 600 days. Standard theoretical models cannot explain the event's properties. See Letter p.210

  • Circulation of the ocean's densest waters modulates millennial-scale shifts in climate. Contrary to conventional wisdom, a study finds that the shape of the sea floor constrains where these waters rise towards the surface. See Article p.181

  • The treatment of a patient affected by an incurable genetic skin disease demonstrates the efficacy, feasibility and safety of replacing almost the whole skin using genetically corrected stem cells. See Letter p.327

  • 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

  • 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.

  • 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.

  • Small-molecule organic dyes that fluoresce in the short-wave infrared region of the spectrum could improve the resolution of in vivo bioimaging methods. Such dyes have now been made by adapting those that fluoresce visible light.

  • The energy source that drives vesicle fusion with a target organelle in vivo has been unclear. It emerges that proteins that tether fusing structures together also decrease the energy needed for the final fusion step. See Letter p.634

  • A large-scale study has been assessing microbial diversity by analysing DNA sequences from samples submitted by scientists around the globe. The initial results are now being used to create an open-access resource. See Article p.457

  • Modification of messenger RNAs through a process called m6A methylation facilitates dynamic temporal regulation of RNA levels in neural precursor cells, enabling fine-tuning of developing neuronal circuits in the brain.

  • Immunotherapy can reawaken T cells to destroy tumour cells. Modelling of tumour and T-cell interactions suggests why certain tumour cells are targeted and improves predictions of immunotherapy outcome.

  • Carbon–hydrogen bonds in organic molecules can be cut to install other chemical groups on the carbon atom, but these reactions have been limited. A catalytic palladium complex opens up fresh opportunities.

  • The peptide-loading complex is key to the initiation of an immune response that raises killer T cells in vertebrates. Its structure has now been determined, and might provide information that improves immune protection.
