  • Mutagenic lesions such as those that give rise to cancer frequently segregate—unrepaired—during cell division, resulting in phasing of multiple alleles across generations of daughter cells and consequent tumour heterogeneity.

  • Oxide ion conductors are technologically relevant for applications in electrochemical devices such as sensors, separation membranes and fuel cells. Magnesium doping in Na0.5Bi0.5TiO3—a piezoelectric material that suffers from high leakage conductivity—now results in a family of ionic conductors that could prove significant not only for dielectric-based applications but also for intermediate-temperature solid-oxide fuel cells.

  • This Review discusses quantum optimization, focusing on the potential of exact, approximate and heuristic methods, core algorithmic building blocks, problem classes and benchmarking metrics. The challenges for quantum optimization are considered, and next steps are suggested for progress towards achieving quantum advantage.

  • A phylogenetic analysis of breeding behaviour in birds shows that cooperation is more likely when promiscuity is low — a circumstance in which helpers can be more certain that they are offering aid to relatives. Intermediate levels of promiscuity favour the ability to distinguish relatives from non-relatives. At high levels of promiscuity, no form of cooperation is favoured. Levels of promiscuity therefore provide an explanation for differences between species in levels of cooperation.
