About the cover

In this special issue on human migration, Nature investigates the facts behind the headlines on migration and speaks to refugee and immigrant scientists. Vivek Wadhwa celebrates the foreign-born entrepreneurs who have brought jobs and wealth to America. And Huub Dijstelbloem and Gemma Galdon Clavell highlight ethical issues around the increasing use of technology to track people’s movements. Cover art: Alberto Seveso

    The genomes of 102 primary pancreatic neuroendocrine tumours have been sequenced, revealing mutations in genes with functions such as chromatin remodelling, DNA damage repair, mTOR activation and telomere maintenance, and a greater-than-expected contribution from germ line mutations.

    X-ray detection of an ultrafast outflow of gas is strongly linked with energy emission from the inner accretion disk of a black hole, suggesting that X-rays ionize the outflowing disk wind.

    Nanometre-scale columnar structures in tooth enamel inspire novel nanocomposites containing layers of vertically aligned nanowires, produced by layer-by-layer fabrication and combining high values of both storage modulus and energy dissipation.

    Neurons that project from the prefrontal cortex to either the nucleus accumbens or paraventricular thalamus receive different inputs, differentially encode reward-predictive cues, and have opposing effects on reward seeking during cue presentation.

    Introducing chimeric antigen receptors into the endogenous T-cell receptor locus reduces tonic signalling, averts accelerated T-cell differentiation and delays T-cell exhaustion, leading to enhanced function and anti-tumour efficacy compared to random integrations.

    Circular extrachromosomal DNA is found in nearly half of human cancers of a wide variety of histologic types, increasing the copy number of driver oncogenes and intratumoral heterogeneity more effectively than chromosomal amplification and contributing to tumor evolution.

  • Untimely expression of gametogenic genes in vegetative cells causes uniparental disomy
