About the cover

The cover shows the larva of a zebrafish (Danio rerio). In this issue, Florian Engert and his colleagues offer insight into the sensory system that allows fish to detect the flow of the water in which they swim. In a behaviour known as rheotaxis, fish consistently manage to orient and swim against oncoming currents, even when they lack any visual cues. The authors investigated this ability in larval zebrafish, and found that the secret is a series of hair cells — shown in red — known as the lateral line. They propose that these hair cells are used to estimate flow direction by detecting the rotation of local flow fields around the fish body. In the wild, this would enable the fish to navigate in environments that lack visual cues. Cover illustration: Julia Kuhl; zebrafish image: Robert Kasper & Pablo Oteiza

    In vivo CRISPR screening reveals that loss of Ptpn2 increases the response of tumour cells to immunotherapy and increases IFNγ signalling, suggesting that PTPN2 inhibition may potentiate the effect of immunotherapies that invoke an IFNγ response.

    The prompt optical flash produced by the γ-ray burst GRB 160625B is highly linearly polarized, suggesting that it is produced by fast-cooling synchrotron radiation in a large-scale magnetic field.

    Deforestation increases the odds of a species being threatened by extinction, and this effect is disproportionately strong in relatively intact landscapes, suggesting that efforts are needed to protect intact forest landscapes and prevent a new wave of extinctions.

    The cysteine protease CPR-4, a cathepsin B homologue, is identified as a radiation-induced bystander effect (RIBE) factor in nematodes in response to ultraviolet or ionizing radiation, and causes inhibition of cell death and increased embryonic lethality.

  • Unique roles for histone H3K9me states in RNAi and heritable silencing of transcription

    Heterochromatin formation involves histone H3 methylation, with H3K9me2 defining a distinct heterochromatin state that is transcriptionally permissive and can couple with RNAi, and the transition to non-permissive H3K9me3 required for the epigenetic heritability of heterochromatin.
