    Here the authors show that a high-fat diet in pregnant mice can release silencing of the imprinted Dlk1 locus in multiple generations of offspring. They found that this occurs via changes in microRNA expression at the locus of interest, as well as transcriptional changes across the genome, in the developing oocytes.

    Conventional bioluminescence imaging usually operates in the visible region and its performance is limited by strong tissue absorption and scattering. Here, the authors present bioluminescence probes (BPs) with emission in the second near infrared (NIR-II) region, and show the NIR-II-BPs could sensitively recognize tumor metastasis with a high tumor-to-normal tissue ratio.

    Detection of amyloid beta deposits is often performed with fluorescent compounds that bind plaques. Here the authors develop turn-on chemiluminescent probes that bind amyloid beta plaques in vivo, and amplify the signal via chemiluminescence resonance energy transfer to the plaque-binding fluorescent molecule CRANAD-3.

    Dystrophin-deficient mice are used to test corrective strategies for Duchenne muscular dystrophy, but evaluation of dystrophin expression requires collection of tissue samples from specific muscles and time points. Here, the authors generate mice in which dystrophin expression is coupled to luciferase, and show that bioluminescence allows non-invasive monitoring of dystrophin expression following genome editing.

    Red-shifted bioluminescence emission is needed to improve deep tissue imaging resolution. Here, the authors develop a click beetle red luciferase mutant and two naphthyl-luciferin substrates, and show the ability of the new luciferin/luciferase pairing for deep tissue multispectral tomography in mice.

    G protein-coupled receptors are involved in numerous physiological functions, thus, they represent potential pharmaceutical targets. Here Kono et al. describe a new mouse model to image GPCR activation in real-time by exploiting firefly split luciferase fragment complementation that can be detected by bioluminescence imaging.

    The use of luminescence, rather than fluorescence, for imaging is advantageous in situations where laser illumination should be avoided. Here the authors make five colour variants of bright luminescent proteins based on FRET between NLuc and fluorescent proteins, and show their utility as Ca2+indicators.

    The coupling of optogenetics with fluorescent Ca2+ sensors is confounded by sensitivity of optogenetic probes to light used to excite the sensors. Here the authors develop a Ca2+ sensor based on bioluminescence resonance energy transfer (BRET) that monitors Ca2+fluxes in darkness without excitation.

    Cellular signaling processes often involve trafficking of receptors and other proteins between subcellular compartments. Here the authors demonstrate a method based on the concept of Enhanced bystander Bioluminescence Resonance Energy Transfer (EbBRET) that allows efficient real time monitoring of endocytosis and trafficking.

    Respiratory syncytial virus (RSV) causes severe respiratory disease in young children. Here, Rameix-Welti et al. create fluorescent and bioluminescent RSV strains that allow real-time analysis of viral replication and screening of antiviral compounds in cultured cells and in live animals.

    Mouse models of influenza infection that permit monitoring of infection in living animals are scarce. Here Pan et al. describe an engineered influenza virus expressing luciferase, which enables real-time in vivovisualization of viral infection and assessment of antiviral drugs.

    Luminescent proteins are important tools for biomedical imaging but tend to emit fairly little light. Saito et al.. describe a brighter version of a bioluminescent protein that can visualize intracellular dynamics of various signalling molecules with high spatial and temporal resolution.
