The authors inject mouse pluripotent stem cells into pancreatogenesis-disabled rat blastocysts and thereby generate rats with mouse pancreata from which the islets, when transplanted into mice, can provide a long-term cure for symptoms of diabetes, without continuous immunosuppression.

The application of genome-wide CRISPR–Cas9 screening coupled with a fluorescent reporter to interrogate the microRNA pathway reveals that continual transient phosphorylation of Argonaute 2 is required to maintain the global efficiency of microRNA-mediated repression.

The properties of pulsars in the globular cluster 47 Tucanae suggest that an intermediate-mass black hole is hidden in the cluster’s gas-starved central cavity.

Excitations to Rydberg states in a gas of ultracold atoms are used to produce a robust, nonlinear phase shift of exactly π/2 between two photons, which is protected against variations in experimental parameters by a symmetry of the system.

Cells in dense bacterial suspensions can self-organize into highly robust collective oscillatory motion, while individual cells move in an erratic manner; their interaction is modelled to reveal a weak synchronization mechanism.

Modelling of ocean carbon uptake for the 1980s to the 2000s shows that stronger upper-ocean overturning caused less carbon to be absorbed by the oceans in the 1990s, but that as the overturning circulation weakens more carbon is now being absorbed.

Removal of invasive exotic shrubs from mountaintop communities increased the number of pollinators and positively altered pollinator behaviour, which enhanced native fruit production, indicating that the degradation of ecosystem functions is partly reversible.

Coordinated gamma oscillations in the lateral hypothalamus, lateral septum and medial prefrontal cortex are shown to drive food-seeking behaviour in mice independently of nutritional need and to organize firing of feeding behaviour-related hypothalamic neurons.

Wild-type Drosophila epithelial cells outcompete proto-oncogenic cells through translocation of the ligand Sas to the wild-type–tumour cell interface, where it binds the PTP10D receptor of the tumour cell, initiating pro-apoptotic signalling.
