Re-engineering the zinc fingers of PRDM9 reverses hybrid sterility in mice p.171

PRDM9 is a DNA-binding protein that controls the position of double-strand breaks in meiosis, and the gene that encodes it is responsible for hybrid infertility between closely related mouse species; this hybrid infertility is eliminated by introducing the zinc-finger domain sequence from the human version of the PRDM9 gene, a change which alters both the position of double-strand breaks and the symmetry of PRDM9 binding and suggests that PRDM9 may have a more general but transient role in the early stages of speciation.

Schizophrenia risk from complex variation of complement component 4 p.177

Schizophrenia is associated with genetic variation at the major histocompatibility complex locus; this study reveals that alleles at this locus associate with schizophrenia in proportion to their tendency to generate greater expression of complement component 4 (C4A) genes and that C4 promotes the elimination of synapses.

Naturally occurring p16Ink4a-positive cells shorten healthy lifespan p.184

When senescent cells accumulate during adulthood they negatively influence lifespan and promote age-dependent changes in several organs; clearance of these cells delayed tumorigenesis in mice and attenuated age-related deterioration of several organs without overt side effects, suggesting that the therapeutic removal of senescent cells may be able to extend healthy lifespan.

Multistage coupling of independent laser-plasma accelerators p.190

Laser-plasma particle accelerators offer much higher acceleration than conventional methods, which could enable high-energy applications; here two separate accelerator stages, driven by two independent lasers, are coupled using plasma-based optics.

Observing the Rosensweig instability of a quantum ferrofluid p.194

Spontaneous translational symmetry breaking is experimentally observed in a dipolar Bose–Einstein condensate of dysprosium atoms, whereby an instability causes a spontaneous transition from an unstructured superfluid to an ordered arrangement of droplet crystals, which is surprisingly long-lived.

Observation of polar vortices in oxide superlattices p.198

In material systems with several interacting degrees of freedom, the complex interplay between these factors can give rise to exotic phases; now superlattices consisting of alternating layers of PbTiO3 and SrTiO3 are found to exhibit an unusual form of ferroelectric ordering in the PbTiO3 layers, in which the electric dipoles arrange themselves into regular, ordered arrays of vortex–antivortex structures.

Macromolecular diffractive imaging using imperfect crystals p.202

Crystal lattice disorder, which gives rise to a continuous diffraction pattern, is exploited to determine the structure of the integral membrane protein complex photosystem II to a higher resolution than could be achieved using Bragg diffraction alone.

Covariation of deep Southern Ocean oxygenation and atmospheric CO2 through the last ice age p.207

A reconstruction of changes in ocean oxygenation throughout the last glacial cycle shows that respired carbon was removed from the deep Southern Ocean during deglaciation and Antarctic warm events, consistent with a prominent role of reduced iron fertilization and enhanced ocean ventilation, modifying atmospheric carbon dioxide concentrations over the past 80,000 years.

Hoxb5 marks long-term haematopoietic stem cells and reveals a homogenous perivascular niche p.223

Until recently, complex multi-parameters were required for the isolation and identification of haematopoietic stem cells, complicating study of their biology in situ; here the authors have found that expression of a single gene, Hoxb5, defines haematopoietic stem cells with long-term reconstitution capacity, and that these cells are mainly found in direct contact with endothelial cells.

Real-time, portable genome sequencing for Ebola surveillance p.228

A nanopore DNA sequencer is used for real-time genomic surveillance of the Ebola virus epidemic in the field in Guinea; the authors demonstrate that it is possible to pack a genomic surveillance laboratory in a suitcase and transport it to the field for on-site virus sequencing, generating results within 24 hours of sample collection.

Backbone NMR reveals allosteric signal transduction networks in the β1-adrenergic receptor p.237

Although several X-ray crystal structures of G protein-coupled receptors (GPCRs) have been reported, relatively little is known about the conformational dynamics of these important membrane proteins; here, the authors used NMR spectroscopy to monitor the conformational changes that occur in the turkey β1-adrenergic receptor in the presence of antagonists, partial agonists, and full agonists.
