Fate and freedom in developing neocortical circuits OPEN
Denis Jabaudon
Proper functioning of the neocortex – the center of higher-order brain functions – depends on the correct assembly of neocortical neural circuits during development. Here the author discusses how cell-intrinsic developmental programs and activity-dependent signals together shape the formation of neocortical circuits.

Eco-evolutionary dynamics in a contemporary human population OPEN
Fanie Pelletier, Gabriel Pigeon, Patrick Bergeron, Francine M. Mayer, Mireille Boisvert, Denis Réale and Emmanuel Milot
Evolution can occur rapidly enough to influence population growth, though this possibility tends to be discounted for human populations. Here, the authors analyse genealogical records and show that evolution of women’s age at first reproduction contributed significantly to the growth of the île aux Coudres population.

Cosimo Posth, Christoph Wißing, Keiko Kitagawa, Luca Pagani, Laura van Holstein, Fernando Racimo, Kurt Wehrberger, Nicholas J. Conard, Claus Joachim Kind, Hervé Bocherens and Johannes Krause
Ancient DNA keeps expanding our understanding of complex genetic relationships between Pleistocene hominins. Here, Posth and colleagues analyse the mitochondrial genome of an archaic human that diverged from other Neanderthals ∼270,000 years ago, providing the minimum age for an African introgression into Neanderthals.

The biogenesis of AMPA-type glutamate receptor (AMPAR) complexes is only partially understood. Here the authors identify transient assemblies of GluA1-4 proteins and proteins FRRS1l/CPT1c that drive formation of mature AMPAR complexes in the ER. Mutations in FRRS1l are associated with intellectual disability and epilepsy in three families.

The evolution of host-symbiont dependence OPEN
Roberta M. Fisher, Lee M. Henry, Charlie K. Cornwallis, E. Toby Kiers and Stuart A. West
Hosts vary in how dependent they are on their beneficial symbionts. Here, Fisher and colleagues analyse the results of symbiont-removal experiments from 106 symbioses in a phylogenetic context and show that host dependence is associated with symbiont transmission mode, function, and genome size.
04 July 2017 | doi: 10.1038/ncomms15973

Munemasa Mori, Renin Hazan, Paul S. Danielian, John E. Mahoney, Huijun Li, Jining Lu, Emily S. Miller, Xueliang Zhu, Jacqueline A. Lees and Wellington V. Cardoso
Multiciliogenesis requires activation of transcriptional and protein assembly programs; however, the mechanisms that initiate the formation of these multiprotein complexes are unclear. Here the authors show that after inducing centriole biogenesis genes, the transcription factor E2f4 is required in the cytoplasm for assembly and nucleation of deuterosomes.

Cindy Kunze, Martin Bommer, Wilfred R. Hagen, Marie Uksa, Holger Dobbek, Torsten Schubert and Gabriele Diekert
Cobalamin-containing reductive dehalogenases from organohalide-respiring bacteria play a key role in the degradation of halogenated organic compounds. Here the authors proposed a catalytic mechanism for dehalogenation that relies on a long-range electron transfer from the cobalt in the centre of the enzyme’s cofactor to the substrate.

Jeremy Weaver, Mengqiu Jiang, Andrew Roth, Jason Puchalla, Junjie Zhang and Hays S. Rye
In the prevailing model for assisted protein folding, chaperonins act passively by preventing protein aggregation. Here, the authors use single-molecule fluorescence measurements and cryo-electron microscopy and show that the E. coli GroELS chaperonin system also has an active role in folding the endogenous bacterial protein PepQ.

Damage tolerance of nuclear graphite at elevated temperatures OPEN
Dong Liu, Bernd Gludovatz, Harold S. Barnard, Martin Kuball and Robert O. Ritchie
Nuclear-grade graphite is an important high-temperature structural material for fission reactors. Here, the authors perform simultaneous X-ray tomography and mechanical testing on a nuclear-grade graphite, finding simultaneous improvement of strength and toughness at elevated temperatures which they attribute primarily to reduction of residual tensile stresses in the as-made material.

MacMicking, Ramnik J. Xavier et al.
Prolonged NOD2 ligand engagement induces tolerance and attenuated NOD2 signalling, but the molecular mechanisms leading to this tolerance induction are unclear. Here the authors show that the degradation of a NOD2 adaptor, RIP2, by the E3 ligase ZNRF4 is essential for the down-regulation of NOD2 signalling.

The vascular stem cell niche regulates the proliferation and differentiation of neural stem cells (NSCs) in the adult subventricular zone. Here the authors identify EGFL7 as a neurovascular regulator of NSCs in vivo; EGFL7-knockout mice show reduced neurogenesis, and exhibit impaired olfactory perception and behaviour.

Negative regulation of EGFR signalling by the human folliculin tumour suppressor protein OPEN
Laura A. Laviolette, Julien Mermoud, Isabel A. Calvo, Nicholas Olson, Myriam Boukhali, Ortrud K. Steinlein, Elisabeth Roider, Elke C. Sattler, Dachuan Huang, Bin Tean Teh, Mo Motamedi, Wilhelm Haas and Othon Iliopoulos
Folliculin is a known tumour suppressor but the molecular mechanisms behind this function are unclear. Here the authors show that Folliculin regulates EGFR signalling by modulating its Rab7a-dependent trafficking.

Aptazyme-embedded guide RNAs enable ligand-responsive genome editing and transcriptional activation OPEN
Weixin Tang, Johnny H. Hu and David R. Liu
CRISPR-Cas9 is a powerful technique for manipulating the human genome, however temporal and spatial control of activity would facilitate safer, more selective use. Here the authors incorporate aptazymes into guide RNAs to allow small molecule activation of CRISPR-Cas9.

Critical mingling and universal correlations in model binary active liquids OPEN
Nicolas Bain and Denis Bartolo
Self-driven particles can drive the system out of equilibrium without the help of external forces. Here Bain et al. develop a model for two groups of motile bodies targeting opposite directions and show that the system exhibits critical behaviour as a function of particle density.
28 June 2017 | doi: 10.1038/ncomms15969

Ensemble-averaged Rabi oscillations in a ferromagnetic CoFeB film OPEN
Amir Capua, Charles Rettner, See-Hun Yang, Timothy Phung and Stuart S. P. Parkin
External driving of Rabi oscillations is a first step in the coherent manipulation of spin systems. Here the authors use ultrafast optical pulses to produce classical Rabi oscillations in ferromagnetic CoFeB, enabling the exploration of coherent phenomena in dense ferromagnetic ensembles.
