Protection and consolidation of stone heritage by self-inoculation with indigenous carbonatogenic bacterial communities OPEN
Fadwa Jroundi, Mara Schiro, Encarnación Ruiz-Agudo, Kerstin Elert, Inés Martín-Sánchez, María Teresa González-Muñoz & Carlos Rodriguez-Navarro

Salt weathering enhanced by global warming and environmental pollution is increasingly threatening stone monuments and artworks. Here, the authors present a bacterial self-inoculation approach with indigenous carbonatogenic bacteria and find that this technique consolidates and protects salt damaged stone.

Three-dimensional imaging of vortex structure in a ferroelectric nanoparticle driven by an electric field OPEN
D. Karpov, Z. Liu, T. dos Santos Rolo, R. Harder, P. V. Balachandran, D. Xue, T. Lookman & E. Fohtung

Imaging of topological states of matter such as vortex configurations has generally been limited to 2D surface effects. Here Karpov et al. study the volumetric structure and dynamics of a vortex core mediated by electric-field induced structural phase transition in a ferroelectric BaTiO3 nanoparticle.

The non-coding RNA BC1 regulates experience-dependent structural plasticity and learning OPEN

Brain cytoplasmic (BC1) RNA is a non-coding RNA that has been implicated in translational regulation, seizure, and anxiety. Here, the authors show that in the cortex, BC1 RNA is required for sensory deprivation-induced structural plasticity of dendritic spines, as well as for correct sensory learning and social behaviors.

Extrinsic mechanical forces mediate retrograde axon extension in a developing neuronal circuit OPEN
M. A. Breau, I. Bonnet, J. Stoufflet, J. Xie, S. De Castro & S. Schneider-Maunoury

How neuronal migration and axon growth coordinate during development is only partially understood. Here the authors use quantitative imaging to characterise the morphogenesis of the zebrafish olfactory placode and report an unexpected phenomenon, whereby axons extend through the passive movement of neuron cell bodies away from tethered axon tips.

Shift current photovoltaic effect in a ferroelectric charge-transfer complex OPEN
M. Nakamura, S. Horiuchi, F. Kagawa, N. Ogawa, T. Kurumaji, Y. Tokura & M. Kawasaki

The bulk photovoltaics refers to an effect whereby electrons move directionally in non-centrosymmetric crystals upon light radiation. Here, Nakamura et al. observe this effect in a ferroelectric organic charge-transfer complex, which shows large diffusion distance of photogenerated electrons over 200 µm.

Controlled radical fluorination of poly(meth)acrylic acids in aqueous solution OPEN
Yucheng Dong, Zhentao Wang & Chaozhong Li

Fluorinated alkenes have very poor reactivity in copolymerizations with non-fluorinated polar monomers. Here the authors show silver-catalyzed decarboxylative radical fluorination of poly(acrylic acid) with Selectfluor in water at room temperature to form poly(vinyl fluoride-co-acrylic acid) copolymers.

Liquid–liquid phase separation of the microtubule-binding repeats of the Alzheimer-related protein Tau OPEN
Susmitha Ambadipudi, Jacek Biernat, Dietmar Riedel, Eckhard Mandelkow & Markus Zweckstetter

Tau forms aggregates in the brains of Alzheimer patients. Here, the authors identify conditions, where the microtubule-binding repeats of Tau undergo a phosphorylation-dependent liquid–liquid phase separation, leading to molecular crowding in the formed Tau liquid droplets and characterize them by NMR and other biophysical methods.

Dendritic calcium spikes are clearly detectable at the cortical surface OPEN
Mototaka Suzuki & Matthew E. Larkum

Surface EEG recordings are thought to primarily detect synaptic activity. Here the authors devise an optogenetic method to evoke dendritic calcium spikes in layer 5 pyramidal cells of the rat somatosensory cortex, and report that optogenetically evoked, as well as sensory-evoked dendritic calcium spikes make a significant contribution to surface EEG recordings.

G9a regulates breast cancer growth by modulating iron homeostasis through the repression of ferroxidase hephaestin OPEN
Ya-fang Wang, Jie Zhang, Yi Su, Yan-yan Shen, Dong-xian Jiang, Ying-yong Hou, Mei-yu Geng, Jian Ding & Yi Chen

G9a is a histone methyltransferase highly expressed in several cancers including breast cancer. Here the authors propose a mechanism through which G9a promotes breast cancer by regulating iron metabolism through the repression of ferroxidase hephaestin.

Black phosphorus ink formulation for inkjet printing of optoelectronics and photonics OPEN

Atomically thin black phosphorus shows promise for optoelectronics and photonics, yet its instability under environmental conditions and the lack of well-established large-area synthesis protocols hinder its applications. Here, the authors demonstrate a stable black phosphorus ink suitable for printed ultrafast lasers and photodetectors.

The genetic basis of natural variation in a phoretic behavior OPEN
Daehan Lee, Heeseung Yang, Jun Kim, Shannon Brady, Stefan Zdraljevic, Mostafa Zamanian, Heekyeong Kim, Young-ki Paik, Leonid Kruglyak, Erik C. Andersen & Junho Lee

Nematodes use a characteristic set of movements, called nictation, to hitchhike on more mobile animals. Here, Lee et al. identify a genetic locus in the nematode Caenorhabditis elegans that underlies nictation and contributes to successful hitchhiking, but at expense of reduced offspring production.

Specialized odorant receptors in social insects that detect cuticular hydrocarbon cues and candidate pheromones OPEN
Gregory M. Pask, Jesse D. Slone, Jocelyn G. Millar, Prithwiraj Das, Jardel A. Moreira, Xiaofan Zhou, Jan Bello, Shelley L. Berger, Roberto Bonasio, Claude Desplan, Danny Reinberg, Jürgen Liebig, Laurence J. Zwiebel & Anandasankar Ray

Cuticular hydrocarbons (CHC) mediate the interactions between individuals in eusocial insects, but the sensory receptors for CHCs are unclear. Here the authors show that in ants such as H. saltator, the 9-exon subfamily of odorant receptors (HsOrs) responds to CHCs, and ectopic expression of HsOrs in Drosophila neurons imparts responsiveness to CHCs.
