Focus on Neurovascular Interactions
Blood vessels in the nervous system are not simply neutral bystanders that only support the changing needs of neurons. This Focus from Nature Neuroscience discusses our emerging knowledge of how neurovascular interactions shape neuronal function both in health and disease.

This study demonstrates how two instances of such discrepancies can be resolved by taking advantage of an enotropic formulation of the uncertainty principle. | | | 17 Jan | Nat Commun 3:634 doi:10.1038/ncomms1631 (2012) | | | Physical sciences Theoretical physics | | | | Abstract | Full Text | PDF (393 kB) |

| ELL facilitates RNA polymerase II pause site entry and release OPEN | | | Jung S. Byun, Temesgen D. Fufa, Clay Wakano, Alfonso Fernandez, Cynthia M. Haggerty, Myong-Hee Sung and Kevin Gardner | | | The super elongation complex, which is involved in transcriptional elongation, contains the Eleven-nineteen Lysine-rich Leukemia protein (ELL). In this study, ELL is shown to stabilize RNA polymerase II prior to recruitment into the super elongation complex, suggesting ELL has a role in early transcription elongation. | | | 17 Jan | Nat Commun 3:633 doi:10.1038/ncomms1652 (2012) | | | Biological sciences Cell biology | | | | Abstract | Full Text | PDF (1,621 kB) |

| Propagation stability of self-reconstructing Bessel beams enables contrast-enhanced imaging in thick media | | | Florian O. Fahrbach and Alexander Rohrbach | | | Self-reconstructing laser beams can propagate deep into thick media, making them ideal for light-sheet microscopy of organic matter. By considering the rings of self-reconstructing Bessel beams, Fahrbach and Rohrbach present a technique for improving the contrast and resolution of this approach. | | | 17 Jan | Nat Commun 3:632 doi:10.1038/ncomms1646 (2012) | | | Physical sciences Applied physics | | | Optical physics | | Abstract | Full Text | PDF (1,516 kB) |

| A cobalt complex redox shuttle for dye-sensitized solar cells with high open-circuit potentials OPEN | | | Jun-Ho Yum, Etienne Baranoff, Florian Kessler, Thomas Moehl, Shahzada Ahmad, Takeru Bessho, Arianna Marchioro, Elham Ghadiri, Jacques-E. Moser, Chenyi Yi, Md. K. Nazeeruddin and Michael Grätzel | | | Dye-sensitized solar cells are a promising alternative to traditional inorganic semiconductor-based solar cells. Yum et al. use a molecularly engineered cobalt complex as a redox mediator to achieve an open-circuit voltage of over 1,000 mV in a mesoscopic dye-sensitized solar cell. | | | 17 Jan | Nat Commun 3:631 doi:10.1038/ncomms1655 (2012) | | | Chemical sciences Inorganic chemistry | | | Materials science Nanotechnology | | | Physical chemistry | | Abstract | Full Text | PDF (922 kB) |

| c-Src and IL-6 inhibit osteoblast differentiation and integrate IGFBP5 signalling | | | Barbara Peruzzi, Alfredo Cappariello, Andrea Del Fattore, Nadia Rucci, Fabrizio De Benedetti and Anna Teti | | | Osteoblast maturation is regulated by c-Src and IL-6, but how these signalling pathways are integrated is not known. Here c-Src is shown to induce 1GFBP5 in immature osteoblasts in a STAT3 and IL-6-dependent manner, in mature osteoblasts, which express lower levels of c-Src, this signalling is lost. | | | 17 Jan | Nat Commun 3:630 doi:10.1038/ncomms1651 (2012) | | | Biological sciences Cell biology Medical research | | Abstract | Full Text | PDF (1,339 kB) |

| Observation of the inverse spin Hall effect in silicon OPEN | | | Kazuya Ando and Eiji Saitoh | | | The spin Hall effect is a spin current induced by an electric current, and its occurrence in semiconductors is a promising route to controlling spins and their transport. Here, the inverse spin Hall effect, in which an electric current is induced by a spin current, is observed in silicon for the first time. | | | 17 Jan | Nat Commun 3:629 doi:10.1038/ncomms1640 (2012) | | | Physical sciences Condensed matter | | | Materials science | | | Abstract | Full Text | PDF (811 kB) |
| Electrically driven photon antibunching from a single molecule at room temperature | | | Maximilian Nothaft, Steffen Höhla, Fedor Jelezko, Norbert Frühauf, Jens Pflaum and Jörg Wrachtrup | | | Single-photon emitters are important for developing quantum technologies, but their integration with existing devices requires them to be driven by electric fields. Here, an organic light-emitting diode is presented that emits single photons from guest molecules in an applied electric field at room temperature. | | | 17 Jan | Nat Commun 3:628 doi:10.1038/ncomms1637 (2012) | | | Physical sciences Applied physics | | | Atomic and molecular physics Nanotechnology | | | Optical physics | | | Abstract | Full Text | PDF (724 kB) |
| Evidence for the late formation of hydrous asteroids from young meteoritic carbonates | | | Wataru Fujiya, Naoji Sugiura, Hideyuki Hotta, Koji Ichimura and Yuji Sano | | | Dating the age of meteorites can tell us when asteroids formed, but uncertainty remains in the Mn–Cr chronometry. This study presents a method for improving Mn/Cr determination and reports an age of 4,563.4 million years ago for carbonates in CM chondrites, which is younger than previous estimates. | | | 17 Jan | Nat Commun 3:627 doi:10.1038/ncomms1635 (2012) | | | Earth sciences Planetary sciences | | Abstract | Full Text | PDF (501 kB) |

| ABL1 regulates spindle orientation in adherent cells and mammalian skin OPEN | | | Shigeru Matsumura, Mayumi Hamasaki, Takuya Yamamoto, Miki Ebisuya, Mizuho Sato, Eisuke Nishida and Fumiko Toyoshima | | | A systematic approach for identifying the genes responsible for the regulation of spindle orientation in mammals has been lacking. Now, Matsumura et al. perform a kinase-targeting RNAi screen and identify ABL1, which through the direct phosphorylation of NuMa, is a novel regulator of spindle orientation. | | | 17 Jan | Nat Commun 3:626 doi:10.1038/ncomms1634 (2012) | | | Biological sciences Cell biology | | | Developmental biology | | | Molecular biology | | Abstract | Full Text | PDF (1,404 kB) |
