| Bright e-Paper by transport of ink through a white electrofluidic imaging film | | | M. Hagedon, S. Yang, A. Russell and J. Heikenfeld | | | Electronic paper technology is used in displays of portable electronic devices for its low-power consumption; however, it suffers from a sub-optimal reflectance. Hagedon et al. fabricate an electrofluidic film that allows video-rate switching and magazine-quality reflectance in electronic paper. | | | 06 Nov | Nat Commun 3:1173 doi:10.1038/ncomms2175 (2012) | | | Physical sciences Applied physics | | | | | Abstract | Full Text | PDF (1,853 kB) |
| Opposing regulation of dopaminergic activity and exploratory motor behavior by forebrain and brainstem cholinergic circuits | | | Jyoti C. Patel, Elsa Rossignol, Margaret E. Rice and Robert P. Machold | | | Dopaminergic circuits are implicated in exploratory motor behaviour and are modulated by acetylcholine. Using transgenic mouse models, Patel et al. find that loss of forebrain acetylcholine results in exaggerated dopamine efflux and hyperactivity, whereas loss of brainstem acetylcholine leads to hypoactivity. | | | 06 Nov | Nat Commun 3:1172 doi:10.1038/ncomms2144 (2012) | | | Biological sciences Neuroscience | | | Abstract | Full Text | PDF (2,483 kB) |

Geffrin et al. present unambiguous evidence of such scattering effects in the gigahertz range for a sub-wavelength dielectric sphere. | | | 06 Nov | Nat Commun 3:1171 doi:10.1038/ncomms2167 (2012) | | | Physical sciences Optical physics Nanotechnology | | | | Abstract | Full Text | PDF (1,436 kB) |

| Carrier multiplication in semiconductor nanocrystals detected by energy transfer to organic dye molecules OPEN | | | Jun Xiao, Ying Wang, Zheng Hua, Xiaoyong Wang, Chunfeng Zhang and Min Xiao | | | In semiconductors, an absorbed photon can generate multiple electron-hole pairs, but measurements of this carrier multiplication efficiency in nanocrystals need to correctly account for charged excitons. Xiao et al. meet this need by measuring energy transfer of biexcitons from nanocrystals to acceptor dyes. | | | 06 Nov | Nat Commun 3:1170 doi:10.1038/ncomms2183 (2012) | | | Physical sciences Materials science | | | Optical physics | | Abstract | Full Text | PDF (1,019 kB) |

Chapman | | | Theoretical models usually fail in describing the behaviour of a many-body quantum system at a hyperbolic fixed point—a point of unstable equilibrium analogous to a motionless inverted pendulum. Gerving et al. show that such behaviour can be explored in the non-equilibrium dynamics of a Bose condensate. | | | 06 Nov | Nat Commun 3:1169 doi:10.1038/ncomms2179 (2012) | | | Physical sciences Atomic and molecular physics | | | Condensed matter | | Abstract | Full Text | PDF (1,351 kB) |

| Sos-mediated cross-activation of wild-type Ras by oncogenic Ras is essential for tumorigenesis | | | Hao-Hsuan Jeng, Laura J Taylor and Dafna Bar-Sagi | | | The ras family of oncogenes consists of H-ras, K-ras and N-ras, and usually only one of these genes is mutated in a given tumour type. In this study, K-ras is found to promote the activation of wild-type H-ras and N-ras in a manner dependent on the Ras guanine nucleotide exchange factor Son of sevenless. | | | 06 Nov | Nat Commun 3:1168 doi:10.1038/ncomms2173 (2012) | | | Biological sciences Cancer | | | Cell biology | | Abstract | Full Text | PDF (822 kB) |

| Lithium–sulphur batteries with a microporous carbon paper as a bifunctional interlayer | | | Yu-Sheng Su and Arumugam Manthiram | | | The practical performance of lithium sulphide batteries is much less than their predicted performance because redox products dissolve over time. Su and Manthiram show that microporous carbon membranes inserted between cathode and separator localize soluble polysulphide species and improve battery cycling characteristics. | | | 06 Nov | Nat Commun 3:1166 doi:10.1038/ncomms2163 (2012) | | | Chemical sciences Physical chemistry | | | | | Abstract | Full Text | PDF (1,650 kB) |
