Sheikin, K. Behnia, T. Terashima, S. Uji, T. Shibauchi and Y. Matsuda | | | Spin liquids are states of matter in which the constituent spins of a magnet are highly correlated yet fluctuate strongly down to millikelvin temperatures. Here the authors report torque magnetometry measurements of the Mott insulator EtMe3Sb[Pd(dmit)2]2 and find it displays an ungapped quantum spin liquid state. | | | 25 Sep | Nat Commun 3:1090 doi:10.1038/ncomms2082 (2012) | | | Physical sciences Condensed matter | | | | | Abstract | Full Text | PDF (518 kB) |
| Quasiparticles and Fermi liquid behaviour in an organic metal OPEN | | | T. Kiss, A. Chainani, H.M. Yamamoto, T. Miyazaki, T. Akimoto, T. Shimojima, K. Ishizaka, S. Watanabe, C.-T. Chen, A. Fukaya, R. Kato and S. Shin | | | The physical properties of organic metals have generally been described in terms of a highly correlated Luttinger liquid. Using angle-resolved photoelectron spectroscopy, Kiss et al. measure the Fermi surface of (BEDT-TTF)3Br(pBIB), and find that, in contrast to other systems, it can be described as a Fermi liquid. | | | 25 Sep | Nat Commun 3:1089 doi:10.1038/ncomms2079 (2012) | | | Physical sciences Condensed matter | | | Materials science Physical chemistry | | | Abstract | Full Text | PDF (590 kB) |
| Computational design of self-assembling register-specific collagen heterotrimers | | | Jorge A. Fallas and Jeffrey D. Hartgerink | | | The computational prediction of complex protein architectures has been used to design globular proteins, but the folding of collagen triple helices is difficult to predict. Here, a sequence-based scoring function for triple helix is developed and used to select sequences likely to self-assemble with high stability. | | | 25 Sep | Nat Commun 3:1087 doi:10.1038/ncomms2084 (2012) | | | Chemical sciences Organic chemistry | | | | Abstract | Full Text | PDF (790 kB) |

| A kinase inhibitor screen identifies small-molecule enhancers of reprogramming and iPS cell generation OPEN | | | Zhonghan Li and Tariq M. Rana | | | The efficiency of reprogramming somatic cells to induced pluripotent stem cells is low. To enhance reprogramming efficiency, Li and Rana used a chemical screen and identified several kinase inhibitors that enhance reprogramming, and show that blocking Aurora A, p38 and inositiol triphosphate 3-kinase signalling is important for this process. | | | 25 Sep | Nat Commun 3:1085 doi:10.1038/ncomms2059 (2012) | | | Biological sciences Cell biology | | | | Abstract | Full Text | PDF (1,710 kB) |

Madsen et al. devise a continuous scheme for modulated entangled states that is more tolerant to noise and loss than other protocols. | | | 25 Sep | Nat Commun 3:1083 doi:10.1038/ncomms2097 (2012) | | | Physical sciences Optical physics | | | | Abstract | Full Text | PDF (654 kB) |

| Thyroid hormone determines the start of the sensitive period of imprinting and primes later learning OPEN | | | Shinji Yamaguchi, Naoya Aoki, Takaaki Kitajima, Eiji Iikubo, Sachiko Katagiri, Toshiya Matsushima and Koichi J. Homma | | | Filial imprinting allows precocial birds to form social attachment to other animals or objects soon after hatching. Yamaguchi and colleagues investigate the mechanisms responsible for this, and find that thyroid hormones circulating in the plasma regulate the sensitive period during which imprinting occurs. | | | 25 Sep | Nat Commun 3:1081 doi:10.1038/ncomms2088 (2012) | | | Biological sciences Neuroscience | | Abstract | Full Text | PDF (1,044 kB) |

Henstridge, Olivier Lassalle, Daniela Neuhofer, Henry Martin, Melanie Ginger, Andreas Frick, Nicholas V. DiPatrizio, Ken Mackie, Istvan Katona, Daniele Piomelli and Olivier J. Manzoni | | | Fragile X syndrome is a major genetic cause of autism and is caused by loss of the fragile X mental retardation protein. In a mouse model of fragile X syndrome, Jung et al. show that an absence of neuronal endocannabinoid signalling is responsible for the neurophysiological and behavioural defects. | | | 25 Sep | Nat Commun 3:1080 doi:10.1038/ncomms2045 (2012) | | | Biological sciences Neuroscience | | Abstract | Full Text | PDF (1,277 kB) |

| Genetic architecture supports mosaic brain evolution and independent brain–body size regulation | | | Reinmar Hager, Lu Lu, Glenn D. Rosen and Robert W. Williams | | | It has been controversial whether the sizes of different regions of the brain can evolve independently of each other. This study identifies genetic loci responsible for independent size regulation in different brain regions, and finds brain size to be regulated independently of body size. | | | 25 Sep | Nat Commun 3:1079 doi:10.1038/ncomms2086 (2012) | | | Biological sciences Evolution | | | Genetics Neuroscience | | | Abstract | Full Text | PDF (507 kB) |

Hofmann, Michelle Nessling, Karsten Richter, Mario Schiffer, Lucie Carrier, L. Christian Napp, Johann Bauersachs, Kamal Chowdhury and Thomas Thum | | | Heart failure is often a consequence of pathological growth of cardiomyocytes or cardiac hypertrophy. Here Ucar and colleagues report that the microRNAs miR-132 and miR-212 promote cardiac hypertrophy and inhibit autophagy in cardiomyocytes by downregulating the transcription factor FoxO3. | | | 25 Sep | Nat Commun 3:1078 doi:10.1038/ncomms2090 (2012) | | | Biological sciences Cell biology | | | Medical research | | Abstract | Full Text | PDF (1,186 kB) |
