POSTER - MITOCHONDRIAL FUNCTION AND CANCER
Author: Douglas C. Wallace
This Poster highlights some recent discoveries that have led to a renewed interest in the function of mitochondria in cancer cells. Mitochondria carry out a number of crucial functions in cells and these can be altered through mutations in either the nuclear DNA or the mitochondrial DNA.

This study presents a trans-dimensional hierarchical Bayesian framework that eliminates noise without loss of temporal resolution. | | | 04 Sep | Nat Commun 3:1048 doi:10.1038/ncomms2051 (2012) | | | Earth sciences Geology and geophysics | | Abstract | Full Text | PDF (515 kB) |

| The use of the sex pheromone as an evolutionary solution to food source selection in caterpillars | | | Erwan Poivet, Kacem Rharrabe, Christelle Monsempes, Nicolas Glaser, Didier Rochat, Michel Renou, Frédéric Marion-Poll and Emmanuelle Jacquin-Joly | | | Sex pheromones are used by adult members of a species to attract a mate. This study proposes that the larvae of the cotton leafworm Spodoptera littoralis are attracted to sex pheromones and prefer a food source containing it, suggesting an alternative use of the sex pheromone to trigger food search in caterpillars. | | | 04 Sep | Nat Commun 3:1047 doi:10.1038/ncomms2050 (2012) | | | Biological sciences Ecology | | | | | Abstract | Full Text | PDF (581 kB) |

| Evidence for methane production by saprotrophic fungi | | | Katharina Lenhart, Michael Bunge, Stefan Ratering, Thomas R. Neu, Ina Schüttmann, Markus Greule, Claudia Kammann, Sylvia Schnell, Christoph Müller, Holger Zorn and Frank Keppler | | | Methane is an important anthropogenic greenhouse gas and is thought to be produced by industrial processes and prokaryotic methanogenic Archaea. In this study, the saprotrophic fungi, Basidiomycetes, is shown to produce methane in the absence of methanogenic Archaea. | | | 04 Sep | Nat Commun 3:1046 doi:10.1038/ncomms2049 (2012) | | | Biological sciences Ecology | | | Microbiology | | Abstract | Full Text | PDF (949 kB) |

| Efficacy of the β2-adrenergic receptor is determined by conformational equilibrium in the transmembrane region OPEN | | | Yutaka Kofuku, Takumi Ueda, Junya Okude, Yutaro Shiraishi, Keita Kondo, Masahiro Maeda, Hideki Tsujishita and Ichio Shimada | | | Many drugs exist that target the β-adrenergic receptor, but they have different efficacies. Kofuku et al. use NMR to show that methionine 82 in the transmembrane domain undergoes conformational changes depending on whether agonists or inverse agonists are bound, explaining the differential drug efficacy. | | | 04 Sep | Nat Commun 3:1045 doi:10.1038/ncomms2046 (2012) | | | Biological sciences Biochemistry | | | Biophysics | | Abstract | Full Text | PDF (793 kB) |

Here, Bock et al. use probes to monitor the conformation of the M2 muscarinic receptor and show that the vestibule alters the extent of receptor movement. | | | 04 Sep | Nat Commun 3:1044 doi:10.1038/ncomms2028 (2012) | | | Biological sciences Biophysics | | | Chemical biology | | Abstract | Full Text | PDF (798 kB) |

| Spin-enhanced organic bulk heterojunction photovoltaic solar cells | | | Ye Zhang, Tek P. Basel, Bhoj R. Gautam, Xiaomei Yang, Debra J. Mascaro, Feng Liu and Z. Valy Vardeny | | | One of the obstacles to improving the efficiency of organic photovoltaic solar cells is the recombination of polaron pairs at the interface between donor and acceptor molecules. By doping cells with galvinoxyl radicals, Zhang et al. demonstrate a mechanism that overcomes this problem via a spin-flip process. | | | 04 Sep | Nat Commun 3:1043 doi:10.1038/ncomms2057 (2012) | | | Physical sciences Applied physics | | | Materials science | | Abstract | Full Text | PDF (750 kB) |

| Discovery of acetylene hydratase activity of the iron–sulphur protein IspH | | | Ingrid Span, Ke Wang, Weixue Wang, Yonghui Zhang, Adelbert Bacher, Wolfgang Eisenreich, Kai Li, Charles Schulz, Eric Oldfield and Michael Groll | | | The iron–sulphur enzyme IspH catalyses the final step of the methylerythritol phosphate isoprenoid biosynthesis pathway. Span et al. report that IspH can hydrate acetylenes to aldehydes and ketones, in addition to its role as a 2H+/2e- reductase. | | | 04 Sep | Nat Commun 3:1042 doi:10.1038/ncomms2052 (2012) | | | Biological sciences Biochemistry | | | Chemical biology | | Abstract | Full Text | PDF (1,664 kB) |

| The amniote paratympanic organ develops from a previously undiscovered sensory placode | | | Paul O'Neill, Siu-Shan Mak, Bernd Fritzsch, Raj K. Ladher and Clare V.H. Baker | | | The paratympanic organ in the avian middle ear is similar to the fish spiracular organ, but its developmental origin is unresolved. O'Neill et al. use fate mapping to show that the avian paratympanic organ and its afferent neurons arise from a placode that is distinct from the origin of the fish spiracular organ. | | | 04 Sep | Nat Commun 3:1041 doi:10.1038/ncomms2036 (2012) | | | Biological sciences Developmental biology | | | Evolution Neuroscience | | | | | Abstract | Full Text | PDF (1,811 kB) |

Ritchie, R. Torre, M. S. Vitiello and P. De Natale | | | Frequency comb synthesizers are important for metrology, but they have been difficult to use as frequency rulers in the terahertz region due to their low power. Consolino et al. phase-lock a quantum cascade laser to a free-space-propagating terahertz comb, demonstrating that they can overcome this limitation. | | | 04 Sep | Nat Commun 3:1040 doi:10.1038/ncomms2048 (2012) | | | Physical sciences Applied physics | | | Optical physics | | | Abstract | Full Text | PDF (437 kB) |
| Naphthol radical couplings determine structural features and enantiomeric excess of dalesconols in Daldinia eschscholzii | | | Wei Fang, Shen Ji, Nan Jiang, Wei Wang, Guo Yan Zhao, Su Zhang, Hui Ming Ge, Qiang Xu, Ai Hua Zhang, Ying Lao Zhang, Yong Chun Song, Jie Zhang and Ren Xiang Tan | | | The dalesconol natural products are biosynthesised in an enantiomeric excess of 67%, rather than as a single enantiomer or a racemate. Tan et al. report that this unusual enantioselectivity is a result of the dominance of particular conformers of naphthol dimer intermediates. | | | 04 Sep | Nat Commun 3:1039 doi:10.1038/ncomms2031 (2012) | | | Chemical sciences Biochemistry | | | Chemical biology | | | | | Abstract | Full Text | PDF (1,001 kB) |

Mælandsmo, Wolfgang Egge-Jacobsen and Pål Ø. Falnes | | | Methyltransferases modify cellular proteins in addition to DNA and histones. These authors identify a new family of lysine-specific methyltransferases and show that a member of this family, which is associated with tumour metastasis, methylates the ATP-dependent protein chaperone VCP/p97. | | | 04 Sep | Nat Commun 3:1038 doi:10.1038/ncomms2041 (2012) | | | Biological sciences Biochemistry | | | Cancer | | Abstract | Full Text | PDF (1,458 kB) |

Oppeneer | | | Spin dynamics in magnetic materials can be driven by ultrafast light pulses, resulting in transient magnetization changes on femtosecond timescales. Rudolph et al. find that in magnetic trilayers the magnetization of one layer can be enhanced by superdiffusive spin currents from adjacent layers. | | | 04 Sep | Nat Commun 3:1037 doi:10.1038/ncomms2029 (2012) | | | Physical sciences Condensed matter | | | Optical physics | | | | | Abstract | Full Text | PDF (717 kB) |

| Blind topological measurement-based quantum computation | | | Tomoyuki Morimae and Keisuke Fujii | | | Blind quantum computation is a protocol that permits an algorithm, its input and output to be kept secret from the owner of the computational resource doing the calculation. Morimae and Fujii propose a strategy for topologically protected fault-tolerant blind quantum computation that is robust to environmental noise. | | | 04 Sep | Nat Commun 3:1036 doi:10.1038/ncomms2043 (2012) | | | Physical sciences Theoretical physics | | | Abstract | Full Text | PDF (645 kB) |

This study demonstrates that introducing rhodium into nanoparticles consisting of the ε phase of Fe2O3 gives rise to a very high coercivity. | | | 04 Sep | Nat Commun 3:1035 doi:10.1038/ncomms2038 (2012) | | | Physical sciences Materials science Nanotechnology | | Abstract | Full Text | PDF (520 kB) |
