Morse, Michael David | ???X??+ band systems of jet-cooled ScCo and YCo | Rotationally resolved resonant two-photon ionization (R2PI) spectra of ScCo and YCo are reported. The measured spectra reveal that these molecules possess ground electronic states of 1?+ symmetry, as previously found in the isoelectronic Cr2 and CrMo molecules. The ground state rotational constant... | | 2010 |

Adler, Frederick R. | Alternating host cell tropism shapes the persistence, evolution and coexistence of Epstein-Barr virus infections in human | Epstein-Barr virus (EBV) infects and can persist in a majority of people worldwide. Within an infected host, EBV targets two major cell types, B cells and epithelial cells, and viruses emerging from one cell type preferentially infect the other. We use mathematical models to understand why EBV infec... | | 2010 |

Adler, Frederick R. | Effects of intraspecific density-dependence on species richness and species abundance distributions | Abstract Species richness and patterns of abundance result from the interplay between niche differences, realized as intraspecific density-dependence (IDD), and so-called neutral processes that arise when species fitnesses are similar. This paper presents an extension of neutral models that incorpo... | | 2010 |

Bohs, Lynn A. | Eggplant origins: out of Africa, into the Orient | The eggplant (Solanum melongena L.), also known as aubergine or brinjal, has been cultivated for centuries in the Old World and is currently a crop species of global importance. Despite this, hypotheses of eggplant evolution have been fraught with controversy. Previous conclusions have relied solely... | Eggplant origins; Crop domestication; Solanum melongena complex; Solanum incanum; DNA sequence; Africa; Asia | 2010 |

Armentrout, Peter B. | Guided ion beam and theoretical studies of the reaction of Ag+ with CS2: gas-phase thermochemistry of AgS+ and AgCS+ and insight into spin-forbidden reactions | The gas-phase reactivity of the atomic transition metal cation, Ag+, with CS2 is investigated using guided-ion beam mass spectrometry. Endothermic reactions forming AgS+ and AgCS+ are observed but are quite inefficient. This observation is largely attributed to the stability of the closed shell Ag+(... | | 2010 |

Capecchi, Mario R. | Hematopoietic origin of pathological grooming in Hoxb8 mutant mice | Mouse Hoxb8 mutants show unexpected behavior manifested by compulsive grooming and hair removal similar to humans with OCD-spectrum disorder trichotillomania. Since Hox gene disruption often has pleiotropic effects, the root cause of this behavioral deficit was unclear. Here we report that, in the b... | | 2010 |
