Sulfurospirillum diekertiae sp. nov., a tetrachloroethene-respiring bacterium isolated from contaminated soil

Christof Holliger, Julien Maillard, Junxiong Wang

Two anaerobic, tetrachloroethene- (PCE-) respiring bacterial isolates, designated strain ACSDCE T and strain ACSTCE, were characterized using a polyphasic approach. Cells were Gram-stain-negative, motile, non-spore-forming and shared a vibrioid- to spirill ...

A new Hypselogenia Burmeister, 1840 from Angola (Coleoptera, Scarabaeidae, Cetoniinae, Goliathini)

Michele De Palma

Morphological and DNA barcoding analysis identify a new species in the Afrotropical genus Hypselogenia Burmeister, 1840. Hypselogenia hassoni sp. nov. is described from the Cuanza Sul Province of Angola. The new species belongs to the Hypselogenia geotrupi ...

Mitochondrial Pseudogenes Suggest Repeated Inter-Species Hybridization among Direct Human Ancestors

Konstantin Popadin

The hypothesis that the evolution of humans involves hybridization between diverged species has been actively debated in recent years. We present the following novel evidence in support of this hypothesis: the analysis of nuclear pseudogenes of mtDNA ("NUM ...

The virtuous cycle of human genetics and mouse models in drug discovery

Johan Auwerx

Ongoing studies in many species seek to understand the origins, architecture and consequences of phenotypic variation under normal and dysfunctional conditions, with the aim of identifying targets for intervention that can prevent, stabilize or reverse dis ...

Imidacloprid induces adverse effects on fish early life stages that are more severe in Japanese medaka (Oryzias latipes) than in zebrafish (Danio rerio)

Kristin Schirmer, Juliane Hollender

Neonicotinoids are widely used insecticides that have frequently been found in freshwater with concentrations ranging from ng to mu g/L. It is known that these compounds impact non-target invertebrates, such as bees and gammaridae, in terms of toxicity and ...

Male-killing toxin in a bacterial symbiont of Drosophila

Bruno Lemaitre, Toshiyuki Harumoto

Several lineages of symbiotic bacteria in insects selfishly manipulate host reproduction to spread in a population 1 , often by distorting host sex ratios. Spiroplasma poulsonii2,3 is a helical and motile, Gram-positive symbiotic bacterium that resides in ...

Highly Reduced Genome of the New Species Mycobacterium uberis, the Causative Agent of Nodular Thelitis and Tuberculoid Scrotitis in Livestock and a Close Relative of the Leprosy Bacilli

Stewart Cole, Andrej Benjak, Charlotte Avanzi

Nodular thelitis is a chronic enzootic infection affecting dairy cows and goats. The causative agent was recently shown to be related to the leprosy-causing bacilli Mycobacterium leprae and Mycobacterium lepromatosis. In this study, the genome of this path ...

The Impact of Linked Selection in Chimpanzees: A Comparative Study

Jeffrey David Jensen, Susanne Petra Pfeifer

Levels of nucleotide diversity vary greatly across the genomes of most species owing to multiple factors. These include variation in the underlying mutation rates, as well as the effects of both direct and linked selection. Fundamental to interpreting the ...

The evolution of gene expression and binding specificity of the largest transcription factor family in primates

Didier Trono, Jeffrey David Jensen, Adamantia Kapopoulou, Lisha Mathew

The KRAB-containing zinc finger (KRAB-ZF) proteins represent the largest family of transcription factors (TFs) in humans, yet for the great majority, their function and specific genomic target remain unknown. However, it has been shown that a large fractio ...

One-Pot Polyol Synthesis of Pt/CeO2 and Au/CeO2 Nanopowders as Catalysts for CO Oxidation

Christian Ludwig, Andrea Testino, Mohamed Tarik, Frank Pilger

The facile one-pot synthesis of CeO2-based catalysts has been developed to prepare a relatively large amount of nanopowders with relevant catalytic activity towards CO oxidation. The method consists of a two-steps process carried out in ethylene glycol: in ...
