Although the notion of an early origin and diversification of life on Earth during the Archaean eon has received increasing support in geochemical, sedimentological and palaeontological evidence, ambiguities and controversies persist regarding the biogenicity and syngeneity of the record older than Late Archaean1–3. Nonbiological processes are known to produce morphologies similar to some microfossils4,5, and hydrothermal fluids have the potential to produce abiotic organic compounds with depleted carbon isotope values6, making it difficult to establish unambiguous traces of life. Here we report the discovery of a population of large (up to about 300 mmin diameter) carbonaceous spheroidal microstructures in Mesoarchaean shales and siltstones of the Moodies Group, South Africa, the Earth’s oldest siliciclastic alluvial to tidalestuarine deposits7. These microstructures are interpreted as organic-walled microfossils on the basis of petrographic and geochemical evidence for their endogenicity and syngeneity, their carbonaceous composition, cellular morphology and ultrastructure, occurrence in populations, taphonomic features of soft wall deformation, and the geological context plausible for life, as well as a lack of abiotic explanation falsifying a biological origin. These are the oldest and largest Archaean organic-walled spheroidal microfossils reported so far. Our observations suggest that relatively large microorganisms cohabited with earlier reported benthic microbial mats8 in the photic zone of marginal marine siliciclastic environments 3.2 billion years ago.

Enteropathogenic (EPEC) and enterohemorrhagic (EHEC) Escherichia coli infections are characterised by the formation of attaching and effacing (AE) lesions on intestinal epithelial cells. Secretion of extracellular proteins (EspA, EspB, and EspD) via a type III secretion apparatus is necessary for the formation of the AE lesions by human EPEC. In this study, we show that bovine EPEC and EHEC are also able to secrete polypeptides homologous to the already described Esp proteins, most probably via a type III secretion system. Bovine EPEC and EHEC strains present two different secretion profiles of Esp proteins which correlate to the pathotypes of the esp genes as determined by PCR. We also demonstrate that genes encoding secreted proteins, present in the LEE of two bovine strains, are organised in the same way as in the human EPEC strain E2348/69. [less ▲]

Diblock copolymers of polymethacrylic acid sodium salt, forming the hair, and styrene derivatives have been studied in aqueous solutions by SANS and by SAXS. The influence of both the chemical nature and the length of the hydrophobic block on the size and shape of micelles have been investigated. The micellar core size is in agreement with the theoretical evaluation for copolymers with a short hydrophobic sequence. In contrast, in case of larger hydrophobic blocks, the measured size is incompatible with a star-like model. Various hypotheses are presented for the latter. [less ▲]

Face à l’arrivée – dès le 1er septembre 2007 – de nombreux dossiers RCD, plusieurs modalités de réaction s’offraient aux Tribunaux du travail, dans un contexte marqué par le Nouveau Management Public. L’étude du cas liégeois révèle des modalités singulières d’adaptation collective, prenant la forme d’une 14e Chambre et tranchant nettement avec des réactions attendues et plus classiques de défection, loyauté ou prise de parole face à un sujet de mécontentement d’autant plus aisé à comprendre qu’il se situe dans un contexte politique plus large de rationalisation des moyens alloués. L’analyse de l’organisation interne de cette 14e Chambre permet de saisir la contingence caractéristique du RCD en Belgique, ses effets sur le travail des médiateurs et le potentiel d’adaptation des ressources humaines qui composent les rouages judiciaires.
