First Precambrian palaeomagnetic data from the Mawson Craton (East Antarctica) and tectonic implications

A pilot palaeomagnetic study was conducted on the recently dated with in situ SHRIMP U-Pb method at 1134 ± 9 Ma (U-Pb, zircon and baddeleyite) Bunger Hills dykes of the Mawson Craton (East Antarctica). Of the six dykes sampled, three revealed meaningful results providing the first well-dated Mesoproterozoic palaeopole at 40.5°S, 150.1°E (A95 = 20°) for the Mawson Craton. Discordance between this new pole and two roughly coeval poles from Dronning Maud Land and Coats Land (East Antarctica) demonstrates that these two terranes were not rigidly connected to the Mawson Craton ca. 1134 Ma. Comparison between the new pole and that of the broadly coeval Lakeview dolerite from the North Australian Craton supports the putative ~40° late Neoproterozoic relative rotation between the North Australian Craton and the combined South and West Australian cratons. A mean ca. 1134 Ma pole for the Proto-Australia Craton is calculated by combining our new pole and that of the Lakeview dolerite after restoring the 40° intracontinental rotation. A comparison of this mean pole with the roughly coeval Abitibi dykes pole from Laurentia confirms that the SWEAT reconstruction of Australia and Laurentia was not viable for ca. 1134 Ma

Seismic and structural characterization of a pre-salt rifted section: the Lagoa Feia Group, Campos Basin, offshore Brazil

The exploration of pre-salt offshore SE Brazil presents a multifaceted deep-water scenario that is bringing new challenges to seismic interpretation in offshore Brazilian exploration and production. Reservoirs in this domain are complex, heterogeneous with layered carbonates which makes accurate reservoir characterization very challenging. Our study here deals with the seismic characterization of the stratigraphy of a lacustrine section from the Lagoa Feia Group (Winter et al., 2007) in the Campos Basin, which extends over an area of 100,000 km2. By using an extensive 2D seismic dataset and two deep well logs and core information, we propose a seismic facies analysis and structural characterization of the Lagoa Feia group focused in the inner proximal domain of the Campos basin. Inferences from well core and seismic stratigraphy clearly suggest that the all Lagoa Feia group has a syn-rift depositional character. Different pre- syn- and post-rift seismic stratigraphic units, with corresponding bounding surfaces, are then defined. Based on their seismic character, four seismic facies representing the main lithological package in the rift section are recognized: border fault deposits; fine grain-dominated re-sedimented deposits; coarse grain-dominated carbonate rich re-sedimented deposits; and an intrusive wipe-out zone affecting all the pre-salt unit. Using some simplified kinematic restoration we show that some of the normal faults affecting the lower units of the Lagoa Feia could be interpreted as pre-rift structures sensu latu but also as pre-existing structures re-activated during the main passive margin rift activities. By proposing this seismic classification and interpretation across the pre salt Campos Basin units, this work represents an introductory step to a facies classification and structural interpretation applicable at regional level in the internal SE Brazil offshore area

Rationalizing the development of live attenuated virus vaccines

Since the first demonstration of the protective effects of vaccinia inoculation, vaccination has been one of the medicine’s greatest successes. The design of vaccines against viral disease has evolved considerably over the last 50 years. Classically attenuated viruses, those created by passaging a virus in cultured cells, have proven to be an effective means for preventing many viral diseases, including smallpox, polio, measles, mumps, and yellow fever. However, empiric attenuation is not a reliable approach for all viruses and there are a number of safety issues associated with the use of live, attenuated viruses (LAVs). While inactivated viruses and subunit vaccines alleviate many of these concerns, they have generally been less efficacious than their LAV counterparts. Advances in molecular virology have provided new ways of controlling viral replication and virulence, renewing interest in LAV vaccines. These rationally attenuated viruses may lead to a new generation of safer, more widely applicable LAV vaccines. Here, we review several new approaches to viral attenuation and vaccine design, including deleterious gene mutation, altered replication fidelity, codon deoptimization, and control by microRNAs or zinc finger nucleases. While each of these approaches has garnered significant attention in recent months, they are still in their infancy and require further in vitro and animal testing before progressing to clinical trials
