Arçonnay – Plaine d’Alençon

La fouille du site d’Arçonnay fait suite à des travaux de diagnostic archéologique réalisés par V. Gallien et B. Aubry (Afan/Inrap), sur le futur parc d’activités Saint-Gilles. Le chantier est localisé au sud de la ville d’Alençon (61), en limite nord du département de la Sarthe (72). La fouille se trouve plus exactement dans une zone initialement occupée par des champs voués aux cultures (openfield caractéristique de la Plaine d’Alençon). Le chantier se situe au environ des 140 m d’altitude,..

Port-en-Bessin-Huppain – Le Mont Castel

Depuis trois ans, le site du Mont Castel fait l’objet de fouilles archéologiques programmées à la fin de l’été. Cette année, c’est principalement l’occupation de la fin de l’indépendance gauloise qui a fait l’objet d’un travail de fond. Il est désormais possible de dresser dans ces grandes lignes les modalités d’occupation du site. Nous rappellerons toutefois, avant de présenter l’occupation de La Tène D2b, que le site est fortifié et occupé dès le Bronze final IIIa et fait l’objet durant le ..

SPHERE extreme AO system On-sky operation, final performance and future improvements

The SPHERE (Spectro-Polarimetric High-contrast Exoplanet Research) instrument aims at detecting extremely faint1sources (giant extrasolar planets) in the vicinity of bright stars . Such a challenging goal requires the use of a very-high-order performance Adaptive Optics [AO] system feeding the scientific instruments with a quasi-perfect flat wave front corrected from all the atmospheric turbulence and internal defects. This AO system, called SAXO (Sphere Ao for eXoplanet Observation) is the heart of the instrument, a heart beating 1200 time per second and providing unprecedented image quality for a large ground based telescope at optical/near infrared wavelength. We will present the latest results obtained on-sky, demonstrating its exceptional performance (in terms of correction quality, stability and robustness) and tremendous potentiality for exoplanet discovery

Photography-based taxonomy is inadequate, unnecessary, and potentially harmful for biological sciences

The question whether taxonomic descriptions naming new animal species without type specimen(s) deposited in collections should be accepted for publication by scientific journals and allowed by the Code has already been discussed in Zootaxa (Dubois & Nemésio 2007; Donegan 2008, 2009; Nemésio 2009a–b; Dubois 2009; Gentile & Snell 2009; Minelli 2009; Cianferoni & Bartolozzi 2016; Amorim et al. 2016). This question was again raised in a letter supported by 35 signatories published in the journal Nature (Pape et al. 2016) on 15 September 2016. On 25 September 2016, the following rebuttal (strictly limited to 300 words as per the editorial rules of Nature) was submitted to Nature, which on 18 October 2016 refused to publish it. As we think this problem is a very important one for zoological taxonomy, this text is published here exactly as submitted to Nature, followed by the list of the 493 taxonomists and collection-based researchers who signed it in the short time span from 20 September to 6 October 2016

Infevers: An evolving mutation database for auto-inflammatory syndromes

The Infevers database (http://fmf.igh.cnrs-fr/infevers/) was established in 2002 to provide investigators with access to a central source of information about all sequence variants associated with periodic fevers: Familial Mediterranean fever (IMF), TNF Receptor Associated Periodic Syndrome (TRAPS), Hyper IgD Syndrome (HIDS), Familial Cold Autoinflammatory Syndrome/Muckle-Wells Syndrome/Chronic Infantile Neurological Cutaneous and Articular Syndrome (FCAS/MWS/CINCA). The prototype of this group of disorders is IMF, a recessive disease characterized by recurrent bouts of unexplained inflammation. FMF is the pivotal member of an expanding family of autoinflammatory disorders, a new term coined to describe illnesses resulting from a defect of the innate immune response. Therefore, we decided to extend the Infevers database to genes connected with autoinflammatory diseases. We present here the biological content of the Infevers database, including the introduction of two new entries: Crohn/Blau and Pyogenic sterile arthritis, pyoderma gangrenosum and acne (PAPA syndrome). Infevers has a range of query capabilities, allowing for simple or complex interrogation of the database. Currently, the database contains 291 sequence variants in related genes (MEFV, TNFRSF1A, MVK, CARD15, PSTPIP1, and CIAS1), consisting of published data and personal communications, which has revealed or refined the preferential mutational sites for each gene. This database will continue to evolve in its content and to improve in its presentation. (C) 2004 Wiley-Liss, In
