New insights on final Epigravettian funerary behavior at Arene Candide cave (Western Liguria, Italy)

We gained new insights on Epigravettian funerary behavior at the Arene Candide cave through the osteological and spatial analysis of the burials and human bone accumulations found in the cave during past excavations. Archaeothanathological information on the human skeletal remains was recovered from diaries, field pictures and notes, and data from recent excavations was integrated. The secondary deposits have traditionally been interpreted as older burials that were disturbed to make space for new inhumations. Our results suggest that those disturbances were not casual: older burials were intentionally displaced to bury younger inhumations. Subsequently, some skeletal elements, especially crania, were arranged around the new burial; these were often placed within stone niches. Based on the composition of some clusters, which contain the bones of two individuals displaced together, it is possible that a double burial composed of two adults was originally present at the site. This would be a burial type that had not been recognized at Arene Candide until now. Strikingly, this potential double burial contained an individual showing pathological bowing of the limbs, a finding which is not infrequent in skeletons from Gravettian and Epigravettian multiple burials. In addition, the crania and other skeletal elements derived from this burial were intentionally placed around a new inhumation, whose skeleton possibly shows a milder form of the same disease (possibly hereditary rickets). This and other observations suggest that the five individuals belonging to the second phase of this “cemetery” (AMS dates spanning 12,030 – 11,180 cal BP) might have been buried over a relatively brief time span. Our study demonstrated similar behaviors in the first phase of mortuary use of the cave (12,820 – 12,420 cal BP), indicating a remarkable persistence in Final Epigravettian funerary models despite their archaeologically apparent rarity and intermittent nature

Efficacy of foot orthoses for the treatment of plantar heel pain:a systematic review and meta-analysis

BackgroundPlantar heel pain (PHP) is common. Foot orthoses are often applied as treatment for PHP, even though there is little evidence to support this.ObjectiveTo investigate the effects of different orthoses on pain, function and self-reported recovery in patients with PHP and compare them with other conservative interventions.DesignSystematic review and meta-analysis.Data sourcesA systematic literature search was conducted in MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, Web of Science, CINAHL and Google Scholar up to January 2017.Eligibility criteria for selecting studiesRandomised controlled trials comparing foot orthoses with a control (defined as no intervention, sham or other type of conservative treatment) reporting on pain, function or self-reported recovery in patients with PHP.ResultsTwenty studies investigating eight different types of foot orthoses were included in the review. Most studies were of high quality. Pooled data from six studies showed no difference between prefabricated orthoses and sham orthoses for pain at short term (mean difference (MD) of 0.26 (95% CI −0.09 to 0.60)). No difference was found between sham orthoses and custom orthoses for pain at short term (MD 0.22 (95% CI −0.05 to 0.50)), nor was there a difference between prefabricated orthoses and custom orthoses for pain at short term (MD 0.03 (95% CI −0.15 to 0.22)). For the majority of other interventions, no significant differences were found.ConclusionsFoot orthoses are not superior for improving pain and function compared with sham or other conservative treatment in patients with PHP.PROSPERO registration numberCRD42015029659.</jats:sec

New Radar Interferometric Time Series Analysis Toolbox Released

Interferometric synthetic aperture radar (InSAR) has become an important geodetic tool for measuring deformation of Earth’s surface due to various geophysical phenomena, including slip on earthquake faults, subsurface migration of magma, slow‐moving landslides, movement of shallow crustal fluids (e.g., water and oil), and glacier flow. Airborne and spaceborne synthetic aperture radar (SAR) instruments transmit microwaves toward Earth’s surface and detect the returning reflected waves. The phase of the returned wave depends on the distance between the satellite and the surface, but it is also altered by atmospheric and other effects. InSAR provides measurements of surface deformation by combining amplitude and phase information from two SAR images of the same location taken at different times to create an interferogram. Several existing open‐source analysis tools [Rosen et al., 2004; Rosen et al., 2011; Kampes et al., 2003 ; Sandwell et al., 2011] enable scientists to exploit observations from radar satellites acquired at two different epochs to produce a surface displacement map

Boolean network model predicts cell cycle sequence of fission yeast

A Boolean network model of the cell-cycle regulatory network of fission yeast (Schizosaccharomyces Pombe) is constructed solely on the basis of the known biochemical interaction topology. Simulating the model in the computer, faithfully reproduces the known sequence of regulatory activity patterns along the cell cycle of the living cell. Contrary to existing differential equation models, no parameters enter the model except the structure of the regulatory circuitry. The dynamical properties of the model indicate that the biological dynamical sequence is robustly implemented in the regulatory network, with the biological stationary state G1 corresponding to the dominant attractor in state space, and with the biological regulatory sequence being a strongly attractive trajectory. Comparing the fission yeast cell-cycle model to a similar model of the corresponding network in S. cerevisiae, a remarkable difference in circuitry, as well as dynamics is observed. While the latter operates in a strongly damped mode, driven by external excitation, the S. pombe network represents an auto-excited system with external damping.Comment: 10 pages, 3 figure

Are Amphipod invaders a threat to the regional biodiversity? Conservation prospects for the Loire River

The impact of invasions on local biodiversity is well established, but their impact on regional biodiversity has so far been only sketchily documented. To address this question, we studied the impact at various observation scales (ranging from the microhabitat to the whole catchment) of successive arrivals of non-native amphipods on the amphipod assemblage of the Loire River basin in France. Amphipod assemblages were studied at 225 sites covering the whole Loire catchment. Non-native species were dominant at all sites in the main channel of the Loire River, but native species were still present at most of the sites. We found that the invaders have failed to colonize most of tributaries of the Loire River. At the regional scale, we found that since the invaders first arrived 25 years ago, the global amphipod diversity has increased by 33% (from 8 to 12 species) due to the arrival of non-native species. We discuss the possibility that the lack of any loss of biodiversity may be directly linked to the presence of refuges at the microhabitat scale in the Loire channel and in the tributaries, which invasive species have been unable to colonize. The restoration of river quality could increase the number of refuges for native species, thus reducing the impact of invader
