8 p, 950.6 KB Earliest modern human-like hand bone from a new 41.84-million-year-old site at Olduvai in Tanzania / Domínguez-Rodrigo, Manuel (Universidad Complutense de Madrid. Departamento de Prehistoria) ; Rayne Pickering, Travis (University of Wisconsin-Madison. Department of Anthropology) ; Almécija, Sergio (Institut Català de Paleontologia Miquel Crusafont) ; Heaton, Jason L.

Archaeology Unit) ; Uribelarrea, David (Universidad Complutense de Madrid. Departamento de Geodinámica)
Modern humans are characterized by specialized hand morphology that is associated with advanced manipulative skills. Thus, there is important debate in paleoanthropology about the possible cause–effect relationship of this modern human-like (MHL) hand anatomy, its associated grips and the invention and use of stone tools by early hominins.

Apart from being so far the only known binary multiferroic compound, CuO has a much higher transition temperature into the multiferroic state, 230 K, than any other known material in which the electric polarization is induced by spontaneous magnetic order, typically lower than 100 K. [...]

8 p, 752.8 KB Environmental variation and the evolution of large brains in birds / Sayol i Altarriba, Ferran (Centre de Recerca Ecològica i Aplicacions Forestals)) ; Maspons, Joan (Centre de Recerca Ecològica i Aplicacions Forestals) ; Lapiedra i González, Oriol (Harvard University.

Department of Biology and Biochemistry) ; Sol, Daniel (Centre de Recerca Ecològica i Aplicacions Forestals)
Environmental variability has long been postulated as a major selective force in the evolution of large brains. However, assembling evidence for this hypothesis has proved difficult. Here, by combining brain size information for over 1,200 bird species with remote-sensing analyses a to estimate temporal variation in ecosystem productivity, we show that larger brains (relative to body size) are more likely to occur in species exposed to larger environmental variation throughout their geographic range.

Institut de Ciències Fotòniques) ; Winter, Andreas (Universitat Autònoma de Barcelona. Departament de Física)
The laws of thermodynamics, despite their wide range of applicability, are known to break down when systems are correlated with their environments. Here we generalize thermodynamics to physical scenarios which allow presence of correlations, including those where strong correlations are present. [...]

Global gridded crop models (GGCMs) are increasingly used for agro-environmental assessments and estimates of climate change impacts on food production. Recently, the influence of climate data and weather variability on GGCM outcomes has come under detailed scrutiny, unlike the influence of soil data. [...]

(Bethune-Cookman University. Department of Natural Sciences) ; Vences, Miguel (Technische Universität Braunschweig. Division of Evolutionary Biology)
Anuran amphibians undergo major morphological transitions during development, but the contribution of their markedly different life-history phases to macroevolution has rarely been analysed. Here we generate testable predictions for coupling versus uncoupling of phenotypic evolution of tadpole and adult life-history phases, and for the underlying expression of genes related to morphological feature formation.
