The origins and development of the arid and highly seasonal steppe-desert biome in Central Asia, the largest of its kind in the world, remain largely unconstrained by existing records. It is unclear how Cenozoic climatic, geological, and biological forces, acting at diverse spatial and temporal scales, shaped Central Asian ecosystems through time. Our synthesis shows that the Central Asian...

Methyl-branched lipids promote the membrane adsorption of α-synuclein by enhancing shallow lipid-packing defects

Garten, Matthias ; Prévost, Coline ; Cadart, Clotilde ; Gautier, Romain ; Bousset, Luc ; Melki, Ronald ; Bassereau, Patricia ; Vanni, Stefano

In: Physical Chemistry Chemical Physics, 2015, vol. 17, no. 24, p. 15589–15597

Alpha-synuclein (AS) is a synaptic protein that is directly involved in Parkinson's disease due to its tendency to form protein aggregates. Since AS aggregation can be dependent on the interactions between the protein and the cell plasma membrane, elucidating the membrane binding properties of AS is of crucial importance to establish the molecular basis of AS aggregation into toxic fibrils....

Unexpected presence of 14C in inorganic pigment for an absolute dating of paintings

Beck, Lucile ; Messager, Cyrielle ; Caffy, Ingrid ; Delqué-Količ, Emmanuelle ; Perron, Marion ; Dumoulin, Jean-Pascal ; Moreau, Christophe ; Degrigny, Christian ; Serneels, Vincent

In: Scientific Reports, 2020, vol. 10, no. 1, p. 9582

The absolute dating of paintings is crucial for tackling the problem of fake art. Investigations to authenticate paintings rely on an advanced knowledge of art history and a collection of scientific techniques. Radiocarbon dating is the only technique that gives access to an absolute time scale, but its application is limited to organic materials such as wood, canvas or natural binder....

Emerging climate signals in the Lena River catchment: a non-parametric statistical approach

Pohl, Eric ; Grenier, Christophe ; Vrac, Mathieu ; Kageyama, Masa

In: Hydrology and Earth System Sciences, 2020, vol. 24, no. 5, p. 2817–2839

Climate change has far-reaching implications in permafrost-underlain landscapes with respect to hydrology, ecosystems, and the population's traditional livelihoods. In the Lena River catchment, eastern Siberia, changing climatic conditions and the associated impacts are already observed or expected. However, as climate change progresses the question remains as to how far we are along this...

Probing intraband excitations in ${\mathrm{ZrTe}}_{5}$: A high-pressure infrared and transport study

Santos-Cottin, D. ; Padlewski, M. ; Martino, E. ; David, S. Ben ; Mardelé, F. Le ; Capitani, F. ; Borondics, F. ; Bachmann, M. D. ; Putzke, C. ; Moll, P. J. W. ; Zhong, R. D. ; Gu, G. D. ; Berger, H. ; Orlita, M. ; Homes, C. C. ; Rukelj, Z. ; Akrap, Ana

In: Physical Review B, 2020, vol. 101, no. 12, p. 125205

Zirconium pentatetelluride, ZrTe5, shows remarkable sensitivity to hydrostatic pressure. In this work we address the high-pressure transport and optical properties of this compound, on samples grown by flux and chemical vapor transport. The high-pressure resistivity is measured up to 2 GPa, and the infrared transmission up to 9 GPa. The dc conductivity anisotropy is determined using a...
