A general theory of rock glacier creep based on in-situ and remote sensing observations

Cicoira, Alessandro ; Marcer, Marco ; Gärtner‐Roer, Isabelle ; Bodin, Xavier ; Arenson, Lukas U. ; Vieli, Andreas

In: Permafrost and Periglacial Processes, 2020, vol. 32, no. 1, p. 139-153

The ongoing acceleration in rock glacier velocities concurrent with increasing air temperatures, and the widespread onset of rock glacier destabilization have reinforced the interest in rock glacier dynamics and in its coupling to the climate system. Despite the increasing number of studies investigating this phenomenon, our knowledge of both the fundamental mechanisms controlling rock...

Cenozoic evolution of the steppe-desert biome in Central Asia

Barbolini, N. ; Woutersen, A. ; Dupont-Nivet, G. ; Silvestro, Daniele ; Tardif, D. ; Coster, P. M.

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....

From zero to six double bonds: phospholipid unsaturation and organelle function

Antonny, Bruno ; Vanni, Stefano ; Shindou, Hideo ; Thierry, Ferreira

In: Trends in Cell Biology, 2015, vol. 25, no. 7, p. 427–436

Cellular phospholipids (PLs) differ by the nature of their polar heads as well as by the length and unsaturation level of their fatty acyl chains. We discuss how the ratio between saturated, monounsaturated, and polyunsaturated PLs impacts on the functions of such organelles as the endoplasmic reticulum, synaptic vesicles, and photoreceptor discs. Recent experiments and simulations suggest...
