AbstractVertebrate cells display a specific Golgi apparatus architecture, known as the “ribbon”, where the functional subunits, the mini-stacks, are linked into a tridimensional network. The importance of the ribbon architecture is underscored by evidence of its disrupt...

Abstract. Polar mesosphere summer echoes (PMSE) are very strong radar echoes primarily studied in the VHF wavelength range from altitudes close to the polar summer mesopause. Radar waves are scattered at irregularities in the radar refractive index which at mesopause al...

SummaryThe higher-order metaphase chromosome organization has been under controversial discussion already for 140 years. Classical light and electron microscopy proposed chromatids to be composed of helically organized chromatin fibers, so-called chromonemata. More rece...

The study of the visual system and its role for human cognition in health and disease with fMRI often requires the use of localizer paradigms to define anatomical regions of interest (ROIs). However, the considerable degree of interindividual variability of the cerebral...

International audience; Installation of an Ocean Thermal Energy Conversion pilot plant (OTEC) off the Caribbean coast of Martinique is expected to use approximately 100 000 m 3 h-1 of deep seawater for its functioning. This study examined the potential effects of the co...

Large volcanic eruptions occurring in the last glacial period can be detected in terms of their deposited sulfuric acid in continuous ice cores. Here we employ continuous sulfate and sulfur records from three Greenland and three Antarctic ice cores to estimate the emiss...

Abstract. Combined in situ and laboratory studies were conducted to document the effects of anoxia on the structure and functioning of meiobenthic communities, with special focus on harpacticoid copepods. In a first step, anoxia was created artificially by means of an u...

Sociality is a fundamental organizing principle across taxa, thought to come with a suite of adaptive benefits. However, making causal inferences about these adaptive benefits requires experimental manipulation of the social environment, which is rarely feasible in the ...

Creating increasingly realistic groundwater models involves the inclusion of additional geological and geophysical data in the hydrostratigraphic modeling procedure. Using multiple-point statistics (MPS) for stochastic hydrostratigraphic modeling provides a degree of fl...

Fatty acid desaturase 2 (Fads2) is the key enzyme of long-chain polyunsaturated fatty acid (LC-PUFA) biosynthesis. Endogenous production of these biomolecules in vertebrates, if present, is insufficient to meet demand. Hence, LC-PUFA are considered as conditionally esse...
