3-D structures of planetary nebulae
Journal of Physics: Conference Series, 2016 Recent advances in the 3-D reconstruction of planetary nebulae are reviewed. We include not only results for 3-D reconstructions, but also the current techniques in terms of general methods and software. In order to obtain more accurate reconstructions, we suggest to extend the widely used assumption of homologous nebula expansion to map ...

Climate Change Threatens Micronutrient Density of European Winter Wheat
Advanced Science, EarlyView.Micronutrients are vital for human health. Wheat is a major staple crop and a significant source of minerals and B‐vitamins. The impact of climate change on their content remains largely unknown. We evaluated micronutrient levels in European winter wheat grown under historical and projected climate conditions. Our findings indicate that future climates

Alternating High‐Fat and Polysaccharide Diets Modulates Gut Phage‐Bacterial Interplay
Advanced Science, EarlyView.This study reveals how alternating high‐fat and polysaccharide diets reshape the human gut virome and enhance phage‐bacteria interactions. Using large‐scale metagenomic meta‐analysis and a time‐resolved mouse model, the authors show that diets strongly modulate phage abundance, lifestyle, and gene exchange, offering new insights into nutrition‐guided ...

STRUCTURE AND DYNAMICS OF PLANETARY MAGNETOSPHERES
, 2022 The interactions between the ambient plasmas and the objects of the Solar System result in variable exchanges both in time and space of mass, momentum and energy within different types of magnetospheres. The characterization of the sources, the general circulation and the losses of the magnetospheric plasmas as well as the identification of the ...
