Die Arktis bei 2,7 Grad globaler Erwärmung: Schwindende Landschaften
Physik in unserer Zeit, EarlyView.Eine dicke Eisschicht auf dem Ozean, hunderte Meter tief gefrorener Boden und ein über 3 000 m hoher Eisschild – diese einzigartige Landschaft wird es vermutlich so in Zukunft nicht mehr geben. Eine globale Erwärmung von 2,7 °C, auf die wir aktuell zusteuern, würde die Arktis bis zur Unkenntlichkeit verändern.

Mikrometeorite und ihr Ursprung im Sonnensystem: Außerirdischer Staub zum Anfassen
Physik in unserer Zeit, EarlyView.Mit einer Größe, die der Dicke eines Haares entspricht, sind Mikrometeorite kaum sichtbar für das bloße Auge. Dennoch werden sie seit etwa 150 Jahren gesammelt, und seit wenigen Jahren sogar auf unseren Hausdächern. Als Kostproben von Asteroiden oder Kometen stellen sie wertvolle Boten unseres Sonnensystems dar.

The Cinderella tree, Quillaja saponaria – A soap story
PLANTS, PEOPLE, PLANET, EarlyView.Our current understanding of plants has been shaped by the entwining of different cultures. The Chilean soapbark tree, traditionally valued as a source of natural soap, was shown by serendipitous research in France in the 1900s to produce compounds that can boost the immune response to vaccines.

PLANTS, PEOPLE, PLANET, EarlyView.Plants, like humans, have a microbiome that helps them grow, defend themselves against pathogens, acquire nutrients, and protect themselves against environmental stresses. The microbiome of tomatoes, a staple crop grown worldwide, could be utilized not only to reduce fertilizer and pesticide applications, but also to clean up harmful pollutants ...

Deep Reinforcement Learning‐Based Control for Real‐Time Hybrid Simulation of Civil Structures
International Journal of Robust and Nonlinear Control, EarlyView.ABSTRACT Real‐time Hybrid Simulation (RTHS) is a cyber‐physical technique that studies the dynamic behavior of a system by combining physical and numerical components that are coupled through a boundary condition enforcer. In structural engineering, the numerical components are subjected to environmental loads that become dynamic displacements of the ...
