Drought imperils carbon sequestration in European forests

Forests play a critical part in mitigating climate change due to their ability to absorb CO2 from the atmosphere. However, many European forests removed less CO2 from the atmosphere during the extremely hot and dry summer ...

How microplastics end up in the marine atmosphere

Microplastic particles are present in the marine atmosphere even in remote parts of the world. These tiny particles come from land sources but are also re-emitted into the atmosphere from the sea, a study by a team of German ...

Exploring the role of ice sheets for the climate

In recent decades the ice sheets of Greenland and Antarctica have decreased dramatically, and scientific projections suggest an increasing retreat in the future. Ice sheets form on land in regions with sufficient snowfall, ...

Defying gravity with the Brazil nut effect

Physicists from the University of Utrecht and the Faculty of Physics at the University of Warsaw have observed—for the first time experimentally—the Brazil nut effect in a mixture of charged colloidal particles.

Simplified calculations reproduce complex plasma flows

Accurate and fast calculation of heat flow (heat transport) due to fluctuations and turbulence in plasmas is an important issue in elucidating the physical mechanisms of fusion reactors and in predicting and controlling their ...
