Freezing rain is a typical weather disaster in winter and early spring over many regions of the world, even tropical areas. It develops as supercooled water (below 0 °C) in the air and freezes immediately after depositing ...

New study shows benefits of ammonium for pine root growth

In ecological terms, coniferous formations represent the biggest terrestrial carbon sink, they play an essential part in the pollination of the ecosystems where they grow and, moreover, help improve agricultural production. ...

Ammonium triggers formation of lateral roots

Despite the importance of changes in root architecture to exploit local nutrient patches, mechanisms integrating external nutrient signals into the root developmental program remain poorly understood. "Here, we show for the ...

Methane-eating bacteria like nitrogen, too

Methane-eating bacteria can degrade ammonium in addition to methane, as discovered by microbiologists at Radboud University and the Max Planck Institute in Bremen. Methane-eaters are important for the reduction of greenhouses ...
