Faster than ever — neutron tomography detects water uptake by roots

New high-speed neutron tomography generates a complete 3D image every 1.5 seconds and is thus seven times faster than before. The method facilitates a better understanding of water and nutrient uptake of crop plants. The method can also be applied to investigate transport processes in various porous material systems.

Aerosols from coniferous forests no longer cool the climate as much

Emissions of greenhouse gases have a warming effect on the climate, whereas small airborne particles in the atmosphere, aerosols, act as a cooling mechanism. That is the received wisdom in any case. However, new research can now show that the tiniest aerosols are increasing at the expense of the normal sized and slightly larger aerosols — and it is only the latter that have a cooling effect.
