Visualization of embolism formation using cold neutron radiography
Formation and repair of xylem embolism are of great importance for plant water relations, but are not easy to monitor. Tötzke et al. examine intact and cut stems of the lianas Adenia lobata, Aristolochia macrophylla and Parthenocissus tricuspidata using cold neutron radiography, and use image processing to distinguish between low attenuation gas spaces and high-attentuation (water-containing) […] More

Evolution and speciation in Sorbus
Interspecific hybridization and polyploidy are key processes in plant evolution and are responsible for ongoing genetic diversification in the genus Sorbus (Rosaceae). Ludwig et al. study mating systems of diploid, triploid and tetraploid taxa in a diversity ‘hotspot’ for Sorbus in south-west England and find mating inter-relationships to be complex, and to provide the driving force […] More

In practice, these skills are easily noticeable in animals by […] More
