Ook planten hebben wel eens burenruzie
Herstel van de natuur op uitgeputte landbouwgrond en in natuurgebieden verloopt moeizaam. ‘Bodemtransplantatie’ kan mogelijk uitkomst bieden. Dat betoogt Martijn Bezemer, hoogleraar Ecologie van Plant-Microbe-Insect interacties. Oratie op 18 december.

Beter inzicht in concurrentiestrijd tussen microben in bodems en oceanen
Vooral neerslag en bodemzuurgraad bepalen welke microben in een bepaalde habitat overleven en welke niet. Deze kennis is van belang om de biodiversiteit in stand te houden. Leidse milieukundigen werkten mee aan het onderzoek. Publicatie in Nature op 1 augustus.

Engineering of antigen-saving dissolving microneedles for intradermal vaccine delivery
The intradermal administration route is attractive for vaccine delivery, because of the highly populated antigen-presenting cells in the skin. However, the skin’s main physical barrier, the stratum corneum, prevents vaccines from entering the skin.

Monitoring drought and salinity stress in agriculture by remote sensing for a sustainable future
Food security is challenged by a growing global population and by climate change. Drought and soil salinity are considered the most important ones that inhibit crop yield and distribution. Worryingly, climate change is predicted to increase not only their frequency and severity, but also their co-occurrence,…

Unsprayed field margins: effects on environment, biodiversity and agricultural practice
A management strategy has been developed for field margins to reduce pesticide drift to non-target areas and to promote biodiversity on arable land. To this end, 3 and 6 m wide strips along the edges of winter wheat, sugar beet and potato crops have been left unsprayed with herbicides and insecticides…
