Nématode: ce ver microscopique ravageur menace les forêts de pins de cette région de France
Le nématode, un ver microscopique, a été détecté pour la première fois en France à Seignosse dans les Landes. Un ver ravageur venu d'Amérique du Nord et qui est très dangereux pour les pins.

I'm frequently asked if we can use XRM imaging to study Arabidopsis, and the answer is absolutely yes. The pollen grains were segmented using basic grayscale thresholding. This scan used the 4X lens, stayed tuned for results from the 20X.
