With increasing species richness, due to more plant introductions than extinctions, plant communities of many European regions are becoming more homogeneous. The same species are occurring more frequently, whereas rare species are becoming extinct. It is not only the biological communities that are becoming increasingly similar, but also the phylogenetic relations between regions. These processes [...]

Many alcoholic beverages contain byproducts of the materials used in the fermenting process. These byproducts are called “congeners,” complex organic molecules with toxic effects including acetone, acetaldehyde, fusel oil, tannins, and furfural. Bourbon has 37 times the amount of congeners that vodka has. A new study has found that while drinking a lot of bourbon [...]
