Particulate matter increases drought vulnerability of trees     2018/07/16 15:35

Particulate matter deposits on leaves increase plant transpiration and the risk of plants suffering from drought. Particulate matter could thus be contributing more strongly to tree mortality and forest decline than previously assumed. This is suggested by results from a greenhouse study, in which tree seedlings grown in almost particulate matter free air or in unfiltered air were compared.

Natural product that could lead to new class of commercial herbicide     2018/07/14 03:01

A team of engineers and scientists discovered a new and potentially highly effective type of weed killer. This finding could lead to the first new class of commercial herbicides in more than 30 years, an important outcome as weeds continue to develop resistance to current herbicide regimens.
