Dead plants are probably bad for earthworms

I’ve gotten a number of questions recently about a new study titled “Glyphosate-based herbicides reduce the activity and reproduction of earthworms and lead to increased soil nutrient concentrations” that was recently published in the online journal Scientific Reports. Although the title seems pretty straightforward, there are some flaws in the study design that preclude any broad conclusions from this research. […]

Who funds my weed science program?

This is the second post in a series about transparency and funding sources for my weed science research program.

GLP, whose stated mission is to “explore the intersection of DNA research, media and policy to disentangle science from ideology”, commonly aggregates news stories. But when they re-posted this particular article, the headline was changed pretty […]
