Looks like 16+ briefs filed today in Monsanto v Durnell. Few actually addressing the question before the court. Glyphosate toxicology is not being adjudicated. Pretty crazy. www.supremecourt.gov/docket/docke...

"Forever chemicals" and pesticides are on produce. Can you wash them off?
Fresh fruits and vegetables can often come with toxic residues from pesticides, some of which contain so-called “forever chemicals.” Here’s how to limit your exposure

My messaging about acute toxicology being extrapolated to far more important endpoints (i.e., “safer than caffeine”) may have been lost, but it’s still a fun read.

NotebookLM graphics can take pages of text and references and turn them into a surprisingly good visual that captures the main points I’d try to make. A picture really can be worth a 1000 words & sometimes it makes clear that the confident takes on social media missed the point.

Durnell v Monsanto, Glyphosate
I've uploaded several rulings, briefs, and some of my additional writings, then asked for a “graphic summary,” and it wasn’t awful. I’ll expand on Substack in time, especially regarding monograph program limitations compared to regulatory consensus.
