History tells us that if you dig a hole, it will be filled in. A hole near Rennes became a dump. A hole near Niagara became a dump. Rennes is a treasure trove. Love Canal stands as a cautionary tale.

There were two studies showing microplastics in medical IVs when I wrote my May Design World column. There are now at least 5.
I explain my own efforts to understand microplastics in medical IVs only to be beaten to the punch by other researchers.

Technical thinking: PVCs, IVs, and questioning risk
By Mark Jones I got skunked. Two groups published an idea I had before I could complete the research. But let’s go back to the beginning. Ever the

I presented my results on concentration and removal of micro and nanoplastics at the @acs.org San Diego meeting. Lots of videos that are also posted. mjphd.net/Presentation...

It will sound like I’m stuck on black spatulas, but I wrote my Design World column that just published a while ago. It was my first use of spatulageddon and prompted the more detailed and now published R&D World article. Read what started it all at www.designworldonline.com/dont-trash-t...
Technical thinking: Don’t trash those plastic spatulas
By Mark Jones 2024 was the year of spatulageddon. Plastic spatulas were trashed due to reports of dangers lurking within. The journal article that raised

CBS This Morning ran a segment where all the hosts were waving around black plastic spoons with worried expressions. A nice piece in Bloomberg is less dire about brain plastic. www.bloomberg.com/opinion/arti... I talked with the author and some of our conversation made it into the article.
You Might Have Plastic in Your Brain. Don’t Panic — Yet.
It’s unsettling, but the amount is probably less than the plastic spoon’s worth grabbing the headlines.

Technical thinking: The perils of scale in software and ice cream
