Grades are submitted! It's such a relief to see ZERO Canvas app notifications. Best of all, for the first time in 4 years, I have no new course preps next semester. I can actually enjoy winter break! Applied Time Series Analysis was my new prep last semester, and it was brutal, but I'm proud of it!

NSF makes you say who you got conflicts (coauthored) with. We (really just Jordan Matelsky) just built you a tool for that. Literally one click: bib.experiments.kordinglab.com/nsf-coa

I thought I would make a starter pack of scientists working on #phytoliths. Please share if this is of interest to you, and do ask if you want to be added!

I just switched my professional/ research social presence from the dumpster fire formerly known as Twitter. Here’s a little blue sky from my back yard this past summer.

Is #ModernReferenceMonday a thing? #Kava (Piper methysticum var. kalihi) tabular facetate leaf #phytoliths. This plant was grown, collected, and sent to me from Hawaiʻi for an archaeological/ancient agriculture project I worked on several years ago.

I’m growing Oaxacan green dent corn in a plot at the ISU community garden this summer for #phytolith, and #starchgranule reference material. We will be looking at phytolith and starch degradation after grinding, #nixtamalization, and cooking steps. @EESatISU @indianastate

#FossilFriday ~300 Ma black shale with a fossilized #bryozoan (cf. Rhombopora sp.) and a few lithified coal clasts. Found in a creek bed when hiking with the family a few weeks ago here in Vigo Co, IN - USA. Cleaned this up with bleach, H2O rinse, and then 10% HCl. #carboniferous

I was making some #phytolith microscope slides at home and ran out of the fingernail polish that I use to seal coverslips. My wife said “I have some, but it’s like 20 years old.” It was my preferred brand for slide making! #Wet_n_Wild

Here's another page I made for a micro/macro #archaeobotany calendar from 2013 (see 1/11/21 post). I'm teaching a course on #microfossils in the Earth and archaeological sciences this semester @EESatISU, so I thought I'd recycle this artwork for the sponge lecture. #silicasponges
