While I've never seen the supreme court in action, I did have the unfortunate experience of serving on a provincial court jury last year. That experience didn't exactly give me faith in the robustness of our justice system, nor in the capabilities of our judges.

My 10 y/o officially has a mullet. And I'm afraid to say that it is glorious.

DNA from 3,600-year-old cheese sequenced by scientists | CNN Scientists have sequenced DNA from 3,600-year-old cheese, the oldest in the archaeological record. The intact cheese was found with mummified remains in China.

I'm torn, as being hurried with cheese still tops my list. It's a gouda way to go.

Pollen tends to clump in water, but mounting in glycerol usually works well. Over time glycerol can fade some of the pigments though. For permanent slides, pollen is usually washed in concentrated KOH and then mounted.

#Micorscopy community, does anyone know where I can order this type of bottle from? Or even what the proper name is for them?

GATA2 Induces a Stem Cell-Like Transcriptional Program in Macrophages That Promotes an Atherogenic Phenotype The upregulation of GATA2 in response to pro-atherosclerotic stimuli induces a stem cell-like phenotype in macrophages that promotes disease progression.

I'm excited to announce my labs newest paper in which we identify GATA2 as a driver of a stem cell-like phenotype of atherosclerotic plaque macrophages which promote the development of disease. #macrophages #atheroscerlosis

Some things never change. My son has joined his first πŸ’ team (along with 2 of his friends) and has gotten his first jock strap...so just like when I was a kid, the first thing the three of them did was see how hard they could kick eachother in the crotch.

This is a bit of a long shot, but does anyone know of a source for the OT-IIZ T cell hybridoma (immortalized OT-II T cells)? I've been unable to find a cell repository that carries it. #Immunosky

A stein of (very good) homebrewed German lager, in front of a wood-fired pizza oven. The stein says in German (poorly translated by me):

Those who drink beer sleep well,
Those who sleep well commit no sins,
Those who commit no sins go to heaven.

I've never seen ball lightning, but once while backpacking with my brother we were in our tent during a storm and had St. Elmo's fire running up and down the tentpoles (it hissed!). Later we learned that we should have immediately got the hell out of there, as it often preceeds a lightning strike.
