Biochemist pretending real hard that I’m a microbiologist, when I actually wish I was an entomologist. I research, teach, and serve at Cornhusker U. GBR!
Frank likes to roll around under the ottoman, and with the color and pattern of the rug, he’s pretty effectively camouflaged…

This is the line I highlight as my favorite in all of biomedical literature when I teach DNA structure in my spring Molecular Biology course. Lol…
Nature suggests you use their "Manuscript Adviser" bot to get advice before submitting
I uploaded the classic Watson & Crick paper about DNA structure, and the Adviser had this to say about one of the greatest paper endings of the century:

Lucy and her mantis friend at age 5, and hissing cockroach friends at age 13… I think she may have inherited the entomologist gene from me!

Sometimes I wonder how all the different coat colors and patterns in, say, Dachshunds came to be. Then I see posts like the one below and it’s like “oh, yeah, one popped up in a litter randomly and was selected.”

The person who lost control of their car and drove through my yard late Wednesday did manage to miss the 12-foot skeletons and for that, I am grateful 🙏

Reposting this to remind me to talk about it in class…Today was on nitrogen fixing bacteria that live in the fungus gardens of leaf cutter ants.
So I guess this could be part of the microbial physiology physiology course with a strong myrmecological theme…

Scientists revive old Bulgarian recipe to make yogurt with ants. Ants carry lactic and acetic acid bacteria that help coagulate milk, as well as formic acid to acidify it. They even partnered with Danish chefs to create three recipes using ant yogurt. arstechnica.com/science/2025...

“Twilight Override,” the latest solo project by Jeff Tweedy, who leads the long-running band Wilco, is a triple album that earns every minute. “I just thought that it flies in the face of a culture that’s gotten faster, more surface level,” he said. nyti.ms/4ngMQgu

Yet again, never having learned how to swim remains a net positive as far as I’m concerned.
Swimmer's itch is caused by microscopic parasites in the water.
Scientists are working to figure out whether certain waterfowl, invasive species or warming lakes could be factors driving the increase, and whether anything can be done to prevent it.

Scientists look for cause of spike in swimmer’s itch plaguing Minnesota lakes
The itchy red rash is caused by tiny parasites in the water that can burrow into human skin. Researchers are looking at whether certain waterfowl, invasive species or warming lakes could be factors.

Last of the hot peppers for the season! Scotch Bonnet, Habenero, Jalapeño, and Habenada (a mutant Habenero that has a defective capsaicin biosynthetic pathway.)
Turning some of these into jam shortly!

I’ve told students for years now, a good term paper idea for an evolution/pop gen course or a music course (or both!) would be a thorough analysis of the claims in Kendrick Lamar’s “DNA” through the lens of genes x environment interactions. There’s a lot to mine, there.

Caveat: this only works in rats that have been engineered to express a cocaine responsive ion channel in the brain. Probably not going to stop a given human from using or help someone get clean any time in the near future...but still very, very cool approach!
A new biochemical approach to combat addiction, developed by researchers at @UC San Diego and the National Institute on Drug Abuse (@NIDAnews), has shown promising results in reducing drug-seeking behavior. https://bit.ly/3V0MvlK #SpeakUp4Science
Rewiring Addiction With Designer Proteins
By custom engineering proteins in the brain, scientists at UC San Diego have shown that addiction can be rewired at the molecular level without negatively impacting enjoyment of normal activities.

It’s a shame I can’t go back in time like 25 or 30 years and ask the yeast genome sequencing and KO collection folks to use something other than S288c derivatives & designer deletion strains. The BY474x strains suck!

Yeah, still got it! (Doing yeast genetics with my own hands, that is.)
Measuring mutagenesis efficiency by EMS in 2 S. cerevisiae wild-types, by loss of CAN1 function leading to canavanine resistant colonies.
Does the BY474x background have a mismatch repair defect? 🤔

It’s Friday afternoon and I was working in the lab all day and my impulse control was slipping so I gave in. I finally did it. Almost felt like I didn’t have a choice…

Stay tuned on Monday to see what grows… 👅 🧪 🦠 🤓
