In an immunocompromised older adult, is there a way to distinguish between sepsis and a flareup of the autoimmune condition? (anca-associated vasculitis)? All regularly tested sources of infection were ruled out.

Border Patrol agent's texts after he shot a Chicago woman five times will be released, judge rules The text messages a Border Patrol agent sent to colleagues and family after he shot a Chicago woman five times can be released to the public, a federal judge ruled.

"I fired five rounds, and she had seven holes. Put that in your book, boys.โ€

Thatโ€™s Border Patrol agent Charles Exum, texting after shooting U.S. citizen Marimar Martinezโ€”no body cam. He later said he was โ€œproudโ€ of his shooting skills. A federal judge just okayed releasing the texts, 1/2

The Board of Governors decided, unilaterally, that no published textbook in the field of sociology could be used in compliance with the law for an Intro to Sociology class. None.
Victor: There's not a single existing textbook on the market that could be used that would qualify under state law?
Zachary: Correct.
Victor: I'm sorry, that's kind of funny. Like, the absurdity of not a single sociology textbook getting past the censors. I mean, it makes me kind of proud of our colleagues, but...

I do want to shout-out my fellow sociologists, who have collectively created a discipline so woke that not a single one of our introductory textbooks can make it past Florida's censors.

Great work everyone.

Thatโ€™s why Faculty Mentoring Networks matter so much to me. As one FMN participant put it:

โ€œ[The] FMN is more than a network, it is a living ecosystem of people who believe education can change the world.โ€

One of the things I keep learning in my work is that meaningful curricular change doesnโ€™t happen in isolation. It happens when faculty have time, trust, and community to learn together.

This role connects directly with my leadership at BioQUEST and with my own genomics teaching.

Iโ€™m grateful for the invitation and energized to collaborate with GEP colleagues during this next phase of growth.

Excited to share some good news: I was invited to join the Board of Directors for the newly established @genomicsed.bsky.social nonprofit. GEP has grown into a national community with real momentum โ€” supporting faculty, expanding access to genomics + bioinformatics, and building equitable CUREs.

A slide titled โ€œWhat happened to Flint,โ€ with several photos illustrating the water crisis. Images include: a โ€œBeforeโ€ photo of downtown Flint; a cross-section of a lead pipe with corrosion control; a technician adjusting treatment controls in April 2014; the Flint River; the Flint Water Plant tower; two water samples labeled Flint and Detroit showing stark color differences; a diagram showing chloride-driven corrosion without phosphates; and a beaker of brownish, contaminated water. Text overlays emphasize more chlorination, more ferric chloride, and no phosphates added.

A slide titled โ€œThe Flint Water Crisisโ€ with an infographic explaining how trihalomethanes formed when chlorine disinfectant reacted with organic matter in Flintโ€™s water. The diagram compares corrosion levels in Detroit vs. Flint water, shows phosphate-based corrosion control chemistry, and illustrates pipes with and without phosphates. Bullet points on the left summarize the causes: organic materials not oxidized, chlorine reacting with organics, trihalomethane formation, and no phosphate corrosion control.

Flint wasnโ€™t just a chemistry failure โ€” it was a community crisis.

Always a pleasure to discuss the wonders of lignin.

Note: itโ€™s not suggested to hug the big ball of Twine in Cawker City KS. Itโ€™s rumored the locals pee on it.

With that said it has over a literal ton of lignin in it.
