Apple has removed an ICE tracking app that allows users to report ICE activity nearby from its App Store.

The removal came after a direct demand from Trump’s DOJ.

Once again, Big Tech is bending the knee to our tyrant-in-chief to protect its bottom line.

Logan Square neighborhood, Chicago. Man wearing a balaclava in a white, unmarked vehicle, pulls the pin on a tear gas canister and tosses it in the road.

Among them, a Poretsky Lab alum whom we miss very much here in Chicago (but are so excited for.)

Hi, Pete Hegseth. It’s me. Army veteran, Judge Advocate lawyer, and law professor. Your vain and gross performance to our nation’s military leaders succeeded only in proving your incompetence, dangerousness, and childishness. You’re a petty spoiled 7th grade boy without the sophistication or class.

NSF GRFP is out 2.5 months late w/key changes

1. 2nd year graduate students not eligible.

2. "alignment with Administration priorities"

3. Unlike prior years, they DO NOT specify the expected number of awards... that is a BIG problem.

Only an administration intent on committing war crimes in the present and future would stoop to calling Wounded Knee a "battle" rather than what it truly was: a massacre of over 250 Lakotas, mainly women, children, and the elderly. 1/

So if Jimmy Kimmel had just suggested killing homeless people by involuntary lethal injection, like Brian Kilmeade did on Fox, he’d still have a job?

TERRORISM EXPERT HERE:
He cannot designate an idea as a terrorist group.

There is no org called ANTIFA. There is no leadership or funding path or no membership. Also there is no terrorism law in America. Ask Luigi.

He wants to call anyone a terrorist. That’s Fascism.

I did lab work and didn’t hurt myself or break anything. I did, however, have to constantly ask the labbies where things were.

And, turns out, 1) pathogens don’t care about state borders and 2) people travel to/from FL sometimes.

Scenes from the nightmare hellscape that is Chicago!
Chicago slyline at Grant Park starting point for Bike the Drive. Hmmm. That Revolution Brewing banner gives me an idea for topping up my carb intake. Bicyclists headed south. Bike the drive bikers with Field Museum in background. Riders of all shapes, sizes, and ages. See #3 alt trxt.

So gross. Starting on the front page, too, along with an article about durian. As if there’s a shortage of news to report on.

Dr. Dmitri Daskalakis, who resigned from the CDC says that RFKJr said he believes that Avian flu should be allowed to "burn through" the chickens and then children and others, so we can propagate a "stronger species". RFKJr believes in eugenics.

RFKJr needs to resign or be fired.

It bears repeating that nearly the entire US enterprise in science and technology has been irreversibly gutted. This is shocking.

All this loss has occurred without any real benefit to the average US citizen. Except we now have the biggest, best funded secret police force perhaps ever.

Yay for us!

Multiple ecology faculty positions at @notredame.bsky.social. Apply at apply.interfolio.com/171650. (1/2). 🌎🌐🧪
Multiple Early Career Faculty Positions in Ecology
 
The Department of Biological Sciences at the University of Notre Dame invites applications for multiple, tenure-track assistant professor positions that will enhance existing institutional excellence in ecology. We are searching broadly for creative and collaborative individuals (1) working at any spatial scale, from local to global, in any system, (2) studying any level of biological organization, from genes to ecosystems, and (3) using any mode of inference, from empirical to theoretical. Applicants should demonstrate research excellence that crosses traditional disciplinary boundaries; ongoing growth in the department will emphasize new hires that use quantitative and/or integrative approaches to study ecological processes. Postdoctoral experience is desirable in applicants. Successful candidates will engage with and benefit from UNDERC, Notre Dame’s 8000-acre environmental field station and home to NEON’s Great Lakes domain, superb on-campus chemical and genomic analytical facilities, an experimental research facility located close to campus, cross-disciplinary interactions through multiple centers and institutes including the Environmental Change Initiative, and a unique Interdisciplinary Graduate Training Program in Environment and Society. New faculty will benefit from Notre Dame’s recent campus-wide Strategic Framework that included the Just Transformations to Sustainability Initiative. Modern research facilities exist in a new environmental research building, which opened in 2025.
