1. It was not an accident.
2. It was not a staffer.
3. While the president may have dementia his racism is not due to dementia.
4. He isn’t sorry. He means every racist thought he shares.
5. His base agrees with him.
6. He will do it again.
7. No one in power will hold him accountable.

Tonight at 8:30 PM our constituent Ricky was pepper sprayed by ICE on 18th & Polk. 2 agents parked their car, got out and approached observers, started pepper spraying Ricky on public property, and then drove away and left.

Nothing is changing on the ground in Minnesota. ICE must be abolished.

Result from the Joggins Formation #paleostream! This Canadian site is an absolute classic and even if you are not familiar with its name you probably know at least one of its major players...

Prepping for quals feels like studying for the SAT and applying for grad school coupled with studying for a calculus final all at once

From 1,750–2,000 m deep, we collected one of the rarest deepsea fishes out there: a one-jaw eel (family Monognathidae). Only ~100 specimens of this group are known worldwide and we hold the largest collection (~46), most just a few inches long… The one we collected though, 6 inches or 154 mm!

Disc-shaped fossils with concentric grooves scattered through a limestone block.

Disc-shaped fossils with concentric grooves scattered through a limestone block.

Image of the apex of the Great Pyramid, taken from the base of the southeast corner. The layers of massive blocks of limestone composing the pyramid are clearly visible. The pyramid is set against a sunny blue sky.

I've seen fossils in some remarkable places, but this takes the prize: the benthic foram Nummulites in the base of the Great Pyramid of Giza. These massive blocks were quarried from the Eocene Mokkatam Formation when a relictual population of woolly mammoths still lived on Wrangel Island.

I always recover well-dichotomized trees that agree with molecular relationships, except for when I don’t, which is most of the time

After having spent a Very Long Time on a project using maximum parsimony analyses on morphological data I can assure you that the results you get are Real and Not Impacted By Bias At All

If anybody out there is like, β€œkids so young would never do this without adult prompting!β€œ

1) you really don’t know kids

2) when Reagan met with Gorbachev, I was in 5th grade & still managed to get my class to sign an anti-nuke petition

Don’t underestimate how much the kids are paying attention

A bowfin (fish) closeup in an aquarium. It appears to have a concerned expression on its face. Probably because Minnesota is currently occupied and there’s a lot of other crazy stuff happening.

Having an amazing time at Mansoura University Vertebrate Paleontology Center. Great to catch up with old colleagues and meet new ones. Thanks for hosting me on my first (but certainly not last) trip to Egypt! πŸ“Έ: Hesham Sallam

Wise words from WEB DuBois to gird us today: "It would be shame and cowardice to surrender this glorious land and its opportunities for civilization and humanity to the thugs and lynchers, the mobs and profiteers, the monopolists & gamblers who today choke its soul and steal its resources."

Minneapolis protester as he's being brutalized by feds: "You're gonna have to kill me! You're gonna have to kill me! I've done nothing wrong! My name is Matthew James! I'm a US citizen! You're gonna kill me! Is that what you want?" (You can hear his wife screaming)

There is a video from across the street of half a dozen or so masked federal agents wrestling a man to the ground, punching him. Then there is a shot, then several others, until he is lying completely still.
You may want to be cautious if you don't want to see the video.
