Prove that President Trump and Kristi Noem lied
When they both claimed that Alex Pretti was a domestic terrorist
As the video evidence which they present, shows otherwise

They are targeting children because they are trying incite violence. I have talked to many journalists today, and they all made the same observation: Border Patrol and ICE have been rolling around with maximum aggression, lingering for ages as crowds, gather, seemingly trying to cause a riot.

This is the most astonishing graph of what the Trump regime has done to US science. They have destroyed the federal science workforce across the board. The negative impacts on Americans will be felt for generations, and the US might never be the same again.

We compared deer mice evolved in forest vs prairie habitats. We found that forest mice have:
(1) more corticospinal neurons (CSNs)
(2) better hand dexterity
(3) more dexterous climbing, which is linked to CSN number🧵
