My PhD student Darshi is first author of the paper refuting the proposed importance of NO3-initiated oxidation of Hg(0) in the gas phase. This paper combines advanced quantum chemical calculations, kinetic analysis, and global atmospheric modeling,

My wife and I took our kids to the local science museum. A staffer poured liquid nitrogen into a beaker and it bubbled. The staffer asked what was happening. My five-year old said "evaporation". Why yes, I am a physical chemist. How did you know?

Idgaf I’m still fighting for guaranteed healthcare.
Aspiration is the answer. Not just “we’re not the bad guys.”
We need something more meaningful than that. I want a future worth fighting for. They have no vision. We do. Lean into our strengths and knock them out. 👊🏽

Screenshot of a tweet from Acyn ((@Acyn) The tweet quotes Vance saying, 'When you don't have the best standards in who you're hiring, it means on the one hand, you're not getting the best people in government. But on the other hand, it puts stresses on the people who are already there.' Below the tweet, there is an image of a person speaking at a podium with the White House seal in the background. The person is wearing a suit and red tie, and there are American flags on either side of the podium. The broadcast is live on C-SPAN2.
We don’t have any standards on who we’re putting in charge of our government now. And that’s putting stress on the people already there.

Senator Sheldon Whitehouse reads the law that allows Kash Patel to give permission to the committee to get a transcript of his grand jury testimony.
Kash Patel goes in circles and refuses to give them permission.
What is Kash hiding?

The discovery of sex chromosomes was just as controversial as everything else in genetics
Nettie Stevens, a former school teacher turned geneticist, discovered sex chromosomes in 1905. Here's her story:
Since the fascists are waging a gender war based on their (wrong) views re: the determinacy of X Y chromosomes, I’d just like to point out that they were discovered by an unmarried woman geneticist whose findings were stolen by men after she died of breast cancer at 50.

Lee Atwater had a pungent and famous quote about how once conservatives could no longer use the n-word they used things like “states’ rights” to invoke the same spirit.
I don’t think it’s an exaggeration any more — if it ever was — to say they use DEI as the n-word.

it's hard to read the chart in the screenshot but what this moron is actually complaining about isn't "DEI" staff, it's special education teachers. these ghouls are coming for people with disabilities and they aren't even shy about it.
