RFK Jr.'s Anti-Vax lies make his dangerous friends stronger. No one wants dangerous diseases. It's time to #ImpeachTheQuack !

It’s been a year since this post. Life is…so different now.

Yet, I’m sitting here on my living room floor, with my cold coffee, in the same robe, playing with my beautiful son. Just like I was when I wrote this.

@standupforscience.bsky.social started with a skeet and an idea.

Three reasons out of many to #SaveNCAR. NCAR keeps us informed for extreme weather β€” and when we are informed, we can prepare. Defunding NCAR leaves us all stranded when it matters the most.

It takes 30 secs to take action to #SaveNCAR. Send an email to our elected officials at tr.ee/save-ncar πŸ“²πŸ“§

Hi. Hello.

AI can't feel. It doesn't experience love. It doesn't experience judgement.

This is like saying a screwdriver with a flashlight on it can "see". AI is a calculator, Amanda.

But hey, the people who's air and water AI has poisoned by existing CAN feel.

I hope this helps.

This is Alex Pretti.

This morning he was murdered by ICE. Six ICE agents held him down and shot him at point blank range. Alex was a nurse and researcher at the VA.

Our thoughts are with his loved ones and we stand united in action calling for the abolishment of ICE.

ICE’s actions tear families apart, intimidate communities, & undermine the conditions that make education, research, healthcare, & public trust possible.

We’re calling on scientists to join the general anti-ICE strike in Minnesota on January 23rd.

Safe to say most scientists, and I think most journalists, disagree with his a view. Good journalism should do its best to represent what science says, rather than treat it as a debate where every view is equally valid and readers just need to figure it out.

 A protester stands outdoors wearing a large papier-mΓ’chΓ© head of Donald Trump and a tall white hat marked with a dollar sign, giving a thumbs-up gesture. They wear a dark coat and a white clerical-style stole with a cross, while protest signs and a Statue of Liberty figure appear blurred in the background.

A crowd gathers outdoors at a protest, viewed from behind, with one person holding a black sign that reads β€œNO HATE” in large blue letters. Snow-dusted mountains and leafless trees rise in the background under clear daylight.

Congress Is Reversing Trump’s Steep Budget Cuts to Science

This is a HUGE win…and one that happened because we ~collectively~ said β€œNO!”

But AAAS coming in and saying on record to the NYT β€œScience is doing ok. Things are not bad at all…” is baffling.

I keep going back to this. This is a taunt. They're taunting us. There is no other possible interpretation of what they're doing.

But media simply ignores this deranged behavior, because if they talk about it, one must conclude that DHS is a rogue agency, of villainous paramilitary thugs.
