This is so incredibly heart-breaking. To Jay Bhattacharya and Matthew Memoli at NIH--you have betrayed the entire scientific community. Deeply committed staff are leaving in droves--because you are destroying the institution. Shame on you. www.statnews.com/2026/01/10/n...
The NIH has lost its scientific integrity. So we left
“We can no longer lend our credibility to an organization that has lost its integrity,” write four scientists and administrators who recently resigned from the NIH.

Editorial in the National Catholic Reporter: "The vice president's comments justifying the death of Renee Good are a moral stain on the collective witness of our Catholic faith. His repeated attempts to blame Good for her own death are fundamentally incompatible with the Gospel."

Today marks 5 years since Trump incited the deadly attack on our Capitol.

Ever since, Trump has tried to downplay January 6, pardoning the rioters who assaulted brave law enforcement officers.

We must continue to defend our democracy and never let this history be erased.

Email from Chat GPT folks is a bit, well, creepy given how AI Chat Bots acvtually can do serious harm.
You don’t need a plan or the perfect question to use ChatGPT. Just start typing whatever’s on your mind — a half-baked idea, a random question, a weird "what if." ChatGPT is built for all of it. No pressure. No perfect prompts. Explore ideas, create images, write stories, and summarize files in just a simple conversation. Best, The ChatGPT Team
