My life changed when I first read "The Sea Around Us." Rachel Carson's words captured my 13-yr old sense of wonder for a place I barely knew but felt for so deeply, the ocean. Honored to speak to her legacy @agu.org and grateful to my colleagues for the nomination 🌊💙

🧑‍🌾 @timmiller.bsky.social on the Trump FARMER BAILOUT: “Tariffs caused a trade war, farmers can’t sell… and now you and I will have to pay them. The stupidest policy I think I’ve ever seen. A land speed record for policy disaster.”

The very tariffs he said would help them are killing them.

Trump says he’s authorized Hegseth to use “Full Force” against Antifa in “War ravaged” Portland
At the request of Secretary of Homeland Security, Kristi Noem, I am directing Secretary of War, Pete Hegseth, to provide all necessary Troops to protect War ravaged Portland, and any of our ICE Facilities under siege from attack by Antifa, and other domestic terrorists. I am also authorizing Full Force, if necessary. Thank you for your attention to this matter!

Our president thinks that asking faculty and staff to voluntarily quit is a better solution than advocating for restoration of our mission funding from SUNY and being a more effective fundraiser. Meanwhile her high-paying job is safe.

How can you help us?

There is! Our arsenic life paper has has an editors note on it for nearly 15 yrs explaining that subsequent research had called our original results into question. That’s why the retraction seems both redundant and mean spirited.

Precisely why a powerful editor should not be retracting peer-reviewed no-misconduct articles 15 yrs after the fact just to score political points and attention. science is messy, and even wrong ideas can help lead us to better ones.
