“Hack-a-thon” and “taxes” do not belong in the same sentence.
Canada, make sure to keep the Cons out of power so we don’t have to deal with similar stupidities. #canpoli

I don't just want to see Pierre Poilievre and the CPC lose, I want to see them so crushed that no major Canadian party ever flirts with or supports the extreme right again. Every vote against the CPC and PPC matters. Be sure to vote. Send them and the world a message.

Columbia has conceded academic freedom. The subject of, nature of and response to the protests aren’t directly relevant; the US administration is now dictating what the affected departments can research and teach.

Awesome news. Rubin is the scientist perhaps most closely identified with the discovery that galaxy rotation cannot be explained with Newton’s law of gravity applied to the gas and stars they contain. This led directly to the idea that dark matter dominates the gravity of galaxies at large radii. 🧪
Vera Rubin has been selected to be featured on the back of a quarter. She is the first astronomer to be honored this way. Read about her research on the Andromeda galaxy and how it led to the discovery of dark matter in this article written by Rubin herself. doi.org/10.1063/1.24...

Trump's ONLY interest in 'peace' in the Russia - Ukraine conflict is that he thinks it will net him a Nobel Peace Prize. He would be a shoo-in for the Nobel Stupidity Prize if it existed.

I often do not agree with Globe & Mail columnist Andrew Coyne, but he really nails it with “The United States has handed the nuclear codes to a madman, a criminal, a would-be dictator and a moron, all in the same person.”

The first measles death in the US in a decade -- the tragic, preventable death of a child whose parents chose not to protect them with vaccination -- should spark an immediate nation-wide campaign to ensure all children are protected against preventable diseases. Anything less is unconscionable.

Helmut Abt, stellar astronomer, former ApJ editor, and one of the founders of Kitt Peak National Observatory, passed away today at age 99. Helmut played a large role in setting up KPNO, a new concept at the time of a publicly open facility, offering telescope time based solely on scientific merit.
