Bird of the Year voting opens tomorrow, and it is an outrage the takahē is yet to win. I'd like to take this opportunity to urge you to vote for the hide-and-seek legend from Fiordland, the roundest birb, and the one true pick for all you railfans out there
It’s Bird of the Year time, and the official railfan option is the MIGHTY TAKAHĒ, the largest living member of the rail family of birds
So when you vote, don’t forget to include the takahē in your top five: birdoftheyear.org.nz

(4) [Chaotic:] PROFESSOR: No. The wavefunction collapses when *I* look at it because I’m a full professor.

AGU is deeply disappointed in SCOTUS decision to overrule the order blocking the dismantling of fed agencies until we could make our case about the President’s unlawful actions.
The harm this will cause is shocking. However, we will continue to fight for the rule of law.
