Our federal tax dollars are being used to fund a network of government social media accounts that pump out disinformation 24/7. Even during a government shutdown. It’s definitely not essential work.

My dad passed away last week. He endured years of chronic health challenges stemming from Crohn's disease and, later in life, battling blood cancer amongst other health challenges. He was the definition of quiet strength and persistence. He will be missed.

I appreciate, "A PhD is marathon, not a sprint," but it's not a race at all.
To me, a PhD is a hike (with no trails) up a tall mountain in the distance. The end goal is clear, but the journey is long, dynamic, unique, entirely your own, and itself more important than any milestone.

Not really an overstatement to say that the test of a free society is whether or not comedians can make fun of the country's leader on TV without repurcussions.

Glad to be part of this wonderfully written article by @meghanbartels.bsky.social along with @saverygo.bsky.social and others on the devastating & unseen impacts of HPAI on wild birds and mammal populations. So many species are still being impacted by mortality and this virus is not going away.
