Please excuse a non-nature post. This is happening now to bring awareness to Long Covid. I've been watching for half an hour and already learned a lot. Dianna Cowern is an incredible science Youtuber who's been in bed with Long Covid for almost two years. Hosted by Simone Giertz & others. 🧪

Went to a clinic today for a routine medical thing and was once again amazed by the number of people who are happy to hang out and just freely breathe in all the air juice inside the germ emporium

I still think this and I try to keep it in mind even while 80% of my feed is people expressing outrage and vitriol at anyone who isn’t wholeheartedly promoting some specific opinion about the best path forward for the world

I really do believe that most people are basically good, mean well, and want to have a positive impact on the world

something very John Green / @astrokatie.com about the latest Dinosaur Comics

Happy 4th of July! In the wise words of Ben Franklin: The Bald Eagle is a Bird of bad moral Character. Too lazy to fish for himself. The Turkey is a more respectable Bird, though vain & silly, a Bird of Courage, and would attack a Brit who should presume to invade his Farm Yard with a red Coat on.

lol someone is impersonating me (please block and report if you see them)

@astrokatie.com Dr Mack is this a second account or an imposter?

Got a haircut. Looking fabulous. No I will not be providing any evidence for this claim, you must rely on your faith in my unimpeachable honesty and use your imagination

Part of a good thread that illustrates why I don’t hang out on Twitter/X anymore

There was an even bigger difference in the comments received. All on Threads and all but one here were positive, constructive, or neutral (one person was just being a jerk, not a troll). Only 18% on X were positive or neutral. The rest were negative, many highly so.

Yesterday, I shared this same Canada Day thread on Bluesky, Threads, and X. Here's what I found. 🧵

“Canada is such a northern country, don’t we want a little global warming?” I often hear. In a nutshell, NO. We’re warming 2x faster than the rest of the world, driving extreme heat, flood, and sea level rise we are not prepared for. The wildfire season started in Feb this year. Feb! #canadaday

Canada’s Changing Climate Reportchangingclimate.ca

Keeping Trump out of the White House isn’t the only thing that needs doing and it isn’t enough to solve all problems facing the country & world but if it isn’t done then all those problems get exponentially worse in ways I don’t even know how to express and it scares me when people pretend otherwise

I kinda feel like now that the Supreme Court has declared it legal for a president to straight-up murder people they don't like, it's probably even more important to not elect people who seem extremely inclined to murder people they don't like

🇨🇦 Went for a Canada Day walk this morning with @vriccithode.bsky.social and her pack 🐾

roberts’ reasoning is fundamentally (lower-case “r”) anti-republican. i know we dunk on the framers here but roberts has issued a rebuke of the revolutionary assumption that concentrated, unaccountable power is a fundamental threat to liberty.

It's just hilariously disingenuous. Imagine looking at, say, ALL OF HUMAN HISTORY and concluding that the biggest threat to liberty isn't abuse of power, but powerful people refraining from sufficiently wielding their authority out of fear that they might one day be held accountable.

When you think about it, it's ridiculous that "annoy people until they give you their money and/or data" is the default business model for so much of the internet now.

Absolutely infuriating that we have no infrastructure to notify the population of these trends. City public health departments should be monitoring local wastewater and sending alerts to the entire population when it crosses a specific threshold.

Just FYI we’re entering a summer Covid wave right now (especially western regions in the US); you can see it in the CDC wastewater plot here (and anecdotally a bunch of my friends are suddenly testing positive). www.cdc.gov/nwss/rv/COVI...

Getting the strong impression that all of California is just one big covid soup at the moment 😬😷

Woke up this morning and wasted an entire half hour of what remains of my life posting about the debate and election when I could have been looking at a plant or something. Deleted everything so I would stop reading/replying to inanity and went for a run instead. Learn from my mistake, friends.
