Cats were domesticated about 10,000 years ago, when wild cats encountered the first human settlements and saw an opportunity to constantly be in the way

So cool! (literally, lol)

Some of the best discoveries are fortuitous. Chemists modified an antibiotic (vancomycin) targeting gram-positive bacteria to make it more effective against resistant strains. In doing so they unexpectedly made a form of vancomycin that also kills gram-negative bacteria #science #medicine #chemistry

Some quick Powerful Owl sketch experiments. Every drawing is practice for the next.

Dr Hoffman was a nuclear chemist who was often the only woman in her chemistry courses. She earned her doctorate in 1951. #womeninscience #womeninstem #science #chemistry

Happy Thanksgiving, Bluesky!

Beautiful day for a hike along the Appalachian Trail in VA. The views looking west were beautiful, but the nearby trees stole the show. #mobilephotography #nature #trees

Here is a short Q&A thread on #COVID and #Flu vaccines for the upcoming respiratory virus season. I try to cover frequently asked questions. The good news is both vaccines will be available this fall though we need clarification on access to COVID vaccines for healthy folks <65. A 🧵

Jellyfish at the Seattle Aquarium. So peaceful to watch, when there’s no chance of getting stung lol

Went for a hike this afternoon to see the Potomac River, and it did not disappoint. A mushroom I spotted along the way was doing its best impression of a carnation. #mushrooms #hiking #river #wildlife

Happy birthday to #astrophysicist Jocelyn Bell Burnell! 🧪🐡👩🏼‍🔬🎢🔭#histsci In 1967, as a grad student she discovered the 1st radio pulsar, a highly magnetized, rotating neutron star that emits a beam of EM radiation. This radiation can only be observed when the star is pointed towards us; so, like the

Wow… what I wouldn’t give to have a car free lifestyle 😭

🗣️ FOLKS! We’ve got a Zipper Bird on our hands here. This guy tends to be a tree-topper, and makes really cool hanging moss nests. A quintessential Adirondack bird! Do you recognize this song? #AwesomeBirds

I'm repeating this as dogwoods are more broadly in flower. On the left with white bracts (not petals) is a flowering dogwood inflorescence, containing many flowers. The closeup shows the individual flowers. We can learn a lot just by looking at nature carefully.

Not to pile on, but every 'c' in 'Pacific Ocean' is pronounced differently.

This is a fascinating thread, and yet the era of box beds wasn’t exactly ancient history. Can’t help but wonder what other customs have been lost to time.

What can you learn about an owl from their piercing eyes? There /seems/ to be a correlation between iris eye color & activity cycle. Owls with YELLOW eyes are more likely to be 'diurnal': day-hunters, as with this Northern hawk-owl (Surnia ulula) which hunts, like a hawk, in the daytime.

Merry Christmas, Bluesky

During World War 1, fighting temporarily ceased in the trenches for Christmas and some German troops put up a sign meaning God with us – GOTT MIT UNS. The British troops then crawled across no-man’s land and wrote their own message on the German sign – WE GOT MITTENS TOO

Complex, interesting oil paintings are hanging in my studio unfinished. They are unique; my own style. My favorite way to blend science + art. I love them and will get back to them eventually. But right now I’m captivated by painting planets on little pieces of clay. 🐡🔭🧪

Came across some urban chickens yesterday and couldn’t help but laugh at the white one. I believe it’s a Polish chicken, with its large crest and beard. #birds

We have a very little advertised Phone Photography feed which definitely deserves more attention and participation.

(Finally) escaping twitter reminds me of this mystic I once read who said that the gates of hell are always open for those who are ready to leave.

The other day I was busy working at my desk but I kept hearing the neighbors’ dogs barking. I finally looked outside - a Cooper’s hawk was calmly sitting on a fence post, knowing full well that the dogs could see him but not reach him. If it’s possible to troll dogs, this bird was doing it #birds

Agree! Don’t forget about shingles if you’re 50 years old or older.

I never need to look outside to know when a corvid is visiting the feeder. They love the sound of their own voices… at full volume 📣 #birds
