short and sweet episode. I've heard the word "perovskite", but the difference in cost is a real leap

This morning, a bit less than two hours in the Ramble yielded 33 species. Nothing new--I missed the reported Spotted Sandpiper--but I did see my first Ovenbird and Common Yellowthroat of the year (I had only heard them singing before).

A late-afternoon stroll in Carl Schurz Park had my first Barn Swallows of the year, around their usual nest site at the ferry dock. Only two so far, but that will pick up.

At least 20 Double-crested Cormorants nests on Mill Rock, with 44 birds.

I was today years old when I learned that there may be a relationship between pollen counts and viral respiratory infections. Pollen impairs the immune response to viruses, and viruses may also be able to hitchhike deep into the airways on pollen grains. High pollen concentrations in March 2020 may have facilitated the spread of COVID during the first pandemic wave 🤧 :virus:

Our #JWST rocky exoplanet team is back with a new result:

Water Vapor in the data of warm rocky planet! 💦

But is it from the planet's atmosphere or cool star spots on the star?? 🌎 🤔 🔴

Happy birthday to #neurologist Santiago Ramón y Cajal (1852 - 1934), here in front of Purkinje and granule cells from a pigeon, based on one of his own drawings! Cajal &Golgi won the Nobel in 1906, "in recognition of their work on the structure of the nervous system". He was as much of an artist as he was a scientist & his 100s of drawings are still used for teaching purposes.⁠

why does everyone seem to have such a defeatist additude about their data being harvested by apps and websites? i always hear people say how "it's probably all out there anyway" or "there's no way to completely prevent it, so i'm not going to bother partially preventing it", the more companies and organizations that spy on you, the more likely you'll be part of a data breach in which some personal information could be released about you. it's good to minimize your online footprint as much as possible.

I can confirm that they're roosting above my door. I stepped out to put my trash in the bin last night and peeked one of them there. before I'd see one in the nest and one nestled in these little plastic needles (which I think are supposed to deter birds🤔), but I only definitely saw one last night

"On 3 separate occasions during the fall and winter, reporters witnessed Norfolk Southern trains blocking intersections leading to an elementary, a middle and a high school for 4, 6 and 7 hours. @ProPublica and InvestigateTV showed footage of kids making the crossing, including an elementary student crawling under a train, to representatives of Norfolk Southern, lawmakers and Secretary of Transportation Pete Buttigieg, whose remit includes rail safety.

He was shocked."

Here's some shots of an incoming thunderstorm over Lake Crabtree in Cary, #NorthCarolina about an hour ago. Living dangerously with a non-weatherproof camera... thankfully I got it into the bag in time. #Photography #Fujifilm
