Often when people see the photo, they think the farmer should be happy - look how green it is!
But plants use light cues to know what season it is. You know the song: "🎶 a time to be born, a time to die, a time to plant, a time to reap... 🎶"
Well, there's a time to burst out leaves, and a time to stop making leaves and start making fruit. And the soybean plants near the streetlight don't realize what season they are in. (2/)
Congrats Matt!

"The revolution in LED lighting has increased the scope of light pollution in the United States. We can combat this pollution as a nation by transitioning to equally efficient warm-light LEDs from the currently in-place cool-light LED fixtures."

"Earth needs darkness just as much as it needs light. But human light pollution is pushing back the dark, which is changing the natural world, and could be hurting us, too."
WBUR 'On Point' podcast episode featuring several prominent dark-sky folks:
Approximately 24,100 school board seats in 35 states are up for regular election in 2023.
The 24,100 seats up for election represent 29% of all school board seats in the country.
And the MAGA Fascist GOP want their folks in those seats.
Never get tired a this un...
"Years ago, anthropologist Margaret Mead was asked by a student what she considered to be the first sign of civilization in a culture. The student expected Mead to talk about fishhooks or clay pots or grinding stones.
But no.
Mead said that the first sign of civilization in an ancient culture was a femur (thighbone) that had been broken and then healed.
Mead explained that in the animal kingdom, if you break your leg, you die.
You cannot run from danger, get to the river for a drink or hunt for food.
You are meat for prowling beasts.
No animal survives a broken leg long enough for the bone to heal.
A broken femur that has healed is evidence that someone has taken time to stay with the one who fell, has bound up the wound, has carried the person to safety and has tended the person through recovery.
Helping someone else through difficulty is where civilization starts, Mead said."
We are at our best when we serve others.
Be civilized.
I do a lot of #OTD posts, but sometimes it’s hard to find reliable info about an obscure scientist.
This is my annual plea for help with theoretical physicist “Albert Einstein,” born #OTD in 1879. His contributions are minor but still of some interest to me personally.
You may have seen his work attributed to "Alfred Einstein,” "Albert Eisenstein," or similar. Any help you can provide digging up info on this little-known scholar is much appreciated.

Artificial light at night disrupts plants' "seasonal rhythms, their ability to sense and react to natural light, and their fragile relationship with pollinators. The more strained that relationship becomes, the more our food supply may be put in jeopardy. And just one broken link could create unfathomable physiological consequences up and down the food chain."
