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/)
We once had Bob Crelin (author of There Once was a Sky Full of Stars) as a guest speaker. He had photos of trees that changed color depending on whether thy were facing a lighted billboard or not. Very eye opening for students.
@SarahMackAttack What street? Will look for progress on my next trip there.

The outrage over security from TikTok might be taken a bit more seriously if we didn't just watch Facebook admit to enabling Rohingya genocide, help to manipulate the 2016 election, cause massive PTSD to its own employees, and face zero meaningful accountability whatsoever.

@lowqualityfacts In his late dementia days my dad loved Dennys. Service was fast and they had wine.
@jnthnwwlsn Won't kids wonder why she was sent to the back? Will teachers be able to answer?

The same people who cry “politicization” over charges around a porn star hush money cover-up designed to swing a national election brought perjury and obstruction articles against another president for lying about a blowjob.
Spare me the sanctimony and hypocrisy.
@maria At the time I wondered how anyone would accept without question the words of a guy who acted for a living.
@ksaj @nasapics_bot I dunno those look a lot like fangs. It was much less detail that led to the "face on Mars speaks" mania. What would Globe make of this?

"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."
