I study hummingbirds and owls, and the sounds they make, or not, with their wings.

A classic Far Side cartoon featuring two gorillas sitting next to each other on a limb. One gorilla is pulling a hair out of the fur of the other, and saying "Well, well - another blond hair....Conducting a little more "research" with the Jane Goodall tramp?"

RIP to the incomparable Jane Goodall, who embodied the best of humanity.

Her rich legacy included becoming friends with Gary Larson after he drew this cartoon. (She was delighted by it, even though many at the time thought it was terribly offensive to her.)

I always wonder how much the experimental exposure to noise benefits the owl by masking the prey's hearing.

Let’s be clear about what happened to Jimmy Kimmel Trump’s most brazen attack on free speech yet.

After years of complaining about cancel culture, the current administration has taken it to a new and dangerous level by routinely threatening regulatory action against media companies unless they muzzle or fire reporters and commentators it doesn’t like.

Spent hours being spellbound by Convolvulus Hawk Moths last night as they nectared on Nicotiana plants in my highland garden!. Up to 3 feeding at a time, their entire abdomens glowing red hot in the thermal from flight muscle use!! #teammoth @migrantmothuk.bsky.social @savebutterflies.bsky.social

Songbirds play optical tricks to make their feather colors β€˜pop’ Concealed black or white bands on feathers boost the vibrancy of bird plumage

Pick an idiom: "more than meets the eye", "beauty more than skin [feather] deep" etc.

In work led by Rosalyn Price-Waldman, we describe a hidden (and ignored!) black or white layer found below the visible surface of bird feathers which helps make bird colours so striking!

How long can a log remain preserved in a lake? Could any have been there for 1000's of years? any chance of a dendochronology study similar to what they did with bristlecone pines?

They are, but only about 1.5x the work of one. Sometimes they’re both asleep and sometimes they’re both screaming, the moments when 2 = 1

(And if you're asking whether her job at the pizza chain displaced a normal-bodied worker on a 1:1 basis, I don't think so but am not completely sure). I don't know how much useful work they got out of her, surely some. With the cognition of a 6 YO, she's always had a guardian

A person with the cognition of a 6YO does not live independently nor have normal expenses, so I don't know what "living wage" means here. Social security (and her inheritance) support her.

My developmentally disabled aunt (cognition of a 6YO) participated in that program for decades. It kept her busy and provided community/structure. It wouldn't have worked had they been forced to pay her minimum wage. Those trying to force a wage increase are misguided

Strategy needs to be 100% tailored to this specific student, which is why gentle teasing might be better. "ChatGPT, please generate 30 fake citations on [topic] written by [student]", print them out & paste around the lab?

*Sigh*. Caught a grad student using AI to generate fake citations today. Need to figure out the best strategy to make this a teachable moment. Maybe "gentle teasing"? "Strict warning"? Unclear which will work best in this case.

Did they also test whether noise and light pollution alter prey's ability to detect the owl?
