She is not related to Michael Keaton. Interestingly, that's also not his birth name. He too changed his name because his birth name was already registered -- to Michael Douglas.

Interesting trivia related to Diane Keaton. She was born Diane Hall but changed her name to avoid collision with another Diane Hall in equity registry. It's interesting that she became so well known for her role as Annie Hall, returning to her birth name.

The geology professor in the office next to me got me a banded agate that was cut as a sphere making it look like Jupiter! It’s awesome. 😎

For those that would prefer a test where they both had the same number of parts. Wouldn't you prefer that maybe the top and bottom would have the same number of points (and maybe top is better)? Doesn't this create headaches explaining partial-credit scores to students?

Some would argue that the matching problem on top and the multiple-answer problem on the bottom should receive the same score, but #Instructure does not. Rather than choosing one convention for how to score them, #CanvasLMS decided to just use two different conventions...

Weevils aren't known for being noisy, but some do indeed chirp like some of their insect cousins. A new study examines the acoustic signals of soybean weevils to shed light on how they signal each other for mating or emitting distress calls.

For those very disappointed in the news about the #NSFGRFP yesterday (2nd year PhD students excluded), don't forget to look into #NDSEG, which is actually a little better fellowship but just requires connecting to a DOD theme. 🧪

It's like a Lenz's Law but for transcription factors.

"As such, TFs are predicted to have an innate property that buffers physiological or genetic perturbations to the promoter to maintain a steady level of regulated expression. We demonstrate this buffering across all TFs studied."

Our campus is reviving their chapter of the Society of Women in Marine Science. I've offered to help fund raise for them.

Anyone want to contribute? Even a small amount can help at this point, they are starting from zero.

Cripes, the things we humans can do when we look up to the sky instead down into the depths of hatred and internalized bigotry. The whole goddamned cosmos is out there waiting for us to understand it, but we're too busy trying to make life miserable for others on this isolated speck of dust.

Found this (new?) setting in the Course Accommodation settings in #CanvasLMS. I can understand giving students more time, but randomly dropping an incorrect answer from all multiple-choice questions?! How does someone determine that THIS is the right accommodation for anyone?

There are neurosymbolic techniques that couple knowledgebases in to aid in computer vision tasks (e.g., Logic Tensor Networks). I wonder if these would end up having similar effects as the humans if the knowledge became particularly salient in shaping the rewards during training.
