We captured 18 birds today and then we surveyed the colony for bird flu, which we thankfully saw no evidence of.

Oh, I love this. A new species of sea anemone was discovered recently that parks itself on top of a hermit crab shell like a hat. It seems to feed partly off the crab's faeces, but it also excretes a hard shell that extends the crab's home. In return, it's carried around the seafloor like a king.

I am seeing a lot of posts about Rosalind Franklin that themselves ignore her publication record on DNA!
In fact Franklin and Gosling's paper, including the famous Photograph #51, was published, along with Wilkins's paper, back-to-back with the Watson and Crick paper in Nature in 1953.

A Sharon Begley byline, almost 5 years after her death.
Upon hearing the news James Watson had died, a STAT reporter said in our Slack, "I wish I could read what Sharon would have written."
Incredible news: Sharon in fact did pre-write a Watson obit. And it is masterful and excoriating.

I've said it before: everything giant pandas do makes more sense if you imagine they are six drinks in on a Friday night.
But I feel like we haven't fully celebrated their triumphant return. See, the giant panda (Ailuropoda melanoleuca) is no longer Endangered.
A conservation success story!

Alt: a panda bear is sitting on a wooden platform with toys, it barrels through them, falls, and manages to roll down every part of the stairs, as if on purpose. Just agent of chaos behavior.

Shy-Hulud was awake, so I gave them a sliver of mango, and that's the quickest (relatively speaking) I've ever seen them go for a snack. 💛
