Everytime I open the CMS page for next semester's BI111 sections, my heart skips a jump when I see how many students are enrolled this year!

If at precisely 11.35am on New Years eve you start working on your slides for next year's course, as the clock chimes for new year you'll still be working on your slides.

I want to print YOU DON'T GET GOOD AT A THING BY NOT DOING IT onto little cards and just hand them out in conversation sometimes

D1) again, this is difficult to pull off at longer lengths. But you don't get good at a thing by not doing it.

E) YOU DON'T GET GOOD AT A THING BY NOT DOING IT done is better than perfect. Don't worry so much about "practicing right" just practice. You can adjust as you need as you go on.

A #ScienceAdvances study has found that the coelacanth—an evolutionarily ancient fish often nicknamed a living fossil—lacks 11 jaw muscles that researchers previously thought it had. https://scim.ag/4shX82H
Coelacanths illuminate deep-time evolution of cranial musculature in jawed vertebrates
Revised coelacanth cranial muscle anatomy reveals previously unknown evolutionary innovations and redefines gnathostome muscle evolution.

31 December 1995. Still the perfect goodbye.
The final Calvin and Hobbes cartoon. The entire page is mostly white as they're in the winter snow. The pair is walking with a sledge, nicely duffled in in scarves, hats, gloves. Calvin delightedly exclaims 'wow, it really snowed las night! Isn't it wonderful?'. Hobbes follows up with 'Everything familiar has disappeared! The world looks brand-new!' -- A new year... a fresh, clean start!' adds Calvin. As they look over the landscape, Hobbes observes 'it's like having a big white sheet of paper to draw on!' -- 'A day full of possibilities!' Calvin affirms. They get ready on their sledge and Calvin tells his friend 'it's a magical world, Hobbes, ol' buddy... let's go exploring!', and the pair sledges off into the wintery landscape.

There’s nothing wrong with common sense until you dig a little and learn that common sense is wrong. Thanks @profgalloway.com for providing a great example of common sense that I’ve gotten a kick out of doubting. Thanks @prosocialworld.bsky.social for hosting.

before I started my lab, I asked several senior PIs what their one piece of advice would be and PI pointedly said: “Know when to drop a project.” And that advice has been invaluable in my lab. There are always other projects to follow up on, dropping one isn’t a failure in and of itself.

Stanek et al. studied the Drosophila "dot chromosome” to investigate chromosome-specific size expansion, focusing on four species whose dot chromosomes are 2- to 15-fold larger compared to D. melanogaster.

I don't know who needs to hear this, but opposing GenAI is not about opposing technology, it's about opposing capitalists.

GenAI is not a technology: it's a massive automation of theft, masquerading as an industry, run by grifters.

Don't hate computers, hate the capitalists behind the curtain.

Just watched the new Knives Out and I think it's really important you know that the scene in the Seminary's Gym is filmed in the same place Rick Astley filmed the music video for Never Gonna Give You Up.

I saw the window tracery and immediately made my friends pause the film so I could tell them.

Richard Lewontin on being raised "not as an evolutionist but as a population geneticist"
RL: What we have to decide is whether we’re going to put behind us certain motivations, one of which is the general motivation to struggle against religious anti-evolutionary views, and at the other extreme to be as individuals successful as evolutionary biologists by giving an explanation of something interesting even when we don’t have the observations. I was raised not as an evolutionist but as a population geneticist. DSW: Right. RL: That’s a big difference. DSW: Why is that a big difference? Let’s clarify that for me. I tend to see it as a small difference. What’s the difference between being a population geneticist and an evolutionist? RL: A population geneticist by theoretical training has certain parameters of population change. That’s become broadened by the realization that there are between population changes and so on, but within a population we’re talking about changes in gene frequency and we have a catalog of the causes: selection, inbreeding, chance, mutation, and so on. Our job as population geneticists is to do the necessary observations of the various things that give us estimates of the strength of those different forces. Now, historically one of the most interesting—now I want to talk a little about the sociology of our science—Theodosius Dobzhansky, my professor and then greatest living evolutionary biologist…
