OK @calacademy.bsky.social, saw this DNA sequence in an exhibit today, assumed green=A, blue=C, red=T, black=G, and tried to BLAST it to figure out its origin but have so far turned up nothing. What species and gene is this sequence from? Claude didn't know either.

You say I’m trying to poison my lab with ammonium chloride. I say I’m just offering up some Finnish treats.

Got to listen to "Ode to Joy" played on an accurate replica of these 2500 year old bells. It was pretty friggin' awesome. en.wikipedia.org/wiki/Bianzho...

Brilliant use of gfp-tagged transposons & automated scoring of kernels, combined with differential style-lengths along maize ear, to screen for genes underlying pollen competition in maize. Diana gave a banger of a presentation on this in #Zeavolution this morning. www.biorxiv.org/content/10.1...

thank you! we have even better evidence for it now -- even distance to gene shows the MAF enrichment I'd expect from stabilizing but not purifying selection

remembering my most epic wildlife photo ever. this was not staged, we came across this on a trail. just bananas.

Imagine: you are visiting a colleague's office, or a conference room, and you want to explain something. You turn to the chalkboard and <GASP> you are struck by the sight of this. CAN YOU EVEN DO SCIENCE WITH THIS? Unlikely. Better to be prepared.

Wait you mean not everyone brings their own chalk with them when traveling abroad? (I even had a backup, having gifted the colleague I’m visiting a box of the good stuff last year)

Oops, just caught this goof on our preprint. I'm gonna pretend we did that running title tongue-in-cheek on purpose because we're so clever.
