Two things that should not be possible to do less often than random, but somehow I always do: put in a USB 2 the right way up, and remember which goes first in R expression(paste()) or paste(expression()).

Pinot-lizing students really ruins the mood for other guests. I hope you’re being Syrah-ptitious about it.

I play this at lunch with colleagues. None of us are good at it.

Ah, I only bought it in Wuhan and price wasn't that bad (I still regretted it).

How do you deal with different library prep effects? We have done something very similar using BUSCO genes and see >50% variation in genome size for the same inbred line depending on what fastq dataset we download from the SRA. My guess is library prep (especially PCR reps) affects repeat content.

It's heavy. It pokes you. It breaks bags. It smells bad... and doesn't taste that great either. Did I mention the smell?

Boo U.S. restrictions, yay PEQG!

Really liked the power analysis you did here to compare methods. Too often we just run some scan and call it a day. Neat work!

1/ So pleased to share our paper on genetic adaptation to micronutrients in humans! Our biggest conclusion? Trace minerals in the diet have shaped human evolution far more than previously appreciated 🧬🌍👇

Agree. However, I do find AI helpful for editing suggestions once I've written something I like. It makes lots of suggestions I dislike, but isn't bad at identifying an awkward phrase, great for picking out spelling and grammar errors I can no longer see because I've read it too many times, etc.

I always say you gotta be honest with trainees about the limitations of your study organism.

Quobyte. We’ve been happy with it. But it’s not for an individual user it’s for HPC scale storage. Happy to chat more if you want gory details.

TFW when your lab's storage setup is so wonky you get used as the case study in a promotional flyer for a company selling a distributed filesystem.

I had to do a double take reading it as my first thought was "that's not the story I remember of the origin of the Miranda Rights"

Second fastest time in 12 years. Just over 45 minutes to get through the maze. In the dark.

Ferns are highly evolved from more basal life forms. One rung below corn on the celestial ladder.

Damn, back in my day we only worried about razors.

I knew I should have paid for the high end library prep kit…

You’d have to be bananas bread to even try. I of course did, with an online aligner, and the browser cookies nearly crashed my computer.

This is why shortbreads are bad to sequence with. They just bounce right off.
