Each year CIMMYT has a competition in the town of Jala for the longest ear. They're not quite at 48 inches yet, but getting there.

I had a Pokemon that did that once.

Distressed to see I guess I'm out of a job. AI has figured out everything there is to know about maize domestication. (Found this online when looking for images for a talk)

Family popover recipe turns 100 soon. I make it almost every weekend, with only the changes suggested by my grandmother (handwriting).

Heck no, I'd be a collider that was biased as heck, just to be a pain.

I once met the dad of another kid in our childcare who was surprised that my baby daughter had cried when she saw him. As he looked down at me (he's 6'10") he said "this happens often but..." and he thought for a moment as if debating what my 6'5" frame was worth... "you're not a SMALL man".

Heck I might have to convert to catholicism in that case.

In his defense I'm several decades older and I would do the same.

As a fellow atheist I still haven't decided, but he's gaining ground on Francis for sure.

Maybe not Jeff Bezos’s Whole Foods but your local co-op wouldn’t surprise me.

Correlation as causation is such a silly misconception. Everyone knows its correlation squared.

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.

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 🧬🌍👇
