The logic is the same about differences in relatedness.

But I'd avoid it & these 'twin' calculations entirely. Tons of hidden assumptions baked in: dominance, epistasis, G*E, shared environments being equal, interactions between additive effects and any of these, effects of assortative mating...

One of America’s Great Traditions Is Dying. I’ll Never Let It. Not Now That I Have Proof I Was Right All Along. There’s still time to get on the right side of history.

Dan Kois deep dive on … bar soap? Heck yeah

The humble bar of soap used to define the American way. Now it’s dying. I will not let it go down without a fight. slate.com/life/2026/02...

Not genomics, but I **LOVED** a versatile piece of software for matrix operations, life cycles, permutation and randomization testing, and basic stats... PopTools, an add-in for 32 bit Excel on Windows.

It was great for teaching and early students, user-friendly, and efficient.

You've got to put the fact you're an Olympic athlete in the first sentence. No prof is getting that far into an email.

Rittenhouse had a rifle which he brandished, Pretti had a pistol he kept holstered. Rittenhouse shot and killed two people while Pretti didn’t shoot anyone. For that, Rittenhouse became a cause celebre on the right, meeting with Trump at Mar-a-Lago, speaking at TPUSA events, and raising big money.

The ass kissing of Trump by execs of Apple and Amazon and others coupled with ongoing silence from many in the tech and biotech and science areas about ICE and related evil activities is extremely disappointing.

The Spandrels paper should only be read with Mayr's Am Nat response, How to Carry Out the Adaptationist Programme, and of course: Lande and Arnold 1983.

L & A '83 was a direct antidote as far as selection is concerned. It can be measured, correlated traits distinguished, we can do experiments..

Video before it happens is showing this guy they shot in the head in Minneapolis was just standing there videoing them before and they got out to push him back and then murder him.

Super intuitive to have the configuration options spread across 5 locations, with partial redundancy, and some of them opening a web-browser with a slightly different set of options.

I'd like to thank Slack for hiding configuration tools in : 1, the workspace name & its menus; 2, the gear icon next to the workspace name; 3, the Admin gear icon in the left navigation panel ; 4, the three horizontal lines on the top left (on a PC); 5, the question mark icon on the right.

Videos Show How ICE Vehicle Stops Can Escalate to Shootings A WSJ visual investigation found that the Minneapolis ICE killing is one of 13 incidents where federal immigration agents have used deadly force against civilians in vehicles since July.

A pattern of escalating, unnecessary violence:

I have a horrible feeling sometimes that heavily promoted crap research on space aliens, cold showers, mind-body healing, schoolyard evolutionary psychology, extra-sensory perception, magic golf balls, air rage, himmicanes, subliminal smiley faces, etc etc etc, has softened the ground so that the seeds of more evil trees could then be planted and take root. | Statistical Modeling, Causal Inference, and Social Science Dale Lehman sends an email with subject line β€œA new low in science”:
