cannot emphasize what a relief it is to have new reference sequences for the newly detected segments this fall, particularly NA protein

I missed this the other day: USDA NVSL finally updated GenoFlu πŸŽ‰

Confirms that D1.1 continues to reign supreme, though there are new EA3 reassortants out there that emerged this fall

We did use lists of names from the excellent PLUM website (woo PLUM Act!), so doing something like this now is much easier than it was 10 years ago, but yes, we need legislation to finish the job.

But this Claude incident highlights another problem with AI:

My story and the Post's work are carefully written and reported.

We deliberately choose what we can and can't say. Editors review our language and challenge us on facts.

AI summaries throw all that work into a copy blender.🫠

one thing i have noticed is a lot of folks do not seem to understand the difference between a presidential election and 435+ legislative elections. i have seen any number of people say that you could subvert the outcome this november by targeting β€œswing states,” which does not make any sense.

I expected the cuts would be bad but I'm honestly stunned and sickened seeing how many great journalists the Washington Post just lost. People who nailed huge investigations, documented war zones, exposed horrific crimes, dropped all at once for failures they did not cause.

Egg layers hit by HPAI in Weld CO, 1.3M birds.

Two Weld County farms above 1M layers have been hit at least twice since 2.3.4.4b arrived in 2022.

An egg layer flock in Lancaster County, PA hit with HPAI this week.

One to keep an eye on: In 2022, when an egg-laying flock in Lancaster around that size had an outbreak, the infection spread to other flocks in Lancaster and Berks, taking out over 4 million birds, mostly layers.

A billionaire known as β€œBitcoin Jesus” was under indictment for massive criminal tax fraud and very likely going to prison.

Then, he hired a β€œFriend of Trump” and the criminal charges disappeared.

How did they do it? Avi Asher-Schapiro and I spent months getting the inside story.

The blue one looks like... Mercator clipped to a circle? With graticules and equator around 25Β°N?

The other one is somewhat orthographic, ALSO clipped to a smaller circle. Maybe. You can't really get the features with a general perspective projection I don't think.

Also, yes, I know. I am aware.
