I don't want a pickle . . .

Jonathan Eisen @phylogenomics.bsky.social · 6h

Though the dump was closed - I found a place to dump the garbage - off the side of a side road there was a cliff and at the bottom of the cliff there was a pile of garbage. I decided that one big pile was better than two little piles, and rather than bring that one up i decided to throw mine down.

I could say I found your name on an envelope at the bottom of half a ton of garbage.

But the real question: Kid, have you rehabilitated yourself?

Seen while on a walk today. Checked Google Maps. This is half a mile from railroad tracks.

Hand written sign in yard that says, "Walk right in, it's around the back"

And I have continued my annual tradition - trying to drop garbage off at the local dump on Thanksgiving - but it was closed again - who ever heard of a dump closed on Thanksgiving?

Jonathan Eisen @phylogenomics.bsky.social · 11h

In honor of Thanksgiving here is a link to my 194 Wild Turkey observations on @inaturalist www.inaturalist.org/observations... #birds

A ton to be thankful for -- here is one part of that - all the acknowledgement sections from my scholarly papers

A blog about microbiology, genomics and metagenomics, sequencing, evolution, ecology, and open science.

Hitting refresh on biorxiv for a paper to appear... realized my first biorxiv preprint was more than 12 years ago, and on arXiv two years before that! Preprinting sure seemed strange at the time, but it's become my favorite part of the process!

This bright orange life-form could point to new dino discoveries

Colorful lichen living on dinosaur bones reflect infrared light that can be detected by drones, which might lead to finds in remote areas.

So happy to announce our new preprint, “A geothermal amoeba sets a new upper temperature limit for eukaryotes.” We cultured a novel amoeba from Lassen Volcanic NP (CA, USA) that divides at 63°C (145°F) 🔥 - a new record for euk growth!

1/ ⚠️ Breaking: At CDC, we've been told the US Government will not officially commemorate World AIDS Day this year. No explanation given.

Photograph of a printed guidance memo stating that the U.S. Government will not be commemorating World AIDS Day this year. Key points include: USG funds should not be used for related events, personnel should refrain from public promotion via social media or other channels, and CDC and other USG staff may attend local events but cannot speak or promote attendance. The memo notes this guidance supersedes previous blanket approval and may require adjustments to planned activities.

Prasad previously announced that he intends to start with the conclusions he wants and work backwards to produce the "evidence."
