Northern California’s first condor egg in 100 years reported in redwood tree

Northern California’s first condor egg in 100 years reported in redwood tree

Who COULDN’T use some good news? ‘ Scientists with the Yurok Tribe say that two of dozens of condors released to the wild in Humboldt County since 2022, to reestablish the endangered birds, have paired up, built a nest in a redwood tree and appear to be tending to an egg.”

Finally, today's offering! www.biorxiv.org/content/10.6...

This began life as a very different project which failed because we couldn't agree on defining eqtl sharing across cohorts. So two young members of the lab dug deeply into this - first @ijbeasley.bsky.social, then @patrickgibbs.bsky.social

The real problem is that we publish many more papers per scientist than before.

A two-column status table titled "Stage" and "Start Date" tracks the timeline of a manuscript submission from its preliminary data submission on October 8, 2025, to its eventual withdrawal on March 2, 2026. The log reveals a lengthy and repetitive administrative process, particularly between October 26, 2025, and February 19, 2026, where the status cycled more than ten times between "Contacting Potential Reviewers" and "Waiting for Reviewer Assignment," suggesting significant difficulty in securing peer reviewers. Following these numerous failed attempts to move into the active review phase, the final entry shows the manuscript was officially withdrawn on March 2, 2026, at 09:08:18.

My first paper had to be mailed to Stockholm, Sweden, and then mailed to reviewers around the world. Everything by mail! It was submitted, reviewed, revised, typeset, and published in 3 months. I feel bad for early-career scientists who can't find a single reviewer after 5 months. It's gotta change.

Pangenomes, really?

Most early “pangenomes” = oligogenomes (oligo, Gr., few).

More recent “pangenomes” generally = poligenomes (polis, Gr., many).

True pangenomes (pas, Gr., every/all) would be rare indeed.

🙏🏼 @zbao.bsky.social for pointing out his review.

we talk about carcinization, but never about the many, many times plants have invented the “tree.”

Tree is not a kind of plant, it is a thing plats do, and they are by and large unrelated.

Have you ever wondered 🤔... Does phenotypic variance respond to environmental perturbation? Does it have a genetic basis? Are mean and variance regulating loci exposed to different selection pressures? These and more questions are explored in our new preprint 🔥

Happy Birthday!

I first read about the LTEE in high school in a science magazine my Bio teacher had in the classroom. I don't think I thought "I want to be a microbiologist," but the article planted the seed.

Amazing that it's nearly at "mid life" (by human standards)., excited for what's next!

Written English has barely changed in 300 years. If you can read Harry Potter, you can read Robinson Crusoe (1719).

How far back in time can you understand English? An experiment in language change

If you liked this experiment, I published a full piece today in the same vein: a text that gets 100 years older with every section, from a modern blog post to a medieval chronicle.

It's a single story spanning 1000 years of English. See how far you get.

More good news on vaccines

A two-in-one mRNA vaccine developed by Moderna targets seasonal influenza & COVID-19. It produced robust and durable immune responses w/o safety concerns in a small mid-stage trial.

mRNA is the future. We can’t afford to lose it.

One vaccine may provide broad protection against many respiratory infections and allergens Stanford Medicine researchers and their colleagues invented a new vaccine that protects mice from respiratory viruses, bacteria and allergens — the closest yet to a universal vaccine.

Exciting! Stanford researchers have developed a UNIVERSAL INTRANASAL vaccine. A study in mouse models shows that vaccinated mice were protected against Covid & other coronaviruses. Still a long way to humans. This study was #NIH funded.

A potential game changer.

Now, I have thoughts on all this but that’s for elsewhere. What immediately strikes me most is that Dawkins was using a definition of “gene” that he admits (and Stent acknowledges) was taken from George Williams, and which was common in evolutionary biology then and still is now. But…. /9

A Shapiro-Wilk test of the response variable concludes very significant deviation of Normality. But residuals of linear model consistent with Normal distribution.

Periodic reminder that we should avoid testing the Normality of the response variable.

For a linear model, what matters is the Normality of residuals (and not that much). Visual checks better than test. #statistics

Every politician considering slowing down climate solutions, like the renewables, electric vehicle or heat pump rollout, needs to be fully informed what is at stake and what risks they are taking.
It is often compared to a ship sailing into uncharted waters with dangerous rocks below the surface.
