In the Pixar Cars movies, humans exist but are not depicted or acknowledged since the story is from the perspective of the protagonist vehicles who ignore the organisms inside them, not realizing the profound influence they have on car behavior and society. Humans are the cars' microbiomes.

Three 2025 papers (so far). First: we used transposons to disrupt most genes of the malaria-causing parasite Plasmodium knowlesi, revealing the essential genes for survival, either in general or under antimalarial drugs, providing clues to how parasites can be killed. www.science.org/doi/10.1126/...

These are exquisite bite-sized essays mingling biology facts, nature writing, and personal memoir from the viewpoint of a non-scientist who loves weird organisms, reminiscent of the style of Kathleen Dean Moore.

Happy Darwin Day! Stand up for science!

Get in Dorks, we are going protesting. STAND UP FOR SCIENCE. MARCH 7th 12-4pm. DC AND YOUR STATE CAPITALS. More information to come.

My minister wife is currently preparing a welcome message for tomorrow's church service that will include as many of these banned words as possible: gizmodo.com/the-list-of-...

I like the audacity of this title

What was the single worst day for American science in history? Several days this past week feel like contenders.

The Peter principle says competent workers are promoted until reaching a level of incompetence. The Malthusian growth model says healthy populations expand until reaching a level of starvation. These seem like the same general rule, implying a state of borderline failure is a ubiquitous endpoint.

A great use for a non-human intelligence is training your dog to fetch the newspaper. That's basically what a normal google search does. But new AI tools are like training your dog to read the paper and summarize it for you.

You may not know that one of the single greatest threats to the rainforests of South America right now is the Mennonites. www.maapprogram.org/soy-mennonit... www.maapprogram.org/mennonites-s... www.maapprogram.org/mennonites-d...

@roxannetroup.bsky.social Tomorrow I'm reading your book My Grandpa, My Tree, and Me aloud to an audience. So I need to know, does the narrator pronounce it puh-KAHN or PEE-can? Thanks!

What separates humans from other species? We have been called tool users, rational animals, even featherless bipeds, but none of these descriptors is unique to our kind. It’s time to embrace our one true defining feature: the ability to grow hair longer than one meter in length.

Pondering: I have little confidence that any truly momentous discovery for humanity (like a still-living Neanderthal population in a remote central Asian valley) would be treated in either an ethical or a scientifically rigorous way. Too many competing interested parties (think Kennewick Man). So…

People, there is no salmon DNA in trees. There are salmon atoms in trees, i.e. salmon bodies fertilize trees, which is a cool enough fact in its own. You don’t need to ruin it with a whole 3D model of a DNA molecule. Let’s start 2025 with accurate #scicomm.

What exactly happened here? Four feet off the ground on a fence near a pond, SW Washington. A gravid newt climbed up there, died, and exploded? Why?

We barely survived 45, now here comes 45²

Cervine chronic wasting disease originated in 1846 when Donner the reindeer spent a tragic Christmas trapped in the Sierra Nevada mountains.

Off to see Robin Wall Kimmerer speak!

Facebook’s AI, which has access to decades of my personal and professional information, doesn’t realize that I’m already a scientist. The bots are not ready to take over quite yet.

Today's agenda: 1. Perform Diplotype Clustering. 2. Watch The Diplomat (remember kids, get your diploma and you too can enjoy a diplo-themed lifestyle)

My minister wife occasionally mentions the divine inordinate fondness for beetles in her sermons. Recently a congregant challenged that wasps may outnumber beetles, an idea from bmcecol.biomedcentral.com/articles/10.... popularized in www.amazon.com/Endless-Form... Entomology folks what's your view?

Sci-fi (or real-life?) idea: Cloned mammoths are needed to transform the tundra & retain carbon to prevent climate disaster. Government won’t do it until a scientist invokes Tolkien’s oliphaunts and argues they are ideal battle technology. They aren’t, and hilarious chaos ensues, but Earth is saved.

There's a group of parasites, including hiker's bane Giardia, called the fornicates (Fornicata if you're fancy). As in, "When my buddy goes camping he drinks fornicates and who knows what else". It has a very chaste etymology from Latin for "arch" (soliciting under arches led to the homonym).

In my book I was going to use a particular Richard Dawkins tweet as an example of wrongheaded thinking about eugenics. Then I read Control by @adamrutherford.bsky.social & he addresses the exact same tweet! No problem, since sadly it's not hard to find other examples, but was a surprise to read.

Happy Thanksgiving! I’m thankful I haven’t had a parasitic infection this whole year. My ancestors would have been astonished at my good fortune.

Genetics is not basic science because DNA is an acid

Almost every week I see talk(s) on research funded by NIAID. Few Americans are aware of this institute or really care that it's on the chopping block, ironically because NIAID isn't in the news much as it doesn't inconvenience anyone and only supports science that keeps us all safe from disease.

I know the red/blue political colors are supposed to be arbitrary, but it's really hitting home this month that when Republicans lose they get angry while when Democrats lose they get sad. Hang in there, folks, and don't give in to despair. America, and and world, needs you.

Big news: I'm writing a book! A non-fiction popular science book about (not so) natural selection as it is caused by and (mis)understood by humans. Population genetics tied to society and culture. Read about it here: adaptivediversity.wordpress.com/2024/11/23/p... Now looking for a literary agent.

Any time I read about multipass membrane proteins

Does anyone have experience using Nanopore to quantify the abundance of different haplotypes in PCR amplicon data? Is it accurate? Are there caveats or a need for data filtering?
