An unpleasant memory

I just had a flashback to my worst academic experience ever. I think it was a combination of my recent posts about all those scientists losing their jobs and that cool video of Pakistani mechanics cutting and shaping steel.

In the 1990s, I was an assistant professor at Temple University, and I had a magnificent custom microscopy rig. A top of the line Leica was at the heart of it, but I had modified the heck out of it. I’d built an air table — a massive 2cm thick sheet of steel resting on a cushion of tennis balls — that had been a huge effort to get cut and hauled up to my lab. I had hydraulic actuators for single cell injections. The microscope itself was modified with a motorized stage and a UV filter wheel (thanks to my friends at Applied Scientific Instrumentation, who are still in business, I’m pleased to see) all programmable and controlled by custom software I’d written. It was beautiful, and unique.

Unfortunately, I did not get tenure at Temple. You may not be aware of this, but if you’re hired by a university for a tenure track faculty position, and you do not get tenure, you’re done. You have one year to clear out your stuff, and then the axe falls, and there ain’t nothin’ you can do about it. You’re a dead man walking, still ambling zombie-like about the university, still obligated to do your teaching and committee duties, but there’s a deadline ahead of you, at which time you have to vacate your office, your lab, everything, it all comes to an abrupt close.

Yeesh, but that was a miserable year, with all my former colleagues cutting ties. Fortunately, I landed another job in Minnesota, but that gorgeous microscope was not mine, it belonged to the university. I had to abandon it.

But that wasn’t the worst of it. At that time, there was a political crisis: HMOs were consolidating and going bankrupt, and many of them had associations with research universities that they were abruptly shutting down. Temple saw that they could buy up entire research groups for a song! It was time to shuffle out the peons working at their university already, and instead bring in all these big biomedical people who already had research grants. And so they did.

One day, in the waning days of my employment, a pair of these new hires walked into my lab, zeroed in on my microscope (that I was using at the time!), and started taking photos, writing down part numbers, and measuring stuff with a tape measure, while talking to each other about where they could put it in their lab space. They looked a bit puzzled by the filter wheel and the weird piezoelectric stage and the strange camera I was using, but they didn’t ask about any of it. They didn’t talk to me at all. They didn’t even acknowledge my existence. It was a strange experience that left me feeling like a ghost, and also sad, because these clueless twits were no doubt going to carve up my microscope for parts.

It was a dehumanizing experience that poisoned all my good memories of working at Temple. It did make me feel better about saying goodbye to that place.

Academia is a cruel and heartless beast, and overpaid biomedical researchers who lack the basics of human interaction are the worst.

They aren’t coming back, you know

Conservatives hate science. This is why they slashed budgets to science agencies, and put lunatic ideologues in charge of the NIH, NSF, and the environment, with the clear intent to cut the knees out from under science education and policy. Jessica Knurick is precisely right on this matter.

You can also see it in the staffing of all of these critical science organizations.

It’s like science got pushed off a cliff when Trump took office.

Perhaps you would like me to reassure you that once we throw the rascals out and elect responsible politicians who respect the role science has played in American prosperity, we’ll just hire them back. No, sorry, this isn’t like rehiring workers at the Amazon warehouse. A science hire is accompanied by a large investment in equipment and personnel. I’m at a small liberal arts college; when I was hired here, I was also offered tens of thousands of dollars in startup money to set up my lab the way I needed to be able to do my work. I was dirt cheap. I’ve known colleagues who were offered hundreds of thousands of dollars, and even a few who got somewhere near a million dollars, to cover the ancillary costs of setting up a major lab.

It’s not as if a custom lab and technicians and instruments are sitting around waiting for someone with the expertise to do cutting edge research to show up. This stuff needs to be assembled at great cost to fill a need.

The people are also not generic tools you can swap in and out. We pay science staff peanuts for years, and we hang in there to do the work we love — we generally don’t have a massive financial cushion to weather heavy shifts in employment. Some of those laid off personnel are going to leave the country, looking for work in a nation that doesn’t disrespect science, while most are going to simply give up, get a job at that Amazon warehouse or switch to writing software. Their hearts are broken by the American science establishment. They’re not going to revisit this occupation shown to be willing to discard them if an orange moron gets elected or a con man with half his brain eaten by worms gets appointed.

That is a graph of disillusionment. It would take decades and a new generation to repair it, if we even had the will to bring science back. Given that the damage is being delivered right down to support for grade school education, don’t even count on a single generation being enough.

It’s not just a few people being let go. It’s the demolition of a cultural heritage of science.

Why is genetics hard?

First day back in the classroom, teaching genetics, and I speculate for a bit about why so many people find the subject difficult. I’ve had smart students who struggled with the concepts. I think the answer is that many people don’t get the whole idea of chance and probability and the statistical nature of inheritance.

The autofocus on my camera was a bit goofy. Someday I’ll get this all figured out.

Speaking of disease…

Another little change in national health policy has occurred.

States will no longer be required to report how many children they vaccinate to the Centers for Medicare and Medicaid Services (CMS), according to a December 30 letter to state health officials.

Maybe if we pretend that infectious disease no longer exists, it will stop happening. Crawl under your bed, close your eyes, and the horrible monster will disappear.

This is just the first phase, though. Over a year ago, Florida was pioneering the way forward.

As Florida moves to become the first in the United States to drop all childhood vaccine requirements, critics have warned of the plan’s potentially deadly public health consequences.

The move would scrap all required vaccine mandates for children, including those required for school attendance, such as polio, diphtheria, rubeola, rubella, pertussis, mumps and tetanus.

The state’s Surgeon General Joseph Ladapo, a longtime vaccine skeptic, on Wednesday compared school vaccine mandates to slavery, calling them “immoral” intrusions on parents’ rights.

“Who am I to tell you what your child should put in their body? I don’t have that right. Your body is a gift from God,” he said.

Children won’t be dying, if we stop reporting on it. Brilliant.

On a related note, I just saw this comment from Gwen Pearson that fits perfectly.

If you have ever dealt with lice, you know that they’re terribly difficult to get rid of, especially if one of the kids’ playmates is constantly recontaminating your family with the problem — if it’s happening at school, everyone in the classroom must take steps to eradicate the nits and lice. It’s the same story with measles, or whooping cough, or polio. Awareness is key, and our government wants to blind us.

Let’s talk on Saturday

I’m a terrible YouTuber — uncharismatic, dull, lacking in visual skills, and incapable of maintaining a consistent schedule — but heck, I’ll try again. Tomorrow (Saturday, 20 December), I’ll go live around 3pm Central time. I’m open to talking about just about anything, but will center the discussion on this paper:

Christopher J. Kay, Anja Spang, Gergely J. Szöllősi, Davide Pisani, Tom A. Williams & Philip C. J. Donoghue (2025) Dated gene duplications elucidate the evolutionary assembly of eukaryotes. Nature, 3 December 2025, DOI: 10.1038/s41586-025-09808-z.

If you don’t want to read an 11 page technical paper, just contemplate this figure:

Or you can just tune in and maybe I’ll explain it.

DDT causes polio???!?

I think I’m trapped at home today — I tried walking to work, and didn’t get beyond my driveway, because we had a thaw and a refreeze and it’s slick as snot out there. Then we’re supposed to get more snow this morning, with temperatures plummeting down to -15°C with 50mph wind gusts, so I’m cowering at home today. The spiders will go hungry for a day (they are opportunistic feeders, they can handle it).

If you’re similarly stuck at home, here’s an hour long video that I thought was very good. It rips into a couple of self-styled “science” based influencers who are anything but.

The most shocking bit was seeing Joe Rogan getting furious at any push-back on his anti-vax views, and basically shutting down the conversation by claiming that the polio epidemic was co-incident with they years of heaviest DDT use. He also made the standard skeptical claim that vaccines were a late response to an already fading plague, which is sort of true. There are multiple approaches to a serious disease: behavioral shifts, like self-quarantine, and improved hygiene can reduce the incidence and severity of infections, but it takes efficacious medical responses to deliver the coup de grace. And Joe Rogan doesn’t understand science at all if he falls for the correlation equals causation canard. DDT does not cause polio.

The video also jumps on Bill Maher. He’s got this canned response to any claims, saying that we don’t know 100% of everything, more like 20% or 10%, so his weird fads might be true. It’s nonsense. Of course there is much left to learn, but we can say with 100% confidence that you shouldn’t eat cyanide, or that the earth is spherical, or that vaccines don’t cause autism, because smart, skeptical people have studied that stuff and have objective data to back up their arguments. We don’t even quantify knowledge as a percentage fraction of everything, so that’s a bogus metric anyway. I’m willing to go along with a claim that we only know 0.00001% of everything, but that the bits we know, we know pretty damn well, so please, Bill Maher, don’t jump off the roof of a New York skyscraper to test your ‘theory’ of gravity.

Another good topic was about what having a PhD means. It’s not a free pass to make everything you say valuable, important, and true. It just says you passed an apprenticeship. You presumably got some training in critical thinking which the Joe Rogans of the world lack, but you have to demonstrate your skills throughout your life. There are also some really bad theses out there — there is some pressure to get students out the door so you can get a new crop started, and some bad PIs who will let garbage pass as long as they get a publication out of it.

(By the way, I think my PhD thesis holds up. Not only did multiple researchers build on it afterwards, but it wasn’t even just mine — it was the product of a collaboration with several absolutely brilliant mentors and colleagues, which is how every thesis ought to be.)

You need some more spider information

We just struggled to figure out how to put fitted sheets on a split-top bed, so I’m too tired to do it. Here are a few videos to do the job.

This first one is looking at spiders from an evolutionary perspective — it’s at a basic level, since the first thing it has to explain is that spiders aren’t insects.

This second one is more about spider cognition. It has a similar problem, since what it says isn’t really new. I took a grad-level physiology course from Michael Land in 1980 that focused almost entirely on jumping spiders, and we talked about similar things.

That course was the highlight of my first year of grad school. I guess it’s not surprising that I returned to spiders here in my dotage.
