Interesting Blog Posts

One side benefit of the fracturing of society into thousands of weird subcultures is that there are more opportunities for prestige than ever.

Media, Schmedia

Are farmers still using antibiotics to increase animal weight, despite the FDA banning it last year?

While I still recommend you sit as little as possible, being fit makes it less bad.

Everything Else

Medieval peasants took more vacation than the average American.

Weight loss is 80% diet, 10% sleep, 5% exercise, and 5% whether or not you wear shoes inside your house.

I still hold out hope for Nessie.

Changing weather patterns has California farmers placing uncertain bets on the future.

Things I’m Up to and Interested In

Keto breakfasts I’d eat: This guy’s.

Study I found interesting: Another reason not to skip leg day.

Article I’m pondering: Why New Antibiotics Are So Hard to Find.

This is very cool: Yin and yang types have different brain activation patterns in depression, and the fMRI results look incredibly similar to the traditional yin and yang symbol.

Heard in the Roman Empire: “What about barbarian-on-barbarian crime?”

Comment of the Week

I love how you ended this article. So many people hug but don’t really *feel* the hug. My granny would hug very tightly for a very long time, and she always told me I gave the best hugs. Hugging my granny is a great memory I hold dear.

  • I agree. There’s nothing quite like a grandma hug, Tiffany.

    1. All girls throw like girls. I imagine what you’re talking about is the shaming that goes along with the phrase “throws like a girl.”

      1. But the phrase “throws like a girl” appears to be a truth. So if it can’t be said, what respect for the truth and what implications for honest inquiry? Science shouldn’t worry about offending sensibilities.

        1. Technically, the concept behind “throw like a girl” is a residue of a type of top-down categorization of the world that has systematically tormented humanity through the tendency of labelling the world in rigid boxes and bending perception of reality to make it fit your beliefs and work according to your own logical links. Whether it’s semantically right according to your rules tells us nothing about the other organism’s throwing capacities by means of genotypic or phenotypic adaptation. “Girl” means nothing by itself and doesn’t fit even a majority of human females’ experience; rather, it’s an empty template one can easily put together based on their predilections and associate to a living organism and think it’s the same thing. It tells us nothing about reality, so it’s near useless or at least unnecessary in most contexts – – certainly not a “truth” that must command respect. Though science shouldn’t worry about offending sensibilities unless it ventures into the unethical (whatever that may mean), language is still a powerful method of conveying intention and one better understand its inner workings before disseminating unintended effects or misdirection.

    2. Sure, but now you have to carry a copy of that study around with you to show you mean it from a purely scientific perspective.

  1. I wonder if baby-wearing counts as “Weight-bearing exercise” for legs, I am unable to go to the gym anymore as there is no daycare!

    1. Eris, have you happened to read Katy Bowman’s books? She stresses several times that baby and child carrying is EXCELLENT and natural excercise!!! I highly recommend her books if you havent read them already. I wish I’d read them when my kids were much younger. Cheers!

  2. “Are you thinking what I’m thinking, Pinky?”
    “I think so, Brain, but how did they get the mice to do yoga? NARF!”

    1. “I think so Brain, but where did they find the tiny little yoga pants?”

  3. Wasn’t there an issue with validating fMRI imaging within the last 18 months or so that essentially invalidates all studies done under fMRI?

    1. Karen, the problem is that fMRI studies tend to be full of false positives because they’re running so many comparisons to find an effect, that the probability of finding a false positive skyrockets. This was successfully shown nearly a DECADE ago with the dead salmon study. They found that a dead salmon had brain activity when it didn’t of course, but it happens when you run that many comparisons. Shown here https://www.wired.com/2009/09/fmrisalmon/

  4. Different country, but this farmer never has used antibiotics on an animal that wasn’t already sick.

    It’s just not normal in my industry, and incredibly frustrating to hear people carry on as though it is. Same with artificial hormones.

  5. “Scientists” speculating again about history, how often have we seen that?

    It’s bad enough when they speculate about things that we can observe, measure and repeat.

    Inferring motivation when you don’t know who dealt with those skeletons, is just plain silly. It’s far more honest to admit that we Just.. Don’t.. Know..

  6. looking back on that post about thinking you might die . . . reminded me that a post on primal burials/funeral arrangements might be interesting. I know some folks in other states might be limited, but for instance, here in West Virginia we can bury family on our own land, so it opens up a lot of options for simpler, less toxic goodbyes. What do you think?

    1. Fittsdawg, I think this is interesting only conceptually. What if, after burying a family member you wished to sell your property? Are there legal obligations for the new owner? Do you dig up the remains and move them at that point? I have a rental and buried my cremated dog under one of the rose buses there (I intend to return one day). I never mention it, but what if it was a person instead? I think it would be a problem.

  7. As a girl who was the deadliest pitcher on the school softball team, and having an older and young sister equally competent in the sports they chose, I could never understand the other girls we played sport with, who threw a ball like their arms were made of wet spaghetti – no matter how much help or practice they had.

    1. I laughed at this. Good on you for not being a pampered princess.

  8. Is barbarian-on-barbarian violence a surprise? Obviously unreported since they were illiterate but it would have been endemic. How could it not be?

    Even in modern times these things tend to get lost. As late as the 1830s New Zealand Maori were raiding the villages of rival tribes, slaughtering on a huge scale, cooking their victims in earth ovens for feasts, taking baskets of cooked flesh back to their ships, and often taking captives back to their homes to be slaves or maintained for later consumption.

    We tend to hear of the violence between literate and non-literate peoples because they are preserved in the records of the literate. It’s only archaeological evidence that can reveal the deep history of the non-literate.

  9. As stated by Karen below, the fMRI study could probably be a bunch of noisy data and noisy measurements and the theory behind it doesn’t even sound very good! Seems like a lot of data mining to me. The researchers even clearly stated,

    “We did not apply corrections for multiple tests in this Pearson correlation coefficients because the analyses were considered exploratory in nature. ”

    So, many of them probably are false positives.

    The other study with Chess grandmasters and longevity is also problematic because they’re only reporting the Cox hazard proportional models that yielded significant results with their specific adjustment of covariates, but not all the other possible models with several different combinations of covariates.

    It’s simply selective reporting and one way to deal with this is to report all possible models and take the median values from those survival models. Till then, it might be a good idea to be skeptical.

    1. The canola oil is an interesting touch. When the recipe appeared here, it was just nonspecific ‘oil.’ You’ll notice these were the days before avocado oil mayonnaise.
