    Sucks to be her:

    https://www.realclearscience.com/articles/2022/11/07/never-before-seen_mutation_turns_woman_into_a_tumor_factory_863344.html

    A small correction. Article mentions nuclei in 'blood cells'. Most of those are red blood cells, which have no nuclei and are about 1/4 of your total human cell count. But lacking nuclei one could claim they are not cells at all? Just good oxygen haulers. Blood cells with nuclei are of the immune system, and not nearly as many billions.

    ==
    OT and not 'environmental' either ;)

    Red blood cells are not spheres, as spheres have little surface area, which is what hauler-transporters need. They are cute little lozenges

    They must have little strings inside to keep their dimples. Otherwise would revert to spherical, right? Lowest-energy state?

    Hungry hungry Homer. OK then, the shape fries faster, and might carry more dip substance.

    Last I studied up on it - the red cell configuration is held to be perfectly shaped for maximum oxygen absorption. Isn't evolution wonderful?

    It's been around for >400 million years but there is some news:
    Quanta Magazine

    Fun to read especially (for me) the proposed similarity for fungal degradation of lignin.

    If you accept Li's annual pollen production estimate, it can be taken further. In a million years, without decomposition, it would have deposited 400 meters thick on land. Would notice that!

    And a couple of things not discussed. As many allergy sufferers know, there must be something on the surface of pollen grains besides this nearly indestructible sporopollenin molecule. And unique to plant species because you are allergic to one or few.

    When pollen lands on a lady flower, a nearly indestructible pollen grain must open up to 'let the DNA out' so next gen of plants arise. As they do. So, is there an enzyme for that?

    Time for me to email Dr. Li :)

    it is estimated that over one hundred billion human beings have occupied the planet

    Yes, and they decompose rapidly. See Paris catacombs for some exceptions.

    And petroleum.

    Ramifications are for a fossil fuel, with a well invested and expanded infrastructure, getting the same considerations as less developed, renewable sources. It's cleaner than coal, and will have big part in transition to renewable fuels. It doesn't need government help, beyond what it already gets, to do so.

    Received an email from Domino's Pizza detailing their new EV Fleet and 2023 plans. Indiana must be their trial state as their EV distribution and future plans seem to be way ahead of the rest of the nation. Their electric vehicle of choice is the Chevy EV Bolt.

    Here is the link just click on a state to see their current distribution and 2023 plans - looks like they are just getting started

    Note: you have to scroll down a little to the interactive map of the US then click on the states - Indiana is far ahead of the rest of us.
