    Remember my biochem professor showed that chart at the end of “Biochem 100” We had focused in citric acid cycle, the electron transfer in the mitocondria, basic genetics (amino acids, RNA, DNA), neogluconesis, and something about removing nitrogen from cells +a whole lot more I can’t remember 20 years after the class.

    I ended up doing physical chemistry doing my master thesis on thermodynamics in enzymes. Only a couple of formulas and four laws that is already well defined. Way easier than this

    There was this docureality about seal hunters in the Arctic on Norwegian television a few years back. One of the crew contracted “Spekkfinger” and they had to travel a day to Iceland to drop him off. Apparently there still is a demand somewhere for greenland seal as there was a few boats that the show followed. And they had a crew with cook and all.

    Scientific American points to an important fact.

    "With our latest surveys, such as the Dark Energy Spectroscopic Instrument (DESI) and Euclid, by my very rough estimation, we’ve taken pictures of somewhere around 100 million galaxies out of the two trillion or so estimated to exist in the entire observable universe.

    Shamir’s paradigm-shattering conclusion relies on 263 of them."

    They are discussing bias in the selection.

    “Unfortunately, this kind of extreme selection introduces many opportunities for bias to creep in. When we test a new idea in cosmology—indeed, in all of science—we work to make our conclusion as robust as possible. For example, if we were to change any of these filtering steps, from the selection of survey region to the threshold for deciding whether to include a galaxy in the analysis, our results should hold up or at least show a clear trend where the signal becomes stronger. But there isn’t enough information about such methodological checks in Shamir’s paper to make that judgment, which casts doubt on the validity of the conclusions.”
