    Teaching kids to use guns doesn’t save kids’ lives. If you want to teach em to stay away from guns, that they’re deadly, they shouldn’t touch it and should tell an adult right away go ahead.

    Teaching kids to use guns in the name of gun safety is like saying you need to teach them how to drive in case they find some car keys lying around and decide to take it for a spin.


  • Already in the comment, click the links.

    https://www.safekidsinc.com/hero-program-overview

    Here’s where it goes through their curriculum per grade level including pre schoolers.

    The 'heroes" program is not teaching pre schoolers to use guns, it’s teaching them about active shooter situations.

    The other link was the one offering actual gun training (for 7 year olds and up so second graders potentially).

    My comment was that it’s sad we apparently need programs to to teach pre schoolers about how to deal with active shooting situations now.

    The one I linked specifically mentions shooting afterwards for kids as young as 7…

    But yes if guns are at home they should be locked (and really locked, like a trigger lock plus a safe that’s set to something besides 1111, holy crap you’d be surprised at how cavelier some people are) and totally inaccessible to kids. Teaching single digit age kids about guns is not a substitute for that, but of course I’m not saying you shouldn’t teach your kids that they shouldn’t touch guns and what they can do.

    And teaching kids about guns will not solve the serious gun problems in America. The gun problems unique to America that pretty much every other industrialized nation has figured out already. And it’s a horrible tragedy that stuff like “the heroes program” to teach preschoolers how to deal with active shooters is necessary in this country. All to please gun nuts.

    Most gun nuts aren’t too interested in education anyways:

  • Oh yes absolutely op’s x chromosome is expressed. I just meant unlike all the other chromosomes where in general both gene copies on both chromosomes are expressed, in xx individuals usually one of the x chromomes is inactivated and only one of them is being expressed at a time. The x chromosome has many essential genes. This is why we have x linked genetic diseases as well. Often xx individuals are just carriers or more mildly affected since they have two x chromosomes, and xy individuals are more severely affected since they have no backup copies of that gene.



  • Thank you for clarifying those misconceptions about what recessive and dominant are getting at. A gene isn’t really dominant or recessive. A phenotype (some trait in the organism like blue eyes or a certain disease) can be dominant or recessive though and results from changes in a gene. The same gene could have many different possible mutations, some with dominant effects, some with recessive effects, or some with no effects, depending on the change in the gene and the phenotype.

    To go further on that, many recessive diseases are because just one functional copy of many genes are fine from your body’s perspective. Many recessive diseases are due to loss of function of a gene or its protein product, a gene that for a variety of potential reasons no longer leads to a functional protein. Often your body can get by with just one working gene making protein, though both gene copies are generally always being transcribed and trying to be turned into functional protein.

    One big exception to this is the x chromosome. Males only have one x and have a y instead of a second x. The y is very tiny and has very few genes compared to the x, quite different from other chromosome pairs which generally just have copies of all the same genes on each other. Early in embryo development for xx individuals, one of the x chromosomes is generally inactivated and not expressed very much, otherwise xx individuals would have double the gene products of all those different genes compared to males, which the body is not expecting for x genes like it does for all the other genes that have a second copy.

    https://en.m.wikipedia.org/wiki/X-inactivation

    If you go even further you also get into the idea of penetrance. A gene codes for a protein, but that protein doesn’t exist in isolation, it interacts with lots of other proteins coded by other genes in the body, plus the environment. So for some genetic changes it might be a 100% chance at leading to a certain phenotype (like a disease or a specific trait), or it could be less, like only 70% or 30% chance or something of someone with that change getting that trait, even if it’s still “dominant” (meaning only one gene copy with that change is needed to express the trait).


  • Do they not use the word country as a synonym for rural? I checked the Cambridge dictionary, it’s their second definition listed, even higher than where that definition is listed in Merriam Webster. It’s like complaining rock music is made with guitars instead of boulders. Does he also think that country is like the only genre of music made in America? Though some country singers do like to put a lot of nationalism in their music which does kind of confuse things.

    I’m a firm mayo by itself as a sauce hater though so I’m with him there. Even more abominable are the jello (or jelly for those in the UK) “salads.” It’s not a salad!



  • We’re working with an n of 1 basically. If you’re talking about the drake equation, many of those terms are wild estimates that we simply don’t know the answer to, it’s more of a thought experiment. In the course of astronomy history when we’ve assumed uniqueness about earth or our cosmic situation we’ve generally been wrong. Unfortunately the vast distances between stars make an estimation of life in the universe difficult with current technology, as there is so much we can’t observe.

    But there’s billions of stars in the galaxy, billions more planets, and septillions of star systems in the universe with billions of years for life to happen. Intelligent life has happened at least once because we’re here. Even in the tiny slice of planets we’ve been able to observe in some way in our narrow little corner of the galaxy we’ve found numerous ones in the “goldilocks” zone. It would be utterly shocking if we were the only intelligent life out there, even more shocking if our planet had the only life. And all of this assumes we know what kinds of life are possible! We’ve only ever seen our own type of chemistry.

    Don’t mistake this for me saying we’ve been visited by aliens in UFOs or something though, not saying that at all.
