  • The part that this headline skips over is that it’s followed by 5 hours of pricing that are 3 times the regular rate, and then the rest of the day is a rare slightly under the old rate. The expensive rate kicks in between 4pm and 9pm, which is pretty much when the solar supply eases off and dries up.

    If you work from home, it’s possible to shift some of the big load equipment to early afternoon, but some, like ovens and heaters aren’t so easy to shift. You really need to do the maths to see if it works.

    If you’ve got a battery, you’re in a better position, because you can use your own solar and/or the free hours to top the battery up, and then draw on it during the expensive hours. Our battery isn’t quite big enough to carry us through 5 hours, but it gets us most of the way there, so the maths made it worth us to change to the new tariff.






  • The Y chromosome doesn’t carry much of anything. It’s basically just a carrier for the SRY gene, and in most cases, it’s that gene that triggers the majority of the sexual differentiation that occurs in early development. The actual “code” for what develops and how it develops is there for male and female differentiation in all humans, and it’s hormones and other factors that control whether or not that genetic code is expressed.

    And in this case, we’re talking about stem cells (ie, a cell that has the potential to develop in to any cell, but hasn’t yet done so), and then artificially triggering those stem cell to develop in to sperm cells. A trick that can be done because the genetic code for it to do so is already there if the conditions are right.

    As an aside, this is also why hormone replacement for trans people lets them develop secondary sexual characteristics that they wouldn’t otherwise develop. The code was already there, it just takes the right trigger to get the code expressing (in this case, hormones)


  • If not exactly identical, would they be like twins?

    The parents? Basically, as the only difference between them is a single chromosome out of the 26 we carry. There are slight genetic differences between identical twins, due to the accrual of mutations during cell division, but it’s smaller than a full different chromosome. That’s splitting hairs though, because both identical twins and our theoretical clones would be functionally identical.

    If not exactly identical, would they be like twins?

    If you mean the parents and their child, then they’d be somewhere between identical twin and regular sibling in terms of genetic similarity. Regular siblings on average, share about 50% DNA. Identical twins share 100% DNA. Our theoretical child in this scenario would share around 75% of their parents DNA






  • As in pushing back and making noise when people post stuff that helps keep her relevant.

    If I have a tool for decreasing the amount of harm she does, this is it.

    Will it make much difference? No, but if a single person hesitates before posting potter stuff in the future, then it helped a little
