  • There's a bunch of them, but one more common example is Androgen Insensitivity Syndrome.

    It's also possible to have a non-functional SRY (XY but female), or to be XX with an SRY translocation (XX but male).

    Biology is complicated: pretty much anyone who says it only happens one way or is really simple is wrong.

  • This is a bit misleading. You only need to treat the first generation of 2n watermelon with colchicine (which inhibits the movement of chromosomes during metaphase) to produce a 4n watermelon. Once you have a 4n watermelon, subsequent generations do not require colchicine treatment.

  • There's likely some cases of convergent evolution, but I'm not sure this is settled for all trees.

    I'd suspect that at least some trees with last common ancestors that are shrubs have re-enabled genes that enable the tree phenotype rather than independently evolving the tree phenotype.

    But still really cool (and maybe turns on exactly how much evolution your consider needs to happen before it's convergent evolution.)

  • Because they temporarily block the onset of puberty, not permanently block it. Any effects are mostly reversible if the individual desires. What isn't reversible are the all too frequent side effects of untreated dysphoria: death.

  • Ain't nobody in the US got a fancy kitchen scale.

    Lots of us have them. (Well, basic scales which weigh a tenth of a gram.) They're useful when weighing compressible dry ingredients like flour and brown sugar, and viscous wet ingredients like molasses and corn syrup. They're also helpful when you're multiplying a recipe by a factor that doesn't result in useful units; it's annoying to figure out how to measure out fractional cups that involve teaspoons.

    They also help with portion control if you're watching calories.

  • Not consenting to a police search doesn't stop the search, and that's ok.

    What it does is make the fruits of that search inadmissable, and may also enable you to sue them if the search was unreasonable or excessive, or the pretext violated your rights.

    Even if you know you don't have anything in your car, verbally and clearly say that you don't consent to the search, and would like them to note that fact, but otherwise comply. Lots of people have been caught up by police planting evidence, and you don't want to be one of them.

  • Depends heavily on the kind (and intensity) of radiation. Beta (electron/positron) and gamma (photon) generally won't, but neutron and alpha can. Many of the atoms that become radioactive will rapidly decay, and that's one of the mechanisms behind the impact to structural integrity.

  • Figuring out the Parkinson's linkage is challenging too, because glyphosate is just one of many chemicals used in agricultural settings. It wouldn't be surprising for the correlation to be caused by another chemical with strong evidence of casual linkage to Parkinson's that itself is correlated with glyphosate, like Parquat. (Since Parquat is a herbicide, places that used it may also use (or have switched to) glyphosate.) Totally worth continued scientific study.

  • Exactly.

    The general approach is to use interpretable models where you can understand how the model works and what features it uses to discriminate, but that doesn't work for all ML approaches (and even when it does our understanding is incomplete.)

  • Maybe not the hardest, but still challenging. Unknown biases in training data are a challenge in any experimental design. Opaque ML frequently makes them more challenging to discover.
