- Comment on CRISPR used to remove extra chromosomes in Down syndrome and restore cell function 15 hours ago:
TIL
- In the majority of cases, the extra copy of chromosome 21 comes from the mother through the egg.
- In a small percentage (less than 5%) of cases, the extra copy of chromosome 21 comes from the father through the sperm.
- In the remaining cases, the error occurs after fertilization, as the embryo grows.

This is not true on multiple levels. One of the benefits of the Crispr technique is it can be used in vivo, so this sort of treatment will potentially be able to be used at any point in an individual’s life. But also, trisomy-21 isn’t present in sperm or eggs, it’s a mistake in cell division early in fetal development, so applying this technique to an egg would have no purpose or effect.

All this research was done on human cells in vitro. The person you’re responding to was making shit up
- Comment on CRISPR used to remove extra chromosomes in Down syndrome and restore cell function 19 hours ago:
This research was conducted on four human induced pluripotent stem cell lines:
In our previous work, we generated a trisomy 21 iPS cell line derived from skin fibroblasts and three induced disomy iPS cell lines with different combinations of HSA21 (ΔP, ΔM1, and ΔM2) using the chromosome elimination technique
Here’s the previous work
How did you even come to the conclusion mice were involved? Mice aren’t mentioned anywhere

I’m an elder millennial and talk to friends and family on the phone all the time, as does pretty much everyone I know. I’m definitely not speaking for everyone, but I have no doubt the majority of people our age are fine having a phone conversation and are not represented by this meme

You’re welcome to speak for yourself, but you don’t speak for millennials. Most of us don’t mind talking on the phone at all.

Well yes, it does have to have chirality, I just meant it doesn’t have to contain any specific elements.
I’m definitely no expert, but isn’t the D/L notation used in all of chemistry? Sometimes it’s written Δ/Λ, but that’s the same thing. Doesn’t it just describe a molecule’s geometry in a different way from R/S?
- Comment on Enantiomers 1 week ago:
These terms can describe any molecule, btw, doesn’t have to contain carbon

Police departments in general have severe problems, but I encounter police often in my work and can honestly say I’ve never encountered an officer for my city’s dept who’d qualify as morbidly obese
- Comment on Bugs are the tits 1 week ago:
Yes, but you’ll barely feel that. They sting with their stingers, which are so small you typically won’t even feel it at first. If you watch them sting up close, some of them will grab onto you with their mandibles and furiously sting you with their stinger repeatedly. Ants evolved directly from wasps and are basically wingless wasps, which is why they’re such dicks
- Comment on Bugs are the tits 1 week ago:
Same for scorpions, wasps, and ants

This is why releasing sterilized individuals into wild populations seems so promising, it’s species-specific
- Comment on For the little guys. 3 weeks ago:
This isn’t really true though, especially since the mosquitoes in question aren’t even native to the Americas, and whole ecosystems evolved without them. I have also read multiple things about how mosquitoes don’t actually make up much of the diet of these animals anyway, because they are tiny and provide almost no nutrients, these animals prefer most other insects before eating a mosquito

Also not true, the Great Oxidation Event likely knocked out 80% of the species on earth in the paleoproterozoic due to cyanobacteria respiration
- Comment on >:)> 3 weeks ago:
I’m going to guess as an island species, it had no natural predators, and therefore the evolutionary pressure for it to have a wide field of view did not exist

- Comment on Trump to sign executive order he says will slash drug prices by up to 80% 5 weeks ago:
Biden had CMS (The Center for Medicare and Medicaid Services) negotiate some drug prices with pharmaceutical companies on behalf of Medicare recipients. This is entirely legal, because the federal government is the payer for people with Medicare. Pharmaceutical companies want Medicare to keep covering their drugs, so they’re willing to come to the table. Again, this is for Medicare only.
What’s harebrained, blatantly not legal, and unimplementable is, “I hereby order all drug prices in the US to be the lowest in the world!”

And when did Biden and Obama try to unilaterally and unconstitutionally dictate pharmaceutical prices

I don’t think we can say this will be a positive for the middle class because there’s absolutely no actual plan for implementation here
