| Do ASPM and Microcephalin genes really predict IQ and behavior? Posted: 24 Feb 2022 08:31 PM PST Hi I was debating an Anglo Saxon racialist on race and IQ and he cited "Linguistic tone is related to the population frequency of the adaptive haplogroups of two brain size genes, ASPM and Microcephalin" and "What about the ASPM gene of chromosome one a new ASPM allele arose in Eurasia and has been suspected at increasing intelligence and has been demonstrated to be absent in blacks." he sent this Linguistic tone is related to the population frequency of the adaptive haplogroups of two brain size genes, ASPM and Microcephalin | PNAS So my question is, is this a misreading or motivated reasoning for hatred? I also want to understand why this is wrong (if it is) and how to dismantle this argument thoroughly? [link] [comments] |
| Where do the spores that cause mold on bread come from? Posted: 24 Feb 2022 12:39 PM PST Are there spores in the bakeries where the bread is baked and they get in/on the bread before it is even packaged? Or are there spores living on my skin that are transferred onto the bread each time I open the bag to get a couple of slices? Or are they just floating around in my kitchen and each time I open the bread bag, some of that spore-bearing air ends up inside of the bag? Will an unopened loaf of bread still get moldy? Also, some related questions: Why do "name brand" breads (eg Wonderbread or Dempster's) seem to last forever without getting moldy (or even stale for that matter) while more "artisanal" breads produced by independent bakeries always go moldy in under a week, and "grocery store" breads produced by in-house bakeries at grocery stores seem to fall somewhere in between, usually getting moldy after 1-2 weeks? Is the difference in shelf-life of these different types of breads due to different preservatives being used, or does it have more to do with the environment in which the breads are made? What is going on between the time a spore is first introduced to a loaf of bread and the point where the mold becomes detectable (either visually or by scent)? Is there ever a point where the mold is not detectable but still dangerous? [link] [comments] |
| What is the difference between TBI and a concussion? Posted: 24 Feb 2022 08:47 PM PST Hi, I don't fully understand the difference between a TBI and a concussion. I understand they're both head traumas, but what exactly is the difference? Can someone help clarify, thanks! [link] [comments] |
| Are there stars that shine too faint to show up in the night sky? Posted: 24 Feb 2022 08:16 PM PST If the square inverse law holds surely at some point we just won't see it. And if this is true, doesn't that explain partially why the night sky isn't lit up with stars? [link] [comments] |
| Do cardiopulmonary baroreceptors increase or decrease SNS? Posted: 24 Feb 2022 08:28 PM PST My understanding is that low pressure cardiopulmonary baroreceptors sense a change in plasma volume (>10%) and decreases firing rate to NTS. This results in decreasing SNS and increasing PNS response and causes decreasing renin, ADH and increasing ANP release - so overall more water loss to return your plasma volume back to baseline. However, it also causes increase heart rate (Bainbridge mechanism) which is mediated by increase SNS? So how does that work (as in does cardiopulmonary pressue receptors increasing SNS or decreasing SNS??) [link] [comments] |
| What happened to the water on Mars after it evaporated off? Posted: 24 Feb 2022 12:01 AM PST So Mars lost most of its water, probably over a long period of time. That's a lot of water. Where is it now? Is it orbiting the sun in a similar orbit? Was it left behind when the solar system moved around the galaxy? Was it pushed somewhere by the solar wind? [link] [comments] |
| why do we drink milk after spicy food? Posted: 24 Feb 2022 05:01 AM PST I used to think milk was alkaline, hence would combat the acids that lead to spiciness, upon learning that milk is mildly acidic I am stumped as to why it calms down spicy sensations? Any help is much appreciated. [link] [comments] |
