| Is it true that babies see upside down for a short period of time? Posted: 12 Apr 2022 07:41 AM PDT I Heard this claim multiple time ex.: https://www.reference.com/world-view/babies-see-upside-down-2c7003b02ae612ed I understand that the image is upside down on the Retina but I dont understand how that coressponds to the percievied image. The way I understand it the brain hast to somehow make sense of the Signals coming from the Retina but I dont understand how it would first Form an upside down Image from these Signals and than later flip it. Edit: I guess what I am trying to say is: From the brains Perspective its Just "random" neurons in the optic nerve firing so the orientation of the image should Not matter couse its Not an orderly System in the first place.

| Posted: 12 Apr 2022 10:34 PM PDT In regards to genetic mutations which occur "by chance" or "by mistake" during mitosis and disregarding the effect of carcinogens or environmental factors: How do we know that genetic mutations leading to cancerous cells are "mistakes" during cell division? How do we know that cells aren't purposely trying to mutate certain genes? Could it be possible that each cell of our body actually has its own selfish desire for individuality and wants to escape from the enforced DNA instructions to serve a multicellular body? Could it be possible each cell carries its own desire to survive, causing it to try to break the genes which would lead to forced suicide (apoptosis)? Why is cancer so common at old age? If cell aging increases the likelihood of developing genetic mutations, why is it that the DNA phenotype resulting from these mutations so commonly uncontrolled cell division (cancer)? I understand that the accumulation of mutations over time can increase the likelihood of cancer, but why don't other mutations show harmful effects before the resulting effects uncontrolled cell division once the tumor suppressor genes are mutated? Or could this "mistake" during mitosis resulting in genetic mutation be in line with how existence revolves around creating variation and possibilities to test with natural selection? Rather it be a "mistake", but perhaps further another way to create variation? [link] [comments] |
| How can prion diseases be genetic? Posted: 12 Apr 2022 06:06 PM PDT I have a question regarding genetic prion diseases, FFI as an example. Sorry if this question doesn't make a lot of sense I have no formal scientific education, just interest. So if prions contain no genetic material such as DNA, how can a parent pass down a prion disease? My understanding is each parent gives you a chromosome, chromosomes contain your DNA and your genes, a gene disorder is inherited by a parent. FFI is autosomal so the gene for it is found on a chromosome from the parent, correct? But wouldn't that make no sense if prions have no DNA? How would they be from a chromosome? Again, sorry if this is nonsense lol [link] [comments] |
| Why are so many oil deposits located in dry areas? Posted: 12 Apr 2022 08:55 PM PDT I wondered this while looking at a map of oil deposits, regions like Central Algeria or the American Southwest , are mostly desert or dry areas where life cannot thrive and thus barely any lifeforms are turned into petroleum by natural processes. Also other dry places like Alaska might not be desert but lack a lot of lifeforms. [link] [comments] |
| Do older (non-human) animals lose their ability to hear high-pitched noises? Posted: 12 Apr 2022 06:22 AM PDT I have a computer from the 80s with a built in cathode ray tube (CRT) that makes a very loud, very high-pitched noise. I can't hear the sound (because I'm "old", apparently), but my 11 year old daughter complains when I use the computer. To keep her happy I just don't use it when she is around. However, my question is whether our pet rabbit can hear the noise. According to Google, the human hearing range is 20Hz to 20kHz and the rabbit hearing range is 360Hz to 42kHz. Snuggles the Bunny is almost 13 years old; for all I know, the old man is deaf. Does anyone know how a rabbit's hearing range changes with age? I think I'll just move the computer to a different part of the house anyway, but I was just curious. [link] [comments] |

| How does immunotherapy (allergy shots) work when regular exposure to pollen doesn't? Posted: 12 Apr 2022 09:39 AM PDT I've searched this and every site gives some unhelpful answer about injecting the irritant and building up a tolerance. But we suffer from allergies every year and don't build up a tolerance. Is there something special about the delivery mechanism? The substance delivered? The exact dosage? Could I sniff exactly the right amount of tree on exactly the right schedule and get the same effect? [link] [comments] |

| Is there a place on earth where meteors hit fairly regularly? Posted: 11 Apr 2022 10:47 AM PDT Is there a place on earth where meteors hit fairly regularly? I know we get approximately 17 meteors hitting the earth a day but I want to know if anyone would know if there's a place that they commonly hit. [link] [comments] |
| If the Earth is turning and therefore we’re accelerating, why don’t we feel the Earth’s rotation? Posted: 11 Apr 2022 05:54 AM PDT Not a flat earther or anything If acceleration is a change in velocity, when the Earth is turning we have a change in velocity. Unless I'm wrong, a vector drawing would show us decelerating in a "forward" direction and accelerating in a "sideways" direction. Can someone explain to me why we don't feel this acceleration like we would in a car going around a round-about? [link] [comments] |
| Is there a notable difference in child-bearing between people with and without siblings? Posted: 11 Apr 2022 05:14 AM PDT First of all, hello askscience! Big fan here. I'm trying to research if only children are less likely to have their own children, but struggling to find relevant data. Any insights would be appreciated. [link] [comments] |
| Do markets become more efficient as the number of algorithmic trading increases? Posted: 11 Apr 2022 10:42 AM PDT For example, let's say the efficient market hypothesis is false, so therefore markets are inefficient, and traders make irrational trades. As the number of quantitive algorithmic trading approaches infinity, and human-based trading approaches 0, would markets become perfectly efficient? [link] [comments] |
| HHO (Brown's Gas) combustion question..? Posted: 11 Apr 2022 05:35 AM PDT I have a question about HHO (Brown's gas). I have been watching some interesting videos about electrolysis of water where the gases (2 hydrogena and 1 oxygen) are collected together in the same chamber, forming Brown's gas. This is obviously quite volatile stuff, but it prompts a question... If ignited lots of energy would be released, but, would it expand or contract? Since HHO is just the stuff of water in gaseous form (not combined), wouldn't it combust back into water (liquid, once cool) at a much reduced volume? Ie - would a sealed container of pure HHO collapse or explode when ignited? (I have no intention of attempting this, of course...) [link] [comments] |
