| Posted: 08 Feb 2022 06:52 AM PST I've read that about supplements that raise GABA. If you keep using them the receptors get downregulated. However woudnt the same have to happen with other GABA-ertic activities? [link] [comments] |
| Does eye colour affect colour perception? Posted: 07 Feb 2022 06:56 AM PST Do e.g. green-eyed people perceive colours differently than e.g. brown-eyed people? I'm aware of the individual colour perception, but is it related to eye colour? [link] [comments] |

| Are the Pyramids of Giza actually perfect? Posted: 08 Feb 2022 01:21 AM PST Hi Reddit fam Question… The Pyramids of Giza are almost perfectly aligned along the cardinal points. Given that we don't know much about how they came to be; it got me thinking… Is there a possibility that the pyramids were perfectly aligned according to the cardinal points, thousands of years ago, but the earth may be moving? Yes I know the land masses have changed and moved greatly over the years, but will that have an effect astronomically speaking in regards to cardinal points? If not, why not? Please can someone explain this to me? I am no scientist 😅🙏 [link] [comments] |

| Why do sponges only get soft when soaked with water, but not with oil or pure alcohol? Posted: 07 Feb 2022 06:24 PM PST A dry synthetic sponge appears to soak up all three of these liquids - water, mineral oil, and pure isopropyl alcohol. But only liquid water will make it turn soft and easily compressible. Being liquid alone apparently isn't enough to soften a sponge, even though the sponge seems equally able to "hold" any liquid (not hydrophobic/oleophobic/etc) I think even water steam (when aimed at a hot sponge, so as to prevent condensation) fails to make the sponge soft. Why is water special in this regard? [link] [comments] |

| How do subways run on a SINGLE line of wire? Every electrical outlet has two poles. Posted: 07 Feb 2022 06:42 PM PST Subways (or any electrified train for that matter) use overhead wires or third rails. Why are the overhead wires always a single wire? Why isn't there a "fourth rail"? [link] [comments] |
| What are the largest pathogens that the immune system can effectively fight? Posted: 07 Feb 2022 05:25 PM PST We know the immune system can fight viruses and bacteria, but can it fight things that are much larger? Can the immune system be effective against anything visible to the naked eye? [link] [comments] |

| what magnets were used in 19th century electromagnetic experiments? (i.e. Faraday's motor) Posted: 07 Feb 2022 02:36 PM PST what is the 'permanent bar magnet' that was used in Faraday's experiment? A lodestone or a metal rod that had been magnetised? how was it made? [link] [comments] |
| Weight of impact at terminal velocity? Posted: 07 Feb 2022 04:14 PM PST So, let's say you are falling off a skyscraper, and down below is an analog scale. As you reach terminal velocity and make impact with the scale, how much heavier would it read in comparison to your actual weight? For instance, if I jump on a scale, it will momentarily read a very high number due to the force of my body coming down. What would that ratio be at terminal velocity? (I'm about 135lbs if you want to use that number lol) [link] [comments] |
| How does a clinical lab identify what bacteria you’re infected with? Posted: 07 Feb 2022 10:43 AM PST I've been curious about this and not been able to find a clear answer on the Google Machine. For example, say I went into the hospital and they sent a sample out for testing, how does the microbiology lab determine what kind of bacteria it is? Is it just a visual detection under a microscope? Also, when they test what antibiotics would work on the infection, is it an all-in-one identification test/device used, or are there separate tests for identifying the type of bacteria and what antibiotics would work best?

| Is it possible to form an electrolyte in an organic solution without using water or a surfactant? Posted: 07 Feb 2022 07:23 AM PST That's it, I just want to know if it's possible and in case it is, how and with what? Thanks [link] [comments] |
| How much alcohol dehydrogenase is there in the liver? Posted: 07 Feb 2022 05:49 PM PST What is the mass of the alcohol dehydrogenase in the liver when drinking to break down alcohol at the standard rate of .015g/100mL per hour? [link] [comments] |

| Where does the energy of GRB come from? (and a few more questions) Posted: 07 Feb 2022 07:40 PM PST A few questions I cannot really find the answer to. It is theorised that neutron stars are formed when gravity compresses iron and other heavy atoms to the point where protons and electrons fuse together to form neutrons. As I understand, this is would be due to the electron capture process mediated by the W bosons. Which is the same process as the decay of free neutrons into protons, just in reverse. Is this because of the T symmetry of the weak force? As for Gamma ray bursts Do we know the actual mechanism of how they form? I mean, something more profound than the formation of a blackhole due to the collapse of a star or merge/collision. Where does the released energy actually come from? Is it due to the fusion of whatever is inside a neutron star to whatever is inside of a black hole and/or particles disintegrating into pure energy/photons? Secondly, why does it come out of the poles? Is it because of the star's magnetic field? But given that photons are neutrally charged, why would the magnetic field matter? Thirdly, say you have a neutron star just on the edge of it's upper mass limit and a small comet crashes into to, taking it over the edge and making it collapse. Given the extraordinary amount of energy released by the GRB, would this mean that the mass of the resulting blackhole be lower than the one of the neutron star + comet? Thanks! [link] [comments] |
