| Is there any development on higher energy density liquid fuels? Posted: 21 Dec 2021 05:36 AM PST So it seems like the energy density of fossils fuels have more or less completely hit a brickwall. Is there any developments on any new fuel that has higher energy density then the traditional RP1 and jet fuel? [link] [comments] |
| What produces the bad smell in meat that has gone bad? Posted: 20 Dec 2021 07:11 PM PST I have found no answer to this online. When meat goes bad and it starts to smell like sulfur, what is the meat releasing that smells like that? [link] [comments] |
| What is the closest to the alpha-centauri system? Posted: 20 Dec 2021 04:43 PM PST I know that the alpha-centauri system is the closest to the Earth-Sun system, but that doesn't mean we are the closest to it. What is the closest star to alpha-centauri that is not us? [link] [comments] |
| Posted: 21 Dec 2021 05:44 AM PST I know that salicylic acid can help keep your skin clear by breaking down dead skin cells, but why doesn't it break down our hair? Hair is made of keratin and is dead. I was looking into hey salicylic acid shampoo and started to wonder this. The only answers I can find online are a bunch of general information medical pages repeating the same information. I can't find any information out there about the actual mode of action on skin or hair. Really not sure if this is chemistry or human body, but I put it under chemistry because I think it's more about the chemical reaction. [link] [comments] |

| Where on earth have humans been living the longest continually? Posted: 21 Dec 2021 06:25 AM PST Listening to a podcast about ancient Assyria got me thinking: What is the place on earth where humans have been settled the longest continuously? You always hear about the Fertile Crescent being the location of the earliest civilizations, and people still live there, but what about South America or Africa? Are any of the earliest cave dwellings still in use or incorporated into modern settlements? Are there any cities or single sites that have been lived in and built up for, say, 4,000 years? 3,000? Even if the civilization that lived there changed over time. As I type this I'm thinking maybe Jerusalem, but perhaps there are even older places I'm unaware of. [link] [comments] |
| Why does metal taste like it does? Posted: 20 Dec 2021 03:28 PM PST For example blood has this characteristic metallic taste due to the high iron content: in what way are our taste buds stimulated by metal that is so unique as a taste?l [link] [comments] |
| Posted: 20 Dec 2021 03:05 PM PST This may not be the most accurate way to describe it, but I have been told that objects get ripped apart by the roche limit because they get too close to another object and the gravity from the bigger object rips them apart because their mass doesn't have enough gravity to hold itself together. Given we are much smaller and have way less gravity, why don't we get ripped apart in orbit? [link] [comments] |
| how does anti parasitic drugs work? Posted: 20 Dec 2021 04:52 PM PST couldn't find an answer on how the mechanism of antiparasitic drugs work in google. I am quite curious since a lot of anti parasitic plants and drug are involve in cancer treatment alternative. [link] [comments] |

| Is the flu shot tested every year? Posted: 20 Dec 2021 12:53 PM PST I know that every year the strains of flu included in the flu vaccine change. Does this mean that the flu vaccine has to go through new clinical trials every year? If so, how do they select the strains and get it trialed fast enough to roll it out? It seems that would take too long and by the time the vaccine is tested a different strain would be circulating. [link] [comments] |
| How similar does a vaccine have to be to a disease for the vaccine to work? Posted: 21 Dec 2021 06:07 AM PST I have read in a couple different places that the first vaccine was for smallpox. People were deliberately infected with cowpox to prevent smallpox. How can one disease give someone immunity to a completely different disease, and how similar do the diseases have to be for this to work? [link] [comments] |
| Posted: 20 Dec 2021 12:40 PM PST Let me start with, I apologize for my grammar, I've always been one for run on sentences, and terrible writing skills like that Ok, I've had a randomish idea and I would like someone that knows way more than me about these things tell me I'm right or a complete moron, or any combination of the two I have ADHD, medicated with Adderall I have high cholesterol, high enough to have cholesterol deposits by my eyes My levels of vitamin D always come up low, even though I spend 5 days a week outdoors from basically sun up to sun down, take a 2000 unit supplement specifically for vitamin D, and ingest a fair amount of vitamin D fortified milk on a regular basis I also have sexual side effects, that is attributed to the Lexapro but seems pertinent for this either way, to where I can get it up, just not finish and my sex drive is all over the place Ok, given all of that, and how cholesterol is used on the body to make testosterone and estrogen, as well as vitamin D, and (if I was reading that study that I came across that I didn't know the lingo so may actually be completely off) have some Important use in the movement of dopamine in the brain, is it plausible that there is something malfunctioning in the areas that process cholesterol into these things, therefore they aren't working properly, and the cholesterol in my system is free floating because it's not in use?

| Posted: 20 Dec 2021 02:09 PM PST If I remember what I learned in high school biology correctly, when you are infected with a disease your body manufactures antibodies, and after the infection has passed the antibody count starts to decrease but never reaches zero, instead decreasing to some baseline asymptote. Does getting infected again increase that baseline, or is a single infection equivalent to being infected many times? [link] [comments] |
