| Posted: 16 Jun 2021 07:21 AM PDT I was reading a thread about blood donation and I read that people born in the UK during the Mad Cow Disease spread are still not allowed to donate blood today. How does Mad Cow Disease stay dormant for that long without visible negative effects? Why can't we just test for the individuals who might have it? How have we not eliminated it yet?

| How deep can water be before the water at the bottom starts to phase change from liquid to solid? Posted: 15 Jun 2021 09:24 AM PDT Let's assume the water is pure H20 (and not seawater). How deep could this body of water be before the water pressure is great enough to phase change? What would the water look like at that depth? What type of ice would form? Would average seawater change this answer? [link] [comments]  |
| What happens to a person dying of thirst if they drink seawater? Posted: 16 Jun 2021 05:16 AM PDT If a person is dying of thirst on a raft adrift in the sea, they'll likely be tempted to drink seawater even though they know it won't help. What will happen to the person once they consume some seawater? I know they will eventually die, but I'm curious as to how. Specifically, what happens biologically and psychologically? Biologically: What happens to the body. Psychologically: Do they still feel thirsty? Do they feel any pain? [link] [comments]  |
| Ask Anything Wednesday - Economics, Political Science, Linguistics, Anthropology Posted: 16 Jun 2021 07:00 AM PDT Welcome to our weekly feature, Ask Anything Wednesday - this week we are focusing on Economics, Political Science, Linguistics, Anthropology Do you have a question within these topics you weren't sure was worth submitting? Is something a bit too speculative for a typical /r/AskScience post? No question is too big or small for AAW. In this thread you can ask any science-related question! Things like: "What would happen if...", "How will the future...", "If all the rules for 'X' were different...", "Why does my...". Asking Questions: Please post your question as a top-level response to this, and our team of panellists will be here to answer and discuss your questions. The other topic areas will appear in future Ask Anything Wednesdays, so if you have other questions not covered by this weeks theme please either hold on to it until those topics come around, or go and post over in our sister subreddit /r/AskScienceDiscussion , where every day is Ask Anything Wednesday! Off-theme questions in this post will be removed to try and keep the thread a manageable size for both our readers and panellists. Answering Questions: Please only answer a posted question if you are an expert in the field. The full guidelines for posting responses in AskScience can be found here. In short, this is a moderated subreddit, and responses which do not meet our quality guidelines will be removed. Remember, peer reviewed sources are always appreciated, and anecdotes are absolutely not appropriate. In general if your answer begins with 'I think', or 'I've heard', then it's not suitable for /r/AskScience. If you would like to become a member of the AskScience panel, please refer to the information provided here. Past AskAnythingWednesday posts can be found here. Ask away! [link] [comments]  |
| Why are liquids almost always shiny/reflective? Posted: 15 Jun 2021 10:41 AM PDT I am painting some furniture and just started wondering why almost anything that is in liquid form has a shine? Even flat finish paint is shiny until it dries. Paint, icing, foundation, etc all has shine when wet. And then some materials are still shiny even when dry/solid. Why? I assume it has to do with the motion/arrangement of particles in liquid vs solid states? Is there any liquid that is not reflective? [link] [comments]  |
| Posted: 16 Jun 2021 12:27 AM PDT Many jurisdictions public health agencies released apps that scanned for local Bluetooth devices and in theory told you if you had been near someone who was infected. So did it actually work? Or was a feel good app? [link] [comments]  |
| Can we replicate the process of making fossil fuels? Posted: 15 Jun 2021 08:52 PM PDT Had a question asked by a fourth grader that got me thinking. I'm not concerned if it's viable, economical, or practical. But theoretically could we replicate conditions over a period of time to create crude oil? What would be the rough requirements and timeframe to make this happen? [link] [comments]  |
| If we found a way to reverse a hashing function, would that make them ultra-compression algorithms? Posted: 15 Jun 2021 08:31 AM PDT Given that in principle, a hashing function is meant to produce a unique output for any input, would that mean if you could reverse the hash, you could reconstruct a huge input?

| Posted: 15 Jun 2021 12:59 PM PDT From what I understand, gravity causes things to clump together, which also leads to an increase in entropy. These clumpy formations have higher entropy than a equal distribution of gas particles in a given space. Why is thermal equilibrium, where entropy is maximized, empty space? Is my understanding of what thermal equilibrium actually is wrong? [link] [comments]  |
| When we fart, do we also expel our gut/colon bacteria besides gas? Posted: 15 Jun 2021 10:06 AM PDT |
| HOW do sunflowers face the sun? Posted: 15 Jun 2021 04:49 AM PDT I'm not asking why, I'm asking how. It has puzzled me because they are the only flowers that do this behaviors. No other plants do this, so I'm wondering how it works. [link] [comments]  |
| How many individuals survived the extinction of the dinosaurs? Posted: 15 Jun 2021 10:29 AM PDT I have read in many places that 75% of all species were wiped out in the K-Pg extinction, but do we know what percentage of all individuals died? I imagine for the extinct species this number was close to 100%, but what about the surviving species? Are the survivors concentrated in certain areas of the world, or in certain ecosystems?

| How do we study the chemistry of specific parts of a cell? Posted: 15 Jun 2021 02:02 PM PDT How can a person study the chemical composition of the Golgi Complex or a mitochondria, for example? With a minuscule surgical knife? [link] [comments]  |
