| How fast does blood flow in a human body? Posted: 31 Dec 2019 09:12 PM PST How fast and how far does blood flow with each pump of the human heart? How much force does the average human heart contract with? How does oxygen get transferred to every cell in the body, is there a capillary leading to every individual cell? And how exactly does blood get through tiny areas in the body, is there some mechanism for even distribution of pressure? (The blood in my pinky toe is so far from the heart, how does it get back?)

| Ask Anything Wednesday - Economics, Political Science, Linguistics, Anthropology Posted: 01 Jan 2020 07:12 AM PST 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]  |

| Posted: 31 Dec 2019 08:58 AM PST Basically, I was wondering if people who eat in huge quantities defecate multiple times per day or if they simply defecate in larger amounts but regular frequency. [link] [comments]  |
| Posted: 31 Dec 2019 10:04 AM PST Checkpoint inhibitors "take the breaks off" the immune system to enable it to attack tumors that express e.g. PD-1. This leads me to wonder how frequently an individual might have somatic mutations that are potentially carcinogenic, but the immune system destroys the mutated cell lines before it ever becomes a clinical issue. Obviously there aren't epidemiological studies detailing the incidence of this, but I'm wondering if my line of thinking above is correct, and if it is, what might be a reasonable estimate if the frequency of this happening over the lifetime of an individual, or incidence across the population as a whole.

| How to make a beaker disappear? Posted: 31 Dec 2019 05:20 PM PST I saw this video on Twitter where a smaller beaker inserted into a larger one gradually becomes invisible as a liquid that looks denser than water is gradually poured into it. The explanation the gave was that the liquid and the beaker had the same refractive index but I believe there's more to it than that. I look forward to having someone shed some light on this.
