| Ask Anything Wednesday - Economics, Political Science, Linguistics, Anthropology Posted: 12 Aug 2020 08:09 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]  |

| How does phone charging port moisture detection work? Posted: 12 Aug 2020 02:01 AM PDT I usually play with my phone while in the shower and often the moisture detected notification pops up on my samsung note 8. I looked online but the only results are people trying to get rid of the notification whereas I'm interested in what sort of sensor or system they use to determine that the charging port is indeed moist.

| What does the recent research into T cells and cross immunity of COVID mean? Posted: 12 Aug 2020 06:22 AM PDT I am seeing lots of information regarding this, if you have caught another similar corona virus in the past even if you don't have antibodies you may have T cells or memory cells that may produce a milder case of covid, from my understanding. Would this also be true if you were to later contract a mutated strain of Covid? What are the implications of this, in regards to "immunity" - does this mean that it's possible that once more people get covid that at some point it may become like the common cold?

| Posted: 11 Aug 2020 05:06 PM PDT I'm thinking specifically of this famous photo of the Trinity test, though I know there is a whole series. If it was the first test ever, how did they know in advance how to photograph it without over or under exposing the film? [link] [comments]  |
| Posted: 11 Aug 2020 05:00 PM PDT I made a regular donation again this week, and the screening question about recent vaccinations made me wonder what determines if the vaccine causes a deferral or not. If tens of millions of people suddenly start getting vaccinated all at once to quell a pandemic, I can't imagine it going well for the blood supply if it comes with an automatic several week deferral.

| What would cause an acidic urine pH in a patient with metabolic alkalosis? Posted: 11 Aug 2020 10:41 PM PDT The patient has metabolic alkalosis due to excessive vomiting, yet the pH of the urine is decreasing. Wouldn't the patient be excreting excess HCO3 through the urine making it alkaline? [link] [comments]  |

| Posted: 12 Aug 2020 01:40 AM PDT In response to this study, I am curious about why a bandana would be so much less effective in reducing transmission than a regular cotton mask. The neck gaiter results make sense to me because the material is lighter and meant to be more breathable, but in the case of bandanas, most are made of cotton and then folded over in order to be worn, resulting in two layers of cotton covering a larger area in front of the mouth and nose (at least, in the way that makes most sense to me). Any ideas about this? I'm thinking maybe they aren't folding the bandana, or perhaps the bandana material is not cotton, as they don't define what kind of bandana they use. [link] [comments]  |

| Why do crickets/cicadas make noises? Posted: 11 Aug 2020 10:45 AM PDT Is it some kind of self-defence mechanism, or is it just something that they do? [link] [comments]  |
| How big can a planet physically get? Posted: 10 Aug 2020 11:31 PM PDT In two scenarios what would the maximum size of a planet be, under the best conditions if it's 1. a solid planet such as mars, and 2. a gas giant like Jupiter. [link] [comments]  |
