| Ask Anything Wednesday - Biology, Chemistry, Neuroscience, Medicine, Psychology Posted: 20 Jan 2021 07:00 AM PST Welcome to our weekly feature, Ask Anything Wednesday - this week we are focusing on Biology, Chemistry, Neuroscience, Medicine, Psychology 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 do vaccines not make the person infectious? Posted: 20 Jan 2021 05:28 AM PST I know a couple of healthcare workers who have now had the Oxford/AstraZeneca vaccine. Each of them has been ill for a couple of days displaying typical flu-like symptoms before returning to full health, which I'm aware is very typical. Why is it that when having the vaccine, which I've read is a weakened version of a different virus make to "look like" Covid-19, that people do display symptoms but aren't actually "ill" and/or contagious?

| How are gem stones categorised? Posted: 19 Jan 2021 07:53 AM PST I'm not entirely sure what science this actually comes under so please correct me if that tag is wrong. I follow a gem stone sub on reddit who often post various gems and more often than not the colour isn't what you'd traditionally expect from the type of stone, e.g. green garnets and pink sapphires. So, given that colour is not a feature that facilitates categorisation, what does? [link] [comments]  |

| What is the approvals process for a vaccine update? Posted: 20 Jan 2021 03:47 AM PST If an update were necessary to the different kinds of covid vaccines, how long would it take before they were approved? [link] [comments]  |
| Do the two dose vaccines require the second dose to be within 2 weeks to be effective? Posted: 19 Jan 2021 07:27 PM PST After reading about Israel's study showing that one dose isn't near as effective as the two, 14-21 days apart, doses that's meant to happen, it got me wondering. Do people who've been vaccinated just need the second dose EVENTUALLY, or does it need to be within that 3 week window to be the stated 90% effectiveness? I understand the concern being that we're handing out 1 dose and letting people wait weeks for the second, leaving them still almost as vulnerable. BUT, will those people finally be protected properly whenever they get the second dose or does effectiveness dwindle dramatically after 3 weeks? [link] [comments]  |
| What percentage of your cells are infected when you're infected with a virus? Posted: 19 Jan 2021 08:01 PM PST One of those weird 2 am geek conversations about the limits of genetic engineering lead to this question. If you have a really bad flu infection, what percentage of your cells would actually have the flu virus active in them? [link] [comments]  |

| Are fast moving 'particles' length-contracted in any way? Posted: 19 Jan 2021 12:46 PM PST I know this is, on some levels, a nonsensical question given that these 'particles' are just field peturbations, but this seems to me like an interesting junction between quantum theory and relativity. Something that is moving at near light speed supposedly sees the universe contracted, and likewise an observer should see this object as contracted in length also. I'm just wondering if this has been confirmed in experiment, say, within colliders; i.e. that fast moving particles appear smaller than when supercooled..? [link] [comments]  |

| Do solar eclipses exhibit Arago spots (aka Poisson/Fresnel spots)? Posted: 19 Jan 2021 04:18 AM PST Arago spots are a phenomenon observed when shining light at a spherical object - one can (surprinsingly) see a bright point at the centre of the shadow. An eclipse seems like a setup that should also generate a Fresnel spot, but I don't remeber there being any talk about bright points in the shadow of an eclipse. [link] [comments]  |
