| Posted: 04 May 2022 07:30 AM PDT What do we know about any kind of lasting immunity? Is humanity likely to have to live with Covid forever? If Covid is going to stick around for a long time I guess that means that not only will we have potential to catch a cold and flu but also Covid every year? I tested positive for Covid on Monday so I've been laying in bed wondering about stuff like this. [link] [comments] |

| Ask Anything Wednesday - Engineering, Mathematics, Computer Science Posted: 04 May 2022 07:01 AM PDT Welcome to our weekly feature, Ask Anything Wednesday - this week we are focusing on Engineering, Mathematics, Computer Science 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 does the Collatz Conjecture (and problems like it) matter? Posted: 04 May 2022 09:11 AM PDT I was watching a video from one of the 3628468 youtube channels that the bearded englishman has and it mentioned this problem and I started to think, why does such a thing matter? Seems like just a funny maths thing for a child to play with but in the video the host mentioned that people have "ruined" their careers trying to solve the problem. What would happen if the problem was proved false/true? Is this a check on if maths as a whole work or something? If there is a simple and obvious answer, I do apologize. I'm just a lowly car mechanic and a bass player on top of that. [link] [comments] |

| What was climate and flora and fauna like 90 000 years ago around the ice lakes of Northern Russia? Posted: 04 May 2022 03:22 AM PDT Especially around modern White Sea, Lake Komi and West Siberian Ice Lake as seen in this image that depicts these lakes 90 000 years ago: https://johnhawks.net/images/glacial-lake-west-siberia-mangerud-2004.jpg [link] [comments] |
| Which causes hair loss? Too High or too low testosterone? Posted: 04 May 2022 03:14 AM PDT I often hear that either one or the other causes your hair to fall off. Which is both? [link] [comments] |
| Posted: 03 May 2022 09:41 AM PDT I can't seem to find a whole lot of scientifically tested information on this subject. Assuming a smoothie made only with whole foods (no added sugar or juice - just extra water to aid with blending), my two questions are: a. Does a blender shred the fruit/vegetable fiber too small and significantly reduce how long you "feel full"? b. Would the shredded fiber and juice separated in the blending process cause a significant spike in sugar intake and therefore spike insulin? Ultimately is there a significant difference in having the blender do the work for you instead of chewing? Follow up: Would consuming the smoothie over a long period of time, say over the course of 3-4 hours vs. consuming the whole foods withing one hour have any significant difference?

| How does a simple refracting telescope make more stars visible? Posted: 03 May 2022 02:37 PM PDT My intuition is totally failing me here. If something is invisible to the naked eye, why would magnification make it visible? I can understand how a reflecting telescope that collects a lot of light does this, but it isn't clear to me how a simple arrangement of lens would. [link] [comments] |
| Posted: 04 May 2022 05:07 AM PDT Gravity, as far as I understand, is consistent and uniform so pressure from gravity wouldn't force liquid rock to squirt like a giant zit. Is it the variable nature of gravity's effect from the moon and sun? Localized pressure from tectonic activity or other localized causes? [link] [comments] |
| Are there different (human) brain types? Posted: 04 May 2022 12:21 AM PDT I am aware of the unproven psychological theory of brain types, my question is not about that theory. It is about the factual biological differences and the exsistence of possible types based on the differences. Like there are only a few different hair coulour that differs genetically or a few different blood types, or baldness patterns. Has such differences been researched or discovered in relation to brains? For example something like average dendrite length, or some people has or doesn't have a specific type of neuron?
