- Question: fully vaccinated + catch covid19 == booster dose?
- Can someone be infected with different strains of the same virus at the same time? How would these strains interact?
- COVID mRNA vaccines make proteins which elicit immune system reaction. How does the cell make good (self) proteins from mRNA without the immune system killing them?
- At what temperature is an object considered "too hot" by tactile nerves under the skin, and an "immediately retract the limb!" reflex is issued? Does such sensitivity vary across different skin regions?

- If sonic frequencies above 20khz exists, then is there a way to bring them down to human hearing range?
- Would birth control pills affect the results of a doping test?
- Regarding the vaccine, you are only considered "fully vaccinated" 14 days after your second shot. Does that protection grow exponentially, linearly, or logarithmically?
| Could Enigma code be broken today WITHOUT having access to any enigma machines? Posted: 27 Jul 2021 08:30 AM PDT Obviously computing has come a long way since WWII. Having a captured enigma machine greatly narrows the possible combinations you are searching for and the possible combinations of encoding, even though there are still a lot of possible configurations. A modern computer could probably crack the code in a second, but what if they had no enigma machines at all? Could an intercepted encoded message be cracked today with random replacement of each character with no information about the mechanism of substitution for each character? [link] [comments]  |
| Ask Anything Wednesday - Engineering, Mathematics, Computer Science Posted: 28 Jul 2021 07:00 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]  |
| Question: fully vaccinated + catch covid19 == booster dose? Posted: 27 Jul 2021 05:16 PM PDT Since a few weeks we read about more and more fully vaccinated people catch COVID, often mild cases. I wonder what effect this has on the immune system of the affected people. I am specifically thinking about the group of people who become ill enough to notice symptoms and get tested, but not enough to end up needing treatment in a hospital or ICU. Could the effect in them be similar to a booster shot, or even a variant-specific booster? Has this been studied already, or are there any studies in progress? [link] [comments]  |

| Does the risk of getting Long Covid vary between age groups? Posted: 27 Jul 2021 07:30 PM PDT I'd be interested to know if young people are as likely to get long covid as older adults (35+ years old for example). In addition, are the chances of contracting Long Covid correlated to the severity of symptoms experienced from Covid? Are people with light symptoms as likely to get it as people with severe symptoms? [link] [comments]  |

| Why don't animals have more than 2 eyes. Or eyes in cool places like on the back of their head? Posted: 27 Jul 2021 06:16 AM PDT If animals had eyes on the back of their head wouldn't it increase their vision?and that would be good for herbivorous animals right. [link] [comments]  |
| Can someone have both type 1 and type 2 diabetes? Posted: 27 Jul 2021 05:29 AM PDT |
| Posted: 27 Jul 2021 01:01 PM PDT This might be a dumb question but I'm familiar with frequency shifting and it's fun. Dogs,cats,moths can hear frequencies above 20khz. So it's obvious that they exist. But are there any tools that can do the job. Can we just make it sound in complete silence? [link] [comments]  |
| Would birth control pills affect the results of a doping test? Posted: 27 Jul 2021 09:47 AM PDT With the Olympics happening, it is likely that there are athletes who take or would like to take birth control pills to control the effects of their period or combat related maladies. Would the hormones found in the pills be detectable in a doping test? [link] [comments]  |
| Posted: 27 Jul 2021 07:44 AM PDT I would assume it's logarithmic, but you know what they say about assuming... My question is basically if someone has only had their second shot 7 days ago (half the prescribed period) would they basically be fully vaccinated from a practical point of view? I'm not arguing any public health policies should change, I'm just asking from a personal point of view because I have some acquaintances who are real sticklers about the 2 weeks period. I'm just wondering if they know something I don't, or if I should perhaps discount their overabundance of caution. [link] [comments]  |
