| Can you have concussive force in space? Posted: 29 Jan 2020 01:18 AM PST For example, if an explosion takes place say 20 meters from me on Earth that would cause massive internal trauma due to concussive force, will the effect be the same in the vaccuum of space? Not counting heat/shrapnel of course. [link] [comments]  |
| Ask Anything Wednesday - Economics, Political Science, Linguistics, Anthropology Posted: 29 Jan 2020 07:08 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]  |
| For Gram stains does the order you add safranin and methyl violet matter, and if so why ? Posted: 29 Jan 2020 05:05 AM PST If you add safranin first and continue the steps for a gram stain would it still not work as the ethanol will remove the purple stain from G- revealing the safranin which it was stained by earlier.

| How do mobile telescopes such as Hubble and SOFIA track their target whilst they're in motion? Posted: 29 Jan 2020 01:54 AM PST Hubble is orbiting around the Earth at huge speed, SOFIA moves at the speed of a plane - how do they accurately track their target whilst in motion? I'm an amateur astrophotographer and I have to polar align before each imaging session, with even miniscule movements of the mount completely ruining subs - so how do these mobile telescopes do it at speed?

| Do monocots, dicots, C3, C4 or water plants all have the same ratio of photosynthesis? Posted: 28 Jan 2020 06:58 PM PST Edit: For some reason I can NOT see the comments, but I can receive notifications. If I'm not mistaken, one of the comments below asks to elaborate on ratio. This question was asked after the Leaf-Disk Experiment for my biology class. I'm trying to figure out if all the plants mentioned in the question above have the same respiration ratio when it comes to absorbing CO2 and emitting oxygen. [link] [comments]  |

| how did the spanish flu suddently die? Posted: 28 Jan 2020 10:55 PM PST the worst pandemic in human history, present in all corners of the planet and it just lasted 1 year, out of nowhere the virus died at pretty much the same time in the whole world. I know the immune system with time can find a way to protect againts a new virus BUT is not like all humans immune systems are connected to each other and they all at the same time found way to kill the virus. Also, you need to first be infected for your immune system to developpe an antidote, so shouldnt the spanish flu keep on going until the next generation where those who were infected passed down their immunity to their children? Ok last question, how do scientist keep the virus stored? if it died out of nowhere how come they kept the virus alive in the lab? [link] [comments]  |
| If there are places below Sea Levels why aren’t they flooded? Posted: 28 Jan 2020 08:15 PM PST This is a new concept to me so if I'm Sounding dumb I'm sorry I'm new but I was wondering why? Also please simplify your answers I'm stupid. [link] [comments]  |

| To what extent (if any) does psychopathy appear to be genetic? Posted: 28 Jan 2020 09:24 PM PST I realize that there are a number of factors that play into psychopathy, but I've been wondering for a while how much influence genes have on it. While it is something that is difficult to actually run an experiment on (for obvious reasons), I would assume that someone has done data analysis to at least start to address this question, but I'm not familiar with it.

| Posted: 28 Jan 2020 07:32 PM PST Say a 4000 lb car produces 200 lbft of torque for a given RPM and a 3000 lb car produces 150 lbft of toque at the same or similar RPM. Because the torque per pound ratio is both 20, and assuming the gear ratios are identical, would we expect both cars to accelerate identically? [link] [comments]  |

| Posted: 28 Jan 2020 07:15 PM PST I have recently read that the 2019-nCoV has ~82% sequence identity with the SARS virus and was unsure what to make of it. Considering humans and cats share ~90% of our genomes yet are phenotypically fairly different, genomic content does not seem to be a strong indicator of phenotype. I am wondering if when this is scaled down to things with much smaller genomes (e.g. viruses and microorganisms) we see a stronger correlation between the two. Apologies if this is a gross misunderstanding of the topic, genetics is not my field. [link] [comments]  |
| What would happen if you had a portal to a planet moving slower in time relative to us? Posted: 28 Jan 2020 02:50 PM PST This thought experiment has been on my mind for a while now. My limited understanding of time dilation is that objects in a strong gravitational field, or objects moving quickly, will experience time slower relative to us. So humans will age slower, clocks will tick slower, etc. Let's say we had a planet B, where time moved 10x slower than on earth. So someone would age 10 years on earth while their twin is only 1 year old. What would happen if you had a portal on earth, with an instantaneous connection to planet B, and you could look through the hole in space and see the surface of the planet. Light would be moving slower on the planet, so what would you see? A world in slow-mo? If your counterpart looked through the portal at earth, would he see a fast forwarded movie?

| Posted: 28 Jan 2020 10:51 AM PST This obviously doesn't apply to several hundred drugs (i.e. antibiotics, muscle relaxants, steroids) but drugs like anticonvulsants, endrocrine drugs, and psychiatric drugs. The medical community seems to send out a message saying "in order to maintain the effects, you must always take the drug". Yet some side effects of the drug can be permanent. Why can't positive effects or intended effects become permanent? Why does it seem, based on advice, that only negative or unintended effects of drugs are sustained? [link] [comments]  |

| Has the movement of continents from Pangea stalled or perhaps completely stopped? Posted: 28 Jan 2020 01:37 PM PST Is the progression of Pangea considered to be stopped? Other than small tectonic shifts, is it assumed the continents are somewhat stationary? If not, what does the future landscape look like? TLDR went to school in KY, ignorant about science [link] [comments]  |
| We have robotic probes for oceans and space. Do we have probes for volcanoes? Posted: 28 Jan 2020 06:44 AM PST Have we ever dropped a probe into a volcano and later retrieved it for data? Or is it simply too inhospitable for probes? [link] [comments]  |
