| Ask Anything Wednesday - Physics, Astronomy, Earth and Planetary Science Posted: 11 Nov 2020 07:08 AM PST Welcome to our weekly feature, Ask Anything Wednesday - this week we are focusing on Physics, Astronomy, Earth and Planetary 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]  |

| What is the efficacy of normal vaccines? Posted: 11 Nov 2020 07:51 AM PST With the announcement of the potentially "90% effective" Covid vaccine, I was wondering what the efficacy was of other vaccines. What is the normal percentage to allow a vaccine to become licensed? How about the MMR for example? Also, though this will likely get answered, have they reduced the required standard to try and help with the pandemic? Thank you! [link] [comments]  |
| Why are there so many Annular Lakes in Quebec? Posted: 10 Nov 2020 07:39 PM PST While doing just a quick fly over on Google Earth of the Canadian province of Quebec, it is quite easy to spot the preponderance of almost perfectly circular lakes dotted around. If they are named, like lake Manicougan, it says that it is an Annular lake that was formed by an asteroid impact at some point in the Triassic period. I am assuming asteroids throughout the history of Earth didn't have a bias to strike in areas that would become modern day Quebec, so I would guess the rest of the Earth has been bombarded to a similar degree as the preponderance of these lakes in Quebec. But why has Quebec in particular and maybe a few other places on Earth preserved these scars so well while they have vanished everywhere else? [link] [comments]  |

| Why are fingerprints so elaborate and unique? Posted: 10 Nov 2020 06:09 PM PST How did they develop and evolve to become so? Do they serve any particular evolutionary function in being as elaborate and varied as they are? [link] [comments]  |

| If fever is a natural response to a pathogen, why is it not a symptom of every infectious disease? Posted: 11 Nov 2020 05:13 AM PST I recently learnt about the immune system in science and learnt that the second line of defence includes fever and inflammation. Why is it that for some infectious diseases (e.g. COVID-19, Influenza, etc.) fever is common, but for others (e.g. Common cold, impetigo, etc.) it's rare, only happens in severe cases, or doesn't happen at all [link] [comments]  |
| Could the mRNA method be used on other viral infections? Posted: 10 Nov 2020 09:30 AM PST Given the promising efficacy of the mRNA COVID-19 vaccine, could this method see a faster adoption for use in vaccines for other viral infections? [link] [comments]  |

| What actually are Conduction and Valence bands? Posted: 11 Nov 2020 01:17 AM PST I understand how the bands and the energy gaps work differently for different nature of materials, however, one basic thing which I failed to understand was that what actually are these bands? Most of the diagrammatic representation shows them as a rectangular energy band, so if that's the case, what's the difference between these bands and different energy levels (n=0,1,2...) ?

| Posted: 10 Nov 2020 07:51 PM PST For globular clusters to stay spherical, I expect that the motion of the stars in the cluster must be fast enough to overcome the gravitational pull toward the center of the cluster. But does each individual star orbit he center on a different plane? [link] [comments]  |
| Carcinisation- Is it true at all, do other creatures experience it? Why does it happen? Posted: 10 Nov 2020 10:29 AM PST I have recently read about Carcinisation, which is said to be an example of Convergent Evolution, in which crustaceans evolve from non crab-like forms into crab-like forms. L. A Borradaile described it as "one of the many attempts of nature to evolve a crab" Is this valid, or true? Why does it happen? And are there any other life-forms that experience a similar phenomena? [link] [comments]  |

| What actually is quantum entanglement? Posted: 10 Nov 2020 09:26 PM PST Are they really "entangled"? could they be used to transmit information? [link] [comments]  |
| How can a vaccine work for someone but not another? Posted: 10 Nov 2020 03:24 PM PST For example: Pfizer's vaccin is 90% effective, but why it isn't effective on some people? [link] [comments]  |
| Posted: 10 Nov 2020 08:30 PM PST I was watching a video, and it all made sense up until this part; https://youtu.be/qm67wbB5GmI?t=522 How the hell do we create kilometers of miniscule copper wires, all perfectly connected to billions of transistors, within a space smaller than your fingernail? [link] [comments]  |
| Why does Pfizer's Covid 19 vaccine require very low temperature storage? Posted: 10 Nov 2020 11:13 AM PST What is it about the vaccine that is vulnerable to higher temperatures? Are there other medicines which require ultracold? [link] [comments]  |
