- We are able to catch the common cold year after year so does that mean that the viruses (rhinovirus and—to a lesser extent—Coronaviruses) mutate fast enough that we don’t ever develop full immunity to them analogous to influenza? If so, why isn’t the common cold much more severe?

| How do electrons get separated from the Hydrogen atom in a Fuel Cell? Posted: 05 Feb 2020 02:30 AM PST I know theres a platinum plate that the hydrogen hits, and a membrane that only the hydrogen ions can pass through, but I don't understand how the electrons separate. All research only states they "get separated" but fails to explain why it separates. [link] [comments]  |
| Posted: 05 Feb 2020 03:49 AM PST I might be terribly wrong but I just thought of this based on Coulomb's Law. The r or radius/distance in the equation could be replaced by any large number and the electric force would still not be zero albeit so low that it's negligible. [link] [comments]  |
| Posted: 04 Feb 2020 12:02 PM PST Serious question, I know climate change and the melting oft the ice caps leads to a general rise of the sea level, please don't put me in a corner with people who doubt that fact. I came across records from the coast of the island Usedom today (was looking into something related for work) and it may be a stupid question, but I thought you could see the sea level rise, but there wasn't much of a trend in the data. Is the time period of 60 years too short? Or are there other reasons for this, like tectonic movements or the fact that the water exchange with the Atlantic Ocean is limited? [link] [comments]  |
| Ask Anything Wednesday - Physics, Astronomy, Earth and Planetary Science Posted: 05 Feb 2020 07:09 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]  |

| Why does light turn blue the more lumens there are? Posted: 04 Feb 2020 10:49 PM PST The post in reference that got the question in my head Is this like a "a blue flame is hotter than a red one" kind of thing? And if so, why specifically blue? What is it about the color blue that allows for hotter temperatures to be presented? [link] [comments]  |

| Why does the Earth's magnetic field flip every hundred thousand years or so? Posted: 04 Feb 2020 08:40 AM PST I'm taking a college class on Origins of life on earth and the possibility of ET life. In one of my professor's lectures on earth history he mentioned that the earth's magnetic field flips every 100,000 years or so. I thought he was going to explain further but he moved on. So what is he talking about? And what are the effects on earth when it happens? [link] [comments]  |
| Posted: 04 Feb 2020 12:42 PM PST Since the grey matter is primarily neuronal and not axonal would degradation of it cause an overexpression or underexpression of things such as fight or flight, fear conditioning, etc? [link] [comments]  |
| Why are bats so often considered likely suspects for new diseases infecting humans? Posted: 04 Feb 2020 10:43 AM PST So, when a previously unknown disease is discovered, quite often bats are named as liley sources or at least potential sources for these viruses. I also heared that they are a reservoir for mumps and other diseases. It seems strange that bats are more likely to be hosts of viruses harmful to humans than let's say rabbits or cats. So are bats special and if yes, why? [link] [comments]  |

| Which species of micro-algae is used to produce algal biofuels? Posted: 04 Feb 2020 10:27 AM PST I'm specifically looking for the species that produces the most amount of lipid content over time. Thank you in advance. [link] [comments]  |

| Posted: 04 Feb 2020 11:59 AM PST Lets assume there are no major planets, could we perhaps have a system with a main central star and 10+ or so smaller stars orbiting similar to planets or perhaps 2 stars orbiting each other closely and a third far out orbiting the center of mass and then repeated for a 4th and so on many more times. I know binary systems are pretty common with some systems having 3 or 4 stars but I was wondering if a system would just become unstable no matter what given enough stars. [link] [comments]  |
