| Posted: 06 Jun 2019 04:00 AM PDT For nearly 60 years, scientists have been using sophisticated technology to find proof of cosmic companions. So far, they've not turned up any indications that anyone is out there. What, if anything, does that mean? And what are the chances that we will trip across some other galactic inhabitants soon... or ever? I will be on to answer your questions at 11am (PT, 2 PM ET, 18 UT). AMA! Links:

| Is there any kind of wear (microscopic) in cables from data flow? Posted: 06 Jun 2019 12:47 AM PDT I was wondering if the fact that a cable (or fiber) is being heavily used is inducing any damage to it ? [link] [comments]  |
| How do genetics show invasion took place in history? Posted: 05 Jun 2019 10:56 PM PDT Quite often I see genetic changes in populations viewed as invasion etc Can you differentiate using genetics between a population that is undergoing invasion compared to say becoming multi-ethnic/cultural? Or is more than genetic evidence required to make this conclusion? Thanks for any help [link] [comments]  |
| Posted: 06 Jun 2019 06:44 AM PDT I've seen anecdotes online about pet cats and dogs helping lift individuals out of a depressive rut, but have there been any studies on this effect on a larger scale? [link] [comments]  |
| Which liquid has the most surface tension? Posted: 06 Jun 2019 12:43 AM PDT |
| Posted: 05 Jun 2019 06:20 PM PDT I'm curious as to how we came up with these standard values that most screen manufacturers, game creators, video rendering programs have adopted, etc. have adopted. [link] [comments]  |

| How do wolf eels retain the ability to bite after being beheaded? Posted: 05 Jun 2019 04:23 PM PDT Are they still alive, or is it because of nerves that haven't atrophied yet? [link] [comments]  |
| How would you classify what continent islands are on, such as Hawaii and St. Helena? Posted: 05 Jun 2019 05:40 PM PDT I couldn't find a good answer on google, all of them were very basic. [link] [comments]  |

| What's the difference between your skin being burned by fire, UV-rays, and ionizing radiation? Posted: 05 Jun 2019 06:18 PM PDT At a certain level of severity are they all the same or are they each radically different at every scale? [link] [comments]  |
| What is the meaning of geological process? What are its examples? Posted: 05 Jun 2019 10:58 PM PDT I've been really curious about geological processes for quite a while now and I've been searching it on internet but I'm still not satisfied [link] [comments]  |
| Do kidneys adapt to whether/regions with higher temperature? Posted: 05 Jun 2019 05:52 PM PDT It is known that after some time in a weather with much higher temperature than we are used to, we adapt by having changes in our sweating and metabolism. I do not know whether our kidneys also adapt in the long term by, for example, reabsorbing more water and producing urine with a higher concentration of solutes. [link] [comments]  |
| What do the cerebellar tonsils actually do? Posted: 05 Jun 2019 08:34 PM PDT In Chiari malformation, a portion of the cerebellum called the tonsils herniate down through the opening of the skull, interfering with the circulation of cerebrospinal fluid and increasing pressure on the brain stem. My question is this: What functional role do the tonsils play in the brain, and what neuronal tracts are they a part of? Are they functionally or histologically distinct from other regions of the cerebellum? Aside from the downstream mechanical effects due to their displacement, what implications does Chiari malformation have on their function/development? [link] [comments]  |
| Why does the western Asian region above India appear to have a much cooler climate? Posted: 05 Jun 2019 08:20 PM PDT I'm guessing elevation is a large factor. Looking for any clarification. Source example: Cool Region https://imgur.com/a/SxxlVDb Thanks ahead of time. [link] [comments]  |
| Ask Anything Wednesday - Engineering, Mathematics, Computer Science Posted: 05 Jun 2019 08:13 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]  |
