| When do deep-ocean thermal vent animals sleep, if at all? Posted: 10 Jul 2018 06:33 PM PDT It has occurred to me that life around those deep ocean vents is unable to see the sun and is not reliant on it as an energy source, and so would have difficulty telling day and night. When do animals there sleep? I would imagine that at least some of them require it, because some of those animals are fish, which if I recall correctly do need sleep. [link] [comments]  |
| Posted: 11 Jul 2018 04:00 AM PDT Hello, Reddit. I am Dr. Michael Smith, WebMD's chief medical director. Have a question about ticks? We'll cover everything from ways to protect from tick bites to first aid steps to take if one bites you. AMA! Hi Reddit, we are John Aucott, and Mark Soloski and we are researchers at Johns Hopkins Medicine studying ticks and Lyme disease. Ever wonder why Lyme disease and other tick-borne infections have become so common? What makes some people get sicker than others? And how can we prevent and diagnose Lyme disease - that the classic bull's eye target is not as common as people think? We cover everything from fundamental research to clinical treatments - AUA! We will begin answering questions at 12pET (17 UT). Ask us anything! [link] [comments]  |

| Is there a compound that can be found naturally but cannot be made artificially? Posted: 11 Jul 2018 01:48 AM PDT Just shower thoughts, probably none. Scientists can do their magic. [link] [comments]  |
| What killed the prehistoric sea monsters? Posted: 10 Jul 2018 06:15 PM PDT The asteroid killed the dinosaurs, but did that also kill off those massive sea creatures? If not, why are they mostly not around anymore? [link] [comments]  |
| Why do our voices become deeper and more coarse when we get a cold with a lot phlegm? Posted: 10 Jul 2018 07:10 PM PDT |
| Why does it take our eyes longer to adjust from light to dark than from dark to light? Posted: 10 Jul 2018 05:53 PM PDT Turning off lights in a room, will take eyes a few minutes to adjust and start to make out objects. turn light on and after initial sudden flare in eyes we can see everything.

| Ask Anything Wednesday - Biology, Chemistry, Neuroscience, Medicine, Psychology Posted: 11 Jul 2018 08:12 AM PDT Welcome to our weekly feature, Ask Anything Wednesday - this week we are focusing on Biology, Chemistry, Neuroscience, Medicine, Psychology 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]  |
| How is micron size particles measured? Posted: 11 Jul 2018 04:13 AM PDT Polishing test samples for work and we use polishing paste that goes down to 0.04 microns. How is is measured and controlled? [link] [comments]  |
| How thick (bars) would Earth’s atmosphere be compared to Venus, if all the oceans evaporated? Posted: 10 Jul 2018 04:31 PM PDT Venus' atmosphere is 93 bars, so it is just under 93 times thicker than our atmosphere at sea level, if I am understanding the concept of a bar correctly. But if all our ocean's evaporated, how much thicker would our atmosphere be at sea level? (Well, formerly sea level...) What formulae/approaches could be used to determine this? [link] [comments]  |

| Why do lower energy, low frequency waves travel further than higher energy, high frequency waves? Posted: 10 Jul 2018 05:21 PM PDT EDIT: Oops I meant to say sound waves, specifically. And in particular, I'm interested in what happens at a molecular level. Why wouldn't the higher energy waves travel further, because they have more energy? How is it that something with a lower energy travel further? The way I understand energy, is you need more energy to travel further, like adding gas to a car. So how would something with less energy travel further? [link] [comments]  |
| Where did all the water come from? Posted: 10 Jul 2018 07:41 PM PDT Presumably there was a time without water on Earth and now there are oceans of it. Water doesn't appear spontaneously as far as I know. Edit: redundant sentence [link] [comments]  |
| Posted: 10 Jul 2018 10:14 AM PDT How easy would it be to fatally damage or crush a newly fertilized human egg with the (what's it called?) prodding instrument? I want to be accurate in the book I am writing, and I can't find answers online. So your help is much appreciated! [link] [comments]  |
| Are there any non alternating, infinite series', that diverge slower than the harmonic series? Posted: 10 Jul 2018 01:57 PM PDT The harmonic series already diverges extremely slowly, I was wondering if there were any other series' that diverge slower than the harmonic. [link] [comments]  |
