| Posted: 25 Aug 2021 04:00 AM PDT Hello, Redditors! My name is Marc Moss, and for the last 20 years, I have been studying the effects of stress on critical care nurses and other healthcare professionals. I'm also a professor of medicine at the University of Colorado Anschutz Medical Campus, Head of the Division of Pulmonary Sciences and Critical Care Medicine at the University of Colorado School of Medicine and work as a critical care doctor. Earlier this year, my colleague Dr. Meredith Mealer and I were honored to receive the American Association of Critical Care Nurses (AACN) Pioneering Spirit Award for our work studying the effects of stress on nurses and creating interventions to increase resilience among healthcare workers. Among these interventions includes work at the Colorado Resiliency Arts Lab, a research consortium supported by the National Endowment for the Arts. We are striving to create a vibrant, collaborative creative arts therapy community that is committed to enhancing healthcare professional well-being and alleviating psychological stress in the workplace and beyond. While I've been studying healthcare-related burnout for many years, this last year and a half during the COVID-19 pandemic has been a war zone for our healthcare professionals. I have never been prouder of all of my colleagues and the amazing hospital employees that we work with on a daily basis. They are working long hours in difficult conditions, putting on and taking off protective equipment, while trying not to get sick themselves, or infect their families and children. You would be honored to witness their extraordinary and relentless efforts to care for our sickest patients. However the relentless stress is taking its toll on all of us. I am afraid that the next wave will "break our souls". In addition to critical care-related research, my research interests include identifying new treatment modalities for patients with the Acute Respiratory Distress Syndrome (ARDS) and exploring the diagnosis and treatment of neuromuscular dysfunction in critically ill patients who require mechanical ventilation. I will be on at 1pm ET (17 UT) to answer your questions, AMA! Additional Background:

| Posted: 24 Aug 2021 07:54 PM PDT Is it only the lack of oxygen in the atmosphere? What if a comet with a high quantity of frozen oxygen were to impact Titan at high velocity? Basically what's the easiest way to detonate all that gas on Titan? Is it even possible? [link] [comments]  |
| Ask Anything Wednesday - Engineering, Mathematics, Computer Science Posted: 25 Aug 2021 07:00 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]  |
| Why is the Strait of Gibraltar so much deeper than the area surrounding it? Posted: 24 Aug 2021 08:43 PM PDT I couldn't find a reliable answer online and I am not sure if this counts as science, but I'm curious to why the Strait of Gibraltar is so deep in such a specific spot in the world.

| Why don't we just digest harmful bacteria like salmonella instead of getting sick? Posted: 25 Aug 2021 06:31 AM PDT Salmonellosis is from bacteria. Bacteria are built from some of the same basic components as multicellular organisms, which we break down with specialized enzymes along the digestive tract. But ingesting these bacteria, our body seems to just allow them to get to work instead. How is this? [link] [comments]  |
| Is the microbiome of one ear significantly different from the other? Posted: 24 Aug 2021 08:21 PM PDT Sometimes I'm guilty of using q-tips. Is there every a chance of cross contamination between ears? [link] [comments]  |

| If centrifugal force is a virtual force, then how does it cause any change? Posted: 25 Aug 2021 07:43 AM PDT Hi I'm a high school (age - 15) student, and recently I learned that centrifugal force doesn't really exist and it's just assumed by the observer. But we were taught that centrifuge works on the principle of centrifugal force and also that earth bulges at centre and it flattened at poles due to the action of this force. But if it does not exist, how do these changes occur? It would be really great if you use simple terms because I don't think I'm very well versed in physics and neither much acquainted with technical terms. [link] [comments]  |

| How long are waves far out at sea? Posted: 24 Aug 2021 06:48 PM PDT I always hear a lot about the height of waves. I've also just come to know about 'rouge waves' , which blew my mind a bit. But how far can/do they stretch? Is it the entire length of the ocean or am I being stupid? [link] [comments]  |
| Is Focus/attentiveness measurable? If so how? Posted: 25 Aug 2021 04:50 AM PDT If two people are working on the same task, and person 1 is thinking about food/naked women/drugs etc while working. And person 2 is fully engaged in the task. Not even noticing other people in the room. [link] [comments]  |
| What was Mars like during periods of high tilt? Posted: 24 Aug 2021 03:13 PM PDT I've heard a bit about how high tilt on Mars probably caused the loss of polar ice caps and the accumulation of ice near the equator. What would Mars have been like in these periods, in terms of weather, atmospheric density, and just overall appearance? How frequently do periods of high tilt occur and when was the most recent one?

| Does the type of sand matter for glass production? Posted: 24 Aug 2021 11:55 PM PDT Read a report that if not for plastic-glass hybrid vials, we nearly didn't manage to mass produce vaccines in such a short time. I understand not all sand are created equal, for example, dessert sand is smooth hence not suitable for construction. Construction requires rougher/angular sand from rivers etc. Controlling for variables like shipping bottlenecks and time it takes to start glass manufacturing facilities, it shouldn't matter what type of sand is used for glass production right? I am thinking glass production requires the melting of sand that changes it on a molecular level, hence the shape of the sand on the microscopic level shouldn't be a limiting factor. Am i right? Or am I missing something? Edit: this is the excerpt from an article that got me thinking about this: "Part of the problem is that glass manufacturing facilities are expensive to build. Then, there can be challenges with obtaining the needed key raw material — a particular kind of angular sand found in riverbeds and beaches that's in high demand around the world for a number of products."

| What if the human body doesn't have any T cell that can bind to a particular antigen? Posted: 24 Aug 2021 11:54 AM PDT So T cells develop in the thymus during childhood where the antigen binding receptors on them are tested in positive and negative selection so that they don't hurt the body. After the thymus effectively stops working (not completely) you are effectively stuck with the antigen binding receptors from your childhood. We know in order to activate an adaptive response of the immune system T cells need to activate B cells. But if you have a pathogen that doesn't have an antigen which your childhood setup of T cells can bind to then no T cells are activated and therefore no B cells which means there is no antibody production and hence no adaptive immune response?? Would you die then? Is this why so many people die to the flu virus? Is there a way for the body to circumvent this? Is that the reason for why some people have faster adaptive immune responses to certain viruses and therefore have a higher chance of survival? While the people that by random chance had fewer T cells which could recognize this particular antigen and therefore the chance that these T cells would be in a lymph node further away from the first antigen presenting cells would therefore have to wait a longer period for the antigen presenting cells to reach the T cells and therefore delay the adaptive immune response? Please try to answer my question in detail and correct me If I made incorrect assumptions. [link] [comments]  |
| Determining the type of decay an isotope undergoes when it has multiple options? Posted: 24 Aug 2021 09:47 PM PDT This question stems from the decay modes of Hydrogen-6 and how it can either decay via triple or quadruple neutron emission to give either deuterium or tritium. How is it determined which mode of decay happens? As a slight follow up... When the half-life of a particular isotope (let's keep using Hydrogen-6) is defined in yoctoseconds as follows: "294(67) ys" - What is the significance of the bracketed numbers? Many thanks in advance and sorry for the double question, I figure the second one is likely to be trivial to answer. [link] [comments]  |

| What is the "Overlapping Map Theorem," or whatever it's really called? Posted: 24 Aug 2021 01:59 PM PDT I remember hearing about this math/geometry concept where if you were to take two maps of an identical place, even if they're different sizes, then lay one over the other, there will always be a point at which you can place a pin that it will be the same proportional coordinates. I can't find anything by searching "overlapping map theorem" or the like. This concept was illustrated by the fact you could take any map of the US anywhere in the country, lay it on the floor, and essentially place a "You are here" marker that would also exactly hit the hole in the map itself were an enormous scale pin to drop from the sky. Does this work for any rotation as well? What if one of the maps is not completely on top of the other? I thought of this as I was importing some photos into a project into Photoshop. They were all the same size, but some of them had erroneously rotated due to the camera tilt sensor being tricked or something since I was shooting straight down onto a table. I wondered if - instead of rotating and then readjusting position - I would have been able to use this concept to reset the center of rotation around a certain point that would have seen the image placed perfectly without directly shifting position. This would be the case if I would be able to find a point that wouldn't move coordinates from one orientation to another. Obviously it would be too computationally intense for my needs, but I'm still curious. [link] [comments]  |
| How much of the COVID-19 does it take to make one sick? Posted: 25 Aug 2021 03:00 AM PDT |
| Posted: 24 Aug 2021 09:34 PM PDT I know you're not considered fully immunized until 2 weeks after your 2nd shot. For those getting the third shot, when do those neutralizing antibody levels start to rise? Is it also 2 weeks? And is it a more gradual process? As in, each day more antibodies are formed?
