| Posted: 06 May 2020 04:00 AM PDT Hi! I'm Jane McGonigal. I'm the Director of Game Research and Development for the Institute for the Future in Palo Alto, California. I believe game designers are on a humanitarian mission - and my #1 goal in life is to see a game developer win a Nobel Peace Prize. I've written two New York Times bestselling books: Reality is Broken: Why Games Make Us Better and How They Can Change the World and SuperBetter: The Power of Living Gamefully. I'm also a lifelong game designer (I programmed my first computer game at age 10 - thanks, BASIC!). You might know me from my TED talks on how games can make a better world and the game that can give you 10 extra years of life, which have more than 15 million views. I'm also the inventor of SuperBetter, a game that has helped more than a million players tackle real-life health challenges such as depression, anxiety, chronic pain, and traumatic brain injury. SuperBetter's effectiveness in treating depression and concussion recovery has been validated in clinical trial and randomized controlled studies. It's currently used by professional athletes, children's hospitals, substance recovery clinics and campus health centers worldwide. Since 2018, the SuperBetter app has been evaluated independently in multiple peer-reviewed scientific articles as the most effective app currently in the app store for treating depression and anxiety, and chronic pain, and for having the best evidence-based design for health behavior change. I'm giving an Innovation Talk on "Games to Prepare You for the Future" at IBM's Think 2020. Register here to watch: https://ibm.co/2LciBHn Proof: https://pbs.twimg.com/media/EW9s-74UMAAt1lO.jpg I'll be on at 1pm ET (17 UT), AMA! Username: janemcgonigal [link] [comments]  |

| Ask Anything Wednesday - Engineering, Mathematics, Computer Science Posted: 06 May 2020 08:10 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]  |

| How fast do disinfectants actually kill pathogens? Posted: 06 May 2020 04:01 AM PDT So I always imagine that when you pour/wipe Dettol or alcohol on something, the pathogens it targets are destroyed within seconds. I always get into this argument with my family, who insist that you should leave whatever it is you're cleaning to soak in the disinfectant. I mean, it's not like the cell membranes or virus proteins are waiting around, as soon as the liquid touches pathogens they should be destroyed, right? tl;dr: How fast do they kill that "99.9% of bacteria"? Is there any benefit to leaving things to soak in Dettol or other liquid? [link] [comments]  |
| Posted: 06 May 2020 08:29 AM PDT Are there viruses (probably non-human) that already do that? [link] [comments]  |
| Posted: 05 May 2020 11:08 AM PDT The question is really around using something other than a disease to help someone generate antibodies. That is to say, if we could figure out the genetic sequence (call it Sequence Y) used by B-Cells (or are they stored in marrow?) to produce antibodies for Disease X, instead of figuring out how to attenuate disease X to use as a vaccine, could we instead have a universal virus as a carrier that does nothing but inserts Sequence Y into the B-Cells of a host? Would this be a more effective way of getting a population to produce antibodies for Disease X? [link] [comments]  |
| How rigid are the angles between ions in molecules? Posted: 06 May 2020 04:55 AM PDT Water molecules, of course, have that distinctive angle between the hydrogen cations, but how fixed is that angle? Can it wiggle a bit or is it set in stone? Obviously it likes to hang out in that arrangement, but why? Is that just the closest to equilibrium it can be? Are there any molecules that 'don't really mind' where there constituents are hanging out? Or is there any sort of gradient between how fiercely ions will fight to maintain a certain arrangement? Proteins, as well, have very complex arrangements, with lots of angles and interactions. If one was to bump into something, would it physically bounce a little? Is it possible for a protein to denature due to mechanical processes? Sorry, I know its a lot of little questions, but I think they all get down to the same basic concept. [link] [comments]  |
| How would people in the past deal with orthopedic injuries requiring surgery? Posted: 06 May 2020 04:55 AM PDT Looking at some old Derrick Rose videos on YouTube, I thought to myself nowadays we're so privileged to be able to have our knee ligaments stitched up with relatively basic surgery. However, people have been tearing their tendons and ligaments for thousands of years. How would people deal with a torn achilles 2000 years ago? Would you just be crippled for life? Were there any methods to alleviate such injuries? [link] [comments]  |

| Do we live in Euclidean space? Posted: 06 May 2020 06:59 AM PDT Or is the Euclidean space just a very good „approximation" of our space? And if the answer is yes, how do we know? Which property's about the space we live in do we know? Do we know the metric? I'm a math student so just something I thought about. Thanks for (if) replying! [link] [comments]  |
| What is limiting microbial growth at high pH? Posted: 06 May 2020 05:24 AM PDT Hello , I was looking into the overall limits of microbial growths. I can find a lot about how alkaliphiles cope with a high pH, but I did not find a definite answer to what biological component will be the limiting factor. I am especially interested in why the proton gradient upkeep will fail with increasing pH. I found some sources about Na-ATPases, that don´t use H+ that would just react with extracellular OH- forming water. But this is a work around. Is it the intracellular pH, that can only be buffered to a certain level until the protein synthesis fails? Thank you for your answers [link] [comments]  |
| When did the scientific community learned that there is no (at least not macroscopic) life on Mars? Posted: 06 May 2020 05:04 AM PDT I wonder if there was a time when the scientific comunity considered the possibility of the existence of macroscopic life on Mars, such as Martian plants and animals (or equivalent). When did we learn that this is not the case? [link] [comments]  |
| Posted: 06 May 2020 04:47 AM PDT Basically what the title says, I'm thinking at a level such as Google street view? Is it possible to create such a telescope? If so, what is stopping us? If not, why? [link] [comments]  |
| Posted: 06 May 2020 12:31 AM PDT https://en.wikipedia.org/wiki/Silicon_nitride So, if this is true, does this mean if it was dropped into a star (for example) or otherwise exposed to extreme heat, would it remain a solid even there? (excepting things like effect of pressure). [link] [comments]  |

| How does ionization state affect radioactive decay rates? Posted: 05 May 2020 05:54 PM PDT I was taking a stroll through Wikipedia and came across this:
...So there is one isotope of Technetium that is or is not stable depending on its ionization state. Is it normal for ionization state to affect the half life of radioactive isotopes? How does it work? And is that useful information or just a curious little detail? [link] [comments]  |
