| What happened to the UPMC so-called "suspended animation" trials in Pittsburgh? Posted: 03 Nov 2015 09:46 PM PST The program was revealed over a year ago through the media. There was a post in Reddit about a year ago, asking for clarification. A quick Google search reveals nothing but the press releases from 2014. Has it been a simple lack of viable candidates, or are the results simply not published yet? [link] [1 comment]  |
| Why is the EmDrive considered impossible if it actually emits electromagnetic waves? Posted: 03 Nov 2015 05:44 PM PST EmDrive is supposed to be "impossible" due to the fact that is does not expel any matter to propel it. But wouldn't it work in the same way as a light sail, although instead of just reflecting (or absorbing) the light, it would emit it, right? (assuming it work -in short- by bouncing electromagnetic waves) [link] [22 comments]  |

| Ask Anything Wednesday - Biology, Chemistry, Neuroscience, Medicine, Psychology Posted: 04 Nov 2015 07:02 AM PST 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] [1 comment]  |
| Can Coronal Mass Ejections push/propel the sun? Posted: 03 Nov 2015 11:28 PM PST Google let me down on this one, hopefully reddit can provide the goods [link] [3 comments]  |

| From an outside observer, does matter pass through a black hole or not? Posted: 04 Nov 2015 06:00 AM PST I've seen examples about black holes, objects passing through them; the most common one: a clock passing through a black hole. From the clock's perspective, it just passes through the black hole like nothing, I think; but, from an outside observer, it will slow down as it approaches to the black hole, and it will reach the point where it will stop because the gravitational force is so strong that dilates the space and time. So, if matter will eventually stop, why don't we see matter placed at the middle of black holes? Does matter really pass through them or not? [link] [1 comment]  |
| Can a side effect of global warming also be more extreme winters? Posted: 03 Nov 2015 11:48 PM PST For some reason I've always had the idea that if the summers are getting hotter than it would follow that the winters would be colder. I'm not sure where I picked up this idea or if I just assumed it. I don't know if this makes sense or is even correct, but it's one reason why when I hear arguments against climate change talking about how it snowed a lot last winter so global warming can't be real, it just doesn't make sense to me. Can anyone tell me if this actually happens because of global warming? If so, what causes it? [link] [18 comments]  |
| Is ∇·velocity(x,y,z) = acceleration ? Posted: 04 Nov 2015 05:27 AM PST ∇·v = ∂/∂x [vx] + ∂/∂y [vy] + ∂/∂z [vz] = ax + ay + az = a? Am I getting this right? [link] [5 comments]  |
| To what extent can caffeine compensate for the short-term cognitive effects of sleep deprivation? Posted: 03 Nov 2015 09:52 PM PST Like lack of concentration. And not full sleep deprivation, just getting a few hours of sleep a night. [link] [1 comment]  |

| What is the origin of nicotine in nicotine gum? Posted: 03 Nov 2015 06:22 PM PST Is it tobacco, concentrated or distilled down? I've heard there's nicotine in all kinds of things such as eggplant too... [link] [2 comments]  |
| What is the thermal conductivity of a perfect vacuum? Posted: 03 Nov 2015 07:51 PM PST Perhaps a better (more correct) way to word it, how does a vacuum's ability to transfer thermal energy compare to, say, air? Assume we had a water bottle, how better of an insulator would a vacuum be compared to an insulating layer of air? [link] [4 comments]  |
| Do electronics pull electricity, or do sockets/chargers push it? Posted: 03 Nov 2015 10:03 PM PST I was reading about some issues with some USB C chargers, and one thing mentioned was that the devices expects a higher amperage than the charger is outputting, which would damage the charger, and am now confused, how does charging actually work?
