| Posted: 24 May 2018 04:00 AM PDT Hi, I'm Dr. Christina Nicolaidis and I'm editor of a brand new peer-reviewed journal called Autism in Adulthood. I teach social work at Portland State University and internal medicine at Oregon Health & Science University in Portland, Oregon. There's a lot of talk about autism in children, but not as much about autism among adults. That's why we just launched this new academic journal. Our goal is to cover the most pressing issues affecting autistic adults, from emerging adulthood to later life. I am particularly excited about including autistic adults in our new journal - as editorial board members, authors, reviewers and readers. As a doctor and a services researcher, my own research is focused on how people on the autism spectrum can get better access to health care services. Many autistic adults don't get the health care they need, resulting in more health problems and shorter life expectancy. Ask me anything about the new journal or the ways that people on the autism spectrum can get better care. We'll be on at 1 p.m. Pacific (4 PM ET, 21 UT), we're looking forward to the session!

| How is red shift the prove of an accelerating expanding universe? Posted: 24 May 2018 05:18 AM PDT People state in numerous video's I've seen on the subject that because stars further away are more red shifted the expansion of the universe is accelerating. But how do you know this? The light took longer to get here, isn't it also possible that the light is more red shifted in the past and the universe is slowing down. And that is why stars are less red shifted close by? I hope I'm making sense and you can help me with this question. [link] [comments]  |

| Is it possible for a nasal mucus membrane to regenerate or regrow? Posted: 24 May 2018 07:30 AM PDT Like, if the entire membrane is gone. I suppose something like a transplant would be out of the question. I want to know if it's medically possible, and if so, how is it done? Would stem cells work? [link] [comments]  |

| How do male dogs know to lift their leg to pee? Posted: 24 May 2018 07:40 AM PDT My 3.5 month old puppy just lifted his leg for the first time, and to my knowledge he's never seen another male dog do so. What's telling him to go from squatting to pee to lifting his leg if it's not learning by seeing? [link] [comments]  |

| What causes an increase in diastolic pressure with a decrease in systilic pressure? Posted: 24 May 2018 04:32 AM PDT Is there a physiological or pathological cause to this? [link] [comments]  |

| Posted: 23 May 2018 12:29 PM PDT So I'm thinking that, because the ring system is essentially a bunch of particles and rocks in perpetual orbital motion around Saturn as the barycenter, if an asteroid collided with the ring at a roughly perpendicular angle, it would leave an essentially permanent hole. Further, I'm guessing that the size of the hole would larger than the asteroids width due to the fact that it would knock some matter 'outwards' which would in turn collide with other matter causing what I'm imagining as an "orbital crater". Looking for someone to set me straight and explain what would actually happen, and if its been observed already? [link] [comments]  |

| Posted: 23 May 2018 03:12 PM PDT All I could find is about how it has a thicker cell wall, extra DNA copies, and means to repair DNA damage drom radiation. So what else is in the reactor that it can eat to survive? [link] [comments]  |

| Ask Anything Wednesday - Economics, Political Science, Linguistics, Anthropology Posted: 23 May 2018 08:12 AM PDT Welcome to our weekly feature, Ask Anything Wednesday - this week we are focusing on Economics, Political Science, Linguistics, Anthropology 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 do birds of prey not break their own bones on impact while hunting? Posted: 23 May 2018 12:10 PM PDT So as I understand it, birds have evolved over time to have hollow bones as it reduces their weight and helps with flight. However, I would assume this makes the bird's bones more brittle as a result, so how do they not shatter on impact, particularly in regards to faster species taking ground-based prey?
