| Posted: 09 Mar 2022 04:48 AM PST I know there are loads of other places that produce oil, but a very large amount seems to come from specifically deserted or freezing places that don't easily support a whole lot of vegetation or animal life. Why is that? [link] [comments] |
| Ask Anything Wednesday - Engineering, Mathematics, Computer Science Posted: 09 Mar 2022 07:00 AM PST 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] |

| Is it possible to take neurons from the brain for in vitro studies? Posted: 09 Mar 2022 08:08 AM PST More specifically, to study neurological diseases and mechanisms. [link] [comments] |
| Does 100% oxygen saturation always contraindicate ischemia/heart failure/heart attack/angina etc? Posted: 09 Mar 2022 04:54 AM PST Or can any of these pathologies appear even in the presence of fully oxygenated blood? [link] [comments] |
| How big would a Centrifuge need to be so Gs = RPMs? Posted: 09 Mar 2022 08:10 AM PST So in terms of the centrifuge I use at work, Gs and RPMs are different. RPMs are relative to how big the centrifuges circumference is and this got me thinking, how big would a centrifuge have to be so that Gs and RPMs would be equal, if that's even possible?

| How can a part of the brain be simultaneously less active and more connected? Posted: 08 Mar 2022 08:59 PM PST A lot of research about the effect of psychedelics on the default mode network shows lower activity in the default mode network but more connectivity between the default mode network and other nodes or networks (and sometimes more connectivity between nodes in its own network). How can a part of the brain be simultaneously less active and more connected? Doesn't connectivity imply activity? I've Googled this, because it seems like it should be a simple answer, but I can't find anything. [link] [comments] |
| What do people mean by 'brain matures at 25~ish'? Posted: 09 Mar 2022 06:19 AM PST And if its a real thing, whats the average age for male population? [link] [comments] |
| Can the electron-capture decay be stopped? Posted: 08 Mar 2022 02:30 PM PST I know there's a type of radioactive decay where the electron can be capture by the nucleus, transforming a proton into a neutron. I understand radioactive decay can't be stopped, but if you strip an isotope (that decays that way) of its electrons, like plasma, can you make it stop decaying completely? I only found articles saying that chemical bonds can change the half-life, but i didn't have much luck confirming if my question is possible [link] [comments] |
| How does water form ice when under pressure? Posted: 08 Mar 2022 11:13 PM PST Traditionally, water freezes when the molecules are slowed down (due to freezing temperatures) enough for them to create stronger/stable bonds. However, I've recently been made aware that water can freeze under the right amount of pressure. From what I understand, if you pressurize water, you decrease the space for the molecules to spread out, actively lowering the melting point. Here's where I'm confused. If it's true that ice can form under pressure, does it form eventually when there's not enough space for the molecules to rapidly bond/unbond? Is that what's happening with Gliese 436 b? Is the answer that simple or am I missing something? I feel like there's a gap in my understanding. [link] [comments] |
| Posted: 08 Mar 2022 09:53 PM PST I was just looking at a photo of the Colorado river, more specifically Horseshoe bend, and I was just thinking that's an awful lot of water to be a whole river floating by and hardly any vegetation next to it. I always assumed that plants didn't grow in the desert due to the lack of water but there's a ton of water in the Colorado river flowing through this canyon but still barely any plants even right next to it. Even if the river is somewhat seasonal I would still think that plants would take advantage of all the water floating by when it was available. Is there some other mechanic I'm missing?

| What are the long-term effects of sleep deprivation in very young children? Posted: 08 Mar 2022 01:20 PM PST I'm increasingly hearing from my friends about how they're concerned with parents that just fill up their child's day with tons of stuff to do, waking them up early. I keep hearing about kids, really young kids, falling asleep in class because they have to get up so early for school. I know that toddlers and young kids around the ages of 5-9 need anywhere from 9-12 hours of sleep every night, and there are tons of kids that age and younger who get nowhere near that much sleep. It must be important for a reason that they get that much sleep. So what happens if they don't? What can we expect from kids being chronically sleep deprived as they become adults? Will this have mental health or neurological effects on them? [link] [comments] |
