| Do animals have blood types like we do? Posted: 12 Jul 2017 06:04 AM PDT We have blood types, O, A, B, and AB. Do animals of the same species have different blood types? If not, what makes us so different? [link] [comments]  |

| Ask Anything Wednesday - Biology, Chemistry, Neuroscience, Medicine, Psychology Posted: 12 Jul 2017 08:07 AM PDT 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] [comments]  |
| Do stator windings have to be angled? Posted: 12 Jul 2017 08:06 AM PDT This image from the link and many others show stator windings that are angles and not just tangential to the circle. Do they have to be this way or not? And why? Would a magnetic field not be created if they didn't have this skewed angle? http://www.hk-phy.org/energy/power/elect_phy/images/plant_generator.gif [link] [comments]  |
| Can you do RNAseq without an expensive sequencer? Posted: 12 Jul 2017 08:04 AM PDT Hi! I'm a grad student with some research questions for which I want to use RNAseq, but I can't afford to send samples to a core facility, nor can the lab afford a sequencer. Can you do RNAseq in the lab with other technology? How was RNAseq done before these $250k high-throughput instruments were marketed? Thank you very much! [link] [comments]  |
| Posted: 11 Jul 2017 05:34 PM PDT I work at a distribution center, so I essentially spend my entire shift using an RF scanner. The devices freeze up quite often, and once they unfreeze, they cycle through all the inputs you made during its downtime. What all is taking place while it's having its little digital crisis?

| Posted: 12 Jul 2017 02:41 AM PDT I'm a graduate biology student in the x-ray-crystallography field and I'm still trying to wrap my head around reciprocal/momentum space and lattices, even after reading (and not understanding too well) several source via google and books like "Introduction to Macromolecular Crystallography". I understand how to construct a reciprocal lattice (Get all families of planes with different miller indices, get their normal vector, draw the normal vector from the arbitrarily chosen origin of the reciprocal space - at the end of it is a reciprocal lattice point associated with this family of planes). I understand that reciprocal lattices are not part of real space, but are the Fourier transformation of the crystal lattice which brings it into reciprocal/momentum space (which I still can't wrap my head around after reading several sources about it, but currently just accept as being not-real-space but am not sure how to best imagine how real and momentum space interact with each other) - and of course that the reciprocal lattice in reciprocal space is the Fourier transformation of the crystal lattice. A short time ago I stumbled over this 2D visualization youtube video which made me ask myself: If reciprocal lattice points can be visualized in real space using a film of sorts - are they then diffraction maxima of the crystal lattice in real space ? Is thus the reciprocal lattice of a crystal all points in real space (not reciprocal space), that have constructive interference assuming the asymmetric unit of the crystal is a single atom? Or did I get the wrong impression based on the animation? [link] [comments]  |

| How does one sided kidney failure work? Posted: 11 Jul 2017 02:20 PM PDT Let's say only one kidney acutely failed in the body due to damage/blockage of its artery or vein. Overtime, how would you be able to tell that this is occurring? Would blood/urine tests still be normal if the other kidney remained functional? [link] [comments]  |
| Is it possible to change the way a computer handles bits? Posted: 12 Jul 2017 05:19 AM PDT So at the very base, computers work by reading and processing binary code which is done sending electrical signals though billions of transistors which in turn gives us our 1's and 0's. This in itself is amazing but I've been thinking of a way for a computer to be even faster at processing data. Instead of sending electrical signals and using transistors to represent bits, wouldn't it be better if we used light and photodiodes (I hope that's the correct component). This thought came after seeing the evolution of the way we send data, from sending data over copper wires to sending them as light pulses through optical fibres. Can the same thing be implemented with the way computers run? Given that, is it possible to store data as light? We've seen how light has been used in telecommunications but rather than using it as a way to communicate, could we use it for storage? Please correct any misunderstandings or misleading information that I may have said. [link] [comments]  |
| Posted: 11 Jul 2017 08:38 AM PDT From the article I read: One of the most difficult to grasp aspects of quantum physics is how observing a quantum particle forces the particle's state to change. This is known as the observer effect, and it is the result of the instruments necessary to measure the state of very small objects. When quantum objects, such as photons, are "entangled" it means that they were formed at the same instant in space and so share the same existence. The state of entangled particles are linked, so that if you measure the state of one particle it instantaneously affects the state of the other. Questions arise about how long it takes, if observation of one of the entangled objects can change the state of the other object, for the other object's state to change. Current research describes entangled particles as being part of the same wave function, which means that regardless of the distance between the entangled objects, the quantum state change will take place immediately. This form of immediate change is what is being described when the scientists talk about teleportation. By tangling two photons together and observing one, the scientists are instantaneously transmitting information in a potentially unlimited way. While this has been performed many times in a laboratory setting, the Chinese researcher's experiments show it to be possible to teleport an object from Earth to orbit, and breaks the record for the longest distance for entanglement.

| Posted: 11 Jul 2017 12:12 PM PDT In science fiction there are a number of instances of weapons based on using small bursts of plasma encased in electromagnetic packets and fired at the enemy. Most notably in my mind are the PPGs from Babylon 5, and the Tau Pulse weapons in Warhammer 40,000. I am curious if this has any basis in actual science, or if it is complete BS. Followup question: -If the concept is sound what scale do we have the technology to do it at? I am assuming no small arms, and my imagination has me thinking it would be particle accelerator-esque. -If it is complete BS, do we have anything similar? The closest I can think of is my very basic understanding of the Huge particle accelerators. [link] [comments]  |

| Do species with Tetrachromacy experience several colors we can't see, or just a more violet world? Posted: 12 Jul 2017 12:52 AM PDT So, I know that humans have three cones in our eyes, that can perceive red, blue, and green light. I was also reading that several species of bird have a fourth cone, that can pick up some ultraviolet light. What I'm trying to wrap my head around is just how differently they would perceive colors. Now, I know for example that we see yellow because our cones for green and red become activated in just the right amounts. But is this just finding the average of the colors based on the cone activation? If so - does that mean that if the UV cone was activated as well, the person would just see a blueish green instead, finding the average of all three activated cones? Or would this be seen as some color we can't conceive of? I suppose the TLDR is as the title says: do species with tetrachromacy see a whole ton of colors we can't even comprehend, or do they just see one extra new color, and everything else is shifted more toward violet when UV reflecting pigment is present?

| Is there a theoretical limit to the maximum size of a body of fresh water? Posted: 11 Jul 2017 11:32 AM PDT Is there a size where it would inevitably become salty? Why? EDIT: This question is about earth specifically, not just any rocky planet with water. [link] [comments]  |
