| How do the Japanese Snow Monkeys dry off without dying once they leave the hotsprings? Posted: 29 Apr 2020 04:19 PM PDT How do the monkeys not get hypothermia being in the winter air soaked in water once they leave the hotsprings? It seems every nature show wants to show this human like behavior but not any of the other behaviors of the species. [link] [comments]  |
| Do quasars exist right now (since looking far into deep space means looking back in time)? Posted: 30 Apr 2020 05:23 AM PDT Quasars came into existence within 1 billion years after the Big Bang. The heyday of quasars was a long time ago. The peak of quasars corresponds to redshifts of z = 2 to 3, which is approximately 11 billion years ago (or 2 to 3 billion years after the Big Bang). They were thousands of times more active than they are now. But what does 'now' mean, in terms of relativity? When we observe quasars 'now', we look back in time, and thus see how they were a very long time ago. So aren't all quasars in the universe already gone? [link] [comments]  |
| Are there viruses that you don't become immune to after recovering? Posted: 29 Apr 2020 03:41 PM PDT How common are they? also i understand that you can become immune for a few weeks after recoviring from certain viruses. how common are those as well? do most viruses cause long-term immunity after recovering or short term?

| Posted: 29 Apr 2020 11:12 PM PDT I've been thinking of this question knowing that the speed of light is the fastest an object can travel. Hypothetically, if there was an absolutely massive "fan" in space, with blades that are astronomical units long, that was spun at a high rate of speed, what would happen to the edges as they approached the speed of light? Why can't they go faster? Even if the speed at the center of the fan is slow, the speed would increase exponentially as the distance from the center increases. Say the material is infinitely strong and would hold its shape at this speed. [link] [comments]  |

| Posted: 30 Apr 2020 08:12 AM PDT The lock down measures world wide, I have to imagine, provides a unique opportunity for scientists to collect data that they could not collect under normal circumstances. Am I correct in believing that? If so, what research is occurring now, not directly related to the pandemic itself, that may have been otherwise impossible to conduct before the pandemic?

| What sort of biology do you find under huge areas of concrete/ashphalt? Posted: 29 Apr 2020 09:03 PM PDT I hope I'm asking this right and it makes sense Especially super massive parking lots or the dry parts under cities. Lots of places under cities you get parts with higher biomass where there is water and artificial lights, rats and cockroaches and the like are famous for that, but what I mean are the desolate places. It also would also it depends on climate/where in the world I mean so I'll settle with places that don't freeze in the winter, but if there is similarity or something of note that would be interesting too. I guess in very cold places you might get unusual (for the area) life as the heated buildings might keep certain parts from freezing, just as cities in cold climates are always 5-10 degrees warmer than surrounding rural areas So those ginormous parking lots probably have huge areas without pipes or tunnels and so they would be like a desert and the only water source would be where there are cracks or potholes that allow water to get to the soil like an oasis, maybe at most you would get algae, fungi and maybe some microfauna? Are there any special microorganisms that thrive in these conditions? It would be a bit like a dark desert with oasis right? Does anything live of even thrive in the dry parts? Would they be considered as extremophiles? Thanks in advance :) [link] [comments]  |
| How are drugs like remdesivir specific to viral RNA? Posted: 29 Apr 2020 10:48 PM PDT I don't understand how a nucleotide analog like remdesivir can interfere with the function of viral RNA polymerases and not our own. [link] [comments]  |
| Is it actually possible to create a fusion reaction without stellar gravity in the equation? Posted: 29 Apr 2020 03:00 PM PDT I've heard of possible solutions for Earth-based fusion reactions, but the common issue with nearly all of them seems to stem from the fact that the amount of energy required to even feasibly create and control plasma, on top of extracting and using its energy, often entirely defeats the purpose of the reactor in the first place; there's always a substantial net loss of energy in this transaction. So is this just a pipe dream that we'll never be able to solve? Are we better off harvesting energy from the sun directly and leaving it at that? [link] [comments]  |

| Do similar or the same thoughts produce similar or the same electrical signals that we can discern? Posted: 29 Apr 2020 06:42 PM PDT I'm not going to be able to use the right words here since I'm just a dumb dumb business major but I'll do my best to get the questions across. If I think of the word "apple" while my brain activity is being recorded/monitored/imaged/whatever you call it... and then later think of the word "apple" again, will that brain activity look exactly the same? That's the main question, follow ups are... If the answer is yes, does that mean someone could look at the activity in real time or afterwards and be able to tell I am/was thinking about the word "apple" just based on the thing they're looking at? Again if yes, will that always be true across my life or does that change over time and/or perception of the word? What about if instead of the word, I think of what an apple looks like. Will that activity look related to me thinking of the word "apple"? If all or any of that is true.... If someone, somewhere else in the world, that I've never met also thinks about what an apple looks like, will the activity look similar? I could go on and on with questions on this curiosity but in the event the answer to the main question is "no" I'll stop here. Thanks a bunch for helping me to understand without knowing the words science people! [link] [comments]  |

| Is the brain sexually dimorphic? Posted: 29 Apr 2020 06:36 PM PDT I recently got into a discussion with a family member about wether or not the brain was sexually dimorphic or not, and they sent me links to three studies that claim to demonstrate that the brain isn't sexually dimorphic at all. Are the articles accurate in their claims? [link] [comments]  |

| What is it about nuclear reactions that allow for mass to be converted to energy? Posted: 29 Apr 2020 12:57 PM PDT I was giving my family the basic explanation for fusion vs fission and how E=MC^2 means small mass --> big boom. But I never really stopped to think why does that conversion happen? Or more specifically: What are the conditions that allow mass to be converted to energy and vice versa? In chemistry we talk about reactions occurring if you can reduce the free energy of the system (- ΔG ). Is a similar process occurring here where it is more "efficient" to convert to pure energy rather than resist the extreme temperatures? [link] [comments]  |
| Do animals have to learn how to swim like humans or are they just born with that ability? Posted: 29 Apr 2020 06:36 AM PDT Swimming in humans is something that must be taught and it is not something that we are just instinctively able to do. Do animals like jaguars or tigers that swim and use the water for hunting but are not dependent on water have to teach their young how to swim? If these types of animals are not exposed to water or not taught by their parent, do they instinctively know what to do or would they drown? [link] [comments]  |
