| Posted: 12 Feb 2020 11:55 AM PST I understand that this might border on violating Rule #1, but I am not seeking medical advice. I am merely curious about the effects on the body. There are lots of ways you could raise your temperature a little (or a lot if you're not careful), such as showers, baths, hot tubs, steam rooms, saunas, etc... My understanding is that a fever helps fight infection by acting in two ways. The higher temperature inhibits the bug's ability to reproduce in the body, and it also makes some cells in our immune system more effective at fighting the infection. So, would basically giving yourself a fever, or increasing it if it were a very low grade fever, help? [link] [comments]  |
| Posted: 13 Feb 2020 04:00 AM PST On New Year's 2019 NASA's New Horizons flew past a small Kuiper Belt object named Arrokoth, four billion miles from Earth, in a vast region home to the icy, rocky remnants of solar system formation. Our team has new results from that flyby, and we're excited to share what we've learned about the origins of planetary building blocks like Arrokoth. We're also happy to address other parts of our epic voyage to the planetary frontier, including our historic flyby of Pluto in July 2015. Team members answering your questions include:
We'll sign on at 3pm EST (20 UT). Ask us anything! [link] [comments]  |

| Why is thorium not used in modern nuclear reactors today? Does it have any cons? Posted: 12 Feb 2020 08:21 PM PST NOTE: I am very new to this subreddit. At the time of this post, it is currently under the Engineering flair because nuclear power plants involve engineering. If I should change the flair, don't be afraid to say so! So, today I watched a video about why thorium is better than uranium in nuclear power plants, this video to be specific. I was wondering if thorium had so many pros, why isn't it used in modern nuclear plants today? Does it have a numerous con that makes it too dangerous to put in power plants, or is it just too new? At the same time, I am wondering what are the pros and cons of thorium? The video only shows pros therefore I don't know any cons. Thanks in advance! -AsianPercival [link] [comments]  |
| How does one determine neutron energy loss per collision for molecules? Posted: 13 Feb 2020 05:38 AM PST We have found that slowing down fast neutrons to thermal levels in order to facilitate fission (as fission cross sectron increases with lower neutron energies), is done through collisions with a moderator. The energy loss of the neutron per collision is calculated as Xi = 2/(A+1) or Xi=2/(A+(2/3)) if A>10, where A is the mass number of the atom. The issue arises when we note the Xi values for heavy and light water. They do not at all follow the above formula. We have corroborated the formulas with other sources and looked around for an explanation, but found nothing. [Here](https://www.nuclear-power.net/glossary/macroscopic-slowing-down-power-msdp/) is the source we found the Xi values on, as well as the formulas [here](https://en.wikipedia.org/wiki/Neutron_moderator) Thanks beforehand for any answers!

| Posted: 13 Feb 2020 03:58 AM PST I saw some post about the sleeping patterns of famous scientists/intellectuals, and they all had extremely varied sleeping times. By that I mean, for example, 3 sessions of sleeping at various hours of the day and night, and this did not stop them from having a sharp mind. Most people nowadays would agree that it is important to get your 8h, but is there any advantage to getting a single burst of 8h at night, or is it just important to have 8h of sleep in a 24h cycle? So, I guess my question expanded would be: Does human biology dictate that we are diurnal due to the advantages it presents for our bodies, or is it just a behavior developed because we were not as effective in darkness relative to other animals?

| How quickly did life on Earth become planet-wide? Posted: 12 Feb 2020 11:30 PM PST Basically, how much time did it take for life to spread out from ground zero and become widespread across the entire Earth? By now it'd be pretty hard to find a square kilometer of the surface without life. [link] [comments]  |
| What is the relation between threshold and input resistance in neurons? Posted: 13 Feb 2020 04:23 AM PST As above, I am curious about the correlation between input current and rheobase (threshold), I think that these two variables display a negative correlation but I cannot understand why. I know that the input resistance of a neuron give an indication of the extent to which membrane channels are open. A low resistance (high conductance) implies open channels, while high resistance implies closed channels. I do not know how at high input resistance the threshold is lower than at low input resistance. Thank you in advance for your time, [link] [comments]  |
| Posted: 12 Feb 2020 10:08 PM PST I've googled this many times and asked my professor, however, I'm still a bit confused on what standard state Gibbs Free Energy actually represents in relation to a chemical system's spontaneity and thermodynamic properties. Specifically, I'm referencing the (simplified) equation G = Enthalpy - (Temperature*Entropy), not the energy of a Galvanic cell. I understand why the energy change of a system is the sum of heat and work, but what makes this different from Gibbs Free Energy, and why do we subtract the product of entropy and temperature from enthalpy? For reference, I'm a chemical engineering undergrad in their first year of studies. [link] [comments]  |
| Relationship between glycine, glutamate and GABA? Posted: 13 Feb 2020 03:45 AM PST Can someone please explain in simple terms (for one without much knowledge of neuroscience) what the relationship is, between glycine, glutamate and GABA? Please don't copy paste research articles or reviews. I've already gone through them. Thank you very much. [link] [comments]  |
| Is formation of ribosomes a stochastic event? Posted: 13 Feb 2020 07:19 AM PST Hellos, guys! Brief question: after the formation of 40S and 60S ribosomal subunits at the nucleus, is the formation of the whole ribosome biased by some specificity (meaning every 40S subunit is biased to join other specific 60S subunit) or is the formation merely stochastic??

| Why do most anticyclonic tornadoes occur as satellites? Posted: 12 Feb 2020 10:30 PM PST Can't find a detailed explanation anywhere: While I understand that an anticyclonic tornado is rare as is, what happens in the mesocyclone around a cyclonic rotation to influence the anticyclonic properties of its satellites? It makes sense to think about, a cyclonic rotation causing opposite rotations surrounding it. We see this in water - but some satellites occur as cyclonic. What is happening inside, and what decides which rotation will form? [link] [comments]  |
| How do you calculate the actual power (work being done) of a device in a AC circuit? Posted: 12 Feb 2020 11:42 PM PST How do you calculate the actual power (work being done) of a device in a AC circuit? The device is a pure resistive load. I got a new kettle yesterday, it said 2000W on the box. I took my cheapo multi-meter and it measured 30Ohms; 240V / 30Ohms = 8A and 8A^2 x 30Ohms = 1920W, close enough to what is says on the box. But it is connected to an AC power source and therefore the device will only have the full 8 Amps going through it for a fraction of the time, and so its real power must be some value lower than 1920W. I've searched a bit online and came across a "Real Power" formula "V x A x cos(phase angle)" but this formula gives me the same 1920W. My argument is something being supplied power with AC spends some time drawing current less than what it does when the voltage is at its peak. If I where to build a machine that needs a heating element of exactly 2000W, that does 2000W over time and not just at the instant the sinusoidal wave it at its peaks, how would I calculate the power of a device in an AC circuit?

| Posted: 12 Feb 2020 08:48 PM PST I remember having a great memory back when I was younger, but I have been getting hit in the back of my head more frequently and my remembering skills have gotten worse. I'd go into rooms thinking about doing something but forgetting about it, only to remember the next day. Could these hits in the head be a part of my bad memory and thinking skills?

| Are there any animals/organisms alive today that don’t fit neatly into a phylogenetic tree? Posted: 12 Feb 2020 09:58 PM PST I was wondering if we knew the rough ancestry of every species or if there were certain outliers whose ancestry we can't quite determine [link] [comments]  |
| How does sugar cause a gain in weight? Posted: 13 Feb 2020 02:01 AM PST It's commonly known to not eat too much sugar to stay healthy, but how does sugar make you gain weight? From my limited knowledge, sugar usually doesn't form lipids when polymerised. I get how eating fatty foods can cause a gain in weight, but how can sugar? [link] [comments]  |
| Does the brain grow in size/mass through neurogenesis? Posted: 12 Feb 2020 10:09 PM PST I'm taking a general psychology course and learning about neurons and how more are produced in the adult brain through neurogenesis. Out of curiosity, does the brain also grow with the growth/production of new neurons? I briefly researched this and found that sometimes *areas* of the brain can expand, but i'm more curious if the brain increases in size as a whole. [link] [comments]  |

| How long would a hydrocarbon need to be before a coil could exist? (If possible) Posted: 12 Feb 2020 03:02 PM PST Correct me if I'm wrong but 1)Hydrocarbons like to be straight or mostly straight 2)Hydrocarbons are attracted to eachother 3)Longer Hydrocarbons bend relatively easier So say you had a ten thousand carbon long alkane, and managed to somehow physically coil it 50 times or so. The coils running next to eachother should have some attraction to themselves, and the force needed to keep such a large coil should be pretty low. Could this work? If not why not?

| Does Eating Healthier Disproportionately Affect People of Low Income? Posted: 12 Feb 2020 10:17 PM PST Hello folks. I always hear that eating vegetables is better for the body and that we should eat more of them. However from an economic standpoint, is it actually feasible for people with a limited income or people that are struggling economically to purchase healthier foods like fruits and vegetables over unhealthier processed foods like easily prepared mash potatoes or fast and ready mac and cheese? I'd like to hear people's thoughts on this as I have been trying to research whether eating healthy is actually feasible economically. [link] [comments]  |
