| Why is it so important to finish the whole course of antibiotics? Posted: 06 Jan 2020 04:27 PM PST Hey guys, so I got into this debate with my friend who told me he stops taking his antibiotics once he starts feeling better. Naturally I was horrified but when he kept questioning it, I couldn't really explain why it was so important for him to take the full course. Could anyone explain what the dangers are when people don't finish their prescribed course of antibiotics? EDIT: thank you so much for all the comments and resources! I'll pass them on to my friend and hopefully he'll believe it's more than just "big pharma propaganda" lol. [link] [comments]  |

| Posted: 07 Jan 2020 06:33 AM PST In a study I've been reading there was this paragraph: If taller families of plants tend to comprise species with larger effective population sizes , and if a significant proportion of the genomic changes we have measured are deleterious, then a population size effect could explain our results. In this case, selection would be more effective in taller plants, and so slightly deleterious mutations would be fixed less frequently in these lineages. And i don't really understand why that is [link] [comments]  |
| How are deep, narrow boreholes like the Kola Superdeep Borehole dug? Posted: 07 Jan 2020 07:37 AM PST Did it require a 7.5 mile long drill bit? Bonus question: Why don't they install a stirling engine to exploit the free heat at the bottom? [link] [comments]  |
| Posted: 07 Jan 2020 07:17 AM PST It seems like there's an independent convergence between spinosaurus, baryonx, dimetrodon, diloposaurus, etc. Is there anything about this or possibly modern species that could help inform hypotheses? [link] [comments]  |

| Are humans the only creatures that have sex for pleasure? Posted: 07 Jan 2020 12:33 AM PST do other animals just feel like having sex because it feels good or do they only do it to breed? [link] [comments]  |
| Why is the Earth not tidally locked to our Sun? Posted: 06 Jan 2020 11:46 PM PST Seems to me that a lot of the exoplanets we keep finding are tidally locked to their star, but we rotate pretty fast, why is that so? [link] [comments]  |
| How much ocean water is moved worldwide each tidal cycle? Posted: 06 Jan 2020 08:53 PM PST As the gravitational forces of the moon and (lesser) the sun pull upon ocean water huge amounts of water are moved. I'm wondering (and have not been able to find via search) any answer to how many gallons of seawater are moved with every cycle of the tide. Clearly not every tide cycle is the same. Sometimes the sun and moon align such that tides will be much higher or much lower than the mean. Also, in any given tide cycle there will be other factors affecting the amount of water moved, such as winds and major ocean currents. So I would expect any answer to be an estimation and only of a mean tide. [link] [comments]  |
| How do people measure the amount of animals that got killed in the Australian wildfires? Posted: 06 Jan 2020 10:42 PM PST I've seen dozens of news articles, some of which are from credible sources, have stated that about half a billion animals have been killed. Where do they get the numbers? Unless it's all for show or exaggeration? Note: I don't know what to fair this as. Earth Sciences is the closest thing I can think of. [link] [comments]  |
| Posted: 07 Jan 2020 01:26 AM PST There is recent report of a medical negligence in my place, A woman who came with labour pains at a government hospital had undergone cessarian section. After few days she reported severve pain in abdomen, The doctor later diagnosed and found a Surgical cotton wad, used to clean tissue and internal organs is left behind, She latter died without response to treatment. My question is if the Infection and sepis are response by the body to protect from foreign bodies. Why it's fatal in first place? [link] [comments]  |
| How does navigating by Stars work? Posted: 07 Jan 2020 12:30 AM PST I know that in ye old times, a lot of sailors navigated with the stars. How does that work when the stars move in the sky depending on the time of night and the day of the year? I know that the North Star is a thing to help, but how can only one star be the tool for navigating the ocean? And how did people do it in the Southern Hemisphere, without the help of the North Star?

| Is a a sonic boom louder at Mach 3 then at Mach 1? Posted: 06 Jan 2020 06:02 PM PST I was doing a practice test for my high school physics class and this came up? Does anybody know if the boom created at Mach 3 is louder than the one created at Mach 1? [link] [comments]  |
| Does the brain get slightly heavier and bigger the more we learn? Posted: 06 Jan 2020 11:29 PM PST If the addition of new memories and information means more neural connections are created, would that mean the brain (no matter how small) gets bigger due to this, and if so is it noticeable? Is there an observable difference between the brains of those likely to go on to complex learning careers (Doctor, Scientist, Surgeon etc) and those who, well, aren't (me, lol), before they embark on said learning, ie as a child? (not making a case for eugenics here) Is there some truth to the 'big-brained nerd' stereotype? [link] [comments]  |

| Can we find planet like objects that aren't in a solar system? Posted: 06 Jan 2020 06:33 PM PST Going off the definition of a planet as an astronomical body rounded by its own gravity, do we know of any objects like this that aren't part of a solar system? [link] [comments]  |
| Is there a specific point for a chemical where it changes from a gas into plasma? Posted: 06 Jan 2020 10:11 PM PST All chemicals have a melting and boiling points, so I was wondering if there's also a point where a substance turns from a gas to a plasma? [link] [comments]  |
| How does oncotic pressure work? Posted: 06 Jan 2020 09:30 PM PST I get that proteins "pull" water in, but I don't find this trivial. Is it through maximizing hydrogen bonds by making a shell around the protein? Thanks! [link] [comments]  |
| Is skin DNA damage from UV light exposure localized or global? Posted: 06 Jan 2020 09:18 PM PST Is only the tissue in exposed skin effected or does the DNA damage have an impact on all your skin? [link] [comments]  |
