| How do marsupials clean their pouches? Do they smell terrible? Posted: 27 Jan 2019 06:05 PM PST I was thinking about how disgusting a human pouch would be. Can someone elaborate? [link] [comments]  |
| How do surgeons and doctors calculate the risk of a surgery? Posted: 28 Jan 2019 07:14 AM PST I've been wondering this. For say, a spinal surgery has 40% chance of success, how is it measured or is it more intuition? [link] [comments]  |

| How much caffeine will it take too be lethal? Posted: 28 Jan 2019 05:41 AM PST This is the question that I have been thinking ever since I try to drink coffee (almost) everyday. I'm just wondering, how many caffeine does it took to be a dangerous chemical? (Mods: no this is not a personal question/medical advice, It's just what I think when I'm drinking coffee) [link] [comments]  |
| How were diffraction patterns for crystallography resolved before computers? Posted: 28 Jan 2019 03:33 AM PST Was it done using pencil and paper calculations that translated into structures or did the patterns more directly correspond to certain structures? Edit: clarified in post body [link] [comments]  |
| Can manufacturers use high pressures to melt elements quicker and more cost effectively? Posted: 28 Jan 2019 12:50 AM PST Hey all! My understanding of basic chemistry/physics is that at higher pressures, matter is forced closer together, which makes it heat easier because the molecules have less space to move ; I learned the other day that tungsten and platinum have very very high melting points, and wondered about the prospect of a company performing all of their manufacturing inside a pressure chamber to save on gas/electricity costs of running furnaces up to 10,000 Fahrenheit for tungsten and 3000~ for iron and steel. Is there something I'm missing about this? Surely it would be more cost effective to effectively "lower" the temperature requirements of melting metals by a certain percentage (say, 25%), than it would be to keep a large chamber running at 2,5,10, or 25 times atmospheric pressure. Thanks! [link] [comments]  |
| Why do some fruits contain high levels of proteolytic enzymes? Posted: 27 Jan 2019 08:41 PM PST E.g. pineapples with bromelain, papain in papayas, ficain in figs. I have read somewhere that proteases are sometimes required for protein synthesis/activation, but why would some fruits have such high levels compared to others? [link] [comments]  |
| Posted: 28 Jan 2019 07:03 AM PST While the cold blood of insects and arachnids makes them more susceptible to fungal infections than warm blooded animals, this does not explain why reptiles and other cold-blooded creatures are not targeted by "body controlling" organisms like the Cordyceps genus of fungi.

| How do they measure the energy of ocean waves? Posted: 28 Jan 2019 06:18 AM PST When they say these waves create the same amount of energy as 10000 atomic bombs everyday, how did they get this number? [link] [comments]  |
| How does a potassium chloride injection stop the heart? Posted: 27 Jan 2019 04:26 PM PST I have very basic knowledge in neuroscience, so an explanation in layman's terms would be great. [link] [comments]  |

| How do normal bodily functions work in zero gravity? Posted: 27 Jan 2019 04:23 PM PST E.g. pumping blood, digestion, don't these processes rely on gravity? [link] [comments]  |
| What causes the force that results from the Pauli exclusion principle? Posted: 27 Jan 2019 09:43 AM PST I was reading about white dwarf stars in Stephen Hawking's "Brief History of Time", and he states that the only thing preventing a white dwarf from collapsing into a black hole is the repulsive force provided by the Pauli exclusion principle, but for stars with masses past the Chandrasekhar limit, this force is eventually overcome by gravity. My question is where does this force come from (does it have a force carrier) and can it be explained in terms of the four elementary forces? Also as an aside, how can the exclusion principle be "overcome" by gravity? Does the law simply break down with forces that large? [link] [comments]  |
