| Does a handicapped caterpillar turn into a handicapped butterfly? Posted: 27 Nov 2015 09:57 AM PST For example: when a caterpillar drops and damages one of it's legs, does the damage carries on to the butterfly's leg? [link] [521 comments]  |
| Why do wind turbines only have 3 blades? Posted: 28 Nov 2015 06:23 AM PST It seems to me that if they had 4 or maybe more, then they could harness more energy from the wind and thus generate more electricity. Clearly not though, so I wonder why? [link] [23 comments]  |
| Why does anxiety often manifest in minor self-destructive behavior? Posted: 27 Nov 2015 08:16 PM PST For example: Nail biting, plucking hairs, peeling lips with teeth, picking at scabs, scratching raw, etc. [link] [10 comments]  |
| Why do whales die when they're beached too long? What is it that kills them? Posted: 27 Nov 2015 06:44 AM PST I have always wondered this. Edit: Thank you for your responses, everyone! [link] [204 comments]  |
| Posted: 27 Nov 2015 12:33 PM PST In light of the final antibiotic having resistant bacteria emerging, could we use CRISPR as a last ditch effort to save someone? If we removed the gene that caused resistance and then used the antibiotic would the antibiotic be able to kill the bacteria? Is anyone trying something like this on animals, or is it just a silly idea for some reason that I wouldn't be able to think of? [link] [28 comments]  |
| Posted: 28 Nov 2015 03:43 AM PST Since the cold part is vented outside (and we don't care about how cold the outside gets), would conservation of energy mean that we've generated more thermal energy inside the home? Compared to an electric heater that is just converting 100% into thermal energy? [link] [2 comments]  |
| Posted: 27 Nov 2015 08:45 AM PST It occurred to me while reading a paper that I have no idea how this is actually done in practice and how effective these measures are at helping researchers come to more useful conclusions. Any info appreciated. [link] [12 comments]  |
| Posted: 27 Nov 2015 07:40 PM PST I'm thinking about a lake like Lake Erie. Is the elevation of the water at the western Ohio end substantially higher than the elevation of the water at the eastern New York end? [link] [28 comments]  |
| How does one define a staight line? Posted: 27 Nov 2015 07:12 AM PST I was taught that the definition of a straight line is the shortest distance between two points. What happens if these points are infinitely far apart? I assume that this is basically some kind of phallacy/ paradox type thing but yeah, lemme know please! [link] [36 comments]  |
| What is the Riemann Zeta Function, and what's the point of it? Posted: 27 Nov 2015 06:18 PM PST I've read into this thing via wikipedia and wolfram mathematica, and I still have no idea what it's trying to do. [link] [3 comments]  |
| How come wet clothing dries pretty quickly, but water in a cup doesn't just evaporate away? Posted: 27 Nov 2015 10:23 AM PST Say you spill an entire cup of water on your shirt. That will dry up relatively quickly (say, a few hours or so). But if instead you just leave that cup of water sitting open, the water won't evaporate in even many days. Why? [link] [13 comments]  |

| How do armadillos transmit leprosy to humans? Posted: 27 Nov 2015 10:46 AM PST Are Armadillos the only animal carriers of leprosy or are they the only animals that can give leprosy to humans? If so, why only armadillos? Read somewhere that they enable the infection to survive in the due to their lower body temperatures. However I don't understand how or why only armadillos can give the infection to humans. [link] [3 comments]  |
| Is earth's electric potential growing or decreasing? Posted: 27 Nov 2015 07:32 AM PST So I've learned recently that V = q/C Now, I understand that when you ground something because the huge difference in capacity all of the charges will pass down to earth. When you ground something earth's potential doesn't really change because everything you ground is just a part of earth. However, considering earth is not a closed environment and interacts with solar storms, asteroids and other outside effects, is it's electric potential growing or decreasing? [link] [4 comments]  |
| How is ounce (oz), a unit of mass, sometimes converted freely to volume? Posted: 27 Nov 2015 07:42 PM PST Example, you have 24 oz cups, and such. I understand that if you know the density of said liquid, you can use that to convert the said mass to volume. however, they convert freely using soda in said cup to volume. so here im assuming that the assumption is made that the density of soda is the same to water (which is probably close enough) however, isnt it still wrong to use this general measurement for cup sizes seeing has how other liquids can be put in it?

| What are these weird byproducts of electolysis? Posted: 27 Nov 2015 08:47 AM PST I dissolved salt into some water, connected 3 9-volt batteries to some copper wire and collected the hydrogen in a shot glass. But the water began to smell like a pool(chlorine) and there was teal sludge an red stuff too. What is that stuff? here is a pic: https://imgur.com/KFeGHo1 [link] [9 comments]  |
