| Do ticks or other blood sucking bugs (mosquitoes, etc) show preference to certain people? Posted: 19 Jun 2018 12:55 PM PDT I'm currently on a hike and my friends have found about 1-3 ticks each while I've found 17 and an hour later another 15. Is there a reason that ticks seem to 'love' me much more than my friends? [link] [comments]  |

| How small can an object be in space and still support an atmosphere? Posted: 20 Jun 2018 03:04 AM PDT I'm assuming it would not only require enough mass but maybe a magnetic field too. Could a large asteroid potentially have a very thin atmosphere? Thanks. [link] [comments]  |
| Posted: 19 Jun 2018 04:56 PM PDT I understand we've found (or found evidence of) ice and liquid water on other planets and moons. Are there any organisms that would likely be able to survive on any of them? Not suggesting we should, but I guess what I'm getting at is, would it be possible to send a population of organisms to other planets and moons, and expect them to thrive and grow? Are there particularly resilient organisms that you'd expect to successfully survive and procreate on Mars or Europa? [link] [comments]  |
| How would superconductor work at all? Posted: 19 Jun 2018 08:02 PM PDT Let say I have a superconducting electromagnet and I want to use it to lift a magnetic object. I apply some voltage to the electromagnet from a battery, because of Ohm's law, I=V/R the current would be infinite and because P=VI the power consumption would be infinite and it would drain the battery's energy in 0 second so I wouldn't even able to life the magnetic object for 1 second. Well, let say the voltage is 0 because the resistance is so low then the current would be 0 and because P=VI the power consumption would be 0 and the electromagnet wouldn't lift the magnetic object at all because there're no energy going into the electromagnet.

| So why do we named galaxies NGC #####? Posted: 20 Jun 2018 05:36 AM PDT I am currently curious as to why we name most galaxies just numbers instead of giving them real names actually? It's honestly superior to know which galaxies are which when they're called the "Sombreo" galaxy or the "Pinwheel" galaxy similar as to how nearby stars have named like Centauri, Bernard's Star, Sirius etc [link] [comments]  |
| Why does the soil rise around constructions? Posted: 20 Jun 2018 04:09 AM PDT When I build a terrance, I always build it a few inches above ground level. Though no matter how well the foundation is laid, the soil still rises above it in a few years. Why does the soil rise above such contructions? [link] [comments]  |
| Does the pressure around a solid have an effet on its vibrations ? Posted: 20 Jun 2018 03:57 AM PDT For example, if I were to hit a drum on earth and in space, would there be any difference in the vibrations of the drum ? Of course the sound wouldn't be heard in space because of the vacuum-like environment, but would the object still vibrate in the same way (frequency, amplitude, etc) ? [link] [comments]  |

| Why can’t we harness the Casimir effect as an energy source? Posted: 19 Jun 2018 11:12 AM PDT Sixty Symbols- Casimir Effect and Black Holes From what I understand it would not ever produce too much energy even if harnessed. Let me be clear I am a chemistry undergrad senior with only basic knowledge of physics, so please excuse my naïvety; but would it be possible to use plates with some sort of piezoelectric properties to convert the pressure differential between the inter-plate space and outer-plate space into an electric charge that could be exported to a battery? Or am I misunderstanding the kind of energy differential between those plates? The smart-ass sci-fi buff in me wants this to be a viable theory, but I've read countless times that there's absolutely no way it could work; and i've always found the explanations lacking. Can anyone explain this one to me? [link] [comments]  |
| Posted: 19 Jun 2018 07:24 AM PDT Hey r/askscience, Today my mom put some flowers in a bowl with water and as i watched them closing i started to wonder what actually causes the movements of plants. With movement i mean for example the opening and closing of the blossom and the sunflower orientating itself towards the sun How do they do that? What kind of mechanism does that?

| Is there any way to tell foreshocks from the main quake? Posted: 19 Jun 2018 07:23 AM PDT Will be travelling to Osaka next week. Is there any way to tell whether an earthquake is a foreshock or the main quake until weeks/months after it happened? What's the probability the 6.1 Osaka quake was the main quake? (If possible to tell) Thanks! [link] [comments]  |
| Why do mosquito bites cause a lump on your skin that itches? Posted: 19 Jun 2018 11:22 AM PDT Basically what the title is asking. Is it some kind of allergic reaction that all humans are allergic to? [link] [comments]  |

| How does room temperature salt added to ice lower its temperature? Posted: 19 Jun 2018 07:35 AM PDT I can't understand how ice, which is 0 degrees, can LOSE temperature when room temperature salt is added to it. On a fundamental level it doesn't make sense. There are so many questions. I've read that the process of melting absorbs energy, but that just makes me think then surely it can't melt. If freezing releases energy and melting absorbs it, does that mean the process interferes with itself? Water freezes, which releases energy, which should melt it again. If the temperature of the ice drops, where's that energy gone? I mean it has to still be there. If it still has the same energy, why is the temperature less? Temperature is just particle movement, right? So temperature dropping means the particles are moving more slowly. I guess salt makes the molecules in the ice both detach from each other (melting the ice) AND makes them move more slowly than they were when they were attached. Is that accurate? I've tried reading explanations but they just say a) salt lowers the melting point so it melts and b) melting absorbs energy so it gets colder. But I still don't feel like I understand.
