| How do animals like squirrels get water when there are no nearby rivers, streams or ponds? Posted: 16 Nov 2016 06:14 PM PST I live in a place where there are squirrels, rabbits and other small animals almost everywhere but the nearest source of water is miles away. How do animals such as these get their water? [link] [comments]  |

| Posted: 16 Nov 2016 06:28 PM PST I've always wondered this. Essentially, running the A/C costs energy, so it's worse for the environment than just having windows open. But if you're going fast, the windows being open adds a lot of drag, so you have to spend more energy to maintain the same speed than if they were closed. What speed would I need to go for the energy "benefit" of not running A/C be equal to the energy loss of that drag? This obviously depends on car model, temperature difference, wind, air pressure... I'm more interested in order-of-magnitude guesses. Is this achievable with a standard sedan? Are cars designed so efficiently that I'd need to break the sound barrier to get close?

| Are transparent objects like glass non-transparent for animals who have different visible spectrums? Posted: 17 Nov 2016 05:37 AM PST Similarly to the question above, let's say an animal couldn't see our visible range of "blue". Would blue be transparent for them? [link] [comments]  |

| Why aren't we able to keep isolated brains alive? Posted: 16 Nov 2016 07:31 PM PST So, I was on the Wikipedia page for brains that have been separated from the body and kept alive in vitro, and it's made me wonder, why aren't we able to keep the brain alive for more than a few days?

| Posted: 17 Nov 2016 04:34 AM PST I'm looking at cobalt as a catalyst and need to know specifically what is about Co in mixed oxides that makes it good for desulphurisation, for the production of terephthalic acid (TPA) and di-methylterephthalate (DMT) as well as reduced cobalt in hydroformylation. I'm assuming it's something to do with its transitory nature but don't know much more than that and am having a hard time finding papers that explain its efficacy instead of jumping into the hard catalysis science. Cheers. [link] [comments]  |
| How does a mother's body "know" when to start and stop producing breastmilk? Posted: 17 Nov 2016 08:05 AM PST For instance, is breastmilk still produced when a baby is born prematurely? What about if the baby is stillborn/miscarried very late? I know some mothers breastfeed their children for several years, is there any point at which the body simply stops the supply of milk? Thanks! [link] [comments]  |

| Will pre-blended gases separate under pressure? Posted: 17 Nov 2016 07:42 AM PST I work in the beer world, installing draft systems. Certain systems call for different setups, but they often need a blend of gases (co2 and n2) in varying mixes to answer the needs of the system. Most often this calls for a gas blender that blends the two gases actively from a pure co2 tank and a pure n2 tank. Occasionally, the setup calls for just using gas that is pre blended by the gas distributor in one tank. In this particular case, the blend is 75% n2, 25% co2. Would the gases potentially separate over time in the tank, rendering the blend ineffective? And if it's not too much to ask, what is the science behind it? Thanks for any insight, you guys are the best. [link] [comments]  |

| Posted: 17 Nov 2016 07:12 AM PST Specifically, how can they be used in algorithmic production of music? Also, what is the difference between discrete and continuous chains? [link] [comments]  |
| Posted: 17 Nov 2016 07:12 AM PST In the backstory of Danny Boyle's SciFi film Sunshine (2007), it is explained that a Q-ball enters and is caught in the Earth's Sun and is the reason why Sun is dying. What is a Q-ball and how is it capable of killing the sun? [link] [comments]  |
| How do ions in a solution conduct electricity? Posted: 17 Nov 2016 06:47 AM PST I'm aware that ions conduct electricity, however, most of the sources I've seen give me only a really basic explanation of why this happens. Does anyone have a really in-depth way of explaining this? [link] [comments]  |

| How is colored PTFE (teflon) made? Does it change the properties? Posted: 16 Nov 2016 08:39 PM PST I see all sorts of colors of teflon available from manufacturers claiming that coloring doesn't affect the properties of it. My basic knowledge of PTFE has me thinking that it's impossible to dye. My best guess is some compound is mixed in before it's sintered. Does this really have an insignificant affect on the properties of the end product, specifically its friction? [link] [comments]  |

| Do all gases expand at the same rate when heated? Posted: 16 Nov 2016 07:28 PM PST Was reading an equation dealing with air recently "Standard cubic foot(SCF) = CF x (Pact/Pstd) x (Tstd/Tact)" and was wondering if this is applicable to all gases or if there is a constant for different gase that needs to be used for it to be accurate. Example, assume P remains constant: If CO2 is heated from 20°C to 100°C it expands by "x". Do all other gases also expand by "x" when heated from 20°C to 100°C? If so, or if not, why?

| Posted: 17 Nov 2016 04:08 AM PST So I got a tetanus shot in one arm and a flu shot in the other. I asked the nurse if the immune response was different if two vaccines were administered instead of one. She said no, because they were dead cultures. Is there a "bandwidth" to what the immune system can respond to. Surely if I had 100 vaccinations in a minute there would be repercussions! (Yes vaccinations work, this is a question about how they work together) [link] [comments]  |
