- Certain radiation can be blocked with different thicknesses of matter; is there an equivalent that can be used to block a magnetic field?
- if the earths core is molten, how does it generate a magnetic field around the earth. Aren't temperatures high enough to make metal molten enough to prevent it from being magnetic. What am I missing? I'm an Artist not a scientist.
- What career choice makes the highest percentage of people happiest?
- [physics] If the earth wasn't spinning would we feel the gravity more because of the lack of centrifugal forces?
- How do scientists do really thin slices?
- How the band theory can explain the electron mobility that, for example, through a electric potential difference can generate electric current?
- They say that all blue eyed humans have a common ancestor 7-10 thousand years ago. What about blue eyed dogs, horses or other animals? Is the mutation similar in all species? What would cause such a similar mutation among such varied species?
- In a scenario where human life is exposed to long term (millions of years) reduction of oxygen (like in mountain tops), would the human body adapt do this change?
- Did lemons and oranges evolve from the same source? what about grapefruits and other citrus? did this parent plant have a name?
- If organic compounds are the most important for creating and sustaining life, why do we still continue to classify water as inorganic?
- Why can a single individual react so differently to drugs in the same family (i.e. Xanax vs Ativan, both benzodiazepines)? And why do different individuals experience just as much variance between drugs, but not the same experiences on the same drugs as other individuals?
- Why is isopropyl alcohol considered toxic/dangerous, but ethanol is not, despite similar ld50 values?
- Does sound travel extremely well through a neutron star?
- At extreme temperatures, do photons behave differently?
- Is true wireless charging possible?
- Do people retain information better depending on the color of light source they're under?
- Is it possible to figure out the stage of Fall a region is in by doing a spectral analysis from a satellite?
- Can something be 1.5 plank lengths long?

| How do scientists do really thin slices? Posted: 09 Sep 2016 06:05 AM PDT I'm impressed by cooks on TV that cut really fine slices of carrots or something. But when you think about it, scientists do much finer cuts than that, although I'm sure you don't use a kitchen knife. So for example in biology, you put something on a glass that you can look at in a microscope... But how do you get it there without it breaking apart? What do you use for cutting? How do you know how thick/thin to cut? Do you have to like freeze it first or process it somehow to get it there? [link] [comments]  |

| Posted: 09 Sep 2016 06:04 AM PDT So this just occurred to me after hearing the news of NASA's Osiris-Rex mission to study the Bennu asteroid. If my understanding is correct this NASA mission is trying to find out more about how our solar system formed by analysing the amount of Carbon (organic compound) that it is made from. The correspondent reporting on the mission says
I then did some digging and found a Cliff Notes page on the role organic compounds play in the chemical basis for life It states
There's no mention of the important role water plays in life processes. So my question is If organic compounds (ones that contain Carbon) are the most important for creating and sustaining life why do we still continue to classify water as an inorganic compound (even though it doesn't contain carbon)? We make exceptions for some compounds (i.e. some carbonic compounds are classified as inorganic) so why can't we do the same for H2O? [link] [comments]  |
| Posted: 08 Sep 2016 08:57 AM PDT I hope I was coherent, but I'll give some examples to clarify. Individuals A and B have been prescribed both Xanax and Ativan. (A) reports that Xanax has had a stronger effect on their anxiety, while Ativan is too mild and ineffective. (B) reports that Ativan is stronger and more effective, while his Xanax is too mild. Assuming similar BMI, same sex, and same treatment method, why are the experiences so different? [link] [comments]  |
| Posted: 08 Sep 2016 08:46 AM PDT So I've seen similar posts but none seem to explain to the level that I'm looking for. The way I've read Isopropyl metabolism ->acetone -> lactic acid -> pyruvate -> acetyl coA Whereas ethanol metabolism -> Acetylaldehyde -> acetate -> water+ CO2 Acetone is normally found as a product beta oxidation of fatty acids. The body has a distinct process for handling this and long term studies on ketogenic diets don't necessarily point to them being damaging. The only things I can think of are: -Isopropyl alcohol is more potent, and thus people who don't know better drink more of it, and end up dead. -The additives to make it taste bad are actually toxic. -Isopropyl metabolism exhausts the body's supply of co-enzymes, and you are stuck with a lot of acetone. The ld50 of isopropyl is about 5g/kg and ethanol is about 7g/kg, so they're pretty similar. Edit: Update: Found this little paper here: https://toxnet.nlm.nih.gov/cgi-bin/sis/search/a?dbs+hsdb:@term+@DOCNO+116 While the majority of it is converted to acetone, some of it is converted to formate, the anion of formic acid. Formic acid is what causes blindness in methanol consumption. [link] [comments]  |
| Does sound travel extremely well through a neutron star? Posted: 08 Sep 2016 11:45 AM PDT As far as I'm aware, the denser a substance is, the better sound travels through it. That'd be why you can hear sounds far away on a clear winter day or just before a rain storm when the atmosphere has high humidity. Would the same apply to a neutron star, could you hear sounds extremely far away through the material a neutron star is made of, in theory? Of course there are other things to take into consideration, but if you're strictly thinking about how well sound transmits through the extremely dense neutron star, would it be true that the sound can travel very far and very quickly and efficiently?

| At extreme temperatures, do photons behave differently? Posted: 08 Sep 2016 11:40 PM PDT Would a photon at 0K behave differently than one at 300K? What about a photon at 9999999999K? Are there any anomalies as photons approach these temperatures? Since we are unable to actually create these scenarios [but can get pretty darn close], I understand the question may be too difficult to answer. [link] [comments]  |
| Is true wireless charging possible? Posted: 08 Sep 2016 04:35 PM PDT They need wires and only work when the phone is almost touching them. Why? How much energy would be needed to charge a smartphone from 5 meters away? [link] [comments]  |
| Do people retain information better depending on the color of light source they're under? Posted: 08 Sep 2016 05:24 PM PDT |
| Posted: 08 Sep 2016 01:34 PM PDT The spectral analysis would be checking leaf color change over time over a large swath of land. In theory, over time there would be a general shift (different per region) from green to a Fall color. [link] [comments]  |
| Can something be 1.5 plank lengths long? Posted: 08 Sep 2016 07:52 PM PDT Nothing can be shorter than a plank length, but is length/distance a discrete thing? [link] [comments]  |
| Can the blue land crab (cardisoma guanhumi) breathe underwater? Posted: 08 Sep 2016 07:46 AM PDT The blue land crab is described online as being semi-terrestrial, is said to be capable of living in both terrestrial and marine environments, and is said to return to water to drink and to breed. On one website, they're described as needing water to breathe. All that considered, I need a definitive answer to these questions: Would one of them (apparently a juvenile or young adult) survive if released into water? Can this species of land crab breathe underwater? Is it capable of swimming? [link] [comments]  |
