| How are the standards for sufficient Vitamin/Mineral concentration in humans fixed? Posted: 14 Apr 2019 07:40 AM PDT I recently read an article about the debate on standard for sufficient Vitamin D levels, and 2 groups come up with distinct ratings for the normal levels. With standard statistical techniques shouldn't there be no disagreement about these things? (like mean in a population?). But say we got the population means for 2 different geographical areas, or maybe 2 different ethnic groups, then there is a chance they might be different. So how can we tell if this difference indicates a deficiency ( or conversely overconcentration) in one, or it is just characteristic for that group? [link] [comments]  |
| Do blind people have more trouble creating a stable sleep/wake rhythm? Posted: 14 Apr 2019 07:36 AM PDT Hi r/askscience, I am a student Biomedical Sciences with a very (in my opinion too) small background in neurosciences. I know that people become sleepy because melatonin gets released at certain times through the biological circadian rhythm and due to a lack of light that hits the eye. Knowing that the presence of light heavily influences the melatonin release and knowing that the human rhythm is approx 24,5h, I was wondering whether blind people have more trouble acquiring a 'regular' circadian rhythm when compared to a person that can see properly. Cheers! Edit: please forgive me for any spelling or grammatical errors. I am on mobile and English is not my first language. [link] [comments]  |

| How does interaction with a Higgs Boson particle indicate mass? Posted: 14 Apr 2019 05:19 AM PDT Title really. I think I'm conceptualising this correctly, and it says that a particles mass depends on how much it interacts with a Higgs Boson, like a top quark has a high mass because it interacts with it a lot, but a photon doesn't interact at all, so it has no mass. So how does interaction with the Higgs field or the Higgs Boson particles indicate mass? Thanks. [link] [comments]  |

| Overall, is increased desertification a positive or negative feedback loop for climate change? Posted: 14 Apr 2019 03:20 AM PDT I know deserts reflect more sunlight than forests, but forests absorb CO2. What is the net impact of those effects? [link] [comments]  |
| Is LIDAR light visible to any known animal species? Posted: 13 Apr 2019 09:55 AM PDT The more common this technology becomes, the more likely it is that urban and suburban environments will be awash with the light from these systems. Extensive research has been performed on radio frequency sensitivity within nature, as well as the effects of acoustic sensors in marine environments, however I have yet to see any research discussing/exploring this topic of LASER within nature. Short or long answers welcome and as always, citations are preferred where possible. [link] [comments]  |

| Birth control stats, how are they measured? Posted: 13 Apr 2019 04:56 AM PDT I work part time in an ob/gyn clinic and it seems like the most effective method has like 1/2000 chance of getting pregnant. So if a person (female) had sex 2000 times (mind you I'm a redditor, so I'll be lucky to get there in a lifetime, so this person won't be me) chances are they would end up pregnant. I guess I'm just not sure how these stats come about and what they mean. And they are not super reassuring to me. I also assume the companies also don't want to say their method is 100% effective as well. And I've seen a few IUDs inserted incorrectly so human error is also a concern. [link] [comments]  |
