If telomers get shorter with every split of a cell, doesn't this mean we can pretty accurately calculate when someone will die of old age? |

| Posted: 08 Aug 2017 12:04 PM PDT Organizations like Transparency International publish corruption data from all over the world. How do they get their data? It's obviously a crime that is attempted to be hidden. [link] [comments]  |
| What determines whether ancient plant/animal material turns into oil vs coal? Posted: 09 Aug 2017 06:17 AM PDT Also, how much coal/oil would a house cat sized animal produce and/or a plant with the mass of a house cat? [link] [comments]  |
| Why aren't pixels made up of 'RYB' LEDs instead of RGB ones? Posted: 08 Aug 2017 01:59 PM PDT Was wondering that since the 3 primary colours are red, yellow and blue would it not make more sense in some applications for yellow LEDs to be used instead of green LEDs for pixel based displays.

| Posted: 09 Aug 2017 03:52 AM PDT Or, to rephrase that, let's suppose we could access news from a parallel universe where Suharto, Marcos and Mugabe never came to power and leaders of integrity had been in place instead ... how would the economies of the alternate versions of those countries differ from what we know?

| Why do some people have an allergic reaction to pollen, while others do not? Posted: 08 Aug 2017 05:16 PM PDT As an added question, why are allergic reactions to pollen so different from allergic reactions to food? [link] [comments]  |
| How many particles in the universe? Posted: 08 Aug 2017 02:26 PM PDT So people always say there's like 1082 particles in the universe or something like that. But how many particles are estimated to be in the actual universe? I know we don't know the size of the universe but assuming it's finite and we know what the expansion rate is would it be possible to estimate it? Or would it just be the same as the observable universe? [link] [comments]  |

| Posted: 08 Aug 2017 07:30 PM PDT Intuitively, I would think that the material that is currently condensing as a second protostar would be blown away by the new star's solar wind. [link] [comments]  |
| When glaciers scraped away so much soil and other material during the Ice Ages, where did it go? Posted: 08 Aug 2017 07:29 PM PDT The soil in most of Northern Europe and much of North America is less than 10,000 years old due to glaciers scraping away so much soil compared to areas that didn't have glaciers in the Ice Ages. Glaciers also flattened the land. I used to live in the US in Indiana. Over there the northern half of the state is flat while the southern half has a lot of hills because the northern half was scraped flat by glaciers. Where did all of this material go?

| Why is gravity referred to as a "force"? Posted: 08 Aug 2017 08:46 PM PDT I'm not a physicist, and my formal physics education ended my freshman year in college. That said, I still have to wonder why people refer to gravity as a "force"? I have been under the impression - at least since I started reading about relativity decades ago - that gravity wasn't a "force" (like electromagnetism and the other two quantum forces) so much as an emergent property of the curvature of spacetime. That's why it's been so difficult to reconcile quantum theory and relativity: we're talking about apples and oranges. The quantum forces are described as fields and seem to exist superimposed (somehow) on the larger "canvas" of curved spacetime. Gravity can certainly affect the quantum forces - light bends in the presence of a strong spacetime curvature - but the quantum forces seem to have no effect whatsoever on gravity. Forgive me if my understanding of physics is faulty but every time I read an article that refers to the "force of gravity" it makes me think they don't know what they're talking about.

| [Physics] How does dew form? And also, what exactly does the dew point mean? Posted: 09 Aug 2017 05:03 AM PDT I was up early this morning and was looking around my yard. And also looking at the few, and wondering how it formed, and what the dew point has to do with it. My best idea is that condensation comes down overnight and makes dew stick to everything? At least until the sun comes and "melts it off"? [link] [comments]  |

| How do you determine the height of an island? Posted: 08 Aug 2017 03:34 PM PDT If I am on an island and push a 7 ft. boulder to it's highest point, did I just raise it's height by 7 feet? What determines how tall it is? [link] [comments]  |
| Are there certain ethnic grouos that tend to have a higher number of Neanderthal gene variants? Posted: 08 Aug 2017 06:45 PM PDT A few of my family members and I recently took the 23&Me genealogy test which tells you how many Neanderthal gene variants you have. My grandfather, who had a higher percentage of Southern European ancestry had a much lower number of Neanderthal genes than my grandmother, and father (not the son of thse two people, they are my maternal grandparents) who have a much higher percentage of Northern/Northwestern European ancestry. This led me to think that perhaps Neanderthal genes are more prevalent in North/Northwest Europe. Is there any validity to my thought? If not, is there any observed tendency that Neanderthal gene variants have in certain population? [link] [comments]  |
