| How do the 420 underwater cables that transmit all of the internet information work? Posted: 16 Aug 2019 03:43 PM PDT I read that they're no wider than a can of cola. How is it possible that they send all of that information on that relatively small amount of wire? Do the signals transmit in one direction only or in both directions? Why is there no interference between signals being sent? Any other information would also be greatly appreciated. [link] [comments]  |

| What's the purpose of the eigth reaction of glycolysis? Posted: 17 Aug 2019 04:15 AM PDT I'm talking about the reaction from 3-phosphoglycerate to 2-phosphoglycerate, catalysed by phosphoglycerate mutase. Since the phosphate group will ned to be removed to make ATP, why bother moving it? [link] [comments]  |

| How do electromagnetic waves sustain themselves in vacum? Posted: 16 Aug 2019 10:19 PM PDT I do understand that each "half" is perpendicular to each other but how does that help it keep traveling and do they lose energy by doing so? (Like, do they go on for infinity or travel through a specific distance/time) [link] [comments]  |
| Are tattoos carcinogenic and/or do they have longterm adverse health risks? Posted: 16 Aug 2019 11:51 AM PDT I'm not talking about short-term risks that seem to be well-documented, such as allergic reactions or infections from tattoo ink, but rather longterm risks associated with toxicity/cancer such as heavy metals, phthalates, polycyclic aromatic hydrocarbons (PAHs), N-nitrosamines, and "nano-particles" accumulating in the lymph nodes or traveling in the bloodstream. The lymph nodes of tattooed people are often dyed. For example if someone were to get a tattoo with black ink that contains no heavy metals, but is made from carbon black 7, how dangerous is from this a scientific perspective? I read that carbon black is carcinogenic, and that it breaks into "nano-particles" very easily. If these nano particles can travel the lymph nodes of tattooed people, does that mean they're in the bloodstream and can travel to my brain as well? And if carbon black is apparently carcinogenic, by putting in my body are we talking about a 2x lifetime risk for cancer (perhaps not worth worrying about), or a 20x risk (probably a bad idea)? A lot of layman dismiss these concerns, so I would like the blunt science on it particularly on how it pertains to carbon-based black tattoo ink. [link] [comments]  |

| What causes gas escape from holes in shallow carbonate hardgrounds/reefs? Posted: 16 Aug 2019 08:58 PM PDT I was snorkelling in a fairly dead reef (mainly just carbonate hardground, there was little living coral there) when I noticed a number of small holes on the hardground (c. 1cm across) with a fairly steady stream of bubbles escaping (fluxes probably on the order of 1-10 cm3 s-1 per hole). There were quite a number of these holes, although they seemed concentrated in a specific area. This was during the ebb tide, with waves around 1m high. The hardground would probably have been exposed or in very shallow water during the low tide. Does anybody have any idea what these might have been? The amount of gas being released seems to high to me for it to be biological, but I could well be wrong. I was wondering whether it could be related to the flushing of trapped air from voids within the hardground, but the stream of bubbles seemed too steady for that. [link] [comments]  |
| Quantum mechanics explanation of the relativistic effects on heavy elements? Posted: 16 Aug 2019 08:21 PM PDT Recently I found out that on heavy elements, relativistic effects can change the properties of an element due increased mass of the electron. However, all the explanation that I've found on the internet explains this phenomenon using the velocity of the electron. From my understand of the electron, electrons don't really "move" in the atom and instead exist as a probability cloud. If this is the case, how can we explain the relativistic effects using a non-Bohr model? I am a non-native English speaking high school student so please explain this in an easy to understand manner.(equations are fine as long as it's at an understandable level) Also, does an electron have momentum?(If so can we say that it has velocity?) This is a question that I had for a long time and thought that I'd ask it here since it's kind of related. [link] [comments]  |

| Can a hemophilia carrier be diagnosed through a karyotype? Posted: 16 Aug 2019 12:33 PM PDT Or is the karyotype only meant for identifying numerical chromosomal abnormalities? [link] [comments]  |

| Can entangled qubits be stored? Posted: 16 Aug 2019 11:38 AM PDT My question is about quantum teleportation and saving the entangled qubits for later communication. I understand that there isn't any faster than light ways to communicate instantly on demand using qubits as classical means must be used to share the measured state of one of the pair (or triplet, etc). However, what if there was a way to save up (say magnetically trapped, supercooled, something like this) qubits and then use them when needed. Why couldn't this be harnessed into something like subspace communication in Star Trek? As long as a starship brought along enough entangled qubits there could be instantaneous communication back to mission control. [link] [comments]  |
