| What methods are used to trace the origin of a new virus? Posted: 27 Jan 2020 05:30 AM PST What sort of methods of investigation/experimentation are used to determine/trace the origin of a newly discovered virus? That is to say, When a new virus is discovered, how do we find out where it first appeared? [link] [comments]  |
| How deep below sea level could a canyon theoretically get? Posted: 27 Jan 2020 03:42 AM PST Would it get too unstable at some point and collapse in on itself? [link] [comments]  |

| Do stars that are about to go supernova cause any visual cues before it actually happens? Posted: 27 Jan 2020 02:32 AM PST Hello, as title says do stars that are about to go supernova create any actual visual cues in them when they are getting close to going supernova like lets say when they enter into iron fusion phase (or any other phases such as silicon) or area about to enter into it and yes im aware that stars cannot fuse iron. Besides them dimming would observer notice any noticable difference in their orbit in it such as sudden colour change, more violent shedding of their outer layers or are visual cues too slow to rise from core that they do not have time to make it into surface before star goes supernova? Would i notice something different in orbit rather than light-years away such as case in betelgeuse dimming? What about sudden tempature changes or any other noticable differences before supernova or moments before it? Would i really see star rupture in half if i could see it in slow motion enough? Thank you in advance for answers. [link] [comments]  |
| Does DNA vary in length, or is it the same in every case? Posted: 27 Jan 2020 05:01 AM PST Are simple creatures just working with shorter DNA, and thus can't be as complex as humans? Or if DNA is always the same length, how does a simpler creatures DNA compare to ours? Is there just a lot of 'blank space?' (parts that don't really add anything) [link] [comments]  |

| How do twisted pair wires reduce electromagnetic interference? Posted: 26 Jan 2020 03:59 PM PST I've scoured the web and I just keep finding sources that elaborate what a twisted pair is or their history. I cannot find anything that explains how twisting 2 wires around each other insulates them and prevents magnetic fields affecting them. Are they creating their own protective magnetic field? What is happening? Edit: what a great turnout! Seriously thank you everyone for the replies. Everyone explained it a little differently, but in the end it helped visualize it for me.

| Will the Sun's gravitational pull on Earth change as it expands? Posted: 26 Jan 2020 01:34 PM PST I was thinking about the Sun's expansion at the end of it's life- as it expands a portion of it's matter will become ever closer to us, but on the opposite side of the sun from us matter will be getting farther away. Will the change in distance of matter on both sides cancel itself out? Will the Earth experience a greater pull, sucking it in before the expansion would have consumed it? Is this a completely misguided question? Thanks in advance. Edit: I did Google the question before asking, but none of the answers addressed the matter / mass getting closer to Earth, which to me would change the gravitational force. The answers simply stated that gravity wouldn't change. The volume is increasing, but not mass. [link] [comments]  |
| What determines a virus' incubation period? Posted: 26 Jan 2020 06:14 PM PST What would stop a virus from taking longer to incubate like a week or more? What factors are at at play and why are most viruses in that 1 to 3 day range or so? Is it possible for a virus to incubate longer? What do you think would be the maximum incubation period possible?

| Posted: 26 Jan 2020 09:31 PM PST Earth cools down gradually as it ages. The first eon was so hot there was no solid surface. I'm curious about how quickly volcanism would slow down, if at all. Would it do so incrementally or continuously? By "slow down" I mean less volcanoes, less eruptions from volcanoes, smaller eruptions, or some combination of those three. [link] [comments]  |

| When did the term "climate change" come into use? Posted: 26 Jan 2020 11:39 AM PST When I was a kid, 80s and 90s, the term "global warming" was commonly used to describe our ecological influence. Then sometime in the early 2000s the term "climate change" started being used everywhere as the common verbage for our ecological influence. When did "climate change" come into use by the scientific community? What's the story of "climate change" being funneled down to us plebs? If it wasn't scientists who invented the term "climate change", who did? Why? Thanks [link] [comments]  |
| if plankton produce oxygen, where does the carbon go? Posted: 26 Jan 2020 01:39 PM PST with regular plants, carbon goes to making the plant - what does plankton do with the carbon as it produces oxygen? [link] [comments]  |
| Where does the gas go when you "inner-fart"? Posted: 26 Jan 2020 01:25 PM PST |

| Do green bell peppers photosynthesize, or does their green color come from something else? Posted: 26 Jan 2020 01:55 PM PST Normally I don't think of a plant doing photosynthesis on its fruits, but today I was chopping a green pepper and got curious about whether it was possible. Thanks!

| Is carbonated water as hydrating as flat water? Posted: 26 Jan 2020 03:12 PM PST With the recent rise in popularity of carbonated waters, I feel this is an important question regarding suggested daily intake. Personally, I feel less hydrated after drinking a can of La Croix or bottle of Pellegrino as opposed to a glass of water. Is it because I equate carbonation with soda or are my observations valid? Please (dis)prove with an explanation. Thanks! [link] [comments]  |
