| When does cancer become terminal? Posted: 07 Aug 2019 02:27 AM PDT People with cancer survive with an operation or some sort of medical treatment but when the doctor says it's terminal, when exactly does that happen and what does it mean? Is it possible to survive after the cancer has been termed as terminal? [link] [comments]  |

| Is -5 minimal possible reduction state for an atom or a molecule? Posted: 07 Aug 2019 12:43 AM PDT As far as I understand, it is possible to strip a nucleus from all of its electrons and ionize it as far as to its proton number (+6 for C, +7 for N etc). My understanding is that nothing terrible will happen to the nucleus and it won't break apart or "generate" missing electrons from nothing. But how far can you go in the opposite direction? I know it is possible to fill the outer electron shell of a nucleus, i.e. reduce boron to -5 or carbon to -4, but is it possible to go further, i.e. "wrap" an extra electron shell around a nucleus? Or at least go up to -6 or -7. Would extra electrons "fly away"? What exactly keeps electrons from leaving an anion with a full outer shell? Edit: I guess the title should have been "for an ion"?..

| Posted: 06 Aug 2019 11:53 PM PDT For example BeCl2 is Nonpolar in terms of net dipole forces but its DeltaEN is 1.5 which would catagorize it as a Polar covalent bond. So is BeCl2 Polar or Nonpolar? [link] [comments]  |
| Roasting coffee - does it change caffeine levels? Posted: 06 Aug 2019 10:15 AM PDT I understand that caffeine has a melting point of 455 degrees, (F) and as a coffee roaster I know that roasts don't go that far. To my mind this would mean that there should be no discernible difference in caffeine content between a light, medium or dark roast. I have also read this short paper by Juliet Han, which appears to confirm this (with a few outliers). However! Is there any other method by which caffeine could be released from the coffee beans during the roasting process? In such a way that would make any appreciable difference between a light and a dark roast? I was thinking of things like evaporation and sublimation, but I don't know if they would apply to the roasting process. [link] [comments]  |
| Posted: 06 Aug 2019 10:03 AM PDT As above: For example- Would a gamma ray released from decaying radium result in a nearby carbon atom becoming radioactive itself due to it's ionisation? [link] [comments]  |
| Posted: 06 Aug 2019 04:02 AM PDT At 1 billion ly apart, the balls would ordinarily be receding from each other at about 160,000 km/s due to cosmological expansion. If the rope is keeping them at the same distance, is it possible to calculate the rope's tension? [link] [comments]  |
| Do people with Situs Inversus need similarly flipped organs for transplants? Posted: 05 Aug 2019 09:14 PM PDT In the recent Hitman game a plot point is made about the fact that a character has Situs Inversus and has to resort to fishy activities to get a desperately needed heart transplant from another person with Situs Inversus, under the logic that a regular heart has the wrong orientation and would be useless for transplant. My question is, do people who actually suffer from Situs Inversus in real life need organs for transplant like hearts to match the orientation of their organs? As such would they then need to get these organs from other people with Situs Inversus? Or does it matter all that much and are there ways of 'Jerryrigging' the body to accept a regularly orientated heart in this circumstance without major side effects? [link] [comments]  |
