| Is misophonia culturally dependent? Posted: 18 Jun 2021 11:38 PM PDT In some cultures, it's considered polite to eat loudly. In my house, I might kill you for it. Is misophonia something that manifests significantly differently from culture to culture like schizophrenia does? What are some unique ways in which it manifests, if so? [link] [comments]  |
| Are there different types of magnetic fields? Posted: 19 Jun 2021 05:58 AM PDT A general compass will point towards the magnetic north of the earth. But when an external magnet is kept near the compass, the compass will point towards the stronger magnetic field in its vicinity. Are there different "frequencies" in magnetic fields such that the measurement of one field might not get affected by the other? [link] [comments]  |

| What is the Delta variants mortality? Posted: 18 Jun 2021 12:24 PM PDT I'm seeing 10,000 new cases a day in the UK and no increase in the death rate. Is there good data on the mortality of the delta variant? [link] [comments]  |
| Why do Side Bands exist in AM radio? Posted: 18 Jun 2021 08:22 PM PDT I'm struggling to understand why side bands occur. Usually the explanations I see online just say "because of the math" and leave it at that. If AM changes the amplitude of a signal, why does that cause a signal on the wavelengths above and below the carrier frequency? [link] [comments]  |
| Is oxygen percentage the same across all layers of the atmosphere? Posted: 18 Jun 2021 02:19 PM PDT Hello, I know that although the amount of air decreases as you go up, the ratio of different gases in air remains the same. But is this true across all layers? Is the Oxygen percentage still around 21% in the stratosphere and beyond? Another question is why does seawater have a higher percentage of nitrogen and oxygen? And is this true across all water temperatures? [link] [comments]  |
| I saw a weird rainbow ring around the sun today and I don’t know what it was? Posted: 18 Jun 2021 12:29 PM PDT I thought it was window glare, but i saw it outside and my phone kinda picked it up. Does anyone know what it is? I was in mississippi i think if that helps [link] [comments]  |
| Do viruses mutates everytime it infects someone? Posted: 19 Jun 2021 01:19 AM PDT Do viruses mutate everytime it infects someone? Not necessarily into a more infectious or deadlier strain but do they mutate everytime they infect someone. [link] [comments]  |
| Do paper towels suppress microwaves? Posted: 18 Jun 2021 02:07 PM PDT So, I have these little Kraft mac'n'cheese microwave bowls and was really annoyed that they kept spewing water all over my microwave, so I put a layer of paper towels underneath the bowl to catch the water. I expected for this to just make the cleanup process easier, but was surprised when the paper towels were completely dry. And it wasn't just that the water had dried out from the paper towels either, the water had completely stayed inside the bowl, making the mac'n'cheese much nicer IMO. I'm just wondering if the paper towels are suppressing the microwaves … and if that means that the water is therefore not getting as hot. Ask me questions if you need to, but I think I gave enough of a backstory ;) Sidenote: If you have this problem, I hope this solution helps <3 [link] [comments]  |
| How are action potentials spontanous, and where does the energy come from? Posted: 18 Jun 2021 02:21 PM PDT Hi! I've looked all over for an answer to this question, but can't seem to find an answer online that clarifies things for me. When describing the action potential, and the electrochemical gradient that forms it, I often see an ion as described as flowing down its respective concentration gradient. For example, during depolarization, sodium flows into the cell, from an area of high concentration to low concentration (of sodium). During depolarization, the same occurs, with potassium flowing out of the cell. All through selective ion channels of course. My first issue is, how are these individual gradient physically justifiable? Isn't diffusion determined by the overall concentration of ions (since they are bouncing off each other and creating a "pressure" that is lower in an area of lower concentration)? Wouldn't the overall osmolarity be the only relevant factor? My second issue come from what's probably a bad assumption. I did a bit of searching and found that the extracellular fluid has a higher osmolarity then the intracellular fluid in a neuron. That combined with the difference in charge of -70mV sort of explains the depolarization step and its eventual charge of +30mV. As part of the energy is derived from the difference is concentration, and the rest a difference in charge, I can see why depolarization would be spontaneous. It also explains to me why it "overshoots" and another +30mV of charge are produced across the membrane, as additional energy from the resolution of the concentration difference is "stored" as a positive electrical potential. My next issue is, if depolarization is spontaneous (based off of the assumption I made above), how does hyperpolarization occur to restore the membrane potential to an EVEN HIGHER negative voltage. How could this be spontaneous? With the lower osmolarity inside the cell, this makes little to no sense to me. I thought the energy might have come from the ATPase pumps in the cell membrane, but I've read that hyperpolarization is so fast, these cannot explain the restoration of the electrochemical gradient. Could anyone tell me where my erroneous thinking is? Anyone have a good breakdown of how the action potential occurs? Any help is appreciated! [link] [comments]  |
| Oceanic algae produce most of the world's oxygen, but do they also sequester carbon? Posted: 18 Jun 2021 08:29 AM PDT Do the algae "produce" oxygen by splitting atmospheric carbon dioxide? And if so, does the carbon stay in the oceanic food chain or circulate back into the atmosphere somehow? [link] [comments]  |
| How does the Bravo capsule detach from the esophagus? Posted: 18 Jun 2021 06:42 AM PDT I've done a bunch of googling to no avail, I just keep reading that it "detaches naturally after a few a few days". How does it actually detach? [link] [comments]  |
