| Any news from Tinnitus Treatment? Posted: 22 Apr 2021 08:34 AM PDT Is there any progress in tinnitus treatment? I have seen some 10 year old posts here talking about possible cures. The post was archived so I couldn't write on it. I'd like to know what has changed so far in 10 years. [link] [comments]  |

| Why are there different tresholds to reach herd immunity for different diseases? Posted: 22 Apr 2021 02:14 AM PDT I thought it was a quantitative concept, applicable for all kind of diseases, as numbers do not differentiate between them. Why is it for Covid considered to be ~70% but for measles ~90%? Thank you. [link] [comments]  |
| What determines a greenhouse gas? Posted: 22 Apr 2021 12:12 AM PDT Part of my university chem course goes over gases. I understand how polarity and the vibrations of the molecule determine if the molecule is a greenhouse gas. The one thing I do not understand is how methane is a greenhouse gas - its a non-polar molecule and therefore will not have any change in dipole during vibrations so how is it infrared active and a greenhouse gas??

| Posted: 22 Apr 2021 01:47 AM PDT In False-positive COVID-19 results: hidden problems and costs30453-7/fulltext) it is said:
My questions:
To clarify. Let us, for the sake of example, say that the false positive rate they are talking about is 1%, and one day we test 100.000 people, and that we get 5000 positive results.. Will that mean that: A: 1% of the 100.000 are false positives, therefore there are 1000 false positives? or that B: 1% of the 5000 that tested positive are false positives. Therefore, 50 are false positives? [link] [comments]  |

| How do vaccination rates affect reproduction rates? Posted: 22 Apr 2021 02:16 AM PDT Ha, I hope I'm not the only one who is still confused by corona. I've read a few articles about "herd immunity" and the vaccination levels required for that. But it seems to me that that current transitional stage of many countries also makes the reproduction factor R rather than full herd immunity relevant. Say you have a country with R 1.1 with no vaccinations and the numbers are therefore increasing. If 25% of the population are vaccinated, does this reduce R below R 1 and therefore leads to falling infection numbers (all other things being equal)? Are there enough data to model these relations yet? Thanks :) [link] [comments]  |
| Was there a tendency for someone not to be immunized by more than one type of vaccine? Posted: 22 Apr 2021 04:41 AM PDT Vaccines are an effective method of preventing disease because a considerable portion of people are immune after taking it. But that does not happen to everyone. Would there be a study to show if there would be a tendency for someone who was not immunized by one particular vaccine to not be immunized with another vaccine? Something like vaccines don't work on that person? Would there be any factors for this to happen, if there is one? [link] [comments]  |
| Posted: 21 Apr 2021 11:34 AM PDT Do bees and ants ever send out groups of hive members to look for other hive members that haven't come back or have gone missing? Like if I kill an ant in my kitchen, will more ants come looking for that ant? [link] [comments]  |
| Why does it take 2 weeks to get immunity after 2nd covid vaccine? Posted: 21 Apr 2021 10:05 AM PDT Typically people have mild symptoms after getting the 2nd covid vaccine and recover after about a 24 hours. Why does it take 2 weeks before you have immunity rather than 24 hours? Hasn't your body already fought off the virus when your symptoms go away? [link] [comments]  |
| Posted: 21 Apr 2021 02:26 PM PDT The body is responsible for making thousands of different types of proteins, not a single one of which (normally) triggers an immune response. So, how does the immune system recognize one specific new type of protein that is made by the body's cells when instructed by mRNA vaccines? Additionally, why is this effect not seen in genetically modified animals that are modified to express the Green Fluorescent Protein (GFP) used in genetics and tissue studies, since that is also a foreign protein that the body is instructed to make?

| Posted: 21 Apr 2021 03:48 PM PDT I heard that chips were meant to make credit cards more secure. But then I just read that if a chip is used for a fraudulent credit card transaction and you say the card was with you at the time, the credit company will say it can't be fraud. What's so special about these chips that companies can be so confident it's not fraud, while at the same time apparently remaining vulnerable to fraud? (Not sure about the flair sorry) Edit: this is the post that made me wonder these things. So many commenters saying they experienced fraud on a chipped card only to be dismissed by the company, so i wondered about the tech in question. [link] [comments]  |
| Is the Size Variation Found Among Humans Typical for Mammals, or is it in Some Way Unique to Us? Posted: 21 Apr 2021 03:42 PM PDT Hello everyone. Do other mammals also display a similar internal length diversity and variation in size, or are humans unusual for having a particularly large (or small) variation in length? [link] [comments]  |
| Posted: 21 Apr 2021 03:41 PM PDT The article: https://www.sciencedaily.com/releases/2020/11/201105113006.htm How accurate is this? [link] [comments]  |
| How does our body make stomach acid? Posted: 21 Apr 2021 09:26 AM PDT Basically the title. I know our stomach needs to produce mucus to prevent the acid from eating us, bit where does the acid come from? Is it produced in the stomach by mixing two other chemicals/materials? What is it's chemical components and how do we get them? [link] [comments]  |
| Why does an open cut sting when alcohol is applied to it? Posted: 21 Apr 2021 01:10 PM PDT I was wiping my hands with hand sanitizer and forgot that I'd gotten a small cut on one of my fingers earlier that day. As I was wiping, that area started to burn/sting pretty badly. This has happened to me before, but I'm curious why it occurs. Thanks! [link] [comments]  |
| Do we see writing systems impact spoken syntax? Posted: 21 Apr 2021 01:49 PM PDT Do we see any impact from writing systems on the syntax of spoken language? My understanding is that cultures often have to adapt foreign writing systems to suit their language, like in Japanese (ie hirigana etc) . Do we see changes over time to spoken syntax when a culture adopts a writing system? And are languages with more native writing systems influenced by the evolution of their written forms?

| What is it about sleeping that builds muscle memory? Posted: 21 Apr 2021 08:39 AM PDT I've noticed when I'm practicing something on the guitar, if i do it for an hour or two that day, i will see very little almost no improvement in that same day, but when i go to sleep and wake up the next day it's almost like i got exponentially better over nigh. Yesterday i decided to learn some csrdistry tricks, and same thing, one handed cuts and things like that i could barely get without dropping cards, this morning i wake up and it's like all the practice from yesterday hit me simultaneously this morning. What happens while you sleep that your brain is like "okay tomorrow we got this"?? Idk what to flair this, i guess psychology? Or maybe biology? [link] [comments]  |
| If PTSD is said to physically change the brain do we know how C-PTSD physically alters the brain? Posted: 21 Apr 2021 07:55 AM PDT Questions in the title. Simply put I have been wondering how C-PTSD or Complex post tramautic disorder physically impacts the brain. I know PTSD enlarges the amygdala but PTSD revolves around one trauma. Whereas CPTSD is long continual trauma so if one traumatic event can change the brain I imagine a whole third or more of your life filled with trauma might as well. [link] [comments]  |
| Does moisture/humidity increase sense of smell? Posted: 21 Apr 2021 12:06 PM PDT The strong smells of swamps, perfume, the ocean.... got me thinking that moisture/wetness seems to correlate with strong smells. Also, once things get wet, their smell gets stronger: wet dog, wet grass, etc... This got me wondering if something about the way we perceive smells has to do with moisture? Does humid air transfer scents to our noses better? Do the hairs in our nose trap small water molecules and transfer whatever triggers our sense of smell? [link] [comments]  |
