| Is the Immune Response to Poison Ivy or Mosquitos Nessecary or is it a Defect? Posted: 01 Jun 2020 01:55 AM PDT I recently moved to the Great Lakes, and there are a LOT of things in this environment that my immune system does not like. I have had adverse reactions to poison ivy, chiggars, stinging nettle, and mosquitos that have covered my skin in welts. I understand that this is the result of my immune system reacting to a foreign chemical introduced into the body. But what I don't understand is why? The oil from poison ivy isn't a virus or an infections agent. So why does the immune system attack it? Are these the results of a defect in our immune system, or does the body attack these substances and the cells they encounter to prevent a larger problem? PS: NOT medical advice, I have a Dr, my symptoms are under control, I'm not in danger of anaphylactic shock or anything like that. Just VERY uncomfortable. [link] [comments]  |

| Posted: 01 Jun 2020 12:59 AM PDT Basically the title. Generally, a person "should" get his/her blood tested at least once a year; normal check-ups. I know that the only secure way of knowing whether you have HIV or not is to get tested specifically for it, but there's something I have been thinking about all the time. When there is an infection of any kind, some values just exceed the normal ranges and your doctor may ask you to investigate about it further. Wouldn't that be the same, exact thing for HIV?

| When viruses infect us and inject their DNA into our cells, does that (eventually) alter our genome? Posted: 31 May 2020 01:00 PM PDT if that is unclear, what I'm trying to understand is that after I beat any viral illness, does the injected DNA still exist in me? Will it continue to replicate, though not necessarily the self-reproduction genes for the virus, but any other lingering genes? If I beat a flu when I was a child, though I do have the antibodies for the virus itself, does that old flu still have its injection in me, somewhere? [link] [comments]  |
| Do insects have a sense of hearing? Posted: 31 May 2020 05:02 PM PDT They certianly make a lot of noise - so i suspect some speicies do. But what about a beetle or a bee? And if the answer is yes - how do they hear? Do they have ears? [link] [comments]  |
| Posted: 01 Jun 2020 05:32 AM PDT I know basics of optics but it just doesn't get into my head how this works Whenever there is a concave mirror projecting light somewhere and you put for example a piece of cardboard with a hole between the source and the mirror the size of the projected object doesn't change..... Like my telescope is barley big enough to cover the full moon on the eyepiece and I have a cover that reduces the size to about 1/5 but the moon is still fully visible... It's just much darker I saw the same thing in a veritasium video where he bounced light off of an concave mirror and then he reduced the size of the light source [link] [comments]  |
| Posted: 31 May 2020 04:38 PM PDT Since red blood cells have no nucleus or mitochondria, what made it possible to establish the differentiation of blood groups? Does it come from the plasma? Sorry for the multiple questions, as this brought some great confusion to me. [link] [comments]  |
| What changes in the designs of wires and connectors to make them faster across generations? Posted: 31 May 2020 03:52 PM PDT Why is USB 1.0 so slow despite being bigger than USB 2.1, and how is the newest USB wire so much faster than both of those? [link] [comments]  |
| Is there any theory that predicted the Cosmic Microwave Background Radiation before it was measured? Posted: 31 May 2020 03:18 PM PDT I know that there are theories that talk about how the Universe was 1 second/3 minutes/10 years/ etc... after the Big Bang. Did any of those theories predict the CMB? Was there ever any reason to expect anything like it before we discovered it? [link] [comments]  |

| Did the earth always have an atmosphere? Posted: 31 May 2020 01:30 PM PDT My kid asked me that and I wasn't sure about the answer. Of course I know that the amount of gases changed over time - but when was there some sort of proto-atmosphere for the first time, as a layer of gas around our planet? [link] [comments]  |
| Is Antibody Plasma blood type sensitive? Posted: 31 May 2020 06:19 PM PDT Been watching 60 Minutes about Antibody Plasma and wondering...once the plasma is spun off of the blood of someone with antibodies, can that plasma be used by anyone with corona virus, or do donor and user have to have matching blood types?

| How do people develop personality traits? Posted: 30 May 2020 11:53 PM PDT I am super competitive, I love being in competitions and testing myself against others. I'm not insecure, I don't have anything to prove, I'm not an adrenaline junky and I don't fill any of the boxes for why people are competitive. I just love competing: chess, basketball, track, soccer, online gaming such as CS:GO and planetside 2, debate, you name it I'll play it. Why is this, because I am kinda introverted and nerdy. I love physics and am a book worm — why do people develop these kind of things? [link] [comments]  |
