| How does alcohol (sanitizer) kill viruses? Posted: 30 Jul 2020 06:05 PM PDT Wasnt sure if this was really a biology question, but how exactly does hand sanitizer eliminate viruses? Edit: Didnt think this would blow up overnight. Thank you everyone for the responses! I honestly learn more from having a discussion with a random reddit stranger than school or googling something on my own [link] [comments]  |

| Why dont we kill HIV/ AIDS by killing the immune system? Posted: 31 Jul 2020 02:13 AM PDT Alright so I was prepping a lesson for class, where I need to cover HIV in the work place. My question is, since the virus cannot survive without attaching to and replicating through a cell(specifically for HIV,cells with the CD4 molecule) why do we not just use a process such as chemotherapy to kill the cells, stick the patient in a clean room for however long it takes for the virus to die and then restart the immune system through bone-marrow transplants or something that might actually work. It might be like taking a butchers knife to the patient, I'm just curious if this has been looked into. Forgive me if this is a dumb question, its definitely not my field. [link] [comments]  |

| Posted: 31 Jul 2020 02:25 AM PDT The cosmic background radiation temperature had been measured to be uniformly ~2.7 K. Doesn't this contradict the equation stating that the CMBR temperature at some redshift z is equal to ~2.7 * (1 + z)? I believe the universe is redshifted more at farther distances, so wouldn't this mean that the CMBR temperature increases as you go farther out in the universe and therefore isn't uniform?

| If our body knows how to fight off (non-novel) viruses how do we still get sick? Posted: 30 Jul 2020 12:17 PM PDT Like how do we get standard colds and the flu if our body recognizes it and knows how to fight it. [link] [comments]  |

| Should I consider climate change effects when buying a home? Posted: 30 Jul 2020 05:15 PM PDT Ok so this may be the wrong place to ask this, but... I'm planning on buying a house soon and I've been wondering if I should take climate change into consideration. I live on a coastal area (south Louisiana). Does anyone know of a website or something where I can check areas at risk of flooding? Or should I just get out of the area while I still can? Thanks and sorry if this isn't the right sub for this.

| Where do mosquitos hang out/spend their time? Posted: 29 Jul 2020 11:20 PM PDT How are they able to so quickly be on you every time you step outside? [link] [comments]  |
| In some place in the universe would The CMBR just be visible light? Posted: 30 Jul 2020 05:39 AM PDT If the Cosmic microwave background radiation is in the microwave range due to the expansion of the universe stretching the light does that mean at some point in the universe there is this ring where if you lived there you would be blinded in all directions by just really bright lights?

| What methods/techniques exist to measure waterborne microplastics in-situ? Posted: 30 Jul 2020 02:37 AM PDT I'm an electrical engineer who's been looking into how to measure microplastics in remote water supplies, and I'm trying to get my head around what methods or technologies exists that might make this possible. The end goal is being able to pump a sample into a vessel/tube, take a measurement, then flush it out. So far I think Raman spectroscopy might be a possibility, as well as FTIR spectroscopy, but I lack the scientific know-how to understand if these are reasonable approaches and what the pros and cons are for each. I've also come across this microplastics analyser, but I don't fully understand the methods behind it. Could someone with expertise in this areas please help me out? [link] [comments]  |
