- If I donate plasma for covid 19 trial therapy could I reduce my own immunity to the virus or will my immune system just make more antibodies?
- Is the smell of disgusting odor (sewage/manure/human or animal feces) actually damaging to your health? Does disease transmit through smell?
- What do we mean when we say stuff like, "The End-Permian Mass Extinctiom wiped out 96% of all life on earth"?
- How are barrier islands formed?
- How long would a virus be able to survive in space? Can a virus be “frozen”? Why wouldn’t it freeze in space?
- mAbs production: Do hybridomas contain twice the amount of DNA?
- The Mid-Atlantic ridge ends in the middle of the Arctic ocean. Is this a coincidence of current continental alignments or are there other factors in play related to its polar location?
- Why can frequencies be measured more precisely than other physical quantities?
- Why do we get depressed without even knowing the cause?
- Why do we talk about 4 fundamental forces, when electroweak combines 2 of them?
- Can ants run, or do they always move at the same speed?
- Roughly how long did it take for the solar system to form after the molecular cloud fragment began to collapse?
- Of we were to send mirrors into space in all directions, would we be able to look back in time once the mirrors have travelled far enough?
- Metallurgy: When melting metals to produce parts or beams for things, what stops the metal pot/cauldron from getting to melting point and just combining with the melted?
- Why does doxycycline (and related antibiotics) cause nausea?

| Posted: 15 Jun 2020 07:42 PM PDT Basically, if I work at a sewage treatment plant, is the smell of human waste actually harming my health, beyond the discomfort? [link] [comments]  |
| Posted: 16 Jun 2020 07:01 AM PDT Digging further into this specific expression as an example I've found that the numbers vary greatly between 96% of "marine species", to 70% of all terrestrial vertebrates. However when we say, "marine species" or, "life" are scientists referring exclusively to macroscopic or even multicellular life, or does this include microscopic life, bacteria, protozoans, etc.? I have always assumed that this is was scientific communication shorthand. Surely, I figured, not 96% of all living organisms from all branches of the tree of life, could have been wiped out. For starters the archaeological evidence of bacterium must be inadequate to assign a significant mapping of genera (let alone species), and thus deduce a rate of extinction for most microscopic life... Or am I wrong, and these types of expressions should be taken at face value? Please help! This has been eating me for almost 2 decades now, and I honestly can't take it any more! [link] [comments]  |

| mAbs production: Do hybridomas contain twice the amount of DNA? Posted: 15 Jun 2020 10:17 PM PDT In the making of monoclonal antibodies, myeloma cells are merged with spleen cells using PEG. I understand that the cells are 'merged'. Will this mean that the resulting hybridomas have 2 nucleus? [link] [comments]  |

| Why can frequencies be measured more precisely than other physical quantities? Posted: 15 Jun 2020 06:55 AM PDT I've been reading about mass spectrometry in a text book. It was described that FT-ICR mass spectrometers deliver the best resolution of any mass spectrometer because frequencies can be measured more precisely than anything else. Why is that? How much better can it be measured than other things? Are there any quantities that can be only be measured very unprecisely? Also, can someone recommend literate about this topic? I'm not a physicist and find it hard to search for specific physics related things. [link] [comments]  |
| Why do we get depressed without even knowing the cause? Posted: 15 Jun 2020 02:45 AM PDT So I just got to thinking. With all the amazing things our body can handle on its own, and signal to our brain. Ie. If you hurt yourself, you will be able to tell where it hurts, and you make out the when and where. So how come mental health is so tricky for the body to mediate? How is it some people can go around for a bigger part of their lives feeling depressed without knowing why. Why is it the brain "neglects" why you are feeling bad ? [link] [comments]  |
| Why do we talk about 4 fundamental forces, when electroweak combines 2 of them? Posted: 15 Jun 2020 05:30 PM PDT Conventionally we talk about four fundamental forces: Electromagnetism, Strong and Weak Nuclear and Gravity. But we've known since the '70s that Electromagnetism and the Weak Nuclear are the same Electroweak Interaction, just at different energy levels. So should we not say there's 3 fundamental forces?

| Posted: 15 Jun 2020 12:27 PM PDT I understand that the age of the solar system is tied to the oldest solid material it is thought to have formed. But how long was the time between when the molecular cloud fragment of the pre-solar nebula which formed our solar system began to collapse and the formation of this oldest known material from the solar system?

| Posted: 15 Jun 2020 06:42 AM PDT If it is just a metal with a higher melting point, then what about when you want to melt that and make parts out of that? [link] [comments]  |
| Why does doxycycline (and related antibiotics) cause nausea? Posted: 15 Jun 2020 09:28 AM PDT I've attempted to google this, but it's all just lists of side-effects. My question is, what is the specific mechanism that causes the nausea? My best guess is that it kills good bacteria in your stomach, and the stomach interprets this as a disease of some kind, but I'm not sure if that's true. Thanks! [link] [comments]  |
