| [Medicine] What is special about peanuts that make some people extremely allergic to them? Posted: 26 Sep 2020 05:48 PM PDT Why are some people allergic to peanuts in particular? Why is ingesting a peanut to these people akin to ingesting poison to others? [link] [comments]  |
| Why is so much focused placed on a COVID-19 vaccine, rather than an effective treatment? Posted: 26 Sep 2020 03:51 PM PDT At least in my country, sufficient numbers of people are so likely to refuse any vaccine that I can't see how it would actually be effective. So I wonder if anyone can tell me about the state of treatment research, and whether anti-virals are even an option with COVID-19 or whether the focus of treatment has been mainly on fixing the symptoms, not eliminating the virus itself. Thank you in advance! [link] [comments]  |
| Posted: 27 Sep 2020 01:22 AM PDT Mount Chimborazo's peak is 2km farther away from the Earth's core than Mount Everest, but Mount Everest's peak is the highest above sea level. Which peak has the thinnest atmosphere? [link] [comments]  |

| Posted: 26 Sep 2020 10:21 PM PDT I have read that an element can produce electrons and donate them if there is a bright light shined on it. Are there other ways to execute this? Could this apply to elements that are not typically donors like noble gases, silicon, etc? [link] [comments]  |

| Posted: 27 Sep 2020 06:19 AM PDT Are there any data on what percentage the current population have had COVID-19 and are currently living with antibodies to protect against future attacks? Is it anywhere close to what's necessary for herd immunity? If the spread can be contained so medical centres don't collapse under the pressure, assuming no valid vaccine is found, how long would herd immunity take to achieve? [link] [comments]  |
| Posted: 26 Sep 2020 10:36 AM PDT I've recently stumbled into an area of mathematics and ancestry that doesn't sync well with the knowledge that humans have been around for approximately 1M+ years and that our population level has only recently begun to spike. I'm hoping the community can help me reconcile this all. The problem stems from the number of people who are required to bring about the next, subsequent generation. When considering what it took to bring me into existence, the numbers become impossibly large. Example: For both my parents to exist, they each needed two sets of parents (4 people, my grandparents), and likewise for their parents to exist they would need 4 sets of parents (8 people, my great grandparents). There is a doubling effect for each generation, expressed as 2X where "x" is the number of generations away from myself. I've recently been researching my ancestry and realized that at least one branch of my tree can be traced back 15 generations. What I realized is that by the 15th generation, it would've taken 32,768 great15 grandparents to make the 16,384 children who would become my great14 grandparents. From there, 16,384 would bear 8,192 children and so forth all the way to my parents 21. That's a grand total of 65,532 grandparents over the course of 15 generations that were needed in order to produce the 2 parents necessary for me to come into existence. That's obviously a lot of people and in a relatively short amount of time. If I make a rough estimate that each generation is separated by 25 years, then that means 15 generations ago was the late 1500s, which also lines up very well with the date of birth listed for my great15 grandfather in 1577. So, the estimated separation of 25 years is a reasonable approximation. Now, what happens if we go back 30 generations? The math becomes impossibly large. 230 = 1,073,741,824, which means that I have this many great30 grandparents, and applying the same approximation as above, this puts us right around Viking times in the year 1200. And I don't believe the world population was even that high in this era. It was estimated to be less than 400M according to this. Even more so, going back just 6 generations further, at generation 36 (approximately the year 1100), the number of grandparents at this generation and totaled with all grandparents of every generation subsequent to them brings the total number of people who are needed to create me to 137,438,953,470. This is larger than the estimated number of people who have ever lived on Earth. So, please help. Where does this model break down? Obviously, there has not been this many people that existed in the last 1000 years, but I can't see how to reconcile this with the knowledge of a (seemingly unbreakable) constant that 2 parents much come before 1 child, always.

| What degree of human interpretation is required for COVID-19 PCR test diagnosis? Posted: 26 Sep 2020 12:27 PM PDT I guess the same might apply to other PCR tests (like STD tests and such). I know that they involve some kind of DNA isolation, replication and identification. I was wondering what degree of human interpretation is required to get to a positive or negative diagnosis. Is there a machine that just outputs the definitive, final result? Or is there a final step where a human needs to read some kind of output and make a determination out of it, perhaps with some kind of threshold? Or is it somewhere in between? [link] [comments]  |
| How does alcohol and other drugs damage the liver? Posted: 26 Sep 2020 03:31 PM PDT Background: based on my admitadlly shallow knowledge of the human body; the liver processes harmful substances like alcohol and other drugs. Long term abuse of drugs like alcohol can lead to permanent liver damage like cirrhosis. My question is do we know how the damage process works? Is it like a preset volume of toxic substances before it stops working? For example 10000 beers before there liver goes, or is it based on other factors? [link] [comments]  |
| How do researchers interface with quantum computers? Posted: 26 Sep 2020 09:03 AM PDT Given that quantum computers are still in the experimental phase, and there is no off-the-shelf hardware or peripherals to control and interface with them (I'm assuming), how do researchers working with them send commands and receive feedback? I'm guessing there's no monitor or GUI displaying data, or any plug & play peripherals. [link] [comments]  |

| How much biomass is there at the end of extraction events? Posted: 26 Sep 2020 10:32 AM PDT There was an article recently about the weight of biomass on the planet being half of what it was pre industrial revolution. Is there research on how much biomass there is before, during, near the end, and after the previous mass extinction events? Did the few surviving species make up for the loss in biomass of the recently extinct species or was in vastly smaller until new species evolved into the new niches? [link] [comments]  |
| How Many Pions Are There Inside a Boron Nucleus? Posted: 26 Sep 2020 09:22 AM PDT Hi, I'm trying to 3D model (in Blender) a boron atom (a boron trifluoride molecule actually) from quarks and gluons all the way up to valence electrons. I know there are 5 protons and 5 neutrons in boron's nucleus and I know that an exchange of pions between these hadrons keeps the protons from repelling each other electromagnetically. I understand that each proton is two up quarks and a down, each neutron is two downs and an up, and that each pion is an up and an anti-down. All I need to know is how to determine the number of pions inside the nucleus, holding the hadrons together. Is it the same as the atomic number? Twice the atomic number? One single pion per nucleus? I have no idea. Same for fluorine while we're at it. Please and thank you. [link] [comments]  |
| Posted: 26 Sep 2020 07:21 AM PDT Disclaimer: I'm a very pro-environment and we should do our best against the CO2 emissions.But I saw on "Paleoclimate" wikipedia page this graphic showing the average world temperature since the cambrian https://en.wikipedia.org/wiki/Paleoclimatology#/media/File:All_palaeotemps.svgWe can see that between 50 to 10 millions of years ago the Earth was VERY warm much more than the 2 degrees that alarm scientists today, and we can also see that the hot times were the majority and the cold times the exception. That made me think, is the global warming that much of a problem? We could live in a world as hot as it was 20 millions of years ago, or not? If not, why not? How the Earth was back then? It was too different? [link] [comments]  |
