| Posted: 21 Sep 2020 03:18 PM PDT I wonder if a non-sterile probe may have left Earth, have all but the most extremophile / adaptable microbes survive the journey, or microbes capable of desiccating in the vacuum of space and rehydrating once in the Venusian atmosphere, and so already adapted to the life cycles proposed by Seager et al., 2020?

| What are the effects of non-specific antibody binding inside the human body? Posted: 22 Sep 2020 04:06 AM PDT We use antibodies in research all the time and despite the best efforts to raise them in a way that makes them specific to a particular epitope, we often see some level of non-specific binding. This got me wondering what the effects would be if this were to occur in a whole organism, presumably antibodies will often bind things that aren't their intended target. Are immune responses mounted as a result? [link] [comments]  |
| Do people infected by asymptomatic carriers of SARS-CoV-2 also develop less prominent symptoms? Posted: 22 Sep 2020 01:11 AM PDT I'm wondering if an asymptomatic display of the virus has at least partly something to do with the constitution of the virus itself, and therefore the viruses that will be replicated from it in other hosts. In other words - do asymptomatics spread a slightly different version of the virus? [link] [comments]  |
| How was the formula to graph the trajectory of a projectile derived? Posted: 22 Sep 2020 04:16 AM PDT The formula to graph the trajectory of a projectile is y = x tan θ - (gx2 ) /(2v2 • cos2 (θ)). θ is the initial angle of the projectile g is the downwards acceleration due to gravity (9.8 on earth) v is the initial velocity of the projectile How this formula was derived?

| How can leukemia cause leukopenia? Posted: 22 Sep 2020 05:15 AM PDT though it most commonly cause leukocytosis, I've read it sometimes cause leukopenia. How does that work? [link] [comments]  |

| Why does parkinsonism have both hypokinetic and hyperkinetic features? Posted: 21 Sep 2020 11:20 PM PDT I've read it like nigrostriatal pathway has an inhibitory effect on motor activities(dunno If I'm wrong there),so theoretically only hyperkinetic features are expected,right?

| Is it possible to make a curve that takes up a full plane? Posted: 21 Sep 2020 09:19 AM PDT The larger question I am asking is, could an object in n-2D entirely fill the space of Dimension N? I smoked a few bowls after a T break and thought about black holes. I thought maybe black holes were so big they couldn't fit in 3 dimensions, and maybe they could fit an infinite amount of mass in one place in three dimensions, and it was curved infinitely over a larger plane in a higher dimension, creating a curved line in 4D and merely a point in 3D. Then I asked myself if it would be possible to calculate a line within 3D space that had such a steep curve it took up the full entirety of the plane? Since a line and a plane are both infinitely large, and a line is infinitely thin, it would just need to crinkle so randomly that it hit every point and every point between each point or exponentially gradient along itself so no point is ever missed? I am just high and felt like typing this all out because now I really wanna know the answer. Thank you for Humoring me [link] [comments]  |

| Does isodicentric 15 syndrome render a person infertile? Posted: 21 Sep 2020 09:31 PM PDT Title. If yes, does every chromosomal disorder render a person infertile? [link] [comments]  |
| How does insulin resistance happen? Posted: 21 Sep 2020 11:28 AM PDT What changes in the cells where they no longer use/recognize the insulin correctly? [link] [comments]  |
| Posted: 20 Sep 2020 11:32 PM PDT I've been learning a little about the Morgan-Keenan system for stellar classification. In this system, categories of stars are arranged in order of their temperature and assigned a letter. From hottest to coolest the letters are O, B, A, F, G, K, M. My question is, why these seemingly arbitrary letters that don't obviously map to anything or go in any order? Wouldn't A, B, C, D, E, F, G have made more sense? [link] [comments]  |
