| AskScience Panel of Scientists XXII Posted: 24 Jan 2020 05:32 PM PST Please read this entire post carefully and format your application appropriately. This post is for new panelist recruitment! The previous one is here. The panel is an informal group of redditors who are either professional scientists or those in training to become so. All panelists have at least a graduate-level familiarity within their declared field of expertise and answer questions from related areas of study. A panelist's expertise is summarized in a color-coded AskScience flair. Membership in the panel comes with access to a panelist subreddit. It is a place for panelists to interact with each other, voice concerns to the moderators, and where the moderators make announcements to the whole panel. It's a good place to network with people who share your interests! You are eligible to join the panel if you:
Instructions for formatting your panelist application:
Ideally, these comments should clearly indicate your fluency in the fundamentals of your discipline as well as your expertise. We favor comments that contain citations so we can assess its correctness without specific domain knowledge. Here's an example application: Please do not give us personally identifiable information and please follow the template. We're not going to do real-life background checks - we're just asking for reddit's best behavior. However, several moderators are tasked with monitoring panelist activity, and your credentials will be checked against the academic content of your posts on a continuing basis. You can submit your application by replying to this post. [link] [comments]  |
| Why do moles grow such long hairs? Posted: 02 May 2020 01:29 PM PDT Some moles grow hairs much longer than the surrounding area, why? [link] [comments]  |
| Why does humidity affect viruses? Posted: 02 May 2020 08:12 AM PDT "High Humidity Leads to Loss of Infectious Influenza Virus from Simulated Coughs" says a 2013 paper however it does not explain what the mechanism is. This may have important implications for SARS-CoV-2. EDIT: In response to the top (incorrect) comment (841 votes) by u/adaminc: Gravitational settling is an insignificant factor if we go by the the paper, which says... *settling can remove over 80% of airborne influenza 10 minutes after a cough and that RH increases the removal efficiency only slightly from 87% to 92% over the range of RHs* I did replyto that post but the Reddit algorithm meant my comment wasn't seen by many people so I have added it here in the original post.

| Why is it not possible to discover the location / direction of where the big bang started? Posted: 03 May 2020 07:30 AM PDT If, for example, using the balloon theory, could you not anchor certain points and measure the movement of objects/galaxies and compare the data, would you not eventually be able to discover the location or direction of where the matter is moving from / in / expanding towards to? Are we simply lacking the technology to do the measurements (if we got past the problem of red shifting for example) or is there scientific reasons we can not do it? [link] [comments]  |
| Is there a limit to how many different antibodies can a human body have? Posted: 03 May 2020 04:57 AM PDT |
| Will the Milky Way galaxy collapse inside its black hole at the center? Posted: 03 May 2020 06:43 AM PDT If I'm not mistaken, the galaxy is spinning and there's a black hole at the center. So will the arms of the galaxy eventually get swallowed by the black hole at the center? Is this how the Earth will end? Or will the sun run out of energy before that? [link] [comments]  |
| Posted: 03 May 2020 12:18 AM PDT Quite a few of my engineers are expressing skepticism for this project, and I totally get it. [link] [comments]  |
| How is the probability of false positives determined? Posted: 02 May 2020 11:09 PM PDT Dr. Birx has said that the covid tests are not a 100% sensitive or specific. She didn't say how accurate the tests are, but she gave a hypothetical example of a 99% accurate test and said that if 1% of the tested population actually has the disease, a positive test result would be correct 50% of the time and incorrect 50% of the time. How does that work? Is there a formula? Is there a name for this kind of probability modeling? [link] [comments]  |
| Has anything been discovered about viruses or the immune system because of COVID-19? Posted: 02 May 2020 04:29 PM PDT Has anything general been discovered or has everything we have learned been specific to this virus specifically? [link] [comments]  |

| Why is copper creep resistant, but also ductile? Posted: 02 May 2020 01:51 PM PDT This may be more due to me not quite understanding what creep is, but to my understanding, a metal that is ductile is a metal that can deform plastically but creep is a form of plastic deformation. How can copper be both creep resistant but also ductile? [link] [comments]  |
| What is the meaning of negative and positive current? Posted: 02 May 2020 10:10 AM PDT So I am wondering, positive current just means it is in the direction that positive charge would flow. Therefore it follows negative current would be in the direction that negative charge would flow. My question is, is the current negative because of the sign of the charge or because it flows in the opposite direction as positive? I know current is defined as dq/dt so it makes sense that dq would be negative with negative charges moving, but the charges could have had different names not involving arithmetic signs right? What is positive charge was red and negative charge was blue and we defined positive current as direction that red charge would move, then negative current couldn't be a result of the sign of the charge but rather the direction, right? Or maybe we only use a convention that allows for the sign on the charge to matter because the names of the charges were assigned that way? Perhaps the convention would be completely different if they were named red and blue? [link] [comments]  |
| How damaging can a earthquake be to a human not near any buildings/destroyable objects? Posted: 02 May 2020 10:43 PM PDT If a human was standing on a open field with no objects to be destroyed. How much damage could a centralized earthquake do the person. 7 magnitude for a general value if needed. [link] [comments]  |
| What is holding Remdesivir back from fully stopping COVID or any virus in general? Posted: 02 May 2020 10:38 PM PDT I know that the drug is a nucleoside analog that is supposed to, when added to the viral base sequence, change the sequence to code for the termination of viral replication once incorporated into the viral DNA, and once Polymerase and other Viral TFs try to transcribe it. Is the issue with the drug getting into the cell, or getting it into the virion? If the latter, is that why this spike protein is so important, to find an entryway into the virion? Also, what happens to that DNA once replication is terminated? Is it degraded, or does It still have potential to be expressed again? [link] [comments]  |
| Could a New Madrid fault line earthquake create a drop in elevation? Posted: 02 May 2020 01:33 PM PDT Could a big earthquake cause the area to sink and reverse the flow of the Mississippi and create a sea or bay of sorts? [link] [comments]  |
| Does caronavirus mutate between every person? Posted: 02 May 2020 07:23 PM PDT If we were able to fully sequence it on every person, would we be able to use to nearly perfectly trace the transmission path? [link] [comments]  |
