AskScience Panel of Scientists XXIII Posted: 23 Jul 2020 01:31 PM PDT 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: Are studying for at least an MSc. or equivalent degree in the sciences, AND, Are able to communicate your knowledge of your field at a level accessible to various audiences. Instructions for formatting your panelist application: Choose exactly one general field from the side-bar (Physics, Engineering, Social Sciences, etc.). State your specific field in one word or phrase (Neuropathology, Quantum Chemistry, etc.) Succinctly describe your particular area of research in a few words (carbon nanotube dielectric properties, myelin sheath degradation in Parkinsons patients, etc.) Give us a brief synopsis of your education: are you a research scientist for three decades, or a first-year Ph.D. student? Provide links to comments you've made in AskScience which you feel are indicative of your scholarship. Applications will not be approved without several comments made in /r/AskScience itself. 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: Username: /u/foretopsail General field: Anthropology Specific field: Maritime Archaeology Particular areas of research include historical archaeology, archaeometry, and ship construction. Education: MA in archaeology, researcher for several years. Comments: 1, 2, 3, 4. 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. submitted by /u/AskScienceModerator [link] [comments]

Do bath salts actually have any proven beneficial effects (e.g. on eczema), and is there any real difference between using Dead Sea salt VS Himalayan salt VS Epsom salt? Posted: 24 Jul 2020 10:47 AM PDT There is so much sales hype online I cannot find any scientific information. Thank you in advance! submitted by /u/HerbziKal [link] [comments]

Why don’t we have vaccines for all Herpes Viruses? Posted: 23 Jul 2020 10:10 AM PDT Ok so I hope I don't sound like a complete idiot, keep in mind I have very little medical knowledge. So we have vaccines for shingles and chicken pox, which are herpes viruses. However we don't have a vaccine for Cold sores, Genital Herpes, or Mononucleosis (also a herpes virus). Why is this? I know they are obviously different mutations but they all stem from the same viral tree. Is this something that the medical community is working on or is it a lost cause to find an umbrella Herpes vaccine? submitted by /u/BlissfullyOrbital [link] [comments]

Is there any difference between an immunity achieved by recovering from a virus and immunity achieved by vaccination? Posted: 23 Jul 2020 11:21 AM PDT submitted by /u/KnowOneTwoEat [link] [comments]

Why can't you get the HPV (gardisal) vaccine after the age of 26? Posted: 23 Jul 2020 06:52 PM PDT The question came up when seeing a family friend die of cancer. Tried looking it up and all I can find is that it's just, "not recommended". Does anyone have an in depth explanation to it? submitted by /u/annettelynnn [link] [comments]

Even with a vaccine, is it possible for a vaccinated person to carry a disease and pass it to someone unvaccinated? Posted: 23 Jul 2020 08:42 PM PDT If person A gets vaccinated against disease Z, can they still carry disease Z and pass it to person B who isn't vaccinated? I would think that depending on how long the virus is able to not be fought off or die out that it's still possible. That would make sense. You could have it but your body fights it while it could be passed to someone else. However, I'm not sure if I'm correct in thinking or even how to search this question. submitted by /u/slooksterpsv [link] [comments]

Could a disease/virus only be fatal to adults? Posted: 24 Jul 2020 07:44 AM PDT Pretty stupid question honestly haha but I've got a story idea for a script and the story necessitates that the world's adults have died to a mysterious disease/virus/sickness and only children live on earth. I don't know much about diseases/viruses and its effect on the human body. But is there some way of motivating that a disease/virus would be fatal only to adults? Hypothetically. It needs to be sound enough that you'd buy it if it was the context for a movie. submitted by /u/Vogsid [link] [comments]

How can DNA code for instinctive behaviours such as building nests, recognising preys, finding the mother's breast...? Posted: 23 Jul 2020 06:05 AM PDT Or how can DNA code for a brain with basic programmed behaviours? submitted by /u/RealTourelle11 [link] [comments]

Can smallpox reappear through doing another jump from animal (rodent, cow, etc) to human? Posted: 24 Jul 2020 03:53 AM PDT submitted by /u/a_is_for_a [link] [comments]

Is it possible to determine an extinct, venomous animal's toxicity? Posted: 23 Jul 2020 06:39 PM PDT I posted this question already but I'm sure if there was an error or not... submitted by /u/CantFindWatImlookin4 [link] [comments]

Why does ionizing radiation cause cancer but not lower frequency radiation? Posted: 23 Jul 2020 05:18 PM PDT My understanding is that radiation with photon energies above a certain amount are able to liberate electrons from their orbits, potentially causing damage to dna when the bonds reform in inappropriate ways. However, what if you were were to say, shine an intense source of visible light on a tiny spot of skin. Couldn't atoms be ionized by many lower energy photons striking the same atom? submitted by /u/Tasty_Peach5791 [link] [comments]

What is the “stomach virus” and why is there no cure for it? Posted: 24 Jul 2020 01:27 AM PDT The stomach virus, or stomach flu, is something that just comes and goes when it pleases and there's nothing you can do except wait it out. Is there any particular reason that we don't have a cure for it? submitted by /u/ThatDudeOverHeree [link] [comments]

I have read online that some fabrics have antimicrobial properties. Is this true? How does this work? Posted: 23 Jul 2020 06:21 AM PDT I know some metals have antimicrobial properties, so I can see how in theory fabric with metal weaved in could have antimicrobial properties. But I see stuff saying that fabric made from bamboo and hemp also have antimicrobial properties. Is this true at all? submitted by /u/PeasantFood [link] [comments]

Why is it impossible for a perfect sphere to have precession, and why does the shape of the Earth allow it to have precession? Posted: 23 Jul 2020 11:59 PM PDT I understand that the Precession of the Equinoxes causes Earth's axis of rotation to rotate perpendicularly to the ecliptic plane, but I am having a hard time understanding what type of forces cause the precession to happen. From my understanding, the Earth has a longer diameter in the equatorial plane than across the poles due to the rotation of the Earth. If the Earth was a perfect sphere, there would be no precession. The moon and sun interact with this widening through gravity and this creates a torque on the Earth. How exactly does this widening allow to Earth to precess compared to a perfect sphere? Which direction is the torque on the Earth? submitted by /u/AIDSinmycock [link] [comments]

Why can I bend fiber optics? Posted: 23 Jul 2020 04:22 PM PDT How come glass, being very easy to shatter, can be extremely flexible when drawn out into fibers? The only explanation I've gotten is because it's thin, but what is the reasoning behind that? submitted by /u/joshuamunson [link] [comments]

How come heavier particles have a higher Svedberg coefficient? Posted: 23 Jul 2020 07:33 PM PDT I understand that Svedberg is a unit of time (10^-13 seconds) indicating the amount of time it takes for a molecule (such as ribosomes) to settle but what I don't understand is how come heavier particles that settle faster have a higher Svedberg coefficient. If it settles faster, wouldn't that mean it would have a lower Svedberg coefficient? submitted by /u/roll-ricked [link] [comments]

The Prime Meridian goes through Africa so it also goes through the other side of the world? Posted: 23 Jul 2020 01:19 PM PDT Hi guys, Pretty much the title. Logically speaking, the Prime Meridian cuts the world in half vertically. But all the maps I see pretty much only show one line (through London and West Africa), and if there's only one line, does it mean the maps just don't draw the other line? Shouldn't there be another line across the globe from Africa, that goes vertically through Australia or something? Maybe I'm just having trouble visualising a flat map as a globe, but if you guys can help me out, thank you very much! https://www.thoughtco.com/thmb/4Q7jZbyDMtYcoBFKkrBeaWGZByU=/768x0/filters:no_upscale():max_bytes(150000):strip_icc():format(webp)/0-N-0-W-58d4164b5f9b58468375555d.jpg:max_bytes(150000):strip_icc():format(webp)/0-N-0-W-58d4164b5f9b58468375555d.jpg) submitted by /u/AncientCupcakeFever [link] [comments]

Mechanism of Renal Toxicity of Thiobutabarbital? Posted: 23 Jul 2020 06:53 AM PDT Thiobutabarbital was withdrawn from the German market in 1993 due to renal toxicity. I am trying to find the mechanism of renal toxicity of thiobutabarbital but i am struggling to do so. The only thing I have been able to find is a study in which thiobutabarbital-anaesthetised rats experienced significant diuresis which could be related to direct inhibition of ADH-dependent and/or independent renal fluid reabsorption. Same article says that thiobutabarbital inhibited proximal tubular reabsorption of Na+ in rats. I can't find an article that clearly states the mechanism of toxicity that was responsible for its withdrawal from the german market. Does anyone have any knowledge in this area? submitted by /u/Smol_Lemon [link] [comments]
