| 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:
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]  |

| Could you be killed by a single photon? Posted: 04 Aug 2020 07:28 AM PDT If a single photon has high enough energy, could it kill you? Is there a maximum limit to the energy of one photon? [link] [comments]  |

| Can fish spread deadly diseases, or are they common? Posted: 03 Aug 2020 05:01 PM PDT I always hear about birds and mammals spreading disease but what about fish? Is there any common disease or even rare ones? [link] [comments]  |
| How do plants with purple leaves photosynthesize? Posted: 03 Aug 2020 10:08 PM PDT How do plants/trees with purple leaves, or leaves that aren't green do photosynthesis? I thought they needed chlorophyll for that process. [link] [comments]  |
| How are we able to provide detailed maps of space? Posted: 04 Aug 2020 01:28 AM PDT I know that we can detect radio waves and get an idea of where the origin of the wave is located and what sent it, but how are our maps so accurate? How is it possible to see past the millions of stars to go so far as to see hundreds of other galaxies? For example how to we know about the cosmic web? [link] [comments]  |
| How were unbilical cords cut tens of thousands of years ago? Posted: 03 Aug 2020 04:15 AM PDT If umbilical cords need to be cut how were humans expected to cut them tens of thousands of years ago before the invention of tools (before the stone age)? Similarly I'm assuming apes and other mammals have umbilical cords aswell, so how do they deal with it in the wild? [link] [comments]  |
| How did humans get to Australia? Posted: 03 Aug 2020 01:23 PM PDT They got to the Americas from todays Russia during an Ice Age. But how do you get to Australia? The most obvious possibility would be boats but afaik Aborigines aren't and never were big sailors. I'm confused... did they learn how to build boats and then they unlearned it? Or am I wrong about Aborigines not being good sailors? [link] [comments]  |
| Posted: 03 Aug 2020 07:46 PM PDT We seemingly have done it/on the brink of doing it for polio and certain pestilences. Is it too big a job, or just not feasible? [link] [comments]  |
| Posted: 03 Aug 2020 06:44 AM PDT I assume that what we actually experience as smell is really just tiny particles interacting with your nose hairs, but is that correct? And why are smells so varied and unique? Does smelling work similarly to hearing where the tiny hairs send signals to the brain based on the pressure signal it receives? Do the sensory hairs in the nose receive chemical signals that they then convert to a nerve signal? I've thought a lot about this and always found it interesting how little I was taught in high school science classes about how your nose works compared to the eye, ears, even your tongue.

| Does every single neuron on your body respond to adenosine or is it some special receptors ? Posted: 03 Aug 2020 06:05 AM PDT So ive read about the current guinness world record for the most days stayed awake. the guy said that he has insomnia after the 12 days and 15 seconds of being awake so i was wondering is it like the situation of exposure to too much dopamine = less receptors? does it mean that too much exposure to adenosine somehow decreased the receptors ?

| Why do our muscles contract when we get electrocuted ? Posted: 03 Aug 2020 05:09 AM PDT |
| What's the smallest a stable flame could get? Posted: 03 Aug 2020 06:55 AM PDT Let's say you somehow got shrunk down to the size of an ant, could you still make a fireplace for yourself with an appropriate size? If yes, is there a point you'd no longer be able to do so? [link] [comments]  |
| What’s at the center of a Cosmic Super Attractor? Posted: 03 Aug 2020 09:02 AM PDT I recently learned about the cosmic web and our local knot-and-thread neighborhood, including the Virgo Super Cluster, the Great Attractor, etc. What I'm really interested in is the biggest attractor in our neck of the Universe, the Shapley Attractor. I realize the concentration of light at these points would be very bright from the high concentration of galaxies near the center, making it hard to observe anything, but do we have any best guesses about what the Shapley Attractor is or what lies at it's center?

| What are the “poisonous fumes” emitted by the NASA capsule that splashed down today? Posted: 02 Aug 2020 07:09 PM PDT I have read several articles that covered the splashdown of the capsule in the Gulf of Mexico today. All of the articles mention the group of boats that encircled the capsule after landing in the ocean, and they stated that the boats were endangering themselves, because there are "poisonous fumes" emitted by the capsule, and it would be very dangerous to get too close. However, none of the articles explained where the fumes came from, or gave any other details. What is the chemical makeup of the fumes? Were there similar fumes emitted by other space vehicles, like the space shuttle after re-entry? Are there poisonous chemicals getting released into the ocean from the capsule? [link] [comments]  |
| Why do areas directly on the equator tend to be so heavily forested? Posted: 03 Aug 2020 06:24 AM PDT I was looking around on google maps when I noticed that almost everywhere along the equator there are really dense forests (amazon, congo, SEA, etc.) And then usually deserts on either side of these greener areas. What causes this? [link] [comments]  |
| What makes sounds of the same frequency sound different to my ear? Posted: 03 Aug 2020 05:17 AM PDT If our ears pick up different frequencies and convert them to sounds in our brain, why, for example, would a C note played on a piano sound different than a C played on a guitar? I'm assuming these two notes would contain the same frequencies. [link] [comments]  |
