| 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]  |

| Posted: 24 Jan 2020 09:47 AM PST The new coronavirus is apparently related to SARS. I remember a big fuss and it spreading to Canada, but the CDC says no cases have been reported worldwide since 2004. So how was it eradicated? Did they actually manage to find and quarantine every single one of the thousands of people infected? That doesn't sound plausible. Why didn't it keep spreading? [link] [comments]  |
| When Betelgeuse goes nova, why will the neutrinos arrive first, before photons? Posted: 24 Jan 2020 07:44 AM PST Since both travel at the speed of light, one would naively expect them to arrive simultaneously. do the processes which produce then occur at different times, or does something about traveling through interstellar space "slow down" the photons? EDIT: Duh, neutrinos are not massless particles that travel at the speed of light. Still fast enough & with enough of a head start to stay ahead of the photons over 600 light years though.

| What happens when a planet falls into a star? Posted: 24 Jan 2020 03:00 PM PST Is this possible? Or would a planet be destroyed by the heat and solar radiation before it got to the surface of a star? [link] [comments]  |
| Is Betelgeuse changing in ways other than brightness that might indicate a supernova is imminent? Posted: 24 Jan 2020 08:57 AM PST The news is all a-twitter about the possibility that the current dimming of Betelgeuse might be leading to a supernova soon. But dimness is the only thing I've seen reported as indicator of a possible upcoming supernova. Are there other observable features that might theoretically indicate an imminent supernova, and are we seeing any of them? For example, has its spectrum been changing recently? Would we expect that a star that is about to go supernova would undergo a spectral shift as it runs out of its primary fuel? Or would the photons that might show a shift be too deep within the star for us to observe before the star explodes? [link] [comments]  |
| How do pressure regulators work? Posted: 24 Jan 2020 01:40 PM PST I'm specifically thinking of pressure regulators for gasses, like for CO2 in a paintball marker. My understanding is that as long as the source pressure is greater than the desired output pressure, the regulator will always output the desired pressure; for example, if the gas reservoir starts at 2000 psi, the regulator will deliver 800 psi, and the reservoir empties, if it's at 1000 psi, the regulator will still deliver 800 psi. If that understanding is correct, how does the regulator deliver the same output while the input pressure changes? It seems like the output pressure would just be a linear function of the input pressure. Also, does a pressure regulator for liquids work the same way as ones for air? [link] [comments]  |
| How spins with relativity explains magnetism? Posted: 24 Jan 2020 10:25 AM PST I've learned that electric fields and magnetic fields can be join into one phenomena using relativistic theory, the explanation was pretty good for magnetic fields caused by electric current. But how can I explain using relativism the fact that spins cause a magnetic field ? In a lot of posts people explain this saying that electrons can be seen as charged balls spinning so in the end is like a closed loop of electrical current but I know that this model is wrong because the velocity of this charged ball will exceed c, so: Is there some way to connect spin and magnetism using relativism or we have to asume that spin is just a property and magnetism which spin causes is also another property with no deep explanation?

| Since when did organisms have the ability to "think"? Posted: 24 Jan 2020 04:19 AM PST |
| How are new vaccines "created"? Posted: 24 Jan 2020 02:08 AM PST EDIT: thx for the replies sofar :) I was wondering about it because of the outbreak in china [link] [comments]  |
| How deadly are human viruses such as common cold to other animals? Posted: 23 Jan 2020 03:31 PM PST there were many case where viruses that are not that deadly to animals jump to humans and become deadly. (bird flu, coronaviruses) Are there any documented cases where viruses is not as deadly to human become deadly to other animals? [link] [comments]  |
| Posted: 23 Jan 2020 02:43 PM PST Are they related some way or another? Are they simply from the same area? [link] [comments]  |
| Which Chromosomes Do Polygenic Disorders Affect? Posted: 23 Jan 2020 05:28 PM PST I am assuming polygenic disorders affect all the autosomal chromosomes and was wondering whether or not it affects the sex chromosomes? [link] [comments]  |
