| AskScience Panel of Scientists XV Posted: 03 Aug 2016 10:55 AM 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]  |
| Posted: 04 Aug 2016 04:10 AM PDT I am out fishing and there are guys with lights that they use to light up the water in the back of the boat when it is dark out so they can see the fish, but all of the lights are either blue or more commonly green. I know from my stage crew days that blue is very hard to produce well, and that the human eye is most adept to see green, and when I did my scuba class they had a chart showing the depths that colors start to fade. This got me thinking however, why does blue light penetrate further than red light in water, shouldn't the same properties of Rayleigh scattering apply? [link] [comments]  |

| With an estimated 1,000,000 nematode species, what distinguishes them all? Posted: 03 Aug 2016 06:28 PM PDT I was on a Wikipedia safari, and read that there are 25,000 known nematode species, and 1,000,000 estimated total species. I'm wondering what could possibly distinguish between 1,000,000 variations of a little worm. Could someone explain the minimal distinguishing characteristics of a species of nematode?

| Posted: 04 Aug 2016 07:27 AM PDT Or does it have to do with the weak force? I've taken a few courses on QM so don't hold back! [link] [comments]  |
| What specifically causes neutrinos to oscillate flavor? Posted: 04 Aug 2016 07:44 AM PDT What special properties does it have that say and electron or quark don't have. From what I've been told, the necessary flavor and mass transformations don't commute and so they aren't simultaneous eigenstates, but why is this needed in the grander scheme? [link] [comments]  |
| How do all the power plants on the grid ensure that their output AC is in-sync with the grid's?. Posted: 03 Aug 2016 10:59 AM PDT If I plug in my laptop, for instance, into the wall here in the U.S., it will be charged by a 60 hz AC current. Presumably, multiple power plants are responsible for supplying this current at 60 hz. How do the designers of the grid ensure that all of these gigantic powerplants are perfectly in sync? What happens if one or more falls out of sync? Could the current become wonky and break a bunch of people's electronics? Thanks in advance! [link] [comments]  |

| What happens when opposite magnetic poles meet? Posted: 03 Aug 2016 05:32 PM PDT There's a gif in r/oddlysatisfying of a n/s magnet in a container of iron filings in some kind of solution. The filings aren't attracted to the center. What's happening? [link] [comments]  |
| Do dreams unfold procedurally or are they 'pre-written'? Posted: 03 Aug 2016 10:07 AM PDT I had a dream once that had a banging plot twist, which leads me to wonder if they might be predetermined in some way at the start of a dream. Is this possible? [link] [comments]  |
| So I read that rotating black holes have ring singularities. Can you pass through the ring? Posted: 03 Aug 2016 02:23 PM PDT What would happen if you had a rotating black hole and you fell down through the north or south pole? Would you oscillate through the ring and eventually settle down in the middle of it? Wouldn't that contradict orbital motion? If you fall from height x and you pass through the gravitational center undisturbed, you'd end up at height x again on the other side, right? [link] [comments]  |
| What's with all the water in that recent sinkhole gif? Posted: 03 Aug 2016 10:53 AM PDT
Watching that clip over and over, I just...like my brain can't really grasp a sinkhole with thrashing waves just opening up in a backyard like that. [link] [comments]  |
| What makes clownfish "immune" to anemones? Posted: 03 Aug 2016 11:10 AM PDT |
| Why don't electrons and neutrinos have smaller components? Posted: 03 Aug 2016 07:45 PM PDT As I understand it, above the electroweak unification energy, it becomes clear that electrons and neutrinos become two states of the same spin 1/2 particle with weak hypercharge -1 and weak isospin ±1/2 Quarks on the other hand look different independently, but when you add them up as protons and neutrons, they become spin 1/2 particles whose hypercharges add up to +1 and whose weak isospins add up to ±1/2 Under electroweak symmetry, they seem to mirror each other, but leptons are elementary and baryons are not. Why is this? Is it possible that leptons have their own components that are even more tightly bound? [link] [comments]  |
| Why does delta x * delta p >= h/4pi? Posted: 03 Aug 2016 03:37 PM PDT This is the math behind Heisenberg's Uncertainty Principle but what is the logic behind the right side of the equation? Why does delta x * delta p have to be greater than or equal to h/4pi? [link] [comments]  |
| How close are we to actually understanding what consciousness is and how it formed? Posted: 03 Aug 2016 08:17 AM PDT With what seems like advancements of our knowledge of the human brain being made nearly every week, I would assume that we are relatively close to understanding what consciousness is and how it formed. So, with all of this new information at scientists disposal, how close are we to understanding consciousness? [link] [comments]  |
| Do we lose our ability to remember dreams as we get older? If so, why? Posted: 03 Aug 2016 10:39 AM PDT |
| How do cancerous cells decompose? Posted: 03 Aug 2016 05:58 PM PDT Random on the toilet thought but my family's old dog passed away from cancer and was buried in the garden and I was wondering does the cancerous tissue decompose in the same way that healthy tissue does and does the fact that it is cancerous effect the bacteria that is decomposing it. Thanks [link] [comments]  |
| Does wood harden if it's underwater? Posted: 03 Aug 2016 11:58 AM PDT I've watched a few documentaries and read a few articles about the founding of Venice and one thing that they all mention, is that the Venetians used wooden beams as supports due to the lack of a solid foundation. They would drive these beams into the water and the soft soil until they hit bedrock and, according to these (secondary) sources, the wood overtime hardens instead of rotting as (I assume) the wood remains underwater and isn't exposed to the air. Is this true? And if so, what is happening to the wood to make it 'harden'? [link] [comments]  |
