| AskScience Panel of Scientists XVIII Posted: 05 Feb 2018 04:54 AM 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]  |
| How effective are the black bars football players put under their eyes? Posted: 04 Feb 2018 03:24 PM PST I understand it helps with the light, the glare and the reflection from the lightspots, I was just wondering if someone had answers concerning the usefulness of the black lines football players put under their eyes.

| How do whales, the largest mammals on earth that inhabit the water, end up beached? Posted: 05 Feb 2018 05:59 AM PST I had posted this on r/explainlikeimfive and one user told me to post over here like the title says. Someone had suggested that they just end up swimming too close to shore and get pulled in by the current or that it could also be due to ongoing marine studies, such as the use of sonar, dredging, etc.What are some of the current theories/studies trying to prove as to why this happens?

| Why does Kosovo have so many more people than Montenegro? Posted: 05 Feb 2018 01:29 AM PST When you look at Kosovo and Montenegro on a map, they seem really similar in size (Montenegro is actually a bit larger, at 14,000 km2 to Kosovo's 11,000 km2). Yet Kosovo has about three times as many people (1.8 million compared to 600,000). Kosovo is almost as populous as neighbouring Macedonia, which is much larger in size. Furthermore, while both countries are mountainous, Montenegro has access to the sea (which is advantageous) whereas Kosovo is landlocked and appears to have fewer resources and fewer reasons to settle there. So, why do such similar neighbouring countries have radically different population? [link] [comments]  |
| How are expiration dates assigned to medicine? Posted: 05 Feb 2018 05:15 AM PST Most times the components in medicine (either pills or syrups) are chemicals. What do you take into account to set an expiration date? [link] [comments]  |
| Posted: 04 Feb 2018 09:28 PM PST I just saw this in an AskReddit thread where someone said that the morning after pill works to prevent ovulation and fertilization. This caught me a little off guard, so I wanted to ask about this here! I'm not in the US - I'm in South America. Although I eventually dropped out, I did go to med school for three years, and I distinctly remember my pharmacology professor and later an OBGYN preceptor during my first clinical clerkship saying that levonorgestrel has a higher chance of taking a post-fertilization MOA. I believe there was some study that pointed to that as well - scientists from Spain, I think? I'm trying to find something in English rather than Portuguese and the first thing I came across was this: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5102184/ For reference, emergency contraception is available without a prescription here in Brazil. Someone in class asked if it induces a miscarriage/acts as an abortive medication, and the professor started going in detail about how technically, there is a chance that the drug works to prevent a pregnancy that's already started (very early stage, though...). IIRC, the explanation given is that this particular EC "tricks" the body - it rapidly increases the progestogen levels that the body normally builds up after ovulation. This causes the endometrium lining of the uterus to thicken and then as the progestogen levels start to decline, the person who took the EC gets their period. They did say that the pre or post fertilization MOA depends on what stage of the menstrual cycle the woman taking it is in. It's funny that most of the web searches in Portuguese do mention the post-fertilization MOA. Now, when I searched for this in English, most information available (not in official research, more like Your Reproductive System 101) emphasized that this drug prevents ovulation and that it absolutely did not work the same as abortion pills. So...that got me curious, and I wanted to know what's the cause of this divergence in information. Thanks! [link] [comments]  |

| In a perfectly conductive wire, does information travel at the speed of light? Posted: 04 Feb 2018 10:25 PM PST Like when you press a button like a mouse click, would the information of the click travel to the computer chip at the speed of light, if the wire was perfectly conductive? Couldn't find a good answer online. Thanks. [link] [comments]  |
| What substances polluted the Earth in the 17th and 18th Century? Posted: 04 Feb 2018 09:44 PM PST Okay, so in the 20th and 21st century, there are a TON of substances that pollute the Earth, CFC, Carbon Monoxide and things like automobiles and industries and what not. What were the atmosphere degrading substances back when the world was not as advanced as it is now ? [link] [comments]  |
| Posted: 04 Feb 2018 01:14 PM PST I am very sorry for such a boring question, but I'm struggling to find why the Oxydizing symbol is the way it is. I need to explain what is happening in the image so I can seperate it from the Highly Flammable symbol. [link] [comments]  |

| Why do rotating black holes look so weird? Posted: 04 Feb 2018 01:28 PM PST So I found this website from ESA where you can play around with a black hole and the rotating black hole (Kerr black hole) looks so weird. Why does it have that shape? [link] [comments]  |

| How do internet cables and telephone poles transmit so much data all at once? Posted: 04 Feb 2018 08:07 PM PST I know that they send data in bits of electric pulses but I don't understand how they can transmit so many calls at once or how they can show so many people different sites at once without it being too much. I can't imagine people putting a whole new wire in just because you want an extra Ethernet connection or an extra phone line. [link] [comments]  |
| How are a non-planetary nebulas created? Posted: 04 Feb 2018 03:05 PM PST |
| How did differing chromosome numbers evolve? Posted: 04 Feb 2018 07:27 AM PST How could different chromosome numbers evolve in a species without an organism with a different chromosome count just dying because of that "mutation". [link] [comments]  |
| Posted: 04 Feb 2018 09:28 PM PST I'm asking because the Wikipedia source links to a 2008 Scientific American article that simply states the same fact with no other source to back it up. All searches for this study lead me in circles back to the same article. [link] [comments]  |
| How do the graphics on the super bowl field work? Posted: 04 Feb 2018 03:03 PM PST How are images and text displayed? Is the field like a giant green screen? [link] [comments]  |
