- AskScience AMA Series: Let's talk about genetic counseling! We are experts from Johns Hopkins Medicine here to answer your questions about genetic counseling, DNA tests, and the importance of family history when talking to your doctor - AMA!
- If Cacti are known for growing in the harshest of environments, Why don't we see them in non-harsh environments?
- What are the consequences of missing a full night of sleep, if you make up for it by sleeping more the next night?
- When a massive star crumbles into a neutron star, the protons and electrons of the atoms that make up the star combine to become neutrons. But since the electric charge of a proton and am electron is equally opposite, so is one proton fuse with one electron is enough to become a neutron?
- How does the 30mm A-10 warthog gun penetrate tanks, when a 105/120 mm tank gun has trouble doing that?
- How does marijuana farming impact soil health in comparison to a standard crop such as corn?
- How do babies use/learn language?
- Do other mammals (or animals in general) "lose their voice" like we do?
- Are radio waves affected by the dopler effect, Why don't I hear a distortion as I'm driving towards or away from a radio station?
- Human fingertips wrinkle in water to aid with grip. Are there any other examples of similar evolutionary traits in land based animals when they go into water, or water based animals when they come up onto land?
- Is there a known limit to the amount of horse power an internal combustion engine can produce given set units of air and gasoline?
- How long does it take for supplements like calcium or vitamin B to be absorbed?
- Are and how are DNA repair mechanisms in plant cells different than those in animal cells?
- What is the C3 convertase made of?
- Are fat cells lost when there is fat atrophy or do they just become smaller?
- Why are there so many citrus fruit hybrids?
- What's the deal with beer bellies?
- When a photon hits a mirror and goes from v=c to v=-c is there a moment when v=0? Does the mass of the photon decrease during this time?
- Is a solar system with breathable air within the interplanetary space possible?
- Why is there only one predominant variety of banana?
- Why is saline solution and not pure water used for storing contact lenses, washing eyes etc.?
- Have there been any species once believed to be two distinct species but later proven that one is the juvenile form of another?
| Posted: 08 Nov 2018 05:15 AM PST Hi Reddit, we are Natalie Beck, Katie Forster, Karen Raraigh, and Katie Fiallos. We are certified genetic counselors at Johns Hopkins Medicine with expertise across numerous specialties including prenatal, pediatric and adult genetics, cancer genetics, lab and research genetics as well as expertise in additional specialty disease clinics. We'll start answering questions at noon (ET, 17 UT). Ask us about what we do and how the genetic counseling process works!

| Posted: 07 Nov 2018 08:34 AM PST My scientific curiosity about this comes from the fact that I just traveled from the telescopes in the mountains of Chile all the way back to the US and I wasn't able to sleep a wink on any of the flights, perhaps maybe a 30-minute dose-off every now and then. I sit here, having to teach tomorrow, wondering if I should nap now, or just ride it out and get a healthy night's sleep tonight. I'm worried that sleeping now will screw me into not being able to fall asleep tonight. I did some of my own research on it, but I couldn't find much consensus other than "you'll be worse at doing stuff." I don't care if I'm tired throughout today, I'll be fine---I just want to know if missing a single night is actually detrimental to your long-term health. Edit: wow this blew up, thank you all for the great responses! Apologies if I can't respond to everyone, as I've been... well... sleeping. Ha. [link] [comments]  |

| How do babies use/learn language? Posted: 08 Nov 2018 07:15 AM PST I've always been fascinated by this: babies who can recognise their mother tongue and separate it from foreign languages they haven't heard often. How do babies start learning a language (and why is it so difficult for adults to learn one), what makes them prefer their mother tongue and how do they interpret what adults are telling them?

| Posted: 08 Nov 2018 04:38 AM PST Obviously if you increase the volume of air and fuel into the engine, the engine will produce more power via forced induction or through increasing the size or number of combustion chambers, but if given a set volume of air and fuel, is there an upper limit to the amount of horse power an engine can produce using real-world physics? I'm hoping there's an answer like "In a 2.5l engine, one gallon of 89 octane gasoline burned per minute cannot produce more than 400hp" I'm specifically thinking about consumer-grade gasoline commonly found at gas stations, not special blends like E85 or racing fuels.

| How long does it take for supplements like calcium or vitamin B to be absorbed? Posted: 07 Nov 2018 06:03 PM PST I want to know how long it takes for a supplement to be absorbed into your body and make a difference in someone's body. For example, if someone just discovered they were anemic and we're taking an iron supplement, how long would it take for their iron levels to go back to normal? [link] [comments]  |

| What is the C3 convertase made of? Posted: 08 Nov 2018 07:25 AM PST Is the C3 convertase in the classic complement pathway a mixture of C4bC2b or C4bC2a? Is 2a the previous name for 2b and that's why some refrences say it's 2a? [link] [comments]  |

| Why are there so many citrus fruit hybrids? Posted: 07 Nov 2018 05:43 PM PST Many of the fruits belonging to the genus Citrus are hybrids... why is that so? What makes then so easy to hybridise than other genera? And how is it possible that their hybrids can reproduce? [link] [comments]  |
| What's the deal with beer bellies? Posted: 07 Nov 2018 05:31 PM PST There's definitely a distinctly round belly that is often associated with drinking lots of beer, but why? I know you can't work out certain parts of your body to target your weight loss, I assume you can't target your weight gain either. Maybe I'm just not very observant, but I don't know if I've ever seen a woman with a beer belly. Is this an exclusively male thing? [link] [comments]  |

| Is a solar system with breathable air within the interplanetary space possible? Posted: 08 Nov 2018 12:29 AM PST Okay, i watched some 80ies cartoons, and now I have strange questions. Is it possible to have a solar system which has breathable air, not only on planets which can hold an atmosphere, but also in the interplanetary space between them? Could something like that work without the air dispersing, or the whole system getting "too heavy" etc. Any Ideas? [link] [comments]  |
| Why is there only one predominant variety of banana? Posted: 07 Nov 2018 07:42 PM PST There are dozens of varieties of apples. What's different about banana cultivation? [link] [comments]  |
| Why is saline solution and not pure water used for storing contact lenses, washing eyes etc.? Posted: 07 Nov 2018 07:36 PM PST |
| Posted: 07 Nov 2018 05:17 PM PST I was reading an article about the book "All Yesterdays" and the appendix includes an "All Todays" section where the authors consider how future paleontologists might interpret the fossil record of today. One thing that stood out was that tadpoles might be construed as some sort of fish. Have any species been classified as distinct until advances in science proved that they were different stages of the same animal's life? [link] [comments]  |
