- I saw a video of someone breathing in a rag of chloroform and getting instantly knocked out. I don’t think that’s real, but it made me curious. How does chloroform work? And what exactly does it do?
- How does a muscle attach to a tendon and how does a tendon attach to a bone?
- How do water molecules on opposite spokes of a particular flake "know" to reproduce a specific pattern?
- When groups of animals that use echolocation do so, how are they able to differentiate which sound was theirs? Can a dolphin that’s in the middle of a group pick up on the sound of another dolphin that’s on the outer edge of said group and know exactly what the other dolphin is seeing?
- Are nebulae and gas clouds in space dense enough that sound could travel through them?
- Because CO doesn't ever unbind from hemoglobin until the red blood cell dies, wouldn't a blood transfusion be an effective treatment for people who have CO poisoning?
- Are there limits (low or high) to the frequencies that lasers can emit?
- Do radio receivers draw some power from the radio waves they receive?
- Do the effects of dyslexia change depending on the native language of the affected person?
- What are the other differences besides temperature (boiling points etc.) between water and oil that makes water 'boil' food and oil fry?
- Does an electron jump back down from it's excited state to it's initial state spontaneously or is there a definite interval involved before it jumps back down?
- If all it takes is moving charges to create a photon does this mean that simply waving a statically charged comb back and forth (or in a circle) is generating photons?
- How were the first atomic clocks calibrated without an existing frequency reference that was fast and accurate enough to measure the frequency stability?
- We know antennas transmit by oscillating between positively charged and negatively charged rapidly like a sine wave. But what happens if you were to rapidly force a negative charge into an antenna and then discharge it to a neutral and then do it again? What kind of EM wave would that create?
- Are the signals sent by nerves in our body "digital" or "analog"?
- What happens when two batteries are in parallel?
- Statistically speaking, how common are sex chromosome variations (eg. XXX, XXY) in the general population?
- Why does greater Mongolia have so much rare earth metals?
- Are String Theory "Fuzzballs" and Loop Quantum Gravity "Plank Stars" the same thing?
- Why do blue stars tend to reside closer to the galactic plane?
- How does HIV resistance work? Is it similar to antibiotic resistance?
- How do scientist knew back in the days when chemical elements were discovered if you had a mono constituent substance?
- How do Biologists Determine what “Normal” is for a New Species?

| How does a muscle attach to a tendon and how does a tendon attach to a bone? Posted: 13 Dec 2018 08:24 AM PST Is it physical structures like microscopic hooks/anchors? Some kind of biological "adhesive"? Edit: Question answered. Several very knowledgeable people have done a great job of explaining that there is no "attachment" rather there is no end between bone/tendon and muscle, they all just merge into each other. Which is pretty amazing when you think about it. Thanks everyone. [link] [comments]  |

| Posted: 13 Dec 2018 09:24 AM PST I was watching Blue Planet and being underwater hearing all of the clicks and whistles the dolphins were using made me wonder if all of the dolphins heard each other. Does one big pod(?) of dolphins make a huge beacon of sonar that allows each dolphin in the group to see what the others are seeing? If not and it's comparable to "how can you tell when your mother or sister calls you?", is it the frequency that each individual dolphin uses to determine which sound was theirs? Can they only hear one frequency at a time? If not, underwater must be so loud... [link] [comments]  |
| Are nebulae and gas clouds in space dense enough that sound could travel through them? Posted: 14 Dec 2018 06:47 AM PST I'm basically wondering if in a nebulae you could hear stars being created [link] [comments]  |

| Do radio receivers draw some power from the radio waves they receive? Posted: 14 Dec 2018 01:30 AM PST I was thinking about this the other day. When I turn on my car radio, does it actually draw some power from the EM field, weakening it? Can this affect other receivers nearby, making the signal weaker for them? [link] [comments]  |
| Do the effects of dyslexia change depending on the native language of the affected person? Posted: 13 Dec 2018 06:30 AM PST I was wondering specifically about languages with logographic/syllabic alphabets like Chinese, Japanese, or Korean. The structure of Hangul in particular seems like it would be harder to misspell or misread a character since they are (sorta) like an instruction manual for how to pronounce each individual syllable. I don't speak any of those languages fluently though so I could be way off base here. [link] [comments]  |

| Are the signals sent by nerves in our body "digital" or "analog"? Posted: 13 Dec 2018 11:45 AM PST I've wondered this for a while. Are the signals sent by nerves in our body "digital" meaning that they are simply on or off, or analog, sending an increased signal when more pressure or heat is applied? If they were digital they'd send "more signal" by simply more nerves being activated. If they're analog... then what do they look like? [link] [comments]  |
| What happens when two batteries are in parallel? Posted: 13 Dec 2018 03:24 PM PST |
| Posted: 13 Dec 2018 05:02 AM PST For example, in a group of 1000 people how many would have chromosomes other than XX or XY? [link] [comments]  |
| Why does greater Mongolia have so much rare earth metals? Posted: 13 Dec 2018 09:55 AM PST Most rare earths (Cerium, Gadolinium, etc.) are mined in Inner Mongolia, and Mongolia proper has a lot of it too. What's so special about the historic Mongol lands that gives them so much of these useful elements? [link] [comments]  |
| Are String Theory "Fuzzballs" and Loop Quantum Gravity "Plank Stars" the same thing? Posted: 13 Dec 2018 12:33 PM PST If I understand correctly, and I probably don't, they both hypothesize that at and inside the event horizon there is some sort of super dense "material", strings in ST and I don't know what in LQG. Both seem to solve the information paradox (inside the black hole there is no infinite collapse to a singularity, so information is not lost) and both stay black holes for any far away observer. Are Fuzzballs == Plank Stars? [link] [comments]  |
| Why do blue stars tend to reside closer to the galactic plane? Posted: 13 Dec 2018 10:21 AM PST I was recently on the 1000,000 stars site and they showed how blue stars tend to reside closer to the galactic plane. Why is that? [link] [comments]  |
| How does HIV resistance work? Is it similar to antibiotic resistance? Posted: 13 Dec 2018 09:15 AM PST In practical terms, if once a type of medicine no longer works against the pathogen, and you change your medicine, and the pathogen develops a new resistance again, and so on... Will it at some point become vulnerable again to your first medicine? If it's possible to develop resistance to multiple medicines, how is the new pathogen not vulnerable in ways it was not vulnerable before? Isn't picking up an advantageous trait also confer a potential weakness we can exploit? How does evolution and natural selection play out here? [link] [comments]  |
