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. submitted by /u/NaughtyFred [link] [comments]

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? 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... submitted by /u/smallwhales [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? submitted by /u/IndependentGuy [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. submitted by /u/thelastknowngod [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? submitted by /u/corrado33 [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.

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?

How does my computer precisely know what time it is? Posted: 12 Dec 2018 04:47 PM PST It seems that even if a global server that is deemed the correct time sent this time to my computer, given latency and network delays, my computer would be working off the old time, without knowing how much to adjust for this delay. I realize you could easily calculate the round trip delay by feeding this same time back to the original computer, and say half it, but this doesn't seem very precise given the up and down legs could have different latencies. ​ I realize the total variance wouldn't be huge, but still significant when accuracy matters for things like GPS, MLAT calculations, etc. ​ Enlighten me, please. submitted by /u/jbbwa [link] [comments]

Can a conductor "saturate" in the presence of a strong electric field and become nonconductive? Posted: 12 Dec 2018 09:28 AM PST It's my understanding that there can be no net electric field inside a conductor. That if a conductor is placed in an electric field, electrons will migrate in the positive direction until the electric field generated by charge displacement cancels the externally applied field. Is it possible to apply an electric field so intense that all electrons have moved to their limits without canceling the external field? If so, does the conductor no longer conduct? submitted by /u/NewRelm [link] [comments]

Does alcohol type has any affect on cloud chamber work? Posted: 12 Dec 2018 02:55 PM PST Hello everybody. I'm trying to make myself working cloud chamber (simple scheme: https://imgur.com/a/5mLtIyI). There are 3 wooden walls, front wall is glass. Top is also wooden, with 2 large sponges attached. Bottom is from thick sheet metal which is sealed with silicone to wooden and glass walls. I tried to experiment with this chamber, I raised the temperature inside with heat gun, then heated sponges and soaked them with ethanol. And closed the lid letting alcohol to evaporate inside the chamber. Then I just placed upper part (box), on dry ice in bottom container lined with styrofoam. I waited a few minutes, but nothing happened. I just saw cloud of, what i presume was just alcohol vapor. But I did't see any traces of particles. And I can't figure out what am I doing wrong. I saw somewhere, that with cloud chamber I should use isoprophylic alcohol, not ethanol. Could this be true? Or maybe it could rather be matter of tightness of chamber, or too high/low concentration of alcohol vapors? submitted by /u/Shedog [link] [comments]

Why does the order parameter of nematic liquids become zero for isotropic liquids? Posted: 12 Dec 2018 02:15 AM PST Hello The order parameter for nematic liquids ( liquid crystals) is S = 1/2 <3cos²q-1> according to multiple sources. q being the average angle between the molecular axis and the directional axis of the liquid. I get that for a perfectly ordered liquid q = 0 ( all molecules point in the direction of the directional axis), then you get 1/2*(3-1) = 1. Which is an expected outcome, as S = 1 for perfectly ordered liquids. However, the sources say that for an unordered liquid S becomes zero. Doing some maths reveals that the average angle would then be about 55°. Why would a liquid with an average of angle of 55° be 'perfectly unordered' but a liquid with an average angle of 50° not? So in short: why would S become zero for isotropic liquids? Thank you! submitted by /u/lolspek [link] [comments]

What portion of long term treatment resistant depression patients never really get better? Posted: 11 Dec 2018 07:46 PM PST https://www.webmd.com/depression/guide/treatment-resistant-depression-what-is-treatment-resistant-depression "Living With Treatment-Resistant Depression Life with depression is hard, but treatment-resistant depression can be especially brutal. When one treatment after another doesn't help, you can lose hope that you'll ever feel better. All your efforts -- the doctor's visits, the medication trials, the therapy sessions -- might seem like a waste. But they haven't been a waste. Arriving at the right treatment for depression can take time. It can take some trial and error. Look at it this way: if you try a particular treatment and it doesn't help, you're that much closer to finding the one that will make you feel better. Whatever you do, don't settle. Don't give up and accept the symptoms of depression. Remember, the longer a depression goes on, the harder it may be to treat. Go back to your doctor and see if there's something else you can try. There are so many good treatments for depression out there. You just need to find the right one for you." This seems to imply that all cases of depression can eventually be effectively treated. That seems dubious to me. What portion of long term treatment resistant depression patients never really get better? What portion just keep on trying different different meds until they die of natural causes? What portion choose to end their lives? What portion eventually choose to discontinue treatment, but continue to suffer? What portion discontinue treatment, but feel better? Any other possibilities I'm missing? How well can this even be measured and known? submitted by /u/benjaminikuta [link] [comments]

Where in the night sky is Voyager 1 headed, in the long term? Posted: 11 Dec 2018 04:30 PM PST From this skypath of Voyager 1's trajectory, generated from NASA data, it looks like Voyager 1's location in the night sky is asymptotically approaching a point somewhere in the triangle formed by Rasalhague (α Ophiuchi), Rasalgethi (α Herculis), and HIP 84671 (e Ophiuchi). Will Voyager keep approaching this point indefinitely? Or are there any long-term effects that will cause its position in the sky to drift over the coming hundreds or thousands of years--a time scale long enough that these effects haven't been observed yet, but short enough that the stars will stay in roughly the same places? submitted by /u/dpitch40 [link] [comments]

How can electric devices and other sources of rather large voltages be lethal in water if the flow of electricity follows the path of least resistance? Posted: 11 Dec 2018 03:12 PM PST So after thinking about this for a while i thought i should ask why, say 230V common electricity network (atleast in Europe it is) can electrocute someone to death in a bathtub even though both of the electrodes are very close to each other without a human in between them? Shouldn't the flow of electrons just pass through the path that has the least resistance (i would believe it would be directly between the electrodes in a homogenous electrolyte) without harming the person in the bathtub? submitted by /u/Ollemeister_ [link] [comments]

Not all cigarette-naive individuals have the same experiences upon smoking. What role do MAOIs play in addiction and pleasure of cigarettes for different brains, and can we use this as a diagnostic tool for distinguishing between otherwise similar disorders and to guide prescriptions of medication? Posted: 12 Dec 2018 05:22 AM PST Some people become addicted, while others don't. Some people experience strong headspins and nausea during their first few cigarettes, while others don't. While these could be mostly differences in mindset, lifestyle or puff speed, it's well established that there's variation in brain structures and our specific chemistries, such as alcohol metabolism or different responses to prescription medications. The likelihood of an individual adopting a new addiction is increased through down-regulation of brain regions from existing addictions and other aspects of lifestyle such as stress and the absence of physical activity, social interaction, etc. While some demographics are more prone to developing a substance use disorder (such as those with borderline personality disorder and adolescents) , they also tend to have the traits mentioned above which prime them for adopting addictions. Given that nicotine has it's addictiveness enhanced by MAOIs, and SSRIs like bupropion are used as smoking cessations, could we administer cigarettes to patients to figure out which anti-depressents may work, or to distinguish between disorders with similar behaviours but very different chemistries? For instance in distinguishing whether someone has OCD or ADHD, hypothyroidism or chronic fatigue syndrome, cyclothymia vs seasonal affective disorder, etc. submitted by /u/ThrowawayBrisvegas [link] [comments]
