Hi everybody I'm currently programming a Windows Phone app that should allow people to record their movement during sleep and derive estimated sleep phases from those values. Does someone have knowledge about how movement changes with different sleep phases? My guess now is that both, intensity and frequency of movement decrease with deeper sleep phases. I also think that frequency may be more accurate, i.e. in a REM phase, there is almost no movement of the whole body. What do you think? Does someone know good literature to that? Cheers, Bill

When training your muscles for strength, does motor unit recruitment increase in the way that the neurons fire more efficiently and produce greater contractile strength, or does the amount of motor neurons increase in the muscle? Or both? Or neither? Also, this is taken off medscape.com: -"Increasing the number of active motor units (ie, spatial recruitment)" Do they mean there are motor neurons in the vicinity of the muscle that are "dormant" or does the actual amount increase? Also, "As a general rule, motor units are recruited in order of their size. When the muscle is activated initially, the first motor units to fire are small in size and weak in the d…

I have had dreams while being awake. I need help, I have looked on the internet I can's really find anything that pertains to my experiences. On more than one occasion, I will be wide awake.. I will all of the sudden have a "flashback" of a dream that I've already had. I know that I've already had the dream because once the "flashback" starts I remember. It's so intense I can't focus on anything around me. I'm having the dream playback in my head like I'm asleep and dreaming it all over again. I definitely feel like I'm not in this world anymore while this is happening. I'm completely mobile, I can move around and talk but it's not the same. Most of the time I grab m…

Hey everyone, brand new here. So I take MSM daily as it really helps with my joint pain. Really been a godsend for me. Recenty, I stumbled on this study, http://www.ncbi.nlm.nih.gov/pubmed/19336900, which says : "MSM significantly inhibited the release of nitric oxide and prostaglandin E(2) by alleviating the expression of inducible nitric oxide synthase and cyclooxygenase-2 in LPS-stimulated RAW264.7 cells." Now I know nitric oxide is critical for erections , as drugs like viagra promote nitric oxide, as well as nitric oxide being important for other systems as well, so I was very concerned when I read this. My question is: is this saying it is only lowering NO when…

In the case of soft tissue calcification of the throat or larynx, or calcification of cartilage such as thyroid cartilage, how long can one expect it to last? i.e: is it a permanent, long lasting, or just temporary condition? I came across it whilst doing some reading and my curiosity was stirred, but I cannot find an answer to my question anywhere. Thank you in advance for any answers.

Just wondering what instincts are built into the human psyche. For example things like curiosity and will power. Is there a list of things we are born with and from which everything else grows?

First, let me say this is my first time at this forum and didn't know where else to turn. Here's our problem in short. We are renting a home that is making us sick and it seems to be coming from the tap water. When we drank the water we'd get stomach pain, nausea, vomiting, and diarrhea. So we switched to bottled water and all the symptoms went away. We repeated this process a few times of a period of weeks and months. When I say we, I am referring to our entire family. The water company did a so called "extensive water testing" at the request of us and our landlords. Tests were done from the kitchen sink and outside the house at the meter. All tests fell w…

When the body has developed an immunity to a particular strain of virus, either through past infection or vaccination, and the virus enters the body once again it is obviously overcome before it can have any harmful effects. What I was wondering is whether such viruses manage to infect any cells before the immune response takes effect, or if they are totally overcome before this can happen?

Around the internet i have noticed lots of people discussing the subject of marijuana being able to cure cancers. I have read that some scientists tested it on brain cancers and it was successful. What do you guys think?

Very Sorry if i Posted in wrong spot plz move but plz dont delete i need help with my questions! Since I was a kid i was interested in bright lights they never hurt my eyes to look straight at them such as the sun or any other light. Since about 8 y.o. to current i had better then 20/20 vision. My latest was 16/20. i am 23 y.o. now but ever since i was young i seen these weird spheres in light waves. The best way i can describe seeing them and what they look like is this: When I zone in to a bright light at night around the light i see waves emitting off the brightest part of the light, like on a hot summer day when you see the heat waves off the street, in those wave…

Does anyone have a fix for the artifacts (refractiles) that occure during biological reagent staining of blood smears (films)?

What are some adverse health effects that may occur from long term exposure to an environment with increased g-forces? Most of us know that there are deleterious effects to human physiology in microgravity environments, but what about the opposite? Hypothetical: Sam is spending his vacation on Jupiter, where he weighs roughly 2.6 times as much as he does on Earth. What effects to his body can be expected? I know this is a very broad question, so please just throw things out there. Everything from digestive issues to compression of CSF. Thanks.

Hey everybody, I currently run a science blog ( url removed by moderator ) and after writing this article I felt like I should share it with more people! Many of us like to live a healthy lifestyle and by that I mean staying active. Although being humans we can sometimes do the wrong thing and cause some pretty bad damage, whether it's a broken bone or a sprained ankle you should know the answer to the question we commonly ask ourselves.. Do I use heat or ice!? First we must understand 2 forms of pain.. Acute pain and Chronic pain. Acute Pain: Acute pain is usually sudden and can usually be sharp pain in quantity. Examples of Acute Pain: Surgery Br…

Hi, this year i was diagnosed as having had cartilage build up on my left side, specially on the muscle running into the heart, which had moved one morning and resulted in arrhythmia and so forth. Anyway, i have since had sensations that had felt like they were centred in the middle of my brain. Ive had a CT scan, which turned up nothing and my blood pressure is fine. The sensations have felt like sort of slightly pulsating, with tingling regions, moving around in the area of what has felt like my insula cortex, temporal/pariental lobe regions as well as some in the occipital lobe and some in the prefrontal cortex. So basically throughout the middle region(s) of my head, …

I didn't really wanted to ask this cause I've never followed a treatment.But Im 20y.o. and I still have black spots and red spots and white,anyway it's not a necrosis state,it's just annoys me cause some disappear one day, then another round appears.so it sucks. Anyway the question is:Is there a real patented treatment which was proved to be useful and definitive?There are a lot of them I know but is there something that really works?

Hello everyone, I'm glad to join the forums and enjoy some scientific discussions I hope my question is not very specific...I've been reading since a while about nanoindentation of polymers...it is always reported that, longer holding times of the test (creep) leads to obtaining less values of stiffnes similarly...faster unloading rates lead also to less stiffness...but the papers where i read that never mentioned the reason any idea about the reason behind this, considering the creep and the chain movements and all this? many thanks!

Can i just buy the e-book ? I need links & the names for tge books for 2nd year General medicine.
