How is the Night Luminous Pearl (frequently given as gifts to Emperors in Ancient China) formed in nature and how are they harvested ? What is the difference between this Luminous Pearl and normal Pearl from Oysters e.g its mineral contents ? Is it found only in China, as no other countries seem to refer to it in history. Currently, where can one view / purchase a real Night Luminous Pearl ?

The Night Luminous Pearl is nothing but a Chlorophane, a variety of flourite with some REE (Rare Earth Elements). These elements act as activators and deactivators. Due to these rare earth elements the flourite stores heat energy from natural sun light and release same in darkness. Some Fluorites would need UV short wave(SW) or long wave(LW) light to glow. This fact was published in many chinese journals as early as 16th century and was known to west only in 19th century, one such article was published in Harper's Monthly magazine in 1890

The similar Night Luminous pearl or chlorophane is found in siberian mines of Russia and few other places. The cobra also makes use of small luminous pearls to hunt insects and rodents and carry this kind of pearl, it is also called cobra pearl/serpant stone. But it is not formed inside the body of snake and it is picked from dry river beds. A small pea size cobra pearl is valued at few million USD, which is actually fluorite with night glow.

Hello,can some1 please help me to undstand what is the difference between NUCLEOPHILICITY and BASICITY.After going through books,i have learnt that they are somehow directly proportional in terms of strenght.But I'm bit confused as I find sometimes stronger nucleophiles are weaker bases.also i found that type of solvent affects nucleophilic nature.My text books dont explain clearly why.Can Some1 please help?

Thanks a lot,that made some things much clearer to me.But smthng still confuses me.I now undstand about this nucleophilic strenght being reduced in protic solvents due to H-bonding(i know now after i looked up the terms here after your reference about the action of such solvents),but why is the basic strenght not reduced too.i mean isn't the strenghth of a base also measured by its ability to co-ordinate with a proton.if its lone pair is hindered(thereby making it a weaker nucleophile evidently),then why doesn't its(or does it)proton abstraction ability decrease hence making it a weaker base according to the definition of a lewis base if i'm not wrong.I'll be really grateful if you can clear my doubts.Thanks mr...umm Someguy —Preceding unsigned comment added by Abhiroopron ( talk • contribs) 11:40, 1 June 2008 (UTC)

Hi - our articles are a bit vague on the actual properties of the protein solution that passes through spinnerets to produce silk. Is it called 'silk dope' or is there a more technical general term? What does it look like en masse? What is its colour, viscosity etc?
Thanks Adambrowne666 ( talk) 17:58, 31 May 2008 (UTC)
Thanks for that, Julia - and thanks, all, for your efforts - I'm starting to realise it's a ridiculous question, like asking what a gallon of pure DNA looks like. Adambrowne666 ( talk) 00:52, 2 June 2008 (UTC)
btw, I have a vague memory of a newspaper article about a science project where they derived several grammes of pure DNA from onions - wasn't an extraordinary stuff, as I recall, pale grey goop - if it was up to me, it'd be a prismatic soup visibly fizzing and zinging with genetic potentialities - probably best if I don't know what silk stock looks like - more fun to make it up Adambrowne666 ( talk) 10:47, 3 June 2008 (UTC)
I hope I'm not too late. I think it is feasible (but impractical) to isolate the unspun spider silk proteins. First isolate it from a producer that can provide it en masse like a Spider goat. Second, find a way to separate the milk from the silk using methods such as High performance liquid chromatography. I'm not sure how much protein per liter of milk though. Maybe around 1 gram.-- Lenticel ( talk) 09:06, 4 June 2008 (UTC)
When I was three, I had an athsma attack with another disease at the same time. I do not remember the name of the disease, but I could not breath in or out. The last I remember of that day was falling asleep after a mask was put on me, leaving me to believe I had surgery. Ever since then, I have only had acute bronchitis, not general asthma. Does anyone in the medical field know what treatment could possibly lead to this(As well as what the disease could be)? I have a highly curious mind, so semi-complex awnsers are okay, just try not to get all E=MC2 over me. 67.171.165.4 ( talk) 20:34, 31 May 2008 (UTC)
My daughter is going through puberty and is starting to develop acne. I'm trying to find research papers and information regarding the effect of physical exercise on acne. Thank you.-- Goon Noot ( talk) 20:36, 31 May 2008 (UTC)
I did not ask for medical advice. I specifically asked for research papers and information. Not advice.-- Goon Noot ( talk) 22:10, 31 May 2008 (UTC)
I know this isn't probably the best place to ask for exercise advice, but I had some questions about the notion of between-lifting rest. I know you're not supposed to lift weights every day, because you need to give your muscles time to rest and regrow. But I've also heard that there are some muscles that it's OK to work every day (like, it's OK to run daily, I think), and I've also heard that abs work like this. I've also heard something, which doesn't make much sense to me, about how body-weight exercises (push ups, pull ups, etc) can be done daily, for some reason possibly having to do with lightness of weight. Do any of you know, from personal or scientific knowledge, how much of this is accurate, or what the real story is?
And, regardless of what particular muscles and exercise types call for what types of rest, what are the deleterious effects of not getting enough rest time? Will my muscles grow less if I do pushups daily than if I did them every other day? Will the muscle be more dense? Bigger? More wirey? I don't know.
And which is it that causes denser muscles, heavy weightlifting or many reps of lighter (bodyweight etc) weights? Or is the different-muscle-type-by-different-exercise stuff I've heard about pretty much made up?
Thanks,
