causes of high ferritin
Hello,
In case of a very high ferritin value (900+) for a long period of time (year+),not due to iron overload (ruled out by transferrin/iron), is there a list of possible diseases? I understand high ferritin+ESR+CRP is a "nonspecific inflammation", but is there a protocol for treating this? Mathityahu (talk) 00:34, 3 November 2008 (UTC)
Biological Condition of Not Being Able to Sing
I once read, while studying for my music degree, that there is a rare condition that precludes an individual from the ability to sing. I cannot recall the name of that condition and would like to know what it is so that I can research it and learn more. I believe, for the most part, that if you can talk you can sing and would like to research this "rare condition" further. My clouded memory gives me the word "amesia" for the, but I cannot find that word in Wikipedia or any other dictionary that I have checked, so assume it is probably not the correct word. Does anyone know more? I have hit a dead end in my research on the web.Kschwacog (talk) 01:18, 3 November 2008 (UTC)

cognitive power of a feline
a domesticated cat sees a kitchen counter. It knows to get on that counter it must jump. Once the cat is on the counter can it determine that BECAUSE it jumped it is on the counter? Thanks, 32.149.68.21 (talk) 03:16, 3 November 2008 (UTC)
Seeing my black cat curled up on a black blanket, I wonder whether anyone has experimented to see whether cats are aware of their own color and the availability of camouflage, e.g. by letting black cats and white cats choose favorite spots in a room whose walls and floor are half white and half black. —Tamfang (talk) 17:15, 3 November 2008 (UTC)

How many video game references can you find in the Arecibo message? In the middle, there's a blue and white guitar from Guitar Hero. Below that is the human in Berzerk. Finally, at the bottom is one of the space invaders. 67.184.14.87 (talk) 04:15, 3 November 2008 (UTC)
charging objects..
I have been given an assignment. 8 point electrical charges are placed at the corners of a cube and another point electrical charge is placed at the centre of the sphere. I have to experimentally show that the 9th electric charge will not be in stable equilibrium. I have a theoretical explanation for that using Gauss's law. To do it experimentally, I thought I will use charged (conducting)spheres as point charges. I can charge a sphere using induction method. Is there any other way to charge a sphere?Please help. Also, suggest some ways to place the spheres at the corners of a cube. —Preceding unsigned comment added by 210.212.187.69 (talk) 04:28, 3 November 2008 (UTC)
DNA
Can DNA be seen in a microscope? ~DahiJynnuByzzuf~
Let me rephrase it, are there microscopes that can magnify until the DNA looks like the way it's pictured in illustrations? DahiJynnuByzzuf (talk •
Okay, let me try this. Does DNA look like a ladder under the microscope? DahiJynnuByzzuf (talk —Preceding unsigned comment added by 75.110.204.225 (talk) 09:38, 3 November 2008 (UTC)

Is it only the bird that they're in a relationship with that they cuddle up to or do lovebirds just like to get close to each other in general? --90.240.85.78 (talk) 08:18, 3 November 2008 (UTC)

Why do plants use chlorophyll?
Why do plants use chlorophyll which is a green pigment? Wouldn't it be more useful to use a red pigment so that red light, which is of a high wavelength and thus low energy, is the only light not used? Taking it further, couldn't they use a black pigment? Are there any reasons or theories for why chlorophyll is used? --RMFan1 (talk) 12:03, 3 November 2008 (UTC)

Preventing inbreeding among critically endangered animals
I read,via a featured yahoo article (here ), about the rare sighting and photographing of a Far Eastern Leopard (i.e., the Amur Leopard) wherein concern was expressed on the matter of probable genetic defects arising due to inbreeding among the critically low population of Amur leopards. What methods could/do the scientists use to prevent these defects when attempting to revive the population of a critically endangered species?--Leif edling (talk) 17:19, 3 November 2008 (UTC)

THC effect on blood donation?
I smoke Marijuana daily. After voting tomorrow, I intend to give blood. Will the THC in my blood cause my donation to be discarded? --Unshelled Peanuts (talk) 18:30, 3 November 2008 (UTC)
Generally, though, if the blood bank doesn't ask a question about illicit drug use in general (not specifically IV drugs), they didn't care about it in the first place and won't throw out the blood. THC and marijuana consumption are not considered to be "of interest" for blood safety, the only drugs that are always a concern are IV ones (since that's an infection route for HIV and hepatitis). Some blood banks have stricter policies, but they're not recommended (at least by any guidelines I've seen). If you're too stoned to give a straight answer or remember what else you might have done, that might be a problem, but the same is true for alcohol. SDY (talk) 22:37, 4 November 2008 (UTC)
Why Earth's rotation slows down?
I was just reading about how leap seconds are added to the UTC time because Earth's rotation is slowing down. Has this been happening since the Big Bang or does it increase and decrease in cycles? If not a cycle, wouldn't Earth eventually stop rotating? Elfalem (talk) 20:16, 3 November 2008 (UTC)
Are there any legitimate scientific alternatives to evolution?
Are there any legitimate alternative scientific explanations to evolution? For example, for the causes of global warming, solar variation is a legitimate alternative scientific hypothesis. Are there anything similar alternatives to evolution? 216.239.234.196 (talk) 20:48, 3 November 2008 (UTC)
Mesoscaphe
The noted oceanographer and submersible designer Jacques Piccard recently passed away. In the Wikipedia article on him he is credited with the design of the bathyscaphe Trieste. He is also credited with the design of the mesoscaphe Ben Franklin (PX-15) and commanded the mission in 1969. There is no reference or link to "mesoscaphe" in Wikipedia. What is a "mesoscaphe" and how is it difference from a bathyscaphe? Garybirk (talk) 20:58, 3 November 2008 (UTC)
