I think Firstlady made a really awesome attempt.

"Cryo" does mean cold. Cryogencis is a field of biology which deals with frozen organisms. Cryonics is the movement which tries to freeze people while they're only 'mostly dead' so that medical science can revive them in the future.

Cryoglobulins fall out of solution at below body temperature, which I guess could thicken the blood if it got cold. I'm not too sure regarding the disease scenarios.
 
So it's the exact opposite of what I said... :(


So are we looking for a disease that causes body temp to drop enough for the protein to fall out? Or for the disease/illness that results from the protein falling out?
 
ok by now the correct answer has been hidden in 5 or so posts :mischief: difficult to assess who is the closest but I think Firstlady should go next for heroic effort :devil:

Cryoglobulins are antibodies (Immunoglobulins) that fall out of solution at temperatures below 37°C usually something around 33°C or thereabouts but this is just a rough estimate. This can lead to blockage of blood circulations in very small vessels at the body surface (which usually are below 37°C to begin with and in cold weather can go far below that) leading to pain and eventually death of that tissue (like finger tips, parts of the nose etc.).
It occurs in certain malignancies of the lymphocyte system such as some myelomas, in autoimmune diseases like Lupus erythematosus and most often in hepatitis C patients...

Edit: though El Machinae was closer in fact - so you and First Lady should just make it out between the two of you (I guess first to post a question wins :p)

Take it away, El_Machinae! :)
 
Another biology one.

Heat Shock Proteins are highly conserved protein. They are so-named because when you subject yeast to too much heat, these proteins increase and help protect the yeast against next 'heat shock'.

These proteins are still around in people, or at least their homologs are.
Would anyone like to say how they can be induced in people?

This seems fairly similar to the Mad Cow question from awhile ago.

Exercise?
 
Heat Shock it is! It has maintained that trigger, despite the vast evolutionary distance between us and yeast.

Now if only Sonic Hedgehog protein had been named properly ....

Brighteye!

just two mirrors; the light enters from the right, reflects on the first mirror, gets focused, goes on to the second, smaller mirror and exits the telescope
 
Is that the thing which makes two very flat surfaces which are very close to eachother (a few microns at the most) feel an attraction?

That works because of the continuous particle and anti-particle pair that are constantly created in the quantum vacuum. As particles can only have a 'whole' amount of energy there wavelenght must fit a whole number of times into the gap in which they are created. When the plates are very close together, there is a limited number of wavelengths for which this works, and thus fewer particle/anti-particle pairs are created inbetween the two plates than outside the two plates. This means that there is a stronger force from the collision of the particles onto the plates outside than inside and thus a net pressure pushing the two plates together.
