This came from the Jan 12th edition of Physics News Update (which, if you haven't subscribed to it already, you should smack yourself on your head). It appears that that Einstein fella also had his hand in something that could lead to new blood separation technique. This all came when Einstein explained the phenomenon of how tea leaves settle on the bottom of a cup. For heaven's sake!
This Einstein guy has his nose in almost everything. He's beginning to annoy me!
