Are the Rules That Determine Who Can Donate Blood Discriminatory? Canadian AIDS researchers Dr. Mark Wainberg and Dr. Norbert Gilmore say that while the ban on blood donation from men who have sex with other men may have been ethically and scientifically justified in the 1980's, it no longer makes sense.

Blood, sweat and tears

Is blood plasma salinity the same as seawater? No, but that proves evolution. "The answer is most definitely NOT that oceans were 1/3 as salty back then. It most definitely IS that the earliest vertebrates did evolve in salt water and then moved into fresh water....They have devised an extremely clever trick in kidney structure to allow salt transport pumps which really take salt back INTO the body from the urine but still manage to use them to produce urine much more concentrated that their body fluids and so excrete salt FROM the body."

Blood Substitute.

Loyola University has received approval to investigate PolyHeme®'s use as a blood substitute for critically injured and bleeding trauma patients at accident scenes. Blood has a very short shelf life, requires refrigeration, and matching types takes too much time too carry blood in ambulances. The blood substitute has a long shelf life and is compatible with all blood types. It's designed to furnish oxygen which will "prevent organ damage in the brain, heart, lungs, liver and kidneys," until a transfusion can be done at the hospital. - pretty damn cool. I hope it works.
