Morning Update

You know that TV crocodile hunting team Steve and Terri Irwin? Well those
two can expect some competition in days to come. Scientists in northern
Australia have been collecting blood from crocodiles in hopes of saving

Studies in the late 90s showed that several antibodies in croc blood killed
penicillin-resistant bacteria. More recently it has been discovered that
crocodiles' immune systems can kill the HIV virus. American scientist Mark
Merchant says the reptiles "tear limbs off each other, [but] they heal up
very rapidly and normally, almost always without infection." Aussie
scientist Adam Britton adds: "The crocodile has an immune system which
attaches to bacteria and tears it apart and it explodes. It's like putting
a gun to the head of the bacteria and pulling the trigger."

These two scientists draw blood from wild and captive crocs, saltwater and
freshwater species. After capturing the donor, they strap its jaws and go
for a vein. The vein, Britton says, is "called a sinus, right behind the
head, and it's very easy just to put a needle in the back of the neck and
hit this sinus and then you can take a large volume of blood very simply."

It'll be years, of course, before croc blood is ready for human use. Their
antibodies are so powerful they may have to be diluted. But this is pretty
remarkable on two fronts. Once again, proof that embryonic stem cells
aren't the only "miracle" cure for all that ails us. And more importantly,
understanding how crocodiles heal points to a pretty intelligent design in
nature. Now when are the animal rights people going to start complaining to
stop all of this? ~ Rush Limbaugh
