To baaa or not to baaa?
Professor Esmail Zanjani from the University of Nevada unveiled a genetically engineered sheep- well, technically a sheep, we think -that has 15 percent human cells and 85 percent sheep cells this past week. Zanjani injects adult human cells into sheep fetuses to create these chimeras with the eventual goal of "growing" human organs inside the sheep for transplant into humans.
In an example given by Zanjani, he hopes one day to take bone marrow cells from a sick patient, implant the cells into a sheep fetus and literally grow bone marrow for the patient inside the animal. Just one sample of cells from the patient "would provide enough stem cells to do about ten fetuses. So you don't just have one organ for transplant purposes, you have many available in case the first one fails," says Zanjani.

Bleiman Brothers Profile
In the wild, Andrew feeds on fish, sponges, small crustaceans, nematode worms and protozoans.
Benny's diet is very specialized, consisting mainly of the interior of Ramy nuts, nectar from the Traveller's Palm tree, some fungi and insect grubs. He is also known to raid coconut plantations, and has been seen eating lychees and mangoes, which are also plantation crops.

Holy cow (sheep), I never saw this before. I'll have to check out all your early posts.

I think this is a brilliant idea, and we should be grateful to the scientists for providing us with treatments for serious diseases. But people claim it is unethical; you'll notice this is usually healthy people without the diseases that can be cured by this research.
