Summary: Japanese researchers have done what no other has done before. Scientists cloned living pups( or baby mice) from dead mice, that were frozen for 16 years. One of the researchers extracted nuclei from 2 frozen mouse brains and transfered these brains to a mouse's egg cells " whose nuclei had been removed". And after using stem cells from the said embryos, fertile adult mice were cloned successfully. Because this particular experiment was so successful, it proved the popular belief that ice crystals ( from frozen tissue) damage a cell's nuclei was wrong ( but deteriorated tissue thousands of years old might be another story). Japanese researchers hope to use future samples to clone extinct and/or endangered animals. I think this article was very different because of the fact that frozen cells were used to clone animals. This //might// open the door to bringing back extinct animals like, I don't know, DINOSAURS. I'm not saying this is a good thing, because I'm against that notion completely, but in the future we as a society will have to decide as people whether or not we want extinct animals to walk this earth again. That's basically what I thought about the whole article, because it was kind of short, but that main idea was a very interesting one to think about.
