What is the news story about?
As far as cloning goes, Japanese scientists have made an even further advancement by now finding a way to clone bodies of mice that have been frozen for as long as 16 years. From this advancement, there is a possibility of cloning extinct species of animals. It has come into consideration that even long extinct animal called the mammoth, can be resurrected.
What is its significance?
Scientists have found a way to unfreeze frozen cells that the frozen mice contained. By using a chemical called cryoprotectants, it can prevent the frozen cells from bursting and damaging the DNA inside. Although, a downside is that cryoprotectants must be used before the cells are frozen.
"However, it has been suggested that the 'resurrection' of frozen extinct species (such as the wooly mammoth) is impracticable, as no live cells are unavailable, and the genomic material that remains is inevitably degraded," they said.
Is there any bias?
I don't believe that there are any bias since it is an informative article that looks at cloning in perspective. The mice cloning was successful, but now scientists are pondering about cloning the extinct mammoth species. Instead of bias views, rather there are more concerns.
