Can stem cell research save endangered species?
Scientists have created stem cells for two endangered African species--the northern white rhino and the drill monkey. They "reprogrammed" skin cells to make them revert to stem cells, an early stage of cell development in which a cell can develop into different types of specialized cells.
It's hoped that one day these stem cells could be made into sperm and eggs, leading to test tube babies that could bolster dwindling populations of some species. This has already been achieved with laboratory mice.
The white rhino used to be a favorite of safari goers and, unfortunately, big game hunters. There are probably none left in the wild, and only seven in captivity. These rhinos are the poster children of how tourism can hurt the environment.
This stem cell breakthrough is good news. With Obama scrapping tighter smog regulations and China discovering just how much they've screwed up their environment, we can't rely on our so-called leaders to get us out of this mess. While environmentalists say we all need to change our attitudes in order to save the planet, that's unlikely to happen. In fact, science is the only part of society that regularly advances. Common sense, foresight, and wisdom sure don't.
Here's hoping the scientists can give us a world where our children don't have to go to a zoo to see wildlife.
