So since cloning humans is a ways off still, the next best thing would be stem cells. Stem cell technology can be great at fixing the human body. Slow but real progress is being made. Just in 2008 a team of scientist grew a beating heart of a mouse almost from scratch by dissolving the cells within that heart, leaving a mixture of heart stem cells and watched as the stem cells grew individual heart cells in a petri dish. Making this the first beating heart to grow in a lab.
Teams are also looking into body parts as well. Take the eye. It can be damaged causing blindness. Stem cells are being investigated for treatment for blindness and vision impairment. This new treatment is now in clinical trials for testing.
Not only scientist but now the U.S. Army is also interested in tissue engineering. They have made it a priority to find a way to grow back limbs. A team of scientist has already successfully re-grown fingertips with a dust known as "pixie-dust." So perhaps the next step would be to re-grow limbs. All this may sound like something from the movies but in the next decade it may be another sci-fi gadget "item" that becomes sci-fact.
Wow! sounds cool!
I'll see you next time
