1. Scientists Clone Human Embryos To Make Stem Cells : Shots
The achievement is a long-sought step toward harnessing the potential power of such cells to treat diseases. But the discovery raises ethical concerns because it brings researchers closer to cloning humans, and involves creating and then destroying human embryos for research purposes.
