Stem cells

"Previous methods to create embryonic-like stem cells have used a virus to help transform adult cells into pluripotent stem cells -- cells that can develop into most other cell types. But those methods carried the risk of damaging the cell's DNA. With damaged DNA, the cells often became cancerous or led to abnormalities...

"Dr Kaji had found a non-viral method to deliver four genes in a single fragment into a cell genome. However, he couldn't figure out how to remove all trace of reprogramming from the genome. Dr Nagy's group, meanwhile, had developed a system that allowed the removal of inserted genes without leaving a "footprint," but couldn't figure out how to deliver four genes into the same part of the genome. The teams' breakthrough came when they combined their methods."


"The presentation or 'gift' of the Holy Ghost simply confers upon a man the right to receive at any time, when he is worthy of it and desires it, the power and light of truth of the Holy Ghost, although he may often be left to his own spirit and judgment." --Joseph F. Smith (manual, p. 69)

"Inasmuch as ye have done it unto one of the least of these my brethren, ye have done it unto me."
