Nuclear Fusion reactors may reach the prototype commercial stage
, The causes and possible treatment of Alzheimers Disease and Partial cloning of human organs for transplant therapy
Explanation:
Fusion may be an energy technology that seems to be perpetually coming over the horizon, but projects around the world such as SPARC are getting increasingly close to reactors that, although smaller in capacity, can produce net positive power in just a few years. To help accelerate discovery of permanent cure for Alzheimers, an alliance of pharmaceutical companies, nonprofit foundations and government advisers, has developed a partnership to share data from Alzheimer's clinical trials. This would definitely pave way for the permanent cure for Alzheimer. The most common method of therapeutic and reproductive cloning is somatic cell nuclear transfer (SCNT). SCNT involves separating the nucleus from a donor egg, and replacing it with the DNA from the organism meant to be cloned. Scientists could potentially clone organs with SCNT by cloning embryos, extracting the stem cells from the blastocyst, and stimulating the stem cells to differentiate into the desired organ. these three scientific and technological advancements are possible.
