Japanese researchers have grown sperm in the laboratory for the first time, reports Nature. If the breakthrough with mice transfers to humans, it could open up IVF treatments for infertile men, notes the Guardian. Scientists created the sperm from the testicular tissue of mice and successfully produced a dozen baby mice with it.
The tissue worked even after being frozen, suggesting that men—or even boys too young to produce sperm—could freeze tissue for later use if they were undergoing chemotherapy or other treatments that can cause infertility. “The report is quite exciting because it represents the fulfillment of a goal held by many reproductive biologists over many years,” says an expert in the field at the Jackson Laboratory in Bar Harbor, Maine.
“There was a time when the wealthy elite actually paid substantial taxes. The purpose of taxing the extraordinarily rich is to prevent an aristocracy from developing and to maintain a true democracy, a feat Aristotle recognized as impossible in the face of great income inequalities. Now, after over 35 years of cut, cut, cut for the rich, we have the most powerful aristocracy in history, and they are waging war against the rest of us. If you follow the results of studies that show the disparity of wealth in the US, you will see the flow of money from the bottom 90 percent to the top 1 percent over the 60 years between 1950 and 2010. The statistical evidence of the existence of class war is the direct result of the wealthy elite’s ownership of Congress, the executive branch and the courts.”—Class Warfare, the Final Chapter
