During the Manhattan Project, one of the most dangerous experiments was called, 'tickling the dragon's tail.' To determine the mass of uranium necessary for a chain reaction, scientists at Los Alamos constructed a near-critical pile of uranium and then dropped a slug of uranium through it. Although gravity reliably pulled the slug down and way from the mass, for a split-second, the amount of uranium was sufficient for a chain-reaction. Although extremely hazardous, it was the safest experiment Oppenheimer and his team could devise.
The Mouse With a Human Liver tells about Salk Institute's generation of a mouse with a near-human liver. (About a 95% match.) The idea is to create a viable test subject that experiences the same liver infections and diseases as a human. Instead of limiting researchers to a petri dish of a few cells, this permits test and observation of a complete organ.
The Salk Institute explains the researchers created the human liver from a mouse that has genetic defect. By introducing human cells into the liver, the mouse liver becomes populated with human cells. Tests show the mouse experiences human liver infections and diseases.
Mmm. New Bill Would Ban Human-Animal Hybrids tells this is a complex issue. All of us believe medical research for the purpose of curing or preventing human diseases is unquestionably good. But suppose Weeki Wachi Springs, a longtime Florida tourist attraction wants to create true mermaids instead of being content with beauties that breath through transparent air hoses? Should that be permitted?
Okay, what is the demarcation between acceptable blending of human genes within an animal?
