I have a tendency to believe that stringent laws in the US have an adverse affect on scientific development and progress. More laws makes it difficult and/or illegal for professional scientists to continue their work. It can also completely block amateur tinkerers from improving upon designs or making important chance discoveries. Despite my perception of the state of American law, it appears as though British law is even worse.
The Guardian posted a story a few days ago about a research team that will be leaving the UK for American shores. Apparently they are having a very hard time getting government approval for their research. This team is researching the genetic modification of pigs to grow organs for human transplants.
Welcome to America, fellas. Lets hope our home grown zealots stay an arms length away, I'm pretty sure I'm going to want one of those livers one day.
