Science writer and psychiatrist Ben Goldacre takes a historical look at homeopathy and its critics while reviewing the often misrepresented results of over 200 scientific trials. His talk gives an, at times, humorous explanation of what homeopathy is and why its principles are implausible and even “childish”.
I was intrigued by the statement that we don't really know how anesthetics work. I thought they were generally understood. Any medical folks care to comment?

Wish the sound had been a little better but good stuff. Zoroaster It was probably a good example to a medical person but I, like you, thought we knew what made them work. Overall, he gave a good talk. I Liked his part about "Bad research is unethical".

Well, I'm not a Medical Professional (*but I did stay at a Holiday Inn Express...), but looking at wikipedia it does seem that he is accurate.
It has always been believed that general anaesthetics exert their effects (analgesia, amnesia, immobility) by modulating the activity of membrane proteins in the neuronal membrane. However, the exact location and mechanism of this action are still largely unknown although much research has been done in this area. There are a number of outdated and modern theories that explain anaesthetic action.
This is a very good article written, but also very attractive to me some information. I swear I was the first time I saw such beautiful jewelry, high-end brand, the credibility of the guarantee, beautiful shape, it will capture your heart. Thanks for sharing. .
