Hypnosis- common myths uncovered
Before I tell you about hypnosis, let's get a few myths out of the way. Hypnosis is not a cure-all, or a magical power. It isn't going to make you a millionaire or let you 'cast spells' to make women fall madly in love with you. It's not a science, but it's not a complete load of rubbish either. So what is hypnosis Basically, it is the power of suggestion.

Medical Device Process Validation Acceptance Criteria
When you choose your process validation acceptance criteria you should have a statistical basis for rationale. Because we (medical device industry) are a science based community, statistical relevance is almost a given for supporting your validation with well derived and accurate conclusions. One of the elements of a good validation is to include a minimum confidence level for your data of which you will draw your conclusions from.

Newly Revealed 3600-Year Old Wisdom Text Describes Extinction of the Dinosaurs
In recent years, scientists have begun to challenge the popular K-T extinction event theory advanced by Nobel laureate physicist, Luis Alvarez. In 1990, he found evidence of a large impact resulting in an Extinction Level Event (E.L.E) in what is now Chicxulub, Mexico. His theory that this E.L.E. wiped out the dinosaurs some 65 million years ago was soon adopted.
Cavemen were smarter than we thought
Science textbooks usually present cavemen as very primitive people who were barely able to utter a few monosyllables. However, as additional data about stone age men are unearthed, the picture becomes considerably more complex. It seems that the more we know about them, the more modern traits they seem to acquire.
A recent study published in the Journal of Archaeological Science suggests that cave dwellers wore shoes. Erik Trinkaus and Hong Shang of the Washington University in St. Louis, Missouri studied the toe bones of a skeleton found in a cave near Beijing. They compared these with the toe bones of modern Americans, Inuits and Native Americans from the time before the advent of the European conquerors. Shoes alter the wearer's toes. People who regularly walk barefoot tend to have strong and large toes while those wearing shoes do not. Trinkaus and Shang concluded that the Chinese cave dwellers regularly wore shoes.
The obvious conclusion is that cavemen were less primitive than we had thought. This same trend can also be seen in how Neanderthal man is presented. First specimen was discovered in 1856 in the Neander Valley in Germany and named after the place where it was found (Tal is valley in German). They were initially described as virtually subhuman missing links. With the passing of time, however, scientist have had to discard their previous notions about them. It is now known that the Neanderthals made musical instruments and efficient weapons, buried their dead and even used toothpicks.
It thus seems that the neat progress from primitive to modern man does not exist. The cave dwellers were not primitive people.
