New Dye was Adopted Quickly in the 18th Century

Despite this being a "scientific"age, not everything is known about the technology of the past.  New research shows that adoption of new things was quite rapid in the 19th century  For example, a dye was being used industrially only four years after its invention.
Methyl violet dye used to make a 19th century dress
Examination of purple threads from dresses by molecular spectroscopy shows that shows that it was widely used by consumers. Before synthetic dyes were developed only royalty could afford purple dresses as existing dyes were made from molluscs.

After analysis using thin layer chromatography, energy dispersive x-ray and enhanced Raman spectroscopy a dye was identified in three dresses as being methyl violet. It was invented in 1861 and in shops by 1865, Even today getting a new product to market is usually only done with computer related merchandise.

Consuming More Tea and Coffee Prevents Diabetes - Doubtful

Claims about consuming certain things to improve health are way off beam. Every now and then supposed new research shows that if you eat this or don't eat that your health will improve.

Well, apparently drinking up to three cups of coffee or tea each day reduces the risk of getting diabetes. Look around. Do you see people who drink these beverages regularly with diabetes? You sure do. There are thousands of them. The University of Sydney says “If such beneficial effects were observed in interventional trials to be real, the implications for the millions of individuals who have diabetes mellitus, or who are at future risk of developing it, would be substantial.” Their trials must be wrong. Surely millions of regular drinkers who have diabetes are thinking, "Why me? Why have I got the disease&qu

Anthropology Has New Theory on Australian Aboriginals

New theory on Australian Aboriginals - Anthropology. Australian Aboriginals split from Eurasians and moved south into the dry continent. Twenty thousand years later the world warmed up and Australia was cut off from its northern neighbors. This is the latest theory.  But when Europeans initially came to Queensland there were two types of native people. Each was a distinct genetic pool. One was like Papua New Guineans.

There is also the question of Tasmanian Aboriginals who were wiped out by arriving Europeans. There is no evidence of them now. They could not light fires. The flames had to be stolen f
