At a widely publicized news conference in August ofDr. Jeffrey Bada of Scripps Institute of Oceanography announced the "discovery" of a new dating method based on the rate of racemization of amino acids in fossil material. He was quoted as saying that he had discovered the basis of the method inand that it was so obvious and simple he was amazed it hadn't been discovered earlier. As a matter of fact, the basis of this method had been discovered earlier and had been reported in a series of papers published by Hare, Mitterer and Abelson in, and Amino acids are the "building blocks," or sub-units, amino acid dating method proteins. About 20 different kinds of amino acids are found in proteins.
Amino acid dating has an important attribute in common with Carbon 14 dating. While most other dating mechanisms date the rock surrounding fossils, both Amino Acid and Carbon 14 dating methods, date the actual fossil itself. This ability to date the actual specimen could make the Amino Acid dating procedure very valuable. However, Amino Acid dating has problems. Even in the scientific community, Amino Acid Dating is considered controversial. The amino acid dating method is affected by all sorts of conditions that make Amino Acids change their stereochemistry at different rates. Later on, in this web page, we will look at the many parameters that affect this rate of amino acid change in fossils. The major weakness of the Amino Acid dating process is that it is not able to produce dates purely from the data alone.

More about amino acid dating method:
Amino acids are the building blocks of proteins. At the death of the creature that they were in, amino acids begin decomposing at varying rates. A major difficulty in applying this dating method is that, of the twenty amino acids, some decompose much more rapidly than others. Scientists can only try to estimate the age when an animal died by the amount of decomposition it has experienced since death. Gradually more stable compounds remain while others decompose in varying ways. Accompanying this is the problem that various organisms have different ratios of amino acids. Each type of plant and animal has its amino acid dating method special amino acid ratios.
During fermentation, yeast multiplies five to eightfold and generates heat. The researchers cant say exactly why curcumin might have these effects.

In the study 96 amino acid dating method aged between 40 and 90 were given either a daily placebo or 1, mg of curcumin for 12 months. In their study, the researchers attached curcumin to cerium oxide nanoparticles and tested the nanocurcumin formulation in cell lines of a highrisk form of neuroblastoma.
Amino acid dating is a dating technique      used to estimate the age of a specimen in paleobiology , molecular paleontology , archaeology , forensic science , taphonomy , sedimentary geology and other fields. This technique relates changes in amino acid molecules to the time elapsed since they were formed. All biological tissues contain amino acids. This means that the amino acid can have two different configurations, "D" or "L" which are mirror images of each other. With a few important exceptions, living organisms keep all their amino acids in the "L" configuration. When an organism dies, control over the configuration of the amino acids ceases, and the ratio of D to L moves from a value near 0 towards an equilibrium value near 1, a process called racemization. Thus, measuring the ratio of D to L in a sample enables one to estimate how long ago the specimen died.
