Rowe hopes to use it, for instance, to analyze objects such as a small ivory figurine called the "Venus of Brassempouy," thought to be about 25,000 years old and one of the earliest known depictions of a human face.

The figurine is small enough to fit into the chamber used for analysis.

I would be more convinced with further scientific evidence (how surprising – a scientist wants more science to back up their conclusion).

It would be exciting to find that Leonardo da Vinci really did paint another . It would surely increase the value of the painting, but not the beauty.

Then they treat the sample with a strong acid and a strong base and finally burn the sample in a small glass chamber to produce carbon dioxide gas to analyze its C-14 content.

Rowe's new method, called "non-destructive carbon dating," eliminates sampling, the destructive acid-base washes, and burning.

The chamber could be sized to accommodate large objects, such as works of art and even the Shroud of Turin, which some believe to be the burial cloth of Jesus Christ, Rowe said.

He acknowledged, however, that it would take a significant amount of data to convince museum directors, art conservators, and others that the new method causes no damage to such priceless objects The scientists are currently refining the technique.

One popular theory about the Paleolithic cave paintings proposes that sites were chosen based on the acoustics in the caves.

There are a number of scientific techniques that can give us clues about the author of an artwork: , the Mona Lisa Foundation has not made it public.

Instead, the Foundation developed their own test of authenticity.

Rowe and his colleagues used the technique to analyze the ages of about 20 different organic substances, including wood, charcoal, leather, rabbit hair, a bone with mummified flesh attached, and a 1,350-year-old Egyptian weaving.

The results match those of conventional carbon dating techniques, they say."This technique stands to revolutionize radiocarbon dating," said Marvin Rowe, Ph. "It expands the possibility for analyzing extensive museum collections that have previously been off limits because of their rarity or intrinsic value and the destructive nature of the current method of radiocarbon dating.In theory, it could even be used to date the Shroud of Turin." Rowe explained that the new method is a form of radiocarbon dating, the archaeologist's standard tool to estimate the age of an object by measuring its content of naturally-occurring radioactive carbon.Scientists have developed a new method to determine the age of ancient mummies, old artwork, and other relics without causing damage to these treasures of global cultural heritage.
