According to archaeologist David Anderson of the University of Tennessee, however, minerals in seawater can sometimes alter the carbon 14 content of bones, resulting in inaccurate radiocarbon dating results.The remains were found some 50 feet (15 meters) below sea level in the caves off Tulum.
But soon these discarded discs could take on a different role: ...
Radiocarbon dating measures the age of organic materials based on their content of the radioactive isotope carbon 14.
Method A scientific date is either absolute (specific to one point in time) or relative (younger or older than something else).
Dendrochronology, or tree-ring dating, provides absolute dates in two different ways: directly, and by calibrating radiocarbon results.
Buckyball sandwiches combine fullerenes and graphene. Scientists have created crystals that capture carbon dioxide much more efficiently than previously known materials, even in the ...
The chemical properties of atoms depend on the number of protons in their nuclei, placing them into the periodic table.
A team of researchers has derived the first theoretical equation to demonstrate that global ...
Now that most consumers download and stream their movies and music, more and more CDs and DVDs will end up in landfills or be recycled.
As a result scientists can measure the ratio of normal carbon (C12) to radioactive C14 and use the ratio to estimate how long a plant animal or any products from them such as timber or cloth, has been dead.
