An international team of researchers has conducted a new test of Neanderthal remains found at Vindija Cave in Croatia and found them to be older than previous studies indicated. In their paper published in the
Proceedings of the National Academy of Sciences, the team describes their dating technique and the possible implications of their findings.
The Neanderthal remains were originally found in the cave approximately 40 years ago and have been tested for age several times. They have also been the subject of much speculation, as
it was thought that the remains represented the last of the Neanderthals in that part of Europe and that they existed for a short period of time in close proximity to modern humans. Initial testing suggested the remains were approximately 28,000 to 29,000 years old. More recent tests have put them at 32,000 to 34,000 years old. Both time frames coincide with the arrival of modern humans into the area, keeping alive the theory that the two groups mixed, both physically and socially. But now, using what is being described as a more accurate technique, the group with this new effort has found that the remains are older than thought.
The new technique, called ZooMS involves radiocarbon dating hydroxyproline-an amino acid taken from collagen samples found in bone remains. The team also purified the collagen to remove contaminants.
The researchers report that the new technique indicates that the remains-all four samples-were approximately 40,000 years old. This new finding puts the Neanderthal in the cave well before the arrival of modern humans, thus, there could not have been mixing of the two.

UPDATE from Ars Technica:
Scholars have started to debunk these claims about the Voynich manuscript, noting that the translation "makes no sense" and that a lot of the so-called original findings were done by other researchers.
