Retrieval of ancient DNA molecules is usually performed with special precautions to prevent DNA from researchers or the environment to get mixed in with the DNA from the fossil. However, many ancient fossils have been lying in museum collection for decades, and are contaminated with present-day human DNA before they enter the DNA-laboratory.

A new method presented in the online edition of the journal PNAS this week provides a solution to this problem. A statistical model for how degradation can be detected in DNA sequences is shown to be able to isolate DNA from ancient bones even when it is vastly outnumbered by modern-day DNA contamination--not in the laboratory, but in the computer.

"Many extremely interesting DNA data sets from ancient humans never see the light of day because of contamination. The idea behind this method was to change that," says Pontus Skoglund, lead author of the study and PhD in evolutionary genetics at Uppsala University.

To apply the method on a real-world fossil, Pontus Skoglund and his supervisor Mattias Jakobsson, professor at the Department of Evolutionary biology at Uppsala University and senior author of the study, teamed up with Johannes Krause and Svante Pbo at the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, who had a sequenced mitochondrial DNA from a Neandertal bone from Okladnikov cave in the Altai mountains in Siberia, but found that there was also modern human DNA in the bone. Application of the new method allowed the modern human DNA to be removed, and the complete mitochondrial genome of the Okladnikov individual showed that it was closely related to other Neandertals in Europe.

The drawback currently is that the DNA must be at least a thousand years old to allow separation from modern-day DNA, so studies of recent historical individuals still face many challenges.

"There are many really interesting ancient human remains that we can rescue from severe contamination with this method. And the method is not limited to Neanderthals, even remains of anatomically modern humans that are contaminated by modern-day humans can be rescued," says Mattias Jakobsson.

Scientists say two of the deadliest pandemics in history were caused by strains of the same plague and warn that new versions of the bacteria could spark future outbreaks.

Researchers found tiny bits of DNA in the teeth of two German victims killed by the Justinian plague about 1,500 years ago. With those fragments, they reconstructed the genome of the oldest bacteria known.

They concluded the Justinian plague was caused by a strain of Yersinia pestis, the same pathogen responsible for the Black Death that struck medieval Europe. The study was published online Tuesday in the journal, Lancet Infectious Diseases.

The two plagues packed quite a punch. The Justinian Plague is thought to have wiped out half the globe as it spread across Asia, North Africa, the Middle East and Europe. And the Black Death killed about 50 million Europeans in just four years during the 14th century.

"What this shows is that the plague jumped into humans on several different occasions and has gone on a rampage," said Tom Gilbert, a professor at the Natural History Museum of Denmark who wrote an accompanying commentary. "That shows the jump is not that difficult to make and wasn't a wild fluke."

The plague is usually spread to humans by rodents whose fleas carry the bacteria.

"Humans are infringing on rodents' territory, so it's only a matter of time before we get more exposure to them," Gilbert said.

Still, he and other experts doubted a modern plague epidemic would be as devastating.

"Plague is something that will continue to happen but modern-day antibiotics should be able to stop it," said Hendrik Poinar, director of the Ancient DNA Centre at McMaster University in Canada, who led the new research. He said about 200 rodent species carry the plague and could potentially infect other animals or humans.

Poinar warned that if the plague transforms into an airborne version which can happen if the bacteria reaches the lungs and its droplets are spread by coughing it would be much harder to snuff out. That type of plague can kill people within 24 hours of being infected.
