Paleogeneticist Dr. Johannes Krause (University of Tübingen, Germany) and colleagues were interested in the origin of tuberculosis (TB) in the Americas. Since strains of TB found in the Americas are related to strains found in Europe, prior theories held that Spaniards may have introduced it to the Americas while colonizing South America.  The problem with…

A new study published in the American Journal of Physiology presents data suggesting that birds do not carry a specific anti-inflammatory protein critical for keeping inflammation under control in mammals, reptiles and amphibians. The specific protein is tristetraprolin (TTP). It functions mainly by inhibiting key mediators of inflammation in the body, such as tumor necrosis…

Ancient Horse Genome Sequenced

Researchers have successfully created a draft sequence of the complete genome of a 700,000 year old horse from a bone fragment extracted from permafrost in the Yukon Territory (Canada). This is the oldest specimen ever sequenced by almost 10-fold. Prior sequencing of the whole genome from a hominid from Siberia who lived 80,000 years ago…
