Genomic structure in Europeans dating back at least 36,200 years

Paleogenomics. Genomic structure in Europeans dating back at least 36,200 years.

The origin of contemporary Europeans remains contentious. We obtained a genome sequence from Kostenki 14 in European Russia dating from 38,700 to 36,200 years ago, one of the oldest fossils of anatomically modern humans from Europe. We find that Kostenki 14 shares a close ancestry with the 24,000-year-old Mal'ta boy from central Siberia, European Mesolithic hunter-gatherers, some contemporary w...

Fifty Years of Radiocarbon Dating

The history of radiocarbon dating through the 20th century is presented, focusing on the work of Willard F. Libby, who introduced radiocarbon dating in 1949, and its application during the following 50 years. Topics include an explanation of radiocarbon dating, by which the age of organic matter can be determined; difficulties Libby encountered in developing processes for accurate measurements;...

Looking back at 100 years of physiotherapy education in Australia.

Physiotherapy education in Australia has evolved, like the education of many other health care professions, from an apprenticeship often involving hospital-based training to the current day where it is a well recognised, highdemand degree program situated in the tertiary education sector (Higgs et al 1999). This remarkable transition has occurred in just 100 years. During this time, professiona...

Obesity and health in Europeans aged 50 years and older.

BACKGROUND Obesity is increasing globally across all population groups. Limited data are available on how obesity patterns differ across countries. OBJECTIVE To document the prevalence of obesity and related health conditions for Europeans aged 50 years and older, and to estimate the association between obesity and health outcomes across 10 European countries. METHODS Data were obtained fro...
