Asian dating chronicles

By means of a systematic analysis of the annals of three different years, it provides a critical evaluation of published and manuscript primary sources, identifies the nature of the interdependence amongst authors, and sheds new light on the craft of historical writing.

This book fills a critical gap in the scholarship on Mamluk historiography.

The syndicate, based in an Asian country, was understood to have been in operation for about six months and controlled by a gang of men who pose as female university students or young office workers and search for targets using mobile dating apps.

“Fraudsters usually claim they are visa students or office workers from Japan, South Korea or mainland China and befriend targets before revealing they also work as part-time compensated dating girls to earn pocket money,” one police source said.

"The radiocarbon dating technique may significantly underestimate the age of sediment for samples older than 30,000 years,” said the authors of the report from the Chinese Academy of Sciences and Germany’s Leibniz Institute for Applied Geophysics.

“Thus it is necessary to pay [special] attention when using such old carbon data for palaeoclimatic or archaeological interpretations," they added.

"The carbon-14-based mega-lake hypothesis was even incorporated into modelling work to interpret regional climate dynamics,” the paper reported.

Radiocarbon dating, which is used to calculate the age of certain organic materials, has been found to be unreliable, and sometimes wildly so - a discovery that could upset previous studies on climate change, scientists from China and Germany said in a new paper.

Their recent analysis of sediment from the largest freshwater lake in northeast China showed that its carbon clock stopped ticking as early as 30,000 years ago, or nearly half as long as was hitherto thought.

Prior to that, they had to depend on more rudimentary and imprecise methods, such as counting the number of rings on a cross-section of tree trunk.

This all changed in the 1940s when US chemist Willard Libby discovered that carbon-14, a radioactive isotope, could be used to date organic compounds.
