One of the really big challenges in anthropology is to date accurately the arrival of humans in the different continents. New results, to be published in a forthcoming issue of the Journal of Quaternary Science, show that humans arrived in Australia a lot earlier than was previously thought.
It is generally argued that humans evolved in Africa and then spread out over the other continents progressively through time, arriving in the most distant, such as Australasia, relatively recently. The conventional view, based on radiocarbon dating, is that the earliest human colonisation of Australia occurred only around 40,000 years ago. New evidence, published in the Journal of Quaternary Science, pushes the arrival of the first humans in Australia back by as much as 15,000 years, to between 45,000 and 55,000 years ago.
Dr Chris Turney of Queen’s University, Belfast and Australian colleagues report evidence for extensive burning at this time in North Queensland which is independent of any climate change. Using new techniques for radiocarbon dating lake sediments, Dr Turney and his colleagues attribute these extensive fires to human activity.

Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
