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.

Soft robots have a distinct advantage over their rigid forebears: they can adapt to complex environments, handle fragile objects and interact safely with humans. Made from silicone, rubber or other stretchable polymers, they are ideal for use in rehabilitation exoskeletons and robotic clothing. Soft bio-inspired robots could one day be deployed to explore remote or dangerous environments.
Most soft robots are actuated by rigid, noisy pumps that push fluids into the machines' moving parts. Because they are connected to these bulky pumps by tubes,...
Researchers at TU Graz are working together with European partners on new possibilities of measuring vehicle emissions.
Today, air pollution is one of the biggest challenges facing European cities. As part of the Horizon 2020 research project CARES (City Air Remote Emission...
Over the next three years, researchers from the Vrije Universiteit Brussel, University of Cambridge, École Supérieure de Physique et de Chimie Industrielles de la ville de Paris (ESPCI-Paris) and Empa will be working together with the Dutch Polymer manufacturer SupraPolix on the next generation of robots: (soft) robots that ‘feel pain’ and heal themselves. The partners can count on 3 million Euro in support from the European Commission.
Soon robots will not only be found in factories and laboratories, but will be assisting us in our immediate environment. They will help us in the household, to...
Scientists at the University of Leeds have created a new form of gold which is just two atoms thick - the thinnest unsupported gold ever created.
The researchers measured the thickness of the gold to be 0.47 nanometres - that is one million times thinner than a human finger nail. The material is regarded...
An international team of scientists involving the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) in Hamburg has unraveled the light-induced electron-localization dynamics in transition metals at the attosecond timescale. The team investigated for the first time the many-body electron dynamics in transition metals before thermalization sets in. Their work has now appeared in Nature Physics.
The researchers from ETH Zurich (Switzerland), the MPSD (Germany), the Center for Computational Sciences of University of Tsukuba (Japan) and the Center for...
