The Australian dingo descends from domesticated dogs that people from Southeast Asia brought with them to Australia some 5,000 years ago. Genetic studies indicate that it is probably a matter of a single occasion and a very small number of dogs.
The story begins when a few domestic dogs originally originating from East Asia, jump ashore from a boat. “No matter how you get to Australia, you have to travel across open seas for at least 50 km-a journey no large land-based animal has ever undertaken without human assistance, as far as we know. Therefore, there is good reason to believe that the ancestors of the dingo jumped ashore in Australia together with people who went there by boat,” says Peter Savolainen at the Royal Institute of Technology, Stockholm, Sweden, who has directed the work.
The study also shows that the dingo has been genetically isolated for at least 3,500 years and therefore constitutes a unique vestige that has preserved the appearance of early domesticated dogs. The results answer a question many researchers have posed about the yellow wild dog in Australia and what it really is. The study is now being published in the prestigious scientific journal Proceedings of the National Academy of Sciences of the USA. The article is being pre-published this week at PNAS Online Early Edition.

On the way to an intelligent laboratory, physicists from Innsbruck and Vienna present an artificial agent that autonomously designs quantum experiments. In initial experiments, the system has independently (re)discovered experimental techniques that are nowadays standard in modern quantum optical laboratories. This shows how machines could play a more creative role in research in the future.

For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.
Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...
At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.
No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.
Multiferroic materials show magnetically driven ferroelectricity. They are attracting increasing attention because of their fascinating properties such as...
