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.

University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.
Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.
Study published in the journal ACS Applied Materials & Interfaces is the outcome of an international effort that included teams from Dresden and Berlin in Germany, and the US.
Scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) together with colleagues from the Helmholtz-Zentrum Berlin (HZB) and the University of Virginia...
Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.
The typical wavelength of light interacting with an object of the microcosm scales with the size of this object. For atoms, this ranges from visible light to...
Stable joint cartilage can be produced from adult stem cells originating from bone marrow. This is made possible by inducing specific molecular processes occurring during embryonic cartilage formation, as researchers from the University and University Hospital of Basel report in the scientific journal PNAS.
Certain mesenchymal stem/stromal cells from the bone marrow of adults are considered extremely promising for skeletal tissue regeneration. These adult stem...
