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.

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...

Glaciers might seem rather inhospitable environments. However, they are home to a diverse and vibrant microbial community. It’s becoming increasingly clear that they play a bigger role in the carbon cycle than previously thought.
A new study, now published in the journal Nature Geoscience, shows how microbial communities in melting glaciers contribute to the Earth’s carbon cycle, a...
