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.

In a recent publication in the renowned journal Optica, scientists of Leibniz-Institute of Photonic Technology (Leibniz IPHT) in Jena showed that they can accurately control the optical properties of liquid-core fiber lasers and therefore their spectral band width by temperature and pressure tuning.
Already last year, the researchers provided experimental proof of a new dynamic of hybrid solitons– temporally and spectrally stationary light waves resulting...

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.
Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...
The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.
Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.
An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.
Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...
