"The good news is that we have found no evidence that Asian carp are widespread in the Great Lakes basin, despite extensive surveys in Southern Lake Michigan and parts of lakes Erie and St Clair," Christopher Jerde, the paper's lead author and a scientist at the University of Notre Dame, said. "Looking at the overall patterns of detections we remain convinced that the most likely source of Asian carp DNA is live fish."
"When we first discovered DNA from Asian carp at the Calumet Harbor and Port of Chicago, we were concerned that Asian carp may already be widespread in the Great Lakes," Andrew Mahon, co-author and assistant professor at Central Michigan University, said . "But because of our collaborations with State and Federal partners, we now have a better picture of the Asian carp distribution, and we are optimistic that with continued vigilance, it will be possible to prevent Asian carp becoming established in the Great Lakes."
This work is part of a Great Lakes Restoration Initiative project funded through the US Fish and Wildlife Service to help develop a program of invasive species surveillance of the Great Lakes. This research grew out of a formal partnership between the University of Notre Dame and The Nature Conservancy, one of the world's largest and most established conservation organizations. The mission of Notre Dame's Environmental Change Initiative is to conduct innovative research that helps to solve complex environmental problems regarding invasive species, land use, and climate change, focusing on their impacts on water resources.
The Nature Conservancy is a leading conservation organization working to protect the most ecologically important lands and waters around the world for nature and people.

The Institute for Great Lakes Research (IGLR) at Central Michigan University is committed to promoting and facilitating collaborative research and education on the Great Lakes. IGLR partners with other institutions and agencies to leverage our expertise and training and takes a multidisciplinary approach to understanding the complex environmental issues affecting the Great Lakes basin.
The Canadian Journal of Fisheries and Aquatic Sciences (CJFAS) is one of the world's top fisheries journals and is the primary publishing vehicle for the multidisciplinary field of aquatic sciences. It publishes perspectives, discussions, articles, and rapid communications, relating to current research on cells, organisms, populations, ecosystems, or processes that affect aquatic systems. The journal seeks to amplify, modify, question, or redirect accumulated knowledge in the field of fisheries and aquatic science. CJFAS is published by Canadian Science Publishing and is part of the prestigious NRC Research Press journal collection.

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.
