"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.

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
