The Marine Mammal Center is seeing a large number of leptospirosis cases in California sea lions this year and is leading a study to determine when and why the sea lions contract this disease.
Every four to five years, the Center sees a surge in the number of sea lions admitted as a result of this bacterial infection that affects the kidneys and can be lethal for patients. The current research will focus on the factors contributing to these cycles of disease so that scientists will have an understanding of how the disease spreads and what the risks are to sea lions and other animals. Recently, the Center began taking blood samples, tagging, and releasing wild juvenile California sea lions in the Bay Area as part of the new research study.
"The blood samples our team will collect from wild California sea lions will help them determine kidney function and exposure rates among these animals," said Dr. Jeffrey Boehm, Executive Director at The Marine Mammal Center. "The data will also help us understand more about the susceptibility of sea lions in the population during an epidemic and clarify the relationship between the stranded sea lions with leptospirosis we see here at the Center and those that are susceptible in the population."
Leptospirosis epidemics were first documented in California sea lions in the early 1970s and are caused by spiral shaped bacteria called leptospires. Many different animal species, including humans, carry the bacterium which can leech into water or soil and survive there for weeks to months. Humans and animals can become infected through contact with contaminated urine, water, or soil. If not treated, the patient can develop kidney damage, meningitis, liver failure, and respiratory distress. The Marine Mammal Center advises beach goers and their dogs to stay away from marine mammals they may encounter on beaches and to call the Center's 24-hour response line at (415) 289-SEAL should they come across any marine mammal in distress.
Collaborators in this new study include the National Oceanic Atmospheric Administration, University of California Los Angeles, University of California at Davis, Penn State University and the National Animal Disease Center in Ames, Iowa.

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.
Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...
Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.
As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...
Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.
With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...

Germany counts high-precision manufacturing processes among its advantages as a location. It’s not just the aerospace and automotive industries that require almost waste-free, high-precision manufacturing to provide an efficient way of testing the shape and orientation tolerances of products. Since current inline measurement technology not yet provides the required accuracy, the Fraunhofer Institute for Laser Technology ILT is collaborating with four renowned industry partners in the INSPIRE project to develop inline sensors with a new accuracy class. Funded by the German Federal Ministry of Education and Research (BMBF), the project is scheduled to run until the end of 2019.
