Research to be presented at the APS comparative physiology meeting in San Diego
As global populations rise, so does the demand for seafood. In developed nations, the health benefits of a diet high in fish and seafood are regularly touted. In developing nations, fish and seafood often comprise a large portion of the diet.
Aquaculture—farming of fishes, mollusks, crustaceans and plants in an aquatic environment—is a booming business (approximately $119 billion in the US in 2010) and the fastest growing form of global food production. It holds promise for both satisfying our taste for seafood and combatting global food insecurity.
Sarah Andrewartha et al. at CSIRO Integrated Sustainable Aquaculture Production and the University of Tasmania are studying oysters for clues into how environmental conditions and stressors affect their ability to grow and thrive.
“We’re remotely monitoring changes in oyster heart-rate and feeding behavior with small biosensors. The oysters wearing biosensors act as sentinels and provide real-time information on how oysters are responding to changing environmental conditions or farm stressors,” Dr. Andrewartha said. “They provide us with laboratory data that relate heart rate to overall energy use on-farm.”
Oysters are a popular target species for aquaculture and are farmed internationally. Determining how they respond to temperature, water depth and light levels could help improve understanding of how they and other animals raised through aquaculture will react to changing conditions and adapt to their environment.
Their research adds to the growing body of work focused on understanding the conditions that enable target aquaculture species to flourish.
Andrewartha will present the talk “Real-time physiology: Can it assist aquaculture productivity” at the American Physiological Society (APS) intersociety meeting “Comparative Approaches to Grand Challenges in Physiology” (October 5–8, 2014, in San Diego). “During my talk, I’ll discuss the need for biosensors in aquaculture, collection of ground-truth data and two applications where biosensors are currently being used on-farm,” she added.
APS jointly hosts this intersociety meeting with the Society for Experimental Biology, Society for Integrative and Comparative Biology, Australian and New Zealand Society for Comparative Physiology and Biochemistry, Canadian Society of Zoologists, Crustacean Society and International Society for Neuroethology.

Physiology is the study of how molecules, cells, tissues and organs function in health and disease. Established in 1887, the American Physiological Society (APS) was the first U.S. society in the biomedical sciences field. The Society represents more than 11,000 members and publishes 14 peer-reviewed journals with a worldwide readership.

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).
Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...
Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.

Fiber-reinforced plastics (FRP) are frequently used in the aeronautic and automobile industry. However, the repair of workpieces made of these composite materials is often less profitable than exchanging the part. In order to increase the lifetime of FRP parts and to make them more eco-efficient, the Laser Zentrum Hannover e.V. (LZH) and the Apodius GmbH want to combine a new measuring device for fiber layer orientation with an innovative laser-based repair process.
Defects in FRP pieces may be production or operation-related. Whether or not repair is cost-effective depends on the geometry of the defective area, the tools...
