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.

A new manufacturing technique uses a process similar to newspaper printing to form smoother and more flexible metals for making ultrafast electronic devices.
The low-cost process, developed by Purdue University researchers, combines tools already used in industry for manufacturing metals on a large scale, but uses...
For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
