The 2012 growing season was considered an average year on the Canadian Prairies, "but we still had a summer water deficit, and it is that type of condition we are trying to work with," said Scott Chang, a professor of soil science in the University of Alberta's Department of Renewable Resources in Edmonton, Canada.
Chang teamed with fellow crop scientist Anthony Anyia of Alberta Innovates – Technology Futures in 2006, following a severe drought in 2002 that dropped average crop yield in Alberta by about half.
They are exploring the genetic makeup of barley and how the grain crop—a Canadian staple used for beer malt and animal feed—can be made more efficient in its water use and more productive. One of their latest studies, published in the journal Theoretical and Applied Genetics, explores how to increase yield in barley crops while using less water.
By studying the carbon isotope compositions of barley plants and their relationship with water-use efficiency, the researchers developed tools that plant breeders can use to improve selection efficiency for more water-efficient varieties. The latest findings stem from an ongoing collaboration that is ultimately aimed at bringing farmers a more stable breed of the plant that has less reliance on water and is less vulnerable to climate change.To arrange an interview or for a link to the study contact:

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....
Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.
Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
