Scallops, oysters and mussels - the best of fare Scotland`s kitchens have resulted in a top Parisian award for a researcher from the University of Dundee. Matthew Gubbins is not a chef but a scientific expert on toxicity in shellfish.
Matthew (26) has scooped the Daniel Jouvance award for his work on how shellfish become toxic and then lose their toxicity again in the sea. Identifying these processes will allow the industry to monitor more closely when shellfish are non-toxic , ready for harvest and consumable.
The Daniel Jouvance scientific award is given annually to two scientists under the age of 30 working in marine biochemistry. This is yet another young scientist success story for the School of Life Sciences which boasts eight winners of the Colworth medal for scientists under 36. Matthew will be presented with his award in Paris this October.
Matt Gubbins began researching how paralytic shellfish toxins (PST) might be metabolised in marine organisms as the subject of his PhD, at the Department of Biological Sciences, University of Dundee and Fisheries Research Services (FRS), Aberdeen. His initial studies identified an enzyme in the livers of salmon, which was increased in the presence of PST, suggesting it could play a role in metabolising these toxins. This enzyme (glutathione S-transferase) was studied both in salmon and bivalve shellfish, such as mussels, which were also found to contain increased levels of the enzyme when contaminated with PST. Another enzyme (sulphotransferase) in mussels was able to metabolise one of the PST toxins, but scallops, which are known to retain PST toxins for a longer period of time, did not demonstrate any evidence of being able to metabolise these toxins using such enzymes.
By studying the fate and effects of these natural compounds in fish and shellfish, Matt has established possible enzyme-level mechanisms for the detoxification of PST in fish and shellfish. This has advanced our understanding of the fate of these compounds in the marine environment and could open future possibilities for novel techniques of shellfish depuration (cleansing).

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....
