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).

Strong light-matter coupling in these semiconducting tubes may hold the key to electrically pumped lasers
Light-matter quasi-particles can be generated electrically in semiconducting carbon nanotubes. Material scientists and physicists from Heidelberg University...
Fraunhofer IPA has developed a proximity sensor made from silicone and carbon nanotubes (CNT) which detects objects and determines their position. The materials and printing process used mean that the sensor is extremely flexible, economical and can be used for large surfaces. Industry and research partners can use and further develop this innovation straight away.
At first glance, the proximity sensor appears to be nothing special: a thin, elastic layer of silicone onto which black square surfaces are printed, but these...
3-D shape acquisition using water displacement as the shape sensor for the reconstruction of complex objects
A global team of computer scientists and engineers have developed an innovative technique that more completely reconstructs challenging 3D objects. An ancient...
Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.
To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
