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).

The more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.

A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.
The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...
At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.
At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
