Success for fishy scientist

19.07.2002


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).

Im Focus: Neutron star merger directly observed for the first time

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event

On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...

Im Focus: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...

Im Focus: Cold molecules on collision course

Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.

How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...

Im Focus: Shrinking the proton again!

Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.

It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
