The award is endowed with 50,000 euros and will be given at the 58th Annual Meeting of the European Association for Animal production in Dublin from 26-29th August. The judging committee made special mention of his recent pioneering research to develop natural plant-based products as supplements for animal feeds.
Dr Wallace’s research career has focused on the mysterious world of the rumen. This is the large, four-chambered stomach which is a feature of animals such as cows and sheep (and is why these animals are called ruminants). The rumen is really a huge fermentation vat which houses billions of bacteria and several litres of fluid. In this gurgling chamber the rumen bugs break down the grass and other plant materials which the ruminants eat, but can’t digest without the help of the these bugs. The metabolism of the rumen bugs is vitally important to the health and productivity of ruminants and Dr Wallace is a world expert in this area.
Dr Wallace joined the Rowett Research Institute in 1976. He has published over 200 scientific papers and his expertise has taken him around the world to visit other laboratories and to give keynote talks at major scientific meetings. His work has always been of great interest to animal feedstuff manufacturers and to date he has worked with over 30 companies across Europe.
“Initially my research looked at how feed additives such as yeast worked, and I was also interested to discover the mechanism of action of antibiotics, which at one point were widely used in animal nutrition to promote growth. We found that these additives have an effect on the metabolism of the rumen bugs, and can have a large impact on the how the animals grow, and their productivity. Since 2006 growth-promoting antibiotics have been banned from the EU and so livestock producers need to find new ways to maintain similar production benefits to remain competitive against overseas producers, particularly in the USA, where the use of antibiotics is still legal.
“To address this issue, I have coordinated two large European projects, one of which is currently in progress. We are examining plants, plant extracts and other natural materials for their potential as safe alternatives to antimicrobials. We have been successful in identifying plant materials that can improve nitrogen retention in ruminants, which basically means that the animals grow better and their urine is less polluting. In addition, we have found a type of chrysanthemum which helps to improve the fat composition of milk. The current project, called REPLACE, is conducting some animal trials on the most promising plant materials collected during the first project. Early results from some of the trials with early-weaned pigs look very interesting as the plant extracts seemed to help prevent the diarrhoea which these piglets are very prone to suffer from,” said Dr Wallace.Professor Morgan, Director of the Rowett Institute, said of the award:

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.
Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....
Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
