New methods of detecting Salmonella in pork meat processing

2014-07-24
(Press-News.org) Traditional methods of characterising and detecting bacteria are often slow and time-consuming. Therefore, development of new methods of characterising and detecting illness-causing microorganisms is very important for improving food safety.

Trine Hansen, PhD student at the National Food Institute, has studied new methods of characterising Salmonella in pork meat processing and detecting unknown bacteria in water, feed and food samples.

The research project has given a better understanding of which factors in pork meat processing may contribute to the development of more appropriate processing environments, which can limit the occurrence of Salmonella.

Furthermore, a method based on concentration and sequencing of parts of the genome for all microorganisms present in e.g. a water sample was also tested, enabling researchers to find not only the microorganisms they are specifically looking for. This method was tested on B. cereus in water samples and can be used for discovering bacterial contamination in e.g. foodborne outbreaks where the contamination source is unknown.

Chemist develops X-ray vision for quality assurance

2014-07-24
It is seldom sufficient to read the declaration of contents if you need to know precisely what substances a product contains. In fact, to do this you need to be a highly skilled chemist or to have genuine X-ray vision so that you can look directly into the molecular structure of the various substances. Christian Grundahl Frankær, a Postdoc at DTU Chemical Engineering, is almost both, as he has developed a method that allows him to use X-rays to look deep into biological samples. The 'Fingerprints' of a Substance The technique is called 'powder diffraction' and involves ...

Unleashing the power of quantum dot triplets

Unleashing the power of quantum dot triplets
2014-07-24
Quantum computers have yet to materialise. Yet, scientists are making progress in devising suitable means of making such computers faster. One such approach relies on quantum dots—a kind of artificial atom, easily controlled by applying an electric field. A new study demonstrates that changing the coupling of three coherently coupled quantum dots (TQDs) with electrical impulses can help better control them. This has implications, for example, should TQDs be used as quantum information units, which would produce faster quantum computers due to the fact that they would be ...

Tempting people to move for work takes more than dollars

2014-07-24
Sufficient financial inducements are one way of encouraging people to move to regional Australia for jobs, but other factors also play a part, according to a new report. Moving workers from a region with high unemployment to a region with many job vacancies is an important aspect of labour markets. The Commission of Audit recently advised the government to "force" long-term unemployed people who are single and between the ages of 22 and 30 to move to areas of higher employment if they have been on the dole for 12 months. Researchers from Monash and Deakin Universities ...

Study reveals medical students believe health policy education is improving

2014-07-24
Philadelphia – Students graduating from U.S. medical schools in 2012 feel they've received a better education in health policy issues than graduates surveyed in 2008, according to a multi-center study led by the Perelman School of Medicine at the University of Pennsylvania, and published online this month in Academic Medicine. The study applied a new framework for teaching and evaluating perceptions of training in health policy, first proposed by the authors in a 2011 perspective published in the New England Journal of Medicine. "Our prior work found that for nearly a ...

Discovery is key to metal wear in sliding parts

Discovery is key to metal wear in sliding parts
2014-07-24
WEST LAFAYETTE, Ind. – Researchers have discovered a previously unknown mechanism for wear in metals: a swirling, fluid-like microscopic behavior in a solid piece of metal sliding over another. The findings could be used to improve the durability of metal parts in numerous applications. "Wear is a major cause of failure in engineering applications," said Srinivasan Chandrasekar, a Purdue University professor of industrial engineering and materials engineering. "However, our findings have implications beyond wear itself, extending to manufacturing and materials processing." The ...

Highest-precision measurement of water in planet outside the solar system

Highest-precision measurement of water in planet outside the solar system
2014-07-24
A team of astronomers using NASA's Hubble Space Telescope have gone looking for water vapour in the atmospheres of three planets orbiting stars similar to the Sun – and have come up nearly dry. The three planets, HD 189733b, HD 209458b, and WASP-12b, are between 60 and 900 light-years away, and are all gas giants known as 'hot Jupiters.' These worlds are so hot, with temperatures between 900 to 2200 degrees Celsius, that they are ideal candidates for detecting water vapour in their atmospheres. However, the three planets have only one-tenth to one-thousandth the ...

Wives with more education than their husbands no longer at increased risk of divorce

2014-07-24
WASHINGTON, DC -- For decades, couples in which a wife had more education than her husband faced a higher risk of divorce than those in which a husband had more education, but a new study finds this is no longer the case. "We also found that couples in which both individuals have equal levels of education are now less likely to divorce than those in which husbands have more education than their wives," said Christine R. Schwartz, lead author of the study and an associate professor of sociology at the University of Wisconsin-Madison. "These trends are consistent with ...

Warning: Birthdays can be bad for your health

2014-07-24
New research has found that birthday-related drinking is associated with upsurges in hospital admissions among young people. This study of drinking behaviour in Ontario, Canada is published online today in the scientific journal Addiction. Researchers, led by University of Northern British Columbia Associate Professor of Psychiatry Dr. Russ Callaghan, analysed records from all hospital admissions in Ontario over a five-year period (2002-07) involving people aged 12 to 30 years. They discovered that during the week in which Ontarians turned 19 – the legal drinking age ...

Experiments prove 'stemness' of individual immune memory cells

2014-07-24
The immune system has evolved to recognize and respond to threats to health, and to provide life-long memory that prevents recurrent disease. A detailed understanding of the mechanism underlying immunologic memory, however, has remained elusive. Since 2001, various lines of research have converged to support the hypothesis that the persistence of immune memory arises from a reservoir of immune cells with stem-cell-like potential. Until now, there was no conclusive evidence, largely because experiments could only be carried out on populations of cells. This first strict ...

Newly discovered gut virus lives in half the world's population

2014-07-24
Odds are, there’s a virus living inside your gut that has gone undetected by scientists for decades. A new study led by researchers at San Diego State University has found that more than half the world’s population is host to a newly described virus, named crAssphage, which infects one of the most common types of gut bacteria, Bacteroidetes. This phylum of bacteria is thought to be connected with obesity, diabetes and other gut-related diseases. The research appears today in Nature Communications. Robert A. Edwards, a bioinformatics professor at SDSU, and his colleagues ...
