CSIRO marine scientists have developed a technique that gives new hope in the battle to stop the spread of aquatic pests
"What we have is a probe acting as a magnet to detect a needle in a haystack," says Dr Jawahar Patil, who designed the technique which has been successfully tested in Australia.
The new DNA probe involves seawater sample extraction of DNA, and amplification of a target specific "DNA signature or fingerprint" to identify the presence of pest species in water.
"Looking for larval pests in water samples is like looking for a needle in a hay stack and the probes give us a new set of eyes for the marine environment," said Dr Jawahar Patil, who led the research team, including Dr Bax, Mr Bruce Deagle and Dr Rasanthi Gunasekera, all from CSIRO.
Development of the probes has been undertaken in partnership with shipping and port industries and the Australian Quarantine and Inspection Service. It has been funded by the Commonwealth Governments Natural Heritage Trust and the Victorian Government as part of the Port of Hastings National trial of ballast water management.

The world's highest gain high power laser amplifier - by many orders of magnitude - has been developed in research led at the University of Strathclyde.
The researchers demonstrated the feasibility of using plasma to amplify short laser pulses of picojoule-level energy up to 100 millijoules, which is a 'gain'...
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.
The quantum computer has fuelled the imagination of scientists for decades: It is based on fundamentally different phenomena than a conventional computer....
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...
