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.

Physicists from the University of Würzburg have designed a light source that emits photon pairs. Two-photon sources are particularly well suited for tap-proof data encryption. The experiment's key ingredients: a semiconductor crystal and some sticky tape.
So-called monolayers are at the heart of the research activities. These "super materials" (as the prestigious science magazine "Nature" puts it) have been...
Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.
This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
