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.

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
