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.

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).
Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...
Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.
The cells of the mouth, nose and intestinal mucosa produce large quantities of a chemical called sialic acid. Many bacteria possess a special transport system...

Fiber-reinforced plastics (FRP) are frequently used in the aeronautic and automobile industry. However, the repair of workpieces made of these composite materials is often less profitable than exchanging the part. In order to increase the lifetime of FRP parts and to make them more eco-efficient, the Laser Zentrum Hannover e.V. (LZH) and the Apodius GmbH want to combine a new measuring device for fiber layer orientation with an innovative laser-based repair process.
Defects in FRP pieces may be production or operation-related. Whether or not repair is cost-effective depends on the geometry of the defective area, the tools...
