Australian scientists have produced a new high-speed welding technology that slashes hours from traditional joining of corrosion-resistant metals.

The Keyhole Welding process has been developed jointly by the Cooperative Research Centre for Welded Structures and CSIRO Elaborately Transformed Metals at Woodville in Adelaide, South Australia.

CSIRO’s Dr Ted Summerville says, ’This is a breakthrough, high-quality solution to the limited penetration of conventional TIG welding’.

11.8T HP supercomputer with Intel Itanium2 processors running Linux reaches full operations.

The Department of Energy’s Pacific Northwest National Laboratory is now home to the United States’ fastest operational unclassified supercomputer. The laboratory’s 11.8 teraflops industry-standard HP Integrity system came to full operating power this week, marking the next advance in high-performance computing designed to enable new insights in the environmental and molecular sciences, includ

Three Johns Hopkins researchers propose, for the first time, that HIV and other retroviruses can use a Trojan horse style of infection, taking advantage of a cloak of human proteins to sneak into cells.

The hypothesis explains 20 years of perplexing observations and suggests new ways to reduce HIV transmission and treat HIV infection, but it also implies that existing approaches to developing vaccines against HIV won’t work. A description of the hypothesis and its supporting evidence a

The Internet and the mail proved to be good aids in tracing chlamydia among young men. The results of an acclaimed project at Umeå University in Sweden are now being published in the September issue of the journal Eurosurveillance. With this method, 39 percent (396 of 1,016 interviewees), which is the highest published participation rate ever in a chlamydia screening of young men.

The project, being run by the researching general practitioner Daniel Novak together with his thesis director Ro

Scientists have successfully produced the most efficient light bulb ever – but on the microscopic scale. Researchers at Trinity College, Dublin have discovered a technique which significantly improves the output of light from quantum dots, and also allows their light to be focussed and manipulated easily. Their findings are published today in the Institute of Physics journal Semiconductor Science and Technology.
