Early results of a UK study published online today by THE LANCET (Wednesday 25 August 2004) suggest that a surgical procedure to repair aortic aneurysm that is less invasive than conventional open surgery could reduce death within a month of surgery by around two-thirds.
Abdominal Aortic Aneurysm (AAA) is a dangerous swelling of the abdominal aorta which has an increased chance of rupture if it is larger than 5•5cm—a majority of people die from ruptures. The cause of AAA is complex, including atherosclerosis,smoking, and a genetic predisposition.
Surgeons have perfected a new method for treating AAA’s over the past decade, called endovascular repair, or EVAR. In this procedure, 2 small incisions are made in the groin, and a graft is passed through the arteries under Xray control and fixed with a stent which holds the graft in place; this procedure is much less invasive than conventional surgery which requires a deep abdominal incision.

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.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
