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.

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...

In the race to produce a quantum computer, a number of projects are seeking a way to create quantum bits -- or qubits -- that are stable, meaning they are not much affected by changes in their environment. This normally needs highly nonlinear non-dissipative elements capable of functioning at very low temperatures.
In pursuit of this goal, researchers at EPFL's Laboratory of Photonics and Quantum Measurements LPQM (STI/SB), have investigated a nonlinear graphene-based...
