Age, gender, body size are better predictors of aortic aneurysm; genetics are likely important
Contrary to long-accepted conventional wisdom and to current theories, high blood pressure and other risk factors for plaque buildup are not major factors in the dangerous ballooning of blood vessels near the heart, according to a Mayo Clinic study published in the Journal of the American College of Cardiology this week.
"Atherosclerotic plaques and the risk factors that cause them, including hypertension, classically have been considered important potential causes of the expansion of the aorta," says Bijoy Khandheria, M.D., a Mayo Clinic cardiologist and study author. "Intuitively, it makes sense that high blood pressure would stretch the vessel walls and make them more likely to become enlarged. This study shows that while these risk factors are highly important in a host of diseases and conditions, they are bit players when it comes to causing the dilatation of the aorta that can lead to aneurysm."

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.
To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
