Impatience and hostility--two hallmarks of the "type A" behavior pattern--increase young adults long-term risk of developing high blood pressure, according to a study funded by the National Heart, Lung, and Blood Institute (NHLBI), part of the National Institutes of Health. Further, the more intense the behaviors, the greater the risk.
However, other psychological and social factors, such as competitiveness, depression, and anxiety, did not increase hypertension risk. The research appears in the October 22/29, 2003, issue of The Journal of the American Medical Association. It was conducted by scientists at the Northwestern University Feinberg School of Medicine in Chicago, the University of Pittsburgh in PA, the University of Alabama at Birmingham, and the Birmingham Veterans Affairs Medical Center.
The research is the first prospective study to examine as a group the effects of key type A behaviors, depression, and anxiety on the long-term risk for high blood pressure. Earlier studies had mostly looked at individual psychological and social behaviors, and found conflicting results.

Physicists working with researcher Oriol Romero-Isart devised a new simple scheme to theoretically generate arbitrarily short and focused electromagnetic fields. This new tool could be used for precise sensing and in microscopy.
Microwaves, heat radiation, light and X-radiation are examples for electromagnetic waves. Many applications require to focus the electromagnetic fields to...
Strong light-matter coupling in these semiconducting tubes may hold the key to electrically pumped lasers
Light-matter quasi-particles can be generated electrically in semiconducting carbon nanotubes. Material scientists and physicists from Heidelberg University...
Fraunhofer IPA has developed a proximity sensor made from silicone and carbon nanotubes (CNT) which detects objects and determines their position. The materials and printing process used mean that the sensor is extremely flexible, economical and can be used for large surfaces. Industry and research partners can use and further develop this innovation straight away.
At first glance, the proximity sensor appears to be nothing special: a thin, elastic layer of silicone onto which black square surfaces are printed, but these...
3-D shape acquisition using water displacement as the shape sensor for the reconstruction of complex objects
A global team of computer scientists and engineers have developed an innovative technique that more completely reconstructs challenging 3D objects. An ancient...
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...
