There is no association between two specific personality traits – neuroticism and extroversion – and cancer, according to a new study, one of the largest prospective twin studies to examine this issue. The study, published in the March 1, 2005 issue of CANCER (http://www.interscience.wiley.com/cancer-newsroom), a peer-reviewed journal of the American Cancer Society, also finds no evidence that personality traits indirectly lead to cancer through behavioral factors, such as smoking.
Personality traits are popularly cited as risk factors for cancer. Some studies have gone so far as to suggest that two traits in particular, neuroticism and extroversion, may be such risk factors. Scientists have hypothesized that a high degree of extroversion and low degree of neuroticism are associated with an increased risk. Some studies further show that these personality traits influence known risk behaviors that would explain the increased cancer risk. However, other studies, some with larger study populations and better study designs, have found no such associations.
Pernille Hansen, M.A. of the Department of Psychosocial Cancer Research at the Institute of Cancer Epidemiology in Copenhagen, Denmark led a team of investigators who reviewed cancer history, health behavior, and personality trait data collected from 29,595 Swedish twins enrolled in the Swedish Twin Registry. These patients were born between 1926-1958 and were followed an average 25 years.

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...
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...
