A diagnosis of cancer carries such emotional upheaval that a persons prolonged feelings of depression can eat away at the possibility for long-term survival. In a new study of cancer patients published in the current issue of Psychosomatic Medicine, researchers have found that peoples lives were more likely to be cut short when they had more symptoms of depression.
University of Rochester psychologist Kirk Warren Brown and co-authors used a number of demographic, medical, cancer treatment, and psychological factors to predict longevity in a group of 205 cancer patients over a 10-year period.
Among the psychological factors examined in this study on psychological distress and cancer survival were a variety of indicators of emotional state and coping, including positive and negative mood, anxiety, stress, sense of control, and depressive symptoms. After accounting for the effects of known demographic, medical risk, and cancer treatment factors, results showed that symptoms of depression were the most consistent psychological predictor of shortened survival.

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...
