Men are from Mars and women are from Venus, or so we’ve been told, and when it comes to jealousy this is especially true. Men, psychologists have long contended, tend to care more about sexual infidelity while women usually react more strongly to emotional infidelity. This view has long been espoused by evolutionary psychologists who attribute these gender differences to natural selection, which, they say, encouraged the sexes to develop different emotional reactions to jealousy.
However, a recent research paper published in Personality and Social Psychology Review by Christine Harris, a psychologist with the Center for Brain and Cognition at the University of California, San Diego, casts serious doubts on this view of gender differences on jealousy and argues that more men and women appear to view sexual and emotional jealousy in the same light.
“This research has found that the evolutionary theory of jealousy just does not hold up to rigorous academic scrutiny,” said Harris. “A thorough analysis of the different lines of research which espoused this point of view raises serious doubts about how much of a sex difference actually exists. It is entirely possible that natural selection shaped the two sexes to be more similar rather than different.”

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...
