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.”

Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...

When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure
Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
