A couple of weeks ago we reported on research from the University of Nottingham that showed that being kind or altruistic was attractive to both sexes. Now more research, this time from the University of Rochester, published online today in the Journal of Personality and Social Psychology, shows that males are not only more attracted to women wearing red, but that they are also more likely to spend more money while out on a date. What's more, men are completely unaware of the influence of the colour red.

Forget perfect pecs, bulging biceps and sexy sixpacks - who needs them? Just make sure you get seen helping old ladies across the road, giving up your seat on the bus and helping your psychology teacher whenever you possibly can and the ladies (or gents) will be falling at your feet. According to new research from Nottingham University, being altruistic or selfless can be sexually attractive to both sexes.

The probability of someone cheating during the course of a relationship varies between 40 and 76 percent. "It's very high," says Geneviève Beaulieu-Pelletier, PhD student at the Université de Montréal's Department of Psychology.
