Journal of Colloid and Interface Science | doi:10.1016/j.jcis.2014.10.008

If you have reason to celebrate this Valentine's Day, you may decide to mark the occasion with a bottle of bubbly. But what's the trick to stop it gushing over, and you losing valuable liquid? A study published in the Journal of Colloid and Interface Science has examined the effects of factors such as transport, exterior temperature and opening of the container, on the equilibrium of pressure and concentration of carbon dioxide in gas and liquid form inside a champagne bottle. Specifically, the researchers  looked at the consequences of shaking the bottle on pressure and found that, contrary to popular belief, shaking a bottle of champagne decreases the pressure inside.

The long and short of it; height doesn't matter!

The impact of dominance on partner's height preferences and height-related mate choices

Personality and Individual Differences | doi:10.1016/j.paid.2014.10.034

The phrase "tall, dark and handsome" is often used by women describing their ideal partner, but new research has now shown that height is not the be all and  end all when women come to settle down with someone. The study, published in Personality and Individual Differences, has shown that less dominant women tend to be more attracted to taller male partners, and more dominant women prefer shorter men relative to their own height. Surprisingly however,  this was not always reflected in their partner choice to father their children. This study suggests that there are many other factors that are considered when selecting the ideal partner to settle down with.

Personality and Individual Differences | doi:10.1016/j.paid.2014.11.042

Personality traits and individual differences are important in understanding various aspects of human sexuality and relationships. One-night stands, booty-calls,  and friends with benefits are all types of casual relationships, but what types of personalities seek casual relationships and which express an aversion? This study found that overall, men were more eager than women to engage in casual relationships. Both men and women with secure attitudes about love  expressed a distaste for casual relationships but those individuals with dishonest traits reported involvement in a variety of casual sex scenarios. Those who show conscientious characteristics are likely to make the steadiest romantic partners as they avoid one-night stands and look for serious romantic  relationships.

Journal of Experimental Psychology | doi:10.1016/j.jesp.2014.09.007

Evidence shows that it is women who are more likely to regain their partner's trust after repeatedly straying in a relationship.


The impact of porn on newlyweds

Computers in Human Behavior | doi:10.1016/j.chb.2014.11.077

Adjusting to marriage in its first year can be tough and the use of internet porn may do more damage to a relationship than good. A study published in Computers in Human Behavior has investigated the impact of porn on newlyweds. The study showed that, a husbands' use of porn hinders their adjustment to marriage. When a husband shows sexual satisfaction, this decreases their wives' use of porn over the course of a year. The research also found that wives use porn to spice up their  sex life when husbands show they are not satisfied, and when seeking relationship quality.
