The amount of sex couples have doesn’t necessarily translate to marital or personal bliss, and as a new study suggests, less-frequent sex might make couples happier.

The study, published in Social Psychology and Personality Science, debunks the long-cherished, pop-culture-reinforced notion that more sex equates to more happiness.

“For people in relationships, sexual frequency is no longer significantly associated with well-being at a frequency greater than once a week,” wrote the researchers, led by Amy Muise, of the University of Toronto, Mississauga.

Muise and her colleagues found through three separate surveys that most Americans consider five rounds of sexual activity a month to be sufficient, and that the relationship between happiness and sex had more of a curvilinear tinge to it, as opposed to a strictly linear composition. People who were having sex less than once a month were less happy than those having sex once a week, but the overall returns for happiness diminished as frequency increased.

One survey contained answers from 25,000 respondents compiled throughout 1989 to 2012. Nearly all the data remained static across gender, race, and ethnicity.

Not examined in-depth was how these findings would hold for people outside of relationships. “Looking at when and for whom having more frequent sex when single is beneficial is another area ripe for future research,” Muise told The Guardian.

Muise and her team aren’t the first scientists to dampen the expectation that lots of sex leads to a better life. Researchers at Carnegie Mellon University have done the same, publishing a similar study last July, in which two survey groups were split up and asked to alter their respective sex lives. The first group was asked to have more sex, while the second didn’t change their sexual routines.

The first group reported far less happiness than the second.

When your profession is studying ancient temples and cultural artifacts, you need a toolbox that matches the magnitude of the job. Brushes, buckets, and sieves have long been the foundation of an archaeologist’s work, but today, those essentials are paired with groundbreaking technology to deepen human understanding of our collective past.

For months, a team of researchers in San Diego have been watching genetically engineered mice work out.

The scientists are trying uncover the effects of a tiny gene that hasn’t worked properly in humans for millions of years. The mice recently finished their workouts and the results, published in Proceedings of the Royal Society B, suggest that this genetic detail not only makes humans great runners, it could potentially play an important role in our own evolution.

If you’re a housefly, life comes at you fast: Within days of being born, you mature, hatch your babies and die having served your evolutionary purpose. But we humans tend to take as many as 100 years to undergo the same process. Now, a new study featured on the cover of Molecular Biology Evolution provides new insight into why humans are able to live as long as we do. Researchers identified a handful of genes that were so strongly conserved millions of years ago, they influence our lifespans even today.

The yoga class adage of being fully in the moment while you contort your body on a mat may seem like a big ask for the less-flexible among us. However, a recent study spearheaded by a team at Wake Forest Medical School has compelling evidence that if you surrender to what may seem like a clichéd advice, you could reap some wonderful benefits, including the ability to feel less pain.

A cherry-like fruit that grows deep in the Amazon jungle has the potential to help battle the North American obesity crisis, suggests new research published in Gut. In the study, an extract from camu camu, a round, red, super-tart fruit, reduced obesity in mice whose diets went otherwise unchanged. The fruit, it appears, reverses weight gain from the inside out.
