People exercise quite a lot, society has access to diverse fresh fruits and vegetables and yet most economic, educational, and racial or ethnic groups have seen their obesity levels rise at similar rates since the mid-1980s, so there is no demographic correlation to obesity. Yet the social sciences draw maps to city parks and farmer's markets and claim more of those would keep people from getting fat, or tout that economic redistribution would lead to less fast food.

Cars, fast food, iPads, city living, even women in the work force - if it is something in culture, someone has implicated it. 

The Deadliest Catch details the work travails of Bering Sea crab fishermen, but African wives of fishermen may be having adventures of their own.

The authors of a recent paper estimated that up to 60% of men and 50% of women report extra-marital partnerships in their lifetime - and they believe those numbers are under-reported, especially among women, due to cultural constraints. In reality, range estimates are so broad as to be almost meaningless but even if it's 20% it's a lot.

An article in the feminist, scientific, peer-reviewed journal Psychology of Women Quarterly says that when women in developing countries own land, they are less likely to experience violence.

Psychologists Shelly Grabe, Rose Grace Grose and Anjali Dutt analyzed anecdotes Grabe cataloged by speaking with 492 women in Nicaragua and Tanzania in 2007 and 2009 respectively. 

Grabe wanted to show that the power dynamic between men and women changes when women own land and that gender-based violence against women drops with property ownership.  

"Women in both countries connected owning property to increased power and status within their communities and to having greater control within their relationships," the authors write.

The 1918 Flu Pandemic infected over 500 million people and killed up to 50 million. 

Scholars have analyzed the pandemic in two remote regions of North America, finding that despite their geographical divide, both regions had environmental, nutritional and economic factors that influenced morbidity during the pandemic.

By analyzing death records and community history, they found that both Labrador and Alaska were devastated by the 1918 pandemic. Beginning in January 1918 and lasting through December 1920, both regions experienced higher mortality rates than most other parts of the world—34 percent and 8 percent, respectively.

In 2014, drugs and alcohol are used primarily for pleasure and not to commune with nature or contact the spirit world.

In ancient times, opium poppies and hallucinogenic mushrooms were for gifted elites and their use went hand-in-hand with shamanistic belief systems and the sacred burial rituals of pre-industrial societies, according to a recent paper. 

The anti-wheat movement is a popular health fad in America and critics of that staple now have a new weapon in their culture war - ditching it makes people more cooperative. And they explain Genghis Khan and Mao.

Defenders of wheat have their own ammunition - rice leads to despotism and communism. Cultural psychologists writing in Science claim that they can explain psychological differences between the people of northern and southern China mirror and also the differences between community-oriented East Asia and the more individualistic Western world - southern China has grown rice for thousands of years, whereas the north has grown wheat.

It's common to perceive Neanderthals as more big-headed primitives and Cro-Magnon as more like us, but we were all primitive cavemen. It takes a biologist to really know the difference.

So if you think Neanderthals were stupid and primitive, it's time to think again.  

Would you sacrifice one person to save five?

Psychologists say those moral choices could depend on whether you are using a foreign language or your native tongue.

The new paper from the University of Chicago and Pompeu Fabra University in Barcelona finds that people using a foreign language take a relatively utilitarian approach to moral dilemmas, making decisions based on assessments of what's best for the common good. That pattern holds even when the utilitarian choice would produce an emotionally difficult outcome, such as sacrificing one life so others could live. 

Scholars say they have created a breakthrough on understanding the demographic history of Stone-Age humans.

A genomic analysis of eleven Stone-Age human remains from Scandinavia revealed that expanding Stone-age farmers assimilated local hunter-gatherers and that the hunter-gatherers were historically in lower numbers than the farmers. 

Dr. Bruna Bezerra from the University of Bristol and colleagues have captured video of a wild male marmoset embracing and caring for his dying partner after she accidentally fell from a tree in the Atlantic Forest in the Northeast of Brazil, the first time that compassionate care-taking behavior towards a dying adult group member has been observed in monkeys.

Previously, such behavior was believed to be unique to humans and chimpanzees.
