Not all wedded bliss: Marital stress linked to depression

Posted: 25 Apr 2014 07:46 AM PDT

Marital stress may make people more vulnerable to depression, according to a recent study. The long-term study shows that people who experience chronic marital stress are less able to savor positive experiences, a hallmark of depression. They are also more likely to report other depressive symptoms. Married people are, in general, happier and healthier than single people, according to numerous studies. But marriage can also be one of the most significant sources of long-lasting social stress.

Climate change: Don't wait until you can feel it

Posted: 25 Apr 2014 06:36 AM PDT

Despite overwhelming scientific evidence for the impending dangers of human-made climate change, policy decisions leading to substantial emissions reduction have been slow. New research shows that even as extreme weather events influence those who experience them to support policy to address climate change, waiting for the majority of people to live through such conditions firsthand could delay meaningful action by decades.

Couples need just one conversation to decide not to have children

Posted: 25 Apr 2014 04:52 AM PDT

Many couples agree not to have children after only one discussion, and sometimes none at all. "Not having children is obviously a very important decision, and what was interesting from the research was the negligible amount of discussion that couples engaged in -- many are agreeing not to have children in one conversation, or in an unspoken way," a researcher on the study noted. "One possible reason that couples did not need to talk about the issue much is that they could accurately sense their partner did not want children from their beliefs and lifestyle."

Increasing consumption of coffee associated with reduced risk of type 2 diabetes, study finds

Posted: 24 Apr 2014 04:05 PM PDT

Increasing coffee consumption by on average one and half cups per day over a four-year period reduces the risk of type 2 diabetes by 11 percent, research shows. Coffee and tea consumption has been associated with a lower type 2 diabetes risk but little is known about how changes in coffee and tea consumption influence subsequent type 2 diabetes risk, until now.

'Horsing around' reduces stress hormones in youth

Posted: 24 Apr 2014 02:05 PM PDT

New research reveals how youth who work with horses experience a substantial reduction in stress -- and the evidence lies in kids' saliva. "We were coming at this from a prevention perspective," said a developmental psychologist working on this study. "We are especially interested in optimizing healthy stress hormone production in young adolescents, because we know from other research that healthy stress hormone patterns may protect against the development of physical and mental health problems."

Ancient Maya and virtual worlds: Different perspectives on material meanings

Posted: 24 Apr 2014 12:18 PM PDT

The Mayan perspective on the material world has been explored in science, and begins to uncover parallels with today's online culture. The Maya believed that part of your identity could inhabit material objects. Maya might even name these objects, talk to them or take them to special events. They considered these items to be alive. The practice of sharing your identity with material possessions might seem unusual in a modern context. But is it that different from today's selfie-snapping, candy-crushing online culture, where social media profiles can be as important to a person's identity as his or her real-world interactions?

Risk of traffic accident injury depends on sex and age, Spanish study finds

Posted: 24 Apr 2014 08:30 AM PDT

Young men are more likely to injure themselves on the road or crossing a street than women, but among the elderly, females are more vulnerable. This is according to a study on injuries and citizen mobility. According to the researchers, the fact that the risk is greater in child pedestrians and young male drivers can be associated with their greater risk taking at the wheel and in the case of girls, when crossing the street, as well as the fact that they act recklessly more frequently, such as speeding and consuming psychoactive substances.

Marijuana use may increase heart complications in young, middle-aged adults

Posted: 23 Apr 2014 02:09 PM PDT

Marijuana use may result in heart-related complications in young and middle-aged adults. Nearly 2 percent of the health complications from marijuana use reported were cardiovascular related. A quarter of these complications resulted in death, according to a study. Surveillance of marijuana-related reports of cardiovascular disorders should continue and more research needs to look at how marijuana use might trigger cardiovascular events, researchers say.

Key to enjoying massive online photo files may be giving up some control

Posted: 23 Apr 2014 08:15 AM PDT

People who have massive online photo collections might actually enjoy their archives more by giving up a bit of control, research suggests. The 14-month study showed that people reflected more on past events and developed a renewed interest in their online photos when a device called Photobox would randomly print four or five of those photos at varying intervals each month.

Genetics risk, prenatal smoking may predict behavioral problems

Posted: 23 Apr 2014 07:21 AM PDT

An interaction between prenatal smoking and genetic risk factors has been discovered by researchers, which increases aggressive behavior in children, especially in girls. "The interesting issue is that not all children exposed to prenatal smoking will have behavioral problems," said the senior author on the study. "One possible explanation for this is that the effect of prenatal smoke exposure depends on the presence of 'triggering influence;' in this case, we investigated whether genetic risk factors might act as just such a trigger."

Psychological study of spite: 'Virtually ignored' by researchers

Posted: 23 Apr 2014 07:18 AM PDT

In spite of spite's large and small impacts, and the obvious power it can hold on the human psyche, it has been 'virtually ignored' by social, personality and clinical psychologists, researchers have said in a recent paper. They have attempted to remedy that oversight by measuring spitefulness with a test similar to those used for other personality traits.
