Women and Men Organize Social Networks Differently
by Lizabetth Dijkstra in United Academics
Although we are not always aware of it in our daily communication, our interactive behaviour gives rise to complex social behaviouristic patterns. These complex forms of interaction, also named multiplex networks, like communication, trade networks or friendship, form the backbone structure of human culture.... Read more »

New strain could be available in a few years.

Grapefruits, albeit sour, are nutritious and can be delicious. But they’ve also been known to interfere with many medications, and even some dietary supplements. So, many doctors try to steer some patients away from eating grapefruit.... Read more »

Do you suffer from the IKEA Effect?
by Mark Fonseca Rendeiro in United Academics
If you are reading things from home or from the office, chances are there is something from Ikea in the room. Over the past decade, the affordable and semi-clever designs from the Swedish furniture juggernaut have become one of those recognizable symbols regardless of where in the world you live. And one aspect that is true about most Ikea stuff, is that you probably built it yourself. And if you built it yourself, there is a certain satisfaction that comes with having used that strange little tool and fit “wood screw A” into “panel 3″, a feeling that is know in the world of psychology as the “Ikea Effect”....

The Foods that Play a Factor in Deep Sleep
by Zach Urbina in United Academics
If the quest for the perfect night’s sleep remains one of your goals, you might need to start at the grocery store.
A recently published study out of the University of Pennsylvania isolated a few key nutrients and total caloric intake as contributing factors for length and duration of sleep. They also looked at the role that overall diet, demographics, socioeconomics, physical activity, and obesity, to rule out other potential causes.... Read more »

Exposure to Pesticides Increases Risk of Diabetes
by Zachery Urbina in United Academics
North Americans and Europeans have ballooned up to noticeably fatter proportions in recent decades, and new research originating from the University of Granada has revealed a direct connection between exposure to pesticides in food, air, and water & incidence of adult-onset type 2 diabetes. The relationship was found to exist without respect to age, gender or body mass index, according to data in the study.... Read more »

Hospitalizations from Energy Drinks Continue to Rise

Who’s Smarter, the Dog Or the Cat?
by Katja Keuchenius in United Academics
Cats may seem more intelligent than dogs because they behave quite autonomous compared to dogs that are always waiting for commands. But the opposite might actually be true: social behavior seems to require bigger brains.
It’s always hard to compare the intelligence of cats and dogs. Some studies point out that dogs can learn hundreds of words, other than cats. And they understand human gestures, like pointing, which even chimpanzees don’t seem to comprehend.... Read more »

VIDEO: Stunning Footage of a Thought Being Formed
by Zach Urbina in United Academics
Shown at three times natural speed, this video the first ever thought being documented while it was being formed. The zebrafish is an ideal candidate for this advanced area of study as its skin remains transparent during early development. The brilliant flash in this particular moment coincided with the passing of a nearby paramecium, and correlated with hunting behavior in the zebrafish. To put it bluntly, the fish was thinking; dinner. Truly a remarkable leap forward in field of neuroscience... Read more »

Don’t Panic If You Didn’t Get 8 Hours of Sleep
by Zach Urbina in United Academics
Feeling like you’re falling behind on sleep lately? Don’t worry too much. Recently published research from the University of Sydney demonstrated that sleep duration shifts periodically over the course of the month. These shifts occur independent of lifestyle, social, and/or environmental influences.
‘Sleep requirements vary in a cyclical fashion and between individuals. If you incur a sleep debt, your body will signal a need to catch up on extra sleep,’ said Dr. Chin Moi Chow, principal investigator of the article published this month in Nature and Science of Sleep.... Read more »

Flirting Most Effective on a Sunny Day
by Carian Thus in United Academics
Studies have shown that sunshine activates positive emotions and good mood, which in turn can facilitate social relationships. For example, we are more likely to help others on sunny days. Now, a French researcher explored whether positive weather conditions also benefit courtship behavior.
So how do you test this? Simple: ask attractive, 20-year-old men to approach young women (about 500) walking alone in a shopping mall on either cloudy or sunny days (controlling for temperature). Their goal? Scoring phone numbers.... Read more »

Happier Children Earn Higher Wages in Adulthood
by Jalees Rehman in United Academics
There is quite a bit of debate about the scientific validity of the proverb “money can’t buy happiness”, because studies on this topic have resulted in discordant results. Some studies support the idea that richer people are happier on average than poor people, but there are also reports that while the median income in the US has grown in recent decades, average happiness among Americans has hardly changed....
