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 »

What do you do when you’re single and want to have sex? There’s the option to hookup with strangers. But you can also stay in your “comfort zone” and have sex with someone you already hang out with.... Read more »

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........ Read more »

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 »

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 »

Historical accounts tell us that the stimulating power of caffeine was first noticed in the 9th century by an Ethiopian goatherd who found his flock wildly excited after consuming coffee berries. Whoever he was, a substantial portion from the efforts of human progress since remains indebted to that discovery.... Read more »

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 »

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 »

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. Chi........ Read more »

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 goa........ Read more »

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....

A new study that analyzes the costs of risky sex has found that the sexual revolution actually began during the 1950s, a decade earlier than popular culture concedes.
Emory University economics researcher Andrew Francis analyzed data from US health agencies from the 1930s to the 1970s and found that between 1947 and 1957, the syphilis death rate dropped by 75 percent, while the syphilis rate of incidence dropped a staggering 95 percent.... Read more »

Sex, it turns out, is a risky affair. Besides infidelity, sexually transmitted diseases or pregnancy, it can also perpetuate harmful genes. Also, compared to asexual reproduction, it’s very inefficient—bacteria, strawberries and even some amphibians don’t have to look for a mate. So, why have sex—sexual reproduction, that is?...

As you read this very post, you may be sitting at home, one of the small but growing percentage of individuals around the world who work from home. Or perhaps you some work from home and other days you go to the office. Whatever the arrangement, is it a well known trend with a mix of benefits and long term questions, as more businesses and workers invest in the concept of what is sometimes called telework. Frequently updated research looks into aspects such as cost/benefit and productivity. ........ Read more »
