Four Loko was a fruit-flavored, caffeinated, alcoholic drink that was invented by three Ohio State University students in 2005. Following a series of accidents, injuries, and deaths on college campuses and elsewhere, most of the discussion about the harmful effects of the drink centered on the combination of caffeine and alcohol. “Some have claimed,” writes McMaster University psychologist Shepard Siegel in the latest issue of Perspectives on Psychological Science, “that the st........

How does an ostrich sleep? Almost imperceptibly, it seems. Even though an ostrich might be sound asleep, it can look wide awake or, at most, a little drowsy. John Lesku from the Max Planck Institute of Ornithology discovered this by fitting six ostrichers with “Neurologgers”, electrode-laden helmets that measures their temperature, brain activity, eye movements and neck muscle contractions.
The video above shows three of the birds cycling through two different types of sleep. The first is c........ Read more »
As developed nations around the world have attempted to deinstitutionalize mental health care, the number of beds available for inpatient treatment has declined. A recent survey of mental health care reported that the decrease in bed space leads to more involuntary admissions for mental health care. Wealthy, developed nations throughout the world, including the United [...]... Read more »

I like to imagine that actin and microtubules duked it out one day over which was more important. Actin let microtubules have the mitotic spindle, as long as actin could have the leading edge. So, imagine how ticked off microtubules were to learn that actin was discovered a few years ago to play an important role in Golgi organization, a task long-associated with microtubules. Zoinks!

We know that psychologically detaching from work is important, leading to less fatigue, more positive working-week experiences, and higher overall life satisfaction. How you fill your leisure time has a big impact on psychological detachment - for instance, we've reported on the beneficial effects of volunteering on detachment. A recent study confirms what many suspect – it's harder to switch off when technology keeps you plugged in.
In their study, YoungAh Park, Charlotte Fritz and Steve Je........ Read more »

"Fat Children Eat Less Than Their Thinner Peers". That's the tweet Linda Bacon from HAES fame sent out to her followers at 9:55am yesterday morning.
It certainly fits the HAES narrative that the world's completely backwards in regard to anything and everything weight related.
Sadly it also continues Linda's confusing practice of tweeting bad data.
Linda's HAES platform, whether you agree or disagree with it, rests on the shoulders of her critical analysis of the medical literature on obesit........ Read more »

Multiple sclerosis is an autoimmune disease of the central nervous system that causes neurological disability in young adults. Several environmental and genetic factors have been linked to the disease, but the precise mechanisms involved, and whether neurological damage precedes inflammation or vice versa, remain unclear.

You may have seen, earlier this month, one of several news reports about how belief in God is great for reducing worries (e.g. here). Well no, that's not really what the study found - the study is actually a bit more precisely focussed than that and a bit more interesting for it.
The researchers, lead by David Rosmarin at Harvard Medical School, were interested in the idea that the Middle-Eastern monotheisms place a great deal of focus on trusting God. Yet many believers don't trust their........ Read more »

Even animals without hands can display handedness--or, at least, a preference to do things with one side of the body rather than the other. Animals ranging from primates to birds to invertebrates have been shown to favor their left or right side. Fish might reveal that preference by choosing to swim right, for example, when avoiding a predator. Don't get too charmed by the idea of left-handed and right-handed fish, though: In a warming world, they may disappear.A new study by researchers in Ital........ Read more »

Growing up, I didn’t think anything of the fact that when I listened to music, I saw patterns of colors in my mind. I had no reason to question it, and nothing about it seemed too noteworthy. Sad Backstreet Boys songs meant swirling purples and blues and happy Backstreet Boys songs meant orange and yellow starbursts. It wasn’t until college that I became aware that the word for my experiences was synesthesia, and that I had pretty much stopped experiencing it.... Read more »

The human immune system is a large and complex beast, but in general it has two roles. Firstly, to prevent an infection from causing any harm and secondly to protect the body against a repeat attack. For many diseases protection against reinfection happens very efficiently, and this is the principle on which vaccines are based. By exposing your body to a non-harmful sample of the disease your immune system can built up resistance. For cytomegalovirus however the immune system seems mysteriously ........ Read more »
