Distracted Much? What a Wandering Mind Says About Your Intelligence
Different brain patterns during the resting state may be associated with different cognitive abilities.
I’ve always been a daydreamer by nature and I remember a number of teachers pointing it out as I was growing up, calling on me randomly or telling me to get my head out of the clouds. When called on, I usually produced the right answer, which was even more frustrating to any anal retentive teacher with an axe to grind. Perhaps instead of chastising me, they should've encouraged such behavior. Turns out, a wandering mind may be a sign of greater intelligence. Daydreamers are also more creative. That’s according to a new study published in the journal Neuropsychologia.
If you get yelled at for daydreaming, tell whoever’s getting on your case that it only proves you have more brain capacity and whip this study, from the Georgia Institute of Technology. You're bound to get respect then. Tell them you can’t help it, too. According to Eric Schumacher, psychology professor and co-author, those with a wandering mind may find it hard to stop it from happening.
In this study, 112 volunteers allowed their brains to be scanned by an fMRI machine, while they were in a resting state. Participants were to focus on a central fixation point for a total of five minutes. Researchers wanted to know what kind of brain activity occurred while someone was in a resting state. Some studies suggest that different brain patterns when awake but at rest, could be associated with different cognitive abilities.

What Schumacher and colleagues found was that those subjects whose minds wandered scored higher on tests measuring intellect, executive function, and creativity. Participants also filled out a questionnaire to gauge how often their minds wander.
Meanwhile, the fMRI scans revealed that daydreamer’s brains were more efficient than those who tended to stay focused. Efficiency means a greater capacity to think, according to Schumacher. So the people carrying such brains may be more likely to notice their minds wandering while performing menial tasks.
"Our findings remind me of the absent-minded professor,” Schumacher said, “someone who's brilliant, but off in his or her own world, sometimes oblivious to their own surroundings." He added, "Or school children who are too intellectually advanced for their classes. While it may take five minutes for their friends to learn something new, they figure it out in a minute, then check out and start daydreaming."

He and colleagues say this will open up more research on daydreaming, what it means, and its effects on the dreamer. One shortcoming, the study didn’t prove a cause-and-effect relationship, merely a correlation between daydreaming and brain efficiency. Another problem is that the sample size was small.
Some other studies have found daydreaming may equate to lower scores on academic tests or in reading comprehension. Daydreamers may also be less apt at analyzing external events. But other studies have found those who often daydream come up with more creative solutions to problems.
So how do you know if you have a highly efficient brain? Consider how often you daydream during routine tasks. Do you wander off during conversations or presentations, only to come back without missing anything?
If so, huzzah! You may be among the select few, highly efficient thinkers out there. Allow me to welcome you among our ranks. And let us emit a resounding harrumph for all those anal retentive teachers of the past who tried to suppress our advanced cognitive capabilities. Harrumph! Harr-umph!

What can 3D printing do for medicine? The "sky is the limit," says Northwell Health researcher Dr. Todd Goldstein.
- Medical professionals are currently using 3D printers to create prosthetics and patient-specific organ models that doctors can use to prepare for surgery.
- Eventually, scientists hope to print patient-specific organs that can be transplanted safely into the human body.
- Northwell Health, New York State's largest health care provider, is pioneering 3D printing in medicine in three key ways.
Can dirt help us fight off stress? Groundbreaking new research shows how.
- New research identifies a bacterium that helps block anxiety.
- Scientists say this can lead to drugs for first responders and soldiers, preventing PTSD and other mental issues.
- The finding builds on the hygiene hypothesis, first proposed in 1989.
Are modern societies trying too hard to be clean, at the detriment to public health? Scientists discovered that a microorganism living in dirt can actually be good for us, potentially helping the body to fight off stress. Harnessing its powers can lead to a "stress vaccine".
Researchers at the University of Colorado Boulder found that the fatty 10(Z)-hexadecenoic acid from the soil-residing bacterium Mycobacterium vaccae aids immune cells in blocking pathways that increase inflammation and the ability to combat stress.
The study's senior author and Integrative Physiology Professor Christopher Lowry described this fat as "one of the main ingredients" in the "special sauce" that causes the beneficial effects of the bacterium.
The finding goes hand in hand with the "hygiene hypothesis," initially proposed in 1989 by the British scientist David Strachan. He maintained that our generally sterile modern world prevents children from being exposed to certain microorganisms, resulting in compromised immune systems and greater incidences of asthma and allergies.
Contemporary research fine-tuned the hypothesis, finding that not interacting with so-called "old friends" or helpful microbes in the soil and the environment, rather than the ones that cause illnesses, is what's detrimental. In particular, our mental health could be at stake.
"The idea is that as humans have moved away from farms and an agricultural or hunter-gatherer existence into cities, we have lost contact with organisms that served to regulate our immune system and suppress inappropriate inflammation," explained Lowry. "That has put us at higher risk for inflammatory disease and stress-related psychiatric disorders."

This is not the first study on the subject from Lowry, who published previous work showing the connection between being exposed to healthy bacteria and mental health. He found that being raised with animals and dust in a rural environment helps children develop more stress-proof immune systems. Such kids were also likely to be less at risk for mental illnesses than people living in the city without pets.
Lowry's other work also pointed out that the soil-based bacterium Mycobacterium vaccae acts like an antidepressant when injected into rodents. It alters their behavior and has lasting anti-inflammatory effects on the brain, according to the press release from the University of Colorado Boulder. Prolonged inflammation can lead to such stress-related disorders as PTSD.
The new study from Lowry and his team identified why that worked by pinpointing the specific fatty acid responsible. They showed that when the 10(Z)-hexadecenoic acid gets into cells, it works like a lock, attaching itself to the peroxisome proliferator-activated receptor (PPAR). This allows it to block a number of key pathways responsible for inflammation. Pre-treating the cells with the acid (or lipid) made them withstand inflammation better.
Lowry thinks this understanding can lead to creating a "stress vaccine" that can be given to people in high-stress jobs, like first responders or soldiers. The vaccine can prevent the psychological effects of stress.
What's more, this friendly bacterium is not the only potentially helpful organism we can find in soil.
"This is just one strain of one species of one type of bacterium that is found in the soil but there are millions of other strains in soils," said Lowry. "We are just beginning to see the tip of the iceberg in terms of identifying the mechanisms through which they have evolved to keep us healthy. It should inspire awe in all of us."

We were gaining three IQ points per decade for many, many years. Now, that's going backward. Could this explain some of our choices lately?
There's a new study out of Norway that indicates our—well, technically, their—IQs are shrinking, to the tune of about seven IQ points per generation.
