Well?

Not highlighted, out of principle!

Can You Become a Creature of New Habits? by Janet Rae-Dupree (NYT)

Apparently,

... brain researchers have discovered that when we consciously develop new habits, we create parallel synaptic paths, and even entirely new brain cells, that can jump our trains of thought onto new, innovative tracks.


Definitely interesting, not to mention helpful if you're trying to get over old habits (or form new ones). Read more here, or highlights below.

But don’t bother trying to kill off old habits; once those ruts of procedure are worn into the hippocampus, they’re there to stay. Instead, the new habits we deliberately ingrain into ourselves create parallel pathways that can bypass those old roads.


Good to know!

Researchers in the late 1960s discovered that humans are born with the capacity to approach challenges in four primary ways: analytically, procedurally, relationally (or collaboratively) and innovatively. At puberty, however, the brain shuts down half of that capacity, preserving only those modes of thought that have seemed most valuable during the first decade or so of life.


If you’re an analytical or procedural thinker, you learn in different ways than someone who is inherently innovative or collaborative. Figure out what has worked for you when you’ve learned in the past, and you can draw your own map for developing additional skills and behaviors for the future.


"If you have a pathway to learning, use it because that’s going to be easier than creating an entirely new pathway in your brain.”


We tend to believe that those who think the way we do are smarter than those who don’t. ... If seniority and promotion are based on similarity to those at the top, chances are strong that the company lacks intellectual diversity.

11 Odd but Simple Ways to Improve Your Health

Unconventional ways to improve your health

I'm down with all but 6 and 8 (they seem to product oriented and I know little about them); on the fence about 2 (only cuz I've never heard of that before).

A lot of it seemed focused on helping us detoxify gunk that builds up in our bodies.

i really need to fix my posture. again.

"South Asians face increased heart risk"

Damn. More motivation to work out?

The same yellow fat that hugs Ashok's heart also surrounds his other organs. This abdominal, or visceral fat, is much more active – and dangerous – than the fat found under your skin. It acts like a furnace to produce toxic fumes in the body, decreasing insulin sensitivity, reducing good cholesterol levels and raising blood pressure, all of which are risk factors for heart disease.

Sonia Anand, an associate professor of medicine at McMaster University and an international expert on the links between ethnicity and heart disease and diabetes, says South Asians are more likely to get visceral fat than any other ethnic group, even if they eat and exercise the same. People of South Asian descent are also more apt to have the same array of risk factors for heart disease as Caucasians, but at about 45 pounds lighter, she says.

Medicine's Cutting Edge: Re-Growing Organs

(CBS) Imagine re-growing a severed fingertip, or creating an organ in the lab that can be transplanted into a patient without risk of rejection. It sounds like science fiction, but it's not. It's the burgeoning field of regenerative medicine, in which scientists are learning to harness the body's own power to regenerate itself, with astonishing results. Correspondent Wyatt Andrews brings you to the scientific frontier.


Craziness. And depressing to see so many of the injured Army Veterans.

"The Secret to Raising Smart Kids" By Carol S. Dweck

Really interesting article from Scientific American Mind which talks about how our mindset in regards to our own intelligence (is it innate or learned?) can have a tremendous impact on our ability to learn and success in almost every aspect of our life. Brings up quite a few experiments involving children and college students in regards to their schooling, but also briefly discusses the effect a person's mindset can have on their careers or personal relationships. Basically: don't think you're smart, but realize that everyone has the ability to become it; our mistakes help us grow, so long as we learn from them.

Highlights:

Our society worships talent, and many people assume that possessing superior intelligence or ability—along with confidence in that ability—is a recipe for success. In fact, however, more than 30 years of scientific investigation suggests that an overemphasis on intellect or talent leaves people vulnerable to failure, fearful of challenges and unwilling to remedy their shortcomings.


Praising children’s innate abilities, as Jonathan’s parents did, reinforces this mind-set, which can also prevent young athletes or people in the workforce and even marriages from living up to their potential. On the other hand, our studies show that teaching people to have a “growth mind-set,” which encourages a focus on effort rather than on intelligence or talent, helps make them into high achievers in school and in life.


Subsequent studies revealed that the most persistent students do not ruminate about their own failure much at all but instead think of mistakes as problems to be solved. At the University of Illinois in the 1970s I, along with my then graduate student Carol Diener, asked 60 fifth graders to think out loud while they solved very difficult pattern-recognition problems. Some students reacted defensively to mistakes, denigrating their skills with comments such as “I never did have a good rememory,” and their problem-solving strategies deteriorated.

Others, meanwhile, focused on fixing errors and honing their skills. One advised himself: “I should slow down and try to figure this out.” Two schoolchildren were particularly inspiring. One, in the wake of difficulty, pulled up his chair, rubbed his hands together, smacked his lips and said, “I love a challenge!” The other, also confronting the hard problems, looked up at the experimenter and approvingly declared, “I was hoping this would be informative!” Predictably, the students with this attitude outperformed their cohorts in these studies.


The helpless ones believe that intelligence is a fixed trait: you have only a certain amount, and that’s that. I call this a “fixed mind-set.” Mistakes crack their self-confidence because they attribute errors to a lack of ability, which they feel powerless to change.


The mastery-oriented children, on the other hand, think intelligence is malleable and can be developed through education and hard work. They want to learn above all else. After all, if you believe that you can expand your intellectual skills, you want to do just that. Because slipups stem from a lack of effort, not ability, they can be remedied by more effort. Challenges are energizing rather than intimidating; they offer opportunities to learn. Students with such a growth mind-set, we predicted, were destined for greater academic success and were quite likely to outperform their counterparts.


At the start of junior high, the math achievement test scores of the students with a growth mind-set were comparable to those of students who displayed a fixed mind-set. But as the work became more difficult, the students with a growth mind-set showed greater persistence. As a result, their math grades overtook those of the other students by the end of the first semester—and the gap between the two groups continued to widen during the two years we followed them.


Mind-set can affect the quality and longevity of personal relationships as well, through people’s willingness—or unwillingness—to deal with difficulties. Those with a fixed mind-set are less likely than those with a growth mind-set to broach problems in their relationships and to try to solve them, according to a 2006 study I conducted with psychologist Lara Kammrath of Wilfrid Laurier University in Ontario. After all, if you think that human personality traits are more or less fixed, relationship repair seems largely futile. Individuals who believe people can change and grow, however, are more confident that confronting concerns in their relationships will lead to resolutions.


How do we transmit a growth mind-set to our children? One way is by telling stories about achievements that result from hard work. For instance, talking about math geniuses who were more or less born that way puts students in a fixed mind-set, but descriptions of great mathematicians who fell in love with math and developed amazing skills engenders a growth mind-set, our studies have shown. People also communicate mind-sets through praise. Although many, if not most, parents believe that they should build up a child by telling him or her how brilliant and talented he or she is, our research suggests that this is misguided.


In the growth mind-set classes, students read and discussed an article entitled “You Can Grow Your Brain.” They were taught that the brain is like a muscle that gets stronger with use and that learning prompts neurons in the brain to grow new connections. From such instruction, many students began to see themselves as agents of their own brain development. Students who had been disruptive or bored sat still and took note. One particularly unruly boy looked up during the discussion and said, “You mean I don’t have to be dumb?”


We have now encapsulated such instruction in an interactive computer program called “Brain­ology,” which should be more widely available by mid-2008. Its six modules teach students about the brain—what it does and how to make it work better. In a virtual brain lab, users can click on brain regions to determine their functions or on nerve endings to see how connections form when people learn. Users can also advise virtual students with problems as a way of practicing how to handle schoolwork difficulties; additionally, users keep an online journal of their study practices.

What Makes Us Moral By Jeffrey Kluger (Time Magazine)

What Makes Us Moral

Brief highlight of various experiments dealing with morality and empathy and their connections to activity in different sections of the brain. Interesting, if for no other reason than to get a superficial idea about the results experiments that are being done.

Highlights:

The deepest foundation on which morality is built is the phenomenon of empathy, the understanding that what hurts me would feel the same way to you. And human ego notwithstanding, it's a quality other species share.


While it's impossible to directly measure empathy in animals, in humans it's another matter. Hauser cites a study in which spouses or unmarried couples underwent functional magnetic resonance imaging (fMRI) as they were subjected to mild pain. They were warned before each time the painful stimulus was administered, and their brains lit up in a characteristic way signaling mild dread. They were then told that they were not going to feel the discomfort but that their partner was. Even when they couldn't see their partner, the brains of the subjects lit up precisely as if they were about to experience the pain themselves. "This is very much an 'I feel your pain' experience," says Hauser.


This made me sad:

Schulman, the psychologist and author, works with delinquent adolescents at a residential treatment center in Yonkers, New York, and was struck one day by the outrage that swept through the place when the residents learned that three of the boys had mugged an elderly woman. "I wouldn't mug an old lady. That could be my grandmother," one said. Schulman asked whom it would be O.K. to mug. The boy answered, "A Chinese delivery guy." Explains Schulman: "The old lady is someone they could empathize with. The Chinese delivery guy is alien, literally and figuratively, to them."
