Smart Jocks: Sport Helps Kids Classroom Performance
When kids exercise, they boost brainpower as well as brawn
By Steve Ayan | September 9, 2010
5Despite frequent reports that regular exercise benefits the adult brain, when it comes to schoolchildren, the concept of the dumb jock persists. The star quarterback stands in stark contrast to the math-team champion. After all, the two types require seemingly disparate talents: physical prowess versus intellect. Letting kids run around or throw a ball seems, at best, tangential to the real work of learning and, at worst, a distraction from 1it.
Parents, teachers and education policy makers have pitted athletics against academics even as they trumpet exercise as an antidote to obesity and poor health. From preschool onward, teachers encourage children to sit still 7rather than scamper. Many schools have cut back on physical education to make room for the three R's. 4And when student scores on standardized tests become of primary importance to parents, politicians or other stakeholders in the education system, educators may feel pressured to direct students toward academic pursuits and away from athletic ones.
In Brief
Students who are fit — based on their high aerobic capacity and low body fat — also tend to perform well in school and on standardized tests.
6In addition to regular exercise, brief periods of movement such as jumping or stretching 2can help improve children's concentration.
Exercise 3may turbocharge the brain by raising levels of neuronal growth factors, which foster the formation of new connections between brain cells.

2012’s Second Sun
Earth is believed to be getting a second sun burning in the sky near the end of 2012, as the second biggest star in the universe, Betelgeuse, is dying, which will lead to “multiple days of constant daylight.”
Many ancient cultures 4have speculated about the appearance of a second sun and this event appears to 1tie in very closely with the December 21 2012 predictions.
Betelgeuse is the second 2biggest star in the universe and the eighth 3brightest in the night sky, Scientists 5have determined that the star is losing mass at a rapid rate, which indicates it will go supernova very soon.
The light emitted from this exploding star will be so bright that it will appear for a few weeks at the end of 2012 as a second sun in the sky. There may be little if no period of darkness or night according to senior lecturer of physics at the University of Southern Queensland, Brad Carter.
Earth will experience “brightness for a brief period of time for a couple of weeks and then over the coming months it begins to fade and then eventually it will be very hard to see at all,” explained the Australian scientist Brad Carter to news.com.au.
Scientist 6have known about this dying star which is 640 light years away from Earth, since 2005. It is believed that as Betelgeuse goes supernova it will not be harmful to Earth. “There will be neutrinos emitted during the supernova process, said University of Minnesota physics professor Priscilla Cushman, but neutrinos, even lots and lots of them, are only weakly interacting, so they won't affect life on earth,” but that is only speculation at this point.
The fact is, we as human beings have never experienced anything like this before so close to our home planet, and to be honest, we just don’t know for sure what this event could bring.

Go Easy on Yourself
By Stuart Bradford
Do you treat yourself as well as you treat your friends and family?
That simple question is the basis for a new area of psychological research called self-compassion — how ________ (I) people view themselves. People who find it ________ (II) to be supportive and understanding to others often score ________ (III) low on self-compassion tests. They get ________ (IV) with themselves for perceived failures like being overweight or not exercising.
ANXIOUS
The research suggests that accepting our imperfections may be the first step toward better health. People who score high on tests of self-compassion have less depression and anxiety, and tend to be happier and more optimistic. Preliminary data suggest that self-compassion can even influence how much we eat and may help some people lose weight.
This idea does contrast with the advice of many doctors and self-help books, which suggest that willpower and self-discipline are the keys to better health. But Kristin Neff, a pioneer in the field, says self-compassion is not to be confused with self-indulgence or lower standards.
“I found in my research that the biggest reason people aren’t more self-compassionate is that they are afraid they’ll become self-indulgent,” said Dr. Neff, an associate professor of human development at the University of Texas at Austin. “They believe self-criticism is what keeps them in line. Most people have gotten it wrong because our culture says being hard on yourself is the way to be.”
