so is there a genetic reason you’re a smarty pants?

Growing up, when you brought home an A on a test, did your parents ever argue over who’s side of the family “the smarts” came from?  I can recall complete reconstructions of the family tree based on what subjects my sister and I were excelling in.

In reality, the grades probably had more to do with good study habits and a certain pride in my work, but new research indicates that there may be more of a genetic component than previously realized.  In addition to diet, as we learned in my last post, recent work from Dr. Paul Thompson’s team reveals that genetic variations can have measurable impacts on learning and intelligence.  I came across his work thanks to a great piece written by Moheb Costandi at ScienceNOW.

keep your muscles big and strong…while doing nothing

What a beast Popeye was.  No time in the gym, no real effort whatsoever.  Just pop a can of leafy greens and lookout.  Maybe you’re of his ilk, but personally, I have to put a little work towards attempting a stunning physique.

Perhaps that won’t be the case in the future, however.  Yet again, I present another bit of research in the vein of good ole’ exercise.  Dr. Andrew R. Judge’s team at the University of Florida has recently published their findings on the regulation of muscle mass in the Journal of the Federation of American Societies for Experimental Biology.

working out accomplishes more than you ever imagined

A good friend of mine pointed me to what’s turned out to be a very successful strength training program about a year back.  However, when I first checked out the website, this image was the first thing I saw.  I kid you not.  I don’t want to work for the circus, maybe just get in better shape.  Luckily, those results apparently aren’t typical.  Or I’m not doing it right.  Who knows.

In any case, building up muscles or endurance isn’t the only thing that comes from exercise.  As we learn from an article published recently in Cell Metabolism, it stimulates changes all the way down to our DNA. Continue reading →

maybe all we need in the fight against cancer is a little extra…

Dave Koechner in Waiting

If you’ve never seen the movie “Waiting,” you’ve done a true disservice to yourself.   You’re missing out on the inner workings of a crappy chain restaurant, a horribly hilarious coworker game, and, most importantly, I don’t know how you’ve made it until now without Dave Koechner’s sage advice, “Remember, the difference between ordinary and extraordinary…is that little extra.”

Seems like that little extra is just as important in other avenues in life, as evidenced by a paper published recently in Cell Metabolism by Dr. Manuel Serrano’s group.  His team in Madrid has discovered that mice with an extra copy of a cancer suppressing gene live longer, healthier lives with a lower cancer incidence.
