The possibility that autism is more common in offspring of older parents has generated considerable interest. To investigate the theory, a study using data from 10 US study sites participating in the Centers for Disease Control and Prevention's Autism and Developmental Disabilities Monitoring Network, was developed to examine the relation between parental age at delivery and the prevalence of autism spectrum disorder (ASD). Confirmation of such an association has important public health implications in light of increasing trends in recent decades for couples to delay having children.
I'm a mother of three, with an aeronautical engineering degree. Although it's been a while since I've done any aircraft design, there are surprising applications of my scientific background in my current role as a full-time mom. So whenever possibl…
Christmas trees are appearing in homes throughout the country and families prepare for the holiday season. But in this age when we are all asked to be aware of the impact we are having on the environment, is the right choice to purchase an artificial tree and use it year after year, or go in search of the perfect living tree to be the centerpiece of our holiday decorating?
The answer may surprise you.
So the kids fell asleep late last night after finally crashing from their Halloween sugar high. There are smashed pumpkins out on the street, toilet paper in the trees, and still 3 to 5 pounds of candy remaining per child. The pumpkins and toilet paper can be cleaned up… but what do you do with all that candy? You can’t possibly eat it all, right?
Well go ahead and give it a your best shot. But a week from now when it’s still around and you can’t stand the sight of the stuff, you’ll be happy to know that science once again has a solution.
If you can get away from the city lights this weekend, conditions are perfect to view the annual Perseid Meteor shower that is expected to peak Sunday night and into Monday morning, August 12th and 13th. Because we will be experiencing a new moon this weekend, there will be no moonlight to interfere with the spectacular show as meteors streak across the sky.
The answer is, of course... it depends. But with gas prices as high as they are these days, it’s good to know when it’s worthwhile to drive a few miles to save five cents a gallon, or when it’s just better to fill up at the station around the corner.
To determine where you should top off your tank, it’s just a matter of running the numbers.
On Saturday, 07/07/07, the New 7 Wonders of the World were announced. The announcement got me thinking about other everyday “wonders” that I rely on, and am in constant appreciation of, as a mom. Those little things that have become so ingrained in my everyday routine, that I barely notice them anymore – but that would make my day so much more difficult if I didn’t have. These are the items that make my job as a mom… heck, I’ll just say it – Wonder-ful!
First let's take a look at the Newest 7 Wonders of the World. They were selected by a global poll, where 100 million votes were cast via the Internet and cell-phone text messages.
You can’t watch the news, turn on the radio, or open a newspaper these days without hearing about global warming. It seems our future is looking rather warmish, and many of our modern conveniences may be to blame.
I’m not disputing the fact, but at the same time I’ve never had it explained to me precisely and quantitatively how many of the choices I make each day are contributing to global warming. I mean, I understand the link between driving my car and carbon emissions. The family minivan spews carbon dioxide for goodness sake, so I clearly understand how running my daily errands in a gasoline-powered car can contribute to the problem.
If you have bad kids, it may not be your fault.
Well, it could still be your fault, because it's biology and genetics is part of biology, but you can't control genetics. At least you then you wouldn't have to feel guilty about being a lousy parent.
Either way there's a real effort on to blame everything except the actual delinquent kids and a new study in Psychological Science advances that cause. Rutgers University psychologist Daniel Hart and colleagues write that they can use a a Skin Conductance Response (SCR) test, along with some family history, to predict delinquency.
10. Chocolate contains tryptophan, a chemical in the brain that is used to produce the neurotransmitter, serotonin. High levels of serotonin stimulate the secretion of endorphins, and produce feelings of elation. Serotonin is found in the antidepressant Prozac, and the designer drug “ecstasy” produces its effects by increasing serotonin levels in the brain. So… antidepressants, illegal drugs, or a Hershey’s bar. You pick.
How is it that I didn’t hear about this sooner? It appears that this year Daylight Savings Time is starting earlier, and ending later, than its traditional first-of-April to end-of-October run. It will begin this year on March 11th, and end on November 4th – a bonus four weeks for no additional cost.
Daniel Bernoulli was never a mom. He might have been a father, a fantastic one at that, I don't actually know. But that's not why I know of him. Bernoulli was a mathematician and scientist from the 1700's, and I was introduced to him during my fluid dynamics class in college.
