Ever wonder where all that food your teenager devoured was going? Not only does the food go into the teen's daily activities--running, doing homework, breathing and playing video games, but food converted to energy also fuels growth of new tissues--bones, vessels, cartilage, muscle.  In poorer areas of the world, part of the energy yielded by food might be deflected for the body's defense system in fighting disease. Children and teens in such conditions will not grow as tall or big as their healthy counterparts who were able to allocate more of their energy stores directly to growth.

In the spirit of Halloween, it seems most appropriate to share Annette Child's encounters with the afterlife.



Margaret Borwhat co-founded the Women's Cancer Advocacy Network (WCAN) in 1997 while waging her own fight against the disease. This resolute woman was a powerhouse to the end and though she peacefully succumbed in body in 2006, her spirit took up the banner for a new dimension of the crusade. She wants us to know that this life is not all there is. And, much to his chagrin, Margaret left her skeptical husband, Don, with an undeniable "foo foo" experience that was the first of endless pranks to prove to him there is an afterlife.

I have recently criticized British geneticist Steve Jones for his claim that modern human societies are no longer subject to natural selection. My arguments were based on basic principles of evolution and population genetics. Now a new study shows that Jones is wrong on the basis of the available empirical evidence and, ironically, that evidence comes from research on the British population!

Vampires, Mummies, Ghosts, Zombies - we have it all today.   We even have costumes.   Why?  Halloween, like everything else great in life, has a science aspect to it.

In 2006, Al Gore alleged that Hurricane Katrina had been caused, or at least made worse, by global warming.    Bill Gray, one of the foremost hurricane experts in the world, disagreed.    Who was right?   Weather, and especially hurricanes, are not among things that are easy to predict but global warming is certain to have an impact.   What impact is all depending on what you want to believe.

Don't start feeling too secure about the so-called McEliece encryption system - a candidate for the security of Internet traffic in the age of the quantum computer, the predicted superpowerful computer of the future.

Researchers at Eindhoven University of Technology (TU/e) in The Netherlands have managed to crack it.

Scientists know how to have a good time. Just ask Yahoo Serious about when he played Young Einstein. That guy really knew how to par-tay! To see for yourself this Halloween, host your very own Mad Scientist Halloween Party. Check out these ideas to really get your party started. You'll be amazed at how easily you can transform your digs into a Spooky Laboratory!

Every year at about this time, I start to wonder what I am going to be for Halloween. Despite my best efforts, it usually takes up a large amount of my brainpower until a few days before Halloween, and then I am so excited about my impending costume debut, I parade it around the house, and end up feeling like an idiot. It’s okay, you can laugh.

Halloween is just one of those holidays. It allows people to express themselves in ways that are simply unacceptable the other 364 days of the year. For one day (or weekend for the adults) you may dress as anything or anyone you can imagine, from the most classic of Halloween costumes, to the latest in vogue celebrity. So if either you want to dress as a devil or Sarah Palin (or both), here are some ideas to get those creative juices flowing so you can fulfill your heart's desire on Halloween.

Halloween is a holiday with lots of creepy wildlife associated with it, but are they really so creepy? From toads to bats to owls, the National Wildlife Federation shares the facts about these animals and what they are up to at this time of year, which might dispel a few myths.

Bats - are they out for my blood?

It may begin as a feeling of unease that overtakes you as you cautiously make your way inside a long-abandoned house.  The air is thick; musty and stale.  Yet somehow it is laced with the underlying scent  of a burning fire… even though the cold crumbling fireplace hosted its last fire long ago.
 
As your eyes adjust, you begin to notice the stillness. There is absolutely no noise.  In fact, the silence is so oppressive, it presses in on your eardrums like the weight of an ocean… seeking to snuff out the sound of anything that should trespass upon it.  You get the distinct feeling it would like to quiet even the uneven sound of your shallow breaths… and then move on to silence the thump of your increasingly racing heartbeat.
