The whole topic of genes and genetic engineering is fascinating! Genetic engineering is changing medicine, agriculture and even the legal system. If you would like to learn about genetic engineering and biotechnology - for example, if you would like to know how a scientist can "engineer" bacteria to produce something like human insulin - then the HSW article entitled How Cells Work will be incredibly interesting. After you read it, many of the genetic engineering stories you see in the news will make a LOT more sense!
If bigger is better, then some of us have the advantage when it comes to brainpower. Human brains (and noggins) don't all look the same. Does size really matter? And if it does, who comes out on top?
You like to think of yourself as an individual. But the truth is there's a huge microbial party going inside and outside your body right now. And the folks from the Human Microbiome Project want to know what those microbes are up to.
