Netbook use is on the rise everywhere--including your local library! Find outwhat you need to know about these tiny, affordable computers before you purchase.
This year marks the two hundredth anniversary of the birth of Charles Darwin and the hundred and fiftieth anniversary of his ground-breaking book, “On the Origin of Species.” Kathryn Lasky’s new illustrated biography, “One Beetle Too Many,” makes an appealing introduction for nine- to twelve-year-olds to the man and his “idea that scared the world.”
It has been fascinating to observe the rising adoption rates of netbooks. Think of netbooks as filling the technological niche between smartphones (such as the Blackberry and the iPhone) and full-sized laptops: they are compact, light-weight, and inexpensive computers for the price-conscious mobile user.

Bulldozers replace tractors as common sights along the road. It's the pavement, buildings, and the inevitable traffic that comes along with both that guarantees a rise in air pollution. The future looks hazy from here—as well as hot and humid.
Water, water everywhere…but is it safe to drink?
With bottled water costing well over a buck at the convenience store, budget-conscious folks have been switching to tap water. After all, the argument goes, tap water goes through filtration, too, and has the added benefit of fluoride. News stories blamed the rise in kids' cavities on a switch to bottled water. Surely it made more sense to stick with tap water. Now we find out that tap water and perhaps bottled water contain traces of prescription medications, causing people to reconsider their daily water source.
