Another League Under the Sea
A new generation of manned submersibles will soon open up 98 percent of the world’s oceans to human eyes by diving more than 20,000 feet into the ocean. Fresh energy sources, new species—who knows what we’ll find in Earth’s last unexplored frontier?

What's Really in Swimming Pools?
Do you smell chlorine when you swim in an indoor pool? Maybe it's not chlorine after all. Researchers at Purdue University have identified "volatile disinfection byproducts" that can form when chlorine in pool water reacts with sweat and urine. When enough of these byproducts form, they can cause problems for breathing, skin and eyes.

The Explosive Nuclear Question
It's going to be at least another two decades before any commercial models are built, but researchers are at work designing the Generation IV nuclear reactors. Unlike the generation II and III models now in use that use water to cool and control the fission (preventing runaway reactions, subsequent meltdowns and the environmental apocalypse that would result), the leading contender for cooling material for the Gen IV reactors is molten sodium. Not sodium chloride (plain, unreactive table salt), but sodium metal.
