Nano Steps: It looks like we're getting close to having the first nanotech based products reach the market. Molecular machines inserted in your body to keep you free from disease? Nope. Micro-bugs to monitor terrorist cells invisibly? Nope. Tiny robots to scurry about and clean you house while you sleep? Nope.

One of the first nanotech-related breakthroughs consumers will see, for example, is a new type of sunscreen -- expected to start showing up on store shelves within the next year or so -- being perfected by a German company...

I hereby copyright the name "Nanoblock." The Germans can see me if they would like to purchase the rights.

Actually, it does look like there are some cool medical uses coming soon: battery recharging for pacemakers and a more effective treatment for breast cancer. Check it out. You are looking at the iceberg's tip off in the distance.
