             When 
                    you hear the words "technology" and "surfing" 
                    in the same sentence, you might think of the internet before 
                    you think of the ocean. But there are lots of resources online 
                    to help surfers predict when the sweet swells are headed their 
                    way. Find out just how waves are made, learn the basics of
             
              making your own surf predictions
             
             using weather data from the Internet, solve the physics mysteries 
                    of surfing, and more!

             Humans 
                    and nature agree: Low-frequency sonar is the best way to find 
                    things underwater. The problem is that while whales are using 
                    sonar to search for food, the U.S. Navy is using it to search 
                    for submarines. Whale activists say the technology interferes 
                    with whale migration and their search for food. The U.S. administration 
                    says that in the wake of September 11th, tracking submarines 
                    is an issue of national security.

            DNA 
                  isn't just for fingerprinting people anymore. An Australian 
                  vintner has recently started using grape DNA in the labels of 
                  its most expensive wine. The move is a response to a rise in 
                  the number of wine swindlers switching the contents of some 
                  bottles, leaving investors duped until it comes time to uncork 
                  the wine. The technology began as a way to validate tickets 
                  for the Sydney Olympics, and might also be useful in validating 
                  a wide range of items.

            For 
                  nearly 500 years, people have stared at "the lady with the mystic 
                  smile"and been baffled by herespecially by her smile's 
                  apparent tendency to fade, even disappear, and then return. 
                  Now,
           
           
            Harvard 
                  neuroscientist Margaret Livingstone claims to have solved the 
                  Mona mystery.
