1 00:00:03,269 --> 00:00:13,780 A vast expanse of liquid hope, the oceans are part of America's newest medical frontier. 2 00:00:13,880 --> 00:00:21,588 Its underwater organisms are teeming with potential cures. 3 00:00:21,688 --> 00:00:27,394 Sponges are providing real chemicals, real pharmaceuticals. About seventy percent 4 00:00:27,494 --> 00:00:32,665 of the drugs that we use now have their origin in some natural product, most of 5 00:00:32,766 --> 00:00:37,871 them are plant derived. So, can you imagine how much more there is when two 6 00:00:37,971 --> 00:00:46,646 thirds of the world is colored by water? The potential is unlimited. 7 00:00:46,746 --> 00:00:54,320 The latest medical gold rush takes place beneath the waves. Marine creatures may hold the 8 00:00:54,421 --> 00:01:01,461 key to unlocking the secrets of our own biology. 9 00:01:01,561 --> 00:01:05,632 The horseshoe crab and its eyes are really quite remarkable they become 10 00:01:05,732 --> 00:01:09,869 about a million times more sensitive at night than they are during the day. 11 00:01:09,969 --> 00:01:20,246 We've used that information to be able to get a better sense of how human eyes work. 12 00:01:20,346 --> 00:01:27,220 Aplysia fits the niche for a basic animal that can be used to study memory 13 00:01:27,320 --> 00:01:33,259 and learning. The compound that comes from a shallow water sponge can help to 14 00:01:33,359 --> 00:01:40,667 block the spread of cancer. Scientists view the saltwater wilderness as a 15 00:01:40,767 --> 00:01:46,539 treasure chest of promise for human medicine. I still feel like I'm a kid in 16 00:01:46,639 --> 00:01:49,676 a candy store because marine natural products are amazing. They have such 17 00:01:49,776 --> 00:02:00,420 potential to really be new drugs and yet we have just scratched the surface. 18 00:02:00,520 --> 00:02:07,660 The oceans medical mysteries are as deep as its trenches. What breakthroughs have its 19 00:02:07,760 --> 00:02:11,760 sea life revealed? Are there cures that lie beneath the waves?
