Design #60- Mussel Superglue

If scientists study nature to find a better way, doesn’t that speak of design?

Scientists recently announced they have identified 122,500 species of marine life in the oceans. Imagine, all that on day five of creation! Scientists have to admit they are learning many practical things from these creatures. Take, for example, mussel glue.
In spite of many breakthroughs in making new adhesives, most glues we have will not work well under water, even epoxy. Not so with mussels. They can make a glue in a couple of minutes that will work underwater, and will even stick to Teflon as shown in the picture at the right!
Mussels make this glue from two glands. One makes proteins and the other makes a hardener, much like we do with epoxy glue or epoxy paint. The mixture forms a strand that is fastened to a rock or other surface. It makes five to ten different protein strands and cross-links them for greatest strength. The picture at left shows the glue magnified 25,000 times.
Exactly what makes this glue so super was unknown to scientists until about 2003. Research at Purdue University discovered that common blue mussels were using iron found in seawater to create this super glue. They discovered the mussels were able to extract iron from the seawater and “use it to join proteins together, linking the fibrous molecules into a strong, adhesive mesh.” The next step will be to learn how to manufacture synthetic mussel glue for use in such things as surgery or for household needs such as plumbing. The discovery might also lead to a solvent for mussel glue, for some mussels have glued themselves into a lot of trouble! Zebra mussels, for example, have ravaged the Midwest. Not native to the area, zebra mussels have glued themselves to vessels and there, transported to a new environment, they have multiplied out of control. Mussels have also caused much expense to ships by gluing themselves to its sides. It is hoped that a coating of some type could be developed that would combat these problems.
Again, creation leads the way to invention. Scientists puzzle over some complex aspect of life, all the time declaring that it came about through the result of accidents. Think of it; they are working to design something copied from the result of accidents. Does that make sense? In contrast, God said He made it, and the evidence of His handiwork is everywhere!
