The Human Body’s Ability to Repair Wounds

MONG the numerous mechanisms that make human life possible is the body’s ability to heal wounds and regenerate damaged tissue. The process begins as soon as an injury occurs.

Consider: The healing process is made possible by a cascade of complex cellular functions:

Platelets adhere to tissues around a wound, forming a blood clot and sealing damaged blood vessels.

Inflammation protects against infection and removes any “debris” caused by the injury.

Within days, the body begins to replace injured tissue, make the wound contract, and repair damaged blood vessels.

Finally, scar tissue remodels and strengthens the damaged area.

Inspired by blood clotting, researchers are developing plastics that can “heal” damage to themselves. Such regenerating materials are equipped with tiny parallel tubes containing two chemicals that “bleed” when any damage occurs. As the two chemicals mix, they form a gel that spreads across the damaged areas, closing cracks and holes. As the gel solidifies, it forms a tough substance that restores the material’s original strength. One researcher admits that this synthetic healing process currently under development is “reminiscent” of what already exists in nature.

What do you think? Did the body’s ability to repair wounds come about by evolution? Or was it designed?

COMPUTER users generate enormous amounts of digital data that has to be stored for access as needed. Scientists are hoping to revolutionize current methods for digital storage by imitating a far superior data-storage system found in nature—DNA.
Consider DNA, found in living cells, holds billions of pieces of biological information. 'We can extract it from bones of woolly mammoths ... and make sense of it,' says Nick Goldman of the European Bioinformatics Institute. 'It’s also incredibly small, dense and does not need any power for storage, so shipping and keeping it is easy'.
Could DNA store man-made data? Researchers say yes.
Scientists have synthesized DNA with encoded text, images, and audio files, much as digital media stores data. The researchers were later able to decode the stored information with 100 percent accuracy. Scientists believe that in time, using this method, 0.04 ounce (1 g) of artificial DNA could store the data of some 3,000,000 CDs and that all this information could be preserved for hundreds if not thousands of years. Potentially, this system could store the whole world’s digital archive. DNA has thus been dubbed “the ultimate hard drive.”
What do you think? Could the storage capacity of DNA have come about by evolution? Or was it designed?

ive found the healing process takes longer as you get older .............

Yep David, it certainly does, due to our inperfection.
