It's not something that I had really thought about before. Why is that some animals don't get skin cancer? It's quite the contrary actually. Some plants and animals are able to repair themselves. I know that some aquatic animals can regrow some parts of their body and scientist are researching that area.

Kangaroos apparently have a DNA repair enzyme that repairs the damage done to the skin by the sun. It is estimated that some 400,000 Australians will be diagnosed with skin cancer. The enzyme found in kangaroos can repair up 45% of damage caused by the sun. Whilst it's not 100%, it is certainly better than the zero percent we currently have.

They are now working on putting together a 'super cream' that people can slap on after being out in the sun. Unfortunately, it is another indication that we humans are refusing to acknowledge what nature can do to us. Rather than staying out of the sun, or at least covering ourselves when out in the sun, we would rather get burnt and hope that a cream will fix it all.

If the cream only repairs 45% of the damage receives, that means 55% remains and that 55% could be what causes a skin cancer to form. You can read the story here. I guess in the long run, having a cream is better than having no cream and over time, scientist will find a way of boosting that 45% closer to 100%. Human trials are still five years away - at least our kids may have some protection into the future.
