Don't forget to eat your sunscreen?

Dr. Paul Long states: "What we have found is that the algae living within the coral makes a compound that we think is transported to the coral, which then modifies it into a sunscreen for the benefit of both the coral and the algae.  Not only does this protect them both from UV damage, but we have seen that fish that feed on the coral also benefit from this sunscreen protection, so it is clearly passed up the food chain."

Earlier in the year, scientists cracked the genome of two Acropora species: Acropora millepora and Acropora digitifera.  The King's College London team plans to copy the genes responsible for generating these UV-protective compounds and replicate them en masse using bacteria (because culturing this compound in great quantities with coral is impractical).  The scientists can then possibly manufacturer tablets with this compound to create the world's first consumable suncreen pill.  But to start, the team will create a topical lotion for clinical trials on human skin discarded after cosmetic surgery tummy tucks to see how effective these compounds are at protecting against UV.

There are innumerable applications this coral research may make possible.  The research team is also investigating the use of this compound to increase agricultural sustainability, especially in third world countries.  The UV-protective qualities of the coral compound could increase crops' resistance to the intense sunlight of tropical and desert geographies.

The study is funded by the Biotechnology and Biological Sciences Research Council.
