Being as interested as I am with Science news like this, I decided to spend some time and find the original source. The story said the research was done by the Scripps Institute, so I looked around to see if I could find the story on their site, and, well...
Here it is, the original story, written by the news team at the institute istelf, which links to these published Research papers.
However, I cannot access the papers, because you need to pay for access, and neither the original article nor the free abstract of the papers say anything about a sea sponge, so I don't know what to think. I tried going to another news article, unfortunately, that led me to another website that hosted the papers at the same price to view them.
If anyone here could help me out real with this, I'd be happy. I feel there's something I'm missing or not quite getting.
