Rare cancers spreading among sea creatures have scientists perplexed

A LONG TIME ago, though we don’t know how long, a bay mussel somewhere in the Northern Hemisphere developed a leukemia-like cancer. It began as a mutation in a single rogue cell, which copied itself over and over and over again, and spread through the mussel’s hemolymph, the blood-like fluid in its body. 

But then the cancer did something it was not supposed to do, or so we thought: It somehow spread to other mussels through the water. Cloning itself again and again in these new hosts, the malignancy continued to proliferate and infect new individuals. 

Even stranger still, the disease didn’t remain in bay mussels alone: It’s now been found in two other shellfish species on opposite ends of the world: blue mussels in France, and Chilean mussels in Argentina and Chile. 

This finding, described in a paper published Tuesday in the journal eLife, is the latest in a series of studies showing the transmissible cancers are more common than previously believed—especially in the ocean.

I have been a writer for approximately 14 years+ and during that time I was an investigative journalist for a private organization that exposed corruption among charities and other businesses. I also spent time advocating/acting on behalf of and for animal and human rights. Yet now I spend my days writing poems, sonnets and stories. As well as crochet patterns, when I am not doing that I spend a lot of time taking care of my son.
