Growth in the sea comes down to a struggle for iron

...hat it (the molecule) is like a magic bullet. They release it, it binds iron, and then only they have the key to unlock it and get the iron out of it. "Now in reality it's warfare. In some cases other bacteria have figured out ways to get the iron from molecules that they didn't produce. So, they can pirate ...

The secret to longevity in tubeworms

... to propose that L. luymesi also uses its roots to release sulfate back to the microbial consortia from which it draws its sulfide. Without this return of sulfate, the model predicts an average lifespan of only 39 years in a colony of 1,000 individuals; with it, survival increases to over 250 years, matching...
