Anyone who ever lived near a coast is familiar with the dread "Red Tide" -- a sudden and uncontrollable bloom of algae that turns the water murky red-brown, depletes oxygen and destroys menu plans for shellfish lovers.
Scientists have been looking for ways to control red tide blooms, with varying degrees of success. Now a team of French researchers may have
unlocked a new secret of the microscopic underwater world.
Using fluorescent markers, the marine biologists tracked the life cycle of parasites that live on the red tide plankton. When the algae bloom first occurs, it takes the parasites some time before they can get into the plankton system. During this time the red tide thrives.
However, once the parasites get a "toe-hold" in, they rapidly reproduce, and like the creatures in
Aliens, burst out of the plankton, destroying it in the process. As this cycle continues, the bloom -- and the red tide -- recedes.
Scientists hope that, based on these observations, some day they may be able to control or at least shorten the duration of the plankton imbalance by introducing the Alien-like parasites to a red tide. It's not a complete solutions, but it's another piece in the puzzle.
