These sea algae pods look a lot like yours... Can algae do that?
Genetically modified algae now can grow non-stop with and without photosynthesis... Maybe it could even grow where the "sun don't shine"?
"We need to know if they can survive and whether they can hybridize or evolve to become more prolific when they get out of a controlled environment,
If they can survive, we also need to know whether some types of genetically engineered blue-green algae, for example, could produce toxins or harmful algal blooms -- or both,
The applications are new and the organisms are less well-known. They range from being very tame 'lab rats' that won't survive in nature to wild organisms that can presumably cross with each other unless some measures are taken to prevent crossing. It's a very new situation."
