Prochlorococcus bacteria are likely the most abundant photosynthetic organism on the planet.

They create a significant portion—10 percent to 20 percent of the atmosphere’s oxygen.

Biologists once thought of these organisms as isolated wanderers, adrift in an unfathomable vastness.

But biologists now think bacteria have been making these structures all along unnoticed.

Researchers from the University of Córdoba , Spain , have discovered nanotubes in marine bacteria.

Scientists watched cells sprout from the tubes and then investigated what they carried.

Moving across these bridges from cell to cell were substances such as amino acids, the basic building blocks of proteins and enzymes and toxins.

Bacteria with streamlined genomes sometimes form interdependent communities with organisms that produce what they need and need what they produce.

Researchers have found that nanotubes can support cooperation among groups of bacteria.

This kind of cooperation is probably more common than people realize, says Conrad Mullineaux , a microbiologist.
