Senior author Hans Straka of Ludwig-Maximilians-University Munich said in a statement: 'The algae actually produced so much oxygen that they could bring the nerve cells back to life, if you will. Scientists then shined light on the tadpoles, prompting the algae to pump out oxygen to nearby cells, similar to the process of photosynthesis. With each heartbeat, the algae moved through the blood vessels to the brain, turning the translucent tadpole bright green. Tadpoles without the ability to breathe were kept alive in a new breakthrough experiment that could potentially save lives of stroke patients when oxygen to their brain is cut off.īiologists at Ludwig-Maximilians-University Munich injected algae into the tadpole's heart, which provided enough oxygen for the tailed amphibian larva to effectively rescue neurons in its oxygen-deprived brain.
