The turnaround was due mainly to one species of batfish, Platax pinnatus, which is comparatively rare on the GBR and was thought to feed only on invertebrates. The event surpr...

Cell death following blood 'reflow' injury tracked to natural toxin

...ells made it. After 15 minutes, PAR-polymer hadn't gone anywhere. But after 30 to 60 minutes, the researchers discovered that much of it traveled right to areas where the switch normally resides. The fate of the cell is irreversible once PAR-polymer sets off the trigger, says Valina Dawson, Ph.D., profe...
