Story summary
  • A study in PLOS Biology details how the deep-sea worm Paralvinella hessleri survives toxic hydrothermal vents by converting arsenic and sulfide into orpiment.
  • This adaptation enables the worm to thrive in environments where arsenic can exceed 1% of its body weight.
  • Researchers employed advanced microscopy and chemical analyses to uncover this detoxification process.
