Rapid color change used for protectioncuttlefish
The skin of cuttlefish changes color rapidly, in order to evade predators, using elastic pigment sacs called chromatophores.
Carbon Nanotube Artificial MuscleIntelligent Polymer Research Institute
Electrolyte-filled twist-spun carbon nanotube yarn that is thinner than a human hair is able to function as a torsional artificial muscle in a simple three-electrode electrochemical system.
Hypaxial muscles aid in respirationaquatic salamander
The hypaxial muscles of some salamanders cause exhalation by actively contracting to increase abdominal pressure and force air out of the lungs.
Rough, hydrophobic surface allows gas-exchangelichen
Pores on lichen surface allow water to roll off it and gas to be exchanged under saturated conditions due to rough surface and hydrophobic compounds.
Apoplasts detoxify ozone (O3) inside leavesplants
Ascorbate located within the apoplasts of plant leaves helps detoxify ozone by reacting directly with the pollutant.
DNA self-repairs after exposure to ionizing radiationBdelloidea
Bodies survive extreme exposure to ionization radiation in certain species of Rotifers of class Bdelloidea by repairing DNA.
Enzymes degrade fluoranthenePleurotus ostreatus
Extracellular enzymes and mycelial growth in Pleurotus ostreatus fungi remove fluoranthene from their environment through biodegradation.
Protein protects eye from infectionhuman
Peptides found in the protein cytokeratin 6A in humans protect from microbial infection by inhibiting bacterial mobility.
Bacterial symbionts provide nitrogenleafcutter ants
Leafcutter ants likely obtain a large part of their nitrogen from symbiotic bacteria living in their cultivated fungal gardens.
