Danish researchers discover birds with neurotoxin-laden feathers

Two new species of poisonous birds have been discovered in New Guinea's rainforest, containing a neurotoxin similar to that found in South American poison dart frogs. Genetic changes in these bird species allow them to tolerate and store the toxin in their feathers, potentially serving as a defensive mechanism.

Toxin sponges may protect poisonous frogs and birds from their own poisons, study suggests

Researchers have discovered that toxic animals produce 'toxin sponges' to mop up deadly toxins and prevent them from binding to vital proteins. This alternative autoresistance strategy may offer a general means of toxin protection, including the development of antidotes against various toxic agents.
