Geckos injected with neural stem cells modified to block cartilage growth developed the skeletal and nervous components normally lacking from regrown tails.

The color morph’s bright yellow hue and its propensity for skin tumors both likely stem from a gene implicated in a dangerous form of human skin cancer, suggesting the animals could make an ideal model for studying the disease.

Surface slapping and side-to-side swinging let geckos sprint across water.

Geckos could help control mosquito-borne diseases, but their effectiveness depends on the environment.

Although it's clearly a lizard, the aptly named thick-tailed gecko (Underwoodisaurus milii) has a bulky backside and is known to bark when in danger. 

Geckolepis megalepis escapes its predators by rapidly detaching its fish-like scales.

What researchers are learning as they sequence, map, and decode species’ genomes

Tiny water-repellent spines on a gecko’s skin help keep the lizard dry in humid conditions.
