A synthetic chameleon has been developed
An international team of researchers including Dmitry Ivanov, the head of laboratory of functional soft-matter systems, MSU, announced the development of a synthetic chameleon skin.

Polymers that mimic chameleon skin
Biological tissues have complex mechanical properties -- soft-yet-strong, tough-yet-flexible -- that are difficult to reproduce using synthetic materials. An international team (CNRS, Université de Haute-Alsace, ESRF the European Synchrotron, University of North Carolina at Chapel Hill and University of Akron) has managed to produce a biocompatible synthetic material that replicates tissue mechanics and alters color when it changes shape, like chameleon skin. It promises new materials for biomedical devices. (2018-03-29)

Sensing protein wellbeing
The folding state of the proteins in live cells often reflect the cell's general health. Australian scientists have developed a molecular probe that senses the state of the proteome -- the entire set of the proteins -- by measuring the polarity of the protein environment. The fluorescence signal of the probe quantifies unfolding and its chameleon-like color shift maps the cellular regions of enhanced misfolding, says the study published in the journal Angewandte Chemie.

Unheard of life history for a vertebrate
There is a newly discovered life history among the 28,300 species of known tetrapods. A chameleon from arid southwestern Madagascar spends up to three-quarters of its life in an egg. Even more unusual, life after hatching is a mere 4 to 5 months. No other known four-legged animal has such a rapid growth rate and such a short life span. The new research is reported in Proceedings of the National Academy of Sciences. (2008-06-30)
