UCLA physicist tests theories of dark energy by mimicking the vacuum of space
Besides the atoms that make up our bodies and all of the objects we encounter, the universe contains mysterious dark matter and dark energy. The latter, which causes galaxies to accelerate away from one another, constitutes the majority of the universe's energy and mass.

Biodiversity: 11 new species come to light in Madagascar
Madagascar is home to extraordinary biodiversity, but in the past few decades, the island's forests and associated biodiversity have been under greater attack than ever. Rapid deforestation is affecting the biotopes of hundreds of species, including the panther chameleon, a species with spectacular intra-specific color variation. A new study by Michel Milinkovitch, professor of genetics, evolution, and biophysics at the University of Geneva, led in close collaboration with colleagues in Madagascar. (2015-05-25)

How the chameleon climbed to the top of the tree
The chameleon's exceptional tree-climbing ability is dependent on vital ball-and-socket joints in its wrists and ankles, according to research published in the open access journal BMC Evolutionary Biology. The study also finds that chameleons have twice the number of wrist and ankle skeletal elements than previously thought, and explains how they evolved to live in the trees. (2015-09-17)

Chameleons' eyes are not so independent
It looks as if chameleon's eyes move independently, however, if the eyes are truly independent, the right side of the brain should only know what the left eye is seeing and vice versa. But it turns out, based on experiments carried out in Israel, that while they can track different objects on opposite sides of their heads, each eye knows where the other is directed, so chameleon's eyes are not independent. (2015-07-08)

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)

Experiment attempts to snare a dark energy 'chameleon'
Is dark energy hard to detect because it's hiding from us? According to a recent theory, hypothetical particles called chameleons vary in mass depending on nearby matter: in the vacuum of space, they have a small mass and large reach, pushing space apart. In the lab, surrounded by matter, they have a large mass and small reach, making them difficult to detect. A UC Berkeley experiment seeks to find chameleons by lessening the screening. (2015-08-20)

Conspicuous social signaling drives the evolution of chameleon color change
In dwarf chameleons, evolutionary shifts in the capacity for color change are associated with increasingly conspicuous signals used in contests and courtship rather than by the need to match different backgrounds. (2008-01-28)

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. Similar to its biological analogue, the synthetic skin reacts to mechanical stimuli by changing its stiffness and color. The scientists see their development as quite promising. The work was published in the recent issue of the Science journal. (2018-03-30)

A flexible color-changing film inspired by chameleon skin (video)
Chameleons can famously change their colors to camouflage themselves, communicate and regulate their temperature. Scientists have tried to replicate these color-changing properties for stealth technologies, anti-counterfeiting measures and electronic displays, but the materials have limitations. Now, researchers have developed a flexible film that changes color in response to stretching, pressure or humidity. They report their results in ACS Applied Materials & Interfaces. (2020-10-21)

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. (2020-01-09)
