Nuclear Magnetic Resonance: A Dynamic View of Life

By Florian Celli Florian Celli is a PhD student of biophysics in the Center for Atomic Energy (CEA of Saclay) and the Synchrotron SOLEIL in Paris. He uses nuclear magnetic resonance to study protein dynamics in order to understand their biological role. He co-writes 2 Steps From Science, a website of general science in French and English for students and science fans. Follow on Twitter and Facebook.

Chameleons’ Color Change Secret Revealed

Chameleons are known for the remarkable ability to perform complex and rapid color changes during social interactions. Now, a team of scientists from the University of Geneva (UNIGE), Switzerland, has unveiled exactly how chameleons change their colors. According to the research team’s findings, chameleons can adjust a system of nanocrystals in their skin cells, called iridophores. Better yet, chameleons have two layers of these iridophores, and the second layer reflects infrared light. These two layers can be controlled independently of each other, enabling chameleons to put on their colorful displays.…
