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.…

Lemurs: Where Will They Go?

By Kate Stone Anticipated climate changes are likely to leave a lot of Madagascar’s lemurs looking for new places to live. The results of a new study from Duke University show where lemurs may seek refuge and food as temperatures rise and rainfall patterns change across the 225,000-square-mile island over the next 65 years. Average temperatures throughout the island of Madagascar will rise by as much as 2.6 degrees by the year 2050. Rainfall patterns will probably be altered as well. Anecdotal evidence suggests climate changes are already being felt.…
