Iridescence is a form of structural colour which uses regular repeating nanostructures to reflect light at slightly different angles, causing a colour-change effect.
It is common in nature, from the dazzling blues of peacock's feathers, to the gem-like appearance of insects.
Although using bright flashy colours as camouflage may seem counterintuitive, researchers at the Bristol Camo Lab...
Earlier this year, the last remaining male Northern White Rhinoceros (NWR) died in captivity, nearly cementing the fate of this subspecies for extinction. In the wild, continuing threats of poaching, habitat destruction, and small population size have contributed to the rhinos' status as critically endangered. Yet, novel conservation efforts that make use of cryopreserved genetic...
The case for permethrin-treated clothing to prevent tick bites keeps getting stronger.
In a series of experiments conducted by researchers at the U.S. Centers for Disease Control and Prevention, clothing treated with an insecticide known as permethrin had strong toxic effects on three primary species of ticks known to spread disease-causing pathogens in the United States....
Boldness correlates with the mating success, but not body size or sex, of yellow-spotted monitor lizards roaming the remote Oombulgurri floodplains of tropical Western Australia, ecologists report in the Ecological Society of America's open access journal Ecosphere. But boldness has a cost: bold individuals expose themselves to much higher risk of being eaten by predators...

Golden monkeys have lost so much habitat, they are only found in a handful of national parks in Africa; farming and illegal hardwood trade in Madagascar is gobbling up the island's...
Studies examining animal alarm calls suggest species which require different escape responses for different predators are more likely to have correspondingly different alarm calls, facilitating appropriate escape responses from receivers. However, what causes calls to diversify in less urgent contexts is little examined. "To address this, we examine a quiet contact vocalisation of chimpanzees, the...
