Peacock flies

A quick guide on peacock flies, a species of insect where, unusually, both males and females perform dances apparently to attract mates.

Peacock spiders

How has the environment at the Champalimaud Neuroscience Programme influenced your work? We develop and use high resolution, dynamic, quantitative readouts of behavior. This is a real strength at the institute and strongly resonates with me due to the approach I developed while working on the cell biology of trachea morphogenesis. For me, biology is about regulating dynamic processes and if you...

The Peacock Encryption Method

Here is described a preliminary method that enables secure “anti-search-engine” encryption, where the middleman can participate in the encrypted information exchange, without being able to understand the exchanged information, encrypted using a one-way function, as well as being unaware of one of two main exchange participants.

Coloration strategies in peacock feathers.

We report the mechanism of color production in peacock feathers. We find that the cortex in differently colored barbules, which contains a 2D photonic-crystal structure, is responsible for coloration. Simulations reveal that the photonic-crystal structure possesses a partial photonic bandgap along the direction normal to the cortex surface, for frequencies within which light is strongly reflect...
