Size matters for bee 'superorganism' colonies

Scientists have carefully studied the intricacies of how individual organisms live and act together in groups known as biological collectives. In "superorganisms" such as bee colonies, the interactions of the individual members ...

NIST demo adds key capability to atom-based radio communications

Researchers at the National Institute of Standards and Technology (NIST) and collaborators have demonstrated an atom-based sensor that can determine the direction of an incoming radio signal, another key part for a potential ...

Can animals use iridescent colors to communicate?

A new paper from the University of Melbourne reveals how animals use beautiful but unreliable iridescent colors as communication signals. Special adaptations enable animals to control how these shifting colors appear so that ...
