A group of investigators from the University of Texas in Dallas announces the development of a new class of carbon nanotubes that can act as speakers when placed inside small sheets. The instrument could potentially be used for a wide variety of applications, ranging from sonar to the creation of noise-canceling spea... |

The huge diversity in body shapes and sizes that modern-day whales exhibit have always puzzled researchers. They learned some time ago that creatures ranging from porpoises and dolphins to whales shared a common ancestor, but the way in which these types of animals branched out from this early ancestor has remained a... |

The Autonomous Underwater Vehicle (AUV) Autosub6000 is one of the latest, deep-sea exploration vehicles to come out of the United Kingdom. Originally designed to have a maximum diving depth of 6,000 meters, it has been recently tested – at a number of rough locations – at a depth of 3.5 miles (5.63 kilome... |

Regularly, for calibrating underwater devices such as sonars and communication arrays, engineers need to generate some noise at a distant location, and then fine-tune their instruments to that specific noise. But generating the sound is a fairly complex process, which is about to be made a whole lot simpler through t... |
