This experimental setup shows an ultra-low-power wireless communications device that could one day be used in tiny remote sensors. Zerina Kapetanovic, CC BY-ND A new ultra-low-power method of ...

A new ultra-low-power method of communication at first glance seems to violate the laws of physics. It is possible to wirelessly transmit information simply by opening and closing a switch that ...

For continuously gathering information on ocean conditions, one thing that's been proposed is a network of sensors that would transmit data from the sea floor. Changing their batteries, however, could ...

The circuit was designed to provide an alarm system that would transmit signals across the medium wave or the radio wave. The circuit was designed to provide an alarm system that would transmit ...

For the first time, scientists have shown that sound can travel through the emptiness of a vacuum. However, the rule-breaking trick requires specific circumstances and can only be carried out over ...

Traditional computer chips run on electricity, while the emerging photonic chips use light. Now, scientists at Harvard have demonstrated a new kind of chip that transmits data in the form of sound ...

Imagine that you are carefully submerged in a pool of water to the level of halfway up the pupil of your eye. Half of your view is above water and the other half below. Imagine that the water is as ...
