A frog living near the noisy springs in central China was found by researchers from the University of Illinois and the University of California to have the ability to tune its ears to hear only certain sound frequencies, as opposed to hearing all the sounds in the acoustic spectrum at the same time, as humans do. Pre... |

Oscillators are extremely important for both electronic and mechanical devices. Quartz watches, computers, radios, clocks would be rendered inoperable without the help of oscillators. The basic idea is that oscillators are required to provide with a constant clock at a given moment. The clock of an oscillator is meas... |

There must have been something about our hearing that enabled us to differentiate speech and music from other sounds. The human ear can detect sound frequencies of 16Hz to 20 kHz, no matter if tones were high or low, near or far. But our ears are simple compared to the remarkable ability of single brain neurons to ma... |

For most average computer users, the hardware layer of their machines is a complete mystery, but for a handful of more advanced users and system administrators, the inner workings of a computer is worth knowing and monitoring in order to ensure an optimal performance level and a long life for the said computer. While... |

The first ever public electric power distribution system appeared in the late 19th century and mostly supplied direct currents, with multiple output voltages, or under the form of alternating current, which reverses the polarity of the current every 20 milliseconds. However, the energy demand and the advantages that ... |

Plastics are durable and degrade very slowly. One of the main advantages of this material is the low price and incredible versatility, which led to a rapid expansion of plastic compounds in almost all industry areas.The problem is that it's made of oil and should petroleum prices continue to rise, so will the c... |

A group of Japanese scientists is exploring new types of electronic nanocomponents for the computing industry, where the silicon seems to have reached the maximum limit of miniaturization. They recently built a highly efficient room-temperature nanometer-scale laser that produces stable, continuous streams of near-... |

Doesn't it bother you that – as unlikely as it may seem – most alien species in the sci-fi productions can speak English, or Japanese, or French, or whatever the language of the show's producers and intended demographic is? Moreover, the same aliens seem to speak their native language when they don't ... |

When it comes to making money, some people will stop at nothing, and that includes anything from selling your own organs for money, to selling debris and calling it "a piece of Intel". Of course, everybody wants to buy land on the Moon, but there is much talk if we actually set foot on it, so sale claims go from anyt... |
