Tiny hairs on the legs of spiders apparently act as individual ears, allowing the creature to feel the moves their prey makes through the air. Thus far, researchers believes that all of these hairs were acting as components for a single, large ear that was the entire exoskeleton protecting spiders.
This idea was ref... |

Washington University in St. Louis (WUSL) investigators announce the development of a new microscale laser, no larger than a pinprick, which is capable of detecting and counting particles at the nanoscale with tremendous precision. Among the most important applications that researchers envision for their new device, ... |

Bats are among the most interesting animals to researchers, mostly because they get around using echolocation, while being completely blind. Though they use approximately the same technique as dolphins, theirs evolved separately, and so comparative studies also yield data on how evolution acted in these two species, ... |

For more than ten years, investigators around the world have been researching a method of producing electricity known as energy harvesting. Unlike conventional and renewable methods, which rely on heat, sunlight, winds or hydrothermal power to produce electrical current, this approach is entirely dependent on making ... |

Phase transitions are among the most important natural phenomena that go on inside the large-scale, 3D world. The concept basically refers to the substances' abilities to change states (liquid, gas, solid) without having their chemical composition altered. One good example of this is the water's circuit in ... |

Blue whales are renowned around the world for the beautiful songs they use to communicate with each other. This has become something of a trademark for the large sea mammals, which are currently endangered from excessive hunting. But, over the years, as the technology to trace and listen to them has become available,... |

Scientists have known for a long time that fingerprints, the tiny ridges that form at the tip of our fingers, serve the purpose of increasing friction between the fingers and the objects we are holding, therefore improving grip. Now, experts propose a new use for the structures, saying that their ridges may be acting... |

A scientist at the Orebro University in Sweden has recently developed a new method of allowing severely hearing-impaired people to regain at least a part of their former sense. The expert, engineering researcher Parivash Ranjbar, has developed a machine that is capable of transposing sounds into vibrations that, when... |

Scientists at the Duke University are among the leading ones in the world when it comes to figuring out ways of tapping into everyday, common actions for extracting electricity. They are especially good at converting forms of energy such as motion in other forms that can power up computers and cell phones, as well as... |

Though our ears are too insensitive to perceive it, the planet is constantly generating a low-frequency humming noise, which was first discovered with instruments in 1998. At a frequency of around 10 millihertz, the sound is far outside our hearing range, as we can only perceive sounds as low as 20 hertz. Now, scient... |

Researchers at the Massachusetts Institute of Technology again proved their worth recently, as they managed to create a low-power, ultra-broadband, fast radio chip that could make wireless devices able to receive phone calls, Internet access, as well as radio and television signals possible. The new chips is shaped a... |

When meerkat cubs are born, the entire group is in attendance and, over the first 3 months or so of life, all of the adults stop at nothing to ensure that their little ones have all they need to survive. Researchers have even observed the fact that the older meerkats even give away some of their food to the begging y... |

It would appear that the teenagers roaming the landscape around Tokyo's Kitashikahama Park district are so poised to destroy the benches and toilets on the public premises, that city authorities have found no other solution to fight this phenomenon except for installing high-frequency sound emitters on various p... |

Scientists at the Massachusetts Institute of Technology have managed to devise a new way of using the carbon-compound graphene for creating a new class of high-performance materials, to be used for next-generation microchips. The speeds that will be achieved with the use of the new stuff will exceed by far those achi... |

Google, along with its partners, is supporting an initiative that is supposed to bring wireless high-speed Internet to every home, for an affordable price. The method is somewhat unusual, although the search giant has been promoting it for five months now, and it consists of allowing Internet providers to use the whi... |
