A group of engineers from the University of Strathclyde, in Glasgow, says that harnessing solar energy in space would be an efficient method of ensuring that the maximum amount of sunlight can be converted into electricity. The current would then be sent to Earth via lasers. This would indeed be renewable energy fo... |

Invisibility cloaks moved out of the realm of science fiction, and into reality, several years ago, but scientists are still having problems covering some regions of the electromagnetic spectrum. Now, a team of experts says that optical cloaks could be based on nanoscale silicon spheres. The same materials have bee... |

Iapetus, one of the many moons orbiting Saturn, is unusual even among the gas giant's peculiar satellites. When viewed through telescopes, it appears as if it has two colors, and astronomers have been trying to figure out why that is for years. The answer may lie within Earth's ice sheets. Scientists beli... |

A few years from now, astronauts doing laundry in space could find their clothes entirely dry by the time they take them out of the washing machine. This will become possible through the use of microwaves, instead of tumble dryers, experts at the UMPQUA Research Company say.
According to Space, all astronauts will h... |

Scientists at the University of Oregon say that crop circles are very likely not caused by supernatural forces or UFOs, but rather by the laws of physics. These circles are enormous drawings on the ground, usually laid in crop fields, and that are visible in their entirety only from the air. The director of the UO Ma... |

An astronomical survey was recently able to discover three new water masers inside our galaxy, the Milky Way. One of the new batch of masers is arguably the fastest of its type ever discovered. It travels through space at around 350 kilometers per second, which is pretty fast for an object of its size. Another of the... |

For years, aeronautics experts have been trying to find alternatives to the standard space launch – a rocket that is powered by burning chemical fuel. An alternative proposition that scientists are seriously considering now calls for the use of lasers or microwaves beam to launch spacecraft.Under the new approa... |

According to a recent announcement made by astronomers, it would appear that dust particles inside interstellar clouds can spin faster than ten billion times each second. In the attached photo, the red regions are microwave emissions believed to originate from such fast-spinning particles. The phenomenon has thus far... |

Space-based solar power could become a reality soon, if plans to deal with the emerging global energy crisis are developed in time. The world is gradually starting to reach Peak Oil, and governments need to plan ahead to prevent shortages.The alternative forms of energy production that we currently have, such as for ... |

A team of experts managed to create a diode-like device that allows electromagnetic waves to pass in one direction, but prevents them from going the opposite way. The innovation could have a wide array of practical applications. The new diode was constructed specifically for polarized microwaves, the group explains, ... |

Most people know that black holes exist at the core of massive galaxies, where they exert their huge gravitational pull on surrounding matter. But what is generally less known is the fact that black holes can also be produced artificially, although these objects only act like their cosmic counterparts to some limited... |

According to investigators, human teeth are extremely sensitive to recording information about past experiences we may have encountered, in the sense that they store data on the environmental pollution and radiation levels we came across at some point in our lives. Knowing this, a group of researchers is currently wo... |

Far from being the only ones attempting to create an artificial black hole, Chinese researchers recently announced that they were able to produce the first artificial black hole for microwaves. If light in this energy spectrum enters the construct, it can no longer leave it, the team reports. Its accomplishment was m... |

The reason why we are able to see objects around us is because photons traveling through the atmosphere readily bounce off obstacles in their path. Some of them enter our eyes, and leave their impressions on the retina, which then transforms the data in electrical impulses and sends them to the brain, for analysis an... |

The theory that holds the Big Bang responsible for the creation of the Universe is one way of explaining how everything around us came to be, but it also raises questions as to what happened in those early moments, when the basis for all that exists today was set. More specifically, experts wonder what happened in th... |

Many science teams around the globe have worked on creating a viable and portable electromagnetic bomb (e-bomb) over the past few years, one that could easily take out all the electronic systems in a given area, leaving the target dead in the water. However, despite their best efforts, the smallest such devices const... |
