For the first time since the early days of the space program, in the early 1950s, the American space agency, NASA, will be conducting a series of tests on monkeys. The goal of the experiments will be to test and see whether their complex physiology, which is very similar to our own, could endure the rigors of a long-... |

Scientists at the American space agency are currently getting ready to perform a new series of radiation tests on a group of squirrel monkeys. The study will attempt to determine the possible effects that prolonged radiation exposure may have on astronauts during long-duration spaceflight to other planets, such as to... |

According to a group of researchers, it may be that the earliest forms of life on the planet might have been made possible by the influence of thousands of small, nuclear fission reactors blasting everything around them with radiation. The model would account for the reason why a radioactive substance has all but dis... |

Many astronomers have speculated that the peculiar distribution of certain forms of gamma-rays in our galaxy, the Milky Way, may be evidence to support the presence of some form of undetectable “dark matter,” which influences its spread patterns. But these theories are disproved by two new scientific pape... |

Almost everyone who is interested in space has heard about black holes, the mysterious structures in the Universe, which have the power to make massive galaxies spin around them. Up until now, these formations have been divided in only two classes – small or supermassive – although the existence of a thir... |

Another idea coming from the SF culture is moving in the direction of becoming a reality: spaceship shields.

Usually, nuclear reactors use multiple stages to turn radiation into electrical energy. For example, first, uranium nuclei are split through nuclear fission, when energy is released in the form of heat and additional radiation. The heat resulted from the nuclear reaction is then used to turn water into steam, which i... |

It's a fatality stalking women. Breast cancer is the cruelest killer cancer in women and radiation therapy is one of the main weapons used against it.
