In a new research paper, appearing in the latest issue of the journal Meteoritic & Planetary Science, a team of experts from the Monash University, led by Dr. Maria Lugaro, proposes a new explanation for why the chemical composition of the early solar system looks the way it does in geological records. The scientists... |

A lot of people have thankfully heard of carbon nanotubes in recent years, and most of them know that they are incredibly small constructs, built at the nanoscale, and which are made of single layers of carbon atoms, stuck together in the shape of tubes. But not many people know that these tubes, also known as buckyt... |

Nuclear power plants are some of the most polluting structures in the world, and not necessarily as far as the actual amount of material they put out goes. Everyone remembers the Three Mile Island accident, and the Chernobyl reactor meltdown, in the Ukraine, to name just the most important mishaps that occurred since... |

Despite ample opposition by environmentalists and anti-nuclear activists, the Nuclear Regulatory Commission has allowed the Oyster Creek nuclear reactor in South Jersey to continue to operate for more than 20 years, deeming that the threats the machine poses to the environment and its workers are minimal. Debate has ... |

The city of Hanford, in Washington State, houses the oldest nuclear processing sites, and is now known as the place where weapons-grade plutonium was found lying around the dump site, enclosed only in a very shaky safe box. The find, besides eliminating a threat, also completes a piece of history, as the sample now c... |

Over the past few years, multiple concerns have been raised about the safety standards of functioning nuclear facilities, in terms of emissions or potential accidents, such as those at Chernobyl and Three Mile Island. Protesters have significantly increased their activities throughout the world, and especially in the... |

A new type of radioactive isotopes may hold the key to tomorrow's lung cancer cures, says a team of scientists at the Allegheny General Hospital (AGH) in Pittsburgh, U.S. They have tested the new mesh of substances extensively over the past few years, and have come up with very encouraging results. While standar... |

Although being the second most abundant element in the universe, making for up to 23 percent of all ordinary matter, helium is one of the most scarce elements on Earth, having a concentration averaging about 5.2 parts per million in Earth's atmosphere. Some studies even suggested that within a few years, the hel... |

On July 7, eighteen tons of uranium solution containing natural uranium have been accidentally released in the surrounding environment from one of the containment tanks of the Tricastin nuclear power plant, southern France, leading to the contamination of the ground with about 75 kilograms of unenriched nuclear mater... |

Amongst some of the commonest isotopes on Earth, such as carbon-11, nitrogen-13 and oxygen-15, we find the notorious carbon-14 isotope. However, while all the previously mentioned isotopes have half-lives ranging from a few tens of minutes to few seconds, carbon-14 decays much slower having a half-life of about 5730 ... |

Severe drought raging across the southeast regions of the United States will probably determine a temporary reduction in electric power production capabilities of most of the nuclear plants, or even shutdowns, until the water levels in the rivers that supply the lakes near the power plants rise again to their normal ... |

Uranium dioxide is the world's most common radioactive substance, alongside the natural uranium molecule. Most of this nuclear waste results in the nuclear reactors of the nuclear power plants, during the process of nuclear fission, or nuclear fuel 'burning', which involves splitting the uranium atom t... |

There is a general misconception that nuclear power plants produce dangerous levels of radiation during their electric energy production activity, or that they are just another disaster waiting to happen. The truth is that aside the fact that they produce energy in an extremely efficient manner, without emitting any ... |

Remember hydrogen's radioactive isotope resulted in nuclear reactors that we dump all over the place then accuse the nuclear power plants for radioactive poisoning? Well if you do, then you should also know that they finally found some good use for it lately. Tritium is one of hydrogen's three isotopes and... |

Tritium represents one of hydrogen's isotopes. It is radioactive, having a nucleus formed of one proton and two neutrons, while the most abundant isotope of hydrogen, protium, has no neutrons. The half life of the tritium atom is somewhere around 12 years, and the decay reaction results in a helium atom plus in ... |

Nuclear waste is remnant radioactive material resulted from the nuclear weapons program, or from processing in the nuclear power plants, which cannot be further used for other industrial activities. It is usually extremely radioactive, and has half life time in the range of millions of years, thus a solution must be ... |

Although we are used to the round or oval shape of most celestial bodies, some of them are just defying the cosmic laws and display some really weird characteristics. Saturn's moon, Iapetus, is one of these strange appearances, because it looks like a walnut instead of a sphere.The third-largest moon of Saturn ... |

Massive stars, like the Pistol Star, one of the most luminous known stars in the Milky Way Galaxy, are the likely sources of the observed gamma-rays from the isotope iron-60, recently discovered by astronomers.Stars like this giant have 80 to 150 times the mass of the Sun and "lifetimes" of about 3 million years. Un... |
