Perhaps one of the most famous equations in the world, in all scientific fields, is Albert Einstein's theory of relativity, E=mc2. This means that the energy is equal to the mass multiplied by the square speed of light. Recently, an international team whose members come from Germany, France and Hungary, led by L... |

Magnetars are a specific category of neutron stars that possess an unusually strong magnetic field. There aren’t many such celestial objects observed so far, although they could prove extremely interesting to scientists, since their powerful magnetism could have a strange impact on matter. Unfortunately, the mo... |

Detecting water has technologically advanced a long way from using “magic” sticks. Modern science allows using bouncing neutrons in order to detect underground crystal structures, mineral and oil reserves, as well as water presence, in any of its forms. A device capable of doing just that has been develo... |

The Fermi telescope from NASA has managed to depict from the myriads of celestial bodies the only one that emits its pulses in gamma-ray beams alone. It is about 10.000 years old and it sends its light towards Earth at a rate of 3 times per second or, more precisely, once every 316.86 milliseconds. The amount of ener... |

Individuals who have been through a traumatic event often tend to associate certain signals coming from the environment with the occurrence of the bad experience. Such signals are able to trigger fear and even panic attacks, but luckily, the brain has the ability to turn off traumatic feelings related to the memory o... |

Why is there so much matter in the universe, but hardly any antimatter, and where do matter and antimatter actually come from? These are the questions pursued by a team of researchers from the Institut Laue-Langevin in Grenoble, currently preparing to carry out an experiment destined to measure the electrical dipole ... |

The Standard Model describes most of the properties of fundamental particles, however it is far from being perfect. The Standard Model cannot explain why charge is experienced in electron units, nor how certain particles acquire neutral charge and if whether the charge of an atom with equal numbers of protons and ele... |

Nickel 56 is one of nickel's unstable isotopes which is not occurring naturally here on Earth. However, it is formed during the supernova explosion at the end of a star's life. Physicists from the IPN Orsay and the GANIL claim they have been able to compress the nucleus of Nickel 56 for the first time, in o... |

According to new computer simulations, not only rocky moons and planets may have distinctive topographic features such as mountains, but neutron stars may have them as well. The rotational spin around their axis could produce so powerful distortions in the fabric of space-time that they could actually lead to gravita... |

The new neutron detector developed at the National Institute of Standards and Technology is able to measure individual neutrons and their intensities with a sensitivity at least a hundred times higher than that of the traditional neutron detectors. The detector works on the basis of a physical interaction known in th... |

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 ... |

Although on Earth helium gas is relatively rare and mostly extracted from natural gas deposits, in the universe helium is the second most abundant element after hydrogen. The U.S. Department of Energy Argonne National Laboratory have been successful recently in creating a helium-8 isotope, isolate it and measure its ... |

The shocking 9/11 attacks brought back into attention the threat posed by a possible nuclear attack in the United States. In an effort to better detect the smuggle of nuclear material, researchers at Sandia National Laboratories in California designed a new neutron detector, which is effective over larger distances a... |

Neutron stars are one of the few ways a star ends its life. They are formed from the remains of a massive star after it had already exploded into a supernova that condenses into an extremely dense core. They usually have masses 1.35 to about 2.1 times greater than that of our Sun, while being 30,000 to 70,000 times ... |

Our Universe could be made of more than the three space dimensions we can perceive through our limited senses. In addition to length, width and depth, one or more spatial dimensions could exist in exotic places in space.This is exactly what a team of astronomers wants to search for, in the regions of space around de... |

For the first time, scientists have been able to decipher the mysteries of the neutron stars. Using computer simulations to reproduce the conditions in space, they have been able to find out their chemical composition and to learn more about the behavior of the matter under extreme pressures and temperatures.Neutron... |

A neutron star is one of the few possible endpoints of stellar evolution. A neutron star is formed from the collapsed remnant of a massive star after a supernova, and has a mass between 1.35 to about 2.1 solar masses, with a corresponding radius between 20 and 10 km (they shrink as their mass increases), 30 000 to 7... |

Scientists have come up with a new tantalizing hypothesis about a new state of matter and space-time. "Twenty five years ago we thought we understood everything about how matter changes phase. Then along came an experiment that opened up a whole new world", said Xiao-Gang Wen at the Massachusetts Institute of Technol... |
