By making observations on a binary system of pulsars a team of researchers from the McGill University in Montreal measured for the first time the spin precession of a celestial body located outside the solar system. Pulsars are a type of neutron stars with strong magnetic fields, emitting electromagnetic radiation th... |

It is widely believed that the Earth and the Moon, the way we know them today, could have been created during an impact between a planet roughly the size of Mars and the 'original' Earth. The collision between the two bodies completely destroyed them both, however gravity eventually pulled the cloud of debr... |

Typical computers today have two main components interacting with each other dynamically in order to process data: the central processing unit and the memory core. The memory core of the computer relies mostly on magnetic components, while the central processing unit uses electrical signals to operate. Nonetheless, U... |

Previously it was believed that the material inside stars is mixed in a homogeneous and predictable way, bringing matter from deep inside the core to the surface and vice versa. However, predictions don't always turn out the way scientists want to. It now seems that increasing the spin rotation of a star renders... |

Magnetic fields are routinely used in medical and scientific investigations to make observations of internal structures. For the first time researchers were able to create a three-dimensional of a magnetic field inside a solid, non-transparent structure through a technique using neutron polarization. The study was co... |

We live in a highly dynamic universe, no surprise here because, if it wasn't, we probably wouldn't be here at all. However, what is weird is that while at large scale things appear pretty natural to us, at a quantum level interactions between particles look more like stories taken out of a science fiction b... |

The silicon transistor was invented in 1947 at Bell Laboratories and most electronic circuits are based on it, such as radios, televisions and computers. Although it is the most reliable electronic component that switches currents, it has great disadvantages. We all know the basic language of the computer circuits is... |

All currently used electronic devices rely on electron charge to function and to transmit information. A new science, called spintronics, tries to switch to using their spin instead of charge, thus potentially continuing the miniaturization process that is rapidly approaching its physical limits with current technol... |

"Spintronics" is an emerging field that deals with the use of the 'spin' of an electron for storing, processing and communicating information and it has known an important recent advance that may one day manifest itself in a new generation of smaller, smarter and faster computers, sensors and other devices... |

Spider silk is extremely flexible, yet it is one of the strongest materials found in nature: at the same thickness, it is stronger than the steel. That's why researchers have been trying for so long to imitate it. Now an Oxford University team shows that if you intend to spin silk like a spider, then you should ... |

Spintronics may well be the next big step in creating a new generation of smaller, smarter and faster computers, sensors and other devices. Due to the fact that the spin of an electron is a property that makes the electron act like a tiny magnet, it can be used to encode information in electronic circuits, computers... |

Recently, scientists were able to polarize noble gases, (rare gases like Helium, Neon, Argon and Xenon) and to take MRI machine pictures of lungs that had inhaled these gases. A new technique can polarize other elements too, with even greater benefits to medical science. Spin polarization is the degree by which the ... |

Steve Irwin made famous through his crocodile wrestling the spectacular spin with its devastating results of these reptiles. Now a team made of a biologist and physicist, based on high-speed video recordings of young alligators spinning realized a scientific approach to this behavior. This way, they created a first m... |

Researchers have measured for the first time a slight force from sunlight that affects the spin rate of the asteroids, a characteristic useful in forecasting fine-tune long-term asteroid orbits and solves the mystery of the rear moonlet displayed by some asteroids. "Sunlight can make asteroids spin so fast they break... |
