The American space agency has great plans for the future, including the prospect of colonizing the Moon and sending astronaut expeditions to the Red Planet. However, all of these ambitious plans are heavily reliant on one thing, and that is the ability to produce things off-world. For example, manufacturing space par... |

Scientists at the University of Cincinnati have recently discovered an innovative, new method of controlling the spin orientation of electrons – an area of research known as spintronics – using nothing more than electrical means. This has long since been hypothesized as possible, but has never been scient... |

Graphene, the one-atom-thick sheet of carbon atoms that was discovered in 2004 at the University of Manchester, is the most avidly researched material today in the field of condensed-matter physics. Because electrons flow in a very peculiar way through it, experts believe it may constitute the replacement of choice f... |

The main issue plaguing researchers trying to devise quantum computers today is the fact that it's considerably more difficult to entangle electrons than it is to entangle photons. If that became a reality, then experts could finally use superconductor materials as a source of entangled electrons, which could le... |

The idea that electric “continuous currents” flowed inside small metal rings indefinitely was proposed since the earliest days of quantum physics, in the 1920s and 1930s. At the time, it was stated that the currents were small, but that they flowed through the rings indefinitely, regardless of whether or ... |

Over the years, electron microscopes have generated a wealth of knowledge on many small things, but experts have always resented the fact that the instruments cannot be used to image living samples. The beams of electrons this type of microscope uses to get the job done is very energetic, and can, at best, easily dis... |

In laser sciences, the photoelectric effect is a phenomenon that explains why stimulated light can rip electrons from their orbits around atomic nuclei and carry them away. But this theorem is about to be rewritten, some physicists say. In recent tests, they have noticed that, when using very powerful UV lasers, not ... |

It's common knowledge that gold is one of the most ductile materials.

Well, we know how to turn materials into superconductors; it is about the time to learn how to create superinsulators. We cannot have one without the other, can we? In fact, superinsulators are just the opposite of superconductors. While superconductors experience zero or close to zero electrical resistance, superins... |

Jupiter and Earth, two extremely different planets. One has a solid surface, the other has no surface at all; one is a rocky planet, the other, a massive gas giant, and so on.
