By intersecting a laser beam with a stream of atoms inside a copper box, researchers at the Rice University are able to excite atoms to a level where they become almost as large as the dot at the end of a sentence. This allowed them to emulate the behavior of the Trojan asteroids in our solar system.
These space roc... |

Two researchers from the US Department of Energy (DOE) Sandia National Laboratories (SNL) propose that tiny black holes may be capable of creating the gravitational equivalent of atoms. This may be possible as the dense objects begin to capture particles whizzing around them. Neutral atoms could be captured around su... |

A team of researchers that arguably had too much time on its hands announces that it managed to count the number of atoms in a kilogram of silicon. They did so by dividing the quantity into smaller volumes. In science, this number is known as the Avogadro's constant, and it refers to the atoms that can be found ... |

Imagine a chain composed of a single type of atoms. For argument's sake, say that you are dealing with gold atoms. For many years, physicists and chemists have wondered how hard one has to pull with a specialized device on one of the atoms, so that it separates from the others of its kind. As the issue moves fro... |

One of the basic properties of matter, and the thing that arguably made life on Earth possible, is the fact that its atoms and molecules tend to come together, and structure themselves in various patterns. However, despite all odds, these patterns are not always symmetrical, as one could expect. In fact, at times, en... |
