Whilst conducting a new series of experiments involving the analysis of protons, scientists at the US Department of Energy's (DOE) Thomas Jefferson National Accelerator Facility (Jefferson Lab) discovered that the companions protons had inside the atomic nuclei changed the positive particles' internal stru... |

One of the newest areas of research in science today is laser-particle acceleration, a phenomenon that is believed to be of great promise for modern cancer radiotherapy methods. Various energy ranges need to be achieved, in order for the LPA to be effective against specific types of cancer. Just recently, experts at ... |

The defunct Chandrayaan-1 lunar orbiter, the Indian space probe that slammed into the Moon earlier this year because of a glitch, is still useful even from beyond the “grave.” The analysis of the data relayed back by the ESA-ISRO instrument SARA aboard the spacecraft has helped experts at the European Spa... |

Uranium is the heaviest chemical element that can be found in nature. Over the years, scientists have been trying to discover other, heavier chemicals, and their efforts yielded plutonium in the 1940s, which went on to be used for weapons of mass destruction. Others have been discovered since, but our ability to synt... |

Astronomers have finally discovered proof that confirms a long-held belief, namely that the shock waves generated by supernova explosions act like giant and extremely powerful particle accelerators. They came to this conclusion when they recently discovered that cosmic-ray particles, generated only when a massive sta... |

The Interstellar Boundary Explorer (IBEX) spacecraft is the first probe sent to space whose mission is to accurately assess the boundary between our solar system and the surrounding outer space. Launched last October aboard a Pegasus-XL rocket, the craft has recently managed to discover a very peculiar phenomenon, cl... |

After a very long battle with other candidates, Sweden has finally won the honor of hosting Europe's next neutron-science facility, the European Spallation Source. The science complex will be built around a linear particle accelerator, which will accelerate protons to high speeds, and then have them collide into... |

Protons and neutrons are the basic constituents of the atomic nucleus. Understanding the interactions between the nucleons may provide some insight towards understanding the structure of the nucleus in light nuclei and neutron stars alike. An experiment carried out at the US Department of Energy's Thomas Jeffers... |

The Geminga pulsar was created about 340,000 years ago through the supernova explosion of a regular star, inside what is now called the Geminga supernova. It is well known that supernovae can provide with the required energy to accelerate energetic elementary particles into interstellar space, the so-called cosmic ra... |

One of the most intriguing physical puzzles related to quantum physics and particle physics is a property of the protons, which all elementary particles share, called spin. The spin number, or quantum momentum, represents the particle's rotation around its own axis, but unlike the gyroscopic instruments and spin... |

Earth, like many other bodies in space, is constantly being bombarded with streams of highly energetic sub-atomic particles of matter, coming from all directions. But, while some emissions of particles inside the atmosphere can be explained relatively easy, one type of cosmic rays remained, so far, mostly a mystery. ... |

The forces that keep the protons and neutrons together in the nuclei are called strong nuclear forces and they are actually the strongest forces known. They act on small distances and are caused by a type of boson particles, of the hadron family also known as mesons. Mesons are composed of certain combinations of qua... |

The newly discovered particle is part of the meson class of particles, has a non-zero electric charge, and is composed of four quarks. The announcement of the discovery of the new particle was made by researchers at the High Energy Accelerator Research Organization (KEK) in Tsukuba, Japan, and named the exotic partic... |

Heavy atomic nuclei fuse together when they collide and fuse rather repulsing each other and flying apart. This is due to the motion of the internal particles that form the nucleus, as a result of an excited state of the nuclei. By following the models to describe the interactions that take place between two nuclei w... |

This was what a team of Australian and Chinese scientists were trying to find: simple equations describing complex behaviors of atomic systems. This has been the central aim of physics for some time now, and this team says they've got observational evidence of a universal behavior.Peter Drummond and Xia-Ji Liu,... |

A team of scientists working at an experiment called "Dzero" at the Department of Energy's Fermi National Accelerator Laboratory announced the discovery of a new heavy particle, called "zigh sub b" baryon, Îb.This new particle, also known as "cascade b," has a mass six times greater than that of a proton, is el... |

Every observed physical phenomenon can be explained by the four fundamental forces, and the strong interaction is the most complicated one, explaining how particles interact with one another. Fermions are particles with half-integer spin, divided into two groups: quarks and leptons. The quarks make up protons and ne... |
