According to CERN, the operator of the Large Hadron Collider (LHC), engineers have recently been able to successfully inject particle beams inside sections of the amazingly large particle accelerator. The world's largest physics experiment was shut down in September 2008, after a leak compromised a section of th... |

The image most of us have of Saturn is that of a gas giant closely surrounded by its rings, which are very thin, yet very wide. Now, astronomers prove us wrong, showing that the planet indeed has another, massive ring around it, which extends as much as 13 million kilometers away from it, around the moon Phoebe. This... |

Scientists at ETH Zurich have recently announced the development of a clever, new way of manipulating hydrogen molecules inside solutions. They are notoriously difficult to steer using electrical fields, because of the symmetrical way that charges are distributed within the ensemble. Details of their accomplishment a... |

Over the past few years, nanomaterials have made it into the “mainstream,” in that they are becoming more and more the natural choice when it comes to constructing devices for a wide range of applications, from better electronics to medical implants. As such, experts are now calling for an assessment of h... |

In 2003, after unsuccessful attempts at explaining dark energy through other means, a group of astrophysicists proposed the “chameleon” particle model to explain the hypothetical form of energy. Basically, what the model stated at the time was that this class of particles was able to change its mass on it... |

The late UC Santa Cruz scientist Donald Coyne and Almaden Research Center expert D. C. Cheng proposed some time ago the hypothesis that all particles in existence were nothing more than mini-black holes. While disregarded at the time, the idea has gained some support in the academic community over the past years, wit... |

The study of subatomic particles is, as everyone knows, mostly conducted in particle accelerators, those huge devices that accelerate protons and electrons to nearly the speed of light, and then smash them together. The ensuing collision breaks the objects into their basic components, and physicists then spend an eno... |

Duke University researchers have found a new way of keeping water pipes clean and free of residues, drawing their inspiration from medicine designed to prevent the formation of clots in the human circulatory system. Basically, they advocate the use of microscopic carbon particles, known as buckyballs, to prevent dirt... |

More and more children in developed countries throughout the world are beginning to exhibit symptoms of asthma on account of high amounts of indoor particulate matter pollution, a factor that has received very little attention from health experts over the years. Now, a new study carried out on children in Baltimore, ... |

Bristol University researchers, working in collaboration with colleagues from Japan, have managed to create an 'entanglement' filter so efficient that it can analyze two particles of light (called photons), and determine if they have the same polarization. If they do, they are allowed to go through, because... |

The Main Injector Neutrino Oscillation Search (MINOS) telescope detector, buried some 700 meters (2,200 feet) below the surface of Soudan, Minnesota, offered its operators a surprise recently, when it proved that it could interpret decays from the stratosphere (which is the upper layer of the atmosphere) and superimp... |

The Large Hadron Collider, the largest high-energy physics facility in the world, has been under constant criticism for its potential effects on the planet, with doom sayers arguing that the colliding two beams of particles at 99.99 percent the speed of light, and at temperatures reaching trillions of degrees, could ... |

A new class of quantum materials is hinted at theoretically by researchers at National Institute of Standards and Technology (NIST) Joint Quantum Institute (JQI) and the University of Maryland. They propose a new method of turning ultracold gas atoms into a supersolid, which is a state of matter that behaves very int... |

The strive to find the mysterious dark matter has been an undertaking that no one returned from successfully, because of the intricate nature of the stuff. In other words, no one can see it, smell it, taste it or touch it, although it resides everywhere around us, and inside us as well. Particle physicists hypothesiz... |

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... |

Last month, a team of physicists made a surprising announcement, in which they claim that they might have found an exotic particle, called the Higgs boson, or the "God" particle, as it plays a key role in explaining the origins of the mass of other elementary particles, in particular the difference between the massl... |

A physics theory states that molecular chaos is an assumption that the velocities of colliding particles are uncorrelated and independent of position. Also called collision number hypothesis, it is useful in making numerous calculations tractable, but so far no one was able to experimentally prove it.Air in any room... |

When cruising in your car, a police laser radar can easily measure your speed and send the ticket to your door, probably along with a picture showing your big grin at 160 km/h (100 mph). But when it comes to observing particles traveling at 1/3 the speed of light - 100,000 km/s - things get a bit complicated.Even the... |

Solar wind is a form of plasma that is constantly ejected from its upper atmosphere and continuously bombards space all around with high-energy electrons and protons that escaped the immense gravity of the Sun in a process that is yet to be fully understood.Fortunately, Earth was a wonderful defense mechanism that u... |

Our universe is made of ordinary stuff: electrons, neutrons, protons. But these particles have some weird cousins that occasionally flash into existence for just moments. The neutrinos is an example of elementary particles, but it displays some unusual properties: it travels close to the speed of light, has no elect... |

The name comes from the fact that Brazil nuts, in a container of mixed nuts, always come on top when the container is shaken, even though they are the largest and heaviest in the bunch. This phenomenon also happens with other large-sized elements in a mix, like cereals in a muesli mix, but nobody has managed to pre... |

From 1990 to 2004, a group of physicists at the Akeno Giant Air Shower Array (AGASA), near Tokyo, Japan, studied the amount of cosmic particles that were hitting Earth and discovered what they claimed to be a tremendous increase in their numbers and in the energy they were carrying, almost 100 times higher than norm... |

The Big Bang is a cosmological model in which the universe has been expanding for around 13.7 billion years, starting from a tremendously dense and hot state, thought to be the best model for the origin and evolution of the universe.

Many people heard the phrase "particle physics" even though some of them don't know much about what it is or what it does. Now, a physicist at Harvard University is proposing a new theory, which he called the "unparticle physics."In a recently published paper, physicist Howard Georgi, a highly appreciated scien... |

Present theories on light explain its nature through the notion of wave-particle duality, that Einstein described in the early 1900s and state that light has both a particle nature and a wave nature. A new theory predicts that light could be made to exhibit properties similar to those of matter, although photons do... |

Pions are some of matter's simplest particles. Built from the same building blocks as protons and neutrons, pions come in three types, designated by electric charge (positive, negative and chargeless). In particle physics, pion is the collective name for three subatomic particles. Pions are the lightest mesons ... |

Since the 1930's it has been apparent that the Universe is made up of more than just the things we can see. It is now widely accepted that a large fraction of the Universe consists of "dark matter" in the form of a new type of fundamental particle. In astrophysics and cosmology, dark matter is matter of unknow... |
