For the first time, scientists have tracked ultrafast structural changes, captured in quadrillionths-of-a-second steps, as ring-shaped gas molecules burst open and unraveled. Ring-shaped molecules are abundant in biochemistry and also form the basis for many drug compounds. The pioneering study, conducted at SLAC's Linac Coherent Light Source (LCLS), points the...

The world particle physics community convened in Vienna from July 22-29 for the 2015 European Physical Society Conference on High Energy Physics, where the latest results in the field were presented and discussed, including the first results from Run 2 of the Large Hadron Collider (LHC) at CERN. This was...

On August 4, scientists working on the IceCube neutrino experiment at the South Pole reported the observation of a neutrino event that had an energy of more than 2000 trillion electron volts, making it the highest energy neutrino event ever found. The event offers scientists the best hope yet that...

Using the large TRIUMF cyclotron in Vancouver, British Columbia, UCLA researchers have developed a new method to visualize topological insulators, a class of materials that could lead to improved performance in spintronics, at the nanoscale. The new method is the first use of beta-detected nuclear magnetic resonance to study the...

Scientists at Rice University combined titanium and gold to make an itinerant antiferromagnetic metal, TiAu, from nonmagnetic constituent elements. While the uses for this particular magnet have yet to be determined, this discovery could enhance the scientific understanding of magnetism.

On July 14, the LHCb experiment at CERN's Large Hadron Collider reported the discovery of a class of particles known as pentaquarks, which are composed of four quarks and an antiquark. The collaboration has submitted a paper reporting these findings to the journal Physical Review Letters.
