(PhysOrg.com) -- For the first time, neutron images in 3 dimensions have been taken of rare archaeological artifacts here at ORNL. Bronze and brass artifacts excavated at the ancient city of Petra, in Jordan were recently imaged in 3 dimensions using neutrons at HFIR's CG-1D Neutron Imaging instrument. The data that is now being analyzed will for the first time give eager archeologists and ancient historians significant, otherwise wholly inaccessible insight into the manufacturing and lives of cultures that once occupied settlements within the Roman Empire, Middle East, and Colonial-period New England.

Researchers at Yale University are studying how two types of nanoscale structures on the feathers of birds produce brilliant and distinctive colors. The researchers are hoping that by borrowing these nanoscale tricks from nature they will be able to produce new types of lasers—ones that can assemble themselves by natural processes.

(PhysOrg.com) -- The SuperB factory, a particle-accelerator to be built in Rome and approved last May by the Italian government was officially launched this past Friday with construction set to begin sometime in the near future.

Researchers from Cornell University in Ithaca, N.Y., have demonstrated for the first time that it's possible to cloak a singular event in time, creating what has been described as a "history editor." In a feat of Einstein-inspired physics, Moti Fridman and his colleagues sent a beam of light traveling down an optical fiber and through a pair of so-called "time lenses." Between these two lenses, the researchers were able to briefly create a small bubble, or gap, in the flow of light.

A time-of-flight detector designed by a research team led by UT Arlington Physics Professor Andrew Brandt could one day significantly boost measurement capabilities at the Large Hadron Collider, or LHC, in Geneva, Switzerland.

(PhysOrg.com) -- Up close, they look simple as can be: a pair of metal bars, each with one side polished to a brilliant shine. One bar faces up, the other to one side.

A University at Buffalo-led research team has established the presence of a dynamic Jahn-Teller effect in defective diamonds, a finding that will help advance the development of diamond-based systems in applications such as quantum information processing.

Chance and probability play a natural role in statistical physics. Inspired by confetti, researchers at the University of Gothenburg, Sweden, gain better understanding of random phenomena and refine the tools that can be used to study them.

In the particle identification business, two pieces of information are vital: energy and spatial location. By measuring its energy you can work out the mass of your mystery particle

Carbon is the fourth-most-abundant element in the universe and takes on a wide variety of forms, called allotropes, including diamond and graphite. Scientists at Carnegie's Geophysical Laboratory are part of a team that has discovered a new form of carbon, which is capable of withstanding extreme pressure stresses that were previously observed only in diamond. This breakthrough discovery will be published in Physical Review Letters.

Diamond, nature's hardest known substance, is essential for our modern mechanical world – drills, cutters, and grinding wheels exploit the durability of diamonds to power a variety of industries. But diamonds have properties that may also make them excellent materials to enable the next generation of solid-state quantum computers and electrical and magnetic sensors.

(PhysOrg.com) -- A simple atomic nucleus could reveal properties associated with the mysterious phenomenon known as time reversal and lead to an explanation for one of the greatest mysteries of physics: the imbalance of matter and antimatter in the universe.

(PhysOrg.com) -- A coupled line of swinging pendulums apparently has nothing in common with an elastic film that buckles and folds under compression while floating on a liquid, but scientists at the University of Chicago and Tel Aviv University have discovered a deep connection between the two phenomena.

(PhysOrg.com) -- Physicists have predicted that under the influence of sufficiently high electric fields, liquid droplets of certain materials will undergo solidification, forming crystallites at temperature and pressure conditions that correspond to liquid droplets at field-free conditions. This electric-field-induced phase transformation is termed electrocrystallization.

Findings that showed faster-than-light travel were released to the public too soon.
