New Portrait of Gum 41 Hydrogen Cloud Created Using Data from WFI on MPG/ESO 2.2-Metre Telescope

This new image from ESO’s La Silla Observatory in Chile reveals a cloud of hydrogen called Gum 41. In the middle of this little-known nebula, brilliant hot young stars are giving off energetic radiation that causes the surrounding hydrogen to glow with a characteristic red hue.

Ultracold Neutrons Help Study Predicted Tiny Deviations from Pure Newtonian Gravity

All the particles we know to exist make up only about five per cent of the mass and energy of the universe. The rest – "Dark Matter" and "Dark Energy" – remains mysterious. A European collaboration lled by researchers from the Vienna University of Technology has now carried out extremely sensitive measurements of gravitational effects at very small distances at the Institut Laue-Langevin (ILL) in Grenoble. These experiments provide limits for possible new particles or fundamental forces, which are a hundred thousand times more restrictive than previous estimations.

Shifts in Material's Atomic Lattice May Not Hinder Onset of Superconductivity

A new study pins down a major factor behind the appearance of superconductivity—the ability to conduct electricity with 100 percent efficiency—in a promising copper-oxide material.

Physicists Present Study Results of Graphene-Based Quantum Superconductor-Metal Transition

The article "Collapse of superconductivity in a hybrid tin–grapheme Josephson junction array'" (authors: Zheng Han, Adrien Allain, Hadi Arjmandi-Tash,Konstantin Tikhonov, Mikhail Feigelman, Benjamin Sacépé,Vincent Bouchiat, published in Nature Physics on March 30, 2014, DOI:10.1038/NPHYS2929) presents the results of the first experimental study of the graphene-based quantum phase transition of the "superconductor-to-metal" type, i.e. transformation of the system's ground state from superconducting to metallic, upon changing the electron concentration in graphene sheet.

Continuous Electron Beam Accelerator Facility Delivers its Highest-Energy Electron Beams

Late on April 1, the crown jewel of the Department of Energy's Thomas Jefferson National Accelerator Facility ("Jefferson Lab") sparkled its way into a new era. Following an upgrade of the Continuous Electron Beam Accelerator Facility, the CEBAF accelerator delivered the highest-energy electron beams it has ever produced into a target in an experimental hall, recording the first data of the 12 GeV era.

Completely New Properties Can Arise at Interfaces of Two Materials

Using DESY's bright research light sources, scientists have opened a new door to better solar cells, novel superconductors and smaller hard-drives. The research reported in the scientific journal Nature Communications this week enhances the understanding of the interface of two materials, where completely new properties can arise.

Intrusive Cluster of Neighbors Influence Diverging Gaseous Garb of Rare, Identical Stars

Much like an environment influences people, so too do cosmic communities affect even giant dazzling stars: Peering deep into the Milky Way galaxy’s center from a high-flying observatory, Cornell astronomers have discovered identical, rare stars whose diverging dusty and gaseous garb are strictly influenced by an intrusive cluster of neighbors.
