Ultracold Atomic Gas Cooling Technique for Mechanical Quantum Systems

Ultracold Atomic Gas Cooling Technique for Mechanical Quantum Systems

Physicists at the University of Basel have developed a new cooling technique for mechanical quantum systems. Using an ultracold atomic gas, the vibrations of a membrane were cooled down to less than 1 degree above absolute zero. This technique may enable novel studies of quantum physics and precision measurement devices, as the researchers report in the journal Nature Nanotechnology. [More]
Gas Cloud G2 in Galactic Centre May Be Part of More Extensive Gas Streamer

Gas Cloud G2 in Galactic Centre May Be Part of More Extensive Gas Streamer

In November, astronomers at the Max Planck Institute for Extraterrestrial Physics presented new observations of the gas cloud G2 in the galactic centre originally discovered in 2011. These data are in remarkably good agreement with an on-going tidal disruption. As a complete surprise came the discovery that the orbit of G2 matches that of another gas cloud detected a decade ago, suggesting that G2 might actually be part of a much more extensive gas streamer. This would also match some of the proposed scenarios that try to explain the presence of G2. One such model is that G2 is originating from the wind from a massive star. [More]
Breakthrough Prize in Fundamental Physics 2015 Shared by Rensselaer Professor

Breakthrough Prize in Fundamental Physics 2015 Shared by Rensselaer Professor

As a founding member of the Supernova Cosmology Project, Rensselaer Polytechnic Institute professor Heidi Newberg will share the 2015 Breakthrough Prize in Fundamental Physics with members of two competing teams that discovered Dark Energy. The 51 collaborators from the two teams will split the $3 million prize awarded November 9. [More]

Quantum State of a Photon Successfully Teleported Over 25km of Optical Fiber

The world at the quantum level, at the scale of particles too small for the eye to see, is very strange. It's possible, for instance, to have two particles that are "entangled" -- that is, they function as if they were connected, even if they are many miles away from each other. [More]
CERN Launches Open Data Portal for LHC Experiments

CERN Launches Open Data Portal for LHC Experiments

CERN launched today its Open Data Portal where data from real collision events, produced by the LHC experiments will for the first time be made openly available to all. It is expected that these data will be of high value for the research community, and also be used for education purposes. [More]

Computing Quantum Mechanical Behavior Reveals Electronic States of Iron-Sulfur Clusters

Enzymes carry out fundamental biological processes such as photosynthesis, nitrogen fixation and respiration, with the help of clusters of metal atoms as "active" sites. But scientists lack basic information about their function because the states thought to be critical to their chemical abilities cannot be experimentally observed. [More]
Filaments in the Cosmic Web Played an Important Role in Evolution of Distant Galaxies

Filaments in the Cosmic Web Played an Important Role in Evolution of Distant Galaxies

How do galaxies like our Milky Way form, and just how do they evolve? Are galaxies affected by their surrounding environment? An international team of researchers, led by astronomers at the University of California, Riverside, proposes some answers. [More]

Giant Space 'Microphones' May Help Trace Origins of Gamma-Ray Bursts

A team of scientists hope to trace the origins of gamma-ray bursts with the aid of giant space 'microphones'. [More]
Globular Clusters in Smaller Galaxies Have Multiple Generations

Globular Clusters in Smaller Galaxies Have Multiple Generations

Thanks to the NASA/ESA Hubble Space Telescope, some of the most mysterious cosmic residents have just become even more puzzling. New observations of globular clusters in a small galaxy show they are very similar to those found in the Milky Way, and so must have formed in a similar way. One of the leading theories on how these clusters form predicts that globular clusters should only be found nestled in among large quantities of old stars. But these old stars, though rife in the Milky Way, are not present in this small galaxy, and so, the mystery deepens. [More]

Unusual Source of Light Discovered in Distant Galaxy

An international team of researchers analyzing decades of observations from many facilities, including NASA's Swift satellite, has discovered an unusual source of light in a galaxy some 90 million light-years away. [More]
