New approach assembles big structures from small interlocking pieces Posted: 15 Aug 2013 11:51 AM PDT Researchers invent a new approach to assembling big structures -- even airplanes and bridges -- out of small interlocking composite components.

Superconducting wire yields unprecedented performance Posted: 15 Aug 2013 11:50 AM PDT The ability to control nanoscale imperfections in superconducting wires results in materials with unparalleled and customized performance, according to a new study.

Voyager 1 has left the solar system Posted: 15 Aug 2013 10:37 AM PDT Voyager 1 appears to have at long last left our solar system and entered interstellar space, says a University of Maryland-led team of researchers. Their model indicates Voyager 1 actually entered interstellar space a little more than a year ago, a finding directly counter to recent articles suggesting the spacecraft was still in a fuzzily-defined transition zone between the Sun's sphere of influence and the rest of the galaxy.

Cosmic turbulences result in star and black hole formation Posted: 15 Aug 2013 10:37 AM PDT Just how stars and black holes in the Universe are able to form from rotating matter is one of the big questions of astrophysics. Now, physicists show how magnetic fields can also cause turbulences within "dead zones," thus making an important contribution to our current understanding of just how compact objects form in the cosmos.

Dynamics of liquid metal particles examined at nanoscale Posted: 15 Aug 2013 08:36 AM PDT Two researchers have demonstrated that using a continuum-based approach, they can explain the dynamics of liquid metal particles on a substrate of a nanoscale.

Options for molecular imaging expanded Posted: 15 Aug 2013 08:36 AM PDT Scientists have demonstrated a new technique for determining the structure of molecules that challenges long-used standards like X-ray diffraction and nuclear magnetic resonance.

Spaceflight alters bacterial social networks Posted: 15 Aug 2013 07:51 AM PDT In two studies biofilms grown aboard the International Space Station bound space shuttle were compared with those grown on the ground. The study results show for the first time that spaceflight changes the behavior of bacterial communities.

Malware bites and how to stop it Posted: 15 Aug 2013 07:50 AM PDT Researchers have devised an approach to virus detection that acts as a third layer on top of scanning for known viruses and heuristic scanning.

Growth of disorder of electrons measured in dual temperature system Posted: 15 Aug 2013 07:49 AM PDT Researchers have succeeded for the first time in experimentally measuring a probability distribution for entropy production of electrons. Entropy production means an increase in disorder when electrons are moved individually between two microscopic conductors of differing temperatures.

Try clapping your wet hands; A physics lesson Posted: 15 Aug 2013 07:48 AM PDT Clap your wet hands. What happens to a thin film of water when it is compressed vertically? Ultimately, oil companies are interested in this research because of the oil separation process.

Quantum teleportation: Transfer of flying quantum bits at the touch of a button Posted: 15 Aug 2013 05:44 AM PDT Hybrid technology makes possible highly reliable transmission of photonic qubits.

Graphene nanoscrolls are formed by decoration of magnetic nanoparticles Posted: 15 Aug 2013 05:44 AM PDT Researchers show how nitrogen doped graphene can be rolled into perfect Archimedean nano scrolls by adhering magnetic iron oxide nanoparticles on the surface of the graphene sheets. The new material may have very good properties for application as electrodes in for example Li-ion batteries.

Millions of tracks at the fingertips of music researchers Posted: 15 Aug 2013 05:44 AM PDT Online digital music services, such as Last.fm and Spotify, contain semantic information produced by users worldwide about millions of music tracks. A new method now enables exploiting this vast source of information in order to understand the processes behind expressions of musical moods.

Galaxies had 'mature' shapes 11. 5 billion years ago Posted: 15 Aug 2013 05:39 AM PDT Astronomers have established that mature-looking galaxies existed much earlier than previously known, about 11.5 billion years ago.
