Electrons behaving like a particle and a wave: Feynman's double-slit experiment brought to life Posted: 13 Mar 2013 06:40 PM PDT The precise methodology of Richard Feynman's famous double-slit thought-experiment -- a cornerstone of quantum mechanics that showed how electrons behave as both a particle and a wave -- has been followed in full for the very first time.

Life in the universe: Foundations of carbon-based life leave little room for error Posted: 13 Mar 2013 03:23 PM PDT Life as we know it is based upon the elements of carbon and oxygen. Now a team of physicists is looking at the conditions necessary to the formation of those two elements in the universe. They've found that when it comes to supporting life, the universe leaves very little margin for error.

'Monster' starburst galaxies discovered in early universe Posted: 13 Mar 2013 11:25 AM PDT Astronomers have discovered starburst galaxies earlier in the Universe's history than they were previously thought to have existed. These newly discovered galaxies represent what today's most massive galaxies looked like in their energetic, star-forming youth.

Mechanical micro-drum used as quantum memory Posted: 13 Mar 2013 11:25 AM PDT Researchers have demonstrated that information encoded as a specific point in a traveling microwave signal -- the vertical and horizontal positions of a wave pattern at a certain time -- can be transferred to the mechanical beat of a micro-drum and later retrieved with 65 percent efficiency.

Surprising control over photoelectrons from a topological insulator Posted: 13 Mar 2013 08:24 AM PDT Electrons flowing swiftly across the surface of topological insulators (TIs) are "spin polarized," their spin and momentum locked. The potential to control electron distribution in spintronic devices makes TIs a hot topic in materials science. Now scientists have discovered another useful surprise. Scientists have discovered how a photon beam can flip the spin polarization of electrons emitted from an exciting new material.

Paraffin encapsulated in beach sand material as a new way to store heat from the sun Posted: 13 Mar 2013 08:24 AM PDT The search for sustainable new materials to store heat captured from the sun for release during the night has led scientists to a high-tech combination of paraffin wax and sand. They have now reported on the heat-storing capability of this microencapsulated sand.

Uncertainty regarding energy prices is hampering investment in energy efficiency Posted: 13 Mar 2013 08:22 AM PDT According to the model developed by BC3 and UPV/EHU researchers, energy price uncertainty is having a negative effect on investment in energy efficiency. Furthermore, they conclude that higher prices of energy and CO2 emission allowances would encourage such investments.

Biochemical engineering: Waste not, want not Posted: 13 Mar 2013 08:17 AM PDT A simple fermentation treatment can convert a by-product of biofuel production into a valuable chemical feedstock for a wide range of biomedical products.

Plasmonics: Model makes light work of nanocircuits Posted: 13 Mar 2013 08:17 AM PDT A numerical simulation predicts the behavior of a component that controls light for faster computing.

Information technology: Improving the health of machines Posted: 13 Mar 2013 08:17 AM PDT Electronic engineers have developed and successfully tested a management system that increases the efficiency of wireless sensor networks for monitoring machine health.

Signal processing: Look-up tables to shoulder the processing load Posted: 13 Mar 2013 08:16 AM PDT Computing tasks for signal processing could be performed more quickly with less power by using look-up tables.

Quantum magnets moving along: Scientists observes coherent propagation of a single spin impurity in a chain of ultracold atoms Posted: 13 Mar 2013 06:54 AM PDT Many discoveries in physics came as a big surprise -- for example the phenomenon, that some materials loose almost all their electrical resistance at low temperatures, or that others become superconductors at unexpectedly high temperatures. In the past it was mainly due to theoreticians to develop models explaining these unusual properties. Unfortunately it is not possible to have a direct look into a solid state crystal and follow up the motion of charge carriers as this process happens at extremely short time and length scales. Scientists have now observed the coherent propagation of single spin excitations in an ultracold quantum gas of strongly correlated atoms.
