Perturbations simplify the study of 'super photons'      (via sciencedaily.com)     Original source 

Thousands of particles of light can merge into a type of 'super photon' under suitable conditions. Physicists call such a state a photon Bose-Einstein condensate. Researchers have now shown that this exotic quantum state obeys a fundamental theorem of physics. This finding now allows one to measure properties of photon Bose-Einstein condensates which are usually difficult to access.

Researchers solve 2,000-year-old mystery of the shipworm      (via sciencedaily.com)     Original source 

They bedeviled ancient Greek navies, helped shipwreck Christopher Columbus, aided in the sinking of the Spanish Armada and caused the wharves in San Francisco Bay to collapse into the sea, but until now, scientists have been unable to pinpoint exactly how shipworms -- a family of mollusks -- are able to cause such damage. A team of researchers has discovered that a population of symbiotic microbes, living in an overlooked sub-organ of the gut called the 'typhlosole,' have the ability to secrete the enzymes needed to digest lignin -- the toughest part of wood.

Towards next-gen functional materials: direct observation of electron transfer in solids      (via sciencedaily.com)     Original source 

Nanoscale electron transfer (ET) in solids is fundamental to the development of multifunctional materials. However, ET in solids is not yet clearly understood. Now, researchers achieved a direct observation of solid-state ET through X-ray crystal analysis by fabricating a novel double-walled non-covalent crystalline nanotube, which can absorb electron donor molecules and maintain its crystalline structure during ET. This innovative approach can lead to the design of novel functional materials soon.

Transition-metal-free zeolite catalyst for direct conversion of methane to methanol      (via sciencedaily.com)     Original source 

Direct oxidation of methane to methanol is dominated by transition- or noble-metal-based catalysts, thus making the reaction quite expensive. To make the process efficient and cost-effective, researchers developed a transition-metal-free aluminosilicate ferrierite zeolite catalyst that can produce methanol by using methane and nitrous oxide as starting materials. The new catalyst ensures excellent methanol production efficiency, one of the highest recorded rates in the literature thus far.

Scientists develop 'x-ray vision' technique to see inside crystals      (via sciencedaily.com)     Original source 

A team of researchers has created a new way to visualize crystals by peering inside their structures, akin to having X-ray vision. Their new technique -- which they aptly named 'Crystal Clear' -- combines the use of transparent particles and microscopes with lasers that allow scientists to see each unit that makes up the crystal and to create dynamic three-dimensional models.

This self-powered sensor could make MRIs more efficient      (via sciencedaily.com)     Original source 

MRI scans are commonly used to diagnose a variety of conditions, anything from liver disease to brain tumors. But, as anyone who has been through one knows, patients must remain completely still to avoid blurring the images and requiring a new scan. A prototype device could change that. The self-powered sensor detects movement and shuts down an MRI scan in real time, improving the process for patients and technicians.
