Scientists at the Naval Research Laboratory (NRL) have proposed theoretical models to explain the normal magnetic properties in iron-based superconductors. This research was published in the December 21, 2008 issue of Nature Physics. Their research builds on earlier research they conducted proposing a theoretical model for superconductivity in newly [...]

UK robot sub searches for signs of melting 60 km into an Antarctic ice shelf cavity
Autosub, a robot submarine built and developed by the UK’s National Oceanography Centre, Southampton, has successfully completed a high-risk campaign of six missions travelling under an Antarctic glacier.
Autosub has been exploring Pine Island Glacier, a floating extension of the West Antarctic ice sheet, using sonar scanners to map the seabed and the underside of the [...]

PITTSBURGH—Using rigorous computer calculations, researchers from Carnegie Mellon University and the Carnegie Institution of Washington have established evidence that supercooled silicon experiences a liquid-liquid phase transition, where at a certain temperature two different states of liquid silicon exist. The two states each have unique properties that could be used to develop new silicon-based materials. [...]
The Polymer Chemistry Research Group at the University of Helsinki, Finland, has succeeded in producing nano-sized metallic copper particles. When the size of particles is reduced to a nano-scale (one nanometre being one billionth of a metre), the properties of the material undergo substantial changes. Unlike in bulk materials, in nanoparticles the number of surface [...]
Main federal disaster relief law has fallen behind modern threat levels, NYU professor finds
posted in SM, Science In new research published in the Journal of Homeland Security and Emergency Management, New York University Professor Mitchell Moss explains that the cornerstone Federal disaster relief legislation, the Robert T. Stafford Act, is dangerously out of date, and must be reformed to provide for rapid relief after a catastrophe.

Argonne scientists discover new platinum catalysts for the dehydrogenation of propane
posted in SM, ScienceARGONNE, Ill. (March 13, 2009) — The process to turn propane into industrially necessary propylene has been expensive and environmentally unfriendly. That was until scientists at U.S. Department of Energy’s Argonne National Laboratory devised a greener way to take this important step in chemical catalysis.
“Using platinum clusters, we have devised a way to catalyze propane [...]

Stainless steel replaces platinum in hydrogen producing microbial electrolysis cells
posted in SM, Science Platinum is highly desired in jewelry and as a catalyst, but in both cases it is expensive. Now, Penn State researchers have found a way to replace the platinum catalyst in their hydrogen generating microbial electrolysis cells with stainless steel brushes without losing efficiency.
“Stainless steel brush cathodes can produce hydrogen at rates and [...]
Researchers at the Johns Hopkins Bloomberg School of Public Health have for the first time identified a molecular pathway that triggers an immune response in multiple mosquito species capable of stopping the development of Plasmodium falciparum-the parasite that causes malaria in humans.
By silencing the gene, caspar, the researchers were able to block the development of [...]
