redOrbit Staff & Wire Reports - Your Universe Online A new technique which uses supercooling to preserve human transplant organs could drastically increase their viable preservation duration, according to new research appearing in the June 29 edition of the journal Nature Medicine. In the study, senior authors Dr. Martin Yarmush and Dr. Korkut Uygun of the Massachusetts General Hospital Center for Engineering in Medicine (MGH-CEM) and their colleagues explain that they used a...

The secret life of water just got weirder. For years water has been known to exist in 15 phases -- not just the merry threesome of solid, liquid and gas from grade school science. Now, University of Utah chemists have confirmed the coexistence of ice and liquid after water crystallizes at very low temperatures. They describe their work in the June 21 issue of the Journal of Chemical Physics, which is published by the American Institute of Physics (AIP). It takes more than a swizzle stick and...

Supercooling, a state where liquids do not solidify even below their normal freezing point, still puzzles scientists today. A good example of this phenomenon is found everyday in meteorology: clouds in high altitude are an accumulation of supercooled droplets of water below their freezing point. Scientists from the Commissariat à l'Energie Atomique et aux Energies Alternatives (CEA), the Centre National de Recherche Scientifique (CNRS) and the ESRF have found an...

By Phillips, Vaughan T J DeMott, Paul J; Andronache, Constantin ABSTRACT A novel, flexible framework is proposed for parameterizing the heterogeneous nucleation of ice within clouds. It has empirically derived dependencies on the chemistry and surface area of multiple species of ice nucleus (IN) aerosols. Effects from variability in mean size, spectral width, and mass loading of aerosols are represented via their influences on surface area. The parameterization is intended for application...

TEMPE, Ariz. -- Water has some amazing properties. It is the only natural substance found in all three states "” solid, liquid and gas "” within the range of natural Earth temperatures. Its solid form is less dense than its liquid form, which is why ice floats. It can absorb a great deal of heat without getting hot, has very high surface tension (helping it move through roots and capillaries "” vital to maintaining life on Earth) and is virtually incompressible. A less...

WASHINGTON -- The latest research on water - still one of the least understood of all liquids despite a century of intensive study "“ seems to support the possibility that cells, tissues and even the entire human body could be cryopreserved without formation of damaging ice crystals, according to University of Helsinki researcher Anatoli Bogdan, Ph.D. He conducted the study, scheduled for the July 6 issue of the ACS Journal of Physical Chemistry B, one of 34 peer-review journals...
