AFPs AT A MOLECULAR LEVEL. Analysis at the molecular level of how an AFP might order water molecules into an ice-like lattice that has the specificity and binding strength to irreversibly adsorb the AFP to ice. Brilliant report. http://www.pnas.org/content/108/18/7363.full View in LinkedIn

ANTIFREEZE GENE MIGRATION. "Protein phylogeny showed the potential mobility of AFPs, which appear to have crossed kingdom and domain borders, occurring in Bacteria, diatoms, crus- taceans and fungi. Our results revealed a broad distribution of AFPs not only in polar organisms but also in taxa apparently not related to cold environments, suggesting that these proteins may be multifunctional.""

COLD ADAPTED ENZYMES. "High catalytic activity at low temperatures and high thermolability" "At low temperature, the low kinetic energy of reacting molecules is compensated for by the flexible structures of cold-active enzymes. Flexibility is achieved by a combination of structural features."" "" " View in LinkedIn

OUTER MEMBRANE CHANGES. "Surprisingly, our results show little or no adaptation to low temperature for those parts of the proteins that are predicted to be inside the membrane. However, changes in amino acid composition and hydrophobicity are found for complete sequences and sequence parts outside the lipid bilayer." https://lnkd.in/dDPNjQV View in LinkedIn

ANTIOXIDANTS AND ROS. "At low temperatures, the solubility of gasses and the production of toxic reactive oxygen species (ROS) increase significantly. To counteract this, C. psychrerythraea and D. psychrophila have an enhanced antioxidant capacity owing to the presence of several genes that encode catalases and superoxide dismutases." https://lnkd.in/dfrND2M View in LinkedIn

"QUANTUM ENTANGLEMENT Creates New State of Matter. Half a million ultracold atoms were linked together in the first-ever “macroscopic spin singlet” state. Entanglement is a consequence of the strange probabilistic rules of quantum mechanics and seems to permit an eerie instantaneous connection over long distances that defies the laws of our macroscopic world." http://www.scientificamerican.com/article/quantum-entanglement-creates-new-state-of-matter1/ View in LinkedIn

BIOLOGICAL DISORDERED HYPERUNIFORMITY. "Materials in a state of disordered hyperuniformity are like crystals in that they keep the density of particles consistent across large spatial distances ... But these systems are also like liquids, because they have the same physical properties in all directions ... previously it had only been seen in physical systems like liquid helium and simple plasmas."

NEW STATE OF MATTER FOUND: "embodied by "topological insulators," materials that conduct electricity only on their surfaces. First identified at the ALS in 2007 by a Princeton team led by M. Zahid Hasan, topological insulators have been the subject of intense interest, based on unusual quantum properties that manifest themselves macroscopically." http://www-als.lbl.gov/index.php/holding/481-als-reveals-new-state-of-matter.html View in LinkedIn

QUANTUM SPIN LIQUIDS. "Researchers at MIT have discovered a new state of matter with a new kind of magnetism. This new state, called a quantum spin liquid (QSL), could lead to significant advances in data storage. QSLs also exhibit a quantum phenomenon called long-range entanglement, which could lead to new types of communications systems, and more." https://lnkd.in/dq6j69a View in LinkedIn

NEW STATES OF MATTER are being described every year, changing our tidy simple universe into one of perhaps endless possibilities. I will end our survey of the new states here, as they were, in part, an answer to the seemingly outrageous ascertain that "Blurring the line between materials and mechanics ... may even result in new states of matter." http://esciencenews.com/dictionary/state.of.matter View in LinkedIn
