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

LIQUID CRYSTALS. "Liquid crystals enable chemoresponsive reconfigurable colloidal self-assembly." Remember liquid crystals in unusual optical phenomena in nature? https://lnkd.in/dCWEe2S 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

SOFT ROBOTS. A pressure differential caused by a charge imbalance between the front and back of the drop is one driver of the liquid metal motor. Also, tiny bubbles from the reaction of aluminium and salt water assist in the movement. https://lnkd.in/d7geFQr View in LinkedIn

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

SOFT LIQUID METAL MOTOR that is self-powered and shape-shifting. "Just a drop of metal alloy made mostly of gallium – which is liquid at just under 30 °C – with some indium and tin mixed in. When placed in a solution of sodium hydroxide, or even brine, and kept in contact with a flake of aluminium for 'fuel', it moves around for about an hour. It can travel in a straight line, run around the outside of a circular dish, or squeeze through complex shapes." https://lnkd.in/dJeGFyP 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.""

COLLOIDAL CRYSTALS. "The inherant tendency for monodispersed lyophobic colloids to self-organize provides a general route to new nanostructured materials." The modern Alchemist's dream. https://lnkd.in/dbmiSb8 View in LinkedIn

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

TWILIGHT ZONE. "Nanometer-sized crystallites (nanocrystallites) can display optical, electronic, and structural properties that often are not present in either isolated molecules or macroscopic solids." One day, the substrate for smart material based Claytronics. " "" " View in LinkedIn
