Contrary to what you may have been taught, water doesn't always freeze to ice at 32 degrees F (zero degrees C). Knowing, or controlling, at what temperature water will freeze (starting with a process called nucleation) is ...

German researchers have discovered how natural antifreeze works to protect fish in the icy waters of the Arctic Ocean from freezing to death. They were able to observe that an antifreeze protein in the fish's blood affects ...

(Phys.org)—A combined team of researchers from Germany and the U.S. has taken a closer look at a type of bacteria that is able to cause ice to form, sometimes even under conditions above the normal freezing point.
Nature has many examples of self-assembly, and bioengineers are interested in copying or manipulating these systems to create useful new materials or devices. Amyloid proteins, for example, can self-assemble into the tangled ...

Neutron scientists have discovered for the first time how 'antifreeze' in arctic fish blood kicks in to keep them alive in subzero conditions. The results could provide benefits for areas as diverse as cryosurgery, food processing ...

(Phys.org) —A team of researches with Queen's University, in Canada has found that the antifreeze protein Maxi, defies the normal expectations of a protein by having a core filled with water molecules. In their paper published ...
Researchers report that they are the first to show in molecular detail how one gene evolved two competing functions that eventually split up – via gene duplication – to pursue their separate destinies.

Though separated by a world of ocean, and unrelated to each other, two fish groups—one in the Arctic, the other in the Antarctic—share a surprising survival strategy: They both have evolved the ability to produce the ...
