"The fish have proteins in their blood that protect them from frost. That's been long known, but we never understood how these anti-freeze proteins worked."Now, using a technique called terahertz spectroscopy (see Here), scientists discovered that the proteins change the way water molecules behave in the blood. They
"Usually perform a permanent dance in liquid water, and constantly enter new bonds, (but) dance a more ordered dance in the presence of proteins,"the researchers explain in a statement.
