Rising Sea Levels Could Disintegrate Antarctic Ice Sheet

Rising sea-levels could cause the Antarctic ice sheet to break up, even though the air over it will remain chilly enough to prevent significant melting for at least a century, according to a new study by a researcher from Victoria University of Wellington, New Zealand. As part of their stud...

... the cross-linking of the polymer chains is achieved exclusively by means of the proteins. Because proteins can be attacked by proteases, enzymes that disintegrate proteins, these gels are biodegradable. The green fluorescence of the protein is pH-dependent. The gel correspondingly also reacts to changes in pH. I...
