Closer looks reveals axial filaments in sea sponge spicules made up of proteins
(PHYSorg.com Chemistry)

A team of researchers with members from France, Germany and Israel has found that proteins that make up axial filaments are responsible for the means by which sea sponges develop glass skeletons. In their paper published on the open access site Science Advances, the group describes their study of the sea creatures, what they found and why they believe their work could lead to advances in the creation of materials for use in new opto-electronic devices.
