Peptide oligomers for holographic data storage
Article Abstract:
Peptide oligomers containing azobenzene chromophores, a new family of organic materials, show promise as recording media for holographic storage. The principle behind their use is to utilize the structural properties of peptide-like molecules to impose orientational order on the chromophores and optimize the optical properties of the resultant materials. Thin layers of these peptide oligomers, just a few micrometers thick, can be used to write holographic gratings optically. Holograms show good thermal stability and will not be erased after heating to 180 degrees C for one month.

Bacteria and silica cycling
Article Abstract:
Bidle and Azam have shown that bacteria gnaw into the shells of diatoms significantly hastening their dissolution rates. They have also shown that adding proteases had the same effect as live bacteria, suggesting that a protein coating offers protection from dissolution. It had previously been thought that diatoms protected their surface by secreting mucus. The large susceptibility to dissolution of the shells is confirmed by Bidle and Azam who attribute them to the different architectures of the silica structures.
