Anti-counterfeit 'fingerprints' made from silver nanowires
Unique patterns made from tiny, randomly scattered silver nanowires have been created by a group of researchers from South Korea in an attempt to authenticate goods and tackle the growing problem of counterfeiting.
Researchers develop new kind of polymers that can be created using solid-state polymerization of organic dye molecules
Israel researcher: Elusive Biblical blue found
An Israeli researcher says she has identified a nearly 2,000-year old textile that may contain a mysterious blue dye described in the Bible, one of the few remnants of the ancient color ever found.
Golden trap: Highly sensitive system to detect individual molecules

Are window blinds the future of power generation?
Imagine a future where you run household appliances with electricity generated by window blinds. Such a future might seem far-fetched, but not to Deakin University PhD student Gayathri Devi Rajmohan.
New cell component important to tea and wine-making
Scientists have discovered where plants build tannins, complex chemicals used by plants for defence and protection. The source is the tannosome, a newly discovered organelle that is found in most land plants.
Lab-made complexes are 'sun sponges'
In diagrams it looks like a confection of self-curling ribbon with bits of bling hung off the ribbon here and there. In fact it is a carefully designed ring of proteins with attached pigments that self-assembles ...
