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
Medical diagnostics is searching for substances capable of documenting early on whether a serious disease is developing or what its course will be. In many cases, the treacherous molecules are present only ...
Silkworms spin colored silks while on a 'green' dyed-leaf diet
For some 5,000 years, cultivated silkworms have been spinning luxurious white silk fibers destined for use in the finest clothing. But current dyeing practices produce wastewater that contains potentially ...

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 ...
3D graphene: Solar cells' new platinum?
One of the most promising types of solar cells has a few drawbacks. A scientist at Michigan Technological University may have overcome one of them.
Self-healing solar cells 'channel' natural processes
To understand how solar cells heal themselves, look no further than the nearest tree leaf or the back of your hand.
