Better diagnosis and treatment of cancer could hinge on the ability to better understand a single cell at its molecular level. New research offers a more comprehensive way of analyzing one cell's unique behavior, using an array of colors to show patterns that could indicate why a cell will or won't become cancerous.
When researchers at the University of Massachusetts Amherst led by microbiologist Derek Lovley discovered that the bacterium Geobacter sulfurreducens conducts electricity very effectively along metallic-like "microbial nanowires", they found physicists quite comfortable with the idea of such a novel biological electron transfer mechanism, but not biologists.
To engineers, it's a tale as old as time: Electrical current is carried through materials by flowing electrons. But physicists at the University of Illinois and the University of Pennsylvania found that for copper-containing superconductors, known as cuprates, electrons are not enough to carry the current.
Researchers at the University of Southampton's Optoelectronics Research Centre (ORC) have created an artificial material, a metamaterial, with optical properties that can be controlled by electric signals.
The European Commission has identified luminescent materials as a key technology of the next generation. Phosphors are used, for example, in traffic lights, computer screens, smartphones and tablets, Euro banknotes, medical devices, as well as in films for X-rays and light sources.
Studying cellular processes that are implicated in cancer represents one of the main problems of contemporary cell biology and tumour therapy. European scientists are in the process of developing a novel sensing principle at the nanoscale level for monitoring cancer progression.
Odegon Technologies' odour eliminating tags will be available on the British high street from March. The small DeoTags absorb under arm smells via a special military-grade nano-porous fibre sewn into garment lining.
Researchers from Children's Healthcare of Atlanta and the Georgia Institute of Technology have reported the development of a technique that assists in identifying tumors from normal brain tissue during surgery by staining tumor cells blue.
For years, scientists around the world have dreamed of building a complete, functional, artificial cell. Though this vision is still a distant blur on the horizon, many are making progress on various fronts. Prof. Roy Bar-Ziv and his research team in the Weizmann Institute's Material's and Interfaces Department recently took a significant step in this direction when they created a two-dimensional, cell-like system on a glass chip.
Using a new type of camera that makes extremely fast snapshots with an extremely high resolution, it is now possible to observe the behaviour of magnetic materials at the nanoscale. This behaviour is more chaotic than previously thought.
