Novel biological electron transfer along bacterial nanowires

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.

Electrons are not enough: Cuprate superconductors defy convention

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.

Novel luminescent materials to reduce global energy demand

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.

Cell on a chip reveals protein behavior

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.
