No limits to silicon integrated circuits

Microchip processing technology is being updated at faster and faster rates in our age of silicon chip wizardry. By the time you unpack your smart new laptop or digital camera the technology that went into making it is already becoming outdated. But a solution to the problem is now at hand. Researchers working on a project called PICMOS, with EU funding of EUR 2.5 million, have developed new technologies to produce and combine semiconductor microlasers with silicon wave guides for new, efficient and powerful optical connections.

Researchers make first direct observation of 3-D molecule folding in real time

Researchers at Stanford University are looking closer than ever at how the three-dimensional twists and turns in a riboswitch come together by grabbing it and tugging it straight. By physically pulling on this loopy RNA, they have determined for the first time how a three-dimensional molecular structure folds, step by step.

Emissions from photovoltaic life cycles

New photovoltaic technologies, such as the recent introduction of thin-film cadmiumÔ??telluride materials, have nearly doubled the efficiency of solar cells within the past few years. But the methods of making the materials used for photovoltaic cells, whether from silicon, metal, or other material, have raised doubts about the environmental friendliness of these passive energy collectors.
