Visualization of DNA-synthesis in vivo

Researchers of the University of Zurich have discovered a new substance for labelling and visualization of DNA synthesis in whole animals. Applications for this technique include identifying the sites of virus infections and cancer growth, due to the abundance of DNA replication in these tissues. This approach should therefore lead to new strategies in drug development.

The smallest conceivable switch

Physicists at the Technische Universitaet Muenchen have created a nano switch based on a single porphyrin ring. If one of two protons from the inside of the ring is removed, the remaining proton can take on any one of four positions, initiated by a single tunnel electron from the tip of a scanning tunneling microscope.

Carbon nanotubes best for 3D electronics

Researchers at Chalmers have demonstrated that two stacked chips can be vertically interconnected with carbon nanotube vias through the chips. This new method improves possibilities for 3D integration of circuits, one of the most promising approaches for miniaturization and performance promotion of electronics.
