World's tiniest mirror

Just as the path of photons of light can be directed by a mirror, atoms possessing a magnetic moment can be controlled using a magnetic mirror. Research investigates the feasibility of using magnetic domain walls to direct and ultimately trap individual atoms in a cloud of ultracold atoms.

Molecular design gains importance in medicine and environmental technology

Biomolecules such as peptides and nucleic acids can nowadays be synthesised relatively quickly and inexpensively. In addition, great progress has been made in the development of methods enabling the directed mutagenesis in microorganisms. These two developments have boosted the design of new, and the reorganisation of known, molecules.

Nanotechnology approach for treating cancer tumors with heat and magnets

Though a valuable weapon against cancerous tumors, radiation therapy often harms healthy tissue as it tries to kill malignant cells. Now, Prof. Israel Gannot of Tel Aviv University's Department of Biomedical Engineering is developing a new way to destroy tumors with fewer side effects and minimal damage to surrounding tissue.
