A new study reports the first preclinical tests for a novel anti-cancer technology called 'quadrapeutics' that converts current clinical treatments to instantaneously detect and kill only cancer cells. Quadrapeutics combines clinically available drugs, colloidal gold, pulsed lasers and radiation in a novel and safe micro-treatment that improved standard therapy by 17-fold against aggressive, drug-resistant tumors.
Imperfections in the regular atomic arrangements in crystals determine many of the properties of a material, and their diffusion is behind many microstructural changes in solids. However, imaging non-repeating atomic arrangements is difficult in conventional materials. Now, researchers at the University of Vienna have directly imaged the diffusion of a butterfly-shaped atomic defect in graphene, the recently discovered two-dimensional wonder material, over long image sequences.
