A Fluorescent Phantom for Small-Animal Imaging Small animals represent vital model systems for the study of organism development and human disease. They are increasingly recognized as powerful discovery tools in genetic, proteomic and cancer research. For example, animal studies have vast utility in studying efficacy and toxicity of novel cancer therapeutics. Until recently, the significant potential of animal studies was untapped because...
Controlled Light Exposure Microscopy for Confocal Imaging Fluorescence imaging of live cells and tissues is a powerful technique that is increasingly finding new applications in the biological sciences.1 However, photobleaching and phototoxicity can present...
Taking It to the Streets with SPR Surface plasmon resonance (SPR) — a label-free technique for measuring biomolecular interactions in real time — benefits a wide variety of applications, from basic science to drug discovery. The...

Reducing pain in phantom limbs Many individuals who have undergone amputation of an arm or leg experience pain in the missing limb — a phenomenon referred to as phantom limb pain. The sensations can seem as real as aches and pains in the rest of their body. To help people deal with this condition, the mirror box was developed more than 10 years ago. The device enables users to interpret motion of their functioning limb as...
