Robotics in Surgery
Surgeons are increasingly turning toward robotic techniques to aid in procedures that require extreme dexterity and minimal invasiveness. Learn about the advantages, disadvantages, and promises for the next generation of surgery provided by the da Vinci Surgical System. d d d d d d d d  d d d d d d d d  d d d d d d d d  d d d d d  d d d d d d d d d  d d d d d  d d d d  d d d  d d d d d d d d d d d d d d d d

Separating Imaginary Worlds
Toddlers have vivid imaginations. A block becomes soap, for instance, when giving a doll a “bath.” Now introduce the teddy bear: will children choose the same block to remain soap in this new make-believe situation?
Cilia Tricks
These tail-like projections found on eukaryotic cells are capable of more than ever realized. In particular, a better understanding of the organelle’s role in disease is providing researchers with instruments to develop potential therapies.
Mitochondria in Aging
Though mitochondria are well-known as the sites of ATP production, research is rapidly revealing additional functions of the organelle. The Shadel lab studies the ways in which mutations in mitochondrial DNA can contribute to aging.
Advanced Glycation Endproducts
This group of complex molecules has been linked to a number of diseases, including diabetes mellitus, atherosclerosis, and Alzheimer’s disease. However, with no natural mechanisms for destroying AGEs known, the question is raised: is there more to AGEs than harmful effects?
