Surgeons at the Stanford University School of Medicine have developed a safe and efficient way to use a surgical robot to perform gastric bypass operations. Their report, published in the August issue of the Archives of Surgery, documents the first totally robotic technique to complete this technically challenging procedure.
The method, developed by associate professor of surgery Myriam Curet, MD, is an improvement on a more conventional technique called laparoscopic surgery. In both instances, specialized tools with cameras attached are inserted through small holes in the patient’s body. But while traditional laparoscopic tools are held in the surgeon’s hand, the robotic tools are operated remotely from a control station.
"It makes the surgery easier," said Curet, noting that the da Vinci robotic surgical system, manufactured by Intuitive Surgical Inc. in Sunnyvale, Calif., offers several advantages over hand-held laparoscopic tools. For example, it has a 3-D camera to aid visualization, as opposed to the 2-D fiber optic cameras used in the conventional tools. The robotic arms also have highly flexible wrists, making precise maneuvers possible.

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
