A novel treatment developed by UCSF vascular surgeons has been used in a first-of-its-kind operation to repair a life-threatening aneurysm in the patients aortic arch, which carries blood from the heart.
In an aortic aneurysm the walls of the aorta, the primary blood vessels leading away from the heart, bulge out like a filling water balloon. Eventually it bursts, usually causing a fatal bleeding episode.
Using a wire-thin catheter, the UCSF team inserted a specially designed graft through the right carotid artery on the side of the neck. The graft, a fabric tube that incorporates metallic threads (to offer structural support), was then guided into the arched part of the aorta, which carries blood to the head and body from the heart. Once in place, this specially designed structure, also called a stentgraft, expanded to reinforce and reline the interior walls of the arch.

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...
Theoretical physicists propose to use negative interference to control heat flow in quantum devices. Study published in Physical Review Letters
Quantum computer parts are sensitive and need to be cooled to very low temperatures. Their tiny size makes them particularly susceptible to a temperature...
