Colorectal cancer is the second leading cause of cancer deaths in most developed countries. Screening for colorectal malignancies and polyps (which frequently become cancerous) has been shown to lower the number of deaths from cancer. Most cancer societies and preventive task forces recommend regular screening for cancer of the colon.
Physicians often recommend colonoscopy for screening. Unfortunately, this procedure is uncomfortable and occasionally results in perforation of the colon, sometimes leading to death.
CT colonography is a relatively new imaging technology that can be used to examine the large bowel and rectum where these cancers occur. It is a noninvasive technique that reveals cancer lesions and polyps with nearly the same sensitivity and specificity as colonoscopy, without the risks of bowel perforation.

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...
Breakthrough provides a new concept of the design of molecular motors, sensors and electricity generators at nanoscale

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...
