The eyes may be the window to the soul, but many scientists would say the mouth is the window to the body.
Saliva and other oral substances are now emerging as the bodily fluids of choice for physicians, dentists and drug testers, researchers said today at the 2005 Annual Meeting of the American Association for the Advancement of Science (AAAS). Saliva and other oral fluids (from the cheek and gum surfaces) contain many of the same proteins and other molecules that blood and urine do. Some of these molecules can reveal the presence of diseases such as cancer. Others can be used to predict the number of cavities in a persons teeth and perhaps even where in the mouth the cavities will develop, according to new research.
Saliva is also relatively easy to collect, since spitting into a cup doesnt require needles and can be done while a doctor or drug tester watches. As the panelists explained, researchers are making progress in both developing the technology for testing saliva and identifying the molecules, or "biomarkers," that reveal disease.

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
Researchers from the Institute of Organic Chemistry and Biochemistry of the CAS (IOCB Prague), Institute of Physics of the CAS (IP CAS) and Palacký University...
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...
