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.

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.
Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....
Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.
The quantum computer has fuelled the imagination of scientists for decades: It is based on fundamentally different phenomena than a conventional computer....
An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
