Dental caries, the disease that causes tooth decay, is infectious, and the mutans streptococci bacteria have long been identified as the primary disease-causing agents. Thanks to numerous scientific advances, tooth decay is not as rampant as it once was, but it is still five times more common in children than asthma and seven times more common than hay fever. And about 25% of the population (in the United States) carries about 80% of the disease burden. So dental caries is still a serious problem, especially for those in the population who are very young, very old, economically disadvantaged, chronically ill, or institutionalized.
For decades, a dental vaccine has been the topic of mucosal immunology and infectious disease research. Host mucosal immunity in pre-clinical and clinical studies has indicated that this immune system can interfere with the processes causing dental caries.
In a symposium during the 82nd General Session of the International Association for Dental Research, five scientists will make a case for the scientific and moral imperative of a vaccine to prevent caries in disadvantaged populations, in the United States and other industrialized countries as well as in developing countries throughout the world. In disadvantaged populations especially, a vaccine is the most plausible and desirable method of preventing disease. Indeed, vaccination is a very significant method of combating an infectious disease whose importance has been recognized in a recent report by the Institute of Medicine.

The WHO reports an estimated 429,000 malaria deaths each year. The disease mostly affects tropical and subtropical regions and in particular the African continent. The Fraunhofer Institute for Silicate Research ISC teamed up with the Fraunhofer Institute for Molecular Biology and Applied Ecology IME and the Institute of Tropical Medicine at the University of Tübingen for a new test method to detect malaria parasites in blood. The idea of the research project “NanoFRET” is to develop a highly sensitive and reliable rapid diagnostic test so that patient treatment can begin as early as possible.
Malaria is caused by parasites transmitted by mosquito bite. The most dangerous form of malaria is malaria tropica. Left untreated, it is fatal in most cases....
The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
