EPA Declares First-Ever Public Health Emergency In Montana
The Environmental Protection Agency on Wednesday declared its first-ever "public health emergency," asbestos contamination near Libby and Troy, Mont., northwestern mining towns, the Associated Press reports. "Asbestos contamination from a now-closed vermiculite mine has been cited in the deaths of more than 200 people and illnesses of thousands more. Before the vermiculite mine was closed in 1990, miners carried asbestos home on their clothes. Vermiculite once covered school running tracks in Libby and some residents used vermiculite as mulch in their home gardens."

Potential Medical Applications For Interactive Data Eyeglasses
For car designers, secret agents in the movies and jet fighter pilots, data eyeglasses - also called head-mounted displays, or HMDs for short - are everyday objects. They transport the wearer into virtual worlds or provide the user with data from the real environment. At present these devices can only display information. "We want to make the eyeglasses bidirectional and interactive so that new areas of application can be opened up," says Dr. Michael Scholles, business unit manager at the Fraunhofer Institute for Photonic Microsystems IPMS in Dresden. A group of scientists at IPMS is working on a device which incorporates eye tracking - users can influence the content presented by moving their eyes or fixing on certain points in the image. Without having to use any other devices to enter instructions, the wearer can display new content, scroll through the menu or shift picture elements. Scholles believes that the bidirectional data eyeglasses will yield advantages wherever people need to consult additional information but do not have their hands free to operate a keyboard or mouse. The Dresden-based researchers have integrated their system"s eye tracker and image reproduction on a CMOS chip. This makes the HMDs small, light, easy to manufacture and inexpensive.

Genetically Engineered Bacteria Compute The Route
US researchers have created "bacterial computers" with the potential to solve complicated mathematics problems. The findings of the research, published in BioMed Central"s open access Journal of Biological Engineering, demonstrate that computing in living cells is feasible, opening the door to a number of applications. The second-generation bacterial computers illustrate the feasibility of extending the approach to other computationally challenging math problems.

Oral Health Center Has Focus On Disease As A Whole

Australia"s premier research centre for all aspects of oral health will be established at the University of Adelaide thanks to a $2.4 million Federal Government grant. The new Centre of Clinical Research Excellence (CCRE) for Oral Health, which will be part of the University"s School of Dentistry, is being funded by the National Health and Medical Research Council (NHMRC). The CCRE Oral Health will be the first research centre of its kind in Australia to focus on all aspects of oral health research and its relationship with the broader health problems that are made worse by poor oral health. "The centre brings together a broad range of researchers with the aim of leading improvements in health outcomes for the community," says Professor Mark Bartold, Co-Director of the new centre. "Past research has focused on dental treatments to repair the damage caused by decay and periodontal disease, as well as the prevention of such diseases. But there has been a lack of research on the role of dental health in people"s overall well-being. A key focus for this new centre will be to investigate the interaction between systemic health and oral disease. "By researching oral health treatments that assist in the management of other diseases, we want to help patients as a whole. In this way, oral health treatments will be able to contribute to the management of patients" other general health conditions, such as cardiovascular disease, pulmonary/respiratory disease, diabetes and arthritis, which are all exacerbated by poor oral health," he says. Other key research areas for the CCRE Oral Health include: * Parental guidance and long-term oral health; * Improving dental treatment in Aboriginal children; * Genetic factors in dental development disorders; * Predicting and reducing mucosal toxicity during chemotherapy; * Use of stem cells in periodontal regeneration. Professor Bartold says the CCRE will also have major benefits for students and early career researchers. "With this new centre, we now have the opportunity to engage more PhD students and postdoctoral fellows in our work. This will be significant both in terms of postgraduate training as well as significantly increasing our research output," Professor Bartold says. Professor Mark Bartold University of Adelaide
