PLOS - sept 2012 - Improvement of Disease Prediction and Modeling through the Use of Meteorological Ensembles: Human Plague in U Climate and weather influence the occurrence, distribution, and incidence of infectious diseases, particularly those caused by vector-borne or zoonotic pathogens. Thus, models based on meteorological data have helped predict when and where human cases are most likely to occur. Such knowledge aids in targeting limited prevention and control resources and may ultimately reduce the burden of diseases.

Cyanobacteria By producing oxygen as a gas as a by-product of photosynthesis, cyanobacteria are thought to have converted the early reducing atmosphere into an oxidizing one, which dramatically changed the composition of life forms on Earth by stimulating biodiversity and leading to the near-extinction of oxygen-intolerant organisms. According to endosymbiotic theory, the chloroplasts found in plants and eukaryotic algae evolved from cyanobacterial ancestors via endosymbiosis. Ecology A cyanobacteria bloom near Fiji Aquatic cyanobacteria are known for their extensive and highly visible blooms that can form in both freshwater and marine environments. Characteristics Cyanobacteria are a photosynthetic nitrogen fixing group that survive in wide variety of habitat, soil and water. Nitrogen fixation Rice plantations utilize healthy populations of nitrogen-fixing cyanobacteria (Anabaena, as symbiotes of the aquatic fern Azolla) for use as rice paddy fertilizer. Ecology

News | October 3, 2013 Imagine H2O, a nonprofit organization that provides a path-to-market platform for early-stage water technology companies. announced Oct. 1 that it is accepting applications from water entrepreneurs worldwide for its 2013 Food & Agriculture Competition. The fifth annual competition seeks to identify and support promising water innovations in the food and agriculture sector. The deadline to submit applications is November 15; applications can be submitted here. Winners will be announced March 22, 2014, at which time the top companies will present their innovations to the program’s pilot partners. On its Food & Agriculture Program web page, Imagine H2O provides two important statistics: A 2012 UN World Water Assessment Program survey indicates that agriculture currently accounts for more than 70% of global water usage.
CIDRAP 22/10/13 Study: More focus on uncertainties would improve disease modeling Mathematical models of infectious disease outbreaks are too often developed and presented with insufficient attention to the uncertainties that underlie them, say British researchers who carefully examined how uncertainties were addressed in a number of outbreak models. The authors, from the University of Liverpool and Lancaster University, concluded that "greater consideration of the limitations and uncertainties in infectious disease modelling would improve its usefulness and value," says a press release yesterday from the Liverpool school. Their report was published last week in PLoS One. Disease models are often used, as the press release notes, to try to predict how outbreaks will progress and to influence response policies. The researchers interviewed 24 scientists, including modelers, infectious disease biologists, public health and veterinary experts, as well as policy makers and other users of model results.

The Authority also discussed key issues raised during the public consultation on the draft guidance which took place from December 2012 to February 2013. Delegates from industry, NGOs, Member State authorities and the European Commission were welcomed to the event by Luc Mohimont, deputy head of the EFSA’s Pesticides Unit, and Karine Lheureux, head of the Applications Desk Unit.

Both are fundamental markers for a number of naturally occurring diseases, and research has shown that diseases from bioweapons have early characterization of influenza-like illness , which typically results in respiratory complaints. We present results for the respiratory time series for the 30 EDs that came online the earliest; these series end in April 2008, and start at times ranging from November 2004 to September 2005.

PLOS 12/03/15 Predicting Epidemic Risk from Past Temporal Contact Data Introduction Being able to promptly identify who, in a system, is at risk of infection during an outbreak is key to the efficient control of the epidemic. The explicit pattern of potential disease-transmission contacts has been extensively used to this purpose in the framework of theoretical studies of epidemic processes, uncovering the role of the pattern’s properties in the disease propagation and epidemic outcomes [1, 2, 3, 4, 5, 6, 7, 8]. These studies are generally based on the assumption that the entire pattern of contacts can be mapped out or that its main properties are known. Although such knowledge would be a critical requirement to conduct risk assessment analyses in real-time, which need to be based on the updated and accurate description of the contacts relevant to the outbreak under study , it can hardly be obtained in reality. Few studies have so far tried to answer this question by exploiting temporal information to control an epidemic through targeted immunization.

MOTHER NATURE NETWORK 18/02/11 How polluted is U.S. drinking water? U.S. tap water is some of the cleanest on Earth, generally safe from the microbes and chemicals that have plagued humans' water supplies for millennia. While much of the planet relies on paltry, polluted drinking water, Americans can fill a glass without fear of cryptosporidium, chromium or chlordane. This hasn't always been the case, however — and in many parts of the country, it still isn't. More than 40 years after the first Earth Day ushered in a new era of environmental awareness, millions of Americans still drink dangerous tap water without even knowing it. The U.S. government had virtually no oversight of drinking-water quality before the 1970s, leaving the job to a patchwork of local laws that were often weakly enforced and widely ignored. It wasn't until Congress passed the Safe Drinking Water Act in 1974 that the newly formed EPA could set national limits on certain contaminants in tap water.
