Cross-posted from Risk Sense This week’s Risk Bites video takes a roller-coaster ride through some of the hottest topics in risk science. Admittedly this is a somewhat personal list, and rather constrained by being compressed into a two and a half minute video for a broad audience. But it does touch on some of the more exciting frontier areas in reducing health risk and improving well-being through research and its application. Here are the five topics that ended up being highlighted: BIG DATA   Despite pockets of cynicism over the hype surrounding “big data”, the generation and innovative use of massive amounts of data are transforming how health risks are identified and addressed. With new approaches to data curation, correlation, manipulation and visualization, seemingly disconnected and impenetrable datasets are becoming increasingly valuable tools for shedding new insights into what might cause harm, and how to avoid or reduce it. This is a trend that has been growing for some years, but is now rapidly gaining momentum. Just four examples of how “big data” is already pushing the boundaries of risk science include: High throughput toxicity screening, where rapid, multiple toxicity assays are changing how the potential hazards of new and existing substances are evaluated; “Omics”, where genomics, proteomics, metabolomics, exposomics and similar fields are shedding new light on the complex biology at the human-environment interface and how this impacts on health and well-being; Risk prediction through the integrated analysis of related datasets; and Designing new chemicals, materials and products to be as safe as possible, by using sophisticated risk data analysis to push risk management up the innovation pipeline. CLOUD HEALTH, or C-HEALTH   Hot on the tails of mobile-health, the convergence of small inexpensive sensors, widespread use of smart phones and cloud computing, is poised to revolutionize how risk-relevant
