Linking mitigation to regional economic development
The unprecedented scale and complexity of the relief and reconstruction efforts following the 2004 Sumatra-Andaman Island earthquake and Indian Ocean tsunami have motivated scientists, policy-makers, and development aid organizations to rethink the relationship between natural disaster mitigation and economic development. Two recent reports by the World Bank and the United Nations quantify the global exposure of populations and economic activity to natural hazards. By casting mortality and economic loss in geographic terms, both studies have provided baseline arguments for linking disaster losses to other factors inhibiting economic growth, and for linking hazard mitigation to strategies for sustainable development.
However, the global analysis undertaken in these projects is clearly limited by issues of scale as well as by the availability and quality of data. For some hazards, there exist only 15- to 25-year global records with relatively crude spatial information. Data on historical disaster losses, and particularly on economic losses, are also limited. Nevertheless it is possible to assess in general terms the exposure and potential magnitude of losses to people and their assets in these areas. Such information, although not ideal, can still be very useful for informing a range of disaster prevention and preparedness measures, including prioritization of resources, targeting of more localized and detailed risk assessments, implementation of risk-based disaster management and emergency response strategies, and development of long-term plans for poverty reduction and economic development.

There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?

A team led by Austrian experimental physicist Rainer Blatt has succeeded in characterizing the quantum entanglement of two spatially separated atoms by observing their light emission. This fundamental demonstration could lead to the development of highly sensitive optical gradiometers for the precise measurement of the gravitational field or the earth's magnetic field.
The age of quantum technology has long been heralded. Decades of research into the quantum world have led to the development of methods that make it possible...
