Researchers led by Arizona State University have completed some of the most sophisticated modeling of the effects of climate change and urban centers in the US, and are finding that some of today's proposed solutions will provide only a fraction of relief from the projected heat.

A new technique protects power grids from attacks against utility control systems that can shut down facility operations, trigger longer-term blackouts and even cause permanent physical damage.

A new building material developed at Empa is about to be launched on the market: 'memory-steel' can not only be used to reinforce new, but also existing concrete structures. When the material is heated (one-time), prestressing occurs automatically. The Empa spin-off re-fer AG is now presenting the material with shape memory in a series of lectures.

The fall of Angkor has long puzzled historians, archaeologists and scientists, but now a University of Sydney research team is one step closer to discovering what led to the city's demise -- and it comes with a warning for modern urban communities.

Sydney may soon undergo a transition from a monocentric city with sprawling suburbs radiating from one CBD, to a polycentric model -- one marked by several sub-centres -- according to a recent study led by a multidisciplinary team at the University of Sydney.

Rice University scientists enhance micron-sized titanium dioxide particles to trap and destroy BPA, a contaminant in water with health implications. The robust particles can be recharged for reuse in water remediation.
