Researchers test straw house for earthquake resilience
There is a growing realization that we need a different construction method for buildings in earthquake-prone regions — especially if these regions are poor and cannot enjoy the latest in engineering; University of Nevada test straw houses as the solution

New ideas for deflecting Earth-threatening asteroids
As scientists use better equipment to make more accurate observations of space, they find more Earth-threatening objects loitering in Near Earth Orbit; a debate is growing as to the best method to deal with this threat

New design allows for using less steel in concrete beams
NC State researchers discover how to use 30 percent less reinforcing steel in the manufacture of the concrete beams; the success of the project is already drawing interest from the concrete industry

Beads behavior may help in avalanche prediction
Scientists blame the seeming impossibility of predicting the next big avalanche or earthquake on the inherent unpredictability of complex systems; a unique experiment, however, suggests that this idea may be wrong

Obama's budget cuts off most funds for Yucca Mountain repository
The future of the Yucca Mountain nuclear waste repository appears grim; Obama campaigned against the project, which is already more the 10 years behind schdule; new scientific evidence showing that water flows through Yucca Mountain much faster than initially believed raises the prospect that the nuclear waste would leach over time

More than 100 levees in 16 states are in an "unacceptable" state of disrepair
U.S. Army Corps of Engineers gives “unacceptable” maintenance ratings to 114 levees in 16 states; these levees are in such a bad shape, that it can be “reasonably foreseen” that they will not perform properly in a major flood; 30 of the levees are in Arkansas

Dire climate scenario: Mass migrations and war
Lord Nicholas Stern, the eminent economist, says severe climate shifts and sea-level rises would “transform where people can live”: “People would move on a massive scale. Hundreds of millions, probably billions of people would have to move if you talk about 4-, 5-, 6-degree increases” (7 to 10 degrees Fahrenheit)

Engineering institute calls on engineers to take climate change into account
A new report considers four areas of engineering under different climate scenarios: energy, water, buildings, and transport, and how they will need to be adapted to deliver a more resilient and robust adaptive management system

Better detection with self-healing wireless sensor network
New self-forming, self-healing wireless mesh sensor network can detect railway embankment landslides, humidity in art museums, water quality in water treatment facilities — and has military and security applications such as a perimeter network that can detect intrusion through breaking a light beam, or triggering a tripwire, or proximity sensor

Ocean water rising unevenly; Washington, D.C. may be submerged
Rather than spreading out evenly across all the oceans, water from melted Antarctic ice sheets will gather around North America and the Indian Ocean;this is bad news for the U.S. East Coast, which could bear the brunt of one of these oceanic bulges
